Therma-Tru Impact Windows in Fountainebleau: What to Know First
Therma-Tru impact windows in Fountainebleau typically cost between $900 and $2,400 per opening installed, depending on the series and size, and most full-home replacements are completed within two to four weeks. We’re an independent Therma-Tru service provider, not a factory rep, which means we tell you the truth about what your current doors and windows need without a sales quota behind the conversation. If you own a Therma-Tru entry door with sidelites or a Therma-Tru fiberglass door paired with impact-rated glass and you’re wondering whether it’s holding up the way it should, this page is for you. Call (727) 620-6983 and you’ll get a real person, day or night.
How Therma-Tru Products Fail - and How We Fix Them
After 14 years working on Fountainebleau homes, we’ve seen the same few failure patterns repeat on Therma-Tru impact assemblies. Here’s what actually goes wrong, and what we do about it:
- Fiberglass skin delamination on Classic-Craft and Fiber-Classic doors. Fountainebleau’s humidity plus direct afternoon sun works on the adhesive layer between the fiberglass skin and the door’s core. You’ll see bubbling or a wavy reflection across the lower third of the door. The impact glass is usually still sound, so we re-bond the skin with a marine-grade adhesive rated for Miami-Dade’s moisture cycle rather than selling you a whole new door.
- Compression-set weatherstripping on Smooth-Star and Pulse series entry units. These doors shipped with a foam-core sweep that flattens permanently after a few Florida summers. You’ll feel hot air bleeding in around the bottom even though the door closes fine. We replace with a silicone bulb seal that keeps its shape at 140-degree threshold temperatures, which is what your south-facing Fountainebleau entry actually sees in August.
- Sidelite seal failure on Therma-Tru impact-rated entry systems. The sidelite frames on older Therma-Tru units used a butyl tape that dries out and pulls away from the glass. Water intrusion starts as a faint mineral streak on the interior sill. We pull the glazing stops, clean the channel, and re-set the glass with a UV-stable structural silicone, then water-test the assembly before we call it done.
- Thin-jamb screw pullout on Fiber-Classic hinge plates. We see this a lot in Fountainebleau because doors here get opened and closed constantly with kids, guests, and the general rhythm of family life. The factory jamb reinforcement wasn’t designed for 20 years of hard daily use. We install steel hinge-reinforcement plates behind the jamb so the door hangs true and seals evenly against the weatherstripping again.
- Threshold corrosion on Therma-Tru impact units with adjustable sills. The mill-finish aluminum thresholds on some older Therma-Tru lines pit and corrode after years of rain splash and irrigation overspray. Once the adjustable cap seizes, you can’t fine-tune the door seal anymore. We replace the sill with a thermally-broken composite threshold that won’t corrode and gives you back the adjustability.
Our Therma-Tru Impact Windows Process
Every Therma-Tru job in Fountainebleau follows the same sequence, no shortcuts:
- 1
Call and talk to a person. You call (727) 620-6983. We answer. We ask what you’re seeing and schedule a visit that works around your day.
- 2
On-site diagnostic. A uniformed, background-checked technician comes out, inspects the door or window, runs a water test if water intrusion is the concern, and takes measurements. You get a written, line-item estimate with the exact parts cost and labor broken out. No vague “miscellaneous” line items.
- 3
Parts decision, made with you. Where Therma-Tru OEM parts are available and warranty-sensitive, we use them. Where an OEM part has a known weak point, we tell you honestly and offer a quality aftermarket alternative that outlasts the factory piece. You decide with full information.
- 4
The work itself. We do the repair or replacement in a single visit whenever possible, protect your floors and entryway, and clean up after ourselves. Your house looks like we were never there, except the door finally works.
- 5
Testing before we leave. We cycle the door, check the seal with a light test, run the water test again if applicable, and walk you through what was done and why.
- 6
The Done Right Promise. If anything about the work isn’t done right, we come back and make it right. No fine print, no expiration, no arguing.
What Therma-Tru Impact Windows Costs in Fountainebleau
Here’s the honest pricing picture for Therma-Tru impact work in Fountainebleau:
- Weatherstripping and threshold replacement: $180 to $450 per door, depending on whether we’re doing the sweep alone or the full sill assembly.
- Sidelite re-seal on an existing Therma-Tru entry system: $350 to $700, including glass removal, channel prep, structural silicone, and water testing.
- Full Therma-Tru impact door replacement with sidelites: $3,800 to $7,500 installed, depending on size, series, and whether you’re matching existing hardware or upgrading.
- Complete Therma-Tru impact window package for a typical 2,000 sq ft Fountainebleau home: $18,000 to $42,000, with final price driven by window count, series selection, and structural opening requirements.
What moves the price most: the series you choose (Smooth-Star costs less than Classic-Craft), the number of openings, and whether any framing needs repair behind the existing unit. We’ll give you an exact number before any work starts, and that number doesn’t change unless you change the scope. Call (727) 620-6983 to schedule your free estimate.

FAQs
The Therma-Tru limited warranty covers manufacturing defects in the product itself, not installation workmanship. As an independent Therma-Tru service provider in Fountainebleau, we follow warranty-safe practices, use OEM parts where appropriate, and document everything so your original product warranty stays valid. If a factory defect is present, we’ll tell you exactly what to file and help you through the claim process.
Common wear items, like weatherstripping and threshold caps, we keep stocked and can replace same-week. For full door or window assemblies, Therma-Tru lead times run anywhere from two to six weeks depending on the series and customization. We’ll give you a realistic timeline before you commit to anything. Call (727) 620-6983 and we’ll check current availability for your specific model.
Repair wins when the glass is intact and the frame is structurally sound. If you have seal failure, hardware wear, or weatherstripping breakdown, repair typically runs 15 to 30 percent of replacement cost. Replacement makes sense when the frame is cracked, the impact glass itself is compromised, or you’re chasing recurring leaks that patches won’t resolve. In Fountainebleau, where hurricane season is a real annual event, we lean conservative: if there’s any question the unit won’t hold, we’ll tell you straight and recommend replacement.
Yes, Therma-Tru impact-rated products are tested and approved for high-velocity hurricane zones, including Miami-Dade County. However, the approval applies to the complete assembly as tested: glass, frame, hardware, and installation method. That’s why proper installation matters as much as the product rating. We install to the manufacturer’s spec and the Florida Building Code, pull permits where required, and make sure the job passes inspection the first time. If you’re unsure whether your existing Therma-Tru units are up to current code, call (727) 620-6983 and we’ll evaluate them for free.
