Fast, Reliable Door Replacement Across Sausalito
Door replacement in Sausalito typically runs $900 – $4,800 depending on whether we’re hanging a new slab on an existing frame or cutting out and rebuilding the entire rough opening, and most jobs here take one to two days once materials arrive. If you live on the hillside streets east of Bridgeway or in the banana-belt slopes above downtown, your door has been fighting salt fog, lateral rain, and marine-layer moisture since the day it was installed. We coordinate every Sausalito project from our San Francisco Bay Area office, and our crews know exactly what a 1950s shingle-sided cottage on Caledonia or a mid-century split-level off Alexander Avenue needs that a generic door company will miss. Call (682) 281-2168 for a written quote before any work starts.
Why Juniper Windows & Doors Is Sausalito’s Preferred Door Replacement Company
Sausalito homeowners don’t have much patience for a contractor who quotes vaguely and adjusts the number at the door.

No callbacks into a voicemail maze either, because our phones are answered by a real person 24/7.
Sean Mackey leads our team, and the standard he set is simple: background-checked, uniformed technicians on every job, a live arrival time you can track, before-and-after photos, and a digital invoice you can pay from a link. That’s the Relay Visibility Guarantee, and it’s how every Door Replacement project in Sausalito runs, from a front entry swap on Bridgeway to a rear deck door above the bay.
Door Frame Repair in Sausalito
Door frame repair in Sausalito is what saves a door that looks ruined but is actually fine, because the problem is in the jamb and sub-sill, not the slab. On the bay-facing side of a house, salt fog and sideways rain wick into untreated wood jambs within a few seasons. The frame swells, rots at the bottom corners, and the door starts dragging across the threshold. When we see that, we don’t just plane the door down. We cut out the failed wood, sister in pressure-treated stock, and reset the unit so it latches cleanly.
Rot and Sub-Sill Replacement
A homeowner on a hillside street above Bridgeway called us because their rear door wouldn’t close without a hip check. The slab looked okay. The frame was gone. We pulled the casing to expose the rough opening, found the sub-sill spongy from years of marine moisture, and replaced the whole bottom third of the frame with pressure-treated material. Expect Sausalito door frame repair to land between $500 and $1,400 depending on how much framing has to come out.
Re-Squaring Older Cottages
In the 1940s and 50s cottages that climb the slopes above downtown, the door opening itself is rarely square. Measuring off an out-of-plumb jamb instead of the rough opening and interior floor line produces a unit that binds against the strike, especially after a marine-layer humidity cycle swells the slab. We shim, plumb, and verify strike-side clearance before we call the frame done.
Interior Door Replacement in Sausalito
Interior door replacement in Sausalito usually means swapping hollow-core slabs for solid-core units that actually block sound between bedrooms, or replacing a hinge-bound door that hasn’t shut right since the hillside settled. Older Sausalito homes shift. Foundations on sloped lots move a fraction of an inch over decades, and suddenly an interior door that closed fine in 1980 rubs the jamb every time. A slab swap runs $350 – $850 per door, and a pre-hung interior unit with new casing and hardware runs $800 – $1,500 installed.
Solid-Core Upgrades for Noise
Homes on the banana-belt slopes are built tight against the street and against each other. A solid-core door cuts sound transmission noticeably compared to a hollow slab, and it changes how a hallway feels. We stock solid-core slabs and pre-hung ViewLux and Therma-Tru interior units, and we handle the trim, hinges, and hardware so the new door looks like it belongs in a house from 1958 or 1995 or 2021.
Historical Trim Matching
Sausalito has a real stock of older homes where the door trim is part of the charm, and owners don’t want a builder-grade replacement that erases it. We match the existing profile and finish, not just the width. When a client on a hillside lane above Caledonia wanted a new door without losing the original redwood casing, we kept the casing, replaced the slab and hardware, and the door looked like it had been there since the house was built.
Trusted Brands We Service in Sausalito
We’re set up to service the brands Sausalito homeowners already have, and to install the ones that make sense here. PGT and CGI impact-rated doors handle marine-layer moisture and wind-driven rain without warping. ViewLux gives us modern fiberglass and aluminum options with clean sightlines and low-E glass. Because we have access to eight product lines total, we don’t have to steer you toward a door that’s close enough; we quote the door that fits the opening, the exposure, and the WUI requirements if your parcel sits in a fire zone. Parts turn around fast because our dispatch runs from the Bay Area office.
Common Door Replacement Problems We See in Sausalito Homes
- Salt fog and lateral rain rot the bay-facing jamb first. The sub-sill under a deck door on the water side of the house fails within a few seasons if it wasn’t upgraded to composite or pressure-treated stock. A like-for-like swap just rots again.
- WUI fire-hardening requirements on hillside parcels. Exterior doors into garages and onto decks in the Wildland-Urban Interface zone need non-combustible surrounds and ember-resistant thresholds. A quote without a WUI check can get flagged at inspection.
- Out-of-square rough openings in older cottages. The 1940s – 60s hillside homes shift. A unit measured off an out-of-plumb jamb binds at the strike and swells worse through the humidity cycle.
- Slabs dragging thresholds from moisture expansion. When the marine layer rolls in and the slab swells, a door that cleared fine in September drags in January. That’s a frame fix or a re-set, not just a hinge adjustment.
Pricing for Door Replacement in Sausalito, CA
A slab swap on an existing square frame in Sausalito runs $900 – $1,600.

Interior slab swaps run $350 – $850 per door, and pre-hung interior units run $800 – $1,500 installed. The two things that move the number most are how much framing has to come out and whether the parcel sits in a WUI fire zone that requires hardening details.

FAQs About Door Replacement in Sausalito
Yes, most Sausalito exterior door replacements that alter the rough opening or sit on a hillside parcel in a Wildland-Urban Interface fire zone require a permit and may trigger a fire-hardening inspection. A like-for-like slab swap on the same frame often doesn’t. We pull permits when they’re required and pass inspections before we call the job done. Call (682) 281-2168 and we’ll tell you up front whether your specific door triggers one.
Because the jamb and sub-sill on a bay-facing Sausalito door are usually the parts that failed, not the slab. Hanging a new slab on a rotted or out-of-plumb frame means the new door binds, drags, and fails again within a few seasons. A full frame replacement with pressure-treated or composite stock fixes the root cause. We’ll show you the rot before we quote the fix.
Yes, in most cases. If the frame is square and the slab is the only problem, we match the style, finish, and hardware and leave your trim and casing alone. That’s the most cost-effective door replacement Sausalito homeowners choose, and it starts around $900. Call (682) 281-2168 and we’ll tell you honestly whether your door is a slab swap or a full frame replacement before any work begins.
One to two days on site for a full exterior replacement, including rot repair and WUI hardening details if your parcel requires them. A slab swap on a square frame is usually done in a few hours. Material lead times in Sausalito run two to four weeks depending on the product line, and we’ll give you a written schedule with your written price.
If your parcel sits in one of the Wildland-Urban Interface fire zones on the hillside slopes east of Bridgeway, yes, expect ember-resistant thresholds and non-combustible surrounds at exterior doors. Energy requirements apply everywhere in Sausalito, and low-E insulated glass units meet them for the marine-layer climate. We quote to whatever your parcel requires, not to whatever is cheapest to install. Call (682) 281-2168 for an exact quote on your specific door and parcel.
