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

We install and service Therma-Tru impact windows and doors in Sunrise as an independent provider, not an authorized dealer. Most Therma-Tru jobs we handle run from $340 for a single-hung sash replacement to $4,200 for a full impact-rated door and frame unit, and we put that written price in your hands before any work starts. Our measured survey and your quote are the same document - Haven Clause 1 - so the number you see is the number on the invoice.

This page is for Sunrise homeowners who already have Therma-Tru products and need impact-rated repair, replacement, or upgrade work done correctly the first time. If you’re in the Inverrary area, Sawgrass Estates, or west of the Sawgrass Expressway and your Therma-Tru units need attention, call (754) 254-5294 to schedule your free estimate.

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

• Impact sash corner separation on Classic-Craft and Fiber-Classic series. The pultruded fiberglass frame expands at a different rate than the vinyl glazing bead in Broward’s humidity cycles. After three to four years, the bead loosens and the laminated glass slips in the rabbet. We remove the sash, re-bed with structural silicone rated for the full wind-load span, and replace the bead with OEM-spec retainers rather than generic snap-in.
• Threshold rot beneath Smooth-Star impact-rated entry systems. The composite threshold drains through two small weep slots that clog with Sunrise’s sandy soil and roof runoff. Water pools, the composite delaminates, and the sill plate beneath begins to decay. We pull the threshold, inspect the rough-opening subfloor with a moisture meter, install a sloped pan flashing with oversized drainage, and reset the door to the measured survey spec.
• Multi-point lock misalignment on DuraProtect impact door systems. The three-point deadbolt set drifts when the hinge-side jamb settles in the sandy fill common to Sunrise’s western developments. The top bolt misses the striker by 3/16″ and the door won’t seal against the weatherstrip. We don’t shim and hope; we pull the casing, re-anchor the jamb with structural screws to the king stud, and re-machine the striker locations to the factory template.
• Laminated glass delamination on older Pulse series units. The PVB interlayer breaks down at the edges first, visible as a milky haze that starts at the sightline and creeps inward. This is not cosmetic - it’s a failure of the impact membrane. We source replacement IGUs from a certified fabricator with the same missile-impact certification as the original, document the rating stamp, and register the warranty transfer with the glass supplier.
• Operator arm fatigue on Therma-Tru casement impact units. The scissor mechanism sees constant load from positive pressure in our easterly wind patterns. The brass bushing wears oval, the arm chatters, and the sash won’t hold its designed compression against the frame. We replace with the OEM operator rather than a universal fit - the mounting hole pattern and torque spec are proprietary - and test the closing force with a spring gauge before we leave.

Our Therma-Tru Impact Windows & Doors Process

1. 1
   Measured survey. We document every opening with a laser measure and record frame squareness, rough-opening condition, and existing fastener pattern. You keep this document.
2. 2
   Diagnostics with the unit in place. We run the sash, test the lock engagement, check the glazing bed with a feeler gauge, and photograph any delamination or seal failure. No guesswork.
3. 3
   Parts decision. OEM Therma-Tru components when available and warranty-appropriate; quality aftermarket when the OEM part is obsolete or when an upgraded component (stainless hinge pin, improved weatherstrip pile) outperforms the original. We explain the choice in writing.
4. 4
   Repair or replacement. Work proceeds from the written scope only. If we find concealed damage - subfloor rot, king-stud compromise - we stop, photograph, and present a revised scope before continuing.
5. 5
   Performance test. Every impact-rated unit gets a closed-door/window pressure check, lock-set cycling, and sightline alignment verification against the measured survey.
6. 6
   Documentation handoff. Photo record, updated measured survey, written invoice matching the quote, and the 365-Day Done Right Promise stamped and dated.

What Therma-Tru Impact Windows & Doors Costs in Sunrise

What moves the price: unit size, whether the rough opening needs reframing, accessibility (second-story installs in Sunrise’s gated communities often require interior carry), and whether we encounter concealed water damage once the unit is out. We price for what we find, not what we hope. Call (754) 254-5294 for your exact number - estimates are free, and we offer a free second opinion on any written estimate you’ve already received.

Why Sunrise Homeowners Call Sightline Windows & Doors Sunrise for Therma-Tru Work

We’ve installed and serviced 18,000+ openings since 2012, and a measurable share of those have been Therma-Tru units in Sunrise neighborhoods from Inverrary to Sawgrass. Sonia Raman tracks every callback by manufacturer and failure mode - it’s how we know that Pulse series delamination spikes in year six, or that DuraProtect lock drift correlates to specific soil conditions west of Nob Hill Road.

Our technicians are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. The price you get is the price you pay - Haven Clause 1. And if something’s not right, we make it right for 365 days - written into the Haven Standard, not offered as a courtesy.

We also carry PGT, CGI, CWS, and ES Windows lines, so if your Therma-Tru unit is obsolete or if a different manufacturer better matches your performance requirement, we can specify across eight product lines without steering you toward what’s in our warehouse.
