Diamond Certified Researched Articles on Contra Costa Door

researched article

A Contra Costa Door technician works on a client's garage door.

Contra Costa Door installs, repairs, and maintains all types of garage doors for residential, commercial, and industrial clients in Contra Costa, Alameda, Solano, and Napa Counties. The company has the training and equipment to handle everything from broken springs and damaged panels to complete garage door replacements, and it’s also qualified to work on automatic gates, access control systems, and more.

Owner Dale Brooks says Contra Costa Door’s customer-oriented business practices have been vital to its seven-plus decades of success. “When someone buys a door from us, the relationship is just starting. It’s all about integrity for us—our clients know that if they ever need something serviced or fixed, we’ll be there for them.”

Contra Costa Door’s highly trained technicians utilize their expertise to guide clients toward the right garage door solutions for their homes and businesses. “Our technicians use professional installation methods and high-quality products to ensure the best possible results,” affirms Mr. Brooks. “By taking the time to understand each customer’s needs, they’re able to offer effective, budget-friendly solutions to their problems.”

“Customer service is our number one focus. We want our clients to be convinced that they made the right choice and are working with professionals who truly care about their long-term satisfaction. We’re not interested in doing a deal and then moving on—we want to build relationships with people who value our services and feel comfortable referring us to others.”

Perform simple safety and maintenance tests to maximize the efficiency of your garage door.
Like most mechanical devices, your garage door and its operating system need to be properly adjusted and regularly maintained in order to function correctly. Some tasks are best left to trained service professionals (spring repair and replacement, track/roller repair and replacement, door installation), but there are several basic maintenance tasks you can perform yourself.

Monthly visual inspection
Stand inside your garage with the door closed. Look over the garage door’s springs, cables, rollers, pulleys and mounting hardware (such as hinges) for signs of wear, damage or fraying. Is the mounting hardware loose? If something doesn’t look or sound right, it could be the symptom of a more serious issue.

Monthly door balance test
If your door is equipped with an automatic opener system, close the door and disconnect the automatic opener. Once you’re able to lift the door manually, it should lift smoothly with little resistance and remain fully open. If it’s difficult to open or doesn’t remain open, it may be out of balance and should be serviced by a professional.

Monthly reversing mechanism test
Garage door openers manufactured after January 1993 are required by federal law to be equipped with a reversing mechanism to prevent entrapment. If your system doesn’t have this feature, replace it with a new model. With the garage door fully open, lay a piece of wood on the floor in the center of the opening where the door would touch the floor. Push your garage door opener’s transmitter (wall button) to close the door. When the door strikes the wood, it should automatically reverse. If it doesn’t, call a service technician.

Monthly photo eye test
Garage door openers manufactured after January 1993 are required by federal law to be equipped with a photo eye or edge sensor to prevent entrapment. If your system doesn’t have this feature, replace it with a new model. With the garage door fully open, push your garage door opener’s transmitter to close the door. Wave a long object in front of one of the door’s photo eyes so it “breaks the beam.” The door should reverse and reopen. If it doesn’t, pull the object out of the door’s path and let it close. With the door in the closed position, clean the photo eyes with a soft, dry cloth. Gently adjust the photo eyes by hand if they appear to be out of alignment. Open the door and repeat the test. If the door doesn’t reverse and reopen, call a service technician.

Few garage door companies have been able to earn Diamond Certified, which means they’ve been independently rated Highest in Quality and Helpful Expertise. Even fewer can also claim more than seven decades of industry experience, but that’s exactly the case for Contra Costa Door. “My father founded this company in 1953, and when I joined him, my vision was to take us to the next level and find ways to serve our customers more effectively and efficiently,” explains owner Dale Brooks. “That included opening a showroom so people could see what they were buying and actually meet the technicians who would be working on their projects.”

Contra Costa Door installs and repairs all types of garage doors for residential, commercial, and industrial clients in Contra Costa, Alameda, Napa, and Solano Counties. The company has the in-house capabilities to handle everything from broken springs to complete garage door replacements, and it’s also qualified to work on automatic gates and access control systems.

Unlike less experienced garage door companies that take a “one and done” approach to each project in an effort to maximize their workload volume, Contra Costa Door focuses on building long-term relationships with its clients. “Our customers know that if they ever need something fixed or serviced, we’ll be here for them,” affirms Mr. Brooks. “The garage door is often the largest moving part of the home, so it’s important to work with a company that you know and trust. We want every customer to be convinced that they made the right choice.”

Ultimately, Mr. Brooks says most of Contra Costa Door’s success can be attributed to its skilled installers and repair professionals. “Our technicians are qualified professionals who have been working with us for a long time, so our clients know what to expect when they arrive. They’re true tradespeople who have many years of experience and know how to do every aspect of the job while maintaining high levels of customer satisfaction.”

Dale Brooks: Making the Years Count


By Matt Solis, Editor



As the son of a garage door professional, Dale Brooks didn’t need to look far when he started considering his own career pathway. “My dad founded Contra Costa Door in 1953 and I used to tag along with him while he worked,” he remembers. “I ended up going to college for aeronautical engineering and economics, but I got appendicitis right after I graduated and was laid up for a while. My dad asked me, ‘Have you ever thought of doing anything with this bu...
