If a window is failing in Larkspur, call (817) 686-2228 for a free estimate and a straight answer on what it will cost.
Why Larkspur Homes Are Different
Larkspur sits at the base of Mount Tamalpais, and that geography shapes the work. Many homes climb uphill from Magnolia Avenue, which means crews are often working on slopes, carrying units up stairs, and setting ladders on ground that isn’t level. That’s routine for an experienced window crew, but it changes how the job is bid and how long it takes.
The housing stock spans a wide range, from 1920s-era cottages near downtown to mid-century ranchers in the flats and newer hillside builds with broad glass facing the bay. Older frames in Larkspur are rarely square and rarely standard sizes, so replacement units are often custom-ordered rather than pulled off a shelf. Marine fog is a constant. Wood sashes swell and stick; aluminum frames pit; caulk and seals break down faster than they do inland. We spec glass and frame materials for that exposure, including low-E coatings that reflect heat while letting light through.
Permitting is another Larkspur-specific item. Many homes fall under the city’s design review process, particularly for visible elevations and any change to a door footprint. We pull permits when the job requires them, and we make sure the paperwork is right before the first cut. Homeowners in areas like Madrone Canyon and Palm Hill often ask about this first.
Our Main Larkspur Services
Most Larkspur homeowners call us for one of two things: replacing windows that have failed, or putting new windows and doors into a remodel or addition. Each service has its own Larkspur page with pricing, timeline, and what to expect.
Window Replacement in Larkspur
Replacement means pulling the old sash and frame components and setting a new unit into the existing rough opening. In Larkspur, where homes range from 1920s cottages with non-standard openings to 1980s builds with failing seals, most work is measured, ordered, and custom-fit. Fogged double panes, rotted wood sills, and crank-out casements that no longer seal are the most common calls we field here. We walk the house, measure every opening, and write the price down before ordering anything. Window Replacement in Larkspur covers the full process, including how we handle old frames and what a typical job costs.
Window Installation in Larkspur
Installation is for new construction, additions, and remodels where the rough opening is being framed fresh. Larkspur sees this work on hillside additions and whole-home remodels where owners want larger glass, specific sightlines toward Mount Tamalpais, or modern frame materials that old openings can’t accommodate. The rough opening has to be flashed and sealed correctly from the start, because Larkspur’s fog and winter rain find any gap. We work directly with the framing crew and the owner to keep the schedule tight. Window Installation in Larkspur details what we install and how the process runs.
Patio Door Installation in Larkspur
Patio doors in Larkspur take particular abuse from the marine air, and a poorly sealed door leaks heat and lets moisture into the wall. We install sliding, French, and multi-slide doors, and we’re careful about the threshold detail on Larkspur’s older homes where door openings were framed to different standards. If a door is being widened or relocated, that triggers a permit and often a structural header change. We handle that as part of the written quote. Patio Door Installation in Larkspur shows typical options and pricing for this market.

FAQs About Window Company in Larkspur
Most direct replacements, where the opening size and style don’t change, don’t require a permit. But if you’re widening an opening, adding a new window, or changing a door footprint, Larkspur may require a permit and design review. We check that before quoting and pull permits when the job calls for them. Call (817) 686-2228 to confirm for your specific property.
A standard same-size replacement of 5 to 8 windows usually takes one to two days once the units are on hand. Custom orders add two to four weeks for manufacturing. Larger projects with multiple second-story openings or new construction trim can run longer, and we cover the timeline in the written estimate.
