AfterTherma-Tru Door Installation: The Little Gables Owner’s Guide
Installed Therma-Tru door hardware and component replacement in Little Gables typically runs $185 to $480 depending on the part, finish, and door series. We stock the most common failure points on our trucks, so most jobs are finished in a single visit. Owners usually discover the problem the hard way: a deadbolt that binds, a sweep that’s left a water stain on the tile, or a threshold that catches the door every time it swings.
Which Therma-Tru Models This Applies To
Therma-Tru’s main residential lines in South Florida are the Classic-Craft, Fiber-Classic, and Smooth-Star series. The compatibility gotcha that trips people up: Classic-Craft doors use a thicker door slab than Fiber-Classic, which means the hinge mortises and bottom sweep dimensions are not interchangeable between series. If you can’t find your model name, look for a small white label on the hinge edge of the slab, or measure the door thickness. Classic-Craft feels like a true 1-3/4-inch door; Smooth-Star runs closer to 1-5/8. We install OEM Therma-Tru parts when they make sense, and for things like weatherstripping and sweeps we also carry aftermarket equivalents that meet or beat the original spec. Winslow Windows & Doors is an independent installer, not affiliated with Therma-Tru, and we also work on PGT, CGI, and CWS door hardware.

Signs Your Therma-Tru Door Installation Is Failing
- You have to lift or shove the door to get it to latch. Almost always the threshold has settled or the hinges are wearing. In Little Gables this is common in older homes where the slab has shifted over decades of wet-dry soil cycles. The fix is usually re-shimming and a new threshold cap, not a whole new door.
- The bottom sweep is cracked, sagging, or gone. Florida heat and humidity break down rubber and vinyl quickly. A rotted sweep lets water and insects in, and in Little Gables during rainy season you’ll see the evidence inside within a month.
- The deadbolt or handle turns but doesn’t throw the bolt. This is the gearbox inside the multi-point lock mechanism. The internal gears strip, especially on doors that see ten uses a day. The door slab itself is usually fine.
- The door scrapes or drags at the strike side near the bottom. Hinge sag, or the frame has shifted. In pre-1960s Little Gables houses with original framing, this is common and fixable without replacing the door.
- The weatherstripping is flat, torn, or gone along the sides. You’ll feel the draft before you see it. Interior humidity creeps up, the AC works harder, and your electric bill tells the story.

Every quote includes the part, labor, disposal of the old component, and a function test of the full door. You’ll get a written line-item estimate before any work begins. Ed Winslow grew up in Little Gables not far from the old Coral Gables Congregational Church, and he still lives a few miles from where he learned to ride a bike. He’s been measuring, installing, and standing behind doors in South Florida for the better part of two decades. My name is on the truck, so the work has to be right, every time. That’s why we give you an honest number up front and honor it when the invoice comes.
DIY or Call Us?
The safe DIY checks: look at the bottom sweep, feel for drafts along the frame, and watch where the door catches as it closes. You can note all of that and describe it to us over the phone, and it helps us bring the right parts on the first trip. What you shouldn’t attempt yourself: removing a Therma-Tru hinge plate from the door slab without knowing the screw pattern (you can strip the insert), pulling the multi-point lock mechanism out of the door edge without releasing the faceplate properly (you can jam the bolt), or shimming a threshold on a door with a multi-point lock. Those lock mechanisms have internal tension and alignment points that go sideways fast if you’re not set up for them. This is the kind of repair where a wrong guess costs more than the service call. Call (727) 291-4678 and we’ll walk through what you’re seeing, give you a straight answer, and schedule from there. No trip charge inside the county, and estimates are free.
FAQs
Bottom sweeps and weatherstripping typically last 3 to 5 years in South Florida’s heat and humidity, sometimes less on west-facing doors. Hinges can go 15 years or more if the door is adjusted when it first starts to sag. Multi-point gearboxes usually fail somewhere between 8 and 12 years of daily use. Call (727) 291-4678 and we can check the specific wear on your door, free estimate included.
Sometimes. Worn hinges can often be re-shimmed and tightened, and a binding multi-point lock can occasionally be realigned instead of replaced. But a stripped gearbox or a cracked threshold cap is a replacement job. We’ll tell you which one you’re looking at before recommending work. Call (727) 291-4678 for an honest read on your door.
Most component replacements, including sweeps, thresholds, weatherstripping, and lock gearboxes, take 45 minutes to 2 hours once we’re on site. We bring the common parts with us, so most Little Gables jobs are one visit.
Yes. We keep sweeps, threshold caps, weatherstripping, hinges, and common multi-point lock gearboxes on our service vehicles.

Call (727) 291-4678 and we’ll confirm what we’ve got before we head over.
