Taro Martinez: Stair Man

By James Florence, Diamond Certified Resource Reporter

Taro Martinez used to be an auto mechanic, but when he got tired of that livelihood, he decided to take a step in a new direction. “After owning an automotive repair shop for several years, I needed a change in both career and scenery, so I moved from Los Angeles to Northern California,” he recounts. “Soon after my arrival, I was offered a job with a staircase builder. I’d never done any work like that—I doubt if I’d even cut a piece of wood in half before—but I decided to give it a try. Naturally, there was a steep learning curve in the beginning, but I stuck with it and found my way. In 2004, I struck out on my own as an independent staircase builder.”

Regarding the transition from automotive work to building staircases, Taro says he appreciates the improved character of customer interactions. “Nobody likes having their car worked on. It’s kind of like going to the dentist—something you only do because you have to. In contrast, staircases are often more of a luxury item, so clients come in with a completely different mindset—it’s something they actually want to do. When a customer is actually happy to see you and ecstatic at the end of the job, it makes for a really nice interaction.”

A resident of Concord, Taro spends his time outside of work on a variety of active pastimes. “I’ve been drag racing since I was 13 and I’m still active in that,” he details. “Besides the actual racing, I spend a lot of time working on my car between races. I also practice Brazilian jiu-jitsu, which I’ve been doing for many years.” When he’s not at the race track or martial arts studio, Taro likes relaxing at home. “I live on an acre of property in Concord and it’s very peaceful, so it’s nice to just hang out and enjoy the tranquility.”

In regard to a professional philosophy, Taro espouses the value of helping others. “My business supports a lot of charities, including children’s hospitals, food banks and animal shelters,” he says. “That’s very important to me. It upsets me to hear about some of the bad things that are going on in the world, so I’m grateful that there are organizations dedicated to helping those affected. Also, I believe you have to give in order to receive. Even when my business was really hurting back in 2008, I continued to give. I figured that even though I wasn’t doing very well, there were others who were doing far worse. I think if you’re generous toward others, it will come back to you in the long term.”

When asked what he would do if he were to retire tomorrow, Taro says he’d continue pursuing the activities he currently enjoys in his free time. “I would continue to do jiu-jitsu a few times a week and work on my car. I’d also probably travel. I enjoy driving, so maybe I’d take a road trip across the country.”

Know What You Want
Your New Stairway Needs Should Come First

When dealing with Contra Costa County stair builders, your needs and desires are paramount. That’s why it’s so important for you to have an idea of what you want in terms of services, materials, style, and more before contacting staircase companies for estimates or bids.

You may not know exactly what you want, and that’s okay. It’s common for homeowners and business owners to coordinate with contractors to come up with designs and materials based on the clients’ wishes and the contractors’ experience. However, having some examples and ideas in mind will help you better express your wishes and will improve your chances of getting the staircase and services you’ve been looking for.

Start by collecting some pictures of staircase styles, handrail styles, newel post and finial designs, materials, and finish work that you like. This will help you show your contractor your design aesthetic and allow them to weigh in on your choices in terms of cost, availability, feasibility, installation, and more.

You should also have a written list of wants and expectations, both in terms of the materials and products and customer service. Write down your ideas and questions, and keep a record of the answers you get from various stair contractors in Contra Costa County. That will help you decide which one is the best match for you and your project.

Sample questions to ask yourself include these:

1.     Do I want a Diamond Certified stairway contractor that is rated best in quality and backed by the Diamond Certified Performance Guarantee?

2.     What is the reason for having work done, and what do I want to have completed? (This may include stair repairs, new handrails, balcony or landing guardrails, new stair treads, custom staircase designs, staircase replacement, new construction staircase, newel post replacement, stair spindle repair or replacement, or other services.)

3.     What is my budget for my new stairs or stair repairs?

4.     What is my preferred timeline? Is there a date by which I need to have the repairs, replacement, or stairway construction completed?

5.     What personal and professional characteristics am I looking for in my Contra Costa County staircase contractor?

What To Ask In Person
Questions to Ask in In-Person Interviews with Contra Costa County Stair Contractors

After you’ve narrowed down your choices by interviewing local stair companies over the phone, it’s time to meet with your top choices in person. This usually happens at the location where the work will be done, and it’s your chance to ask more questions about your specific job and their process. It’s the Contra Costa County staircase contractors’ chance to see the work site in person and get more information from you.

After meeting the company representatives in person, you may want to ask for a bid or estimate on the job at hand.

As with the phone interviews, you may find it advantageous to take notes on your conversations and record each stair contractor’s answers, suggestions, and attitude about the project at hand. The following are some sample questions you may want to ask. Add to these any questions that are specific to your job and needs.

  1. How much time will the staircase repair, refinishing, design, or installation take?
  2. What is your approach to a project of this size? (This will help you know what to expect if you hire this company.)
  3. Will I be able to stay in my home while you’re working on my stairs? Or will I need to stay somewhere else for part or the entirety of the job?
  4. Who will be doing the actual work on my project? Will it be you, company employees, independent contractors, or subcontractors?
  5. Will you give me written proof that everyone on my property and working on my job is covered by liability and workers’ compensation insurance?
  6. Will this staircase installation or remodel add value to my home?
  7. Do you have any recent projects like mine that I can see, either in photographs or in person?
  8. If I live in Orinda, Knightsen, Alamo, Diablo, North Richmond, Walnut Heights, Hercules, El Sobrante or outside of your immediate service area, will you charge extra for travel fees?
  9. Do you have recent customer references I can call? (See the next section for more information about calling references.)
  10. Do guarantee your work? Will you put warranties in writing?
  11. How would I handle any future issues? Are you responsible for warranty work if there’s ever a problem with my staircase or stair railings?
  12. What can I do to make the remodeling and addition process easier?

  • What To Ask References
    Learn From the Experiences of Other Clients of Contra Costa County Stair Builders

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

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

    If you can’t find Diamond Certified stair contractors that serve your location, you’ll have to do some research on your own. Start by calling references provided by your chosen stair building company, whether they’re in Pleasant Hill, Martinez, Concord, Richmond, Brentwood, Danville, Antioch, Walnut Creek, Pittsburg and San Ramon or beyond.

    As you do this, keep in mind that references provided to you by companies are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. Instead, references given to customers from companies are often cherry-picked to include only customers that the contractors know are satisfied instead of randomly selected from all their customers.

    If you do call references on your own, ask for a list of the company’s most recent customers or those who have had similar stair construction or repair services to those you’re considering. This will help ensure that you get more honest and unbiased references who can address your questions.

    Here are some sample questions you may wish to ask:

    1. Were you satisfied with the work and customer services provided by _(Contra Costa County stair contractor name)_?
    2. What was the type and scope of job they did for you (custom stair design, stair tread repairs, staircase installation, spiral staircase, new home stairs, curved staircase, hardwood staircase, metal staircase installation, stair rail replacement, stair handrail repairs, etc.)
    3. Did the Contra Costa County stair company you hired complete the work on time and as promised?
    4. Did the contractor keep you up to date on the status of the stair repair or installation project?
    5. Were there unexpected costs? If so, what were they for and were they avoidable?
    6. If you live in a smaller town such as Orinda, Knightsen, Alamo, Diablo, North Richmond, Walnut Heights, Hercules, El Sobrante, did they charge extra to travel to your home?
    7. Did the Contra Costa County stair builders show up on time?
    8. Were you able to stay in your home while the work was ongoing?
    9. Did they clean up after the work was done?
    10. If you need stair repairs or new stairs or handrails in the future, would you hire this stair building contractor again?
    11. Would you recommend them to friends or family?
    12. Is there anything else I should know before I decide whether to hire this contractor?

  • Review Your Options
    What to Consider Before Signing an Agreement with Custom Stair Builders

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    Before deciding on the best stair contractors in Contra Costa County for you, it’s important to consider the following questions.

    1. Can the staircase builders you’ve interviewed meet your needs in terms of scheduling, design, construction, budget, and customer service preferences?
    2. Are the Contra Costa County stair contractors knowledgeable about the scope and details of the stair repairs or installation you’re considering? Can they tell you which designs and products best suit your needs and why (e.g., stair repairs, stair tread repairs, stair handrail repairs, guardrail installation, new stairs, custom stairs, wrought iron stairs, etc.)?
    3. Is the company sensitive to your budget? Can they offer various solutions and products that fit your resources? Most stair contractors will give you bids for good, better and best options that include choices of design, aesthetics, cost, and services.
    4. Do the stair building contractors in Contra Costa County offer written warranties that protect you and your property in the event of a product failure or construction/installation problem?

    Once you’ve reviewed your notes and the answers to the above questions, it should be clear which Contra Costa County stair contractor can best meet your needs. Once you’ve made your decision, it’s time to move forward by signing a contract and setting a date for service.

  • How To Work With
    Plan Ahead to Get the Best Results from Contra Costa County Stair Contractors

    You’ll be much more likely to get the service and results you want and expect from your staircase contractors if you take time to plan carefully and choose the best contractor available. Knowing the type and scope of project you want done and the qualifications and qualities you want from your contractor will help you stay on track when talking with Contra Costa County stair builders. It’s also important to know your intended and absolute limit when it comes to budget. Having samples, photos, ideas, and input will help you better express yourself as you choose a contractor and create a plan forward with them.

    While it may be tempting to call contractors and hurry through the selection process so you can get the work underway and completed sooner, rushing through your decision can lead to poor choices, blown budgets, and an outcome that doesn’t look like your hoped-for staircase.

    What To Do Once You’ve Found a Stair Construction Company That Meets Your Needs
    Once you’ve found the right contractor, you can feel secure moving forward by asking for a detailed estimate and contract (including line item charges, expected star and end dates, exact products and materials to be used, special requests, and other job details). You should also ask for any guarantees or warranties in writing at this time.

    Read through the estimate or contract and be sure you understand all terms and limitations before signing. Contracts are binding legal documents, so never sign a blank or incomplete estimate or contract or one that you don’t completely agree with.

    Once you’ve signed the contract, ask for a copy of the document so both you and your Contra Costa County stair contractors have one on hand. Then set a date for the work to begin and begin the process.

    Tips for Successfully Working with Custom Stair Builders in Contra Costa County
    Good stair contractors in Contra Costa County, including those serving clients in Danville, Antioch, San Ramon, Walnut Creek and Pittsburg and throughout the Greater Bay Area, should be seasoned professionals who are ready and able to handle almost anything that comes their way. However, there are some things you can do to help the job go more smoothly and to potentially save time and money.

    Find or make storage space if needed. Your contractor may have space in their shop to store materials as they arrive or they may need you to store materials on site. Talk with your contractor to learn if they’ll need you to provide storage space and, if so, how much space is needed and for what amount of time.

    Make room for work trucks. Construction vehicles may need special parking consideration. Ask your stair builder how many work vehicles will need parking space on which days, and whether trailers or other large vehicles will be on site.

    Do a site walkthrough with your contractor. Walk through your property with your Contra Costa County stair building contractor so they can see the entire site from driveway and entry to work site and storage space. Ask them to be on the lookout for possible clearance issues, parking problems, or other potential hazards that you can move or minimize before the work begins.

    Prepare for construction. Staircase construction is often a dusty job, and it can be stressful to have contractors and workers in your home. Talk with your contractor about steps you can take to prepare and dust-proof your home before the work begins, and find out if you can stay in your home or be home during the work. If not, make a plan for where you’ll stay during the work, and be ready to leave the premises before work starts.

    Move and store household goods near the stair construction zone. Remove furniture, decorations, rugs, and other objects from the staircase area and the path from the door or storage area to the stairs. This will protect belongings from dust and damage, and it will allow your staircase contractors to move freely and avoid injury or potential damage. Additionally, think about the high traffic areas of your home where workers may be walking or carrying construction materials and move or remove items from those areas to prevent damage and injury. Additionally, if there will be heavy construction activity, think about fragile items, antiques, breakables, or items on walls that may shift, fall, or be susceptible to damage even if they aren’t in the immediate construction area and move them temporarily to a safer location.

    Keep children and pets away from the area. Open stairwells, missing stairs, temporary removal of guardrails and handrails, and other stairway construction can be a hazard, particularly to kids and pets. For their safety, keep household pets and children out of the area while work is in progress. It’s also smart to keep everyone away from the area even when work has stopped for the day, as stairways under construction can be extremely dangerous.

  • Be a Good Customer
    How You Can Be a Good Contra Costa County Stair Company Client

    It’s your stair contractor’s responsibility to design, build, and install your custom staircase or to perform your stair repair using the best possible techniques and materials.

    But, perhaps surprisingly, you can also play a part in the success of your new stairs installation. Why would you want to be a good customer? Good stair contractors in Contra Costa County appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems may be more easily resolved.

    Here are a few simple steps you can take to be a good customer when hiring Contra Costa County stair builders in Pleasant Hill, Concord, Martinez, Richmond and Brentwood and beyond. In doing so, you may help the job go more smoothly and end with a better result.

    • Be clear and upfront with the stair builder. Let them know what you want from them, the outcome you’re expecting, and specific ways they can satisfy your expectations.
    • Remember to offer a friendly smile, confidence that the contractor will do their job, and a helpful attitude.
    • Before you hire a stair builder or stairway contractor in Contra Costa County, restate your expectations and goals and reiterate to the representative your understanding of the agreement. Most problems with local companies occur because of a breakdown in communication. By taking steps to be clear about your expectations and theirs, you can avoid most conflicts.
    • Ask your stair building contractor 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 planning, designing, building, and installing your staircase. The work will move along more smoothly if your stair construction company can reach you if they have questions or need your input.
    • Return calls promptly to keep the stair construction services on schedule.
    • Pay for the work promptly and as agreed upon in your contract.

Check The Work
Review the Invoice for Custom Stair Installation

At the close of the job, ask your stair builder to show you the completed work and talk with you about what they did. Find out about any care instructions for your new stairs or handrails, and compare the final invoice with the work that was done and with the original contract. This is the time to ask any questions you might have about work, fees, materials, or warranties.

The invoice from your Contra Costa County staircase builder or custom stair contractor should include the following:

·      The stair contractor’s name, physical address and state license number.

·      A complete list of all work performed.

·      An itemized list of all materials used.

·      The total cost for the services, including the itemized amount charged for labor.

·      A written explanation of any warranties or guarantees provided by the product manufacturers and the contractors.

Written Warranties
Get Warranties and Guarantees in Writing

Written guarantees and warranty documents protect you and your contractor. They should clearly state what’s under warranty, for how long, what will happen if the warranty needs to be used, and who will take care of the problem.

Not all stair contractors in Danville, Antioch, San Ramon, Walnut Creek and Pittsburg and the rest of Contra Costa County guarantee their work, but those that do should be proud to offer written warranties that include the following items:

  • The Contra Costa County stair builder’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 faulty materials or poor 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 (if 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 building in which the new staircase was installed or the repairs were done.
  • Any actions on your part that may invalidate the warranty.

Remember that a warranty is only as good as the company that provides it. That’s why it’s important to choose a reliable, trustworthy, solvent company that’s known for good work and good value. If a company fails or goes out of business, their warranty coverage is no longer good and you will be stuck without protection if something goes wrong. That’s why the savviest consumers choose companies based on value and quality rather than price alone.

Frequently Asked Questions
Frequently Asked Questions About Custom Staircases To Ask Stair Builders

Q: Do local stair contractors provide free estimates?
A: Most stair builders and staircase contractors will provide free estimates based on your needs, wants, and specifics of your job. Other stair builders offer estimates and will refund the cost of the estimate if you decide to hire their company, and still others will charge a fee for estimates to cover their costs. Talk with your preferred stair builder about their policy on estimates. One thing you should consider is that estimates—whether free or as part of billable hours—are only as good as the estimator and their methods. Most of the best stair companies will insist on coming to your home or business to see the job site, measure the area, talk with you about your preferred style and materials, and provide an in-person estimate. Estimates over the phone can be helpful in giving you a ballpark range of cost for your project, but they are rarely as reliable as in-person estimates and bids.

Q: At what phase of the project should I reach out to local stair companies?
A: Most stair case companies recommend getting them onboard as soon as you know you’re going to be undergoing a building project or remodeling, replacing, or repairing your stairs or staircase. Some local stair builders can provide design and implementation, while others can work from designs created by architects or other planners. It’s wise to research, interview, and hire a staircase contractor early in the process so they can be part of the entire job from beginning to end.

Q: Can staircase builders design and fabricate the stairs they’ll be installing?
A: That depends on the staircase building contractors you hire. Some are able and equipped to design and fabricate new stairs, steps, and entire staircases. Others can implement others’ designs (those created by an architect or designer). Likewise, depending on their abilities and skill set, some staircase builders can fabricate custom stairs, handrails, and entire staircases, while other companies use materials manufactured by others to build and install stairs and staircases. If a custom designed, hand-fabricated staircase is important to you, you’ll want to add those capabilities to your wish list and include it in the interview questions you ask while searching for the best staircase builder for your job.

Q: What materials can I choose from when planning my custom staircase?
A: New stairs, staircases, and stair handrailings are available in a wide variety of materials, including wood, hardwoods, metal, steel, wrought iron, stone, polymers, plexiglass, and more. Wood staircases are available in many kinds of wood, including oak, maple, cherry, Brazilian cherry, hickory, and more. Talk with your staircase contractor about the materials they have available and what they recommend for the style you desire and the current look of your home.

Q: How long will I have to wait for my new stairs?
A: Most good stair builders have a lead time of a few weeks to a few months. There aren’t many qualified staircase contractors, so those who have a good reputation in the community and do the best work may not be able to start your project immediately. You will also need to consider the project. If you are having custom stairs designed, built, and installed, it can take several weeks to months to complete the project from beginning to end. Likewise, if the staircase you’re having installed uses unique or hard-to-find materials, it may take longer for the materials to become available or to arrive once ordered. Talk with your stair builder about your specific project for a timeline based on their availability and your needs.

Q: Do custom staircase builders also provide staircase, step, and handrailing repairs?
A: Most staircase contractors also offer repairs for steps, stairs, handrailings, newel posts, balusters and more. Talk with your contractor about repairs you need now and whether they’ll be able to help you in the future should your new custom staircase need repairs or refinishing.

Q: Can I get a new stair railing even if I’m not replacing my current stairs?
A: Absolutely. Stair railings often need to be replaced long before steps and staircases, so it’s common to add a new stair railing to an existing set of stairs. New stair hand railings can change the look of stairs, add safety and ease of use, and have other perks. Some companies can also offer new stair treads, newel posts, hand rail posts, balusters and balustrades, guard rails, and other features to update or change the look of stair cases.

Q: Will I have to move out of my home while my stairs are being built or repaired?
A: That depends on you, your needs, and your home. Many stair contractors are able to build and repair stair cases, handrails, and other features while you are still in your home. As long as the job site isn’t hazardous and there is a way for you to access necessary rooms in your house, it probably won’t be necessary for you to move out of your home for the duration of the job. Good contractors may also have ways to remodel, repair, or replace the stairs in your home in sections so the entire staircase isn’t torn out all at once or for long periods of time. If you’re planning to have major repairs or rebuilding done on your staircase, talk with your contractor about whether you’ll be able to stay in your home during the work and see if there is a way for them to accommodate your needs safely and without sacrificing the quality or timelines sof the job.
