Professional window & door installation by Bay Area's most trusted team. Vinyl, fiberglass, wood & aluminum — every brand, every style, free estimate.
Deluxe Windows has been serving Gilroy homeowners with expert window and door replacement for over 30 years. From energy-efficient vinyl windows that meet California's Title 24 standards to durable systems from brands like Anlin, Milgard, and Simonton — we carry every material and style needed for Gilroy's growing residential market. Gilroy's South Valley neighborhoods — from the older Craftsman bungalows near Downtown Gilroy to the newer tract subdivisions east of Santa Teresa Boulevard — experience some of the most intense summer heat in Santa Clara County, regularly exceeding 100°F, making high-performance window replacement a priority for comfort and utility savings. Our certified installers handle all Gilroy permits and inspections so you don't have to.
Gilroy's inland Santa Clara County microclimate is defined by hot, dry summers and relatively cool winters — a combination where triple-pane or high-SHGC-rated windows make a measurable difference in comfort. Housing ranges from historic downtown Victorians and bungalows to large 2000s tract subdivisions in the Hecker Pass corridor. Anlin's Del Mar with dual-pane tempered glass is a go-to product in Gilroy for its exceptional heat rejection and lifetime warranty. Our certified installers handle all permits. Most Gilroy projects are completed in just 1–2 days.
