Mark Benda: Moulding Master

By James Florence, Diamond Certified Program Reporter

CONCORD — Mark Benda spent the first part of his professional life working with cakes and other confectionary creations, so it’s no wonder that when he decided to switch to the building trades, he chose the one closest to his prior specialty. “I got into culinary arts in high school and went to culinary school in Hyde Park, New York, before coming to California to work as a pastry chef at the Fairmont Hotel,” he recounts. “After my wife and I had our first child, I decided to look into a career with daytime hours and more scheduling flexibility. I ended up enrolling in a carpenter apprenticeship program, where I learned everything from laying concrete to finishing work to commercial moulding.”

Soon after, a chance interaction set Mark on his primary professional path. “I was building a fence when a woman stopped in her little Buick Regal and asked me if I knew how to do crown moulding,” he remembers. “I told her I did and she asked me to follow her to her house, where I gave her an estimate and subsequently did my first residential moulding job. As it turned out, she was an interior decorator named Diane, and after I completed her job, she started referring me to her clients and neighbors. Diane and I became great friends, and she was actually the one who encouraged me to get my license and go into business for myself. It’s amazing how meeting one person can completely change the course of your life.”

Today, as owner of Moulding Masters of California, Mark says he enjoys the creative expression his job allows for, and he draws a parallel between his current specialty and his previous livelihood as a pastry chef. “Like cake decorating, I have a blank surface to work with, and I get to deal with elements like color and texture. I like the fact that my job allows me to apply my creative abilities and make art, not to mention the sense of accomplishment I feel after completing a project.”

Originally from Cleveland, Ohio, Mark resides today in Walnut Creek with his wife, Rosie, and their sons, Dominick and Gabriel. “Like me, my boys are interested in the art of building,” he says. “Both of them have taken woodworking classes in school for the last four years, and Dominick is planning to study construction management in college next year.”

Outside of work, Mark engages in a variety of pastimes, from gardening and cooking to getting outdoors with his family. “Everyone in our family likes doing outdoor stuff, which is neat,” he says. “One of our favorite spots is a beach house in Aptos, where we go a couple times a year to hang out and relax. I also enjoy going on fly fishing trips with my sons and just having some time to bond with them.”

In his life and career, Mark espouses the importance of doing what you love. “I think it’s important to find what you’re passionate about and do it, even if you aren’t getting paid for it,” he affirms. “For me, I enjoy going to work every day and improving people’s homes. Sometimes it’s hard to see the impact I’m making because I’m on the inside looking out, but when a customer compliments me for turning their drab living room into a homier, more beautiful space with moulding and paint, it’s very satisfying and revitalizing.”

When asked what his future retirement might look like, Mark doesn’t have a clue. “I have no plans to retire,” he says. “I really enjoy my work and plan to keep doing it until I’m an old man. Hopefully, my sons will take over the business at that point and make it even better.”

Ask Me Anything!

Q: If you could time travel, would you go to the past or the future?
A: The past, because of the old world craftsmanship. Back then, it was less about production and more about artistic expression.

Q: What’s your favorite local restaurant?
A: Minamoto Restaurant in Concord.

Q: What were you most known for in high school?
A: Culinary arts. I worked in a school co-op program, so I went to school until 11am and then worked in a restaurant until 7 or 8pm.

Q: Do you collect anything?
A: I collect fishing equipment, old woodworking tools and coins.

Q: What was your favorite toy as a child?
A: My Red Ryder BB gun.

Know What You Want
List What You Want Before Calling Contra Costa County Trim Installers

Having quality moulding and trim installed by good conractors doesn’t happen by chance. Instead, a successful job comes with research and careful decision making.


Start by looking over your home, whether or not you currently have crown moulding or decorative trim, and thinking about what your ideals are. Do you need replacement moulding and trim? Or do you want to add decorative trim and crown moulding to dress up rooms that look plain or boring? Do you have specific ideas of what types of moulding or trim you’d like, or do you need a contractor to walk you through your choices?


Having a clear vision of what you want will help increase your chances of finding a contractor who can meet your needs and give your home the look you want.


Use the questions below to make a list of your priorities, wants and needs before you talk with Contra Costa County trim installers.

  1. Do I want a Diamond Certified moulding and trim installation company that is rated best in quality and backed by the Diamond Certified Performance Guarantee?
  2. Which areas of my home need to new moulding and trim installed (i.e. crown moulding throughout the house, new baseboards and trim in the kitchen, custom moulding or trim in the bedrooms, exterior trim or molding, etc.)?
  3. Are there any changes or repairs my home needs before the installation of new moulding or trim (repairing wall damage, texturizing or painting the walls, new windows and doors that will need to be trimmed after completion, new floor installation or floor refinishing that will require new trim or mouldings, etc.)?
  4. What is my budget for new house trim or new moldings?
  5. Am I looking for decorative moulding and trim, or will I be happy with plain trim?
  6. Do I need to have my moulding & trim contractor install flexible crown moulding in areas that are uneven?
  7. Do I want to maintain the same color scheme in the rooms I’m having trimmed, or do I want frequent or drastic color changes in the future? (This may change the type and color of the moulding and trim you want. For example, you may choose a neutral trim and crown moulding color or natural wood that will compliment any paint color rather than one to match the current paint color.)
  8. Do I plan to live in this home long-term? Or is this a house I am going to to sell or a rental property that will have new occupants?
  9. What personal and professional characteristics would I like my Contra Costa County trim and crown moulding contractor to have? (These may include good communication skills, promptness, honesty, dependability, knowledgeably of materials and installation techniques, and cleanliness.)

What To Ask In Person
Ask About Your Options with Contra Costa County Moulding & Trim Contractors

Before hiring a decorative trim and crown moulding contractor in Concord, Richmond, Antioch, Walnut Creek and Pittsburg and the rest of Contra Costa County.

You’ll want to have a list of questions to ask so that you leave each in-person meeting with all of the information you need to decide which local decorative trim and molding company is the best fit for you.

The sample questions below will get you started.

  1. What materials do you recommend for my new crown molding and trim? (This may include hardwood, wood, MDF, polyurethane, urethane, Styrofoam and other materials.)
  2. Will you create custom trim and moulding, or do I have to choose from a catalog of existing shapes and features?
  3. Can you stack prefabricated pieces of crown molding and trim to create custom-looking baseboards, crown moulding and details at less expense than fully custom molding?
  4. Can you deal with uneven surfaces and damaged areas so they look like new again? (This is an especially important question to ask if your home is older or the area you want new moulding or trim installed has been damaged.)
  5. How will the moulding and trim be installed and finished?
  6. Will you and your employees do all of the installation and finish work, or will I need to hire someone else to provide some or all of those services?
  7. What are the finishes I can choose from? Will you finish the trim before installation or after? If you plan to finish the materials before installation, will the finish work be done in my home or at your shop?
  8. How long is the expected wait time between ordering the new crown molding and trim and having it installed?
  9. How long will the crown molding and trim installation process take?
  10. Can I be in my home during the installation process, or will my family and I have to temporarily vacate the premises?
  11. Will you let the moulding rest in my home for at least 24 hours before installation to avoid unnecessary cracking and shrinkage after installation?
  12. Are the moulding and trim installation costs included in the material cost you’ve quoted me?

  • What To Ask References
    Interview References Who Know the Moulding and Trim Company Best

    It’s best to choose a Diamond Certified moulding and trim installers because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from moulding and trim installers in Contra Costa County and the greater Bay Area, you can have confidence choosing a Diamond Certified company.

    Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified moulding and trim company that serves San Ramon, Danville, Brentwood, Martinez and Pleasant Hill or your area, you’ll have to do some research on your own.

    If you do, it’s wise to call some references provided by your moulding and trim installers. Keep in mind, though, that references provided to you by moulding and trim installers are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are hand chosen instead of randomly selected from all their customers.

    If you do call references on your own, specifically ask for a list of the crown moulding and decorative trim company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    Then, call each of the references and ask them questions that will give you more information

    1. Were you satisfied with the services you received from _(Contra Costa County moulding and trim company name)_?
    2. What type of trim and moulding work did they do for you (i.e. custom crown moulding and trim, decorative moulding, molding and trim for cabinets, door moulding, window trim, repainting and replacing damaged trim, baseboard replacement, wainscoting and chair rail installation, etc.)?
    3. Did this trim contractor give you a full description of your options, both in terms of materials and finish work?
    4. Did this company finish your new molding and trim for you, or did you have to hire another company to stain, paint or finish it correctly?
    5. Did the trim & moulding service you hired finish the work on time?
    6. Did the contractor keep you informed about the status of the project? Or did you have to call or email them in order to get updated information?
    7. If you live in a smaller area such as Vine Hill, Port Costa, Rheem Valley, Bethel Island, Briones, Alamo, Walnut Heights, North Richmond, Hercules, or other rural areas, did the trim and moulding service you hired charge extra to travel to your home?
    8. Did the contractors and employees clean up after completing the job?
    9. When you need new trim or moulding work in the future, will you consider hiring this company again?
    10. What did you like best about this Contra Costa County moulding and trim service?
    11. Was there anything that surprised you about this company or their work?
    12. Would you recommend this crown molding and trim company to your friends and family?

  • How To Work With
    Benefit from Your Agreement with Local Decorative Moulding & Trim Contractors

    Once you’ve chosen a local trim and moulding installation company that meets your needs, it’s the perfect time to ask for a written contract to solidify your working relationship. This contract should include written details on the cost, quality and materials to be used, installation details, job start date and intended completion date.

    Before you sign a contract or estimate, be sure you’ve read and completely understand all terms and limitations. The contract you sign is binding, and should protect your property and your interests, as well as those of your contractor. For your protection, never sign a blank or incomplete estimate, or a contract or document you don’t completely understand.

    When signing the contract, don’t be afraid to write in special requests or verbal agreements you’ve made with your Contra Costa County molding and trim installer. This will protect you and ensure you get the services and details you are expecting. You may also add in expected end dates and any special instructions, provided you and your house trim contractor have discussed and agreed upon them.

    Furthermore, you may want to proactively protect your property. Before the work begins, schedule a walk through with the moulding and trim installation supervisor and conduct an inspection of your home. Discuss ways your moulding and trim contractor plans to protect your home interior and/or exterior and all areas that will be impacted by the work. You may also want to discuss details such as parking, storage, whether you can be in the home during installation, and finishing details.

    When you’ve reached an agreement, both you and your chosen Contra Costa County trim contractor should sign and date the document. When the work is done, do a final inspection together and verify that your expectations were met.

    Helping Your Decorative Moulding and Trim Installation Go Smoothly

    Regardless of what type of work you’re having done or the scope of the job, there are a few things you can do to prepare for the contractors’ arrival and while the work is in progress to help the decorative trim installation services go more smoothly. You may even lower the cost of the job and the possibility of damage to your home and belongings by taking a little time before the work begins.

    Ask about storage needs. Some Contra Costa County trim contractors will prefer to store and finish the trim in their office or workshop, but others prefer to keep the materials at your home. Many trim installers also agree that storing trim and crown moulding in the home where it will be installed for at least 24 hours before installation can help limit material shrinkage and cracking. Talk to your moulding company and find out if they want to store and/or finish the new trim at your location, how much space you’ll need, and how long they plan to need your location to double as storage.

    Remove furniture and unnecessary items from the rooms where the new moulding and trim is being installed. Before the work begins, move furniture toward the center of the room (or remove it from the rooms altogether, if possible) and remove artwork and décor from the walls. This will give your contractors more room to work and limit accidental damage. You may also want to store any heirlooms or expensive items that are in high-traffic areas of your home to prevent them from being accidentally broken or damaged.

    Provide adequate clearance and parking space for work trucks. Some trim and molding installation companies have large work trucks that require more clearance or parking space than average vehicles. Contact your contractor before the scheduled start date and ask them how many work vehicles will need parking space and whether the vehicles are oversized. You may find it helpful to walk through the site with your contractor ahead of time so they can point out any potential clearance issues or possible hazards before the work begins.

    Keep children and pets away from the work areas. Your contractors will be focused on installing and finishing your new moulding and trim, and they shouldn’t have to watch out for children and pets while they work. Leave the premises during the work, if possible, and keep pets locked away or at a different location for their safety and that of the workers.

    Be a Good Decorative Trim and Crown Moulding Company Customer

    Here are a few simple steps you can take to be a good customer when hiring Contra Costa County crown moulding and trim installers in Pleasant Hill, Concord, Martinez, Richmond and Brentwood and beyond.

    • Be clear and upfront with the moulding and trim installers. Let them know what you want, the long-term outcome you’re expecting and specific ways the contractors can satisfy your expectations.
    • Remember, a smile helps create a good working relationship and relieve tension when disagreements arise.
    • Before you hire a moulding and trim installers in Contra Costa County, restate your expectations and goals, and reiterate to the moulding and trim contractors your understanding of the agreement. Most problems with local moulding and trim installers occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflict.
    • Ask your Contra Costa County moulding and trim company if you should call to check on the progress or if they will call you with updates.
    • Be sure your contractor has a phone number where they can reach you at all times while they’re installing your new moulding and trim. The work will move along more smoothly if your moulding and trim installers can reach you for any necessary updates, questions or work authorizations.
    • When your contractor contacts you, return calls promptly to keep the crown moulding and decorative trim installation on schedule.
    • Pay for the new moulding and trim promptly.

    How do you benefit by being a good customer?

Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship.

Check The Work
What to Do Once Contra Costa County Trim & Moulding Contractors Have Completed the Work

When the crown moulding and installation work is done, your Contra Costa County trim contractor should provide you with a written invoice for services rendered. This is your chance to look over the invoice and verify that all work was provided and done in a manner that fits the original contract and the final invoice.

You are wise to walk through the rooms where the new moulding and trim was installed, preferably with your contractor, and to check over each piece to make sure it lives up to your expectations.

This is best done before the contractor leaves your home, as it may be easier to have any repairs made or explanations given while the company is still on the premises. It is especially true if you hired a crown moulding or trim contractor in Pleasant Hill, Martinez, Concord, Richmond, Brentwood, Danville, Antioch, Walnut Creek, Pittsburg and San Ramon, Discovery Bay, Cowell, Clyde, Tara Hills, Orinda, Maltby, Lafayette, Knightsen, Hilltop Mall, El Sobrante, Los Medanos or out of your local area.

You may also want to ask follow-up questions, including about the care and maintenance of your new crown moulding and decorative trim.

The invoice from your moulding and trim installers company should include the following:

  • The moulding and trim installers contractor’s name, physical address and state license number.
  • A complete list of all work performed, including repairs or preparation work, crown moulding installation, trim installation and finish work.
  • An itemized list of all materials used.
  • The total cost for the moulding and trim installation services, including an itemized amount charged for labor.
  • A written explanation of any warranties or guarantees provided by the product manufacturers and the moulding and trim installers contractors.
Read moreRead less
Written Warranties
Protect Yourself with Written Guarantees on New Moulding and Trim Work

Written warranties are your key to protecting yourself against mistakes and mishaps during and after the installation of your moulding and trim.

The following items should be included in any written guarantee document:

  • The Contra Costa County moulding and trim installers contractor’s name, physical address and state license number.
  • A description of what exactly the warranty covers. This should include whether the contractor will repair or replace any faulty materials or workmanship.
  • Any exclusions must be explicitly stated.
  • Your responsibility in the case of a problem and what you need to do in order to redeem the warranty.
  • How long the warranty is valid, and whether it expires on a specific day or is prorated (meaning, the warranty coverage and amount owed for repair or replacement diminishes over time).
  • If the warranty coverage is transferable to the new owner if you sell the home or commercial building in which the work was done.
  • Any actions on your part that may invalidate the warranty.

Popular Types of Decorative Moulding & Trim in Contra Costa County

Each home and business has its own needs when it comes to moulding and trim installation. Existing homes may require new moulding that matches or complements materials already in the home, while new construction may call for a completely different installation method. Likewise, the materials used to create trim and moulding vary to provide a range of options to fit various customer and contractor needs.

Contra Costa County crown molding and trim installers, whether located in Concord, Richmond, Antioch, Walnut Creek and Pittsburg or other areas, will have recommendations on the best materials, installation techniques and other considerations for your job. To better prepare yourself for the work ahead, get to know some of the most popular options by reading through the information below.

Decorative Crown Moulding
Decorative crown moulding (also spelled molding) is often found surrounding the ceilings of Victorian and vintage homes. It may also be in newer homes to create detail and interest near the ceiling line. Decorative crown moulding may be scalloped, carved, thick or thin, and is frequently used to hide the line between the ceiling and walls. It may be used to cover flaws or cracks, and can add a richness and visual interest to rooms.

Decorative Trim Installation in Contra Costa County
Like decorative moulding, decorative trim is used to create visual interest and to cover flaws or joints between walls, ceilings, floors, windows and doors. Trim can be painted in an accent color or to match walls, windows or doors. It may be used as art rails, installed in decorative patterns on walls, as a decorative chair rail or above wainscoting, or along the floor.

New Custom Crown Moulding & Trim
Whether you’re living in an older home with existing moulding or trim you’d like to match or a new home that could benefit from custom touches, custom crown molding and trim may be the answer for you. Custom moulding and trim can add an upscale look to a home or business, including wide crown moulding or decorative trim.

Exterior Crown Moulding
Homes in Contra Costa County, especially those that are from the Victorian period, may require the installation of exterior crown moulding. This is moulding and trim applied to the outside of the home, usually for decorative purposes, but also to hide cracks or flaws in the exterior. Exterior molding and trim can be painted or stained to any color to coordinate with existing paint colors and to add a custom touch.

Interior Trim and Moulding
Most molding and trim is interior in nature, and applied to the inside of homes and buildings for visual appeal and to hide flaws and delineations between walls and other surfaces. Interior trim is usually found around windows and doors, and along the line between walls and ceilings and floors. Interior mouldings may also be found along cabinets (known as cabinet moulding or cabinet trim), along staircases, edging built-in cabinets and fireplaces, and other decorative areas.

Door Moulding
Door moulding is found around the openings of doorways. It usually surrounds the areas where the doors fit; however, some door molding encloses the entire doorway in spaces where there is no swinging door and only an opening. Door moulding often matches window moulding to give rooms a certain continuity.

Baseboard Trim & Moulding Installation
Baseboard and moulding that runs along the wall near the floor helps protect the walls from abuse and hides any gaps or flaws on the floor and wall where the two surfaces come together. Baseboard may be a thin line of quarter-round or other small piece of trim, or it may be a tall, custom panel of moulding that gives a custom look to the wall and rooms where it is featured.

Simple Moulding & Trim
Simple trim and moulding can be one thin strip of trim, sometimes known as quarter round, that adds a nice, simple finish to an area. It may be paired in a room with wider moulding and trim to give a custom look, or may be the only finish in a modern space.

Wood Moulding & Trim
Most interior trim and molding installed in Contra Costa County, including San Ramon, Danville, Brentwood, Martinez and Pleasant Hill and beyond, is made of wood. This is usually the best option, as it can be stained, painted or simply varnished to match a variety of finishes, furnishings and styles. Other types of trim and molding include MDF (medium density fiberboard), plastic, polyurethane/urethane, and Styrofoam. Ask your Contra Costa County trim and moulding contractor which material they’d recommend for your job.

Styrofoam Crown Moulding / Polyurethane Crown Moulding
New crown moulding and trim made of Styrofoam, polyurethane, urethane or plastic can make installation easier in old homes or buildings where walls, ceilings and floors are uneven. Flexible mouldings and trims bend slightly, making installation look perfect even though the surface they’re installed on may be damaged or slightly altered from age. The appeal of polyurethane, urethane and styrofoam moulding and trim is the fact that it’s flexible crown moulding that can be painted, stained or treated to look just like wood moulding and trim.

Decorative Moulding & Trim Brands Requested by Contra Costa County Homeowners
Moulding contractors have different preferences for the type of trim and moulding they use, and they can recommend the best brand and type for your home. Some of the most popular brands used in the Bay Area and beyond, including Contra Costa County and Pleasant Hill, Concord, Martinez, Richmond and Brentwood, include the following:

  • Moulding & Millwork by Sauder Industries
  • Elias Woodwork Moulding & Trim
  • Architectural Millwork
  • Beaux-Artes Mouldings & Accents

Q: Can I install new moulding or trim in my house myself?
A: That depends on your skill and the type of work you’re needing. Some homeowners with good carpentry or building skills may be able to perform simple moulding and trim installation.

Q: How much will new moulding and trim cost me?
A: Trim and moulding range in price depending on the material (hardwood, MDF or plastic), size (traditional or custom width), where it is to be installed and the finish (plain wood, stained or painted). You can plan to spend about six to eight dollars per linear foot for installed and finished crown moulding. That will vary depending on your job and contractor, however, so call your local trim and moulding contractor for specifics on your job. Remember, though, that adding new trim and moulding to your home is one of the most cost-effective ways to update the appearance and create value in your home, so the cost may be well worth the investment.

Q: Can I stack mouldings together for a custom moulding look?
A: Yes. You can create a custom moulding look for less by stacking standard moulding and trim together to create the effect of a single piece of custom moulding. Some customers even stack pieces of moulding and trim to create custom baseboards for less. These may be to match original moulding, trim or baseboards, or to create a custom look throughout a new or remodeled home.

Q: How do I choose crown moulding and trim?
A: American hardwood moulding and trim, including oak and maple, is some of the hardiest and most beautiful moulding and trim available. Customers choose it for window and door trim, baseboards and chair rails, and other areas that receive a lot of traffic. Customers that have a lower budget but who still want the look of an expensive hardwood may choose a less expensive wood and stain it using a cherry stain or other expensive hardwood stain. Talk with your moulding and trim contractor to find the best trim and moulding for your needs and budget.

Q: How tall should by wainscoting be?
A: Wainscoting, usually made of hardwood boards and beadboard, is traditionally the height of a chair rail—the rail that runs along the bottom third of the wall—or a plate rail—the rail that runs along the bottom two-thirds of the wall. To find the best place for your wainscoting, divide the height of your room by three and draw a line there. Adjust it according to where you find it most appealing.

Q: Can a trim and moulding contractor recreate a look I’ve seen in a magazine or online?
A: Absolutely. Good trim and moulding contractors can almost always recreate custom crown moulding or trim looks you find in print or online. Save the original and talk with a contractor about your specific project.

Q: Will my new crown mouldings shrink or separate?
A: Trim and crown mouldings that are made of MDF (medium density fiberboard) or wood will shrink a little over time. To prevent shrinking, ask your moulding and trim contractor to acclimate your trim in your home for at least 24 hours before installing them.

Q: Can I use trim or moulding to improve the look of my existing fireplace?
A: Yes. Homeowners often choose to update the appearance of a fireplace by adding hardwood moulding and trim around it and the mantel to create a new look. Moulding strips can create the illusion of raised paneling, while decorative medallions and ornamental pieces can upgrade a plain mantel or fire place face. Some homeowners choose to extend a fireplace mantel or surround by tying in built-in bookcases, seating or curio cabinets using new moulding or trim pieces.
