PGT Construction in Las Lomas, CA | San Mateo Construction
We provide independent PGT window and door installation, repair, and replacement across Las Lomas, CA. The one thing that makes our PGT work here different is knowing how Monterey County permitting and fog-belt moisture affect these units on older agricultural properties. We’re a licensed general contractor, not a manufacturer-authorized dealer, which means we spec parts and materials based on what actually performs in Las Lomas, not what a catalog says. Call (855) 901-7266 for a free estimate on any PGT project.
Why Las Lomas Residents Choose Us for PGT Service
Las Lomas doesn’t have a big-box service counter or a dedicated window shop. What it has is a lot of older farmworker housing, scattered ranch houses, and outbuildings that were fitted with PGT windows anywhere from five to thirty years ago. Those units don’t all fail the same way. Fogged glass, rotted sill framing, corroded aluminum tracks on barn sliders, UV-brittle vinyl on south-facing walls. We fix or replace them all.
Our crews have worked on PGT WinGuard, Aluminum Series, Hurricane Shield, and EnergyVista lines throughout the Pajaro Valley, and we also offer Pajaro PGT service for homes in that area. Noel Carrington, who runs San Mateo Construction, grew up around construction and has spent decades on residential work across the region. He’s the one who tells the crews to check the bottom plate before quoting a window swap on an old ranch house. Nine times out of ten, that’s where the real problem is hiding.
We’re local to the unincorporated parts of Monterey County. We know what the county reviewers ask for before they’ll sign off on a structural opening change. That matters when you live in Las Lomas and just want the window fixed without the permit desk becoming a second job.

Common PGT Construction Problems We Solve in Las Lomas
- Rotted bottom plates and sill pans behind PGT vinyl windows. On older farmworker housing in Las Lomas, the original flashing was often minimal or nonexistent. Coastal fog keeps the framing damp for weeks at a time, and water that wicks into the sill channel has nowhere to go. By the time the drywall shows staining, the wood is usually gone. We rebuild the rough opening, install a proper sill pan, and set the new PGT unit on stainless fasteners.
- Fogged insulated glass from failed factory seals. The Las Lomas microclimate pushes condensation into the window channel at night. When the glazing seal lets go, you get that permanent fog between the panes. We replace the glass unit rather than the whole frame when the vinyl and structure are still sound, which keeps the cost down.
- Warped or discolored vinyl frames on south- and west-facing walls. PGT WinGuard vinyl holds up well in most conditions, but after a decade of Pajaro Valley UV followed by soggy winters, the corners can move. A slightly warped sash means air leaks and a window that won’t close cleanly. We’ll tell you honestly whether it’s a sash replacement or a full window swap.
- Corroded rollers and tracks on PGT aluminum sliders in barns and outbuildings. Agricultural dust plus humidity grinds into the track and eats the roller bearings. These sliders often get ignored until the door won’t move at all. New rollers, cleaned and reset tracks, and the door works again. We service these on detached structures as well as main houses.
- Leaky flashing around PGT door openings on rural lots with sloped ground. Las Lomas sits on graded agricultural parcels, and because rain shed flows downhill, a door on the low side of the house catches more runoff than one on the high side. Failed flashing at the threshold rots the subfloor. We open it up, fix the framing, and rebuild the opening so water sheds away.
PGT Service in Las Lomas: What Local Conditions Mean for Your Equipment
Here’s something that catches people off guard. Las Lomas is unincorporated Monterey County. That means any PGT window or door change that alters the rough opening goes through Monterey County Building Services, not a city permit desk. And county reviewers here routinely require well and septic clearances to be on file before they’ll approve structural work. That’s a step you won’t run into if you drive five minutes into Watsonville for PGT repair in Watsonville, which has its own city building department. For a homeowner swapping a patio door or enlarging a window on an old ranch house, that clearance requirement can be the difference between a two-week permit and a two-month one. We handle the paperwork as part of the project and we know which drawings and details the county wants to see. It’s not glamorous, but it keeps the job moving.
PGT Models & Products We Service in Las Lomas
We install and service the full PGT lineup that’s common in the Pajaro Valley: WinGuard Vinyl, Aluminum Series, Hurricane Shield, and EnergyVista. For critical components like sash balances, weatherstripping, and locking hardware, we use PGT OEM parts to keep the original performance spec intact. When OEM glass or hardware is backordered or priced unreasonably, we’ll recommend high-quality aftermarket equivalents and tell you exactly what you’re giving up. We stock the common hardware and sealant profiles for PGT units locally, so most Las Lomas jobs don’t need a two-week parts hold. Learn more about our broader PGT sales & service capability.

A straight sash swap or glass replacement runs far less than a full rough-opening rebuild, and we’ll always quote the repair path first when the frame and sill are intact. The free estimate includes a look at the flashing, the bottom plate, and the surrounding trim, so the quote you get is the number we build against.

FAQs – PGT Construction in Las Lomas
Yes, if the replacement alters the rough opening. A like-for-like swap that doesn’t change the framing usually doesn’t trigger a permit, but any opening enlargement or structural change goes through Monterey County Building Services, and the county often requires well and septic clearances on file before signing off. We pull the permits and manage the paperwork as part of the job. Call (855) 901-7266 and we’ll tell you upfront whether your specific project needs county review.
The fog keeps exterior surfaces damp for weeks, and that moisture works into the sill channel, the joints, and the rough opening. Vinyl itself doesn’t rot, but the wood around it does when the flashing fails. We also see more seal failures here than in drier climates because condensation sits in the channel overnight. Regular inspection of the bottom corners and sill flashing catches most problems before the framing goes.
Usually, yes. Las Lomas farmworker houses tend to have smaller openings, simple trim profiles, and wood or stucco exteriors with minimal ornament. We match the new PGT units to the original sight lines and use trim details that fit the house rather than fighting it. When the original window was undersized for the room, we’ll show you options for a larger opening that still looks like it belongs on the house. Call (855) 901-7266 to talk through what your home needs.
A full window replacement typically runs from $4500 to $15000 depending on the unit size, the condition of the rough opening, and whether we’re doing one window or several. Impact-rated PGT units for a whole home start around $8000. A glass-only replacement on a fogged unit costs much less. Call (855) 901-7266 for a line-item quote after we look at the opening.
Yes. We replace rollers, tracks, and glass on aluminum PGT sliders in barns and equipment sheds. Those buildings face different conditions than a house, more dust, more humidity, and less regular maintenance, so we spec stainless fasteners and corrosion-resistant hardware that can handle it. For service on agricultural buildings, call (855) 901-7266 and let us know what you’re seeing.
