Sliding Door Replacement in Larkspur
Sliding door replacement in Larkspur usually means pulling a failed aluminum or wood slider out of an opening that has shifted over decades, then fitting a new unit that actually seals. On hillside homes near Madrone Canyon, Baltimore Canyon, and the Palm Hill area, we regularly find openings 1/4 to 3/8 inch out of square from soil creep. A standard slider forced into that opening will bind within a season and leak the first winter the rain drives off Mount Tamalpais.
Most replacements run $2,800 to $7,400 depending on door width, glass package, and frame material.
Re-shimming and Adjustable Thresholds
We do not hang a new door in a racked opening. We strip the old jamb, check the rough opening with a laser, and re-shim the frame with tapered shims until it reads square. Then we set an adjustable threshold so the door can be fine-tuned as the hillside settles further.
When a Larkspur Homeowner Needs Replacement
You need a replacement when the sash no longer glides, the weatherstripping has compressed to nothing, or you see daylight around the frame. On older Larkspur homes with original single-pane sliders, condensation between the panes and visible frame corrosion are the usual signs it’s time.
Sliding Door Installation in Larkspur
Sliding door installation in Larkspur covers new construction, room additions, and cases where we are cutting a new opening in an existing wall. That’s different work from replacement. The rough opening has to be framed, flashed, and sealed before the door ever arrives, and on a hillside home that means accounting for wind uplift against a west-facing wall and drainage behind the flashing.
New sliding door installation typically runs $3,400 to $8,200 for a standard opening, more if structural header work is required on a load-bearing wall.
New Openings on Hillside Homes
Cutting a new patio door opening in Larkspur means working with the building department on shear wall requirements and wildfire exterior codes. We coordinate that. Our Larkspur installs include flashing detail drawings and permit-ready submittals when the job requires them.
Glass Package Selection
Most Larkspur customers spec low-E glass (a thin coating that reflects heat while letting light through) and at least one tempered lite. For west-facing rooms that catch summer heat spikes, we often recommend a spectrally selective low-E that cuts solar gain without darkening the view.
Trusted Brands We Service in Larkspur
We install and replace patio doors from eight manufacturer lines, including PGT, Mr-Glass, and Therma-Tru. PGT carries the impact-rated sliders we spec for wildfire-adjacent lots and hillside structural code. Mr-Glass covers high-performance custom glazing when an architect calls for something specific. Therma-Tru gives us solid fiberglass options for Larkspur homes that need a door to handle moisture without warping. Because we are authorized across all these lines, we order parts direct and do not wait on a distributor that serves all of Marin.
Common Patio Door Installation Problems We See in Larkspur Homes
- Racked openings from soil creep. Hillside lots on Larkspur’s steep, oak-covered slopes shift over decades. A door installed square in 1985 is not square today. We re-shim and use adjustable thresholds instead of forcing a fit.
- Wind-driven rain intrusion. Winter storms off Mount Tamalpais push rain sideways. Poor flashing and unsealed sills leak within one season. We flash to drain and use a full sill pan on every install.
- Non-impact glazing on canyon-facing walls. Homes facing wildfire-prone canyons often need impact-rated glass with a laminated interlayer to meet current hillside codes. Standard glass can fail inspection.
- Solar heat gain on west-facing rooms. Standard clear glass in a west-facing Larkspur slider turns a living room into a greenhouse during summer heat spikes. The right low-E package fixes that without blackout tint.

FAQs About Patio Door Installation in Larkspur
We strip the old frame, measure the rough opening with a laser, and re-shim the jamb with tapered shims until the opening reads square before the new door goes in. Then we install an adjustable threshold. That’s standard practice on Larkspur hillside lots, and it’s the difference between a door that glides for years and one that binds by spring. Call (831) 273-7126 for a site check and a written price.
Maybe. Larkspur’s hillside structural codes apply to many lots outside the formal wildfire hazard zone, especially those facing canyon corridors. If your architect or building department calls for large-missile certification or impact certification compliance, you need an impact-rated door with a laminated interlayer. We will tell you what your specific address requires before you spend a dollar. Exact quote is free.
Low-E glass with a spectrally selective coating handles both. It blocks a meaningful share of solar heat in summer without turning the room dark, and it holds interior heat in winter. For west-facing rooms in Larkspur, we often pair that with argon fill between the panes. For canyon-facing walls, we add a laminated interlayer for impact resistance. Call (831) 273-7126 and we’ll walk you through the glass options for your exposure.
Yes. Larkspur’s early 1900s Craftsman bungalows and mid-century ranchers need more than a stock door dropped in. When the trim profile, casing, or threshold detail matters, we coordinate with a millwork shop that matches the original profile and grain. We also coordinate directly with architects and designers on those jobs. The millwork adds $600 to $1,800 to the quote, and that number is on paper before we order.
Impact-rated glass packages and custom widths are the two big ones. A PGT impact slider can take 8 to 14 weeks depending on the spec. Custom millwork-matched doors add 4 to 6 weeks. On a 1970s hillside contemporary off Madrone Canyon, our crew replaced a single-pane aluminum slider with a PGT impact-rated unit. The opening had shifted nearly 3/8 inch out of square from decades of soil creep, so we reframed the jamb with tapered shims and installed an adjustable threshold before hanging the new sash. That homeowner now gets a true seal against winter rain driven off Mount Tamalpais, and the door glides without binding. We tell you the lead time when we quote, and the price stays fixed while you wait. Call (831) 273-7126 to get your door on the schedule.
