Most window and door calls we take in Larkspur come down to two things: fog between panes that won’t clear, or a wood sash swollen so tight you have to shoulder the door on a damp morning. Window replacement in Larkspur typically runs $850-$1,800 per opening depending on size, frame condition, and whether the opening needs custom sizing. We work throughout the 94939 zip code, from the flats along Magnolia Avenue up into Baltimore Canyon. If you need a straight answer on whether a window can be reglazed or has to come out, call (888) 635-0804 and a live person will pick up.

Why Larkspur Homeowners Choose TruePane Windows & Doors
Homeowners in this town tend to ask harder questions than most. Many have lived in their Larkspur house twenty or thirty years. They remember the contractor who caulked over rot instead of cutting it out. They notice when a frame is set a quarter-inch out of square because the door binds in August. That’s the customer we’d rather work for.
Dale Kessler founded TruePane in 2008 on a rule he still writes on the whiteboard: if the pane is not true, the job is not done. That rule governs how we work in Baltimore Canyon, where redwood shade keeps frames wet for days after a storm, and in the downtown flats near Twin Cities Church, where pre-war bungalows carry original trim nobody wants destroyed. Every technician is background-checked and uniformed. Every quote lists manufacturer lines side by side on paper. Both warranty layers get registered in writing before the truck leaves your driveway under The Keystone Standard, and the Done Right Promise means if something isn’t right, we come back and make it right without a paperwork fight.
Windows & Doors Services We Offer in Larkspur
Window Installation in Larkspur
New window installation in Larkspur often means working around non-standard rough openings in older homes, especially the Craftsman and Victorian stock along Magnolia Avenue. We measure every opening twice and set frames square before any glass goes in.
Learn more about our Window Installation in Larkspur.
Door Installation in Larkspur
Front doors and patio doors take a beating in Larkspur’s damp microclimates, swinging or binding as wood expands and contracts through fog cycles. We hang doors that clear their jambs year-round and seal tight against canyon moisture.

Window Replacement in Larkspur
Replacement work here frequently starts with more than glass. Rotted sashes in Baltimore Canyon often sit in rough openings where the king studs have gone punky too, and we address that before cutting the new unit in.

Impact Windows & Doors
Hillside neighborhoods above downtown Larkspur fall inside California’s Wildland-Urban Interface fire hazard designation, which means replacements there must meet fire-rated glazing and non-combustible frame requirements. We install impact-rated lines from PGT and CGI that satisfy WUI code without making the house look like a fortress.
Energy-Efficient Windows
Double-pane units with failed seals are common across Larkspur because repeated condensation cycles break down insulated glass over time. Upgrading to modern low-E units keeps canyon dampness on the outside and cuts the chill in north-facing rooms.
Sliding & Patio Doors
Sliding doors facing the Corte Madera Creek valley take constant fog and moisture, which compresses weatherstripping early and corrodes tracks. We replace worn rollers, rebuild jambs, and set new doors that glide without lifting.
Glass Railing Systems
For hillside decks overlooking the canyon, frameless glass railing keeps the view open while meeting Marin County structural and safety requirements. We fabricate and install railing that stands up to wet winters without fogging or delaminating.
Custom Windows & Doors
Larkspur’s older homes rarely take a stock-sized anything. When rough openings are out of square or a homeowner wants to match an original divided-light pattern, we order custom units built to the exact dimensions and trim profile.
Neighborhoods We Serve in Larkspur
We work across the whole 94939 zip code. Most Larkspur calls get a technician on site within a day or two, and we always confirm the arrival window by phone the evening before.

Why Larkspur’s Climate & Housing Affect Windows & Doors
Two forces work against every window and door in Larkspur. The first is Baltimore Canyon: a redwood-canyon enclave entirely within city limits, where old-growth canopy blocks direct sun so completely that exterior wood frames stay wet for days after any storm. That perpetual shade and humidity rots original wood-frame windows and doors faster than nearly anywhere else in Marin County. Contractors routinely pull a rotted sash expecting a simple swap, only to find the king studs and rough sill plate also soft and needing framing repair before any glass goes in.
The second is code. Hillside neighborhoods above downtown fall under the state’s Wildland-Urban Interface fire hazard designation. Window and door replacements in those zones must now meet fire-rated glazing and non-combustible frame requirements, a compliance layer most flatland cities don’t face. We quote those jobs knowing both what the county inspector will look for and what the canyon moisture will do to the frame ten years out.
Pricing for Windows & Doors in Larkspur
What you’ll pay depends on what’s behind the trim. A standard vinyl replacement window in Larkspur runs roughly $850-$1,400 per opening installed. Wood or fiberglass upgrades land closer to $1,200-$1,800. Custom sizing for non-standard openings on older homes, common along Magnolia Avenue and in the canyon, adds 15-30% over stock units. Entry door replacement typically runs $1,800-$4,500 depending on material and hardware. If rot has reached the framing, plan for additional carpentry before the unit goes in. We write fixed line-item quotes, no change orders, no surprise line items on the bill. Call (888) 635-0804 for an exact quote on your openings. Estimates are free.

FAQs About Windows & Doors in Larkspur
Expect $850-$1,800 per opening for most Larkspur homes, with custom sizing on older Craftsman and Victorian bungalows adding 15-30%. The variable is rot: canyon moisture frequently means framing repair behind the sash. Call (888) 635-0804 and we’ll walk your openings with you and write an exact price. Estimates are free.
Yes. Homes above downtown in the Wildland-Urban Interface zone must meet fire-rated glazing and non-combustible frame requirements under California code. We quote WUI-compliant lines like PGT and CGI so the install passes inspection the first time.
In most cases, yes. Many homes near Magnolia Avenue have original divided-light patterns and wide casing profiles that deserve to stay. We measure to the rough opening and order custom units that preserve the look while meeting current code.
A straightforward window swap takes half a day. Baltimore Canyon jobs with soft framing can run two to three days once the rot is cut out and the rough opening is rebuilt. We’ll tell you the honest timeline after the first look, before you sign anything.
No. We write fixed line-item quotes up front. If hidden rot requires additional framing repair, we document it, bring you to the opening, and get your sign-off before adding a dime. The Keystone Standard means everything is in writing, including both manufacturer warranty layers registered before we leave the driveway.

What Larkspur 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.
