Windows & Doors Services in Novato, CA
There is a particular set of window and door problems that shows up again and again across Novato, and they trace back to how this city was built. Rows of 1960s and 1970s ranch homes went up fast, most with aluminum single-pane windows and hollow-core steel doors that have now been in place fifty or sixty years. The heat, the marine wind, and in Bel Marin Keys the salt air all compound the failure. If you’re in Novato and tired of fogged glass, sticking doors, or drafts you can feel from across the room, call TruePane Windows & Doors at (888) 635-0804. A live person answers, and we’ll give you a straight read on what needs replacing and what can be repaired.

Why Novato Homeowners Choose TruePane Windows & Doors
TruePane is led by second-generation glazier Dale Kessler, who founded the company on a rule that still gets written on the shop whiteboard: if the pane is not true, the job is not done. That standard travels to every job in Novato, from a single fogged sash in Ignacio to a full door replacement on a canal-facing home in Bel Marin Keys. Local homeowners keep our number because they know a background-checked, uniformed technician will measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before leaving the driveway. We carry a strong local reputation in Novato, with homeowners in San Marin and Hamilton repeatedly calling us back for second and third projects. The Keystone Standard means both manufacturer warranty layers are registered and their durations stated, and the Done Right Promise means if something is not right, we make it right without a paperwork argument.

We install new windows for homeowners who want a permanent fix, not a patch. Every opening gets measured twice and the rough opening is checked for square before the new unit is set.

Door Installation in Novato
A door that binds in July or lets daylight through the threshold is done. We install front entry doors, patio doors, and custom exterior doors with composite hardware where Novato’s marine air makes steel components oxidize fast.

Window Replacement in Novato
Most of the original aluminum windows in Novato’s 94945 tract homes are past saving, and replacement usually makes more sense than repair. We remove, dispose, and set the new unit so the flange seals against wind-driven rain on those west-facing elevations.

Impact Windows & Doors
Impact-rated glass is a practical choice for Novato homes near fire-prone open space or for anyone who wants better break-in resistance. Product lines include PGT and CGI, both of which we install as an authorized installer.
Learn more about our impact windows and doors in Novato by calling (888) 635-0804.

Energy-Efficient Windows
Novato runs noticeably hotter on summer afternoons than coastal Marin towns, and double-pane low-E units make a real difference in living-room comfort and utility bills. We quote specific glass packages so you can see the performance numbers on paper.

Glass Railing Systems
Glass railing systems suit the modern and mid-century homes across Novato, and we install frames and panels that are engineered for the wind loads this valley channels through the hills. The glass is specified to code and set with clean lines.
Learn more about our glass railing systems in Novato by calling (888) 635-0804.

Custom Windows & Doors
Hamilton’s converted military buildings sometimes require historically compatible window profiles under Marin County design review, and we handle custom sizing and profile matching. We do not shortcut the review process, and we do not install a generic product where a custom profile is required.

Why Novato’s Climate & Housing Affect Windows & Doors
Two things about Novato drive most of the window and door work we do here. First, the city’s 1960s and 1970s build-out left a huge inventory of original aluminum single-pane windows that are now corroding at the corners, losing their thermal seal, or simply worn out. Second, Bel Marin Keys introduces a factor no neighboring city has: a 1960s planned canal community whose homes sit on man-made waterways draining to San Pablo Bay. Salt air oxidizes aluminum frames and steel door hardware far faster there than anywhere else in Marin County. On canal-facing elevations, we routinely see aluminum window frames and door thresholds with heavy pitting within eight to twelve years. In that environment we treat fiberglass or vinyl frames with composite hardware as the starting point, not an upsell, and we warn buyers away from aluminum-clad products whose warranty will not survive the waterfront exposure. Add Novato’s interior-valley heat, which accelerates seal failure in 1990s-era double-pane units, and the strong afternoon marine winds that drive rain into worn door sills on west and northwest elevations, and you have a city where the right product spec matters more than the brand on the sticker.
Pricing for Windows & Doors in Novato
Honest pricing means you get a written, line-item quote before work begins, not after. As a general guide for the Novato market, a basic vinyl retrofit window replacement typically runs $700 to $1,400 per opening installed, depending on size and access. A mid-range fiberglass or premium vinyl window lands between $1,200 and $2,200 per opening. Entry door replacement in Novato generally runs $2,500 to $5,500 depending on door style, sidelights, and whether the rough opening needs repair. A sliding patio door replacement typically falls between $2,800 and $6,000. Impact-rated products cost more, and custom profiles in Hamilton’s historic district add engineering and review time. Seniors and veterans get a permanent 5% discount, and TruePane runs a $50-off any repair over $250 offer. An exact number comes from a free site visit; call (888) 635-0804 to schedule one.

FAQs About Windows & Doors in Novato
Window replacement in Novato typically runs $700 to $2,200 per opening installed, with vinyl on the lower end and premium fiberglass or custom profiles on the higher end. The exact number depends on window size, frame material, glass package, and how much rough-opening repair is needed. Call (888) 635-0804 for a free written estimate.
Bel Marin Keys homes sit on saltwater canals that drain to San Pablo Bay, and that salt air oxidizes aluminum frames and steel hardware years faster than in other Novato neighborhoods. We spec fiberglass or vinyl frames with composite hardware as the starting point on canal-facing elevations and steer clients away from aluminum-clad products whose warranties will not survive the exposure.
In Hamilton’s historic district, converted 1930s and 1940s military buildings often trigger Marin County design-review requirements for historically compatible window profiles. TruePane handles the custom sizing and profile matching, and we do not skip the review process. Call (888) 635-0804 and we will walk you through what your specific home requires.
No. TruePane quotes a fixed, line-item price before work begins, and the only time a number changes is if hidden damage requires additional scope that we document and approve with you first. You get a square deal on paper, not a surprise on the bill.
Most window installations and replacements of standard sizes are completed in a single visit. A full door replacement with rough-opening repair may take a day or a day and a half. We register both manufacturer warranty layers before the truck leaves your driveway, so the paperwork is done on the same visit. Call (888) 635-0804 to schedule a free estimate.

What Novato Customers Say
"Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T."Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L."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.
