The Vance Gate Repair San Mateo Guarantee
When we say we stand behind our work, we mean it in writing. Every gate repair, motor replacement, and access-control job we complete in San Mateo comes with our 365-Day Done Right Promise: if anything we fixed isn’t right, we make it right. No argument, no fee, no expiration date within that full year. Since 2014, we’ve repaired and installed over 22,000 gates, and every single one left with a written price agreed before we started and a documented photo record when we finished. That’s not a marketing line. It’s how Adrian Vance built this company out of commercial access-control work, and it’s what every San Mateo homeowner gets on every visit.
What’s Covered
- Workmanship on every repair. If a weld cracks, a limit switch drifts, or a gate arm binds within 365 days of our service, we return and correct it at no charge.
- Parts we supply and install. We document the exact part number, manufacturer, and installation date in your job record, so there’s no question about what was used or when it went in.
- Cleanup and property respect. We leave the work area as we found it, concrete dust and metal shavings included, because a gate repair shouldn’t create a second mess for you to manage.
- On-time arrival with advance notice. You get the technician’s name and photo before dispatch, and we keep you updated if traffic on 101 or El Camino Real shifts our arrival window.
- Honest, upfront pricing under Haven Standard Clause 1. The flat price is written and handed to you before any work begins. No “call for a quote,” no surprise invoice at the end, no hidden charges for the photo documentation or the second look we took at your hinge alignment.
Our Satisfaction Promise

If you’re not satisfied with how your gate operates after we’ve completed the work, call us at (650) 293-9440. A live person answers 24 hours a day, seven days a week. No voicemail loop, no callback queue. We’ll schedule a return visit, review the photo record from the original job, and identify what needs adjustment. If the issue stems from our work, we correct it under the 365-Day Done Right Promise at no additional cost. If we find the problem is unrelated, we’ll explain what we’re seeing and give you a written price before doing anything further. We’ve handled gates in San Mateo that had been “repaired” four times by four different companies before the homeowner called us. Our goal is to be the last company you need to call for that gate.

AfterLicensed & Insured Backing
A guarantee is only as solid as the company behind it. Vance Gate Repair San Mateo is licensed and insured, with background-checked, uniformed technicians on every job. That paperwork matters when a 400-pound swing gate is involved, or when we’re running low-voltage wiring for an access-control system near your home’s electrical service. Insurance protects your property if something goes wrong. Licensing means we’ve met California’s requirements for contractors working on automated gate systems. Adrian Vance started this company in 2014 after years of commercial access-control work, where missing documentation or uninsured labor doesn’t pass inspection. We brought that same standard to residential gate service in San Mateo. The Haven Standard requires it, and we don’t consider a job complete until the written record and photo log are in your hands and filed in ours.
How Our Guarantee Compares to Typical Gate Service in San Mateo

Most gate repair companies in the Bay Area offer a 30- or 90-day workmanship warranty. Some offer none at all, hiding behind manufacturer parts warranties that don’t cover the labor to replace a failed component. We think that’s thin protection for a gate that cycles two to four times daily, exposed to San Mateo’s salt air from the Bay and the temperature swings between foggy mornings and warm afternoons.
Our 365-Day Done Right Promise covers both labor and the parts we install. It also covers the documentation: under Haven Standard Clause 4 (Evidence on every job), every visit includes a photographed record of what we found, what we adjusted, and what we replaced. You get a copy; we keep a copy. If a question arises six months later, we both have the same evidence to work from.
We also offer something rare in this trade: a free second opinion on any written estimate from another company. Bring the paperwork to us. We’ll review it at no cost and tell you whether the scope, parts, and pricing look appropriate for your gate’s condition. No pressure to hire us. It’s a check on an industry where we’ve seen $3,200 quotes for a $650 limit-switch adjustment because the homeowner didn’t know what to ask.
What “Make It Right” Actually Means
Here’s how the 365-Day Done Right Promise works in practice. A homeowner in the Baywood neighborhood called us eight months after we replaced a swing-gate operator arm. The gate had started reversing halfway through its open cycle. We pulled the job record, reviewed the photos from the original installation, and found the limit switch had been set correctly but the gate’s hinge pin had developed play, throwing off the travel arc. We reset the limits, photographed the new position, and tightened the hinge. No charge. The issue wasn’t strictly our original work, but it affected the function of what we’d installed, and the homeowner had relied on our assessment. That’s the standard Adrian Vance set in 2014, and it’s the standard we apply across San Mateo.
Documentation as Guarantee

Every Vance Gate Repair San Mateo job leaves with two documents: the written price you approved before work started, and the photo log of what was done. This isn’t extra paperwork. It’s the proof behind our promise. If you sell your home, those records transfer to the new owner. If you need warranty service from a manufacturer like LiftMaster or FAAC, our documentation satisfies their claims requirements. If we need to return under the 365-Day Done Right Promise, we’re not guessing at what happened last time. We know, because we photographed it.
That documentation habit came from Adrian Vance’s commercial access-control background, where a site without wiring diagrams and as-built photos doesn’t pass final inspection. We apply the same rigor to residential gates in San Mateo, whether it’s a single-family driveway in San Mateo Park or a multi-unit entry in Hillsdale.
Your Part of the Agreement
Our guarantee covers what we control: our workmanship, our parts selection, our documentation, and our response when you call. What we ask in return is simple. Keep the photo log and written price we provide. Call us at (650) 293-9440 as soon as you notice something off, rather than waiting for a small issue to become a larger one. And if another company has worked on the gate between our visits, let us know, so we can factor that into our assessment. The 365-Day Done Right Promise applies to our work, not to modifications or repairs done by others.
