AfterFast, Reliable Door Replacement Across South San Francisco
Door replacement in South San Francisco usually runs $900 – $4,200 depending on whether you’re swapping an interior slab or a full exterior pre-hung unit with weather-rated glass. Most exterior jobs in this city take one to two days once the door arrives, and the biggest cost drivers tend to be the door’s material, whether the rough opening needs re-framing, and whether the existing sill pan has failed. If you’re looking at a door that sticks, leaks at the bottom during winter storms, or has rotted along the jamb, call us at (682) 281-2168 and we’ll scope it in person with a written price before anything gets ordered. We’re Juniper Windows & Doors, and we’ve been doing Door Replacement work long enough to know that South San Francisco’s wind-driven rain punishes shortcuts.
Why Juniper Windows & Doors Is South San Francisco’s Preferred Door Replacement Company
Sean Mackey leads our crews, and the standard he set from day one is that no door gets ordered until you’ve seen a line-item price in writing. South San Francisco homeowners tell us that’s the difference between us and the last contractor they called. You’ll know the exact cost of the slab, the frame, the flashing, the hardware, and the labor before we touch a screw. That price holds. If the work isn’t right, our 365-Day Done Right Promise covers parts and labor for a full year after installation. No fine print, no callback queue.
Our technicians come background-checked and uniformed. You’ll get a live arrival time you can track, before-and-after photos of the job, and a digital invoice you can pay from your phone. When you call (682) 281-2168, a real person picks up, 24/7. That matters when a storm rolls through the San Bruno Gap and your exterior door starts taking on water.
We stock parts for the brands that handle this climate best, including CGI, CWS, and Therma-Tru. A door that performs well in Daly City’s fog won’t necessarily survive South San Francisco’s different exposure, and we spec accordingly. No generic swaps, no guesswork.
Interior Door Installation in South San Francisco
Interior Door Installation in South San Francisco typically runs $400 – $900 per pre-hung door, including the slab, frame, casing, hardware, and labor, and it’s a one-day job in most ranch-style homes. The older housing stock here, especially 1950s and 1960s builds along El Camino Real and the Westborough area, often has door openings that have settled out of square. We true the rough opening before we set the new frame, or the door will bind at the jamb within months.
Pre-Hung Door Rebuilds
In a 1950s rancher near Alta Loma Park, the original interior doors are often hollow-core with loose hinges and cracked jambs. Replacing those with solid-core pre-hung units changes how the house feels and sounds. We shim to level, case both sides, and leave the opening clean. Expect about three to four hours per door in a standard 2×4 wall.
Slab Swaps on Existing Frames
If the jamb is square and solid, we can replace just the slab and keep your existing frame. In South San Francisco that’s usually $250 – $450 per door, and it’s the fastest route when you want modern hardware but don’t want to disturb the trim. Not every opening qualifies, and we’ll tell you honestly if you’re better off with a full pre-hung replacement.
Door Installers in South San Francisco
Our Door Installers in South San Francisco handle everything from a single exterior entry door to a full multi-unit replacement in the hillside neighborhoods off Hillside Boulevard and along Chestnut Avenue. We don’t sub the work out to day labor. The same crew that scopes your job is the crew that installs it, and they’re trained on the specific water-management details this city demands. An exterior door replacement here is not just a panel swap. It’s a flashing, sealing, and drainage job wrapped around a panel.
Exterior Entry Door Replacement
A full exterior entry replacement in South San Francisco typically runs $1,800 – $4,200 with a fiberglass or steel door, new weather seals, sill pan, and hardware. That includes removing the old frame, addressing any rot at the subfloor or jamb, and setting the new unit level and weather-tight. Most jobs complete in one day, though severe rot at the threshold can push it to two.
Sliding and French Door Replacement
Sliding patio doors in South San Francisco generally run $2,500 – $5,500 installed, and the bigger cost variable is usually the rough opening condition, not just the door itself. French doors land in the $3,000 – $6,000 range. On hillside homes with west-facing rear exposures, we recommend impact-rated glass and a reinforced frame. The wind coming off the San Bruno Gap doesn’t let up, and a cheap track system will rattle and leak within two seasons.
Trusted Brands We Service in South San Francisco
We work with eight product lines, and we stock local parts for South San Francisco customers in CGI, CWS, and Therma-Tru. For this city specifically, we steer exterior door customers toward fiberglass over steel when the home sits in the fogbelt, because salt-tinged moisture and wind-driven rain attack steel door edges at the bottom rail faster than anything else. For patio and sliding units, CGI and CWS impact-rated glass can handle the wind exposure along the bay side of the city. We’ll spec the right product for your specific street, not just your zip code.
Common Door Replacement Problems We See in South San Francisco Homes
- Water tracking under the threshold during storms. South San Francisco sits in a wind-driven rain zone, and an exterior door with a failed sill pan will let water pool at the jamb base. The door slab looks fine. The subfloor underneath is rotting. We see this on pre-1960s ranches all over Sunshine Gardens.
- Out-of-square rough openings in older ranch homes. The 1950s housing stock here has settled. A pre-hung door that drops into an out-of-square opening will bind at the top or latch side. We true the opening before setting the new frame, or the door fights you every time you close it.
- Interior-grade doors installed as exterior doors. A door without a weather-rated bottom rail and proper exterior finish will swell and delaminate from fogbelt moisture. The bottom rail is usually the first thing to go. We replace these with doors designed for this climate, not whatever was cheapest at the lumberyard.
- Patio sliders that rattle and leak on exposed hillsides. Homes on the western slope above El Camino Real catch the full force of the San Bruno Gap wind. A basic sliding door with a cheap track system will leak air, water, and sound. We replace them with properly flashed impact-rated units.

FAQs About Door Replacement in South San Francisco
Yes, if you’re replacing the door in an exterior wall and altering the opening size or structure, South San Francisco requires a building permit and a final inspection. A straight same-size replacement often qualifies as a repair and may not need a permit, but we check with the city on every job. We pull permits for you when they’re required, and we schedule the inspection so you don’t have to manage the city yourself. Call (682) 281-2168 and we’ll tell you exactly what your project needs.
Because South San Francisco sits in the San Bruno Gap wind-driven rain zone, water gets pushed horizontally against your door. If the sill pan under the threshold lacks end dams or the door-bottom weather seal is worn, water tracks under the door into the subfloor. The fix is usually a stainless sill pan with end dams and a full-perimeter gasket, not just a new sweep. Call us for an inspection, and we’ll show you photos of what’s actually failing.
Sometimes, if the jamb is square, solid, and not rotted, we can swap the slab and keep the existing frame. Based on what we see across South San Francisco’s older ranches, about half of jamb retrofits need more work once we open the casing. We’ll scope it in person, tell you honestly, and price either path in writing before we start. Call (682) 281-2168 for a free estimate.
Most interior doors go from order to installed in five to ten business days. Exterior doors with custom sizing or impact-rated glass typically take two to four weeks from deposit to install, depending on the manufacturer’s lead time. The on-site work itself is usually one to two days. We’ll give you a calendar with dates at the time of contract, and the install date on that calendar is the date we show up.
Only conditions we couldn’t see before demolition: rotted subfloor under the threshold, a rough opening that needs re-framing to be square, or hidden termite damage at the jamb. In Sunshine Gardens and the older homes off Hillside Boulevard, sill pan rot is common, and we’ll show you photos before we do any added work. The price we hand you before work starts covers the scope we agreed on. If we find something behind the wall, you approve the change in writing first. That’s the standard.
Call (682) 281-2168 to schedule your free estimate. We’ll send a background-checked, uniformed technician to your door in South San Francisco, scope the work, and hand you a written price before you commit to anything.
