Gary Robertson: A Lifelong Builder

By James Florence, Diamond Certified Resource Reporter

WALNUT CREEK — Reflecting on a career that spans more than four decades, Gary Robertson says his beginnings as a builder go all the way back to childhood. “My grandfather was a builder in Canada, and when we visited, he would have me work with him on different projects,” he remembers. “During my teen years, I would work during the summer for various contractors doing things like painting and repairs. In 1976, I moved from my home state of Massachusetts to Northern California, where I started a small handyman business. Over the next few years, I got my painting and general contractor licenses and continued to grow my business into a full-scale remodeling firm.”

Today, as owner of Robertson Renovations, Gary says his favorite part of his job is turning each client’s vision into reality. “I enjoy interacting with customers, finding out their desires for their projects and seeing their reactions when we deliver the results.”

A resident of Santa Cruz (where he lives with his partner, Heidi), Gary spends his time outside of work on a variety of active pastimes. “I’m an avid surfer, though I haven’t been doing much of that lately due to an ACL injury,” he details. “I also enjoy mountain biking and woodworking. Heidi’s and my biggest hobby is gardening—we grow all types of fruits, vegetables and flowers. Heidi is a retired teacher, and each year she donates several plants to local schools for their fundraiser auctions.”

In regard to his life and career, Gary espouses the importance of being fully invested. “I live life to the fullest, and that’s also how I approach my business,” he explains. “My crew and I always give 100 percent to whatever we’re doing. As far as the day to day, I try to be appreciative of what I have, give whenever I can and be present in whatever I’m doing.”

When asked the first thing he’d do if he were to retire tomorrow, Gary says he’d relocate to a tropical locale. “I’d move to the big island in Hawaii and continue to garden, but with more tropical plants. We actually had a property in Hawaii we were going to build on, but we lost it to a volcano. It’s now under 90 feet of lava, so we’re currently looking at other possible locations. Worst-case scenario, I may just stay here in Santa Cruz. Our current home is only six blocks from the beach, so that’s not bad.”

Ask Me Anything!

Q: What’s your favorite Bay Area restaurant?

A: The French Laundry in Yountville.

Q: If you could go surfing anywhere in the world, where would you go?

A: New Zealand. There’s a coastal town called Raglan that has really nice waves.

Q: Are you an early bird or a night owl?

A: An early bird.

Q: What’s your favorite thing to do on a rainy day?

A: Sometimes, Heidi and I will go for a walk in the rain. Other times, we’ll stay inside, relax and do a puzzle.

Q: If you could time travel, would you go to the past or the future?

A: Neither—I’m happy right here in the present.

  • What To Ask References
    What to Ask Previous Customers of a Contra Costa County Design & Build Contractor

    It’s best to choose a Diamond Certified design & build contractor because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality contractor work 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 design & build contractor within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your design & build contractor.  Keep in mind, though, that references provided to you by the design & build contractor 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 cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

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

    1. Were you satisfied with the service from the (design & build contractor name)?
    2. What type of design & build project did you hire the general contractor to complete?
    3. Would you recommend this design & build contractor to your family and friends?
    4. Did they finish the job on time?
    5. Did the general contractor clean up after completing the job?
    6. Do you feel like the general contractor charged a fair price for the quality of the work?
    7. Did the contractor seem receptive to your input?
    8. Did the design & build contractor show up on time?
    9. If you need a design & build contractor in the future, will you consider hiring this general contractor?
    10. Did the contractor provide answers to questions to your satisfaction?
    11. Were there any unexpected costs? If so, what?

  • How To Work With
    Hiring a Design-Build Contractor in Contra Costa County That You Trust

    Once you’ve hired a design-build company in Contra Costa County, including the smaller cities of Point Richmond, Los Medanos, Moraga, Orinda, Byron, Clyde, and Discovery Bay, you will have an initial meeting between you and the contractor to discuss your requirements and the contractor’s qualifications. An estimate of the projects and its feasibility is drawn out. Furthermore, you will discuss the budget and design of the project as well as any restrictions and permissions that will be needed. The contractor will provide you with an estimate based on the design specifications. He will also offer choices in terms of designs and construction. Once the final contract has been drawn, the next step will be applying for permission. Last of all, the construction and financing process will begin.

    Be Contract Specific
    Once the contract is drawn up, it should be signed by both parties: you, the project owner, and the contractor. If any sub-contractors will be involved, they should sign the contract as well. The contract should protect the interests of both you and the contractor. As a result, it should include the following:

    • A clear, concise, and complete description of the project, including start and completion dates. It should also include who will be responsible for each aspect of the project.
    • Contractor’s name, physical address, mailing address and phone.
    • Quote of the project.
    • Terms of payment schedule as well as the payment schedule for the contractor, subcontractor(s) and suppliers.
    • Who will be responsible for obtaining necessary permits (this is usually the contractor).
    • Warranties should be written and the length of time as well as limitations should be covered. Warranties should cover materials and workmanship, and names and addresses of the warrantor. This may include the contractor, manufacturer, and distributor.
    • Detailed materials list: product, size, color, type, model, and brand name. Any additional or alternate materials that may be used if necessary should also be listed.
    • How “change orders” will be handled. Any changes or additions to the project should be written up in the contract so that the conditions for change are pre-determined. Furthermore, the contract should list how and when payment will be made for adjustments. Because change orders are common aspects of most remodeling jobs, it is common for remodelers to require payment before the work actually begins.
    • Any oral promises made.

    Take Precautions to Protect Yourself
    Taking precautions will help protect you and your home project investment. It will also increase your chances of success. Consider the following guidelines:

    • Agree to make payments as the project progresses, contingent upon completion of a determined amount of work. This way, if work on the project is delayed, payment will be delayed as well.
    • Do not make final payment until the work completed meets agreed upon specifications, building code requirements, and that subcontractors and suppliers have all been paid.
    • Do not sign a contract or any document until you have thoroughly read through it and filled in any blank spaces.
    • Do not sign a contract that uses vague terms. Make sure that all terms are specific regarding project requirements and the work that will be performed.
    • Don’t agree to finance your project through your contractor. Shop around for better loan terms.
    • Before deeding your property, be sure to first consult an attorney or knowledgeable friend or family member.

  • Be a Good Customer
    Being a Good Contra Costa County Design & Build Contractor Customer

    It’s the design & build contractor’s responsibility to complete a successful design & build project for you according to your specifications. But you play a big part in the success of your design & build contractor, too. Here are a few simple steps you can take to be a good customer when hiring a Contra Costa County design & build contractor.

    • Be clear and upfront with the design & build contractor. Let them know what you want from your design & build contractor, the long-term outcome you’re expecting and specific ways they can satisfy your expectations.
    • Remember, a friendly smile goes a long way!
    • Ask your design & build contractor if you should call to check on the progress or if he will call you with updates.
    • Be sure your design & build contractor has a phone number where they can reach you at all times while they’re completing your design and build project. The work will move along more smoothly if your design & build contractor can reach you for any necessary updates, questions or work authorizations.
    • When your design & build contractor contacts you, return calls promptly to keep the design & build contract work on schedule.
    • Pay for the design & build contractor’s work promptly.
    • Before you hire a design & build contractor in Contra Costa County, including the larger cities of San Ramon, Danville, Brentwood, Martinez, and Pleasant Hill, restate your expectations and goals, and reiterate to the design & build contractor your understanding of the agreement. Most problems with local design & build contractors occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.

    Why would you want to be a good customer? Design & build 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.

Frequently Asked Questions
FAQ for Local Design/Build Contracting Companies

Q: Why choose a Diamond Certified design and build contractor?
A: Diamond Certified helps you choose a design and build contractor with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only design and build contractors 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 purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified design and build contractor.

Q: What are the advantages of a design/build project?
A: There are several advantages to a design/build project that include sole source responsibility; it’s a straight-forward approach to design with greater flexibility; better quality control; participation by the client in selection of materials; rapid response to changes in scope with minimal paperwork, and more.

Q: What are the design/build contractor’s responsibilities?
A: His responsibilities include quoting on work within his area of expertise; stating clearly in his proposal exactly what will be done, what is not included, what the price will be, and what the schedule will be; producing a functional system that actually functions completely to the satisfaction of you, the client.

Q: What are my responsibilities as a client?
A: The client’s responsibilities include treating the design/build proposal as confidential rather than shopping the proposal on the open market; checking references of those submitting proposals; and pay the hired contractor for the work done.

Q: Why doesn’t a design/build contractor sell design services alone?
A: It may represent a loss of alternate design/build business as it ties up a design staff. Furthermore, the typical design/build contractor does not carry liability insurance to cover his designs if they are installed by somebody else.

Q: Is it possible to use a specific design/build contractor yet retain competitive prices?
A: The answer is yes because typically contractors agree to provide a complete design and construct project on a “guaranteed maximum” basis. They will agree to charge a set amount for a project and no more, assuming the scope does not change. If the costs are less than originally estimated, savings are passed on to the client on a pre-agreed basis.

Q: How long will my construction project take to complete?
A: That depends on the job. When you meet with your contractor, they should be able to fairly accurately determine an estimated end date.

Q: Do design/build contractors operate a clean worksite?
A: It is a good idea to check the work of a design/build contractor before hiring to see if, in fact, they operate clean worksite. Check to see if they use floor protectors and put plastic sheets for dust containment. Note if there is a line item in the contract that includes jobsite setup, cleanup, and portable facilities.

Q: If I am a contractor, can I work with a design/build team on my project to reduce the cost?
A: Many design/build contractors are happy to work alongside their clients as long as they are qualified. However, sometimes lesser skilled, free labor can actually increase the overall cost of a project.

Q: How do I know that a design/build contractor is not marking up your credit allowances?
A: A quality design/build firm will have open and transparent paperwork. They should be able to show you receipts for what has been purchased, including contractor discounts.

Q: Can a design/build contractor give estimates over the phone?
A: That depends on the job. A simple job such as putting up a fence can generally be quoted regarding the price of various fencing materials. But more complex jobs will require an on-site inspection in order to quote an accurate estimate.

Q: Are estimates of design/build companies negotiable?
A: Generally they are not. A quality design/build firm will give a fair estimate based on current market prices for your community. They may be able to work with you in lowering the overall cost by using different materials or coming up with a more efficient design.
