PGT Construction in Montclair, CA | Stallion Contractors
We provide independent PGT window and door service across Montclair, from WinGuard impact units to original aluminum sliders on 1950s and 60s tract homes. What makes our PGT work different here is that we plan every opening around Montclair’s shallow-slab, no-attic, narrow-lot rebuild reality, not just the window itself. That local planning is why homeowners call us when a PGT unit needs repair, replacement, or a proper tie-in to an addition. Reach us at (855) 600-3192 for a free estimate.
Why Montclair Residents Choose Us for PGT Service
PGT windows and doors are all over Montclair. Walk any street in the 91763 ZIP and you’ll spot WinGuard impact glazing on rebuilds next to original aluminum single-hungs on homes that haven’t moved in sixty years. We’ve spent years installing, repairing, and retrofitting both, and we work on PGT products every week across the Inland Valley. Ruben Montoya, our owner, grew up in Colton and learned construction at San Bernardino Valley College, where job-site work started before any business card existed. That hands-on background means our crew opens up a wall with the same care we’d give a house down the street, because around here, it usually is.
We use OEM PGT rollers, weatherstripping, glazing gaskets, and hardware whenever a unit is otherwise sound. We’re independent, not authorized by PGT, and that independence lets us recommend a re-glaze or roller swap on a Montclair tract home when a showroom would push a full replacement. One contractor. Every trade. From the roofline to the slab, your project managed start to finish.

Common PGT Construction Problems We Solve in Montclair
- Glazing seal and weatherstripping breakdown on aluminum frames. Intense Inland Valley sun bakes PGT aluminum frames year after year. The seals dry out, crack, and let water in at the sill. In Montclair, where summer temperatures run high and UV exposure is relentless, we see this on units that are only ten or fifteen years old. Replacing the glazing gaskets and weatherstripping with OEM PGT parts restores the seal before the stucco around the frame starts to rot.
- Sliding-glass-door roller and track wear on original PGT doors. Most original Montclair homes were built in the 1950s and 60s with PGT or similar aluminum sliders. Decades of grit and Santa Ana dust grind the rollers down until the door drags or binds. When the winds kick up, a worn track lets dust and air pour in around the panel. We replace the rollers, clean or replace the track, and adjust the panel so it closes tight.
- Frame-to-stucco interface cracking. Older stucco settles. It gets patched, re-patched, and sometimes knocked out for a remodel. Where a PGT frame meets that old stucco work, hairline cracks open up and let wind-driven rain past the flashing. In Montclair, where Santa Ana events push rain sideways, that interface is the first place we check.
- Corrosion and finish failure near slab-on-grade openings. Montclair’s tract homes sit on original slab foundations, and many have had grade or drainage changed over the years. When water pools near a door threshold, aluminum frames corrode and the finish fails from the bottom up. We re-detail the drainage at the opening and repair or replace the affected frame.
- Mismatched PGT units after partial swaps. Homeowners replace one or two windows here and there for budget reasons, then end up with a mix of original aluminum and newer vinyl in the same wall. We match what’s practical and tell you honestly when a full opening replacement makes more sense than another patch.
PGT Service in Montclair: What Local Conditions Mean for Your Equipment
Because most original Montclair homes sit on shallow slab foundations with no attic and narrow 50-foot lots, any addition or rebuild forces us to re-engineer the footing and roofline right where the new PGT windows and doors tie into the old stucco wall. On these lots, staging and access aren’t just logistics headaches. They become flashing and opening-layout problems. The crane or dumpster can’t sit where you’d like it to, the old stucco is original, and the new opening has to work with whatever footing is actually under it. We plan for that from the first measurement.
On a 1960s single-story stucco tract home near the Montclair core, our crew opened up a rear wall for an addition and found the original PGT aluminum slider had a failed sill flashing that had been letting wind-driven rain into the stucco since the last Santa Ana season. We re-detailed the flashing at the slab, replaced the worn rollers and weatherstripping with OEM PGT parts, and set the new impact-rated PGT units into the re-engineered opening before the stucco patch went back on. Good work doesn’t need a sales pitch, it needs the right materials and someone who knows what they’re doing.
PGT Models & Products We Service in Montclair
We service the PGT lines you actually find in Montclair. That includes PGT WinGuard Aluminum impact-rated windows and doors, PGT WinGuard Vinyl impact windows, PGT Premier Aluminum series, and the PGT Trademark aluminum single-hung and sliding-glass-door lines common on the original 1950s and 60s stucco tract homes. Our approach is repair-first when a unit is sound: OEM PGT parts for rollers, weatherstripping, gaskets, and hardware, with quality aftermarket glass or frames only where an OEM match isn’t practical. We stock the common PGT replacement parts locally so a Montclair repair doesn’t wait on a backorder. For deeper PGT expertise and full-service options, see our PGT sales & service page.

AfterPGT Service Pricing in Montclair
What you’ll pay depends on the condition of the existing opening, whether the stucco needs re-flashing, and whether the unit is being repaired or replaced. On a Montclair tract home with original framing, the opening work often drives more of the cost than the PGT unit itself, similar to what we see with PGT repair in La Verne.
| Service | Typical Cost in Montclair |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair | $400 – $1,800 |
| Home Addition | $45,000 – $130,000 |
Every estimate we write is a free, line-item quote. You’ll see the unit cost, the flashing and stucco work, and the labor split out plainly. Call (855) 600-3192 and we’ll walk the openings with you before quoting anything.

FAQs – PGT Construction in Montclair
Repair when the frame is straight, the glass is intact, and the only failures are worn rollers, track debris, and failed weatherstripping. That’s the most common case on Montclair’s original aluminum sliders, and an OEM PGT roller-and-seal job usually brings them back. Replace when the frame has corrosion at the threshold, the glazing seal has failed in multiple places, or the frame-to-stucco flashing is compromised beyond a simple re-detail. Call (855) 600-3192 for an exact assessment, estimates are free.
Yes. The new footing and roofline on a shallow-slab addition change the opening dimensions and the structural header above the window. We set the PGT units after the framing is re-engineered, not before, and we re-flash the old stucco interface so the new windows don’t inherit the old wall’s water problems. This is standard for us on Montclair additions and nearby PGT service in Upland.
Yes. PGT WinGuard impact-rated windows are built for coastal wind-borne debris zones, which means they handle Montclair’s Santa Ana gusts without flexing. The laminated glass also cuts UV transmission and wind-driven dust infiltration, which matters on a tract home where the original sliders leak at the track. For Montclair’s summers, the right Low-E coating makes a noticeable difference in heat gain.
Usually, yes. We match the frame profile and finish on the remaining original units or the newer vinyl units, whichever makes the wall look coherent. If an exact OEM match isn’t practical on a discontinued PGT line, we’ll tell you outright and give you the closest compatible option rather than selling you something that doesn’t line up.
Older stucco means the frame-to-stucco interface has to be cut carefully and re-flashed properly or you’ll get water where there wasn’t water before. Original wiring often runs through exterior walls near window and door openings, so we scope each opening before cutting. On slab homes, we check the grade at the threshold too, because drainage is half the battle with a PGT door. For a site-specific quote, call (855) 600-3192.
