Fast, Reliable Custom Windows & Doors Across Novato
Custom windows and doors in Novato carry a different set of calculations than most of Marin County. The 1960s and 1970s tract homes that dominate Ignacio and San Marin still hold original aluminum single-pane frames, while Bel Marin Keys canal-front homes face a salt-air corrosion rate that ages aluminum and steel hardware faster than anywhere else in the county. TruePane has worked both sides of that divide. We measure twice, quote side by side on paper, and register both manufacturer warranty layers before the truck leaves your driveway. Call (888) 635-0804 for a free estimate on any custom window or door job in Novato.
Why TruePane Windows & Doors Is Novato’s Preferred Custom Windows & Doors Company
Dale Kessler founded TruePane in 2008 on a rule that still governs every job: if the pane is not true, the job is not done. That standard travels with our crews into every Novato neighborhood, from the Hamilton historic district to the canalside lots of Bel Marin Keys. Our Custom Windows & Doors team has spent years learning what Novato’s specific housing stock throws at a replacement job, and we have the service record to prove it.
Novato homeowners call us because we answer the phone. A live person picks up 24 hours a day, seven days a week. Not a voicemail tree, not a callback form, not a regional call center. When you call about a fogged insulated glass unit on a Rancho Elementary-area ranch or a binding patio door near San Marin High School, you speak to someone who can schedule a background-checked, uniformed technician to show up when we say we will.
Every job carries the Done Right Promise. If something is not done right, we make it right. No paperwork fights, no fine print that covers neither party. We also register both manufacturer warranty layers in writing, with durations stated, before we leave the driveway. That is The Keystone Standard, and it applies to every window and door we install in Novato.
Our reputation in Novato is built on showing up, doing the work correctly, and standing behind it. We serve Custom Windows & Doors in Novato as a company that plans to be here in thirty years, not one chasing the next job.
Our Custom Windows & Doors Services in Novato
Custom Shape Windows
Novato’s ranch and split-level homes often feature arched, octagonal, or angled window openings that off-the-shelf replacement units cannot fill properly. We measure each opening twice and order custom shape windows to match the existing rough opening exactly. In Bel Marin Keys, where canal-facing elevations see driven salt air, we steer homeowners toward fiberglass or vinyl frames with composite hardware as the starting point, because aluminum will pit and oxidize within a decade.

Architectural Grilles & SDLs
Simulated divided lites and architectural grilles matter most in Novato’s Hamilton historic district, where converted 1930s and 1940s military buildings frequently require historically compatible window profiles before Marin County design review will sign off. We document the existing fenestration, source matching grille patterns, and install units that meet both the review board’s requirements and today’s energy code. Outside Hamilton, homeowners in the 1960s tracts often add SDLs to give tract house windows a more substantial look without sacrificing thermal performance.

Oversized Glass Panels
The hillside homes along Novato Boulevard and the larger custom builds in the western hills often call for oversized fixed glass panels that frame views toward Mount Burdell or the bay. Handling a 10-foot by 6-foot insulated glass unit takes a crew that knows how to set it without torqueing the frame or stressing the seal. We have the equipment and the hands for it. If a panel goes in out of true, the job is not done, and we redo it.

Commercial Storefront Glazing & Curtain Wall Systems
Novato’s commercial corridors along Grant Avenue and Redwood Boulevard include storefronts whose aluminum framing has taken decades of afternoon heat and marine wind. We replace storefront glazing and service curtain wall systems with materials rated for the specific exposure. For commercial jobs, we coordinate with the property owner on hours that minimize disruption to tenants. A leaking storefront sill is not something anyone should live with through the next winter storm.

Trusted Brands We Service in Novato
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. For Novato homeowners, that means we can quote side by side on paper so you see exactly what you are buying, and we stock common replacement parts locally to cut turnaround on repairs. In Bel Marin Keys, we routinely specify ES Windows and CGI products for their corrosion-resistant frame options and waterfront-rated hardware. We do not push one brand. We match the product to the exposure.
Common Custom Windows & Doors Problems We See in Novato Homes
- Corroded aluminum sashes in Bel Marin Keys. Salt air off San Pablo Bay pits aluminum frames and steel door hardware within 8 to 12 years. Homeowners see fogged glass, seized locks, and white oxidation powder on the sill. Fiberglass or vinyl frames with composite hardware are the starting point there, not an upsell.
- Original single-pane aluminum windows in Ignacio and San Marin tract homes. These 1960s and 1970s units have worn jamb hardware and failed weatherstripping. West-facing walls take wind-driven rain through the flange gaps in winter. We see the damp drywall and the swollen sills on nearly every replacement in these neighborhoods.
- Hidden framing and wiring problems in Hamilton conversions. The military buildings converted to housing in the 1940s often hide outdated wiring and undersized framing behind original window openings. When we open those walls, we find what the original builder left, and we document it before we touch it.
- Afternoon heat and seal failure citywide. Novato runs noticeably hotter on summer afternoons than coastal Marin cities like Mill Valley or Stinson Beach. That heat cycle accelerates thermal-seal failure in double-pane units installed in the 1990s retrofit wave. Fogged glass on a west-facing window that gets full afternoon sun is the most common service call we get outside Bel Marin Keys.
What Opening Up an Older Novato Home Actually Turns Up
Here is the reality of custom window and door replacement in Novato’s older housing stock: once the old frame comes out, you see what the original builder left behind. In 1960s ranches in Ignacio and San Marin, that is often undersized or damaged framing, failed waterproofing paper, and outdated wiring running along the rough opening. In Hamilton’s converted military buildings, it can be worse: original double-hung profiles that trigger Marin County design review before replacement can proceed, plus hidden code issues once the wall is open.
Novato’s permit process follows the California Building Code, and when a wall opens, the inspector sees what the inspector sees. Failed flashing tape, undersized headers, wiring that predates current electrical code: any of these can trigger a code upgrade as part of the permit. That is the single biggest reason a window replacement quote moves in Novato, and we handle it a specific way.
We inspect first. Before we write the contract, our technician opens the wall or probes the opening to see what the replacement will actually involve. Then we write allowances into the contract for known unknowns: flashing, framing correction, wiring upgrades, seismic strapping where required. If we find something after the wall is open that was not visible before, we stop work, price it in writing, and get your approval before we touch it. No surprise line items on the final bill. No change orders that you never saw coming. That is how we have done it in Novato for as long as TruePane has been on the job, and it is how Dale Kessler trained us to do it.
One recent job in the Hamilton historic district illustrates the process. A homeowner needed replacement windows on a converted 1940s military building. Our crew documented the existing double-hung profiles for Marin County design review, then sourced historically compatible wood sashes with low-E glass and argon fill. We coordinated the permit inspection after opening the walls, priced the discovered outdated wiring and failed flashing tape with written approval before touching it, and left the U-factor and SHGC within the county’s energy code for the original fenestration. The job took longer than a simple swap, but the owner never had to guess what the final bill would be.
Pricing for Custom Windows & Doors in Novato, CA
A standard custom-shaped window replacement in Novato typically runs $900 to $2,400 per opening, depending on the shape, frame material, and glass package. Architectural grilles and SDLs add $150 to $400 per window. Oversized glass panels start around $2,500 and can reach $7,000 or more for large fixed units with high-performance low-E glass. Full-frame replacements on 1960s tract homes, where we pull the old aluminum frame and reset the flashing, run $1,200 to $3,000 per opening. Jobs in Bel Marin Keys with corrosion-rated fiberglass or vinyl frames and composite hardware typically run 10 to 15 percent above the citywide average because the materials cost more and the exposure demands them.
What moves the price in Novato: the condition of the rough opening once the old frame is out, whether the job triggers Marin County design review, and whether the existing flashing and weather barrier need full replacement. We write allowances for those conditions into the contract up front. Call (888) 635-0804 for a free estimate with line-item pricing in writing.

FAQs - Custom Windows & Doors in Novato
Yes. Canal-facing homes in Bel Marin Keys sit on man-made waterways that drain to San Pablo Bay, and the salt air oxidizes aluminum window frames and steel door hardware within 8 to 12 years, faster than anywhere else in Marin County. We treat fiberglass or vinyl frames with composite hardware as the starting point there, because aluminum-clad products routinely fail their warranties under that exposure. The rest of Novato can use a broader range of materials, but the canalside lots need corrosion-rated products. Call (888) 635-0804 and we will walk you through what holds up on your elevation.
We stop, take photos, and price the correction in writing before we touch anything beyond the open wall. We write allowances into the contract for known unknowns like flashing replacement and framing correction, so the discovery is not a surprise. In Ignacio and San Marin ranches, we regularly find failed felt paper and undersized headers, and we fix them to current code before the new window goes in. You approve every line item before we proceed. Call (888) 635-0804 for an inspection-first estimate.
Yes. Converted 1930s and 1940s military buildings in Hamilton’s historic district often trigger Marin County design review for historically compatible window profiles before replacement can proceed. We document the existing fenestration, source matching profiles and grille patterns, and coordinate the permit inspection after opening the walls. The energy code applies too, so we install low-E glass with argon fill that meets county requirements for the original fenestration. Call (888) 635-0804 if you own a Hamilton property and need to know what the review process will require.
Fogged glass means the thermal seal between the panes has failed. In Novato, the afternoon heat in the interior valley accelerates these failures, especially on west-facing windows that take full sun from midday through evening. The insulated glass unit cannot be repaired; the glass package needs replacement. We replace the IGU and register the new manufacturer warranty in writing before we leave. Call (888) 635-0804 to schedule a measurement.
Yes. Novato sits in an interior Marin valley and runs noticeably hotter on summer afternoons than cities like Mill Valley or Stinson Beach. That means solar heat gain is a bigger factor, and we specify low-E coatings with lower solar heat gain coefficients for west- and south-facing openings in Novato than we would for a coastal home. The right glass package reduces both heat gain and cooling load. Call (888) 635-0804 for a glass comparison on paper.
