AfterTherma-Tru Door Installation: The Palm Beach Owner’s Guide
We stock and install Therma-Tru door components across Palm Beach, with most replacement parts installed for between $240 and $680 depending on the part and your door model. If you call before noon on a weekday, we can usually have a technician at your Palm Beach home the same day with the right piece on the truck. The way most owners find us is simple: the door worked fine for fifteen years, then one afternoon it started dragging, sticking, or letting daylight through where it shouldn’t. Therma-Tru builds a solid door, but salt air and Florida humidity have a way of finding every weak point.
Which Therma-Tru Models This Applies To
We work on the full Therma-Tru lineup you’ll actually find in Palm Beach: Classic-Craft, Fiber-Classic, Smooth-Star, and Pulse series doors. The compatibility catch most people don’t know until they’re standing in front of a door that won’t close is this: Therma-Tru uses different hinge mortises and sill profiles across these lines, and a part that fits a Smooth-Star won’t always seat properly on a Classic-Craft. We identify the right part two ways: by the sticker on the door’s hinge edge (Therma-Tru prints the series and manufacture date there, though after ten Florida summers it’s often faded to nothing) and by measuring the slab thickness and the sill cap profile. If the sticker’s gone, our technicians pull measurements and match against the original spec, no guesswork. On the OEM-versus-aftermarket question: for weatherstripping, door bottoms, and sill caps, quality aftermarket equivalents often perform as well as the branded part and cost less. For hinges and the multi-point locking hardware, we stick with Therma-Tru OEM or one of two aftermarket lines we’ve tested over the years. We’d rather tell you the part costs $40 more than come back in eight months because the cheaper lock set didn’t hold adjustment.
Signs Your Therma-Tru Door Installation Is Failing
- Daylight visible under the door even when it’s latched. The bottom sweep or the sill cap has worn or compressed. This is the number one failure we see in Palm Beach, where sun exposure bakes the vinyl sweep brittle, then the seasonal humidity swings finish it off.
- The door binds or drags at the top corner. Hinges have settled or the frame has shifted slightly. Therma-Tru doors are heavy, and once the hinge screws start working loose in the jamb, the door migrates downward and starts eating the sill.
- You have to lift the handle or shoulder the door to get the latch to engage. The lock set has drifted out of alignment, usually because the strike plate moved or the weatherstripping swelled and is pushing the slab off plane.
- Condensation or fogging between the glass in the door lite. The insulated glass unit has lost its seal. It’s not a cosmetic issue; once the argon or krypton fill is gone, that lite is no longer doing its energy job, and in Palm Beach humidity it may also start holding moisture permanently.
- A draft you feel standing near the closed door on a windy afternoon. Usually the perimeter weatherstripping has flattened or the corner pads have disintegrated. It’s the part that fails first on almost every Therma-Tru door we open up.
Replacement Cost & What’s Included
Here’s what a Palm Beach homeowner can expect to pay in 2026. These prices include the part and our labor, with no surprise line items on the bill:
- Bottom door sweep replacement: $90-$180 installed
- Weatherstripping (full perimeter): $140-$260 installed
- Sill cap replacement: $220-$420 installed
- Hinge replacement and door realignment: $180-$340 installed
- Multi-point lock set replacement: $320-$520 installed
- Insulated glass lite replacement: $280-$680 installed
The range depends on your door’s series and age, because older Therma-Tru models sometimes require a retrofit part that’s no longer in the catalog. Every quote is fixed before we start work, written, including both the part and the labor. The Done Right Promise covers the workmanship. If the part has its own manufacturer warranty, we register that in writing and tell you how long it runs, the way The Keystone Standard says we should.
DIY or Call Us?
You can safely inspect the sweep and perimeter weatherstripping yourself: close the door, look for daylight, run your hand along the edges for drafts. If you find the sweep is hard and cracked, call us and we’ll match it. What we’d caution against is trying to replace door hinges, sill caps, or any part of the locking hardware on your own. A Therma-Tru slab with the glass lite in it can weigh 80 to 130 pounds depending on the series, and once you pull the hinge pins, that weight is entirely on you. It takes one slip to crack the glass, damage the threshold, or worse. We’ve also seen homeowners use the wrong screw length on hinge replacements and split the jamb. If the part is mechanical, holding weight, or keeping the door secure, give us a call at (850) 801-5596 rather than making the job bigger than it started.
FAQs
Most Therma-Tru weatherstripping lasts 5 to 9 years in Palm Beach before the combination of sun, salt air, and humidity compresses it enough to let air through. Your door’s exposure matters: a south-facing entry with no overhang will eat through a sweep in 3 to 4 years, while a shaded covered entry can go 10 or more. Call (850) 801-5596 and we’ll tell you honestly whether yours is dead or still has life in it.
Weatherstripping and sweeps are always replacement parts; there’s no meaningful way to repair compressed vinyl or worn pile. Hinges can sometimes be tightened and realigned rather than replaced, but once the knuckle is worn or the leaf is bent, replacement is the only fix that lasts. For the exact answer on your door, we’ll look at it and tell you straight; estimates are free.
Most sweeps, weatherstripping, and hinge replacements take 45 to 90 minutes start to finish. A sill cap replacement runs about two hours, and a multi-point lock set can take two to three hours depending on the door’s age and adjustment needs. We carry the common Therma-Tru parts on the truck, so most jobs are done in a single visit. Call (850) 801-5596 to schedule a time when we’ll actually show up.
Our trucks carry the common failure parts for Therma-Tru doors: sweeps, perimeter weatherstripping, hinge sets, and the standard multi-point lock components for Classic-Craft and Smooth-Star doors. For obscure parts on older models, we order direct and usually have them in hand within 3 to 5 business days. We also keep common parts for PGT, CGI, and CWS doors if you have one of those in the house too. Call (850) 801-5596 with your door’s model or a photo of the sticker and we’ll tell you what we’ve got on the truck that day.
