ECO Window Systems Construction in Hillsborough, CA | Seaside Contractors
We provide independent ECO Window Systems service across Hillsborough, from ECO Window Systems sales & service to full replacements and re-flashing on estate properties. What makes our work here different is that Hillsborough runs its own design review plus geotechnical and drainage review, so we build glazing submittals into the schedule from day one. Call (833) 589-8103 for a free estimate.
Why Hillsborough Residents Choose Us for ECO Window Systems Service
We’ve installed and serviced ECO Window Systems glazing on estate remodels up and down the Peninsula for years, so we know how these units are built, sealed, and drained. And we’re an independent contractor, not affiliated with or authorized by ECO Window Systems. That independence means we’ll recommend the right fix for your windows and doors rather than whatever the manufacturer’s sales channel prefers. Glen Sorrento, our owner, grew up in Foster City and studied building construction technology at College of San Mateo before spending two-plus decades working through nearly every project type the Peninsula throws at a contractor, including ECO Window Systems repair in San Mateo and surrounding communities. He’s the guy clients call when they want a straight answer on an ECO aluminum slider and a GAF roof in the same afternoon. Let’s figure out what the job actually needs, then we’ll talk materials.

Common ECO Window Systems Construction Problems We Solve in Hillsborough
- Aluminum frame condensation and interior water staining. Hillsborough’s winter fog and rain combine with poorly flashed rough openings on sloped parcels, and we see water tracking down the inside face of ECO aluminum frames on street-facing elevations. The fix usually involves pulling the trim, re-flashing the rough opening, and resetting the unit with proper sill drainage.
- Failed or shrunken weatherstripping on ECO aluminum sliders. Wet-season storms push water across thresholds when the original weatherstripping has compressed or rotted. We source OEM weatherstripping where it’s still available and step to spec-matched aftermarket seals when it isn’t.
- Roller and track wear on heavy multi-slide doors. Estate homeowners open these doors daily to pools and terraces, and the rollers on a ten-panel multi-slide take serious abuse. We rebuild tracks and swap in new OEM rollers so the door moves like it should.
- Water intrusion at mullions and glazing seals on large picture units. Wind-driven rain on exposed ridge-top lots finds every weak seal. We strip and re-glaze the affected units and re-seal mullions with the right backer rod and sealant for coastal exposure.
- Threshold leaks on lift-slide patio doors. Hillsborough’s wet winters expose sill-pan failures fast. We pull the door, rebuild the rough opening with proper flashing and drainage, and reset the panel on new rollers and a fresh seal.
ECO Window Systems Service in Hillsborough: What Local Conditions Mean for Your Equipment
Hillsborough runs its own architectural design review plus separate geotechnical and drainage review, which means a window or door replacement on a street-facing elevation can require town design-review sign-off, not just a San Mateo County permit. If you’re swapping out an ECO picture unit or adding a multi-slide door on a home off Skyfarm Drive or a hillside parcel near Brewer Drive, the town wants to see glazing-unit submittals, framing details, and sometimes drainage calculations before the work starts. That’s a layer of scrutiny neighboring San Mateo or Burlingame projects don’t face. We build that review time into the schedule from day one, so the project doesn’t stall mid-install while you’re waiting on a design-review hearing. On a steep lot off Brewer Drive, a homeowner’s ECO Window Systems service in Highlands-Baywood Park and nearby areas addressed an ECO aluminum multi-slide door to the pool terrace that had been leaking at the threshold through two winters and the rollers were grinding. We pulled the door, found the sill pan was never flashed and the head was shimmed tight to a settling wall, then rebuilt the opening with proper flashing and drainage and reset the panel on new OEM rollers and a fresh seal. The terrace door now slides clean and the interior sill stayed dry through the next wet season.
ECO Window Systems Models & Products We Service in Hillsborough
We work on ECO Window Systems aluminum sliding glass doors, aluminum casement and awning windows, multi-slide and lift-slide patio doors, and fixed-picture and transom units. For parts, we source OEM rollers, weatherstripping, and hardware wherever they’re still available, and we step to spec-matched aftermarket extrusions and seals when OEM parts are discontinued. If frames are sound and glass is intact, re-sealing, re-flashing, and hardware replacement usually beats a full tear-out. We’ll tell you straight when it doesn’t.
