AfterFast, Reliable Window Replacement Across Cotati
Window replacement in Cotati usually falls into two camps: the wind-damaged west wall that can’t wait, and the homeowner who’s tired of condensation and drafts and wants the whole house done before the next fog season. Either way, you want a crew that knows what the Petaluma Gap does to a window frame. We’ve been replacing windows in Cotati for years, and we schedule work around the wind, not against it. Call (888) 635-0804 and we’ll walk through what you’re seeing, what it’ll cost, and when we can get to your house.
Why TruePane Windows & Doors Is Cotati’s Preferred Window Replacement Company
Cotati homeowners call us because the wind here doesn’t forgive a sloppy install. We’ve opened enough 1970s ranchers on the west side of town to know that a window that looks fine from the living room can have a failed seal, a rotted jamb, and a racked frame all at once. Our crews work on Cotati streets every week, so we don’t have to learn your house on the first visit. We already know how the afternoon westerlies hit your elevation, and we quote accordingly.
We’re led by Dale Kessler, a second-generation glazier who founded TruePane in 2008 on a rule he still keeps on the whiteboard: if the pane is not true, the job is not done. That rule governs how we measure, cut, flash, and seal every opening we touch. Cotati homeowners get the same Done Right Promise and The Keystone Standard every other TruePane customer gets: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves your driveway. Our techs are background-checked, uniformed, and they work in your home the way they’d work in their own mother’s.
Our Window Replacement Services in Cotati
We replace windows in Cotati homes built from the 1960s through the 1980s and everything newer. Most jobs are one of the four below, though plenty of Cotati houses need a combination.
Full Frame Replacement
When the rough opening is compromised, this is the only correct fix. In Cotati, west- and southwest-facing aluminum sliders rack from daily Petaluma Gap gusts, and the undersized framing behind them sags under that wind pressure cycling. Full-frame replacement lets us open the wall, repair or rebuild the rough opening, flash it properly, and set a new window that won’t repeat the old failure. We quote the framing repair as a visible line item on your written estimate so there’s no surprise when the wall is open. Most full-frame jobs in Cotati run $900-$1,900 per opening depending on size, exposure, and what the framing reveals.
Insert Window Replacement
If the original frame is sound and square, an insert window slips inside it and saves you the mess and cost of opening the wall. Cotati homes from the 1970s and 1980s often have frames that survived because they sit on the east or north side, away from the wind’s worst work. Inserts run $500-$1,050 per opening for a quality dual-pane vinyl or fiberglass unit with low-E glass. We measure twice, order tight tolerances, and seal the insert so Cotati’s evening fog doesn’t find a gap.
Storm Window Replacement
Some Cotati homeowners don’t want to replace the whole window, just the storm unit that’s gone cloudy or rattling in the Gap wind. We replace single storm windows and full sets, matching the original sightline where we can. Storm window replacement in Cotati typically runs $220-$480 per unit installed. It’s a smaller job, but the same rule applies: if the pane is not true, the job is not done.
Energy-Efficient Upgrade
Cotati’s marine fog and persistent westerlies make energy-efficient windows a practical upgrade, not a luxury. Original single-pane aluminum windows pull heat out of the house and draw condensation onto the glass every fog-bound night. We install dual-pane units with low-E coatings and argon fill, sized to California’s current Title 24 energy code, and we handle the paperwork for any rebate your manufacturer offers. Energy-efficient window upgrades in Cotati normally run $550-$1,200 per window, depending on size, glass package, and whether the frame needs full replacement or accepts an insert.

Common Window Replacement Problems We See in Cotati Homes
- Failed seals on west-facing sliders. Daily Petaluma Gap wind cycling racks aluminum frames until corner seals crack, the argon leaks out, and fog forms between the panes. We see this on nearly every original 1960s-1980s slider on the west or southwest side.
- Condensation and rotted wood jambs. Single-pane glass turns Cotati’s marine fog into condensation every night, and that moisture works into wood jambs and vinyl weatherstripping. By the time we open the wall, the jamb often needs rebuilding before the new window goes in.
- Track wear on sliding patio doors. The same westerly wind that racks window frames also presses against sliding glass doors, wearing tracks unevenly on the windward side. Doors bind in July because the wind has been working them all winter.
- Undersized or damaged rough openings. When we pull original aluminum sliders for full-frame replacement, we frequently find undersized rough framing that has sagged under years of wind pressure cycling. We repair or rebuild the opening before flashing tape goes down, which is why full-frame quotes from TruePane always include a framing allowance.
Pricing for Window Replacement in Cotati, CA
Cotati’s market is shaped by two facts: the housing stock is old enough that many jobs need full-frame work, and the wind adds labor on west-facing openings. Here are the ranges we quote for Cotati homes:
- Insert window replacement: $500-$1,050 per window
- Full-frame replacement: $900-$1,900 per opening
- Storm window replacement: $220-$480 per unit
- Energy-efficient upgrade (dual-pane, low-E, argon): $550-$1,200 per window
- West/southwest-facing full-frame with framing repair allowance: add $150-$400 per opening for the extra labor and hardware the wind side requires
We write fixed-price quotes, not estimates that drift. If your wall reveals framing damage we couldn’t see from outside, we stop, show you photos, and get written approval on the change before we touch another thing. Call (888) 635-0804 to schedule a free, no-obligation estimate in Cotati. We’ll inspect your openings, measure twice, and put the full quote on paper while we’re there.

FAQs - Window Replacement in Cotati
West-facing windows in Cotati fail faster because they take the full force of the Petaluma Gap wind corridor every afternoon. The sustained marine westerlies push against aluminum frames until corner seals crack and insulated glass units fog over, a failure we rarely see on east elevations of the same house. When you call for an estimate, expect us to quote west and southwest openings as a higher-labor line item with heavier-duty hardware specified. Call (888) 635-0804 and we’ll tell you what your elevation is up against.
If the frames are square and the rough openings are sound, inserts will do the job at a lower cost. But in Cotati’s 1960s-1980s tract stock, we often find the frames racked and the openings sagging on the windward side, which forces full-frame replacement. The only way to know is to open the wall or test the frame carefully. We’ll give you an honest read on the first visit and quote the option that actually fits your house. Call (888) 635-0804 to schedule that inspection.
When walls are opened for full-frame replacement, Cotati’s permitting process triggers a Title 24 energy compliance check, which means the new units must meet current efficiency standards for the climate zone, and any framing repair we uncover must be brought to code before the window is set. We pull permits, document what we find, and schedule inspections so the work passes the first time. You’ll see the permit line item on your written quote. Call (888) 635-0804 with your address and we’ll walk you through what your street typically requires.
Fog between the panes means the insulated glass unit’s seal has failed, and the answer depends on the frame. If the frame is still true and sound, we can replace the glass unit alone, which in Cotati typically runs $200-$400 per pane. If the frame has racked from wind cycling, the same seal failure will return, and replacing the whole unit through an insert or full-frame job is the only fix that holds. Call (888) 635-0804 and we’ll tell you which camp your windows are in.
Yes. For Cotati homes, our contracts include a wind-side framing allowance written as a visible line item, so you know before we open the wall what a racked rough opening will cost to repair, and we spec heavier-duty hardware on west and southwest elevations as a matter of practice. We quote manufacturer lines side by side on paper, register both warranty layers in writing, and back the workmanship with our Done Right Promise. No surprise line items, no arguing later. Call (888) 635-0804 for a free estimate and a contract that spells out exactly what the wind means for your windows.
