Fast, Reliable Door Installation Across Larkspur
Door installation in Larkspur runs $900 to $4,800 for most entry doors and $2,200 to $9,500 for multi-panel French or bifold units, and the work usually takes one to two days once the old door is out and we can see the framing. We say “once we can see the framing” because Baltimore Canyon and the older streets off Magnolia Avenue have a way of hiding rot behind the jamb that changes the scope of the job. Our crews work in Larkspur every week, so scheduling is straightforward and we show up familiar with the houses, the hills, and the microclimates that make doors fail here. Call (888) 635-0804 and a live person answers, day or night.
Why TruePane Windows & Doors Is Larkspur’s Preferred Door Installation Company
We have spent years working on homes like the ones that line Magnolia Avenue and climb into the hills above downtown Larkspur. These are not tract houses with uniform rough openings. They are Craftsman bungalows and Victorian cottages with settled framing, hand-trimmed jambs, and door openings that were never square to begin with. Our technicians measure every opening twice and quote manufacturer lines side by side on paper, so the homeowner sees exactly what goes into the number before work begins.
Dale Kessler founded TruePane on a rule he still keeps on the whiteboard in the shop: if the pane is not true, the job is not done. That standard applies to the hinges, jamb, threshold, and flashing on every Larkspur door we hang. We are not the cheapest bid in town. We are the last call a homeowner needs to make, backed by The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, and a Done Right Promise on every job. Dispatch is coordinated from our San Francisco Bay Area office, and crews serve Larkspur locally.
Our Larkspur customers tend to have lived in their houses for twenty years or more. They remember the contractor who left a door that binds in July. They know what a failed seal looks like. They call us because we write the warranty registration in the driveway, before the truck leaves, and we answer the phone when they call back.
Our Door Installation Services in Larkspur
Entry & Swing Doors
Entry doors in Larkspur do heavy work. They face wet fog mornings off the Corte Madera Creek valley, afternoon sun on the west-facing hillsides, and decades of settling on the older streets around downtown. We install entry doors that close square and latch on the first try, with thresholds that drain water away instead of holding it against the sill. For hillside homes in the Wildland-Urban Interface zones, we handle fire-rated entry units with non-combustible frames and proper seals, so the permit inspection passes without a re-do.

French & Double Doors
French doors on a Larkspur Victorian or Colonial Revival need more than a stock unit dropped into an old opening. The jambs have usually absorbed decades of fog moisture, and the rough opening drifts out of plumb as the foundation settles. We reframe or sister studs where needed, rebuild the threshold to shed water, then hang both panels so they meet clean in the center without dragging. Homeowners on Baltimore Canyon properties often ask for fire-rated glass here too, and we quote PGT, CGI, and CWS units side by side on paper.

Arched & Custom Doors
Larkspur’s older homes frequently have arched openings or non-standard sizes that no off-the-shelf door will fit. The stock answer from a lot of installers is to square off the opening and call it done. That erases the streetscape character. We measure the actual arch radius, build or order to spec, and keep the original trim profile intact. If the jamb is original fir with a hundred years of paint on it, we match the detail rather than replacing it with flat stock.

Bifold & Pivot Doors
Bifold doors work well in Larkspur homes where a dining room or den opens to a deck or canyon view. The catch is that humidity from the creek valley swells wood and causes rollers to bind. We set bifold tracks with enough tolerance to handle Larkspur’s seasonal moisture swings, and we flash the opening so water never gets behind the track. Pivot doors, which are heavier and carry more leaf load, get reinforced headers and heavy-duty pivot hardware so the door swings true years after install.
Every installation starts with a free on-site measure and a written line-item quote. No allowances hidden in fuzzy language. If we find rot, we photograph it, explain it, and price the repair in writing before we touch it. That is the standard on our Door Installation work across the Bay Area, and it is how we handle every Larkspur job.

Trusted Brands We Service in Larkspur
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. For Larkspur homes, we commonly quote PGT and CGI for fire-rated hillside doors, plus CWS where a custom arch or odd rough opening calls for a built-to-spec unit. Because we register both warranty layers in writing and stock common hardware and weatherseal locally, Larkspur customers get faster turnaround on parts and no argument when a manufacturer claim comes up. We hand you the paper with the warranty term and coverage written on it, not buried in a link.
Common Door Installation Problems We See in Larkspur Homes
- Rotted king studs and sill plates from failed flashing tape. The Baltimore Canyon canopy keeps door frames shaded and damp for days after a storm. Water tracks behind the siding, the framing wicks it, and by the time the door sags or binds, the wood behind the jamb is often soft to the screwdriver. A half-day slab swap becomes a structural repair.
- Swollen, split jambs on pre-WWII Craftsman and Victorian homes. Decades of marine fog and fog-driven condensation have done what water does to wood. The rough opening is no longer square or plumb, so a factory swing door will not latch without planing, shimming, or full jamb replacement.
- Corroded hardware and sagging doors from damp canyon air. Older single-pane doors with failed glazing putty and flattened weatherstripping let foggy air condense on interior hinges and handles. The bottom rail starts to rot, and the door drops until it scrapes the threshold.
- Code triggers on hillside and WUI-designated properties. Replacing an entry or side door on a Larkspur hillside home often triggers a fire-rated glazing or non-combustible frame requirement under current California building code. We know the paperwork and the product lines that meet it, so the permit closes without back-and-forth.

FAQs - Door Installation in Larkspur
Because the redwood canopy in Baltimore Canyon blocks direct sun so completely that exterior door frames stay wet for days after a storm, and water that never dries out eventually rots the king studs and rough sill plate behind the jamb. Failed flashing tape is the usual path for the water. What starts as a routine door swap turns into a framing repair more often in Baltimore Canyon than almost anywhere else in Marin. Call (888) 635-0804 and we will inspect before we quote, so you know the real scope and the real number.
Many hillside neighborhoods above downtown Larkspur fall within California’s Wildland-Urban Interface fire hazard designation, and code requires fire-rated glazing and non-combustible frames on new door installations there. We quote PGT and CGI fire-rated units side by side on paper so you can see exactly what the compliance piece costs. If your property is in a WUI zone, we will tell you during the on-site measure and include the correct products in the written quote. Call (888) 635-0804 for a free estimate.
Yes, in most cases we match the profile using custom milled trim rather than off-the-shelf flat stock, and we do it without making the job feel like a museum piece. We measure the existing casing and architrave profiles, mill or order matching stock, and install the new door so the streetscape character stays intact. Call (888) 635-0804 to schedule a measure and we will tell you what can be matched and what should be replaced.
Fog between the panes is a failed insulated glass seal, and Larkspur’s fog-driven condensation cycles fail seals faster than drier inland climates. Once the desiccant inside the glass unit is saturated, the unit cannot be repaired, only replaced. We register both manufacturer warranty layers in writing, so if a seal fails within the stated term, the replacement is covered. Call (888) 635-0804 and a live person will walk you through the warranty claim process.
We photograph it, explain it in plain language, show you the soft wood and the water path, and price the repair in writing before we touch it. The contract includes a framing allowance so you are not hit with a surprise change order. Recently, our crew pulled a rotted entry door on a Craftsman bungalow near Magnolia Avenue in Baltimore Canyon, expecting a straightforward slab replacement. Once the old jamb was out, both king studs were soft to the screwdriver and the rough sill plate was crumbling. We sistered new pressure-treated studs, reframed the rough opening to true dimensions for a custom Andersen entry unit, installed a fire-rated low-E glass door with argon fill and a fusion-welded frame, then wrapped the opening in fresh self-adhered flashing. The job took two extra days. The homeowner approved every part of it before we cut anything. That is how we work in Larkspur.
Call (888) 635-0804 to schedule your free door installation estimate in Larkspur. A live person answers 24 hours a day, 7 days a week. We are background-checked, uniformed, and we stand behind every door we hang. If the opening is not square and the door is not true, the job is not done.
