AfterTherma-Tru Impact Windows in Fort Lauderdale: What to Know First
Therma-Tru impact windows in Fort Lauderdale run $1,850 to $4,200 per opening installed, depending on the series and size. TruePane Windows & Doors installs and services Therma-Tru impact-rated units as an independent provider, with most single-opening replacements completed in one visit. We quote line by line, register both warranty layers in writing, and stand behind the work for 90 days with no fine print.
This page is for homeowners who already own Therma-Tru products and are weighing repair against replacement, or who have heard the brand name and want straight answers about whether it holds up in our salt air. Call (954) 280-4413 and Dale or one of our senior techs will walk you through it.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a lot of exterior door systems, and in South Florida their impact-rated window and door lines end up on homes that were built or renovated after the 2001 Florida Building Code changes. The brand’s failure patterns in Fort Lauderdale are specific, and they are not the same as what we see on PGT or CGI units. Here is what actually goes wrong with Therma-Tru impact products in our climate, and what we do about it:
- Swing door sill rot on Thermal-Tru fiberglass door systems (Tru-Defense and Classic-Craft lines). The fiberglass skins hold up, but the sill caps and the wood core beneath them take on water from wind-driven rain off the Atlantic. We replace the sill with a composite cap, reset the door on shims so it drains outward, and re-seal the threshold. If the core is gone, we quote a full door replacement rather than patch a frame that will fail again.
- Multi-point lock binding on Therma-Tru sliding patio doors. In salty, humid air the lock’s sliding tongue and the keepers corrode faster than the stainless parts Therma-Tru specs on northern jobs. Owners tell us the door is “stuck” when the real issue is a corroded lock mechanism fighting the track. We pull the hardware, clean or replace the slides, and re-time the multi-point so the handle throws with one motion.
- Weatherstripping compression set on hinged Therma-Tru impact doors. Foam and bulb seals compress permanently after eight to ten Fort Lauderdale summers, then the door rattles and drafts. We re-gasket with EPDM bulb stock cut to the Therma-Tru profile, adjust the strike plates, and test with a flashlight and a dollar-bill pull so the owner can see the seal before we leave.
- Failed glazing tape on impact-rated insert windows. Therma-Tru’s impact inserts rely on structural silicone or butyl tape between the frame and glass. After years of 90-degree heat and UV, the tape can shear, leaving a hairline path for water to reach the weep system. We pull the sash, cut out the old tape, re-bed the glass on fresh structural adhesive, and reset the weep covers so the window drains the way it was designed to.
- Hinge sag on out-swing impact doors (Therma-Tru’s Smooth-Star and Pulse lines). The weight of an impact-rated slab tests any hinge in salt air. We see the top hinge pulling screws and the slab dropping so the lock no longer aligns. The fix is a steel-shimmed hinge pack, longer stainless screws into the framing, and re-hanging the slab so the reveal is even top to bottom before we touch the lock.
Our Therma-Tru Impact Windows Process
Here is how a Therma-Tru job goes at TruePane, from the first call to the last sweep of the driveway:
- 1
You call, a person answers. You talk to a live person at (954) 280-4413, day or night. We ask what the window or door is doing, when it started, and whether you know the series name or have the original paperwork.
- 2
We measure every opening twice. A background-checked, uniformed tech comes out and measures both diagonals, the reveal, and the rough opening. On a Therma-Tru job we also check the sill slope and the existing weep system, because those are where repairs fail if they get skipped.
- 3
We quote side by side on paper. If replacement is the right call, we show you OEM Therma-Tru lines next to PGT, CGI, or CWS equivalents, with numbers for each. You see exactly what you are paying and why. No single-number bid with a shrug.
- 4
We do the work in one visit when it is a repair or single-opening swap. Parts are pulled and staged before the truck is loaded. The opening is prepped, the new or rebuilt unit set, shimmed, and fastened per the manufacturer’s published installation method so the warranty stays intact.
- 5
We test before we clean up. Water test at the sill, lock cycle, seal check, and a walk-around with you so you see the result. Both warranty layers are registered in writing before the truck leaves your driveway.
- 6
If anything is not right, we come back. That is the Done Right Promise. No paperwork fight, no argument. If the pane is not true, the job is not done.
What Therma-Tru Impact Windows Costs in Fort Lauderdale
Straight numbers, because you asked. Single-hung Therma-Tru impact inserts in standard sizes run $1,850 to $2,600 per opening installed. Larger casement or picture units go $2,400 to $3,400. Therma-Tru impact swing doors start around $3,200 and can reach $4,200 or more for a 36-inch slab with multi-point hardware and a composite sill. Repairs are a different line item: re-gasketing a door runs $180 to $300, a lock rebuild with parts runs $220 to $450, and a full sill replacement on a fiberglass door runs $450 to $900 depending on the core damage.
What moves the price is the opening size, whether the frame is square enough to salvage, and whether the unit is still under a transferable warranty that dictates OEM-only parts. Call (954) 280-4413 for a line-item quote. It costs nothing and takes about twenty minutes.
Why Fort Lauderdale Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We have been serving Fort Lauderdale homeowners since 2008, and Dale Kessler founded TruePane in 2008 because he got tired of seeing out-of-true installs and warranty paperwork that protected nobody. Our techs are background-checked and uniformed, and they know Therma-Tru products well enough to tell you when an OEM part is worth the wait and when a quality aftermarket part does the same job for less money. We are also an authorized installer for PGT, CGI, CWS, and ES Windows, so if a full replacement makes more sense than patching a tired Therma-Tru unit, we quote those side by side on paper and let you decide. The Keystone Standard applies to every job: both warranty layers registered in writing, durations stated, before we leave the driveway. If it is not done right, we make it right within 90 days. No arguing. We live here, and we plan to be here in thirty years.
FAQs
No, not when the work is done according to Therma-Tru’s published installation method and with parts that meet their specs. That is why we pull the manufacturer’s current install document before we touch a unit and why we register both warranty layers in writing. Call (954) 280-4413 and we will tell you exactly what your warranty covers before any work is quoted.
In Fort Lauderdale, it is usually both, but the lock is where owners notice it first. Corrosion on the multi-point hardware and hinge sag work together, and fixing one without the other just moves the problem a few months down the road. We check both on every service call, because that is how you keep the door working for another decade instead of another season.
Most Therma-Tru impact window problems we see in Fort Lauderdale are repairable: failed glazing tape, worn weatherstripping, misaligned sashes, and clogged weep systems are all fixable in one visit. The cases that call for replacement are broken insulated glass units, severely corroded frames, or frames that were installed out of square. Get a free estimate at (954) 280-4413 before you assume the worst.
We answer the phone around the clock, and we schedule most Therma-Tru repair calls within one to three business days depending on the part needed. If your door is stuck open or will not lock, tell the person on the phone exactly that and we will get someone out fast. Call (954) 280-4413.
We do both. We install new Therma-Tru impact windows and doors, and we also quote PGT, CGI, CWS, and ES Windows side by side so you can compare numbers on paper. Call (954) 280-4413 and we will measure, price, and register everything in writing before any work starts.
