Interior door replacement lands between $400 and $1,200 per door, frame work included when needed. Salty fog off the Pacific decides what survives out here, and we spec every install accordingly. If your door is sticking, rusting at the bottom rail, or no longer latching clean, call Juniper Windows & Doors at (682) 281-2168 and we’ll give you a written price before a single screw comes out.
Why Juniper Windows & Doors Is Half Moon Bay’s Preferred Door Replacement Company
We’ve worked on enough homes along Highway 1, in the Highlands, and over near Frenchmans Creek to know what the marine layer does to a door. Zinc-plated hinges pit. Steel slabs rust through at the seam. Wood jambs swell in the fog and throw the latch out of alignment. When a Half Moon Bay homeowner calls us, the person who answers has likely seen their exact failure mode before.
Every project gets a written price before work begins. You’ll know the number, the scope, and the materials, and that number does not change unless you change the scope. Sean Mackey leads the team, and the standard he enforces is the same on every job: background-checked, uniformed technicians, a live arrival time you can track, before-and-after photos, and a digital invoice you can pay from your phone.
The 365-Day Done Right Promise covers parts and labor for a full year. If something isn’t right, we make it right. Free second visit, no charge, no argument. That’s not marketing language; it’s in writing on every project we do from El Granada to the Ritz-Carlton side of town.
Door Frame Repair in Half Moon Bay
Door frame repair in Half Moon Bay typically becomes necessary when a jamb has wicked moisture from the marine air and swollen enough to throw the door out of square. We see it constantly in older beach cottages and 1970s-era homes along the coast, where the original lumber was never sealed for salt exposure. The job involves pulling the casing, cutting out rotted sections, sistering in new treated or composite stock, re-shimming the jamb to square, and re-hanging the door so the latch and deadbolt align cleanly. Expect to spend between $750 and $1,800 for a standard single-door frame repair, depending on how far the rot has traveled.
Composite Jamb Upgrades
For homes within a mile of the water, we often recommend replacing a wood jamb with a composite jamb rather than patching it. Composite does not wick moisture the way wood does, and it will not swell in the fog cycle. The cost difference is modest, usually $150 to $250 more than a wood repair, and it pays for itself the first time a winter storm blows rain sideways against the entry.
Threshold and Sill Plate Repair
A corroded aluminum threshold is usually the first thing to go, and it is often accompanied by water damage under the sill plate. We see subfloor rot directly beneath entry doors in Half Moon Bay homes where the original threshold was never replaced. In heavy cases, the fix requires pulling the door entirely, cutting back the subfloor, and installing a hot-dip galvanized threshold with new flashing and marine-grade sealant.
Interior Door Replacement in Half Moon Bay
Interior door replacement in Half Moon Bay usually comes down to one of two things: the house is older and the hollow-core slabs have warped from decades of humid air moving through the home, or a homeowner is updating bedrooms and hallways and wants real panel doors instead of builder-grade flats. We install solid-core, shaker, and glass-panel interior doors, pre-hung or slab-only depending on what the existing jambs can support.
Solid-core interior doors also help with the sound bleed common in Half Moon Bay’s dense coastal neighborhoods, where homes sit close together and a bedroom facing a shared fence picks up the neighbor’s weeknight noise. A pre-hung solid-core door, installed, runs $400 to $800. A glass-panel interior door is $600 to $1,200, depending on glass type and frame stock.
Humidity and Hollow-Core Distress
Hollow-core doors near the coast absorb moisture unevenly because the air inside a home swings from damp to dry as fog burns off and furnaces run. The slab bows, the edges swell, and the door starts catching on the frame. Homeowners near Pillar Point and over in Alsace Lorraine tell us the same story: the door rubs at the top in summer, then slams fine all winter.
We handle humidity-stable options with sealed edges and solid cores that resist the warping pattern hollow doors fall into after years of salt air cycling through the house.
Trusted Brands We Service in Half Moon Bay
We have access to eight product lines, and for coastal installs we most often specify Therma-Tru fiberglass entry systems, plus hardware-rated packages built around marine environments. We service and install doors from CGI, CWS, and ES Windows where the project calls for impact-rated glazing or specific sightlines. Since we carry parts and hardware common to these brands, we don’t mail-order hinges and wait. We stock stainless and hot-dip galvanized options locally for Half Moon Bay customers, which keeps replacement turnarounds short when a salt-damaged hinge or threshold needs to be swapped.
Common Door Replacement Problems We See in Half Moon Bay Homes
- Rusted-through steel slabs. We removed a rear entry door near Poplar Beach recently where the original steel slab had rusted clean through at the bottom rail. Salt fog condensed on the door face every morning, and the factory weep holes were sealed with paint. The slab was holding water like a bucket.
- Swollen jambs that kill the deadbolt. When a wood jamb absorbs moisture from marine air, it expands against the slab and pushes the latch out of alignment. The deadbolt no longer lines up with the strike plate, and the door either won’t lock or won’t open without shoulder pressure.
- Corroded thresholds and hidden subfloor rot. The threshold takes the most direct abuse from wind-driven rain and salt spray. Once the aluminum pitting starts and the caulk joint fails, water wicks under the sill plate and rots the subfloor from below. By the time the door feels soft underfoot, the damage is already there.
- Fogged and failed glazing in entry doors. Decorative door glass on the fog belt side of Half Moon Bay takes constant moisture. Failed seals show up as interior condensation between panes, which is permanent. The fix is replacing the glass insert or the entire door slab, depending on the frame.
Pricing for Door Replacement in Half Moon Bay, CA
A basic interior door slab, installed, runs $400 to $1,200 depending on core type and hardware. A standard exterior steel or fiberglass entry door replacement in Half Moon Bay runs $1,900 to $3,800. Add impact-rated glazing, a composite jamb package, a new hot-dip galvanized threshold, or sidelites, and the number moves toward $5,600 or more on the high end. The labor here is the same labor you’d pay anywhere else; what moves the price is the coastal-spec hardware and the material choices that survive the salt.

FAQs About Door Replacement in Half Moon Bay
Because the salt-laden fog condenses on exterior door faces, hinges, and hardware, then the moisture evaporates and leaves salt behind. That salt sits on steel and zinc-plated hardware and accelerates corrosion dramatically. The failure pattern is rust from the outside in, rather than the heat-and-dry-rot pattern you see inland in places like Concord or Livermore. We specify stainless or hot-dip galvanized hardware and marine-grade sealants for a reason. To get a door that actually lasts, call (682) 281-2168 and we’ll walk you through the spec.
Fiberglass, with a composite jamb, stainless hinges, and a hot-dip galvanized threshold. Therma-Tru fiberglass slabs don’t rust and don’t absorb moisture the way steel or wood do, so the fog belt does not degrade the slab itself. The hardware is the next failure point, which is why we spec it marine-grade from the start. Steel and wood can work, but they require a maintenance cycle most homeowners don’t want to keep up with in a salt-fog environment.
If the jamb is square and dry, you can replace just the slab. If the jamb has swelled, rotted, or been drilled multiple times for different hardware, you need a frame replacement or at minimum a jamb repair. We see both situations in Half Moon Bay; the frame decision comes down to moisture damage, not preference. We’ll tell you which one you actually need when we inspect the door, and we’ll show you the written price for either option before you commit.
The materials cost more. Stainless and hot-dip galvanized hardware runs $80 to $180 more per door than standard zinc-plated hardware. A composite jamb and brickmold package adds $150 to $250. Marine-grade caulk is $12 to $20 per tube versus $5 for standard latex. The labor is nearly identical; the delta is the hardware and sealant package. That package, installed once, is the difference between a door that goes 15 years and a door that looks shot in three. The cheap spec costs more within a decade because you buy it twice.
Yes. We can build an entry door with impact-rated glass from CGI, CWS, or ES Windows, and we can pair it with low-E coatings that cut the heat gain from the afternoon sun off the water. Impact-rated glass is built to resist wind-borne debris without shattering, which matters when winter storms roll off Mavericks and push wind up against west-facing entries. For an exact quote on a glazed entry door, call (682) 281-2168; estimates are free and the price is written before anything starts.
