Therma-Tru Door Installation: The San Antonio Owner’s Guide
Therma-Tru door installation in San Antonio typically runs $450 – $1,850 depending on whether we’re rebuilding an existing frame, replacing weathered weatherstripping and sweeps, or hanging a brand-new pre-hung unit. We stock Therma-Tru-compatible hinges, thresholds, door sweeps, weatherstripping, and multipoint lock hardware on our trucks, so most service calls wrap up in a single visit. The way most San Antonio homeowners discover a failing part is subtle: the door starts sticking in August’s humidity, or you notice daylight creeping under the threshold at dusk.
Which Therma-Tru Models This Applies To
We work on every Therma-Tru line you’re likely to have in a San Antonio home: Classic-Craft, Smooth-Star, Pulse, and the fiberglass and steel entry systems under the Therma-Tru name. The gotcha most owners miss: Therma-Tru’s single- and double-bore hinge prep is standard, but the adjustable threshold cap on Smooth-Star is taller than the Classic-Craft’s, so a universal threshold from a big-box store often leaves a 1/8-inch gap at the sweep. We verify the part by the white Therma-Tru label on the hinge edge of the slab, then match it to the correct OEM or equivalent aftermarket part. OEM is worth it on anything that touches the weather seal; a quality aftermarket hinge is fine when the geometry matches.
Signs Your Therma-Tru Door Installation Is Failing
- The door drags at the top or latch side when it didn’t before. This usually means the top hinge has sagged, or the frame has shifted from San Antonio’s expansive clay soils moving through wet-dry cycles.
- You feel air at the bottom even with the threshold adjusted all the way up. The door sweep has flattened or torn, and the threshold cap has worn through its channels. That’s a $40 – $90 fix if we catch it before water intrusion starts.
- Deadbolt won’t throw without lifting the handle. Misalignment between slab and frame, often caused by a hinge that’s lost its screws’ bite. We see this regularly in Alamo Heights homes where original installs used short screws.
- Daylight or water staining at the top corner. Flashing failure at the cap, or the jamb has wicked moisture because the drip edge was never seated right. This is the one that turns into rot if left alone through a wet spring.
- You hear rattling when the door closes. Loose weatherstrip retention or a threshold that’s lost its fasteners. Easy fix for us, annoying forever if it’s ignored.
Replacement Cost & What’s Included
Here’s what we quote in San Antonio, and it’s a written number before any work starts:
- Door sweep or threshold cap replacement: $65 – $140 installed
- Full weatherstripping and sweep refresh: $110 – $250 installed
- Hinge replacement or screw repair on an existing slab: $150 – $390 installed
- Frame repair and re-hang of your existing Therma-Tru slab: $350 – $800 installed
- New pre-hung Therma-Tru unit installed (standard single entry): $900 – $1,850 installed, depending on the exact model and whether the rough opening needs work
The price you get covers the part, labor, and cleanup, with no change-order surprise at the end. Every Therma-Tru installation we complete is covered by the 365-Day Done Right Promise: if something isn’t right, parts and labor, we come back and make it right within the year. That’s in writing on every invoice.
DIY or Call Us?
You can safely replace a screw-on door sweep or clean the threshold track yourself. Those are ten-minute jobs and they don’t affect how the slab sits in the opening. What I’d tell you not to touch: anything involving hinge mortising, re-shimming the jamb, or digging into flashing. A door that’s even 1/16 inch out of plane will fight you forever, and unlike a window, you can’t just caulk the problem away. If the door is dragging, the fix often means pulling the slab and resetting hinge screws into solid framing, which is straightforward for us and frustrating for a Saturday DIYer. Call (903) 488-7019 and we’ll tell you straight if it’s worth a service call.
FAQs
Door sweeps and weatherstripping usually last 5 – 7 years in San Antonio’s sun and heat, and thresholds can go 10 – 15 if the sweep is maintained. The biggest killer here is UV: rubber and vinyl seals dry out and crack faster on west-facing doors than the manufacturer’s average. Sean Mackey has pulled sweeps in Terrell Hills that looked baked brittle in under four years because the afternoon sun never let up.
Weatherstripping, sweeps, and hinge screws are repair-first items. A rotted jamb leg or a slab with a de-laminated corner typically needs replacement, not patching. We’ll give you the honest answer on the first visit, and the repair is backed by our 365-Day Done Right Promise. Call (903) 488-7019 for a free estimate.
A sweep, threshold, or hinge job is done in under two hours. A full pre-hung door replacement in San Antonio usually takes four to six hours from removal to final trim and cleanup. If the rough opening needs framing correction, we’ll tell you that in the written quote before we start.
We stock common Therma-Tru-compatible sweeps, thresholds, weatherstripping, hinges, and multipoint lock hardware on our trucks. We also carry parts for PGT, CGI, CWS, and other product lines we service, so the fix usually happens in one trip. For less common items, we source OEM and have it within two to three business days.
If you’ve got a Therma-Tru door that’s dragging, leaking air, or just doesn’t close like it used to, call (903) 488-7019 for a free estimate. We’ll give you a written number before any work starts and back the installation with the 365-Day Done Right Promise.
