Mr-Glass Construction in Fontana, CA | San Mateo Construction
We’re an independent Fontana construction crew that installs and repairs Mr-Glass windows, sliding doors, and insulated glass units across the 92335, 92336, 92337, and 92331 ZIP codes. What makes our Mr-Glass work different here is the housing stock itself: much of Fontana’s 1950s – 1980s tract housing sits on shallow-footing slabs, which means window openings rack out of square and standard glass measurements often won’t hold up without field correction. Call (855) 901-7266 if you have a Mr-Glass unit that’s fogged, sticking, or leaking around the frame.
Why Fontana Residents Choose Us for Mr-Glass Service
We’ve pulled Mr-Glass vinyl sashes out of stucco ranch houses off Foothill Boulevard and reset them in newer subdivisions north of the 210. That matters because Mr-Glass windows behave differently in Fontana than they do on the coast: the Inland Empire sun bakes the vinyl, the Santa Ana winds drive grit into the weatherstripping, and the older slab foundations shift. We know what a fogged IGU on a 1960s home near the old Kaiser steel plant usually means, and we know when it’s worth resealing versus replacing. Noel Carrington, our owner, grew up helping his father pour concrete footings in San Mateo County, so slab movement and out-of-square openings aren’t an abstraction to us, they’re the reason we measure twice and order once.
We’re independent. We are not authorized, sponsored, or warrantied by Mr-Glass. We’re a local contractor who knows the brand from the field, not the factory. That independence means we tell you straight when a single fogged unit is worth fixing and when a whole wall of 1990s-era windows has reached the end of its service life. We work with OEM Mr-Glass replacement sashes, glass units, and hardware where they’re still available, and quality aftermarket IGUs and weatherstrip when the OEM parts are discontinued. For homeowners across Fontana who want one accountable team handling windows, exterior systems, and interior work under a single contract, we’re set up to do that.

Common Mr-Glass Construction Problems We Solve in Fontana
- Sun-warped vinyl frames and sashes. Fontana summers regularly top 100°F, and south- and west-facing elevations catch the worst of it. The vinyl on older Mr-Glass units can warp and bow, which breaks the seal and makes the sash drag or stick. We see this constantly on 1970s and 1980s tract homes where the original windows have been baking for forty years.
- Fogged and hazy insulated glass units (IGUs). Failed seals show up as fogging or a milky film between the panes. On the 1950s – 80s stucco homes around Fontana’s older neighborhoods, the original glazing has been cooking in dry heat for decades. We measure, order the right Mr-Glass or aftermarket IGU, and reset it with fresh sealant.
- Gasket and weatherstrip shrinkage. The Santa Ana wind corridor is dry and abrasive. Gaskets shrink, weatherstrip pulls away, and dust and grit get into the slider tracks. A patio door that once glided now grinds against sand. We replace the weatherstrip and recondition the track so the door actually closes against the wind.
- Racked window openings from slab settling. Fontana’s mid-century housing stock was built fast on shallow footings. When the slab settles, the rough opening twists out of square, and the glass cracks or the frame won’t seal. We check the opening with a square before ordering any Mr-Glass unit; no point putting a square window into a parallelogram.
- Leaking flashing and failed sealant around existing Mr-Glass units. Dry heat degrades exterior sealant faster here than in coastal climates. When sealant pulls back from the frame, water intrusion starts. We remove the old sealant, re-flash the opening, and reset the unit properly.
Mr-Glass Service in Fontana: What Local Conditions Mean for Your Equipment
Here’s something we tell Fontana homeowners that doesn’t apply the same way in Rancho Cucamonga or Rialto Mr-Glass service areas: much of the 92335 and 92336 housing stock sits on shallow-footing slabs poured during the steel-mill boom, and those slabs move. We’ve measured window openings in these homes that are out of square by a half-inch or more. A factory-standard Mr-Glass replacement unit won’t seat correctly in a racked opening. So before we order anything, we field-check the rough opening with a level and square, and if the framing has shifted, we re-square it or order a custom-cut unit to the actual dimensions. Skip that step and you get a new window that binds, leaks, and fails early. This is the difference between a contractor who has worked these specific Fontana neighborhoods and one who’s just installing glass to a spec sheet.
On a 1960s stucco ranch house off Foothill Boulevard in the 92335 ZIP, our crew found the original single-pane windows fogged and the frames racked out of square from slab movement. We re-squared the rough openings, ordered Mr-Glass replacement sashes and new IGUs, reset the units with fresh flashing, and resealed the sliders that were dragging on grit-filled tracks. The owner finally got windows that close in a Santa Ana wind. That’s the kind of job that defines our Fontana service area work.

No. San Mateo Construction is an independent general contractor. We are not authorized, sponsored, or warrantied by Mr-Glass. We repair and install their products because we see them regularly across Fontana and know how they behave in this climate. Independence means we recommend what’s actually right for the opening, not what a brand program tells us to sell.
Most single-unit repairs, like a fogged IGU swap or weatherstrip replacement, are done in one visit. Full window replacements on a typical Fontana tract home take one to three days depending on how many openings we’re resetting and whether the rough openings need re-squaring. We’ll give you a clear schedule before we start.
We service the Mr-Glass Vinyl Replacement Window series (single- and double-hung), Sliding Glass Door and patio door systems, Fixed and Awning units, and custom-cut IGUs for aluminum and wood frames. If you’ve got an older Mr-Glass product and aren’t sure of the model, we can usually identify it on site.
A single fogged IGU replacement typically runs a few hundred dollars, but if you’ve got multiple units failing or the frames are sun-warped, replacement may cost less over time than repeated patch repairs. Our window replacement work in Fontana ranges $4,500 to $15,000. Call (855) 901-7266 for a free measurement and exact quote.
