AfterTherma-Tru Door Installation: The Plantation Owner’s Guide
Therma-Tru door installation in Plantation typically runs $340-$890 installed for a standard entry door swap, depending on whether we’re replacing the slab only or the full frame with rot repair. We stock Therma-Tru-compatible thresholds, weatherstripping, sweeps, hinges, and multipoint lock components on our trucks, so most jobs are done in one visit. The way most Plantation owners discover something failed is gradual: the door starts dragging on the threshold in August, or daylight shows through the corner where it never used to, or the deadbolt suddenly needs a shoulder to throw. By the time you call, it’s usually been binding for a season.
We’re an independent installer, not affiliated with Therma-Tru. That means we can tell you honestly when an OEM part is worth the wait and when a quality aftermarket equivalent does the same job for less.
Which Therma-Tru Models This Applies To
We install and service the full range: Fiber-Classic, Smooth-Star, Pulse, Tru-Defense, and the newer Benchmark line. The compatibility gotcha most Plantation homeowners miss is the hinge prep. Therma-Tru slabs ship with a proprietary hinge mortise pattern that does not always match a standard 4×4 butt hinge from the hardware aisle. If someone just screws a big-box hinge onto an unmatched prep, the door will sag within a year and the corner will start rubbing.
When we quote a Therma-Tru door installation in Plantation, we check three things first: the label on the hinge edge of the slab (it gives the series and manufacture date), the exact backset on the existing lock, and whether the frame is the original Therma-Tru jambs or a retrofit. Those details decide whether we reuse the slab, order a new one through a distributor in Fort Lauderdale, or rebuild the threshold. We always give you the OEM and aftermarket part options side by side on paper with the actual prices, not one mystery number on a napkin.
Signs Your Therma-Tru Door Installation Is Failing
- Corner drag on the latch side. This is the classic South Florida symptom. The slab expands just slightly in humidity, and if the install was set too tight or the hinges have worn, the top corner catches the frame. Cause: sagging hinge or an out-of-square frame that was never shimmed right.
- Daylight at the weatherstrip. If you can see a sliver of light around the door when it’s closed, the seal is not compressing. That’s lost AC, higher humidity inside, and a welcome mat for ants. Cause: compressed weatherstripping from age, or a frame that shifted.
- Deadbolt that fights you. When you have to lift the handle or push the door in to throw the bolt, the strike plate and the latch are no longer aligned. Cause: sag or foundation settle. In Plantation, both happen.
- Water staining at the bottom corners of the interior casing. That means moisture is getting past the threshold or the corner seals. Therma-Tru thresholds are composite and generally hold up, but the screw holes in the threshold cap can leak if the installer never sealed them.
- Condensation or hazing between the glass. On Therma-Tru doors with decorative glass or sidelites, a failed seal shows up as fog you cannot wipe off. That’s a sealed unit replacement, not a cleaning problem.
Replacement Cost & What’s Included
A standard Therma-Tru entry door slab replacement in Plantation runs $340-$560 installed for a clean swap with no frame damage. If the frame is rotted, out of square, or if we’re replacing the threshold and exterior brickmold, the job climbs to $640-$890. Sidelite replacements or decorative glass unit swaps land in the $600-$1,100 range depending on the glass pattern and whether it’s impact-rated. Every quote includes the part, labor, disposal of the old door, shims, sealant, and the lock reinstall, written line by line.
Our workmanship is guaranteed for 90 days under the Done Right Promise. If the door binds, if the seal fails, if it’s not right, we come back and make it right. No paperwork fight, no arguing. And we register both Therma-Tru warranty layers in writing before we pull out of the driveway. That’s the Keystone Standard, and it’s what we’ve done in South Florida since 2008.
DIY or Call Us?
You can check a few things safely yourself: look for daylight at the seal, check the hinge screws for tightness, and note whether the gap between the slab and frame is even all the way around. That information helps us quote faster. What you should not do is try to pull a Therma-Tru slab off its hinges and reset it on a Saturday. These doors are heavy, the multipoint lock mechanisms are unforgiving, and a slab that slips during removal can crack a tile floor or crush a foot. We’ve also seen more than one homeowner strip a hinge screw and then drill a new hole at a bad angle, which turns a $400 job into a frame replacement.
Dale Kessler learned doors the slow way: watching his father do finish carpentry and then spending two decades setting and finishing frames across Broward County. The rule he keeps on the whiteboard is the rule we work by: if the pane is not true, the job is not done.

FAQs
In Plantation’s humidity and rain, a well-installed Therma-Tru fiberglass entry door can last 25 to 30 years, but the weatherstripping, sweeps, and threshold need attention every 5 to 7 years. The slab itself holds up much better than wood, which is why the brand took over this market. Call (772) 577-2915 and we’ll tell you whether the door itself or just the seals are failing.
Yes, in most cases. Sagging hinges, worn sweeps, compressed weatherstrip, misaligned strike plates, and failed glass units are all repairable without replacing the slab. We only recommend full replacement when the slab is cracked, the frame is rotted beyond shimming, or the multipoint lock has failed in a way Therma-Tru no longer supports. Call (772) 577-2915 for an honest assessment, not a sales pitch.
A standard slab replacement takes 2 to 4 hours. A full frame replacement with threshold work can take 4 to 6 hours. We show up with the parts, the shims, and the sealant on the truck, so it’s usually done in one visit. Call (772) 577-2915 and we’ll give you a straight answer for your specific door.
We stock Therma-Tru-compatible thresholds, weatherstripping, sweeps, hinges, multipoint lock components, and common glass unit sizes on the truck. If your model needs a specialty part we don’t have, we order it through a local distributor and schedule the return visit the same week. Call (772) 577-2915 with your door’s hinge-edge label information and we’ll tell you exactly what’s available before we arrive.
We’re an authorized installer for more than a dozen lines, including PGT, CGI, and CWS. If you’re comparing impact-rated options, we’ll quote the manufacturers side by side on paper so you can see what you’re actually buying. Call (772) 577-2915 to schedule a free estimate.
