Fast, Reliable Door Replacement Across Kirby
Door replacement in Kirby, TX typically runs $450 – $2,800 depending on whether we’re swapping an interior slab or reframing an exterior opening. Most Kirby jobs are completed in one day, with exterior pre-hung units sometimes taking two when stucco repair or threshold rebuilds come into play. We’re the Kirby door team that shows up with a live arrival time, a written price before work starts, and techs who know exactly what hides behind a 1960s ranch home’s original door casings. Call (903) 488-7019 to schedule your free estimate.
Kirby’s housing stock was largely framed between the 1950s and 1970s, which means the door openings we open up rarely match what a modern pre-hung unit expects. That’s not a problem if you know it’s coming. It’s a problem if the installer discovers it mid-job and suddenly the price moves. We inspect first, write allowances into the contract, and price any surprise in writing before we touch a hinge.
Our Door Replacement crews serve Kirby from the San Antonio office, dispatched with the parts and framing lumber most Kirby jobs actually need on the truck. We know Ackerman Road ranches, the brick-veneer homes off Binz-Engleman, and the older stock near FM 78. That local familiarity means fewer return trips and fewer “we’ll have to order that” conversations.
Why Juniper Windows San Antonio Is Kirby’s Preferred Door Replacement Company
Kirby homeowners keep calling us back for one simple reason: we write the price down before we start, and we stand behind the work for 365 days, parts and labor, in writing. That’s the 365-Day Done Right Promise. If the door isn’t right, we make it right. No charge, no argument.
Every Kirby job gets a background-checked, uniformed technician. You’ll know exactly who’s walking up the driveway, and you’ll have a live arrival time on your phone the same way you’d track a ride. Before-and-after photos are standard, not an upsell. We answer the phone with a live person 24/7 because nobody should have to leave a voicemail to ask why their front door won’t latch anymore.
Sean Mackey leads the team, and his standing rule for Kirby work is that no wall gets opened without a plan for what we might find. Rotted jambs, out-of-square rough openings, corroded thresholds – these are common on Kirby’s older ranch homes, and they’re all priced into the contract as allowances before the first hinge is pulled. If the surprise is small, we handle it. If it’s structural, you approve the number in writing first.
Interior Door Installation in Kirby
Interior door installation in Kirby usually means replacing hollow-core slabs with solid-core or molded-panel units in homes where the originals have warped, split, or simply never closed right. Most Kirby ranches from the 1950s through 1970s were trimmed with hollow-core doors that were light and cheap. After 50 years of South Texas humidity, they swell in summer and rattle in winter. Typical slab replacement runs $450 – $900 per door installed, while full pre-hung units with new jambs land in the $700 – $1,400 range when the rough opening needs correction.
Slab Swaps vs. Pre-Hung Units
If the existing jamb is square and solid, we can hang a new slab on the old frame and save you real money. If the jamb has rotted at the bottom or the opening has settled out of square, forcing a slab in is a mistake. We’ll tell you which situation you have, show you photos, and price both paths before you choose.
Kirby’s Narrow Wall Depth Problem
Many Kirby homes were framed with studded walls barely 3.5 inches deep. That’s too shallow for a standard modern pre-hung interior door, which assumes a 4-9/16 inch jamb width. We routinely shim and trim jambs to fit older Kirby walls rather than forcing a fit that leaves the casing proud of the drywall.
Door Installers in Kirby
Door installers in Kirby do more than hang a door on hinges. The real work on these older homes is in the rough opening: checking the header, measuring for rack, inspecting the bottom plate for rot, and correcting whatever’s out of true before the new unit goes in. A door installed square will close cleanly for decades. A door forced into a crooked opening will fight you every season. Typical full-frame exterior door installation in Kirby runs $1,200 – $2,800, with the reframe work driving the upper end of that range.
Exterior and Patio Door Replacement
Kirby patio doors take a beating from heat and humidity. Aluminum units from the 1960s and 70s corrode at the threshold where concrete stoops hold water. The track gets gritty, the rollers fail, and the door becomes a permanent air leak. We pull the old unit, repair or reframe the opening, and install a modern weather-stripped door with low-E glass that actually seals.
Threshold and Jamb Repairs
When the bottom of a Kirby front door frame is rusted or rotted but the rest of the unit is sound, we can often replace just the threshold and the lower jamb legs. That’s a $350 – $700 repair instead of a full replacement. The catch is that you have to look at what’s underneath first. On a home off Ackerman Road, our techs found a patio door rough opening that had settled three-quarters of an inch out of square with a rotted bottom plate from years of failed weep-hole flashing. That’s a reframe, not a repair, and we told the homeowner before we touched the saw.
Trusted Brands We Service in Kirby
We’re not locked into one manufacturer, which matters when a Kirby home needs a specific size or a specific look. We carry and install Therma-Tru fiberglass entry doors that hold up against Texas sun without warping, ViewLux doors when you want maximum glass and a clean sightline, and PGT and CGI impact-rated units for exterior openings where storm protection matters. If a Kirby customer has a product preference or an existing brand match on other doors in the house, we match it. Stock parts for common Therma-Tru and PGT hardware live on our trucks so we’re not ordering a hinge kit and making you wait a week.
Common Door Replacement Problems We See in Kirby Homes
- Rotted jambs hidden behind hollow-core casings. Kirby’s humidity works its way into unventilated utility rooms and laundry closets, rotting the bottom of interior door jambs where nobody looks until the door droops. The casing often hides it completely until we pull the trim.
- Out-of-square rough openings from slab settlement. Homes built on slab-on-grade in the 1960s settle. A door that was square when Johnson was president is now 1/2 to 3/4 inch out of rack. A replacement slab alone won’t fix it; the opening has to be corrected.
- Aluminum threshold corrosion at concrete stoops. Original concrete front stoops in Kirby trap rainwater against the door threshold. Aluminum corrodes, the seal fails, and summer cooling bills climb. We rebuild the threshold and slope the new one to shed water away from the door.
- Original jalousie or aluminum-frame door openings too shallow for modern units. Kirby homes with original aluminum door frames often have openings too shallow for a modern pre-hung door. We reframe to standard depth rather than shaving a new unit down and voiding its warranty.
Pricing for Door Replacement in Kirby, TX
Interior slab replacement in Kirby runs $450 – $900 per door installed. Full pre-hung interior units run $700 – $1,400 depending on jamb width and whether the rough opening needs correction. Exterior entry doors run $1,200 – $2,800 for a full-frame replacement with reframing, threshold work, and exterior trim. A threshold-only repair on an otherwise sound door runs $350 – $700. These are the numbers we quote in writing before anything starts. If we open a wall and find something that changes the number, you approve a written change order before we proceed.

FAQs About Door Replacement in Kirby
You can replace just the slabs if the existing jambs are square, solid, and not rotted at the bottom. We check every jamb before quoting slab work, because Kirby’s humidity rots the lower jamb legs on interior doors in unventilated utility rooms, and if the jamb is gone, a new slab won’t fix the problem. We’ll show you photos and give you both prices so you decide with the wall open, not after. Call (903) 488-7019 and we’ll take a look.
No, Kirby does not require impact-rated glazing for a like-for-like patio door replacement. But if you want a door that won’t flex in a severe thunderstorm and won’t leak air in August, an impact-rated unit from PGT or CGI is worth the upgrade. We’ll price both a standard insulated unit and an impact-rated replacement so you can compare real numbers. Call (903) 488-7019 for a free estimate.
Sometimes. If the rough opening we correct is near an outlet or a switch, the inspector may require us to bring that portion of the circuit to current code. This is common on Kirby homes built before the 1980s with two-prong outlets and no ground wire. We flag this risk in the contract before work begins, and any electrical correction is priced and approved in writing before we touch it. Call (903) 488-7019 and we’ll explain what applies to your specific door.
If the door slab is sound and the upper jambs are solid, we can replace the threshold and the lower jamb legs only, typically in the $350 – $700 range. We have to inspect the bottom plate underneath first, because Kirby’s concrete stoops hold water and the rot often extends into the floor framing. If the framing is compromised, a full pre-hung replacement is the honest fix. Call (903) 488-7019 and we’ll open it up and show you.
Interior door replacement is considered a finish trade and does not require a Kirby building permit. Exterior door replacement, when the rough opening framing is altered, may require a permit depending on the scope of the reframe. We pull permits when the work calls for them and we pass every inspection. Call (903) 488-7019 and we’ll tell you exactly what your job needs before we start.
