Every repair we make in Alpharetta comes with a promise that’s printed, signed, and handed to you before our truck leaves your driveway. It’s called the 365-Day Done Right Promise, and it means exactly what it says: if the repair fails within a full year, we come back and fix it at no charge. No phone tag, no fine print, no “that part isn’t covered.” We put the guarantee in writing on every job because a handshake is nice, but a document holds up better when something goes wrong at 7 a.m. on a Monday. That’s the standard Wade Mercer runs this business on, and it applies to every garage door repair, opener repair, and cable repair we perform.
What’s Covered
- Workmanship on every repair. If our fix doesn’t hold, the 365-Day Done Right Promise brings us back to your door at no cost, confirmed in writing before we start.
- Parts we install. When a component we supplied fails inside the guarantee window, the replacement part and the labor to install it are on us.
- Honest pricing, locked in writing. You approve a written price before any work begins, and the invoice matches that number, every time, with no surprise line items.
- Clean job site. We don’t leave springs, cable scraps, or grease smears on your garage floor, and we haul off old parts when the job’s done.
- On-time arrival. When we give you a window, we show up inside it, and if something beyond our control delays us, you hear from us before the window closes.
- Background-checked technicians. The uniformed tech at your door has already passed a background check, so you know who’s walking into your garage.

Our Satisfaction Promise
If you’re not satisfied with a repair we’ve made, here’s exactly what happens: you call (229) 404-6747, a live person answers, and we schedule a return visit. There’s no charge for that second trip. Not a dispatch fee, not a labor minimum, not a “diagnostic” charge. It’s part of the job. Wade Mercer and the team at Brock Garage Doors Alpharetta don’t believe a repair is finished until you say it works the way it should, and if that takes a second visit, that’s our problem to solve, not your bill to pay. We’ll walk through what went wrong, show you what we’re fixing, and make it right under the same written guarantee. If we made the mistake, we own it. If a part failed early, we replace it. You’re never left holding a repair that didn’t stick.
Licensed & Insured Backing
Anyone can print a guarantee that sounds good on a website. The question is whether the company behind it will still be around when you need to enforce it. Brock Garage Doors Alpharetta is licensed and insured, and we operate as an independently owned location within the Garrison Partners network, a structure that’s been in place since 2001. That means your repair is backed by a local business you can hold accountable and a national standard that demands documentation, verified technicians, and written commitments on every job. Insurance protects your home and our crew while work is underway. The license means we answer to state requirements. The guarantee means we answer to you.

AfterWhy We Put It in Writing
A verbal promise evaporates the moment the truck pulls away. That’s not an opinion. It’s what happens when there’s no record. So every job we do in Alpharetta comes with two written documents: the price you approved before we started, and the 365-day guarantee that covers what happens after we leave. Both are yours to keep. The guarantee document states the repair performed, the date, and the terms of the Done Right Promise in plain language. If you ever need to use it, you’re not relying on someone’s memory of a phone call. You’re holding our commitment in your hand, signed by the company that made it. That’s how the Garrison Standard runs, and it’s how Wade Mercer runs this shop.
What the Guarantee Does Not Cover
Let’s be straight about this, because a guarantee that hides its limits isn’t worth the paper it’s printed on. Our 365-Day Done Right Promise covers the workmanship and parts from a repair we performed. It does not cover new damage from a car bumping the door, a tree limb hitting the track, or someone attempting a DIY adjustment after we leave. It doesn’t cover normal wear on components we didn’t touch. And it doesn’t extend the manufacturer’s warranty on your opener or door, which is a separate document that varies by brand and model. What it covers is the thing you hired us for: the repair we made. If that repair fails, we fix it. That’s the whole promise, and it’s a good one.
How a Claim Works
Call (229) 404-6747 and tell the person who answers that you need a return visit under the Done Right Promise. We’ll pull up your job record, confirm the repair date and what was done, and schedule a tech to come out. Bring the written guarantee with you to the appointment, though we keep our own copy. The tech inspects the repair, identifies what failed, and corrects it at no charge. There’s no claim form, no deductible, and no waiting period. A real person answers when you call, 24 hours a day, every day. If the garage door cable we replaced snaps again in month eleven, that’s covered. If the opener repair we made stops responding in week two, that’s covered. We show up and we fix it. That’s the deal, and it’s been the deal since day one.
Questions Homeowners Ask About the Guarantee
Is the guarantee really free?
Yes. The 365-Day Done Right Promise is included with every repair at no additional cost. It’s not an upsell, not a protection plan, and not a subscription. You get it because we’d rather guarantee our work than argue about it later. Call (229) 404-6747 if you want us to walk you through the exact terms before you book.
What if the repair fails after a year?
After the 365-day window closes, a follow-up repair is a new job with a new written price, which you approve before work begins. But here’s what our experience in Alpharetta shows: a repair that holds for a full year typically holds for the life of the component. Most failures that happen occur early, and those are the ones the guarantee catches. Call (229) 404-6747 and we’ll give you an honest take on whether a follow-up is worth doing.
Will the price change once you see the repair?
No. The price we put in writing is the price you pay, and we don’t amend it after the fact. If we discover something unexpected during the repair, we stop, show you the issue, and give you a new written price before touching it. You’re never surprised by an invoice. That’s a rule, not a courtesy, and it applies to every job in Alpharetta.
