Fast, Reliable Door Installation Across Austin
Door installation in Austin runs anywhere from $900 for a basic slab swap to $14,000+ for a custom impact-rated sliding glass wall, and most jobs land between $1,800 and $4,500 installed. We’re Westlight Windows Austin, part of the Kingswell network of independently owned locations, and we’ve been installing doors since 2009. Our crews work everywhere from Mueller to Circle C to Crestview, handling the city’s odd mix of 1970s aluminum sliders and brand-new infill builds that sit on the very same block. Call (254) 322-3468 for a written price before any work starts.
Why Westlight Windows Austin Is Austin’s Preferred Door Installation Company
People in Austin have been let down by contractors before. The no-show. The price that jumps when the crew arrives. The door that sticks six months later and the company that’s vanished. We built Westlight Windows Austin to be the opposite of that. Owen Satterfield runs things, and his approach is plain: answer the phone, show up in the window we gave, and put every price and every promise in writing before a single screw turns.
Our installers are background-checked and uniformed, so you know who’s walking through your door. Every job gets the Kingswell Guarantee: a written price up front, a committed arrival window, a clean job site, and a written guarantee handed to you when the work is done. If something fails within the guarantee period, we come back and fix it at no charge. That’s not a sales pitch; it’s the 365-Day Done Right Promise, and it’s issued on paper for every door we install in Austin.
We carry eight manufacturer lines, so when a homeowner in Tarrytown needs a fiberglass entry door that looks like wood but won’t rot in Austin humidity, we spec Therma-Tru instead of forcing a vinyl door that doesn’t belong on the house. When a family in Georgetown asks about impact glass, we show them PGT and CGI side by side and explain the difference in Miami-Dade NOA ratings. That’s the whole point of carrying eight lines: the right product matched to the job, not the job forced to fit one brand. Our Door Installation team does this every single week.
Door Replacement in Austin
Door replacement in Austin isn’t a one-size-fits-all job. The city’s explosive growth left a patchwork of 1970s-80s suburban homes alongside modern infill, meaning our crews regularly encounter everything from single-pane aluminum sliders baking in the afternoon sun to oversized, energy-code-driven Low-E packages in new builds, often on the same street. When you replace a door here, the question isn’t just “what fits the opening” but “what stands up to 100-degree heat, 90% humidity, and a hailstorm in April.”
What the Job Involves
A standard door replacement in Austin runs $1,200 to $3,800 for a mid-range entry unit, installed. That includes removing the old door, setting the new pre-hung unit, insulating and sealing the rough opening, and hauling away the old door. If the jamb is rotted or the subfloor has water damage from decades of Austin thunderstorms, we’re up front about that cost before we start, not after.
Signs You Need Replacement
You can see daylight around the edges. The door has swollen so badly it won’t latch in summer. The frame is soft at the bottom from splash-back on a concrete stoop. Or the sliding glass door has failed seals and you can feel heat radiating through the glass. In Austin, doors take a beating from the sun and humidity, and by the time you notice the draft, the frame often needs work, not just the slab.
Sliding Glass Door Replacement in Austin
Sliding glass door replacement in Austin is one of the most common jobs we do, because so many homes here were built in the 1980s and 1990s with aluminum-frame sliders that are now failing. A typical sliding glass door replacement in Austin runs $2,200 to $6,500 depending on size, glass package, and whether the opening needs a new frame. The good news: a well-installed modern slider with low-E glass (a thin coating that reflects heat back outside in summer) will cut your cooling bill and actually glide when you open it.
Why Austin Sliders Fail
Aluminum frames expand in the heat. Rollers collect dirt and grit. The tracks get bent when someone forces a stuck panel. The end result is a door you can’t lock, a door that lets in the humid air, and a door that’s a security risk because it won’t fully close. We reinforce the jamb before installing a new unit, and we use heavy-duty rollers rated for the weight, not whatever came in the box.
What Your Options Are
If the frame is solid, you may be able to replace just the door panel and hardware. But if the frame is warped from Austin’s humidity or the original install wasn’t flashed properly, you need a full frame replacement. We’ll tell you which one you need, and we’ll tell you why. The price we quote is the price on the invoice, period.
Trusted Brands We Service in Austin
We install and stand behind Therma-Tru, PGT, and CGI doors, among our eight manufacturer lines. Therma-Tru is our go-to for entry doors that need to look like real wood but handle Austin’s moisture without swelling. PGT and CGI are the names we pull out when a homeowner on the west side or in a hail-prone pocket of Round Rock wants impact-rated glass with Miami-Dade documentation that satisfies both the building inspector and the insurance underwriter. We keep local stock access for Austin jobs, so a standard replacement doesn’t stall waiting on a freight truck from Florida.
Common Door Installation Problems We See in Austin Homes
- Aluminum sliding panels that bind in the heat. As the frame expands in July, the door seizes and the lock won’t engage. We reinforce the jamb and replace worn rollers before the first heat wave hits, so the door locks when it matters.
- Custom orders that stall on glass lead times. An architect specifies a high-performance package that isn’t stocked locally. Lead times on custom glazing for Austin infill projects run 12 to 16 weeks, and we lock that schedule and price in writing before we order, so you don’t tear out a door and live with plywood for three months.
- Designer doors without NOA documentation. A beautiful door picked from an online catalog arrives with no Miami-Dade NOA. The building official in Austin won’t sign off, insurance won’t credit the wind mitigation, and you’re stuck. We pre-vet every NOA before ordering.
- Failed seals and warped frames on 1980s sliders. Austin humidity wrecks aluminum frames over 30 years. Sometimes the panel can be swapped; other times the whole frame is shot and needs a fresh start with proper flashing and insulation.
In East Austin’s Holly neighborhood, our crew replaced a failing 1950s wood double-hung entry door with a Therma-Tru fiberglass unit, preserving the original wavy glass sidelights by routing custom jamb liners to accept the thicker modern insulated glass unit. The homeowner had been living with warped jambs and a sagging sash that let in the humid air, so we reset the frame with a reinforced sill and specified a low-E, impact-rated glazing package to cut the afternoon heat gain. That’s the kind of work Austin asks for, and it’s the kind we like doing.
Austin’s housing stock is the real story here. Drive through Crestview or Allandale and you see 1960s ranch homes with original doors that predate energy codes. Cross 620 into Steiner Ranch and you get early-2000s builds with large glass areas now failing at the seal. Head into the new infill off South Lamar and you see floor-to-ceiling glass packages that never would have been built here 20 years ago. The same door company has to know all three. We do. Door Installation in Austin is what this page is about, and it’s the work we do every day.

FAQs About Door Installation in Austin
The wavy glass stays in place. We route custom jamb liners to accept a thicker insulated glass unit beside the original panels, so the historic character remains while the door assembly meets modern impact and energy standards. It costs more than a standard replacement: budget $3,000 to $5,500 for a bungalow entry upgrade with preserved original glass and an impact-rated package. Call (254) 322-3468 and we’ll tell you if your specific door can carry that glass.
Yes. PGT impact-rated products are engineered to take a direct impact from a 9-pound 2×4 traveling at 50 feet per second and keep the glass in the frame, which is the Miami-Dade test standard. Austin hailstones don’t move at that velocity, so you’re well covered. A PGT sliding glass door in a standard 6-foot opening runs $3,800 to $7,000 installed, with the NOA documentation your insurance company wants to see for a wind mitigation credit.
Custom doors require custom glass packages. Low-E coatings, impact laminates, oversized panels, and specific finishes are made to order, and the glass manufacturers in the supply chain have production queues. Standard doors are stocked and ship the same week. We lock the lead time and the material price in writing before you schedule demolition, so nobody tears out a door and waits months with a gap in the house.
It depends on the condition of the frame. If the jamb is solid and only the panel and hardware need attention, we replace the panel. If the frame is bowed, the threshold is rotted, or the original flashing was installed wrong, you need a full frame replacement. We inspect first and tell you which one is actually necessary. A panel-only swap runs $1,500 to $3,200; a full frame replacement runs $2,800 to $5,500 in Austin.
You need the product’s Miami-Dade NOA (Notice of Acceptance) or Texas Department of Insurance windstorm documentation, plus a copy of the installation contract showing the product was installed to code. We pre-vet every NOA before ordering and provide the paperwork at job completion, along with the written guarantee. Call (254) 322-3468 for a free estimate, and we’ll walk you through what your specific home needs.
