Window Replacement Services in Cotati, Sonoma County

Deluxe Windows has been serving Cotati 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 Simonton, Milgard, and Anlin — we carry every material and style needed for Cotati's residential community. Cotati's unique circular street plan — the only such city grid in California — surrounds a charming central plaza, with housing ranging from 1940s–1970s bungalows to newer infill construction near Sonoma State University. Many of Cotati's older homes still have original single-pane aluminum sliders that contribute significantly to energy loss during Sonoma Valley's warm summers. Our certified installers handle all Cotati city permits and inspections so you don't have to.

Cotati's inland Sonoma microclimate delivers warm summers and mild winters, with temperatures noticeably warmer than coastal Petaluma. The city's housing stock is a compact mix of post-war bungalows, 1970s–1980s tract homes, and newer infill — most of which were built before modern energy codes required dual-pane windows. Simonton's Prism vinyl line offers an affordable, high-performing replacement option popular throughout Cotati's budget-conscious market. Our certified installers handle all permits and inspections. Most Cotati projects are completed in just 1–2 days.
