PGT Construction in Highland, CA | Stallion Contractors
We’re an independent Highland contractor that installs and services PGT windows and doors every week, especially in the foothill-edge neighborhoods where county fire-hazard review changes how the job gets done. When a PGT unit fails here, it’s rarely just the window: it’s the flashing detail, the sill pan, or a stucco-to-frame transition that was never built for wind-driven rain off the slopes. We handle the whole opening, not just the sash. Call (855) 600-3192 for a free estimate on PGT work in Highland.

Why Highland Residents Choose Us for PGT Service
Ruben Montoya grew up in Colton, not far from Pepper Avenue, and he’s been on Inland Empire job sites long enough to know what the sun and the Santa Anas do to a window over ten or fifteen years. We’re not PGT-authorized and we hold no manufacturer partnership. What we have is field experience: the PGT sales & service work we do in Highland means we’ve opened up enough 1980s stucco walls to know which PGT assemblies actually clear San Bernardino County fire-hazard review and which ones get flagged at final. We use PGT OEM glass, gaskets, rollers, and hardware where the unit is still serviceable, and quality aftermarket seals and balances only when OEM parts are discontinued or back-ordered. For Highland homeowners, that means a straight answer about whether a window gets repaired or replaced, backed by someone who’s done both.

Common PGT Construction Problems We Solve in Highland
- Sun-baked seal and glazing gasket failure. South- and west-facing PGT units in Highland take years of intense inland UV and dry heat. The first sign is fogged insulated glass; the second is water staining at the sill. We pull the sash and replace the seal assembly before the frame rots.
- Wind-driven ember and rain intrusion at slider tracks. During Santa Ana events, rain gets pushed uphill into PGT slider tracks and weep holes. If the sill pan and flashing detail were never built for that exposure, water ends up inside the wall. We re-flash and re-drain the opening, then set the door properly.
- Impact-glazing laminate edge yellowing or delamination. Units that face the canyon wind corridors in Highland show edge yellowing on the laminate, plus hardware and roller fatigue from repeated gust loading. We replace the glass pack and rebuild the rolling hardware when the frame is still sound.
- Failed or skipped flashing at stucco-to-frame transitions. On 1970s – 90s tract walls in Highland, the original flashing was often improvised or missing. Hillside runoff during winter rain finds the rough opening. We rebuild the transition, re-flash, and set the unit to drain.
- Permit friction on unpermitted patio enclosures. Highland has a fair stock of older permitted-versus-unpermitted additions. When a PGT slider or window goes into a patio enclosure that was never recorded, the county’s fire-hazard review gets complicated. We sort out what needs to be documented before the window scope starts.
PGT Service in Highland: What Local Conditions Mean for Your Equipment
Highland sits where San Bernardino County fire-hazard review, wildland-urban-interface defensible-space rules, and hillside drainage all hit the same project. A PGT window or door scope on the slope side of 92346 usually needs fire-material documentation and a drainage plan alongside the county permit, not just a frame swap—something our General Contractor in Highland handles regularly. That’s not true in the flat of San Bernardino a few miles west. On a foothill-edge lot off the slope side of Highland, we opened up a 1980s stucco wall for a PGT WinGuard slider replacement and found the original flashing improvised and the sill pan letting winter runoff wick into the framing. We rebuilt the rough opening, re-flashed and drained the sill, and set the new impact-rated PGT unit with the glazing documentation the county wanted for the fire-hazard review. The homeowner got a door that no longer leaks in Santa Ana wind or winter rain, and it passed final without a setback. That is the difference between a contractor who knows Highland and one who just knows windows.
PGT Models & Products We Service in Highland
We install and service WinGuard Impact-Resistant vinyl windows and sliding glass doors, the PGT Aluminum Series (ALU) windows and doors for larger openings, PGT Vinyl Series double-hung and slider replacement units, and PGT impact-rated patio and multi-slide doors, including PGT in Redlands and surrounding areas. The OEM-vs-aftermarket call depends on the unit and the lead time: we keep common PGT rollers, balances, and gaskets on hand for fast turnaround in Highland, and order OEM glass packs when the laminated unit has to match the existing glazing schedule. For older PGT product families where parts are discontinued, we’ll tell you honestly whether to rebuild or replace.

FAQs – PGT Construction in Highland
Yes. Any window or door replacement on a Highland property in the wildland-urban interface overlay will likely trigger San Bernardino County fire-hazard review, and your PGT window’s glazing documentation has to be submitted with the permit package. We prepare that paperwork as part of the scope. Call (855) 600-3192 and we’ll check your parcel before you spend a dollar.
Fogged glass means the seal assembly has failed; leaking during Santa Ana wind means the sill pan or flashing detail is also gone. If the frame is still square and the rollers are sound, a glass-pack replacement plus a re-flash and sill rebuild runs toward the lower end of repair. If the frame has been wicking water for years, replacement is the more durable path. We’ll tell you which one your unit actually needs after we open it up. Call (855) 600-3192 for a straight answer.
Only if the flashing and sill pan are corrected at the same time. On sloped Highland lots, water gets funneled toward the rough opening, and a new PGT window set into the old flashing detail will still leak. We rebuild the transition, re-flash and drain the sill, then set the new unit. Call (855) 600-3192 and we’ll assess the opening before recommending a window.
Yes, for any window or door replacement that changes the rough opening or is located in the fire-hazard overlay. Same-size sash replacements in the flat parts of Highland sometimes slip through as over-the-counter work, but on the slope side the county wants the glazing documentation. We handle the permit as part of the job.
Yes, when it’s installed correctly. PGT’s impact-rated WinGuard line is built for wind-borne debris and pressure cycling, which is exactly what Highland foothill homes get during Santa Ana events. The weak point is almost never the glass; it’s the flashing and drainage detail around the frame. We install PGT units with that detail corrected from the start. Call (855) 600-3192 for a free estimate on where your openings actually stand.
