Therma-Tru Impact Windows & Doors in West Park: What to Know First

We install and service Therma-Tru impact windows and doors in West Park as an independent provider, not a factory-authorized dealer. Most Therma-Tru jobs we handle run from a measured survey to completion in one to three weeks, depending on whether we’re sourcing OEM sash packs or working with in-stock impact-rated components. The price we write on the survey document is the price on the invoice - Haven Clause 1, no exceptions.

This page is for West Park homeowners who already have Therma-Tru products and need impact-rated replacement, repair, or upgrade work. That includes the Therma-Tru Pulse and Therma-Tru Classic-Craft lines we see in the area’s 1990s-to-2010s builds, plus newer Therma-Tru Fiber-Classic installations where the impact glazing has failed or the frame has shifted in South Florida’s wet-season expansion cycles.

How Therma-Tru Products Fail - and How We Fix Them

• Pulse series entry doors with delaminating impact glass. The Pulse line uses a steel-edge construction that conducts heat aggressively in West Park’s sun. After six to ten years, the thermal stress separates the impact interlayer from the lite, creating a fogged or “oily” appearance that doesn’t wipe off. We replace with OEM Therma-Tru impact glass packs where available, or specify a compatible impact-rated lite from our ES Windows or CWS supply chain when factory lead times stretch past three weeks. The frame stays; the glazing gets the correct sightline measurement so the door closes without binding.
• Classic-Craft fiberglass doors with frame racking after hurricane season. Classic-Craft’s fiberglass skin holds up, but the composite stiles can compress if the door was shimmed too tight against West Park’s common concrete-block openings. The result is a door that latches hard in June and rattles in January. We pull the unit, re-measure the rough opening with a laser level, and reinstall with composite shims sized to the actual gap - not the gap the installer hoped was there.
• Fiber-Classic sidelites with cracked impact glazing from pressure differential. Therma-Tru’s Fiber-Classic sidelites in West Park homes near Sunview Park often sit on the west face, baking all afternoon. The trapped air between impact lites expands, stressing the spacer seal until it weeps or cracks. We see this on units installed 2015-2019. Fix is a full sidelite sash replacement with updated warm-edge spacer technology, not a patch. We document the crack pattern with photos before the unit comes out - evidence for any warranty discussion.
• Multi-point locking hardware corrosion on coastal-exposed units. Therma-Tru’s standard multi-point hardware is brass-plated steel. In West Park, anything within two miles of the Intracoastal sees salt air that plates don’t survive. The lock tongue seizes, or the handle spins without engaging. We stock stainless-steel aftermarket multi-point sets from our ViewLux hardware supply that fit Therma-Tru prep without re-machining, or source factory hardware when the customer prefers OEM and can wait.
• Impact-rated patio door rollers flattened from track debris. Therma-Tru’s sliding patio door rollers use a nylon wheel that degrades faster than steel when West Park’s limestone grit gets into the track. The door gets heavy, then the frame torques, then the impact seal gaps. We pull the panel, clean the track to bare aluminum, and install steel-ball-bearing rollers with stainless housings. The door rolls lighter than new, and the impact seal seats evenly.

Our Therma-Tru Impact Windows & Doors Process

1. 1
   Call and schedule. A live person answers. We book a measured survey in West Park, usually within 48 hours. You keep the survey document.
2. 2
   On-site diagnosis. Our technician - license number provided before arrival - photographs the Therma-Tru unit, checks frame square with a laser, and notes the series, size, and failure mode. We test operation, seal continuity, and hardware function.
3. 3
   Parts decision. We quote OEM Therma-Tru components first. If factory lead time exceeds what the opening can tolerate, we present an equivalent impact-rated alternative from PGT, CGI, CWS, or ES Windows with full spec sheets. You choose; we document the choice.
4. 4
   Written price. The quote matches the survey document exactly. No line item gets added after signing. Haven Clause 1.
5. 5
   Installation and testing. We set the unit, check sightlines, verify impact seal engagement, cycle the hardware fifty times, and clean the work area.
6. 6
   Photo record and guarantee. You receive dated before-and-after photos and the 365-Day Done Right Promise, stamped under the Haven Standard. If it isn’t right, we make it right.

What Therma-Tru Impact Windows & Doors Costs in West Park

What moves the price: unit size, impact rating required (HVHZ vs. standard), OEM vs. aftermarket parts choice, and whether the rough opening needs reframing. West Park’s older concrete-block construction often has out-of-square openings that add two to four hours of prep.
