Verify the license and insurance before anyone touches your door
In California, garage door installation and repair falls under the Contractors State License Board (CSLB), most often through the C-61/D-28 'Doors, Gates and Activating Devices' specialty classification. Before you schedule anything, ask for the company's license number and look it up on the CSLB website. It takes about a minute and tells you whether the license is active, who it actually belongs to, and whether the contractor carries workers' compensation coverage. A legitimate local pro will hand this information over without hesitation. Just as important is liability insurance: if a spring lets go or a panel gets dropped on your car, you want the company's policy covering it, not your homeowner's deductible. Be cautious with anyone who offers only a cell number, insists on cash, or gets defensive the moment you ask to see credentials.
Insist on a written, itemized estimate
A trustworthy company puts the price in writing before the work starts, broken down by part and labor rather than a single vague 'repair' figure. Ask what specific parts are being replaced, what each one costs, and what the labor charge is. Springs, rollers, cables, and openers are all separate line items, and lumping them together is exactly how surprise totals happen. Garage door pricing varies widely, so treat any quote as a range that depends on your door's size, spring type, and hardware. A spring replacement, for instance, typically lands somewhere in the low-to-mid hundreds depending on the spring, while a full door replacement can range from roughly a thousand dollars into several thousand depending on material and insulation. The point isn't the precise number. It's that an honest estimate can explain where that number comes from.
Judge them by how they communicate before the job
How a company talks to you before the work is a reliable preview of how it will behave once it's in your driveway. A dependable outfit gives you a clear arrival window, shows up in a marked vehicle, and explains what it found instead of just announcing a total. Look for a checkable presence: a consistent business name, a real local phone number, and a track record you can confirm through independent review platforms rather than testimonials posted only on the company's own site. Ask how long they've served San Bruno and the wider Peninsula, and whether they warranty both parts and labor. You aren't just buying one repair. You're choosing who you'll call the next time the door refuses to open on a cold, foggy morning.
