AfterWindow Company in Larkspur, CA
Window work in Larkspur costs more than the Bay Area average because so much of the housing stock sits on steep, terraced lots with limited staging access, and many homes fall under strict hillside design review. You’ll typically spend $640 – $1,450 per window for full-frame replacement and $410 – $960 for a standard door swap, including labor. We’re Juniper Windows & Doors, and we give every Larkspur job a written price before any work starts. Call (682) 281-2168 if you’d like a number for your specific house.
Why Larkspur Homes Are Different
Larkspur sits at the base of Mount Tamalpais, which means two things for window and door work: marine fog that rolls through the flats, and abrupt elevation changes the moment you head uphill toward neighborhoods like Baltimore Park and the Madrone Canyon area. Most of the homes here were built between the 1940s and 1980s, so we’re often pulling out single-pane aluminum frames that have been fighting salt air and redwood duff for decades. The older casements and sliders in Larkspur frequently have rotted sills on the west-facing elevations where winter storms drive rain against the house.
Terrain shapes the job. A window replacement on a Magnolia Avenue bungalow with street-level access is straightforward. The same job on a hillside home off Madrone Avenue might require scaffolding, a lift, or carrying glass up a flight of stairs because there’s no room for a truck at the house. Those access costs are real and they’re why we walk every Larkspur job before we price it. Permitting is handled through the City of Larkspur’s building department, and if you’re in an HOA-managed pocket, the board usually wants to see product specs and finish colors before approval. We can walk you through that, and we quote the job in writing so there’s no surprise when the HOA asks for a change or the permit review takes an extra week.
Our Main Larkspur Services
These are the three jobs Larkspur homeowners call us about most often. Each one has its own page with pricing, timelines, and the local conditions that affect it.
Window Replacement in Larkspur
Replacing windows in Larkspur usually means pulling out failed aluminum or single-pane wood units and swapping in dual-pane glass that holds up to fog and coastal moisture. Hill towns like Larkspur have their own rhythm: older homes often have non-standard rough openings, so we measure every unit rather than assuming a stock size fits. Impact-rated glass is worth considering if you’re on a west-facing ridge where winter storms throw rain sideways. We cover all of it, quoted in writing before the work begins. Window Replacement in Larkspur has the full breakdown.
Window Installation in Larkspur
New window installation in Larkspur covers everything from a single-unit replacement to a full wall of glass added during a remodel. The tricky part here is working around redwood framing and older sheathing that predates modern building codes. We check the rough opening, the flashing, and the exterior trim before a unit goes in, because a window is only as good as the seal around it. And when the job is on a steep lot, we plan for how materials get up the hill. Window Installation in Larkspur explains what to expect.
Door Replacement in Larkspur
Front doors in Larkspur take a beating from winter storm fronts and afternoon sun on south-facing entries. A door replacement here often means replacing not just the slab but the frame, the threshold, and sometimes the sidelights if moisture has worked its way in over the years. We check the rough opening for rot, square up the framing, and install the new unit so it closes tight against winter wind. Door Replacement in Larkspur covers door types, local code, and pricing.

Pricing for Window Company in Larkspur, CA
| Service | Typical range in Larkspur |
|---|---|
| Full-frame window replacement (per window) | $640 – $1,450 |
| Insert window replacement (per window) | $410 – $960 |
| Standard door replacement (per door) | $410 – $960 |

Prices in Larkspur run toward the upper end of those ranges when the house sits on a slope with no direct truck access, because labor and material handling go up. Older homes with non-standard openings also cost more, since the framing and trim usually need rebuilding. Whatever the number is, you get it in writing before we start, and it doesn’t change unless you approve a change in writing first.
