PGT Construction in Gilroy, CA | Workshop Contractors
We provide independent PGT window and door installation, repair, and replacement across Gilroy and nearby communities like San Martin PGT service, from the older downtown core to the 1990s and 2000s tract neighborhoods on the east and south edges. The difference here is that our crews have worked on PGT units in walls that already moved during the 1989 Loma Prieta earthquake and the decades of hot, dry summers since. You get honest repair-versus-replace guidance from a general contractor who actually opens these walls, not a sales pitch from a manufacturer rep. Call (844) 384-3361 for a free estimate on any PGT work in Gilroy.
Why Gilroy Residents Choose Us for PGT Service
PGT builds impact windows and sliding doors that hold up better than most in seismic country and extreme heat, but no product ages gracefully when the rough opening behind it has shifted. That’s the job we take on. We’ve installed and serviced PGT WinGuard and Architectural Series units across Gilroy long enough to know where their vinyl frames, sashes, rollers, and seals actually fail after a decade of Santa Clara Valley sun and a few hard rainy seasons.
We’re general contractors first, which means when a PGT window leaks at the head because the flashing was never right, or a slider binds because the opening went out of square, we fix the whole assembly, not just the visible part. Noel Figueroa, our owner and lead contractor, learned framing and finish work on job sites across the Inland Empire before he ever picked up a PGT sash. He carries that same standard into every Gilroy project: square openings, straight lines, and flashing details that survive a second look and a wet winter.
We also keep OEM PGT sashes, rollers, locks, weatherstripping, and glazing moving through our supply chain so Gilroy jobs don’t stall waiting on parts from the Gulf Coast. For work on PGT products, visit our PGT sales & service page to see the full scope.

Common PGT Construction Problems We Solve in Gilroy
- Cracked vinyl sash and frame corners on WinGuard units. Gilroy’s summer days push 90-plus degrees and winter mornings drop near frost. PGT vinyl extrusions expand and contract through that cycle every year, and at the welded corners, the stress eventually shows as hairline cracks and separation. We assess whether the frame is still square enough for a sash swap or if the whole unit needs to come out.
- Sliding glass doors that grind, bind, and pool water in the track. The downtown and older Gilroy neighborhoods have wood-frame homes where foundation settlement and seismic movement pull the rough opening out of square. PGT sliders set into those openings lose their alignment, the rollers wear unevenly, and winter rain collects at the sill and tracks inside. We reframe and flash the opening, then install fresh OEM rollers and locks on a door that actually closes clean.
- Fogged insulated glass and failed perimeter sealant on south and west exposures. Units facing direct afternoon sun along the east and south Gilroy edges take years of UV and heat loading. The failure shows up as condensation between panes or peeling sealant at the frame-to-wall joint. We deglaze, replace the sealed unit, and reseal with a product rated for high-heat California exposure.
- Early-1900s to 1950s homes with PGT units in rough openings that were never square. Many downtown Gilroy homes went through retrofit work after Loma Prieta, but window openings were sometimes patched rather than reframed. The PGT unit sits in a parallelogram, so sashes scrape, weatherstripping gaps, and air leaks at the head and sill. We correct the opening before the window touches it.
- Head flashing leaks after a wet season. Gilroy’s winter rains come fast and expose every flashing shortcut. PGT windows with missing or backwards head flashing drip inside the wall cavity, and homeowners see water stains at the top of the frame. We replace the flashing, check the WRB tie-in, and seal the perimeter properly.
PGT Service in Gilroy: What Local Conditions Mean for Your Equipment
Gilroy splits cleanly around one event: Loma Prieta. The downtown core still carries unreinforced-masonry walls and chimney damage from 1989, and even wood-frame homes on those blocks have openings that shifted during the quake and were never fully squared. So when a PGT window or door goes into an older Gilroy wall, the job is never a simple drop-in swap. The rough opening has to be measured against the actual wall, not the original plan, then reframed, flashed, and sealed against a structure that has already moved. On the newer east and south tract edges, the walls are square, but the 1990s and 2000s production builds now need their second generation of windows, and those original PGT installs from twenty-plus years ago are hitting the end of their vinyl and seal life. That’s the local split we deal with every week: retrofit work downtown, replacement work on the edges. It’s why our Gilroy PGT quotes account for the condition of the opening, not just the price of the window. For a look at how we serve the broader area, see our Gilroy service area page.
PGT Models & Products We Service in Gilroy
We work on PGT WinGuard Aluminum impact windows and sliding glass doors, PGT WinGuard Vinyl impact windows and doors, PGT Architectural Series vinyl single-hung and casement windows, and PGT sliding and hinged patio doors. Our parts approach is straightforward: OEM PGT sashes, rollers, locks, weatherstripping, and glazing where the frame is sound and the manufacturer still supplies the part. Where OEM hardware is discontinued on older units, we specify quality aftermarket components that match the original fit and function. If the vinyl frame itself is cracked at the corners or the rough opening is failing, we’ll tell you straight that replacing the unit is the durable fix, and we’ll source the right PGT replacement for Gilroy’s seismic and climate exposure.

FAQs – PGT Construction in Gilroy
No, you don’t. We’re an independent construction contractor that installs, repairs, and replaces PGT products every week, and we are not authorized, sponsored, or endorsed by PGT. What matters for warranty coverage is whether the work is done to the manufacturer’s installation spec and the local building code, and that’s the standard we build to on every Gilroy job. Call (844) 384-3361 with your window’s model and age and we’ll tell you what your repair or replacement path looks like.
In Gilroy, that combination almost always means the rough opening has settled or shifted, usually from years of soil movement or seismic stress on an older wood-frame wall. The door frame gets pulled out of square, the rollers bind and wear, and the track loses its slope, so water pools at the sill and intrudes during storms. The fix is rarely just new rollers. We square and reframe the opening, reflash the sill, and then install fresh OEM rollers and a properly pitched track. Call (844) 384-3361 for an estimate on the full fix, not just the visible part.
Sometimes yes, sometimes no. It depends on what the rough opening looks like behind the trim. Many downtown Gilroy walls shifted during Loma Prieta and were patched rather than reframed, so the opening may be out of square or the surrounding framing may have hidden cracking. We measure the actual wall before quoting the job, and if the opening needs reframing, the quote includes that work. That’s the difference between a window that seals and one that leaks at the head every winter.
Yes, and we see it every year. Gilroy’s hot, dry summers push daytime temperatures past 90 degrees, and winter mornings regularly drop near or below freezing. That daily and seasonal expansion-contraction cycle stresses the welded corners of PGT vinyl extrusions, and after ten to fifteen years, hairline cracks and frame separation start to show. Units on south and west exposures fail fastest. We inspect corner welds and frame alignment on every PGT service call in Gilroy so you’re not surprised by a crack that’s been growing for three summers.
If the insulated glass unit is fogged, we can deglaze and replace the sealed unit while keeping the existing frame, which costs far less than full replacement. If the frame is cracked at the corners, the rough opening has shifted, or the flashing has failed so badly that water has been getting into the wall cavity, replacement is the honest answer. We’ll show you the condition of the frame and the opening during the free estimate, and we’ll quote the repair and the replacement side by side so you can decide without pressure. Call (844) 384-3361 to schedule one.
