PGT Construction in San Martin, CA | Toolbox Contractors
We install, repair, and replace PGT windows and sliding glass doors across San Martin’s ranch properties and custom homes, and the thing that sets our PGT services apart here is simple: we know how these units actually fail when they sit on a one-acre former-orchard parcel with triple-digit summer sun and county fire-hardening rules. We’re an independent contractor, not affiliated with or authorized by PGT, so our repair-or-replace call is based on the unit in front of us, not a brand program. If your PGT slider grinds, your west-facing glass is fogged, or you’re planning an addition that needs county plan check, call Norm Castellano’s crew at (855) 382-3257 for a straight answer.
Why San Martin Residents Choose Us for PGT Service
PGT windows and impact-rated sliders show up all over San Martin’s housing stock because they hold up to the heat and the fire concern that come with living on unincorporated county land. We’ve worked on PGT WinGuard aluminum and vinyl units on single-story ranch homes, older farmhouses, and the custom houses that replaced them. That means we know what to look for before a window that looks fine on the surface turns into a fogged IGU or a door that won’t budge.
Norm Castellano came up doing residential framing and full remodels across the Inland Empire before running Toolbox Contractors, and he’s the guy you call when a previous contractor left something that needs untangling before real work can start. Tell me what you’ve got and I’ll tell you what it actually needs. That’s the approach we bring to every PGT job in San Martin: we use OEM PGT rollers, glazing, and weatherstripping where the unit is still supported, and quality aftermarket hardware when OEM is discontinued or back-ordered. You get an honest assessment, not a sales pitch.
We also carry the full-scope capability that matters when PGT work intersects with something bigger. Need impact windows installed as part of a home addition? We handle it. Replacing a slider on an ADU that also needs a roof? One contract, one point of accountability. That matters on San Martin parcels where a window opening can trigger a whole cascade of county requirements.

Common PGT Construction Problems We Solve in San Martin
- Fogged or hazy glass on west- and south-facing units. San Martin summers push triple-digit heat onto windows that often have zero shade structure to break it. The IGU seal fails, moisture gets between the panes, and the glass clouds permanently. This shows up most on PGT WinGuard sliders and fixed panels on the afternoon side of ranch homes. We replace the sealed glass unit and re-glaze in place when the frame is still sound.
- PGT sliders that grind, stick, or won’t latch. A WinGuard slider serving as the main door from the house to the patio takes constant traffic, and San Martin’s dry, dusty air plus clay-heavy soil tracked in from outside packs the track with grit. Rollers wear out, the door drags, and the latch stops engaging. We replace rollers, clean and re-lube the track, and re-align the panel so it glides again.
- Frame and corner-weld separation on older PGT vinyl units. Years of thermal cycling, hot dry summers followed by wet winters, puts stress on vinyl corners. Older PGT vinyl windows on mid-century San Martin homes sometimes show stress cracks or separation at the welded corners, usually the first sign the frame is past its service life. We’ll tell you straight if repair makes sense or if replacement is the honest call.
- Weatherstripping and sill deterioration at exterior openings. When ember-resistant detailing and defensible-space maintenance get deferred, exterior PGT openings take more abuse than they should. Dried-out, cracked, or missing weatherstripping lets dust in during summer and moisture during winter rains, and sills on older farmhouses can rot where drainage was never properly flashed. We re-seal, re-flash, and replace sills before they compromise the opening.
- IGU failure across multiple panes on one elevation. When a whole west-facing wall has fogged glass, that’s not one bad unit, it’s a pattern. On San Martin parcels where reflectivity and afternoon heat stack up, we see three or four failed IGUs on the same elevation because they all aged under the same conditions. At that point we’ll price replacement versus piecemeal repair so you can make a real decision, not a patchwork one.
PGT Service in San Martin: What Local Conditions Mean for Your Equipment
San Martin is unincorporated, which means a PGT window or door package on any addition, ADU, or converted accessory structure gets permitted and inspected through Santa Clara County rather than a city building department. That’s not a small distinction. County plan check on wildland-urban interface parcels here routinely folds defensible-space and fire-hardening review into the same submittal as the fenestration, so your window and door package gets scrutinized against fire-resistant materials, glazing, and egress requirements at the same time the framing and foundation are. A contractor who mostly works in Morgan Hill or Gilroy submissions can get caught off guard by that. We plan for it from the first site visit, because it’s a given on nearly every San Martin parcel we touch.
Add the former-orchard reality on top of that. Much of San Martin sits on what used to be orchard land, and that means buried irrigation lines, old well casings, and clay-heavy soil that expands and contracts with winter rains. When we pull an old PGT door to re-flash the opening on a ranch home off Llagas Road, we’re just as likely to find a rusted irrigation riser behind the trim as we are a rotted sill. The soil moves, the openings shift, and that’s why a PGT slider that was installed square ten years ago might be racked now. It’s not the window’s fault. It’s the ground underneath it.
That combination, unincorporated county rules plus former orchard ground, is the exact reason PGT in Corralitos or other generic service pages don’t serve San Martin homeowners well. The window is only one part of what’s going on at the opening.
PGT Models & Products We Service in San Martin
We service the full spread of PGT product lines you’ll find on San Martin homes and additions. That includes PGT WinGuard Aluminum impact-resistant windows and sliding glass doors, the heavy-duty line that shows up on WUI parcels where fire-hardening review is part of plan check. We also work on PGT WinGuard Vinyl impact-rated single-hung and casement windows, the PGT Architectural Series vinyl windows and patio doors you see on remodels and custom builds, and PGT Aluminum Series sliding glass doors on older ranch homes and outbuildings.
On parts, here’s how we work: OEM PGT rollers, glazing, and weatherstripping when the unit is still supported and the parts are available. When OEM is discontinued or back-ordered for an older model, we match quality aftermarket hardware instead of leaving the door disabled while a part sits in backorder limbo. For fast San Martin turnaround, we keep common PGT roller assemblies, weatherstripping profiles, and glazing tape stocked so a slider repair doesn’t stall waiting on a shipment. If a frame or IGU is failing but the opening and anchoring are sound, we repair. If the unit is racked, sealed glass is gone across multiple panes, or it no longer meets current WUI or egress requirements, replacement is the honest call and we’ll say so.

AfterPGT Service Pricing in San Martin
Here’s what PGT-related construction work runs in this area, based on the scope of the job and the condition of the existing openings.
| Service | Price Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
| Home Addition | $45,000 – $130,000 |
What drives the cost on a San Martin job is the same thing that drives everything else here: the parcel. A simple replacement on a 1950s ranch with standard rough openings prices differently than impact windows on a WUI parcel where the county requires documented fire-hardening on the glazing package, or an addition that starts with trenching through former-orchard soil to set the foundation. Our free estimate walks the site, checks the existing openings, and gives you a written line-item quote so you know exactly what the number covers. Call (855) 382-3257 to schedule yours.

FAQs – PGT Construction in San Martin
Does PGT window or door work on my San Martin property need a county permit?
Yes, in most cases. Because San Martin is unincorporated, replacements and new window or door packages go through Santa Clara County rather than a city building department, and any change to an exterior opening that affects structure, egress, or fire-hardening typically requires a permit. Like-for-like replacement of a single window may slide through without one depending on scope, but additions, ADUs, and any work on WUI parcels almost always trigger county plan check. We pull the permits and handle the inspections so you don’t have to. Call (855) 382-3257 and we’ll tell you what your specific property needs.
Why are my PGT windows fogging on the west side of my ranch house?
That’s IGU seal failure, and it’s the most common PGT problem we see in San Martin. The afternoon sun on a west-facing wall with no shade structure pushes surface temperatures high enough that the seal between the glass panes eventually gives out, moisture creeps in, and the glass clouds permanently. It’s not a cleaning issue, and it won’t clear up. The sealed unit gets replaced, and if it’s happening on multiple windows on the same elevation, we’ll talk about whether piecemeal replacement or a full elevation package makes more sense. Call (855) 382-3257 for an honest read on your windows.
My PGT sliding door sticks and grinds – can it be repaired or does it need replacing?
Most of the time it can be repaired. The usual culprits are worn rollers and a track packed with grit from San Martin’s dusty summers and clay-heavy soil, and replacing the rollers and cleaning the track solves it. If the door is racked, the frame is separated at the corners, or the glass is fogged across multiple panes, repair stops making sense and we’ll tell you replacement is the honest call before we quote anything. Call (855) 382-3257 and we’ll assess it on site.
Do PGT impact windows meet the fire-hardening expectations for San Martin WUI parcels?
PGT WinGuard impact-resistant units are a common choice on WUI parcels because they add a layer of protection, but windows are one part of a fire-hardening package, not the whole thing. County plan check on San Martin properties in or near the wildland-urban interface typically reviews fenestration alongside defensible space, vent screening, and ember-resistant exterior details. We’ll make sure your window and door package fits what the county is asking for, and we’ll walk you through what else the property needs. Call (855) 382-3257 to talk through your parcel.
What surprises do you hit on former orchard parcels when installing windows or doors?
Buried irrigation lines, old well casings, and soil that moves. San Martin’s orchard history runs right under the topsoil, and when we open up an exterior wall to install or re-flash a PGT unit, it’s not unusual to find an abandoned irrigation riser or a root system right where the opening needs work. The clay-heavy soil also expands and contracts with winter rains, which is why an older door that was installed square can be racked now. It’s one more reason to work with a contractor who knows these parcels. Call (855) 382-3257 for a free estimate.
