AfterTherma-Tru Door Installation: The Fountainebleau Owner’s Guide
Therma-Tru door installation in Fountainebleau typically costs $850 to $2,400 for a full replacement, depending on the slab size, frame condition, and hardware. We stock Therma-Tru-compatible slabs, frames, weatherstripping, thresholds, and hinge systems, and most installations are completed in a single visit. The way most Fountainebleau homeowners discover they need this work is gradual: a door that suddenly drags against the jamb, daylight sneaking in around the weatherstrip, or a deadbolt that no longer lines up with the strike plate. By the time you’re fighting the door every morning, the frame has usually shifted or the slab has absorbed enough South Florida humidity to lose its original dimensions.
Winslow Windows & Doors is an independent installer, not a Therma-Tru company. That matters because we can source the right part without dealer markup, and we install it the way Therma-Tru engineered it to sit. If you’re in Fountainebleau and your Therma-Tru door isn’t closing like it used to, call (727) 620-6983 and we’ll tell you honestly whether it’s a part swap or a full rehang.
Which Therma-Tru Models This Applies To
Therma-Tru makes doors across several series, from the Smooth-Star and Fiber-Classic fiberglass lines to the Classic-Craft and Pulse collections. The compatibility gotcha most owners hit is that frame parts are not universal between series. A weatherstrip set cut for a Smooth-Star slab won’t seat correctly on a Classic-Craft frame, and threshold profiles differ by up to 3/8 inch between models. We identify the right part by pulling the manufacturer label on the hinge edge of the slab. If that label is faded or painted over, we measure the slab thickness (typically 1-3/4 inches, occasionally 1-3/8 on older models), the jamb depth, and the sweep profile.
On the OEM-versus-aftermarket question: Therma-Tru OEM weatherstripping and thresholds are worth the extra cost because they’re matched to the specific kerf cuts and corner geometries of each series. For slabs and frames, OEM is the safest route for Classic-Craft wood-grain finishes where color matching matters. For hardware like hinges and bottom sweeps, quality aftermarket equivalents from brands we also work with, including PGT, CGI, and CWS, perform identically and save real money. Ed Winslow will walk you through which parts justify OEM and which don’t, before anyone touches a screwdriver.
Signs Your Therma-Tru Door Installation Is Failing
- Daylight visible around the door perimeter. This means the weatherstripping has compressed beyond its recovery point or the slab has sagged out of alignment. In Fountainebleau’s humidity, compressed weatherstrip is usually a humidity-swollen jamb pinching the seal, not just wear.
- The door scrapes against the jamb or threshold. Fiberglass skins expand and contract with moisture. A slab that fit perfectly in January may drag by August. If the hinge screws haven’t pulled loose, the fix is often a threshold adjustment, not a new door.
- The deadbolt or latch no longer lines up. When you have to lift the handle to lock the door, the hinge pack or the frame has shifted. Running a 3-inch screw through the top hinge into the framing may buy you time, but if the frame has twisted, an Fountainebleau installation team needs to look at it.
- The bottom sweep is torn, brittle, or missing. South Florida sun and rain destroy bottom sweeps faster than any other component. A torn sweep lets in water, bugs, and air-conditioned air, and it’s the cheapest part to fix before the threshold underneath starts corroding.
- The door won’t stay open or won’t stay closed. A door that drifts on its own has either a frame out of level or a hinge pack that’s worn. In older Fountainebleau homes with settling slabs, this is the first sign that the frame needs to be re-shimmed.

DIY or Call Us?
Replacing a bottom sweep or tightening hinge screws on a Therma-Tru door is a job an Fountainebleau homeowner with basic tools can handle. Weatherstrip that slides into a kerf is also manageable if the old strip comes out cleanly. What is not DIY territory: anything involving the frame, the threshold anchoring, or a slab that’s heavier than you expect. A Therma-Tru fiberglass slab with a full polyurethane core weighs upwards of 100 pounds, and hanging one so the margins are even and the weatherstrip seats correctly takes experience, not just strength. We’ve re-hung doors in Fountainebleau after DIY attempts that left the reveals off by half an inch, and the owner paid twice: once for the parts, then for the correction.
If your door is dragging, leaking, or not locking, call (727) 620-6983 and Ed or one of our technicians will walk you through what we’d check first. The second opinion is free. If it’s a ten-minute fix we’ll tell you how. If it’s a frame issue, you’ll want us on it.
FAQs
A correctly installed Therma-Tru door unit should perform for 20 to 30 years in Fountainebleau’s climate, though weatherstripping and bottom sweeps typically need replacement every 4 to 7 years due to sun exposure and humidity cycles. The slab itself is fiberglass and won’t rot like wood, but the frame, if exposed to standing water or poor drainage, can fail much sooner. Call (727) 620-6983 and we’ll assess your specific door’s condition and give you an honest lifespan estimate.
Yes, in most cases the door slab is fine and the problem is weatherstripping, a threshold, hinge screws, or frame shimming, all of which we repair for a fraction of a full unit cost. Full replacement only makes sense when the slab itself is damaged, the frame has rotted, or you’re upgrading for impact or energy reasons. Call (727) 620-6983 and we’ll tell you which category your door falls into.
A weatherstrip or threshold replacement takes 45 to 90 minutes. A full unit swap is usually a single visit of 3 to 5 hours, including removing the old frame, setting the new one, hanging the slab, and hauling away the debris. We bring the parts on the truck based on the measurements we take during the estimate, so we’re not making you wait through a second appointment.
We stock Therma-Tru-compatible weatherstripping, thresholds, bottom sweeps, and hinge hardware for the most common series, so most repairs happen the same day. For full slabs and frames in specific styles or sizes, we order from our Therma-Tru supplier and typically have the unit in hand within 5 to 10 business days. Call (727) 620-6983 with your model information and we’ll confirm availability before you schedule.
