AfterWindow Company in Cotati, CA
Meridian Windows & Doors handles window replacement, window installation, and patio door installation for Cotati homeowners. Most Cotati jobs run $150 to $8,250 depending on the product and scope, and every quote is written down before work starts. If you’re dealing with fogged glass, a sticking slider, or original single-pane windows from the 1970s, call (817) 686-2228 and we’ll give you a straight answer on what it takes to fix it right.
Why Cotati Homes Are Different
Cotati’s housing stock runs older than most of Sonoma County’s newer developments. A large share of the homes here were built between the 1960s and early 1990s, which means single-pane aluminum windows, wood frames that have seen decades of morning fog, and patio doors that shake in the afternoon wind off the Petaluma Gap. The climate matters more than people expect: Cotati sits on a plain that funnels cool marine air inland, so west-facing windows take real sun load in summer while absorbing moisture through winter. That combination ages seals and warps sashes faster than the brochure numbers suggest.
Replacement specifications here lean toward low-E glass (a thin coating that reflects heat while letting light through) with higher wind-load ratings on patio doors, especially for homes near open pasture east of town or on lots along Old Redwood Highway. HOA requirements vary by subdivision, and Sonoma County’s energy-efficiency standards can affect which glass packages are allowed on a permitted replacement. We spec each Cotati job to the home, not to a stock list.
Our Main Cotati Services
The two things Cotati homeowners call us about most are full window replacements and patio door upgrades. Each service below has its own dedicated page with pricing tables, timelines, and warranty details.
Window Replacement in Cotati
Replacing windows in a Cotati home means accounting for original rough openings that have settled over 30 to 50 years, stucco or wood siding conditions that differ by neighborhood, and glass requirements driven by the Petaluma Gap’s wind patterns. We measure every opening individually before ordering, and the written quote you approve is the price you pay. Read the full breakdown at Window Replacement in Cotati.
Window Installation in Cotati
New construction and addition projects in Cotati call for window installation that meets current Sonoma County energy codes from day one. We coordinate with your general contractor or build team and order from manufacturer lines that keep lead times short for Cotati’s building season. Every install gets the same written price and 365-day guarantee as a replacement. Details are on the Window Installation in Cotati page.
Patio Door Installation in Cotati
Patio doors in Cotati take more weather than they should: afternoon sun, wind gusts off the gap, and winter rain that finds any gap in the threshold. We install sliding and hinged patio doors sized to your existing opening, with weatherstripping and thresholds spec’d for this climate. The full rundown on product options and pricing is on the Patio Door Installation in Cotati page.
