Custom Windows & Doors in Cotati - Free In-Home Measure, Written Price

Fast, Reliable Custom Windows & Doors Across Cotati

Cotati Door Installation and window work runs $450 to $4,800 per opening depending on size, glass package, and whether we’re doing a full-frame replacement or a retrofit insert. Most projects finish in one to three days once materials land. The real difference here isn’t schedule, it’s materials. Cotati sits in the Petaluma Gap wind corridor, and the shoddy aluminum sliders and hollow-core doors that came with your 1970s tract home were never built for what this valley throws at them. Our crews know every block from downtown Cotati to the Gravenstein Highway corridor. Call (888) 635-0804 and Dale Kessler, our founder, will make sure you get a straight answer before we ever send a truck.

Why TruePane Windows & Doors Is Cotati’s Preferred Custom Windows & Doors Company

We’re not the cheapest bid in Sonoma County, and we won’t pretend to be. What we are is the last call you’ll need to make on a window or door. TruePane Windows & Doors has been installing, replacing, and servicing windows and doors since 2008, and Dale Kessler started this company in 2008 with one rule written on the whiteboard: if the pane is not true, the job is not done. That rule still governs every measurement, every shim, every corner seal we touch in Cotati.

We answer the phone live, 24 hours a day, seven days a week. No voicemail tree, no callback form, no regional call center in another state. When a Cotati homeowner calls about a slider that won’t track or a picture window that fogged over, they talk to a person who knows what a Petaluma Gap westerly does to a west-facing frame. Our background-checked, uniformed technicians measure every opening twice and quote manufacturer lines side by side on paper, so you see exactly what you’re buying before you spend a dollar.

Every job carries the Done Right Promise and The Keystone Standard. Both manufacturer warranty layers are registered in writing, with durations stated, before the truck leaves your driveway. No paperwork fights. No arguing about what’s covered. We stand behind it.

Our Custom Windows & Doors Services in Cotati

Cotati’s housing stock is almost entirely post-1963 tract construction, and most of those windows have never been touched since the day they were nailed in. We handle the full range, but these four services come up most often in Cotati:

Oversized Glass Panels

Fixed picture windows and wide-view sliders are the defining feature of Cotati’s ranch and split-level homes. The original single-pane glass in those oversized openings flexes under the cyclic pressure of Gap westerlies, and when it flexes, the edge seal on the insulated unit fatigues. We install oversized panels with structural glazing and heavier-duty aluminum or vinyl framing rated for wind load. A typical oversized picture window replacement in Cotati runs $1,200 to $4,200, with low-E argon-filled glass adding $175 to $400 per unit.

Impact-Rated Glazing

Cotati isn’t a hurricane zone, but that doesn’t mean impact-rated glass is wasted money. The sustained marine westerlies that barrel through the Petaluma Gap carry debris, and west-facing windows eat the brunt of it. Impact-rated units with laminated interlayers also resist the pressure cycling that causes ordinary dual-pane seals to fail early. For west- and southwest-facing openings, we routinely spec Impact Windows & Doors in Cotati as standard on full-frame replacements. Expect to add $180 to $350 per window compared to standard dual-pane.

Custom Shape Windows

Octagons, half-rounds, eyebrows, gable-end triangles. Those shapes show up all over Cotati’s 1970s and 1980s tracts, and they’re the first windows to fail because the radiused corner seals crack under wind-driven pressure cycles. We template every custom shape on site, order from manufacturers like PGT and ES Windows who cut true radiuses, and set them with stainless flashing tape and proper sill pan drainage. Custom shape windows in Cotati typically run $700 to $3,500 per unit depending on dimensions and whether we’re doing a full-frame replacement or an insert.

Architectural Grilles & SDLs

Simulated divided lites preserve the look of a 1970s cottage without the maintenance of true muntins. We install SDL bars between glass from PGT and CGI, matched to your existing grille profiles. Cotati homeowners often ask for SDLs on street-facing windows to keep the neighborhood’s original character while upgrading to modern dual-pane glass. Grille and SDL additions run $40 to $120 per window depending on pattern complexity.

Trusted Brands We Service in Cotati

We’re an authorized installer for more than a dozen manufacturer lines including, PGT, CGI, and ES Windows. For Cotati’s wind-driven conditions, we lean on PGT for impact-rated glazing, ES Windows for oversized fixed panels, and CGI for custom shapes that need true radiuses cut to spec. We stock common weatherstripping, rollers, and replacement hardware locally, which means most repair parts for Cotati homes are on the truck or one day out, not three weeks from an out-of-state warehouse.

Common Custom Windows & Doors Problems We See in Cotati Homes

• West-facing aluminum sliders that rack under daily wind pressure. Cotati’s 1960s-1980s tract stock was built with aluminum single-pane sliders that were never designed for the Petaluma Gap. The frames rack, the corner seals crack, and marine fog condenses on the interior glass every morning. Full-frame replacement is the real fix, not another caulk job.
• Exterior doors that bind in July and leak in January. Original hollow-core steel-skin doors lose sealing integrity as wind-driven moisture infiltrates the jamb. The wood framing rots, the slab warps, and the door binds or hangs crooked. We replace the entire door unit with a properly weatherstripped, properly shimmed exterior door rated for this wind zone.
• Picture windows with failed seals on west and southwest elevations. The cyclic pressure swings from Gap westerlies fatigue the insulated glass unit’s edge seal. If you see fog between the panes that won’t wipe off, that’s a failed seal, not humidity in the house. Residential dual-pane replacement for a picture window in Cotati typically runs $450 to $1,200 depending on glass package and size.
• Sliding door tracks that wear unevenly. The wind loads rack the panel against the track, which wears the rollers on one side and produces that dragging, grinding feel. We install heavier-duty stainless roller assemblies and proper head jamb weatherstripping so the door glides and seals for another twenty years.
