Fast, Reliable Door Replacement Across Claremont
If your door sticks, sags, or lets daylight through the edges, the replacement process in Claremont typically runs $900 – $2,400 for a standard exterior door and $350 – $800 per interior door, installed. Those numbers cover the door itself, the jamb work, hardware, and haul-away of the old unit. The real question in Claremont is which kind of opening you have: a pre-war bungalow jamb or a standard tract-home frame. That’s what changes the scope, the permit path, and the final number. Juniper Windows & Doors handles both, and we’ll give you a written price before anything gets ordered. Call (682) 281-2168 to schedule a free estimate.
Why Juniper Windows & Doors Is Claremont’s Preferred Door Replacement Company
We’ve worked on enough Claremont homes to know the difference between a 1920s Village-adjacent Craftsman and a 1990s planned tract in the north end. That’s not trivia. It changes which jamb depth the crew brings, whether City of Claremont historic-context review applies, and whether an out-of-square rough opening needs a jamb rebuild before the new slab goes in. Sean Mackey runs our Claremont work with the same standard we apply everywhere: background-checked, uniformed technicians, a written price before work starts, and the 365-Day Done Right Promise covering every completed installation for a full year, parts and labor, in writing.
The Relay Visibility Guarantee is the other difference. When you book with Juniper, you get a live arrival time you can track on your phone, before-and-after photos of the job, and a digital invoice you can pay from a link. No four-hour windows, no wondering who’s showing up. You’ll know exactly who’s walking through your door because every tech is background-checked and in uniform. That matters when a crew is inside your home for a full day reframing a jamb.
We’re part of the Relay Home Co. family, founded in 2001, and we specialize in doors and windows. That’s the entire job. Not roofing, not plumbing, not a general remodel. Doors. Windows. Done right, priced in writing, backed for a year.
Door Frame Repair in Claremont
Door Frame Repair in Claremont is often the actual fix when the slab itself is still solid but the jamb has rotted, settled, or been planed so many times the strike plate no longer catches. On older Claremont homes, this is common. Original jambs on 1920s bungalows are usually 1¾-inch-thick wood, and once Claremont’s shrink-swell clay soil shifts the foundation even a quarter inch, the door binds top hinge or bottom latch and the old jamb gets chewed up. A straightforward frame repair in Claremont runs $250 – $600. A full jamb replacement, where we remove the old frame, rebuild it square, and re-hang the door, runs $600 – $1,200 including trim and painting the exposed edge.
When Repairs Beat Replacement
Not every door problem in Claremont means buying a new door. If the wood around the hinges is solid, we’ll cut out the rotted section, splice in new wood, and reset the jamb square. That’s a half-day fix versus a full-day replacement. It saves the original look, which matters on older Claremont homes where the jamb profile and trim are no longer made.
Full Jamb Rebuilds on Older Homes
Some Claremont frames aren’t salvageable. We swapped a rotted back-door assembly at a 1920s bungalow near the Claremont Colleges where the original jamb had swelled past the strike plate and the door had been planed twice already. Our tech reframed the opening, set a Therma-Tru fiberglass slab with a low-E insulated glass unit in the lite, and tied the new threshold into the existing stucco instead of face-nailing a trim board over it. The homeowner finally had a door that latched on the first push and a west-facing lite that stopped cooking the hallway. In Claremont, that kind of work runs $1,200 – $2,000 depending on the stucco tie-in and whether we’re swapping in a pre-hung unit or reusing the original casing.
Interior Door Replacement in Claremont
Interior Door Replacement in Claremont runs $350 – $800 per door when you’re swapping slabs in standard 1980s – 2000s tract frames. Those are typically 4-9/16-inch builder jambs, hollow-core doors, and they go in fast. The cost shifts on pre-war Claremont homes where the original openings were built for solid-wood doors: the jamb depth is different, the hinges are spaced for heavier slabs, and the trim profiles from the 1930s are not something you’ll find at a Claremont big-box store. We’ll match the weight, the sound, and the profile. That’s the part of the job that separates a proper replacement from a cheap slab swap.
Hollow-Core vs. Solid-Core in Claremont
The fast answer: if you live in a Villa or other planned tract built after about 1980, your interior doors are likely hollow-core. Replacing them like-for-like is straightforward and keeps the cost low. If your home is in the Village or along Indian Hill Boulevard with original 1930s trim, the original doors were solid wood. A cheap hollow-core replacement will sound different, feel light, and look wrong next to original millwork. We always ask which neighborhood you’re in before recommending a door.
Why the Frame Comes First
We never order an interior door in Claremont without measuring the rough opening first. Decades of clay-soil movement leaves openings out of square by a half-inch or more. If the frame is out of square, the new door will bind regardless of how much it cost. We square the jamb first, then hang the door. That’s why our written quotes include frame work when it’s needed, not as a surprise add-on later.
Trusted Brands We Service in Claremont
Juniper carries eight product lines, and for Claremont we lean on PGT and CGI for exterior doors that have to handle the inland summer heat and occasional heavy wind, plus Therma-Tru for fiberglass slabs that hold up to the sun without warping like wood. We also stock CWS hardware and lites for local customers who want impact-rated glass, which is built to resist wind-borne debris without shattering. Because we install these brands every week, we can often pull Claremont-specific parts from local inventory instead of waiting for a regional order. That keeps your install window short.
Common Door Replacement Problems We See in Claremont Homes
- Doors that bind in summer. Claremont’s clay soil swells in the rainy months and shrinks in the dry heat, and this movement is most visible as a door that latches fine in January and won’t close by August. Fixing it properly means squaring the jamb, not planing the door thinner each year.
- Out-of-square rough openings. On Claremont tract homes from the 1980s onward, builders often set door frames quickly. Decades of minor movement later, a stock 80-inch slab won’t fit without jamb work. This is the single most common reason an easy door replacement becomes a half-day longer.
- Cracked or warped hollow-core interior doors. The dry inland air across Claremont pulls moisture from cheap door skins, and hollow-core doors warp on the edges. They develop a bow you can see from the hallway rather than a clean face.
- Original doors that don’t meet modern expectations. Pre-war Claremont bungalows have solid doors with real character, but the old hardware is tired, the door no longer seals, and the original lite glass is single-pane. Replacing the door while preserving the opening is what we do most on Village-adjacent work.

A standard exterior door replacement in Claremont runs $1,200 – $2,400 installed, including the slab, pre-hung jamb, hardware, threshold, and haul-away.

FAQs About Door Replacement in Claremont
Yes, exterior door replacements in Claremont typically require a building permit through the Community Development Department, and the answer is usually yes for any exterior opening where the door is being replaced with a different size, material, or swing. On older Village-adjacent homes, the city may also route the permit through a historic-context review before approval. We handle the permit paperwork on the jobs where it’s required, and we’ll tell you during the estimate whether your specific door falls into that category. Call (682) 281-2168 to ask about your particular home.
Claremont’s shrink-swell clay soil is the usual culprit. It holds water through the winter, expands, and pushes the foundation slightly in sections, which throws the door frame out of square by summer when the soil dries and contracts. The fix is a jamb adjustment or rebuild, not another pass with a planer. We’ll square the frame, reset the hinges, and the door will latch cleanly year-round. A jamb correction in Claremont runs $250 – $600 depending on how far out of square the opening has moved.
Three things: the jamb depth, the condition of the rough opening, and the hardware spec. Claremont pre-war homes usually have thicker 1¾-inch wood jambs, which cost more to match. Clay-soil movement often leaves the opening out of square, which means a jamb rebuild gets added to the work. And the door’s build, whether it’s a standard hollow-core interior slab or a fiberglass exterior unit with a low-E lite, changes the material cost. All three are priced in writing before we start, so nothing you find once the door comes off changes the number. Call (682) 281-2168 and we’ll walk your specific door through that list.
A standard exterior door on a tract home in Claremont is a one-day install, assuming the permit is already in hand. Permit processing through the city adds a few days to a week depending on the week. Interior door swaps run a half-day for one or two doors. Older Claremont homes where we’re rebuilding a jamb and matching trim should plan for a day and a half. Permits, historic-context review on Village-adjacent work, and custom-door lead times are what stretch the calendar on Claremont jobs, and we’ll give you a dated schedule as part of your written quote.
Yes, and that’s the work our Claremont clients care about most. If your Village-adjacent bungalow or Spanish Colonial Revival home still has the original 1930s solid-wood door, we’ll match the weight, the jamb depth, the hinge spacing, and the trim profile rather than dropping in a stock 80-inch slab. In some cases the original door can be repaired instead of replaced. When replacement is the right call, we source solid wood and period hardware that looks like it was always there. Call (682) 281-2168 and we’ll take a look at the door, the trim, and what can be saved.
If your door is warped, rotted, or simply tired, start with a free estimate. We’ll measure, scope the jamb, tell you what the Claremont permit path looks like, and hand you a written price that won’t change. Call (682) 281-2168 to schedule your estimate with Juniper Windows & Doors.
