Fast, Reliable Door Replacement Across Inverness
Most door replacement in Inverness runs between $1,800 and $4,600 for a standard exterior door, installed. That range covers a quality pre-hung fiberglass or steel unit with hardware, weather sealing, and proper flashing. If you’re replacing a sliding glass door or an entry system with sidelights, expect to start around $3,200 and go up from there. Call (682) 281-2168 for a written line-item price before any work starts, no estimate guessing games.
We know Inverness homes. We know the salt air off Tomales Bay eats at door frames faster than almost anywhere else in Marin. We know afternoon winds whip up Sir Francis Drake Boulevard and find every gap in old weatherstripping. And we know that a door that looks fine from the inside is often quietly failing at the threshold or along the jamb. Our crews serve Inverness directly, and we answer the phone 24/7 with a live person who knows this area.
Why Juniper Windows & Doors Is Inverness’s Preferred Door Replacement Company
We’re a windows-and-doors specialist, not a general contractor who happens to hang a door between kitchen remodels. That narrow focus matters here, because Inverness sits in a unique code overlap: high wind exposure and wildfire hazard. Our installers work with Class A fire-rated assemblies and wind-rated glass daily, and we stock the hardware and flashing details that Marin County inspectors look for on door replacements.
Every job gets a written price before the work begins. No vague estimate, no surprise invoice at the end. If the work isn’t done right, our 365-Day Done Right Promise covers it, parts and labor, in writing. That’s how Sean Mackey runs every Inverness project. Homeowners in Inverness Park, on the ridge above town, and along the bay all get the same standard: background-checked, uniformed technicians, a live arrival time, and before-and-after photo updates.
Our Inverness customers regularly note two things in reviews: the door arrived when we said it would, and the price never changed. We don’t think that should be exceptional. It’s just how door replacement should work.
Door Installers in Inverness
Door Installers in Inverness handle the physical work of removing an old door, preparing the rough opening, and setting a new pre-hung or slab unit so it operates cleanly and seals tight against coastal wind and rain. A direct swap for a standard 36-inch entry door in Inverness typically runs $1,800 to $3,000 including the door, hardware, trim, and haul-away of the old unit.
Pre-Hung Door Installation
This is the most common project we do in Inverness. The entire frame, hinges, threshold, and door arrive as one unit. We level and square the frame, insulate the gap between the jamb and rough opening, flash the exterior to shed water, and seal the interior. For older Inverness homes with settled framing, a pre-hung door is almost always the better call than trying to fit a new slab into an out-of-square opening.
Sliding and French Door Replacement
Homes along the bay and up the Inverness Ridge often have sliding glass doors that take a beating from salt air and wind. Replacing a sliding patio door in Inverness typically runs $3,200 to $5,800 depending on glass package and fire-rating requirements. We install doors with laminated interlayers that hold glass in place if an ember strike or windborne debris hits.
Door Contractors in Inverness
Door Contractors in Inverness manage the full scope of a door replacement project: measuring, ordering the right unit, pulling or coordinating permits, handling lead-safe practices on older homes, scheduling installation, and passing final inspection. Our contract pricing for a standard exterior door replacement with permit coordination lands between $2,200 and $3,900 depending on the door material and any structural correction the opening needs.
Permit Coordination and Code Compliance
Exterior door replacements in unincorporated Marin County generally require a building permit, especially when the door is in a fire-rated wall assembly or when the rough opening changes. We handle the permit paperwork. Sean Mackey’s team knows what Inverness inspectors flag most: improper flashing, missing ember seals at the threshold, and doors without the required wind pressure rating.
Structural Correction on Older Inverness Homes
Many Inverness homes were built in the 1960s and 1970s with untreated wood and minimal shear detailing around door openings. When we pull an old door, we often find rot at the sill or a header that has sagged a quarter inch. We correct those issues before the new door goes in, so you’re not paying for a replacement that fails in three years. That structural work is priced in writing before we touch the opening.
Trusted Brands We Service in Inverness
We install and service Therma-Tru, ViewLux, PGT, and CGI door products, and we stock the seals, sweeps, and hardware that match these lines for quick turnaround on Inverness jobs. Door Replacement is our core specialty, and we carry enough product knowledge across these four brands to match the right door to a coastal wildfire zone without compromise. If you have an existing PGT or ViewLux door that’s failing, we can source the exact replacement parts rather than forcing you into a full replacement.
Common Door Replacement Problems We See in Inverness Homes
- Salt-air corrosion on hinges and thresholds. Homes within a mile of Tomales Bay get constant marine exposure. Aluminum thresholds and steel hinges pit and seize. We replace them with corrosion-resistant hardware that holds up within a half mile of the water.
- Wind-driven water penetration around old weatherstripping. Afternoon winds off the Pacific push 40 to 60 mph gusts through the Inverness Gap in late spring. Old door seals deflect, and then water rides the wind right into the house. We test and replace compression seals on every install.
- Ember intrusion at the door sweep. Wildfire is the defining risk for Inverness homes on the ridge and in the forested draws. Gaps at the bottom of an exterior door are ember entry points. We install ember-resistant sweeps and threshold details that meet Class A assembly requirements.
- Rotted wooden door frames on 1970s-era homes. Many Inverness homes along Balboa Avenue and the side streets off Sir Francis Drake Boulevard were built with wood jambs sitting directly on concrete slabs. Forty years of fog drip rots the base of the jamb. We cut out the rot and set new framing before the door goes in.

FAQs About Door Replacement in Inverness
Yes, in most cases. Unincorporated Marin County treats exterior door replacement as a structural change, particularly when it involves a fire-rated wall or changes to the rough opening. We pull the permit, schedule the inspection, and make sure the door passes on the first visit. Call (682) 281-2168 and we’ll tell you upfront whether your specific project needs one.
A Class A fire-rated fiberglass or steel door with a laminated glass interlayer and ember-resistant seals is the right choice for most Inverness homes. Fiberglass holds up better than steel against salt air, which is why we typically recommend a Therma-Tru or PGT fiberglass unit with the fire rating. For exact pricing on a fire-rated door for your home, call (682) 281-2168.
A standard exterior door replacement takes one day from removal to final trim and hardware. If we find rotted framing or need to correct a sagging header, expect a second day for structural work. Permit inspection is typically scheduled within one to two weeks after installation. We’ll give you a written calendar before work starts.
In some Inverness homes we can replace just the slab if the existing frame is square, rot-free, and structurally sound. In older homes near the bay or on the ridge, the frame is usually the problem, so a full pre-hung replacement makes more sense. We’ll assess honestly and price whatever works, we won’t sell you a full replacement if a slab will do the job. Call (682) 281-2168 for a free evaluation.
We install Therma-Tru, ViewLux, PGT, and CGI doors, which gives us a strong range of fire-rated, wind-rated, and coastal-hardware options. Within the Relay Home Co. family, we have access to eight product lines, so the right door for an Inverness home is never a compromise. We’ll recommend the brand and model that fits your exposure and budget, with the price in writing before we order.
Because Inverness sits in a high-wind, wildfire-prone coastal zone, door replacement here often requires Class A fire-rated assemblies and ember-resistant details alongside wind pressure ratings. This dual requirement is rare in the Bay Area and shapes every product and installation decision. We recently replaced a failing sliding glass door in a 1970s home on Balboa Avenue in Inverness. The original door had corroded frames and single-pane glass that shattered during a windstorm. We installed a new Therma-Tru fiberglass door with a laminated glass interlayer and a Class A fire rating, meeting both wind and wildfire codes. The homeowner appreciated the improved security and energy efficiency.
If your Inverness door is sticking, leaking, corroded, or no longer closing tight against the wind, call (682) 281-2168. We’ll give you a written quote, a realistic installation date, and a door that meets Marin County’s wildfire and wind codes. Free estimates, no change orders, and a full year of coverage if anything isn’t right.
