Why Juniper Windows Austin Is Lost Creek’s Preferred Door Replacement Company
Most Lost Creek homeowners we meet are dealing with the same set of problems: original aluminum sliders that won’t roll, fogged glass in west-facing fixed panels, and frames that have racked out of square as foundations settle on the slopes. We know how to fix all three because we’ve done it on dozens of homes here. Sean Mackey runs our crew, and he’s built the Lost Creek operation around one thing: showing up when we say we will and putting the price in writing before the first screw turns.
The Door Replacement team at Juniper Windows Austin is part of the Relay Home Co. family, founded in 2001. Every Lost Creek job gets a written price upfront, a background-checked uniformed technician, and the 365-Day Done Right Promise covering parts and labor in writing. If something isn’t right a full year later, we come back and make it right. No charge, no argument. We also answer the phone 24/7 with a live person, not a voicemail tree. That matters when a door won’t latch at 10pm and you need to talk to someone who can diagnose the issue.
We’re not a franchise. We’re an independently owned location operating under The Relay Visibility Guarantee: a live arrival time you can track, before-and-after photos of every job, and a digital invoice you can pay from your phone. Lost Creek customers get the same transparency you’d expect from a rideshare app, only we’re hauling a level and a saw instead of a car.
Door Contractors in Lost Creek
Door Contractors in Lost Creek handle everything from swapping a single French door to replacing every exterior opening on a custom ridge-top home. Here, that work almost always involves county permitting, custom sizing for irregular openings, and installation on uneven terrain that only looks flat from the street. If you’re noticing a door that sticks, sags, or lets daylight through the weatherstripping, that’s the moment to call before water gets under the threshold and rots the subfloor.
County Permitting and Septic Setbacks
Lost Creek sits in unincorporated Travis County, not inside Austin city limits. That changes everything about how door replacement gets permitted. Travis County issues the permits, not the City of Austin, and the inspection process runs on a different clock. For homes on septic and well, we also have to verify that a new door opening or a widened rough opening won’t encroach on required setbacks from the drain field or the wellhead. This is not a box a generic crew checks. We check it on every Lost Creek quote because encroaching on a septic setback can create a serious code violation and an expensive remediation.
Sloped Lots and Custom Openings
Most Lost Creek homes were built into hillsides, which means the subfloor under a door is rarely level, and the rough opening is often half an inch out of square in two directions. A big-box replacement doesn’t account for that. We measure every opening in three dimensions, shim to true, and flash thresholds so rainwater runs away from the house instead of under it. On steep lots, that’s the difference between a door that seals for 20 years and one that rots the subfloor in five.
Door Frame Repair in Lost Creek
Door Frame Repair in Lost Creek usually means one of three things: a frame that’s racked from foundation settling, a threshold that’s rotted from improper flashing, or a jamb split by a door that’s been forced open after the lock misaligned. Each one is fixable without tearing out the whole wall. The cost typically falls between $350 and $1,200 depending on how much of the frame has to be rebuilt and whether the rough opening needs re-shimming.
Racked Frames on Sloped Foundations
Foundation settling is a fact of life on Lost Creek’s hillsides. When a foundation shifts, door frames go out of square and the door starts binding at the top corner or dragging on the threshold. We reset the frame, shim it to true, and replace hinges and strike plates as needed. Sometimes that’s all it takes. Other times the slab has moved enough that we need to trim the door edge and adjust the reveal so it swings clean.
Threshold Rot and Water Wicking
The most common frame failure we see on Lost Creek’s sloping lots is a threshold that was never flashed correctly. Rainwater wicks under the metal and sits against the wood subfloor, and by the time the door starts sticking, the rot is usually worse than it looks from the top. We cut back to solid wood, rebuild the saddle, and flash it with adhesive membrane that ties into the house wrap. Then we test it with a hose before we call it done.
Trusted Brands We Service in Lost Creek
We install and service PGT, ViewLux, and CGI doors, and we stock common replacement parts for all three lines so Lost Creek customers don’t wait weeks for a roller, a hinge, or a weatherstrip. PGT’s impact-rated sliders are a strong match for the west-facing doors all over Lost Creek, because the laminated glass interlayer holds together under wind-borne debris and cuts a meaningful amount of heat gain. ViewLux gives us elegant sightlines on homes where the Hill Country view is the whole point of the house. CGI doors are the right call for anyone who wants a heavy-duty door without giving up a clean exterior line.
Common Door Replacement Problems We See in Lost Creek Homes
- Seized sliders on west-facing patios. Original aluminum patio doors in Lost Creek face west toward the Hill Country views, and those doors have been cooking in the afternoon sun for 40 years. Rollers seize from heat expansion, frames rack from foundation settling, and the door becomes impossible to open without lifting the whole panel.
- Fogged insulated glass units. Intense UV exposure breaks down the seal on dual-pane glass in large fixed panels, and once argon leaks out and moisture gets in, the glass fogs. You can’t buff it out – the IGU has to be replaced.
- Flash failures on sloped entries. On a hillside, water flows downhill. A door flashed like it’s on a flat Dallas lot lets rainwater under the threshold, and the subfloor rots from inside. This shows up as a door that suddenly starts sticking or sagging after a wet spring.
- Racked frames from moving foundations. Lost Creek’s clay-rich soil expands and contracts with moisture, and slabs on slopes move more than slabs on flats. That movement puts stress on door frames, and eventually the door won’t latch or the deadbolt won’t throw without yanking the handle.
Pricing for Door Replacement in Lost Creek, TX
A single exterior door replacement in Lost Creek runs $1,800 to $6,400 installed. That includes the door slab, frame, hardware, trim work, flashing, and haul-away. Sliding patio doors run $2,900 to $9,800 depending on width, glass package, and whether the track and subfloor need repair. French door sets fall between $3,500 and $8,500. The big cost drivers in Lost Creek are custom sizing for non-standard openings, county permit fees and inspection scheduling, septic and well setback verification when openings change, and the extra labor of working on a slope.

FAQs About Door Replacement in Lost Creek
No. Lost Creek is in unincorporated Travis County, so door replacement permits come from Travis County, not the City of Austin. The process is different from an Austin city permit, and inspection timing runs on the county’s schedule, not the city’s. Our crew handles that paperwork as part of the job. If you’re changing the size of an opening or adding a new exterior door, the permit is more involved, and we’ll verify septic and well setbacks before we pull it. Call (325) 420-1750 and we’ll tell you upfront what your specific project needs.
Yes, in most cases, as long as the new opening doesn’t encroach on the minimum setback from your septic drain field or your wellhead. On some Lost Creek lots, that setback is the limiting factor, not the wall you’re cutting into. We check the septic as-built and the well location on every quote that involves a new opening or a widened rough opening, and we’ll flag the issue before you spend a dollar. Call (325) 420-1750 with your address and we’ll walk you through it.
Heat expansion and foundation settling are the two culprits on most Lost Creek homes. The original aluminum rollers seize from decades of afternoon sun, and the frame racks as the slab shifts on the slope. Once the rollers are seized, the door drags, and eventually the panel jumps the track. The fix is usually new adjustable rollers, a cleaned or replaced track, and re-shimming the jamb so the door runs square. Call (325) 420-1750 and we’ll send a technician out to diagnose it in person.
No, not if we spec the door correctly. Many Lost Creek homes have expansive west-facing glass specifically to capture the Hill Country view, and the right replacement preserves that sightline. PGT and ViewLux both make slider configurations with narrow stiles and rails that maximize glass area, and we can match the original opening size in most cases. If you’re replacing a patio door on a view-facing wall, tell us on the phone and we’ll bring sample doors with full sightline measurements. Call (325) 420-1750 for a free estimate.
It depends on your exposure and what you’re protecting. Lost Creek is not in a hurricane zone, but it is in Hill Country hail and storm territory, and impact-rated glass from PGT or CGI is built to resist wind-borne debris without shattering. Many Lost Creek homeowners choose impact-rated sliders on west-facing walls because those walls take the brunt of spring storms. It’s not required by local code in Lost Creek, but it’s a reasonable upgrade if you want extra protection. Call (325) 420-1750 and we’ll give you an honest recommendation for your specific lot and orientation, plus a written quote either way.
On a 1980s ridge-top home off Lost Creek Boulevard, Sean Mackey and our techs replaced three original aluminum sliding patio doors facing west with PGT impact-rated sliders using laminated glass interlayers. The old rollers had seized from heat expansion, and the frames were racked from foundation settling on the slope. We installed new jambs and sashes with adjustable rollers, restored smooth operation, and added Low-E glass to cut the afternoon heat gain without blocking the Hill Country view. That job took two days, and the homeowner has been able to use those doors every day since.
If you’re in Lost Creek and you’re tired of fighting a door that sticks, sags, or won’t lock, call (325) 420-1750. Ask for a free estimate. We’ll give you a written price, a clear timeline, and a door that works the way it should have for the last 40 years.
