Mr-Glass Windows & Doors: The San Antonio Owner’s Guide
When a Mr-Glass window or door part fails, we typically install the correct replacement for $450 to $1,500 depending on the component, and most window part swaps are finished the same morning. Most owners discover a problem the moment a latch won’t catch, a sash drops, or a frame pulls away from the wall after a Texas storm. You’ll want the part matched to your exact Mr-Glass series, not a generic box-store substitute that almost fits but doesn’t seal.
We’re an independent San Antonio service provider, not affiliated with Mr-Glass. What we offer is parts matching, honest pricing, and a written quote before any work starts. Graham Stein spent decades framing and finishing homes before he started writing scopes of work down, line by line, so the price you sign is the price you pay. Write it down, price it once, do it right.
Which Mr-Glass Models This Applies To

Most Mr-Glass windows and doors in San Antonio fall into three categories: single-hung aluminum, double-hung vinyl, and sliding glass patio doors. Each uses different hardware. The easiest way to identify your window is the label etched into the corner of the glass or printed on the frame edge. Look for a small string of numbers and letters, usually two letters followed by four digits. That code tells us the series and the year it was made.
One compatibility gotcha we see often: Mr-Glass single-hung windows from the mid-2000s look identical to the later vinyl series, but the balance channels and pivots are sized differently by about a quarter inch. A homeowner who buys the earlier model’s part on a guess ends up with a sash that won’t stay up. That’s the difference between OEM Mr-Glass parts and a quality aftermarket equivalent. For balance hardware, tilt latches, and wheels, an OEM match is usually the safer call. For weatherstripping, sweeps, and exterior trim, a high-grade aftermarket part often performs as well and costs less. We stock both on our trucks, and we’ll tell you which one makes sense for your window rather than defaulting to whichever costs more.
Styles & brands we work with







Signs Your Mr-Glass Windows & Doors Is Failing
- The sash drops when you release it. The balance mechanisms inside the frame are worn or broken. On San Antonio summer days, heat softens old vinyl and speeds wear. A dropped sash that won’t hold is usually two worn balances.
- The latch will not catch or hits the keep misaligned. Repeated slamming pulls the meeting rail hardware out of square. If the handle is tight but won’t engage, the latch tongue is bent or the keep has shifted. Adjusting the pile may help, but most times this is a hardware replacement.
- You feel the breeze through a closed window. The weatherstripping has compressed or cracked, leaving a small channel for air. San Antonio’s dry heat bakes rubber and foam seals brittle within eight to ten years. New pile and top seals take care of it most of the time.
- The sliding door sounds like you are dragging furniture across gravel. The rollers have flat spots, or the track is packed with silt and pet hair. Once the roller bearings go flat, cleaning won’t fix it. We replace both wheels while the door is up.
- Water beads along the sill after rain. The frame has shifted or the sweep is gone. San Antonio’s quick downpours find every small gap. If the leak is at the corners, the corner seal within the frame has failed, and a sweep won’t be enough.
Replacement Cost & What’s Included

For most Mr-Glass window and door parts in San Antonio, installed prices run like this:
- Balance replacement (per window): $180 to $450, parts and labor included
- Latch / handle set: $120 to $260
- Weatherstripping and seals (per window): $140 to $320
- Sliding door roller set: $220 to $440
- Sliding door sweep and seal: $160 to $300
- Window sash replacement: $350 to $850 depending on glass package
The range comes from frame age, part availability, and whether the glass is part of the assembly. A 2005 single-hung with a simple latch is the low end. A newer triple-pane sash with argon fill sits higher. Every quote is a written price before the crew arrives. Included in the cost: the correct part matched to your Mr-Glass series, the swap itself, clean-up with a photo before the crew leaves, and our 365-Day Done Right Promise. If something we replace does not hold up, we come back and make it right.

Some things you can safely check: a sliding door track that needs cleaning, a visible gap where weatherstripping has pulled loose, or a handle screw that has backed out. Those are homeowner-level fixes. What we recommend leaving alone is anything under tension: window balances, sash springs, and sliding door roller cartridges. The springs that counterbalance a window can recoil fast enough to catch skin or break glass. If your Mr-Glass window won’t stay up, or the sliding door has come off its track, call us at (432) 233-0976. We’ll send a background-checked, uniformed technician with the parts on the truck, and you’ll have a written number before any work begins.
FAQs

Expect 8 to 15 years for weatherstripping, latches, and rollers in this climate. San Antonio’s heat and hard water shorten seal life compared with coastal Texas. Balanced parts typically need replacement between year 10 and 14, sooner if windows are opened daily. We can inspect and tell you what’s actually worn rather than selling a full rebuild. Call (432) 233-0976 for an exact quote on your windows.
Sometimes a latch can be bent and worked back into alignment, and a seal that has simply come unstuck can be re-seated. But window balances, failed rollers, and compressed weatherstripping almost always need replacement, not repair. We will show you the worn part before we quote the new one, so you see exactly what you’re paying for. Call (432) 233-0976 to schedule an inspection.
A single balance, latch, or seal swap runs 30 to 60 minutes. Two or three windows in the same visit usually take an hour and a half to two hours total. Sliding door rollers may take up to an hour because the door panel has to come out, get cleaned, and go back in. We’ll give you the time before we start, and we tell you also if we need to come back with a part not already on the truck.
We stock common balances, latches, rollers, sweeps, and weatherstripping for the most common San Antonio Mr-Glass series. Less common parts, like specialty glass assemblies or older hardware, take a few days to source. For the brands we stock parts for beyond Mr-Glass, our material partners include KraftMaid, Cambria, and Silestone. Call (432) 233-0976 with your window code and we can tell you before we come out whether it’s a same-visit fix.
