AfterFast, Reliable Door Replacement Across Redwood City
If you’re searching for door replacement in Redwood City, here’s the straight answer: a standard exterior door swap on an existing frame runs $900 – $1,800, a full tear-out with new frame, seismic re-anchoring, and permit runs $2,400 – $4,500, and a basic interior door replacement with hardware sits around $400 – $800 per opening. Most jobs in Redwood City take two to three weeks from signed contract to final inspection, not because the labor is slow but because the City’s Residential Permit review and the required inspection sequence need their own days on the calendar. We schedule Redwood City jobs Monday through Saturday, and our crews arrive with a live arrival time you can track, not a four-hour window. Call (682) 281-2168 for a written quote before anything starts.
Why Juniper Windows & Doors Is Redwood City’s Preferred Door Replacement Company
Our Door Replacement crews work Redwood City neighborhoods every week, from the bungalow blocks around Roosevelt to the mid-century ranches off Woodside Road and the newer townhomes near Redwood Shores. That regular presence means we already know the permit desk at City Hall, the inspectors who sign off on exterior door rough-ins, and the difference between a 1920s cripple-wall detail and a 1990s tract home rough opening. Sean Mackey leads the Redwood City door work, and he has built the team around one habit: write the full price down before the first screw comes out.
Homeowners in Atherton and Menlo Park sometimes assume Redwood City door replacement needs coastal hardware, but the truth is simpler than our Window Installation in Redwood City customers often expect. Redwood City’s climate is mild and dry enough that impact-rated glazing is rarely required here. The real local drivers are seismic re-anchoring under CBC Chapter 16 and the City’s Residential Permit trigger for exterior door swaps. That’s why our Redwood City quotes include the permit line item, the structural screw pattern, and the inspection calendar, not vague “weather-rated hardware” language that belongs two towns west. Every Redwood City project carries the 365-Day Done Right Promise: 365 days, parts and labor, in writing.
Door Frame Repair in Redwood City
Door Frame Repair in Redwood City most often comes down to one issue we see across the city’s older housing stock: a frame that has racked out of square because the rough opening was never properly anchored to the king studs. Redwood City sits on expansive clay soils, and older slab-on-grade homes move seasonally. A door that binds at the top in August and swings loose in January is a frame problem, not a hinge problem. We reframe jambs with pressure-treated lumber, re-anchor with structural screws into the king studs, and shim and foam the perimeter so the slab can shift without throwing the latch out of alignment. Typical Redwood City door frame repair runs $450 – $1,100 depending on how much of the rough opening has to be rebuilt.
When the Threshold and Jamb Base Have Rotted
Winter rains in Redwood City pool against entry doors that were never detailed with a sill pan and back-dammed flashing. We open the jamb base and routinely find rotted subfloor that goes six inches past the visible damage. The repair means cutting out the rot, treating the framing, installing a proper sill pan, and setting the door back at the correct elevation. Expect $600 – $1,400 for a threshold and jamb-base rebuild in Redwood City, including the flashing work that actually stops the next rainy season call-back.
Seasonal Binding Without Visible Rot
If the door has no rot but sticks every summer, the frame has racked and the fix is re-anchoring rather than replacing the door slab itself. We pull the casing, expose the rough opening, and secure the frame to the studs with structural screws on a pattern an inspector will approve. This runs $350 – $800 in Redwood City and usually resolves the seasonal bind for good.
Interior Door Replacement in Redwood City
Interior Door Replacement in Redwood City is usually about one of three things: a hollow-core door from the 1970s that has been kicked in, a swinging door that eats floor space in a small Redwood City bedroom, or a style upgrade to match the mid-century casing profiles common in homes off Alameda de las Pulgas. We replace interior doors in Redwood City with solid-core or hollow-core slabs, pre-hung units where the frame has moved, and hardware that matches existing finishes or gets swapped to matte black or brushed nickel. A standard interior door replacement with new hinges and hardware runs $400 – $800 per opening in Redwood City. Pre-hung replacements with frame work, trim, and paint touch-up run $650 – $1,100.
Pre-Hung vs. Slab Replacement
A slab replacement means we hang a new door on the existing frame, which works when the frame is square and the jamb is sound. A pre-hung replacement includes the frame, and that’s the right call in Redwood City bedrooms where the original 1950s jambs have drifted out of square from decades of slab movement. Pre-hung costs more because it includes trimming out the opening and re-casing the interior side.
Hardware and Latch Upgrades
Many Redwood City homeowners take the opportunity to replace passage hardware with quiet-close hinges and privacy sets while the door is off. We stock common hardware finishes and can match most existing handlesets same week. The hardware line item is typically $40 – $160 per door, depending on finish and lock grade.
Trusted Brands We Service in Redwood City
Juniper Windows & Doors carries PGT, Therma-Tru, and ViewLux product lines, and for Redwood City customers the Therma-Tru Smooth-Star and Pulse lines are the most common choices for exterior doors because they handle daily sun exposure without warping. For sidelites and glass-in-door panels we spec low-E insulated units that bring daylight without adding heat load to a Redwood City front room. We keep common Therma-Tru and ViewLux parts stocked locally so a follow-up adjustment or hardware swap does not mean waiting on a freight shipment. Sean Mackey can walk you through the product lines by phone and give you a written price on any of them.
Common Door Replacement Problems We See in Redwood City Homes
- Permit-skipping on exterior door swaps. Homeowners assume a like-for-like front door replacement does not need a permit, but Redwood City triggers a Residential Permit for any exterior door swap that alters the opening or header. Skipping it means correction later, re-inspection fees, and potential re-work on a header the inspector never saw.
- Plumb-and-level failures from clay soil movement. Expansive clay under Redwood City’s older slab-on-grade foundations moves with the seasons, and a door frame anchored only through the casing into drywall will rack out of square. We see this every week in homes built before 1980.
- Moisture ingress at the threshold and jamb base. Redwood City’s winter rains pool against doors that were not detailed with a sill pan and back-dammed flashing, and the result is rotted subfloor that shows up a full season after the original install.
- Original 1990s fiberglass doors on failing frames. The door slab is often fine; the frame around it is gone. We replace the frame, re-anchor it properly, and keep the slab when it is still serviceable, which saves Redwood City homeowners roughly $900 off a full tear-out.
Pricing for Door Replacement in Redwood City, CA
Door replacement pricing in Redwood City breaks down like this: a slab-only interior door is $400 – $800, a pre-hung interior door with trim runs $650 – $1,100, an exterior door swap on a square frame runs $900 – $1,800, and a full exterior tear-out with new frame, structural re-anchoring, sill pan, and permit runs $2,400 – $4,500. The biggest cost driver is what we find when the casing comes off: rotted subfloor, a racked rough opening, or a header that was never sized right. Those conditions add $300 – $900 to the job, and we will show you exactly that line item in writing before we touch it. Every Redwood City quote includes the permit fee, the inspection scheduling, and the 365-Day Done Right Promise. Call (682) 281-2168 for a free estimate with a written, line-item price.

FAQs About Door Replacement in Redwood City
Yes. Redwood City triggers a Residential Permit for any exterior door replacement that alters the opening or the header, which includes most front door and back door swaps. The permit includes a rough-in inspection and a final inspection, and we pull it for you as part of the job. Call (682) 281-2168 and we will tell you whether your specific door triggers the requirement before you commit to anything.
Your door frame has likely racked out of square because the rough opening was never properly anchored to the king studs, and Redwood City’s expansive clay soils cause the slab to move seasonally. The fix is re-anchoring the frame with structural screws into the studs, not planing the door. Planing the door will make it swing freely in summer and rattle in winter. Call (682) 281-2168 for an assessment and a written quote.
Rarely. Redwood City’s building climate is mild and dry enough that impact-rated glazing, which is built to resist wind-borne debris without shattering, is usually over-spec here. What Redwood City does require is seismic re-anchoring under CBC Chapter 16 and a permit for exterior door swaps. We will not sell you impact-rated glass unless your specific exposure or the city asks for it. Call (682) 281-2168 for a straight answer on your door.
Plan on two to three weeks. The labor on a standard exterior door is one to two days, but Redwood City’s permit review and the required inspection sequence add their own calendar days. We schedule the rough-in inspection, the final inspection, and the work dates at contract signing so you see the full calendar up front. Call (682) 281-2168 for a schedule specific to your project.
The price changes when the wall is open and we find conditions we could not see from the outside: rotted subfloor at the threshold, a rough opening that was never anchored to the studs, or a header that has to be re-sized. Each of those is a specific line item we show you in writing before we do the work, not a surprise invoice at the end. You approve the change before we touch it. Call (682) 281-2168 to talk through what we might find in a Redwood City home of your vintage.
