PGT Construction in Hillsborough, CA | Daly City Construction
PGT window and door service in Hillsborough usually means one of three things: failed insulated glass on an older estate, a sliding door that binds after years of hillside movement, or new impact-rated units going into a design-review addition. We handle all three across Hillsborough’s 94010 ZIP, and we’re honest about the line between a repair that makes sense and a replacement that has to happen. We’re Daly City Construction, an independent contractor, not a PGT dealer or authorized service center. Call (866) 505-5254 when a PGT unit starts fogging, sticking, or leaking.

Why Hillsborough Residents Choose Us for PGT Service
We’ve spent years working with PGT aluminum and vinyl window and door systems on Peninsula hillside homes, so we know how these units behave in Hillsborough’s damp, wooded microclimate. That experience means we can tell an owner on the first visit whether a PGT frame is worth saving. Noel Cabrera, our owner, grew up in Daly City’s Westlake district watching postwar tract homes get re-framed and re-flashed, and he trained in construction technology at City College of San Francisco before years of hands-on residential work and PGT service in San Mateo. When we look at a PGT unit in Hillsborough, we’re looking at the frame, the glazing, the flashing, and the surrounding wall as one system, not as a parts list. Tell me what the house needs, not what you think it needs – then we’ll figure out the right fix.
We’re independent, which matters more than most homeowners realize. We’re not pushing a manufacturer’s line. If a PGT sash is sound, we repair it with OEM PGT glass, sash, and hardware where available. If OEM lead times or pricing are unreasonable, we use quality aftermarket glazing and weatherstripping, and we tell you which we’re using before any work starts. For Hillsborough owners, that straight answer is usually more valuable than a brand badge.

Common PGT Construction Problems We Solve in Hillsborough
- Fogged or failed insulated glass units. Seal failure between panes shows up most often on south- and west-facing PGT vinyl units here, where Hillsborough’s damp winters and summer fog cycles push moisture into the glazing cavity. The fix is a glass-unit replacement, not a whole new window, unless the sash itself is compromised.
- Water intrusion at sill pans and head flashings. On PGT windows set into stucco or wood-sided estates, the original flashing was often never upgraded for Hillsborough’s wooded, rain-heavy exposure. We see interior water stains that trace back to a head flashing that’s too shallow or a sill pan that drains into the wall instead of out of it.
- Corroded weatherstripping and rollers on PGT aluminum sliding doors. Shaded north elevations under heavy tree canopy here never fully dry out, so rollers pit and weatherstripping turns brittle years before a door should fail. We replace tracks, rollers, and gaskets, and adjust the panel alignment so the door actually slides.
- Out-of-square operation and binding sashes. Hillsborough homes sit on hillside foundations that move. An older PGT unit that once operated smoothly may now bind because the rough opening has shifted. Repairing the unit without addressing the framing around it only works if the movement has stabilized.
- Impact-rated upgrades for design-review additions. When a Hillsborough addition requires new PGT WinGuard or aluminum units, the openings often have to be re-framed for the heavier impact-rated system. We coordinate that work with the project’s structural scope so the new units sit square and drain correctly.
PGT Service in Hillsborough: What Local Conditions Mean for Your Equipment
Because Hillsborough has essentially no tract homes, nearly every parcel is a large-lot architect-designed estate subject to Planning Commission design review. That changes how PGT window and door work gets done here. On a Tudor or Mediterranean villa, a PGT window or door change on an addition often has to be specified in the design-review drawings and matched to the original facade before a single unit is ordered. In a neighboring city with standard subdivisions, you might swap a window in an afternoon, though our Millbrae PGT service handles similar cases. In Hillsborough, the same window is part of a reviewed architectural document. We’ve worked with owners and their architects on Crystal Springs Road, Chateau Drive, and other estate neighborhoods to get PGT units specified, approved, and installed without kicking the project back to the Planning Commission for a do-over. That sequence matters, because an owner who orders windows before design review approves them can end up with units they can’t legally install.
PGT Models & Products We Service in Hillsborough
We service the PGT Aluminum Series, including architectural and commercial-grade aluminum windows and sliding doors, the PGT WinGuard impact-resistant line, and the PGT Vinyl Series of double-hung and casement replacement windows.

AfterPGT Service Pricing in Hillsborough
What drives cost on PGT work in Hillsborough is the same thing that drives everything here: access, design review, and the condition of the surrounding structure. A simple glass-unit replacement on a ground-floor vinyl window runs differently than a full impact-rated window replacement on a second-story elevation with limited scaffold access. Here are the line items that typically apply:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition (including PGT openings) | $45,000 – $130,000 |
Every estimate is free and written line-item, so you can see exactly what’s allocated to glass, hardware, flashing, and labor. Call (866) 505-5254 to schedule a walkthrough on your Hillsborough property.

FAQs – PGT Construction in Hillsborough
In most cases, yes, if the windows are visible from the street or the work is part of an addition or remodel. Hillsborough’s design review process applies to nearly every exterior change on its large-lot estates, so we recommend checking with the Planning Department or your architect before ordering units. We’ve coordinated PGT specifications through that review on multiple Hillsborough projects and can work directly with your design team. Call (866) 505-5254 and we’ll help you map out the sequence.
If the frame is sound and the rough opening is stable, we repair: replace the failed insulated glass unit, new rollers, new weatherstripping, and realign the panels. If the frame has corroded through, the sill pan has rotted, or the opening has shifted out of square beyond adjustment, replacement is the honest call. We’ll show you the evidence either way.
Yes, when they’re flashed and sealed correctly for this specific climate. PGT’s aluminum and vinyl lines are built for coastal exposure, but Hillsborough’s tree canopy and winter rain mean sill pans, head flashings, and drainage paths have to be detailed properly at installation. Units that were installed years ago with builder-grade flashing will leak regardless of how good the window itself is. Call (866) 505-5254 if you’re seeing water stains or condensation between panes.
Usually yes, but the rough openings have to be re-framed or shimmed square before the new PGT units go in. On hillside homes where foundation movement has shifted the framing, installing a new window or door into an out-of-square opening guarantees binding sashes and short seal life. We address the opening first, then set the unit. For larger additions that include PGT openings, see our work across the Hillsborough service area.
We do this on nearly every Hillsborough project. The town’s strict design-review process and large-lot setbacks mean arborist reports and geotechnical input are routine before we break ground, especially on sloped parcels where retaining walls and drainage are scrutinized. We coordinate with those professionals as part of our general contracting scope. For PGT-specific work in Marin County, see our PGT service in Sausalito page or our PGT service in Belvedere coverage.
