Fast, Reliable Door Replacement Across San Bruno
Door replacement in San Bruno usually runs $1,200 to $4,800 for an exterior door with installation, and $450 to $2,200 for an interior slab or pre-hung unit, with most exterior jobs finished in one day once the door is ordered and on site. Those ranges cover the real spread we quote: a simple interior hollow-core swap on the flat grid near Crystal Springs Road lands at the low end, while a Therma-Tru fiberglass entry with low-E glass and new framing on the hills above Crestmoor Drive sits at the top. Led by Sean Mackey, our Door Replacement team measures the actual rough opening before we write a single number, because San Bruno homes rarely take a stock slab without some kind of jamb or header adjustment. Call (682) 281-2168 and we’ll scope your door, measure the framing, and put the real price in writing before anything gets ordered.
Why Juniper Windows & Doors Is San Bruno’s Preferred Door Replacement Company
San Bruno door work lives and dies on the details most contractors skip: the header depth on a 1940s bungalow, the jamb caulking on a fog-belt hillside, the threshold height where Pacific air pushes moisture sideways. We know those details because Sean Mackey and the crew are in this city’s neighborhoods every week, not dispatching from three counties over with a generic install checklist. Scheduling for San Bruno is coordinated from our San Francisco Bay Area office, and every job gets the Relay Visibility Guarantee: a live arrival time you can track, before-and-after photos, and a written price that doesn’t shift when the crew sees the actual framing.
The 365-Day Done Right Promise is in writing on every San Bruno project. If the door isn’t right in the first 365 days, we make it right, parts and labor included. That matters in a city with this much mixed housing stock, because a door that works on a 1960s tract home on the west side doesn’t always behave the same on a pre-war flat-grid house with a shallower header. We quote based on what your actual opening needs, not what a stock slab says it needs.
Interior Door Installation in San Bruno
Interior door installation in San Bruno means we measure the existing rough opening, check the jamb and header for plumb, and then install a new slab or pre-hung unit that closes flush, latches clean, and doesn’t bind when the house settles. A typical interior slab replacement in San Bruno runs $450 to $1,100 depending on the door type and whether the existing jamb needs rework. Pre-hung interior doors with new casing and hardware land between $900 and $2,200, and that includes hauling off the old door and frame.
Slab Swaps for Tight Framing
Many San Bruno homes built before 1960 have rough openings that are not square and not standard. We trim and fit the slab to the actual opening rather than forcing it and hoping. On a recent job near Belle Air, the old door had been sanded three times by a previous owner and still rubbed the jamb. The opening was fine; the slab was never fitted to begin with.
Pre-Hung Interior Doors
When a San Bruno homeowner wants a bathroom door that actually latches, or a bedroom door that blocks sound, a pre-hung unit with new casing is the better path. We pull the old frame, shim the new one level and plumb, and close up any gaps. The job usually takes half a day, and we leave the room clean enough to walk through barefoot.
Door Installers in San Bruno
Door installers in San Bruno have to handle the city’s real mix: flat-grid bungalows with shallow headers, mid-century tract homes with standard 80-inch rough openings, and hillside houses where the ground shifts just enough to make an old door jam. Our crew has been through all three. We don’t send a sub-contractor who shows up with a cordless drill and a six-pack of shims; every Juniper window-and-door technician is background-checked and in uniform, and the person who measures your door is the person who hangs it.
Exterior Door Replacement from Header to Threshold
The big risk in San Bruno exterior work is quoting a stock unit before measuring the rough opening. On many flat-grid homes, the header is shallower than a modern pre-hung door expects, so the replacement doesn’t fit without reframing. We catch that at the quote stage, which is why our written price includes the framing adjustments it actually takes, not just the door itself.
Fog-Belt Weatherproofing
The underside of a San Bruno door faces wet Pacific air for much of the year. We always check the sill pan, the threshold height, and the jamb-to-sheathing seal. Reusing old caulk on a fog-belt hillside door is how you get water inside the wall cavity within two winters. We replace it, every time, and we prime and seal before the trim goes back on.
Trusted Brands We Service in San Bruno
We stock and install across eight product lines, and for San Bruno doors specifically we lean on Therma-Tru for exterior entry systems, ViewLux for modern fiberglass and aluminum units where sightlines matter, and PGT for impact-rated options when a homeowner wants the extra wind-debris performance. If you’re matching a door to existing windows on a 1960s tract home near Sneath Lane, we can align the low-E glass specs with what your current units already have rather than telling you to accept a mismatch. Local parts availability means we’re not waiting on a shipped shim kit when the opening turns out a half-inch shallow.
Common Door Replacement Problems We See in San Bruno Homes
- Shallow headers on pre-war bungalows. A stock 96-inch rough opening assumption leaves the replacement door hitting the header. We measure height, not just width, before we quote.
- Fog-belt moisture rotting the jamb base. The west side of San Bruno, especially up toward Pacifica, gets enough marine air that an old jamb bottom will often be soft by the time the door needs replacing. We check for rot before the new unit goes in.
- Skipped permits on exterior envelope changes. San Bruno requires a permit when a door replacement changes the rough opening or the exterior envelope. Unpermitted work shows up at resale, and a neighbor’s inspector can cause problems retroactively. We handle the permit as part of the written scope.
- The previous owner’s big-box slab experiment. We see this on Crestmoor and Belle Air regularly: someone swapped a door without a header check, and now it sticks or drafts. Usually the fix is a proper jamb reset and a correctly sized slab, not a full reframe.
Pricing for Door Replacement in San Bruno, CA
A typical interior slab replacement in San Bruno runs $450 to $1,100. A pre-hung interior door with new casing is $900 to $2,200.

FAQs About Door Replacement in San Bruno
Yes, if the replacement changes the rough opening or the exterior envelope, San Bruno requires a building permit. A same-size slab swap in an existing frame may not trigger one, but widening a doorway, moving a header, or changing the exterior surface does. We confirm the permit scope during the quote and pull it as part of the written job; we don’t ask the homeowner to “just handle it” and we don’t skip it to keep the bid low. Call (682) 281-2168 to find out whether your specific door triggers a permit.
Most San Bruno exterior door replacements run two to five days from final measure to completed install, depending on the door type and whether the rough opening needs reframing. In-stock steel and fiberglass units can sometimes go in the same week you order. Custom sizes or impact-rated glass typically add one to two weeks. The install itself is almost always one day; it’s the ordering and any permit timing that stretch the calendar. We give you a written schedule with the quote, not a “we’ll call when it comes in.”
Yes. If your San Bruno home already has low-E double-pane windows, we can specify the replacement door with comparable low-E glass and a matching frame color from Therma-Tru, ViewLux, or the other lines we carry. Matching under frame color and glass tint on an older tract home matters for resale and for how the entry reads from the street. We’ll bring finish samples to the estimate.
The honest list: rotted jamb base or sill, a header that turns out to be shallower than the door needs, an out-of-plumb rough opening that requires shimming beyond standard, and permit-required reframing that wasn’t scoped when the first quote was written. All of those are items we catch during our initial measure, which is why our written price includes them before work starts. If something genuinely hidden shows up after the wall is open, we stop, document it with photos, and put the revised cost in writing before touching another screw. Call (682) 281-2168 to get a quote that reflects your actual opening, so there’s nothing to change later.
It does. On the San Bruno hills, Pacific air pushes moisture against the lower door edge and into the jamb, and an old or poorly sealed door doesn’t just leak air, it gives the condensation a place to sit. A properly installed exterior door with a new sill pan, sealed threshold, and low-E insulated glass keeps the warm side warm and the wet side out, which is exactly what our Crestmoor Drive patio door project showed: once the draft pattern was gone, the room held its temperature and the glass stopped sweating. We quote weatherproofing as part of every exterior door, not as an add-on.
