PGT Construction in Hillsborough, CA | San Mateo Construction
We provide independent PGT window and door service across Hillsborough, from full impact-rated window packages to surgical repair work on existing WinGuard units. For larger projects, many homeowners also rely on our General Contractor in Hillsborough to coordinate the full scope. The thing that makes our PGT work different here is simple: Hillsborough’s tree-preservation and slope-stability rules mean most PGT openings on hillside lots aren’t perfectly plumb, and we’ve spent years learning how to flash, shim, and seal these units so they shed winter rain instead of trapping it. San Mateo Construction isn’t authorized, sponsored, or warranted by PGT, and we’ll tell you plainly when a unit is worth repairing versus replacing. Call (855) 901-7266 for a free estimate.
Why Hillsborough Residents Choose Us for PGT Service
Noel Carrington has been working residential and light commercial jobs across San Mateo County for the better part of three decades, and PGT service in San Mateo is a core part of what we do, with PGT windows and doors showing up on a lot of those projects. Our crews have installed and serviced PGT units on Peninsula estates where freeze-thaw winters, hillside wind exposure, and defensible-detail requirements all land on the same wall. That’s not a hypothetical, it’s the typical Hillsborough job.
Tell me what you actually need, and we’ll figure out the right way to build it. When a Hillsborough homeowner calls about a sticking WinGuard slider or a hazy impact-laminate unit, we start by asking where the opening sits relative to the slope and the tree canopy. That usually tells us more than the model number does. We’re an independent outfit, which means we’re not obligated to push a new PGT package when a set of rollers and fresh weatherstrip will do. We carry genuine PGT replacement sashes, balances, rollers, and seals where the unit is current enough to support it, and quality aftermarket glazing when OEM is discontinued or priced past what the window is worth.

Common PGT Construction Problems We Solve in Hillsborough
- Vinyl WinGuard sashes that warp and stick after dry summers, then leak at the sill in winter. Hillsborough’s west-facing estate walls catch hours of afternoon sun through the dry season, and the vinyl on double-hung sashes expands and binds. When the first heavy winter rain arrives, the weatherstrip has compressed and failed. We replace sash balances and weatherstrip, and we’ll re-set the unit plumb if the opening shifted.
- Aluminum WinGuard slider tracks packed with oak and redwood debris. On tree-canopied lots, pollen, leaf litter, and bark drop into the track year-round. Rollers grind through it, panels drop out of plumb, and the slider eventually binds or won’t lock. We clear the track, replace the rollers, and adjust the panel so it glides without dragging.
- Hazy, clouded impact-laminate IGUs on full-sun elevations. Seal failure is common on Hillsborough units that face direct afternoon exposure. The glass fogs from the inside, and older laminated panes can delaminate at the edges. We’ll tell you if a sash replacement is enough or if the whole frame has to go.
- WinGuard French and entry door thresholds taking water from a hillside deck or landing. When a deck drains toward the opening, the sill pan rots and slab edges swell. We re-flash the rough opening, reset the threshold, and correct the drainage path so water moves away from the door instead of under it.
- Roof-to-wall flashing failures above PGT window banks. On steep Hillsborough lots, the roof above a window wall is often a little out of level or holding debris. We repair the roof and re-flash the head of the opening together, because water that gets past the roof flashing always ends up at the window. Our roof repair work runs $400 – $1,800 depending on the scope.
PGT Service in Hillsborough: What Local Conditions Mean for Your Equipment
Hillsborough is one of the few places on the Peninsula where a window or door package often gets locked in only after arborist and civil review settle the tree-preservation and slope-stability plan. The town requires design review and hillside standards on nearly every major remodel or addition, and that means we frequently have to set and flash a PGT opening to a building pad that shifted a foot or two from the original drawing. This is the part that’s genuinely unique to Hillsborough. On a steep, oak-shaded lot off a hillside street, we replaced the failed sashes and sticky rollers on a wall of PGT WinGuard Aluminum sliders where the original set had been installed before the final grading plan was approved. While we handle PGT repair in Highlands-Baywood Park too, this Hillsborough job was especially typical of the area. The openings were slightly out of plumb and the sills were draining toward the house. We re-flashed the openings, reset the frames plumb, and installed new OEM rollers and weatherstrip so the panels glide and the winter rain sheds away from the wall instead of into it.
What does this mean for a PGT owner in Hillsborough? If your house sits on a slope and your windows were installed by the original builder or a production crew, there’s a real chance the openings were never corrected after the final grade was approved. That’s not a knock on the window. It’s a knock on the sequencing. Our team checks plumb, sill slope, and drainage at every PGT service call, because on these lots, the wrapper matters more than the glass package.
PGT Models & Products We Service in Hillsborough
We service the full PGT line you’re most likely to find on a Hillsborough estate: WinGuard Aluminum impact-rated horizontal sliders and single-hungs, WinGuard Vinyl double-hungs and casements, Aluminum Series sliding glass doors, and WinGuard impact-rated French and entry doors. Our parts approach is straight: we source genuine PGT replacement sashes, balances, rollers, weatherstrip, and hardware where the unit is current enough to support it, and quality aftermarket glazing and seal kits when OEM is discontinued or priced past the value of the unit. We’re not going to tell you a $600 seal kit is a bargain when the frame is fifteen years old and the laminate is going. We repair sound PGT frames every time, and we recommend replacement when the frame, glazing, or weatherability is genuinely failing. See our PGT sales & service page for more on what we carry and how we work.

AfterPGT Service Pricing in Hillsborough
Here are the numbers Hillsborough homeowners ask about most, based on our San Mateo market pricing:
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair | $400 – $1,800 |
What drives the spread is the same thing that drives every Hillsborough project: slope. A window bank on a flat, accessible elevation with no tree conflicts costs a lot less to set and flash than one that requires scaffold work, arborist clearance, or re-flashing to a pad that shifted. A free estimate from us includes a look at the openings, the drainage path, and the surrounding roof and grade, because those are the things that determine whether your PGT repair lasts five years or twenty. Call (855) 901-7266 to talk it through.

FAQs – PGT Construction in Hillsborough
Yes, in most cases. We maintain sources for genuine PGT sashes, balances, rollers, weatherstrip, and hardware for WinGuard Aluminum and Vinyl lines that are still in production. For older or discontinued units, we use quality aftermarket glazing and seal kits. If we can’t get the right part, we’ll tell you that up front, and we’ll give you a replacement number tied to the actual condition of the frame. Call (855) 901-7266 and we’ll run the unit’s model and age against what’s available.
It’s almost always debris in the track combined with a frame that’s slightly out of plumb. Oak and redwood litter, pollen, and dust build up in the track all year, then winter rain turns it into grit that grinds the rollers. When the frame was set off-plumb, the panel drifts and the weatherstrip can’t seal evenly, so you get leaks at the same time the panel binds. We clean the track, replace the rollers, and re-set the frame if it’s off enough to matter.
Usually yes, if the grading plan moved the finished pad or changed the drainage path after the windows were installed. This is a Hillsborough-specific problem. When the pad shifts or the deck drains differently, the flashing designed for the original elevation no longer sheds water the way it should. We re-flash the rough opening, reset the frame plumb, and correct the sill slope. It’s the difference between a window that leaks every winter and one that doesn’t.
Probably a seal failure, but not always a full replacement. If the haze is between the panes, the IGU seal has failed and moist air got in. On a current WinGuard unit, we can usually replace the sash or the glazing pack without touching the frame. If the laminate is delaminating at the edge, the whole panel is done. We’ll show you the difference on site, and we won’t sell a new window when a sash replacement solves it.
Yes. We service WinGuard impact-rated French and entry doors, including threshold and sill pan repairs, slab resetting, and hardware replacement. Door failures on Hillsborough lots are most often drainage-driven: a hillside deck or landing routes water toward the opening, the sill pan rots, and the slab swells. We correct the drainage first, then repair or replace the door. Call (855) 901-7266 for an exact quote, estimates are free.
