Know What You Want
Think About Your Requirements Before Calling Marin County Trim Installers

A successful new moulding and trim installation comes with careful research and wise 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.

  1. Do I want a Diamond Certified 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 I’d like to have made before the contractors start installing my 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 carry on 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 Marin 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
Meet with Marin County Moulding & Trim Contractors at Your Home

Before making your decision and hiring a decorative trim and crown moulding contractor in San Rafael, San Anselmo, Novato, Mill Valley and Larkspur and the rest of Marin County.

Have a list of questions so that you leave each in-person meeting with all of the knowledge you need to decide which local decorative trim and molding company is the best fit for your needs.

The 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 installation process take from start to finish?
  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?

    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 Dogtown, Greenbrae, Black Point, Nicasio, Santa Venetia, Stonson Beach, Dillon Beach, Almonte, Lagunitas, 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?

    10. What did you like best about this Marin County moulding and trim service?
    11. Was there anything that surprised you about this company or their work?

  • How To Work With
    Working with Marin County Decorative Moulding & Trim Contractors

    After conducting interviews and narrowing down your search to 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.

    Read and be sure you understand all the terms and limitations included in any contract you sign. Contracts are binding. So 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 Marin 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.

    You may also want to proactively protect your property by scheduling a walk through with the moulding and trim installation supervisor and conduct an inspection of your home before the work begins. 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 Marin 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.

    Tips for Smooth Decorative Moulding and Trim Installation
    Regardless of what type of work you're having cone 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 requirements. Some Marin 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 Customer
    Benefit By Being a Good Decorative Trim and Crown Moulding Installation Customer

    • Remember, a smile helps create a good working relationship and relieve tension when disagreements arise.

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 Marin County moulding and trim company if you should call to check on the progress or if they will call you with updates.

Check The Work
Review the Completed Trim & Moulding Contractors' Work

When the crown moulding and installation work is done, your Marin 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 San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax, Ross and Belvedere, San Marin, San Geronimo, Strawberry Point, Terra Linda, Woodacre, Bel Marin Keys, Forest Knolls, Lucas Valley, Inverness 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, including repairs or preparation work, crown moulding installation, trim installation and finish work.
  • An itemized list of all materials..
  • 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.

Written Warranties
Protect Yourself and Your New Moulding and Trim Work with Written Guarantees

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

  • The Marin 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.

Top 10 Requests
Types of Decorative Moulding & Trim Available in Marin County

Marin County crown molding and trim installers, whether located in San Rafael, San Anselmo, Novato, Mill Valley and Larkspur 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.

Custom Crown Moulding & Trim in Marin County
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 Marin 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 for Marin County Homes
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
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 Marin County, including Ross, Belvedere, Corte Madera, Tiburon, Sausalito and Fairfax 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 Marin County trim and moulding contractor which material they'd recommend for your job.

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
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.

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.

Good Moulding & Trim Brands
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 Marin County and Fairfax, Tiburon, San Rafael, San Anselmo, Novato, Mill Valley and Larkspur, include the following:

  • Kleer Trimboards
  • Chemcrest Architectural Trim Moulding
  • Custom Decorative Mouldings & Trim

Frequently Asked Questions
FAQ About Crown Moulding and Trim Installation

You probably have many questions about the crown moulding and decorative trim installation process, starting with how to choose an installer and the best product for your home. While every contractor has his or her own methods, some answers are universal or more common than others.

The following frequently asked questions and answers will give you some idea of what to expect when choosing a moulding and trim company and having new decorative trim and crown moulding installed in your home or business.

Consult the contractors you're considering hiring for specific questions pertaining to your job.

Q: Why choose Diamond Certified moulding and trim installers?
A: Diamond Certified helps you choose local moulding and trim installers with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only moulding and trim installers rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your new crown moulding and trim purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing among Diamond Certified moulding and trim installers.

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.
