Door Replacement in Larkspur - Free In-Home Measure, Written Price

Fast, Reliable Door Replacement Across Larkspur

Replacing an exterior door in Larkspur typically costs between $1,800 and $5,400 for a standard single entry door installed, and most projects are completed in one to two days once the door arrives. That range covers the door slab, hardware, labor, and permits where required. If you’re on Magnolia Avenue or up in the Madrone Avenue hills, the number that matters more than anything else right now is whether your existing jamb can take a new door without reframing. Call us at (682) 281-2168 and we’ll walk through what your specific doorway actually needs before you spend a dollar.

Larkspur homes are a mix of 1950s ranchers, hillside contemporaries, and Historic District-adjacent cottages. That means door openings come in different sizes, different states of square, and different permitting situations depending on your street. We measure first, quote second, and never start demolition on a guess.

Why Juniper Windows & Doors Is Larkspur’s Preferred Door Replacement Company

Larkspur homeowners keep calling us back because we do the unglamorous work correctly: measuring the rough opening, checking jamb depth, confirming the swing, and pulling the right permit before the old door ever comes off its hinges. Our Door Replacement team has handled entry doors on everything from compact downtown bungalows near Sir Francis Drake Boulevard to larger hillside properties above Escalle Winery, and the local quirks are always the same: older jambs, settled thresholds, and west-facing entries that bake in the afternoon sun.

Every Larkspur job runs through the same system. You get a written price before we order anything. You get a live arrival time you can track. You get before-and-after photos of the entry, and you pay from a digital invoice. Sean Mackey has built this standard into every project since the first day. If the work isn’t right, the 365-Day Done Right Promise covers parts and labor for a full year, in writing. A second visit to correct a repair failure? Free. No charge. No argument.

Our crews are background-checked and uniformed. When the installer rings the bell on a Larkspur street, you know exactly who is walking up the path. And if you call after hours with a question, a live person answers. Every time. That’s the Relay Visibility Guarantee, and it applies to every project we book.

Door Installers in Larkspur

Door Installers in Larkspur typically come into play when a homeowner wants a new entry system, a sidelight configuration changed, or a patio slider swapped for something tighter and better sealed. The job involves removing the old door and frame, inspecting the rough opening, squaring the jamb where needed, fitting the new prehung unit or slab, insulating around the frame, sealing the sill pan, and re-casing the interior trim. Expect most single-door installs in Larkspur to run $1,800 to $5,400 including materials and labor, with higher-end impact-rated or custom sightline doors pushing toward $4,800 to $7,200 when the lintel and framing need reinforcement.

Timing matters more in Larkspur than people expect. If your entry faces west toward Mount Tamalpais, an installer needs to account for serious afternoon heat and UV exposure on the finish and weatherstripping. We spec glazing and seals for that orientation, not the generic default.

Entry Door Installation on Historic District Homes

If your Larkspur home sits within the Historic District review boundary, a street-facing entry door is not automatically a simple swap. The city’s design review can require the style, panel profile, and finish to remain compatible with the home’s original character before a permit gets issued. We handle that paperwork sequence and can supply a Therma-Tru door with a traditional raised-panel look that satisfies review without sacrificing modern weather performance.

Sidelight and Transom Upgrades

Many Larkspur entryways from the 1960s and 1970s have narrow, inefficient sidelights that leak air at the seams. Replacing the entire system, sidelights included, fixes the thermal break and modernizes the sightline. We measure the full rough opening width, not just the door, so the new unit fits without expanding the opening and triggering unplanned reframing costs.

Door Contractors in Larkspur

Door Contractors in Larkspur handle the structural side of the job: checking whether the header and king studs are sound, whether adding a wider door means a new lintel, and whether the subfloor beneath the threshold has been quietly rotting behind old caulk. Without that check, you end up with a beautiful new door leaking at the base by January. A straightforward contractor-led replacement in Larkspur runs $3,200 to $6,800 when it includes jamb surgery and new sill flashing, and the contractor’s permit number goes on the job card.

Sean Mackey’s crews pull permits and schedule inspections on every Larkspur project that requires them. Final inspection passed with no corrections is the normal outcome, not the hope. If you’re swapping like-for-like with no width change on a backyard door, Larkspur often does not require a permit, but our team confirms that before you pay anything.

Structural Openings and Jamb Repair

On older Larkspur ranches, the door jamb often isn’t square by a quarter inch or more, especially after forty years of seismic settling. Forcing a new prehung unit into that opening means binding, gaps, and a door that won’t latch in winter. We plane, shim, and re-square the rough opening before the new frame goes in. The work costs an extra $400 to $900 in labor depending on how far out the opening has drifted, but skipping it means a door that will never hang right.

Threshold and Sill Pan Replacement

Larkspur’s wet winters expose a failed threshold fast. If the old sill pan is rotted or missing, water wicking under the new door will rot the subfloor inside two seasons. Our standard is a continuous PVC sill pan with integrated end dams and back dam, flashed to the sheathing before the door is set. It adds $200 to $500 in materials and is the difference between an entry that lasts fifteen years and one that fails in three.

Trusted Brands We Service in Larkspur

We install and service doors from PGT, Therma-Tru, and ViewLux, and we maintain access to CGI, CWS, ES Windows, ECO Window Systems, and Mr-Glass through our full product network. What that means for a Larkspur homeowner is simple: if you already have a PGT impact-rated door that’s ten years old and the hinges are sagging, we stock the replacement hardware and can get the panel ordered without a four-week scavenger hunt. If you want a Therma-Tru fiberglass entry with a traditional profile for a Historic District review, we’ve installed that exact configuration on this side of Marin County more times than we can count.

Common Door Replacement Problems We See in Larkspur Homes

• Out-of-square rough openings on older ranches. Larkspur’s post-war ranch homes have settled unevenly for decades, and the door opening rarely matches the manufacturer’s spec sheet. We measure rough opening dimensions, floor level, and jamb depth before ordering a single component.
• West-facing entries with heat and sun damage. Homes on the west-facing slopes above downtown Larkspur get hard afternoon exposure, which warps hollow-core doors and degrades weatherstripping. We spec laminated or low-E insulated glass units and UV-stable seals for those exposures.
• Historic District review stalls. A street-facing door replacement near the downtown core may need design review before a permit is issued. We submit the spec sheet, panel profile, and finish samples early so the project doesn’t sit idle at the permit desk.
• Rotted thresholds and missing sill pans. Years of Larkspur rain against a poorly flashed entry rot the subfloor beneath the threshold. The new door looks fine for the first season, then leaks at the base when the storms return. We replace the sill pan as standard practice, not as an upsell.
