Window Company in Larkspur, CA
Meridian Windows & Doors is a window company serving Larkspur, CA with window replacement, window installation, and patio door installation pulled from eight manufacturer lines. Most homeowners here call us after years of fighting drafty single-pane wood sashes or a patio door that sticks in winter and swells in fog season. Larkspur’s mix of historic Craftsman bungalows, 1950s ranchers, and steep hillside contemporaries means nearly every job involves custom sizing, careful flashing, and an honest conversation about what the original builder got right and wrong. Call (831) 273-7126 to schedule a free estimate.
Why Larkspur Homes Are Different
Larkspur sits at the base of Mount Tamalpais, and every window and door you install here has to answer for that geography. Heavy winter rain, daily fog, and the occasional freeze-thaw cycle means flashing and sealing do more work than they would in flatland Marin towns like San Rafael or Novato. Homes on the steep oak-covered lots above downtown Larkspur, especially in the Madrone Canyon and Palm Hill areas, catch stronger wind uplift than homes near Sir Francis Drake Boulevard, so a window that holds fine at street level can pull moisture through the frame upslope.
The housing stock compounds it. Many of Larkspur’s early-1900s Craftsman bungalows still have original double-hung wood sashes with sash cords that have rotted clean through from decades of coastal moisture. The 1950s and 60s ranchers are typically single-pane aluminum or wood, and the 1970s hillside contemporaries often have large fixed glass panels that were never flashed properly to begin with. Hillside doors shift with soil creep, which is why we set adjustable thresholds and square the rough opening rather than trusting the old framing. It’s not a harder job in Larkspur, but it is a different job, and the wrong assumptions will show up in a leak within two winters.
Our Main Larkspur Services
Larkspur homeowners most often call us for replacement of failed wood-sash windows and installation of new patio doors that open onto decks and hillside gardens. Each service has its own Larkspur page with local pricing and job detail.
Window Replacement in Larkspur
Replacing a window in Larkspur usually means matching the look of an old Craftsman exterior while upgrading the glass to something that can handle wet winters and summer heat spikes. We measure every opening, not the existing sash, and we spec low-E glass (a thin coating that reflects heat while letting light through) where the exposure calls for it. Older homes on Baltimore Canyon and Madrone Canyon lots often have out-of-square openings, so a custom-sized replacement is the difference between a clean install and a frame full of shims and caulk. See how Window Replacement in Larkspur is priced and scheduled.
Window Installation in Larkspur
New-construction and full-tear-out window installation in Larkspur has to satisfy both the hillside structural rules and the reality of moisture coming off the mountain. We pull the old frame, inspect the rough opening for rot, and flash before and after the new unit goes in. On 1970s hillside contemporaries with large fixed glass, we check the header and king studs because decades of wind and damp can compromise framing that looked solid when the house went up. Details on Window Installation in Larkspur, including what we do before the first screw goes in.
Patio Door Installation in Larkspur
Larkspur patio doors take a beating. Hillside soil creep shifts the rough opening over time, and a door that was square twenty years ago probably is not square now. We install patio doors with adjustable thresholds and re-square the rough opening as part of the job, because no weatherstrip can compensate for a frame that has moved. Homes on the flatter lanes near downtown face less of this, but the rain and fog still demand robust sill pan flashing. Full scope and pricing on the Patio Door Installation in Larkspur page.

FAQs About Window Company in Larkspur
It depends on the scope. Larkspur enforces hillside structural and wildfire safety codes, so a like-for-like replacement may not need a permit, but any reframing or opening enlargement generally does. We determine that during the estimate, and if a permit is required, we pull it and schedule the inspection as part of the job. The permit and inspection cost is on the written estimate, not added later.
