AfterWindows & Doors Services in Cotati, CA
If you live in Cotati, you’ve probably noticed it by now: the afternoon wind kicks up off the Pacific, funnels straight through the Petaluma Gap, and rattles the aluminum sliders that have been in your house since Lyndon Johnson was in office. We get calls every week from homeowners on Page Street and around La Plaza Park who are tired of hearing glass rattle in its tracks and feeling drafts move through the living room. TruePane Windows & Doors installs, replaces, and services windows and doors throughout Cotati, and a live person answers our phone at (888) 635-0804 any hour, any day. We measure every opening twice, we put our quotes on paper side by side, and we don’t leave the driveway until your manufacturer warranties are registered in writing.

Why Cotati Homeowners Choose TruePane Windows & Doors
We’re not the cheapest bid in Cotati, and we don’t try to be. What we are is the company homeowners call when they’ve been burned once and don’t intend to let it happen again. Dale Kessler started TruePane in 2008 after decades in the glazing trade, and the rule he keeps on the whiteboard hasn’t changed since day one: if the pane is not true, the job is not done. Every install in Cotati is covered by our Done Right Promise, which is plain language for: if something isn’t right, we fix it. No paperwork fights, no fine print that covers neither. Both manufacturer warranty layers get registered before our truck leaves your driveway, with durations stated in writing. We serve homeowners throughout 94931, from the post-war tracts near Cotati-Rohnert Park Unified schools up to the foothill edges off West Sierra Avenue, and our background-checked, uniformed technicians treat your home the way they’d work in their own mother’s.
Windows & Doors Services We Offer in Cotati
Window Installation
New window installation in Cotati means something specific here: setting glass to hold up against the Petaluma Gap. We install wood, vinyl, fiberglass, and aluminum lines, always shimmed level and flashed to shed the marine moisture that blows in off the Pacific. Learn more about our Window Installation in Cotati.
Door Installation
A door that binds in July and lets fog-damp air through in January is a door that wasn’t set right the first time. We install entry doors, French doors, and patio sliders that swing true on their hinges and seal tight against Cotati’s prevailing westerlies. Learn more about our Door Installation in Cotati.
Window Replacement
Most Cotati homes still carry their original single-pane aluminum sliders, which means most of our work here is replacement. We remove the old frame, inspect the rough opening, and set a dual-pane unit that meets California Title 24 energy code. Learn more about our Window Replacement in Cotati.
Impact Windows & Doors
Cotati isn’t a hurricane zone, but the Gap wind can throw branches and debris against west-facing glass with real force. Impact Windows & Doors in Cotati from PGT and CGI add a level of protection that standard glass doesn’t offer, plus they cut wind noise considerably.
Energy-Efficient Windows
Single-pane glass is the biggest energy leak in a Cotati tract house. Energy-Efficient Windows in Cotati with Low-E dual-pane glass and insulated frames stop the heat-loss cycle that runs your PG&E bill up all winter while the fog sits over the city.
Sliding & Patio Doors
West- and southwest-facing sliders in Cotati wear their tracks unevenly because of constant wind load on one side. We install Sliding & Patio Doors in Cotati with heavy-duty rollers and reinforced frames built for that exposure, not the generic hardware that comes in a box.
Glass Railing Systems
Decks and balconies in Cotati’s hillside pockets take the same wind and fog. We install Glass Railing Systems in Cotati-frameless and semi-frameless-with stainless hardware spec’d for marine exposure.
Custom Windows & Doors
Older Cotati homes sometimes have odd-sized openings that no stock unit will fit. We order custom sizes and shapes to match the original architecture, whether it’s a mid-century slider bank or a 1970s front entry.
Neighborhoods We Serve in Cotati
We work across all of 94931, and most jobs in Cotati get scheduled within a few days of your call. Here are the parts of town we see most often:
- Dove Creek / Falletti Ranch area - newer construction and higher-end window packages
- La Plaza Park / Downtown Cotati - mid-century homes and storefront-adjacent residential work
- Lilac Drive / Page Street corridor - classic post-1963 tract housing with original sliders
- West Sierra Avenue / Gravenstein Highway edge - wind-exposed lots where west-facing glass bears the brunt
- Myrtle Avenue foothill slopes - custom homes and deck railing work
Why Cotati’s Climate & Housing Affect Windows & Doors
Cotati sits squarely in the Petaluma Gap wind corridor, where strong, sustained marine westerlies funnel inland off the Pacific daily. That wind accelerates weatherstripping failure and seal degradation on every opening it touches. Most homes here were built between the mid-1960s and the 1980s with aluminum single-pane sliders that are now 40 to 60 years old and wholly mismatched to both these wind-driven conditions and California’s current Title 24 energy code. We routinely replace units that have fogged between the panes, frames that have racked out of square, and sliding door tracks that wear unevenly on the west side only. It’s a higher-frequency replacement cycle than you’d see in more sheltered inland Sonoma County towns, and it changes how we spec hardware for any job on this side of Highway 101.

FAQs About Windows & Doors in Cotati
Window replacement in Cotati typically runs $600 to $1,200 per opening for standard dual-pane units, with the final number depending on the material, the glass package, and whether the opening is on a wind-exposed west or southwest elevation. West-side openings sometimes carry a higher labor line item because the frames need extra shimming and heavier hardware. Call (888) 635-0804 and we’ll give you a written line-item quote for your actual windows, for free.
Yes. A live person answers our phone at (888) 635-0804 24 hours a day, 7 days a week. No voicemail tree, no callback form, no regional call center. When you call about windows and doors in Cotati, you talk to someone who can actually schedule your estimate.
No. We quote Cotati jobs on paper before any work begins, and the number on that paper is the number you pay. If we find hidden damage inside a wall or rough opening during the job, we stop and show you before doing anything that would add cost. No change orders, no arguing.
We handle all permitting required by the City of Cotati and Sonoma County for your project, and we don’t call the job done until the inspection passes. Replacement windows and doors in existing openings typically require less permitting than full-frame structural changes, and we’ll tell you exactly what your project needs before we start.
The Petaluma Gap pushes afternoon wind straight against west and southwest elevations in Cotati, and that constant pressure cycling racks frames out of square, cracks corner seals, and wears sliding door tracks unevenly on one side only. That’s why we spec heavier-duty hardware and extra shimming on those elevations as standard practice, not as an upsell. Call (888) 635-0804 and we’ll take a look at your windward openings for free.

What Cotati Customers Say
"Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S.
