AfterTherma-Tru Door Installation: The Boca Raton Owner’s Guide
Therma-Tru door installation in Boca Raton typically runs $850 to $2,400 installed, depending on whether we’re swapping a slab into your existing frame or doing a full frame-out replacement. We carry Therma-Tru-compatible hinges, sweeps, weatherstripping, and threshold kits on our trucks, and we can usually have a standard replacement done within a few days of your call. The most common way owners find us is after a door that used to close clean starts dragging on the threshold or the sweep has torn away and daylight is showing under the door. South Florida humidity and daily sun exposure do a number on door seals, and Boca Raton homes near the Intracoastal get it worse because of the salt air.
Which Therma-Tru Models This Applies To
We work on the full Therma-Tru residential lineup, including Smooth-Star, Classic-Craft, Fiber-Classic, and Pulse series doors. The Smooth-Star is what we see most often in Boca Raton, especially in communities like Boca Del Mar and Loggers’ Run where the original construction dates back 20 to 30 years. Here’s the compatibility gotcha most people don’t know: Therma-Tru has used at least three different hinge prep patterns and two different sweep channel profiles across their product generations, so a hinge or sweep from a big-box shelf often doesn’t match what was originally installed. We identify the right part by the door’s serial label, which is usually on the hinge edge near the top, plus a quick measurement of the sweep channel and hinge spacing. For OEM versus aftermarket: Therma-Tru’s own weatherstripping and sweeps are worth the spend because their tolerances match the slab exactly. For hinges and screws, quality aftermarket is fine and often half the price.
Signs Your Therma-Tru Door Installation Is Failing
- Daylight visible under the door. The sweep has worn out or pulled loose from the channel. In Boca Raton, this is also where you’ll see water intrusion during afternoon thunderstorms, and it means your slab is now sitting against an unsealed gap.
- The door drags or binds when opening. Hinges have sagged, or the slab has absorbed moisture and shifted. South Florida’s humidity swings can swell a fiberglass door’s core enough to change the reveal by an eighth of an inch.
- You hear wind whistling around the jamb. The compression weatherstripping has flattened. After five to seven years of direct Florida sun, the Therma-Tru weatherstripping loses its rebound and can’t hold a seal anymore.
- A musty or rotten smell near the threshold. Water has been sitting in the threshold’s weep system. A threshold that doesn’t drain properly will rot the wood subfloor under it, and by the time you smell it, the repair gets bigger.
- The lock no longer lines up with the strike plate. This is usually hinge sag, not a lock problem. We see it often on older homes in East Boca where the original install used two hinges instead of three.
Replacement Cost & What’s Included
Most Therma-Tru door installation jobs in Boca Raton fall into one of two buckets. A slab swap, meaning we reuse your existing frame and replace the door panel plus hardware, lands between $850 and $1,450. A full frame-out, where the old frame comes out and a new pre-hung unit goes in, runs $1,500 to $2,400. What drives the range is simple: whether the frame is still square, what condition the threshold is in, and whether rot has spread into the rough opening. Every quote includes the parts, labor, haul-away of the old door, and our workmanship warranty. Ed Winslow’s view on this is straightforward: the price we quote is the price you pay, because nobody should find out the real number after the old door is already on the lawn.
DIY or Call Us?
There’s a short list of things worth checking yourself before you call: run a dollar bill along the weatherstripping to see where the seal is loose, check for loose hinge screws you can tighten with a no. 2 Phillips, and look for obvious damage to the sweep. That’s the safe list, and it ends there. What’s not safe is trying to pull a pre-hung Therma-Tru and change the rough opening yourself. You’re dealing with a 90-plus-pound slab, shimming, leveling, and waterproofing the sill pan so a Boca Raton downpour doesn’t end up inside your foyer. If it’s off by a quarter inch, the door will never lock right and the threshold will collect water. Given the kind of storms we get in Palm Beach County, this is the one place to be honest with yourself: call (561) 816-5648 and let us do it correctly.
FAQs
A properly installed Therma-Tru door slab will give you 20 to 30 years in Boca Raton, but the moving parts, sweeps, weatherstripping, and hinges, will need replacement every 5 to 8 years depending on sun exposure and how close you are to the salt air. Call (561) 816-5648 and we’ll tell you whether the slab or just the hardware needs swapping.
Yes, in most cases we can replace the failed component, a sweep, weatherstripping, hinges, or threshold, for a few hundred dollars instead of a full door replacement, and we stock the most common Therma-Tru parts on our trucks. If the frame is rotted or the slab is swollen beyond adjustment, replacement becomes the honest recommendation, and we’ll show you exactly why.
A slab swap usually takes 2 to 3 hours on site, and a full frame-out is a one-day job for most Boca Raton homes, barring any hidden rot in the rough opening that needs repair. We schedule the work in a single visit so you’re not sitting with a tarp over the opening overnight.
Our trucks carry Therma-Tru-compatible sweeps, weatherstripping, hinges, and multi-point lock hardware, and for less common finishes we can typically have the OEM part within a few days. If we can’t match what’s on the door, we’ll tell you before any work begins, because Ed Winslow doesn’t believe in finding surprises after we’ve started.
If your Therma-Tru door is dragging, leaking air, or just not closing the way it used to, call Winslow Windows & Doors at (561) 816-5648. We’ll get someone to your Boca Raton home, take a look, and give you a written quote before any work begins.
