AfterFast, Reliable Door Replacement Across Pomona
Door replacement in Pomona typically runs $900 to $4,200 depending on whether you’re swapping an interior slab or installing a new exterior entry system with low-E glass and proper weather sealing. Most Pomona jobs take one day for a standard pre-hung exterior unit, unless we’re re-framing a rough opening or correcting flashing damage from past installs. We know the San Gabriel Valley heat, the older mid-century stock around Lincoln Park and Westmont, and the way a single-pane door can leak conditioned air straight out of your living room. If you’re looking at a door that sticks, drafts, or just looks tired, call (682) 281-2168 and we’ll walk you through the scope and the written price before anything gets ordered.

Interior Door Installation in Pomona
Interior Door Installation in Pomona means swapping a hollow-core slab for something that closes quietly, aligns squarely, and doesn’t catch the frame every time the humidity shifts. We handle pre-hung units, slab replacements on existing jambs, and pocket door retrofits. Most Pomona interior doors run $250 to $700 per opening installed, depending on whether it’s a flat-panel slab or a solid-core door with new casing and hardware prep.
Pre-Hung Interior Doors
We pull the old jamb, shim the new one level, and trim it out. Pre-hung units in Pomona homes typically run $400 to $900 per opening including the door, jamb, casing, and basic hardware. Solid-core doors cost more but cut hallway noise noticeably, which matters in older Pomona bungalows where bedrooms sit close together.
Interior Slab Replacement
If your existing jamb is square and the hinges are solid, we can route a new slab to match. That’s usually $200 to $400 per door for a standard hollow-core or $350 to $650 for solid-core. We match swing, backset, and bore locations so the new door drops into the old opening without tearing out trim.
Door Installers in Pomona
Door Installers in Pomona should arrive with a level, a tub of flashing sealant, and an understanding of how a west-facing entry bakes in the afternoon San Gabriel Valley sun. Our installers are background-checked, uniformed, and dispatched from the brand’s Los Angeles office to serve Pomona directly. A standard exterior door replacement runs $1,200 to $3,800 installed, including trim, hardware, weather stripping, and new flashing.
Exterior Pre-Hung Entry Systems
We install pre-hung entry doors with a full tear-out of the old frame. That means new jamb, new threshold, new exterior casing, and proper flashing shingled under the weather barrier so winter rains don’t find their way behind the siding. Expect $1,800 to $3,800 for a quality steel or fiberglass unit with insulated glass.
Patio and Garden Door Replacement
Sliding glass doors and French garden doors in Pomona run $1,500 to $4,200 depending on glass package and width. Low-E glass with a strong SHGC rating is the upgrade that pays back quickest in a Pomona summer. We adjust the jamb and rollers so the door tracks cleanly instead of dragging and wearing out the weather strip.
Trusted Brands We Service in Pomona
We install and service Therma-Tru exterior doors, PGT impact-rated glass packages, ViewLux vinyl and aluminum units, and CGI coastal-rated systems for Pomona homeowners who want maximum durability. We keep common hardware, sweeps, and thresholds in local stock for Pomona callbacks, so a sticking door or failed seal can often be corrected on the first visit without a second trip. If your existing door came from a fire-replacement program or a big-box retrofit, we can still service it and match the finish on your replacement panels. Sean Mackey’s crew will tell you honestly whether a repair or a full replacement makes more sense for your situation.
Common Door Replacement Problems We See in Pomona Homes
- Improper flashing around the door frame. Older Pomona homes often have the original door pan flashing done wrong or long since dried out. Water gets in during winter rains and rots the rough opening from the inside out, and by the time you see the stains, the jamb is already compromised.
- Interior-grade doors used on exterior openings. A hollow-core interior slab on a Pomona exterior opening means high air leakage and miserable summer cooling bills. We swap those for insulated fiberglass or steel units with proper weather stripping and a thermal break in the threshold.
- Door jamb misalignment from settling. Pomona’s clay-rich soils expand and contract with seasonal moisture, and older foundations shift. A door that sticks in winter may be the frame, not the slab, and correcting the jamb before it wears out the hinges saves you a full replacement down the line.
- Single-pane glass in west-facing doors. The afternoon heat off the San Gabriel Valley floor can push interior temperatures up ten degrees in a room with a single-pane door. Low-E insulated glass is the fix, and it pays for itself over two or three Pomona summers.
Pricing for Door Replacement in Pomona, CA
A standard interior slab replacement in Pomona runs $200 to $400 for hollow-core, or $350 to $650 for solid-core. Pre-hung interior units run $400 to $900. Exterior entry doors run $1,200 to $3,800 installed, and patio sliders or French units run $1,500 to $4,200 depending on glass package and opening width. The biggest cost drivers are the door material, whether we’re re-framing a rough opening, the glass package, and the amount of rotted framing we find once the old unit comes out. We give you a written line-item price before any work starts, and that price doesn’t change unless we find hidden rot that has to be corrected for the door to seal. Call (682) 281-2168 for a free estimate. You’ll get a number in writing, not a ballpark and a shrug.

FAQs About Door Replacement in Pomona
In most cases, replacing an exterior door in Pomona in the same rough opening does not require a permit, but if we’re changing the opening size or adding a new side-light, the city may require a simple permit and inspection. We handle the paperwork and coordinate the inspection so the job passes the first time. Call (682) 281-2168 and we’ll tell you exactly what your specific opening requires before we write the estimate.
Low-E insulated glass with a low SHGC rating is the best glass for Pomona doors because it blocks the worst of the San Gabriel Valley summer heat while still letting natural light through. Coastal impact ratings matter less here than thermal performance, so we spec glass for heat gain, not hurricane debris. A low-E door typically adds $200 to $500 to the door price and pays back fast on summer cooling bills.
A standard exterior door swap in Pomona takes one day from tear-out to trim. Interior slab replacements take two to four hours per door. If we find rotted framing or need to widen a rough opening, expect a second half-day. We’ll give you a written calendar with the estimate, and you’ll get a live arrival time so you’re not waiting around all day.
The honest answer: hidden rot in the rough opening. We plan the price around what we can see, but once the old door is out, Pomona homes sometimes reveal water-damaged framing from years of failed flashing. If that happens, we stop, show you photos, and give you a written change order with the exact additional cost before we touch anything else. You approve the number first, every time.
We install and service Therma-Tru fiberglass entry systems, PGT impact-rated units, ViewLux vinyl and aluminum doors, and CGI systems for homeowners who want the strongest frame on the block. We don’t push a brand just because it’s on the truck; we match the door to your opening, your energy goals, and your budget. Call (682) 281-2168 to talk through what makes sense for your Pomona home.
