Fast, Reliable Door Replacement Across Leon Valley
Door replacement in Leon Valley runs $1,850 – $4,600 for a standard front entry installation and $2,400 – $5,800 for a sliding patio door, depending on whether the opening needs reframing and whether you upgrade to impact-rated glass. Juniper Windows San Antonio handles the whole job from tear-out to trim, including the aquifer-zone permitting most Leon Valley homes trigger the moment an opening changes size. We’re local to the area, we show up with a written price, and you can reach a live person anytime at (903) 488-7019.
Here’s the thing about Leon Valley: the homes are older than they look. A door that seems like a simple swap on a 1972 ranch on Bandera Road often hides an undersized rough opening, no head flashing, and a sill that’s been quietly wicking moisture into the slab for decades. We know because we’ve opened enough of them. Our Door Replacement team plans for what’s behind the trim before we ever put a blade to it.
Why Juniper Windows San Antonio Is Leon Valley’s Preferred Door Replacement Company
Leon Valley homeowners keep calling us back for one reason: the price we write down is the price we honor. Led by Sean Mackey, our crews work under a 365-Day Done Right Promise that covers parts and labor in writing for a full year after installation. If something isn’t right, we come back and fix it. No charge, no argument.
We also understand what Leon Valley specifically throws at a door. The clay soils here expand and contract through the seasons, and we’ve seen slabs drift enough to bind a door that was set plumb just twelve months earlier. Our techs check for that before ordering the unit. We’re part of the Relay Home Co. family, founded in 2001, and every Leon Valley job gets the Relay Visibility Guarantee: a live arrival time, before-and-after photos, and a digital invoice you can pay from your phone. Calls are answered by a real person 24/7, not a voicemail queue.
Door Installers in Leon Valley
Door installers in Leon Valley do something most homeowners never see: they make an old, settled opening square and watertight before the new unit even comes out of the box. That’s the part that separates a door that closes clean for fifteen years from one that starts sticking after two. We handle front entries, rear patio sliders, side doors, and porch doors across every Leon Valley neighborhood from the Bandera Road corridor to the streets off Grissom.
Reframing and Rough Opening Repair
Most 1960s and 1970s Leon Valley homes were framed for narrow doors. If you want a modern 30-inch accessible entry where a 24-inch opening used to be, the header has to come out and get replaced. We cut the drywall or brick veneer back, install a properly sized engineered header, and reflash the perimeter before setting the new door.
Same-Unit Replacement With Waterproofing
If the opening is sound, we pull the old slab, inspect the sill for rot, apply peel-and-stick membrane at the base, and set the new unit level and plumb. In Leon Valley, the inspection step matters. We’ve found missing head flashing on original 1970s installs more times than we can count, and skipping that check is how a new door starts leaking within a season.
Door Contractors in Leon Valley
Door contractors in Leon Valley are the point of contact when a project involves more than a slab swap: permit coordination, structural changes, or a door that’s part of a larger exterior upgrade. Juniper Windows San Antonio operates as your single contractor, not a middleman. We pull permits, schedule the city’s rough-in inspection, and make sure the finished opening meets Leon Valley’s current code for wind mitigation and egress.
Permit and Aquifer-Trigger Coordination
Leon Valley sits directly over the Edwards Aquifer Recharge Zone. If your door replacement changes the home’s footprint or drainage pattern, it triggers city impervious cover review and, in some cases, TCEQ aquifer-protection sign-off. We know the paperwork, we know which openings typically clear without issue, and we file everything before demo starts.
Written Change Orders, No Surprise Invoices
If the crew finds rotted framing or an undersized header during tear-out, you get a written change order with the exact added cost before we touch it. You approve it or you don’t. That’s the process, every time. Sean Mackey built the company on this because it’s the part of construction that erodes trust fastest, and he’d rather lose a job than play games with a number.
Trusted Brands We Service in Leon Valley
We’re not locked into one manufacturer, which means the right door for a Leon Valley home never has to be a compromise. We install Therma-Tru fiberglass and steel entry systems, PGT impact-rated sliding and French patio doors, and ViewLux for projects where maximum glass and minimal frame are the priority. We stock replacement weatherstripping, thresholds, and hardware locally, so a warranty follow-up or adjustment on a home near Evers Road doesn’t mean waiting on a parts truck from out of state.
Common Door Replacement Problems We See in Leon Valley Homes
- Undersized rough openings from the 1960s and 1970s. The original 24-inch swinging door opening won’t fit a modern 30-inch door without a header replacement. We find this at demo, price it as a written change order, and move forward only after you approve it.
- Sagging aluminum patio frames on slab-on-grade homes. The original 1972 sliding doors along Bandera Road are notorious for pinching at the jamb and letting water wick into the slab. A new Therma-Tru or PGT unit with proper flashing fixes the leak permanently.
- Rotted brickmould on 1980s brick veneer fronts. The door slab might still work, but water intrusion at the bottom brickmould is usually the first sign the rough opening has rot behind it. We cut back the veneer, replace any damaged framing, and reflash before trimming.
- Jalousie porch doors that can’t be repaired. If your rear porch door has the original jalousie louvers, replacement hardware hasn’t been manufactured in decades. We convert the opening to a French door or single swing unit that seals tighter and actually locks.
Pricing for Door Replacement in Leon Valley, TX
Front entry replacement in Leon Valley typically lands between $1,850 and $4,600 installed. Sliding patio doors run $2,400 to $5,800, with the higher end covering impact-rated glass and reframing. A French door conversion from a jalousie rear porch opening usually falls between $2,900 and $5,200 depending on the header work.
What moves the number: the size of the opening, whether the header needs replacing, whether you choose fiberglass, steel, or impact-rated glazing, and whether the city requires an aquifer-zone review. We write every line item down before work starts and the quote is free. Call (903) 488-7019 and we’ll schedule a time to measure and give you a real number.

FAQs About Door Replacement in Leon Valley
If the door opening stays the same size and you’re not altering drainage or expanding any impervious surface, most replacements clear without a full aquifer review. You’ll still need the standard city building permit. We file that paperwork as part of the job. For an exact read on your specific home, call (903) 488-7019 and we’ll tell you what applies before you commit to anything.
Because the original 1960s and 1970s units were installed without head flashing and with narrow rough openings. By the time a door is sagging, leaking, or binding, the framing behind it usually has rot or has settled out of square. Replacing just the slab almost never fixes the root cause, and in many cases the original hardware isn’t made anymore. We’ll always tell you what’s actually failing before quoting repair versus replacement. Call (903) 488-7019 for a free inspection that separates the two clearly.
Yes, in most cases. The jalousie opening is usually wide enough to accept a French door unit as long as the header above it is sound. If the header is undersized or rotted, we replace it from below without touching your roofline. The conversion typically takes two to three days including the city’s rough-in inspection. For a precise quote on your porch opening, call (903) 488-7019.
It’s real, but the savings depend on what you’re replacing. Original single-pane aluminum doors are essentially holes in your thermal envelope. A Therma-Tru insulated fiberglass unit with low-E glass reduces that heat gain measurably, especially on west-facing entries that take the full Leon Valley afternoon sun. The bigger win is comfort: rooms adjacent to the old door stop feeling like ovens from mid-June through September. We’ll be direct about what to expect rather than inflating a number.
The honest answer depends on what’s behind the brickmould. Rot at the bottom is often surface-level and just needs new moulding and sealant. But on slab-on-grade Leon Valley homes, water that reached the brickmould often also reached the sub-sill and bottom of the jamb. We’ll pull the moulding, inspect what’s underneath, and show you what we find before recommending anything. If it’s just the moulding, that’s a minor repair. If the rough sill is spongy, you’ll want a new door with proper flashing. Call (903) 488-7019 and we’ll give you a straight read.
