Mr-Glass Windows & Doors: The Dallas Owner’s Guide
If you have a Mr-Glass window or door with a failed part, we can source and install a compatible replacement in Dallas, with most jobs running $250 – $1,400 installed depending on the part and the work involved. We keep common Mr-Glass hardware on the truck, and for less common components we order direct and typically have it in hand within two or three business days. Most owners discover the problem the same way: a window that suddenly won’t stay open, a door that drags against the frame, or a lock that only catches if you lean your shoulder into it.
We’re an independent service provider, not a Mr-Glass dealer, which matters in one important way: we can match aftermarket equivalents or OEM parts without being tied to one source. That usually means a better price and a faster fix.
Which Mr-Glass Models This Applies To
Mr-Glass built windows and doors for a lot of Dallas homes in the 1990s and early 2000s, mostly aluminum-frame sliders, single-hung windows, and hinged patio doors. The parts that fail most often are the same across the model lines: roller assemblies on sliding windows and doors, spring balances on single-hung windows, and latch or deadbolt hardware on swinging doors.
Here’s the compatibility gotcha that trips up most owners: Mr-Glass used at least three different roller housing widths depending on the year and the series. A roller for a 2001 sliding door will not always fit a 1996 slider, even if both are labeled Mr-Glass. The only way to know for sure is to measure the housing, not just the wheel. Remove one roller assembly and measure the outer frame width in millimeters; Dallas homes built before about 2005 commonly use a 25mm housing, while later units often use 28mm. We carry both and confirm the measurement before we quote.
For spring balances, the Mr-Glass difference is the length and the stamp code on the side of the balance tube. The series code tells us the spring tension. Put the wrong tension in and the window won’t stay up, or it’ll slam shut when you let go. We match by the stamp, not by guessing. On OEM versus aftermarket: for rollers and balances, quality aftermarket parts from Caldwell or Prime-Line hold up every bit as well as OEM in Texas heat, and they cost less. For lock hardware that takes a specific key or matches the existing finish, we order OEM so it looks and keys the same.

Signs Your Mr-Glass Windows & Doors Is Failing
- The window drops shut when you let go. The spring balance inside the frame has lost tension or snapped. This is the single most common Mr-Glass failure we see in Dallas, especially on west-facing windows that sit in afternoon sun for years.
- The door or window grinds when you slide it. The roller wheels have flat-spotted or the bearings have seized. Aluminum tracks and constant heat make the rollers brittle. If you feel resistance and hear a gritty sound, the rollers are done.
- The sliding door is hard to lock, or the latch only catches halfway. Usually the door has sagged because the rollers wore down unevenly. The latch isn’t the real problem; the door dropped a few millimeters and the latch no longer lines up properly.
- Air leaks or visible daylight around the frame. The weatherstripping or the felt pile strips on a sliding unit have compressed with age. In a Dallas winter or July afternoon, you’ll feel it before you see it.
- The crank handle spins but the window doesn’t move. On casement-style Mr-Glass openings, the operator gear inside the crank mechanism has stripped. It’s a small part, but it means the window won’t open until it’s replaced.

AfterReplacement Cost & What’s Included
Here’s what we charge in Dallas for the Mr-Glass repairs we handle most often. These are installed prices, parts and labor together, and they’re the number on the invoice, not a range that changes after we start.
- Single-hung window spring balance replacement: $85 – $180 per window, including both balances.
- Sliding door roller replacement: $180 – $340 per door, including adjusting the door height after the swap.
- Sliding window roller replacement: $120 – $240 per window.
- Door latch or lock replacement: $90 – $220 depending on the hardware and whether we need to cut a new strike plate location.
- Casement operator replacement: $110 – $260 per operator.
What drives the spread is mainly part availability. Common parts we stock are at the lower end. OEM components we have to order add a day or two and a few dollars. Every price is written down before we pick up a tool, and the work is covered by our 365-Day Done Right Promise: if the part fails or the problem comes back within the year, we return and fix it at no charge.
DIY or Call Us?
Replacing a spring balance on a Mr-Glass single-hung window involves tensioned coils inside the frame. The balance tube is under load until the window is removed from the track, and if it lets go at the wrong angle, it can snap hard into your hand. We don’t think that’s a do-it-yourself job. The same goes for sliding door rollers: the door weighs 80 to 120 pounds and has to be lifted out of its track, which is a two-person job and a back injury waiting to happen with one.
What you can safely do is diagnose. If the window drops, if the door grinds, if the latch won’t line up, write down the symptoms and call us at (940) 204-5368. Trevor Nash grew up swinging a framing hammer and has rebuilt enough of these units to tell you honestly what it’ll cost before he ever sets foot in your door. We’ll come out, measure, and hand you a written number. If you’d rather try the fix yourself after we look, no charge for the visit. But most owners in Dallas find it’s cheaper than a trip to the ER and a door that still doesn’t slide.
FAQs
Most Mr-Glass components last 10 to 20 years, but Dallas heat shortens that on the low end. Spring balances on west-facing windows average about 12 years before they lose tension, and sliding door rollers in full sun often need replacing by year 10. If your home was built before 2005 and the parts are original, you’re likely near or past replacement age.
Generally no for rollers and balances. Roller wheels are sealed, and balance springs are riveted into the tube. Once either fails, the fix is a new part. Lock hardware is sometimes repairable if it’s just an alignment issue, but a stripped or broken latch is replaced. Call (940) 204-5368 and we’ll tell you which situation you have.
Most Mr-Glass part replacements take 30 to 90 minutes per window or door on site, assuming no frame damage. If we need to order a part, we schedule the install once it arrives, usually within three business days. You’ll know the timeline before we start.
We stock common Mr-Glass replacement parts including 25mm and 28mm rollers, common spring balance lengths and tension codes, and standard door latches. Uncommon OEM parts take a few days to bring in. We’ll tell you which applies to your window or door during the estimate, before anything is ordered.
