Frequently Asked Questions

We arrive in a marked vehicle, introduce ourselves by name, and inspect every moving part of your door system. That means testing spring tension with a calibrated gauge, checking cable wear, inspecting rollers and hinges, lubricating the torsion assembly, and testing the safety reverse and photo-eye alignment. We photograph anything that fails inspection and show you the images. You get a written report with our findings and a flat quote for anything we recommend. Under Clause 4 of the Haven Standard, you see the failed part photographed before anyone quotes a replacement.

Most repairs take 45 minutes to 2 hours. A standard torsion spring replacement on a 16-foot door in a Walnut Creek ranch home takes about an hour. Track realignment or roller replacement might run 90 minutes. Full door replacement is a half-day job: remove the old door, install new hardware, hang the new panels, balance the springs, and test everything. We give you a time estimate in writing with your quote, and we text when we're on the way so you're not waiting around.

Yes, estimates are always free and come with no obligation. For replacement doors, we measure your opening, check headroom and side clearance, note any structural issues, and show you sample panels and color chips from brands we carry. You'll get a written quote with model numbers, insulation values, and the total installed price. For repairs, we diagnose the issue and quote the fix at no charge. Call (510) 390-9102 to schedule.

We service sectional steel doors, wood composite doors, aluminum full-view doors, and the occasional one-piece tilt-up door still found in some 1960s Walnut Creek neighborhoods near Larkey Park. We work on standard torsion spring systems, extension spring setups, and high-lift or vertical-lift configurations for homes with lift-equipped garages. If we can't service it, we'll tell you honestly and point you toward a specialist.

Torsion springs are the heavy coils mounted above your door on a steel shaft; they twist to store energy and lift the door. Extension springs are the lighter springs mounted parallel to the horizontal tracks on each side; they stretch and contract. Torsion springs are safer, last longer (typically 10,000 to 20,000 cycles versus 5,000 to 10,000 for extension), and are what we install on nearly every Walnut Creek replacement. Extension springs are common on older or lighter doors and require safety cables because a broken spring can fly with dangerous force.

We primarily install Raynor and LiftMaster doors and openers, with Chamberlain smart openers available for customers who want advanced app control and camera integration. Raynor builds their doors in the Midwest and has a strong reputation for steel gauge consistency, which matters in Walnut Creek's climate where morning fog moisture can accelerate rust on thinner doors. LiftMaster and Chamberlain are both made by Chamberlain Group and dominate the professional installer market for good reason: parts availability, warranty support, and smart-home compatibility.

Yes, our service trucks stock torsion springs in common sizes for doors up to 18 feet wide, extension spring sets, cables, rollers, hinges, weatherstripping, photo-eye sensors, and LiftMaster and Chamberlain opener units. For Walnut Creek's mix of 1980s ranch homes and newer construction off Treat Boulevard, we carry the spring wire sizes and drum configurations we see most often. If your door uses an unusual spring or a discontinued Genie part, we may need to order it, but we'll tell you that upfront with a timeline.

We can repair many Genie openers, especially newer models with available parts. Common fixes include replacing the logic board, the travel module, or the safety sensor set. The founding story of Servo Garage Doors started with exactly this situation: a commercial door technician who was tired of watching residential companies sell a whole opener when a $40 logic board would have done it. That's now Clause 4 of the Haven Standard. We photograph the failed component, show it to you, and quote the repair before suggesting replacement. If your Genie is over 15 years old and parts are discontinued, we'll be straight about that too.

Belt-drive openers are quieter and worth the extra $80 to $150 if your garage is under a bedroom or living space, which is common in Walnut Creek's two-story homes off Oak Road and in the Buena Vista area. Chain-drive units are proven, durable, and slightly less expensive; they're fine for detached garages or when noise isn't a concern. We install both and will recommend based on your door weight, ceiling height, and how you use the space.

Every pro working under our name is required to hold the license and insurance their state requires, and we verify it before they ever represent Servo Garage Doors in Walnut Creek. You can ask to see the license number; it's also on your written estimate. We carry general liability and workers' compensation coverage. This isn't a handshake operation, and we don't send anyone to your home who isn't properly documented.

Permit requirements depend on the scope. A like-for-like door replacement on an existing frame typically doesn't require a permit in Walnut Creek. If we're modifying the opening, converting a window to a door, or doing structural work on the garage front, the city may require a permit. We know the Contra Costa County building department's requirements and will tell you during the estimate if your job needs permitting. If it does, we handle the paperwork or guide you through it.

No. Garage door torsion springs are under extreme tension, typically 100 to 200 pounds of torque, and a winding bar slip or broken spring can cause serious injury or death. The Contra Costa County area has seen emergency room visits from DIY spring repairs. We don't provide step-by-step instructions for spring replacement because the risk isn't worth any savings. What you can safely check: whether the door is properly balanced (it should stay put at waist height when disconnected from the opener), whether cables are frayed, and whether photo-eyes are aligned and clean. For anything involving springs, cables, or the torsion assembly, call a trained professional.

Yes, the phone is answered 24/7, and we dispatch for genuine emergencies like a door stuck open overnight, a spring that snapped with your car trapped inside, or a cable that came off the drum leaving the door crooked and unsafe. We don't promise a specific arrival window, but our local team lives and works in the Walnut Creek area and can typically respond to emergency calls faster than companies dispatching from Oakland or Richmond. Call (510) 390-9102 anytime; a live coordinator will connect you with the local team.

A door that won't close and leaves your home exposed, a broken spring with a vehicle trapped inside, a door that's come off the track and is hanging precariously, or an opener that failed on a door you can't lift manually. In Walnut Creek's hillside neighborhoods, a door stuck open during a rainstorm can also mean water intrusion and damage. If you're unsure whether it's urgent, call us and we'll help you assess. We'll never charge you just for asking.

We often can, especially for common repairs like spring replacement, cable repair, or opener troubleshooting. Same-day availability depends on call volume and parts needed. We carry standard springs and opener units on our trucks, which covers most Walnut Creek homes. If your door uses an unusual size or a discontinued part, we'll order it and schedule the repair as soon as it arrives, with a temporary secure-close if needed.

Our repair work carries a written warranty: one year on labor, and the manufacturer's warranty on parts, which is typically three to ten years depending on the component. Torsion springs we install are warrantied for 10,000 cycles minimum, which translates to roughly 7 to 10 years for a typical Walnut Creek household using the door 3 to 4 times daily. Your written invoice specifies the warranty term for each part and the labor coverage. That's part of Clause 1 of the Haven Standard: written price, written scope, written warranty, before anyone starts.

The Haven Standard is the five-clause code every Servo Garage Doors branch agrees to work under. H: Have it in writing, flat price, written scope, written warranty, before anyone starts. A: Arrive on schedule, with a real window, a named tech, and a text when they're on the way. V: Verified crews, licensed, insured, background-checked. E: Evidence on every job, photos and readings of what we actually found. N: No surprises, no door upsell, no scope creep, no "while we're in here." It was built from the founding rule that the customer sees the failed part, photographed, before anyone quotes a replacement.

Call us. If it's within the warranty period, we fix it at no charge. If it's outside warranty, we'll diagnose the issue honestly and quote a fair repair. We document every job with photos and notes, so we can reference what we found and what we did. That documentation protects both of us. We're not hard to reach, and we don't disappear after the invoice is paid. Our local reputation in Walnut Creek, Concord, and Danville depends on handling the follow-up right.
