If your Mr-Glass impact garage door has a failed panel, broken spring assembly, or a track that’s pulling away from the jamb, we stock Mr-Glass-compatible parts and install them across Fort Worth, typically for $380 – $1,850 depending on what failed. Most single-part replacements (roller sets, cable assemblies, bottom seals) run $220 – $480 installed, while a full spring replacement or panel swap lands higher because of the tension work and hardware matching involved. Most Fort Worth homeowners discover the problem the hard way: a door that shudders halfway up, a cable that’s suddenly loose, or a grinding sound that gets worse every morning.
Mr-Glass builds impact-rated garage doors for the Texas wind and hail market, and the parts that fail first here are the ones that take the most cycle abuse: torsion springs, cables, and bottom weather seals. Fort Worth’s clay soil also does something people don’t expect. It shifts with our wet-dry seasons, which slowly torques the door frame until the track spacing drifts out of spec. That drift is what kills rollers and cables long before the door panel itself shows wear.
Which Mr-Glass Models This Applies To
Mr-Glass impact garage doors come in a few series lines depending on when the home was built and what wind-load rating the original permit required. The two we work with most in Fort Worth are the Mr-Glass 500 series (mid-range impact, common in neighborhoods built after 2006) and the Mr-Glass 700 series (heavier gauge, usually specified in Tarrant County areas with higher wind exposure). The model tag is on the inside face of the top door section, near the left roller bracket. It’ll show a series number, a dimension code (for example, 16×7 or 18×8), and sometimes the date code of manufacture.
Here’s the compatibility gotcha most hardware stores won’t tell you: Mr-Glass 500 and 700 series doors use different roller stem lengths. A roller for a 500 series will bolt into a 700 series bracket and look right, but it sits slightly shallow in the track, which accelerates track wear and eventually throws the door off balance. We stock OEM Mr-Glass parts where they’re still in production, and for discontinued hardware we use aftermarket equivalents machined to the same stem length, bearing diameter, and wind-load rating. On a Fort Worth home with a 700 series door, we will not substitute a lighter-grade roller to save money. It changes how the door handles a storm gust.

Signs Your Mr-Glass Impact Garage Doors Is Failing
- Door shudders or hesitates halfway up. This usually means one spring has lost tension or a cable drum is wearing unevenly. The door is fighting itself on the way up, and every cycle adds more wear to the rollers and hinges.
- Visible gap under one side when closed. Fort Worth slab movement shifts the door frame over time, so one side seats tighter than the other. That gap lets in dust, rain, and eventually rodents, and it means the track spacing is no longer square to the door.
- Grinding or squealing from the roller track. Rollers with worn bearings don’t roll, they scrape. On an impact-rated door, the roller is also part of the wind-load system, so a seized roller is doing structural work it was never meant to do.
- Loose or slack cable on one side. This is the one to stop using the door over. A slack cable means the spring system has failed or a drum has slipped, and the remaining spring is now holding the full weight of the door by itself.
- Door drifts down after opening, or won’t stay in place. That’s the spring losing its cycle rating. Mr-Glass springs are rated for a specific number of open-close cycles, and once they’re near that number, the door starts acting tired. Fort Worth heat shortens the cycle life of garage door springs slightly compared to coastal climates, so we see this in 8 to 10 years on doors that get used four cycles a day.

AfterReplacement Cost & What’s Included
In Fort Worth, here’s what we currently see on Mr-Glass impact doors:
- Roller set replacement (all four to six rollers): $180 – $340 installed
- Cable assembly (pair, includes drum inspection): $220 – $410 installed
- Bottom weather seal with aluminum retainer: $140 – $260 installed
- Torsion spring replacement (pair, matched to door weight): $380 – $720 installed
- Single impact panel replacement (500 or 700 series spec): $650 – $1,250 installed
- Track realignment and re-shim (slab shift correction): $240 – $480 installed
The range depends on the series, the door size, and whether the original hardware is intact or needs to be reworked. Every price includes the part, the labor, and a written line-item quote before we start. No change orders at the end. If the job needs a panel replacement, we match the impact rating to the existing door and confirm the wind-load spec against the original install, not just the visual profile of the panel. Our workmanship warranty on Mr-Glass door repairs covers the same 365-day Done Right Promise we put on every job in Fort Worth.
DIY or Call Us?
There are two parts of a Mr-Glass door an owner can safely check without tools: the bottom seal and the visible track bolts. If the rubber seal is cracked or pulling away from the retainer, that’s a straightforward swap. If you see a track bolt that’s visibly loose, you can note it and tell us about it on the phone. What you should not attempt yourself is anything involving the torsion spring, the cables, or the spring anchor brackets. Those are under enough tension to break bone or worse if they let go mid-repair. I’ve been in this trade long enough to treat every spring with full respect, and my crew never rushes that part of a job. Keith Yamada, who runs Lightwell Windows Fort Worth, learned that caution early at Los Angeles Trade-Technical College and it has stayed with him across every door he’s spec’d and installed in North Texas.
If you’re hearing noise or seeing slack cable, stop using the door and call us at (682) 900-6694. We’ll walk you through what you’re looking at, tell you whether it’s safe to operate, and give you a written price before we come out.
FAQs
In Fort Worth’s climate, a good pair of torsion springs on a Mr-Glass door lasts roughly 8 to 10 years with normal use, meaning four open-close cycles a day. If your door gets more cycles or faces a west-facing wall without shade, that number drops because heat accelerates the metal fatigue inside the spring coil. Call (682) 900-6694 and we can look at your model tag and give you a realistic lifespan for your specific door.
Some parts can be repaired: a bent track section can often be straightened, and a loose bracket can be re-shimmed. But torsion springs, cables, and impact panels are replacement items, not repair items, because once they’ve failed they can’t be returned to their original rating. We’ll always tell you which category your part falls into before we quote anything.
Most roller, cable, or seal replacements on a Mr-Glass door run 60 to 90 minutes from arrival to clean-up. A full torsion spring replacement runs about two hours because we match the spring to your door’s actual weight, not the original build spec, which can change if panels were ever replaced. Panel swaps run longer, usually a half day. Call (682) 900-6694 for an exact time estimate once we know your series and door size.
We keep the most common Mr-Glass 500 and 700 series rollers, cables, and seals on our Fort Worth service trucks. Springs are matched per door and we usually have the common sizes in stock at our local shop. If you have an older Mr-Glass model with discontinued hardware, we’ll order the correct aftermarket equivalent and give you the lead time before any deposit changes hands.
