PGT Construction in Ontario, CA | Workshop Contractors
We provide independent PGT window and door service across Ontario, from the older tract neighborhoods south of Holt Blvd to the newer planned communities on the north and east sides. The one thing that separates our PGT work here is this: we understand how Ontario’s expansive clay soils and Santa Ana wind loads interact with PGT frames, and we plan every installation around those two realities. If you’re dealing with sticking sashes, fogged glass, or drafty PGT units, call Noel Figueroa’s team at Workshop Contractors at (844) 384-3361 for a free estimate. We’re a full-service general contractor, not a manufacturer affiliate, and we’ve handled PGT sales & service across the Inland Empire for over a decade.
Why Ontario Residents Choose Us for PGT Service
Noel Figueroa grew up in the Vineyard neighborhood of Ontario, where the same generation of tradesmen who built those post-war tract homes eventually handed him his first framing hammer on an Ontario Home Remodeling job. That local history matters when we’re replacing PGT windows in a 1950s ranch on a slab that’s shifted half an inch over sixty years. We’re not reading a spec sheet and guessing. We’ve opened enough walls in this city to know what’s behind the stucco before we start. Our crews install and service PGT WinGuard Aluminum, WinGuard Vinyl, EnergyVue, and Commercial Series units on a regular basis, so we know which balance systems fail first, which weatherstripping wears out in Ontario’s heat, and when a repair is throwing good money after a frame that’s already warped. We source OEM PGT parts for critical components like balances and seals, and we’re honest when a full replacement is the smarter call. One contractor, every trade, from the roof down to the pavers.

Common PGT Construction Problems We Solve in Ontario
- Corner seal failure on original PGT aluminum windows in older tract homes. South Ontario’s post-war neighborhoods are full of mid-century homes still running original single-pane PGT aluminum units. Decades of thermal cycling, those 100°F summer days followed by cool desert nights, plus repeated Santa Ana wind loading, breaks down the corner seals. You get drafts, dust intrusion, and eventually water damage to the rough framing. We see it constantly in the blocks around downtown.
- Stucco cracking around PGT window openings. Ontario’s older stucco homes crack at the corners of window openings as the building settles and the Santa Anas flex the walls. Once that stucco cracks, the window’s weather seal is compromised, and moisture gets behind the flange. By the time a homeowner notices the draft, there’s often hidden rot in the rough framing. We reframe and reseal before installing the new PGT unit.
- Sash sag and failed weatherstripping on 1990s-2000s PGT vinyl windows. On the north and east side, those newer stucco homes with tile roofs are hitting twenty to thirty years old. PGT vinyl sashes, especially on west-facing elevations, absorb years of direct afternoon heat in Ontario. The vinyl softens slightly, the sash sags, and the weatherstripping compresses flat. That’s a repair we handle regularly with OEM weatherstripping and balance adjustments.
- Racked frames and glass stress cracks from slab movement. Downtown and south Ontario sit on expansive clay. When the slab shifts, window openings go out of square, and PGT frames get racked. The first sign is a window that’s suddenly hard to open or close. The second sign is a stress crack spreading from a corner of the glass. Ignoring it means the crack runs, and you’re replacing glass, not just adjusting the frame.
- Dust intrusion during Santa Ana events. Ontario’s fall winds push fine desert dust against every window and door on the property. If PGT weatherstripping is even slightly compressed, that dust finds its way in. Homeowners call us after the first big wind event of the season when their sills are covered in grit. We replace the weatherstripping, check the frame for square, and seal any gaps around the flange.
PGT Service in Ontario: What Local Conditions Mean for Your Equipment
Here’s the thing about Ontario that most window contractors in neighboring cities never deal with: the older residential core, especially south of Holt Blvd and near downtown, was built slab-on-grade with shallow footings over expansive clay. That clay swells when it’s wet and shrinks when it’s dry. Over fifty or sixty years, that cycle moves slabs enough to rack window and door openings out of square. When we replace PGT units in these neighborhoods, we routinely find ourselves stabilizing the opening before the new frame goes in, sometimes with pier-and-beam or post-tension solutions. That’s work you rarely see in Upland or Rancho Cucamonga, where the foothill soils drain differently. What it means for PGT owners is simple: a window that sticks or a patio door that drags might not be a broken part. It might be your slab telling you the opening has moved. If you’re seeing that, don’t just force the sash. Call us, and we’ll diagnose whether it’s the unit or the structure before recommending a fix.
PGT Models & Products We Service in Ontario
Our crews install, repair, and replace across the PGT product range. We work on WinGuard Aluminum, common on Ontario’s commercial and industrial buildings along the I-10 corridor and around Ontario International Airport. We handle WinGuard Vinyl, the most frequent residential replacement option in Ontario’s tract home neighborhoods. We service EnergyVue units, which Ontario homeowners often choose for west-facing elevations that get brutal afternoon sun. And we handle PGT Commercial Series for storefronts and tenant improvements. We source OEM PGT parts for critical components like balances, weatherstripping, and locking hardware to protect warranty coverage and maintain original performance. When OEM parts aren’t available for older discontinued units, or the cost doesn’t make sense on a twenty-five-year-old window, we’ll tell you straight and offer a quality aftermarket option. If the frame is warped or the glass seals are failing on multiple units, we’ll recommend full replacement instead of chasing repairs that won’t last. We install, we source, we stand behind it.

AfterPGT Service Pricing in Ontario
PGT service and installation costs in Ontario depend on whether you’re repairing an existing unit or replacing it entirely, the number of openings, and whether the installation requires structural work like reframing or slab stabilization. Here are the ranges we work within for the most common requests:
| Service | Typical Ontario Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
Window replacement typically includes removal of the old unit, inspection of the rough opening, any necessary reframing, installation of the new PGT window, insulation, and exterior sealing. Impact window installation costs are higher because the units themselves are heavier, the frames require stronger anchoring, and the installation often involves a full window and door system upgrade to meet code. A free estimate from us includes a site visit, measurements, a written line-item quote, and an honest assessment of whether repair or replacement makes more financial sense for your Ontario home. Call (844) 384-3361 to schedule yours.

FAQs – PGT Construction in Ontario
It depends on what’s causing the problem. Fogging means the glass seal has failed, and that’s a glass replacement at minimum. Sticking, on its own, might be a balance or a racked frame. But in a 1960s Ontario home, we often find that the opening has shifted from clay soil movement, and every repair we do compounds. If the frame is warped, the glass seals are failing on multiple units, or the opening needs structural work, full replacement with new PGT units is usually the smarter financial call. We’ll tell you which one applies after a site visit. Call (844) 384-3361 and we’ll assess your specific windows for free.
Yes, in most cases. Ontario requires building permits for window replacement, particularly when the opening size changes or structural work like reframing or header modification is involved. If the replacement is a like-for-like swap with no structural changes, some work may qualify for a simpler permit path. Ontario General Contractor Workshop Contractors handles the permit paperwork and coordinates inspections as part of the job, so you’re not navigating Ontario’s building department alone.
For most Ontario homes, we recommend PGT WinGuard Vinyl for residential replacement. It handles the thermal cycling of our hot summers well, it resists wind-driven dust, and it’s available in impact-rated configurations that give you better protection during Santa Ana events and improved energy performance. If you’re in an older home with a commercial storefront or larger openings, WinGuard Aluminum or Commercial Series may be more appropriate. The right answer depends on your home’s construction, elevation orientation, and existing framing.
Yes, in almost every case. PGT frames are available in a range of colors, finishes, and grid configurations. If the rest of your windows are intact and you only need two or three units replaced, we’ll match the frame color, glass tint, grid pattern, and profile as closely as the product line allows. For discontinued colors or styles, we’ll show you the closest current PGT option before we order anything. You’ll never get a surprise mismatch.
Expansive clay soil moves, and when it moves, so do the walls that hold your windows. In older Ontario neighborhoods, shallow footings mean that movement transfers into the rough openings of windows and doors more than it would in foothill cities. During installation, we check each opening for square before the new PGT unit goes in, and we address any racking or settling with structural solutions like pier-and-beam or post-tension stabilization, plus reinforced framing where needed. Skipping that step means a new window that sticks within a year. We don’t skip it. Call (844) 384-3361 to schedule a free estimate and we’ll tell you what your slab is doing.
