When a garage door repair goes wrong, a Dallas homeowner doesn’t need a refund policy. They need the door fixed. Our guarantee begins with that basic understanding. Every repair we complete, whether it’s a spring replacement in Lakewood or a cable fix in Preston Hollow, carries a written 365-Day Done Right Promise. If the repair fails within a full year, we return and make it right at no charge. Not a pro-rated credit. Not a service fee to come look. We show up, diagnose, and correct the work under the terms you received in writing before we ever touched your door. That’s the standard Wade Mercer, Owner of Brock Garage Doors Dallas, holds every technician to.
The guarantee is not a verbal assurance that evaporates after the truck leaves. It’s printed. It has our name on it, the date, the work performed, and the one-year term. Homeowners in Dallas keep that piece of paper because they’ve been burned before by companies that promise everything until something fails. We’d rather hand you the terms up front and then spend the next year proving we meant them.
What’s Covered
- Workmanship on every repair. If our installation or fix fails within 365 days, we return at no charge. The labor is covered, full stop.
- Parts we install. We source components matched to your specific system, and we stand behind the parts we put in. If a part we supplied fails within the guarantee window, it’s handled under the same written promise.
- Cleanup after the job. The work area looks like we were never there except for the working door. No old springs, cable scraps, or grease smears left on your floor.
- On-time arrival. We give you a window, then we hit it. If something outside our control changes that, a live person calls you before the window closes.
- Written price before work starts. The number you approve is the number on the invoice. No surprise fees discovered after the panel is open.
- Background-checked technicians. Every tech who arrives at your Dallas home has passed a background check and wears a uniform, so you know exactly who you’re letting through the door.

Our Satisfaction Promise
Here’s the process if something isn’t right. Call us at (254) 269-5837. A live person answers, day or night, weekends included. You’ll describe what’s wrong, and we’ll schedule a return visit. That second visit is free. It’s not a fee item and it’s not a negotiation. It’s part of every job we do.
If the repair failed because we made an error, we fix it under the 365-Day Done Right Promise at no charge. If the problem is something new, or something outside the original repair scope, we’ll show you exactly what’s happening, give you a written price, and you decide how to proceed. No pressure. No obligation.
Wade Mercer, Owner, has built this process around a simple idea: the only thing worse than a broken garage door is a broken garage door that was supposed to be fixed. So when we don’t get it right the first time, the follow-up is on us. We’d rather earn a customer for life than win an argument about a service charge.
Every job also honors the free second visit policy that’s baked into how we operate. You won’t have to ask for it, and you won’t have to fight for it. It’s simply what we do.
Licensed & Insured Backing
Licensing and insurance are the parts of a guarantee most homeowners never see until something goes wrong, and by then the cheap bid doesn’t matter anymore. We carry the licensing and insurance that a legitimate, accountable garage door company in Dallas should carry. It means there’s a structure behind the work, not just a person with a truck and a wrench. It means a homeowner has real recourse if a mistake happens. It means the business you hired can’t simply vanish into a different phone number next week.
This is the quiet part of the promise that supports the loud part. The 365-Day Done Right Promise means something because the company behind it is real, licensed, insured, and accountable to the codes and standards Dallas requires. Wade Mercer and the team at Brock Garage Doors Dallas stand behind every repair with both paperwork and presence.

AfterHow The Garrison Standard Shapes Our Guarantee
Brock Garage Doors Dallas is an independently owned and operated location within the Garrison Partners network. That means we’re a local Dallas business with the backing of a national standard that has been operating since 2001. The Garrison Standard governs how jobs are run: arrival windows that are actually kept, written pricing delivered before any work starts, a clean site when the truck leaves, and the one-year guarantee on every repair. The Garrison Code is the discipline behind the promise.
When a technician from Brock Garage Doors Dallas walks through your door, they’re not freelancing a repair style. They’re working to a system with two decades of refinement behind it. For a homeowner in Dallas, that means the consistency doesn’t depend on which tech arrives or what time of night it is. The same rules apply at 2 p.m. on a Tuesday in Richardson as they do at 2 a.m. on a Sunday in Oak Cliff.
Why Our Guarantee Matters for Dallas Homeowners
Garage doors in Dallas take a beating. The heat of July and August stresses torsion springs, the spring thunderstorms bring humidity that corrodes cables, and the clay soil shifting under slabs can knock tracks out of alignment years after installation. It’s not unusual for a spring to snap in September after a long, hot summer, leaving a car trapped and a schedule scrambled.
In that moment, the last thing you need is a repair company that treats the warranty as an afterthought. You need the fix, and you need to know it’ll hold. Our guarantee exists for exactly that scenario. We fix the spring, we hand you written terms covering the work for 365 days, and we answer the phone if anything goes wrong before those 365 days are up.
We also carry the brand training to back up the guarantee. Our technicians work on LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor systems. That matters because a Warranty that covers the labor means little if the tech misdiagnoses the system and installs the wrong approach. The right fix, applied to your specific door, is what allows the guarantee to actually work in practice.
Our 365-Day Done Right Promise in Writing
Let’s state it plainly. Your repair is covered in writing for 365 days. If it fails in that window, we return at no charge. The promise is handed to you before any work begins, along with the written price. The number on the invoice matches the number you approved, every time.
No fine print about “normal wear and tear” that excludes everything. No requirement to send photos and wait two weeks. A call to (254) 269-5837 gets a live person, and we schedule the return visit. We’d rather fix it a second time for free than leave a Dallas homeowner wondering if they made the wrong choice.
That’s the guarantee. We’ve been standing behind it in Dallas for years, and Wade Mercer, Owner at Brock Garage Doors Dallas, puts his name on it every time.
Frequently Asked Questions About Our Guarantee

No. You receive a written price before any work starts, and that’s the number you’ll see on the invoice. If the technician finds something else while working, they’ll stop and give you a new written price for the additional scope. You approve every dollar before it’s spent. Call us for an exact quote, estimates are free.
The second visit is free if the repair fails within the 365-day window. It’s part of every job, written into how we work, not a fee item or a negotiation point. If the problem turns out to be new and unrelated, we’ll show you what’s happening and give you a written price before proceeding.
Both. If a part we supplied and installed fails within the guarantee window, it’s handled under the same written 365-Day Done Right Promise. We don’t split hairs between labor and parts, we just make the door work again.
Call us. We’ll come back and assess it. If something is genuinely wrong, it’s covered. If we can improve the outcome, we will. You’ll never be charged for a second visit within the guarantee window. Call (254) 269-5837 and a live person will sort it out with you.
