AfterWindows & Doors Services in Petaluma, CA
Petaluma sits in a wind corridor unlike most of the North Bay, and the windows and doors in the older homes here tell that story every summer afternoon when the fog rolls through. If you live in the Victorian and Edwardian blocks east of downtown or the 1960s tract homes on the west side, you’ve likely dealt with rattling sashes, fogged glass, or a front door that lets daylight in around the frame. We install, replace, and service windows and doors throughout the 94952 zip code, and a live person answers our phone day or night at (888) 635-0804. No voicemail tree, no callback form. Just someone who knows this town and knows what its houses need.

Why Petaluma Homeowners Choose TruePane Windows & Doors
We’re led by Dale Kessler, a second-generation glazier who started TruePane in 2008 because he was tired of seeing out-of-true installs and voided warranties treated as normal. Petaluma homeowners call us for the same reason they called their old hardware store before the chains moved in: they want someone who measures the opening twice, quotes manufacturer lines side by side on paper, and doesn’t walk away until the pane is true. That founding rule sits on the whiteboard in our shop: if the pane is not true, the job is not done. It governs every install we do from the Victorians near Walnut Park to the subdivisions west of Highway 101.
Residents in the Oakhill-Brewster district and the Cherry Valley area have told us they appreciate that our technicians arrive in uniform, background-checked, and prepared to work in their home the way they would work in their own mother’s. Every job carries a Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, with durations stated, before the truck leaves the driveway. That’s a square deal in a town that values one.
Windows & Doors Services We Offer in Petaluma
Window Installation
We install windows in Petaluma homes of every era, from clad-wood double-hungs that satisfy the design-review boards to modern fiberglass units built for wind loads. Every opening is measured twice, and every manufacturer warranty is registered in writing before we call the job done.
Learn more about our Window Installation in Petaluma.
Door Installation
A door that binds in July or lets fog-driven air through in August is a door that was never set right in the first place. We install entry doors, patio doors, and fully custom door systems in Petaluma, with weatherstripping that stands up to the Gap.
Learn more about our Door Installation in Petaluma.
Window Replacement
Replacing original rope-and-pulley sashes or failed aluminum sliders requires a different approach than new construction, and we’ve done both across Petaluma’s east and west sides. We remove the old, reset the opening, and install the replacement with a focus on sealing that holds against marine air.

Impact Windows & Doors
Impact Windows & Doors - Petaluma make sense for homeowners who want storm protection, sound reduction from Highway 101, or both. We’re an authorized installer for PGT and CGI, among other impact lines, and we quote them side by side on paper so you see exactly what you’re buying.

Energy-Efficient Windows
Single-glazed wood sashes from 1905 and aluminum sliders from 1972 both leak air, but they leak in different ways and need different fixes. We specify Energy-Efficient Windows - Petaluma glass packages based on actual conditions: afternoon wind, morning fog, and southern exposure off the west hills.
Learn more about our Energy-Efficient Windows in Petaluma.
Sliding & Patio Doors
A sliding door that grinds on its track or sticks when the humidity spikes is a door fighting its own frame. We service and replace Sliding & Patio Doors in Petaluma, paying particular attention to threshold sealing and roller alignment, which the Gap winds punish hardest.
Learn more about our Sliding & Patio Doors in Petaluma.
Glass Railing Systems
For decks and stair landings, Glass Railing Systems in Petaluma open sightlines without blocking the afternoon light when the fog burns off. We install code-compliant glass rail systems engineered for the openings they’re going into.

Custom Windows & Doors
When a stock size won’t work - and in a city with this many older houses, stock sizes often won’t - we order fully custom units built to the measured opening. Custom doesn’t mean slow, and it doesn’t mean vague pricing. It means the unit fits the house, not the other way around.

Why Petaluma’s Climate & Housing Affect Windows & Doors
Petaluma sits squarely in the Petaluma Gap, a documented break in the coastal mountains that funnels Pacific marine winds through the city at speeds and consistency that routinely exceed what Santa Rosa or Novato get. That sustained wind pressure, combined with the moisture-laden fog it carries, accelerates weatherstripping and door-sweep failure and drives rain into the original single-pane wood sash windows found across the city’s large Victorian-era east-side neighborhoods. We see it all the time: caulk that cracks in two years, exterior door seals that lose their compression, and wood sashes that swell and stick every summer when the fog lingers until noon.
The west side of Petaluma adds its own set of conditions. Those postwar and 1960s-70s tract homes with aged aluminum-frame sliding windows have lost their thermal breaks and seals, and the wind loading from the Gap finds every weak corner. In the locally designated and NRHP-listed historic districts, design-review guidelines require replacement windows to match original profiles and materials - vinyl double-hungs are routinely rejected, making clad-wood or true-divided-lite wood units the practical standard on those blocks. That code reality doesn’t apply a few miles away in unincorporated Sonoma County, but in Petaluma it’s the rule. We quote accordingly, and we know which manufacturers carry the lines that satisfy those review boards.

FAQs About Windows & Doors in Petaluma
Window replacement in Petaluma typically runs $700-$1,400 per opening for a standard retrofit double-hung, with clad-wood and true-divided-lite units in the historic districts running $1,200-$2,600 per opening. Your exact price depends on the window style, the existing frame condition, and whether design-review requirements apply. Call (888) 635-0804 for a written, line-item quote, no obligation.
If your home sits in a locally designated or NRHP-listed historic district in Petaluma, yes - design-review guidelines generally require replacement windows to match the original profiles and materials, and vinyl double-hungs are routinely rejected. We quote clad-wood and true-divided-lite units that satisfy those review boards, and we’ve worked with enough of them to know what gets approved. Call us and we’ll help you figure out whether your block falls under that review.
In many cases, yes - a failed insulating glass unit can be replaced without replacing the full window frame. Petaluma’s fog and condensation cycle causes seal failure more often than sunken glass, and we replace many IGUs in older sashes where the wood is still sound. We’ll tell you straight if the sash is too far gone and full replacement is the better spend. Estimates are free at (888) 635-0804.
Most window replacement jobs take one full day for a handful of openings, while a whole-house replacement across an older Petaluma home can run two to four days depending on the number of openings and the condition of the sills and trim. We complete most jobs in a single visit when the scope allows, and we don’t leave a second appointment hanging without a date. Call (888) 635-0804 for a timeline on your specific job.
Yes - when a permit is required for the scope of work, we pull it and the work gets inspected and signed off before we close out the job. That’s not the case on every simple like-for-like replacement, but when historic-district review or structural changes are involved, the permit is part of the deal. We’ll tell you up front whether your job needs one. Call (888) 635-0804 and we’ll walk you through it.
If your Petaluma windows or doors are fighting the fog, the wind, or just the last decade of deferred maintenance, give us a call. We’ll send a uniformed, background-checked technician to measure, quote manufacturer lines side by side on paper, and register both warranty layers before we leave the driveway. That’s how we’ve always done it, and that’s how we’ll do it on your house. Call (888) 635-0804 today to schedule your free estimate, or visit our home page to learn more about how we work.

What Petaluma Customers Say
"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."Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A.
