Door Replacement in San Dimas - Free In-Home Measure, Written Price

Fast, Reliable Door Replacement Across San Dimas

Door replacement in San Dimas typically runs $1,200 to $4,800 for a standard exterior entry, with front doors using impact-rated glass or WUI-compliant units landing closer to $3,500 to $6,500. Most jobs take one to two days once the door is in hand. If your existing frame is twisted, rotted, or out of plumb, expect to add reframing, which pushes the total toward the upper end of that range. Sean Mackey and the team at Juniper Windows & Doors handle the whole scope, from first measurement to final inspection, and every project gets a written price before work starts. We also offer our Window Installation in San Dimas for homeowners looking to upgrade both doors and windows together. Call (682) 281-2168 and we’ll walk the space with you.

Why Juniper Windows & Doors Is San Dimas’s Preferred Door Replacement Company

San Dimas homes sit tight against the San Gabriel foothills, and that changes how a door should be specified. Foothill-facing exterior doors get hammered by afternoon sun and dry Santa Ana wind, so a door that works fine in La Verne or Glendora may fail early here. We scope door replacement against the city’s actual conditions, not a catalog photo. Our techs know which San Dimas neighborhoods trigger WUI requirements and which don’t, and we price the job with that in mind from the first visit.

We’re part of Relay Home Co., founded in 2001, and every job is covered by the 365-Day Done Right Promise: if the install isn’t right, we make it right, parts and labor, for a full year. San Dimas customers also get the Relay Visibility Guarantee: a live arrival time, before-and-after photos, and a digital invoice. You’ll know exactly who’s coming, when, and what it costs before any work begins. No four-hour windows. No estimate that morphs into a surprise invoice.

Door Contractors in San Dimas

Door Contractors in San Dimas do a lot more than pull an old slab and screw in a new one. Most of our work here starts with a door that no longer latches, binds at the jamb, or lets afternoon heat pour through the glass. Our Door Replacement team measures the rough opening, checks the existing frame for plumb and twist, and confirms whether the door needs to meet San Dimas WUI exterior requirements before we order anything. A straightforward slab-and-hardware swap on a mid-century ranch typically falls between $1,200 and $2,400, while full tear-outs with reframing and impact-rated glass run $3,200 to $6,500.

For homes off Via Verde or up against the foothill edge, the scope often includes a low-E insulated glass unit or impact-rated sidelite. We order the door to fit the framing, not the other way around. That’s the difference between a door that closes clean for a decade and one that starts sticking by the next dry season.

Full Entry System Replacement

We remove the old door, frame, and hardware, then set a new pre-hung unit with fresh weatherstripping and a properly shimmed jamb. This is the right scope when the existing frame is twisted from decades of thermal movement or when you need to bring the assembly up to current WUI standards.

Slab and Hardware Swap

If the frame is square and the jamb is in good condition, we can replace the slab only and reuse the existing frame. We replace hinges, threshold gaskets, and strike hardware as part of the job. The slab itself gets sized to the actual rough opening, which matters a lot in older San Dimas homes where nothing is perfectly square.

Door Frame Repair in San Dimas

Door Frame Repair in San Dimas is the fix for doors that sag, bind, or won’t latch, and it’s one of the most common calls we get from homeowners in the older ranch neighborhoods. Most San Dimas frames were set decades ago, and years of soil movement and dry-season shrinkage leave them out of plumb. Rather than forcing a new door into a twisted frame, we correct the jamb itself with new shims, fresh fasteners, and full adjustment. A simple frame straighten with hardware reset runs $350 to $850, while full jamb replacement, including trim and weatherseal, runs $900 to $1,800 depending on whether WUI-rated components are needed.

One recent job near Via Verde started as a warped Therma-Tru entry door that had swollen after a dry summer and wouldn’t latch. Our tech confirmed a twisted jamb, pulled the old slab and frame, reframed with a new jamb, and set an impact-rated Therma-Tru unit with a low-E insulated glass sidelite. The entry met the fire-adjacent exterior requirement and cut the afternoon heat gain through the glass in one shot.

Jamb Straightening and Hardware Reset

When the door binds at the top or latch side, we remove the casing, release the old shims, and reset the jamb dead plumb. Then we rehang the door and adjust strike plates so the latch seats cleanly. Most jobs take half a day.

Rotted or Split Jamb Replacement

San Dimas gets enough winter moisture against the foothills that bottom jamb sections can rot where water pools at the threshold. We cut out the damaged section or replace the full leg, then flash and seal the new wood so water can’t sit against it again.

Trusted Brands We Service in San Dimas

We work heavily with Therma-Tru, PGT, and ViewLux on San Dimas replacements, and we keep local stock of the components those units need. Whether it’s an impact-rated PGT slab for the Via Verde foothill edge, a Therma-Tru fiberglass entry with low-E sidelite, or a ViewLux aluminum door for a modern build up toward the hills, the door gets specified for how it’ll actually live in this climate. We also service CWS and CGI units. Parts that would take a general contractor days to source, we typically have moving within a week for San Dimas customers. That keeps the calendar honest.

Common Door Replacement Problems We See in San Dimas Homes

• Out-of-plumb mid-century jambs. Homes built in the 1950s and 60s across San Dimas have frames that drifted over decades. A new door dropped into an old twisted jamb will bind within months. We check plumb on every job and correct it before the new unit goes in.
• WUI and fire-severity confusion. San Dimas sits in a high-fire-severity area along the San Gabriel foothills. Exterior doors in the WUI overlay need fire-rated or ignition-resistant components, and a contractor who scopes the job without checking the parcel can force a reorder after the permit is pulled.
• Afternoon heat gain through west-facing glass. Doors facing the foothill edge catch direct afternoon sun for hours. Standard glass seeps heat into the entry and can fail early at the seal. Low-E insulated glass or impact-rated glass makes a real difference on these exposures.
• Stock slab assumption. We regularly see homeowners buy a “standard” 36-inch slab from a big-box store and then discover their San Dimas jamb is 35 7/8 or out of square left-to-right. A custom-ordered slab sized to the actual opening avoids the frustration.
