Call (254) 269-5837 to claim any current offer from Brock Garage Doors Dallas. We run a lean specials board because we’d rather give homeowners a straight price the first time than play discount games with inflated numbers. What we do offer is grounded in how we actually work: free estimates, a written price before any work starts, and a 365-day guarantee on every repair. Wade Mercer and our Dallas techs stand behind these offers the same way we stand behind every job.
Current Offers
Free Service Call with Any Garage Door Repair
Book any repair and we’ll waive the service call fee. That covers the diagnostic visit to your Dallas home, so you’re not paying us to tell you what’s wrong. The repair quote you get is the written price you approve before we touch a single component, and it’s covered by the 365-Day Done Right Promise. Mention this offer when you call (254) 269-5837.
Valid through March 31, 2027. Mention this offer when you call (254) 269-5837.
Free Garage Door Safety Inspection with Any Opener Repair
When you book a garage door opener repair, we’ll include a full safety inspection of your door system at no charge. We check balance, cables, rollers, and the auto-reverse function that protects kids and pets. If we find something that needs attention, you get a written price for that work too, no pressure and no obligation. This inspection normally runs $89 on its own.
Valid through March 31, 2027. Mention this offer when you call (254) 269-5837.
$50 Off Garage Door Cable Repair
Most cable repairs in Dallas run $150 – $275 depending on cable type and drum condition. Take $50 off that when you book with Brock Garage Doors Dallas. Cables under tension are dangerous to work on yourself, so this is one repair you genuinely want a trained tech handling. We quote the price in writing before any work starts, and the repair is covered in writing for 365 days.
Valid through March 31, 2027. Mention this offer when you call (254) 269-5837.
Free Tune-Up with Any Spring or Opener Replacement
Replace a torsion spring, the thick coiled spring mounted above the door that bears most of the lifting load, or replace an opener and we’ll include a free tune-up at the same visit. That’s lubrication, hardware tightening, and balance adjustment on your new setup. It’s the kind of thing that keeps a new system running clean through Dallas summers when heat and humidity work metal hard.
Valid through March 31, 2027. Mention this offer when you call (254) 269-5837.
Senior & Military Courtesy Discount
We take 10% off labor for seniors 65 and older and for active or retired military personnel in Dallas. It’s a small way of saying thanks, and it stacks with our standing policies: free estimates and a written price before any work starts. Just mention it when you book. You’ll never have to negotiate for this one.

AfterWhy Our Offers Actually Hold Up
Garage door companies in Dallas sometimes run specials that disappear the moment the tech arrives. Ours don’t work that way. Every offer below is built on the same operating rules we follow on every job: a written price handed to you before work begins, background-checked uniformed technicians, and the 365-Day Done Right Promise. If a covered repair fails within a full year, we come back and correct it at no charge. That guarantee is in writing, not a verbal assurance that evaporates after the truck leaves.
We’re an independently owned and operated location within the Garrison Partners network. That means this is a local Dallas business run by Wade Mercer, but every job is held to The Garrison Standard: arrival windows, written pricing, a clean site, and the one-year guarantee. The Garrison Code governs how our techs run a call, from the moment they pull up to the moment they hand you the invoice. When you redeem an offer, you’re getting the same standard of work, just at a better price.
Our techs are trained on eight major brands: LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor. So whether your opener is a Genie from a decade ago or a newer Chamberlain with smart features, the fix we apply is specific to your system, not a generic workaround. That matters when you’re claiming a service call discount. You want the diagnosis to be correct the first time, because that’s where real savings come from.
Frequently Asked Questions About Our Dallas Garage Door Specials
Yes. A live person answers calls 24 hours a day, seven days a week, including holidays, and any current offer applies to emergency work the same as scheduled work. Tell the person who answers which offer you’re claiming when you call (254) 269-5837. The written price you approve will reflect the discount before work starts.
Call (254) 269-5837 and we’ll confirm your specific offer applies to the repair you need.
Generally, one offer per service visit keeps things simple and honest. The senior and military courtesy discount is the exception and stacks with any other current offer. When you call, we’ll tell you plainly which combination gives you the best price. No fine print games, just a straight answer.
No. The price we quote is the price you approve before any work starts. If we find additional problems during diagnosis, we’ll show you what we found, explain the options, and hand you a new written price for approval before proceeding. Nothing gets added to your invoice that you didn’t approve first. That policy applies whether you’re redeeming an offer or not.
Our trucks are stocked with common parts for LiftMaster, Chamberlain, Genie, Clopay, Amarr, Wayne Dalton, Craftsman, and Raynor systems. Cable repair parts, opener components, rollers, hinges, and many spring sizes are usually on the truck. For less common parts, we’ll order them and schedule the install.
Call (254) 269-5837 with your door’s brand and model if you want us to confirm parts availability before we come out.
