Weather-Tight Windows & Doors for South San Francisco Homes

Built for Bayside Weather

South San Francisco's mix of older and mid-century homes wasn't built for today's wind-driven marine air, and drafty single-pane windows show it first. We replace them with full-frame or pocket units in vinyl, fiberglass, aluminum, or clad-wood, sealed for a weather-tight fit against the bay breeze. Energy-efficient, Title-24 and ENERGY STAR windows can trim heating and cooling costs by up to about 30%. We also install fiber-cement, engineered-wood, and vinyl siding, plus entry, patio, French, and sliding doors.

Why South San Francisco Chooses Golden State

We've installed windows, siding, and doors across the Bay Area since 1989, more than 30 years of hands-on work with a 4.8/5 rating across 393 Yelp reviews. Every window carries a full lifetime warranty, and our own licensed, bonded, and insured crews do the work, no subcontractors. We handle permits in-house, so your project stays on schedule. It all starts with a free, no-obligation in-home consultation.
