Therma-Tru Window Installation: The Boca Raton Owner’s Guide

Therma-Tru window installation in Boca Raton typically runs $1,450 to $3,600 per opening, installed, with most single-unit replacements completed in one visit. That covers removal of the old unit, inspection and repair of the rough opening, new flashing, insulation, interior trim, and exterior re-sealing to match your home’s existing line. We stock Therma-Tru-compatible mounting hardware, balance assemblies, and sash components on our trucks, so a window that won’t stay up or won’t latch usually gets addressed the same day we arrive.

The way most Boca Raton homeowners discover their Therma-Tru window installation has failed is quiet: the window gets harder to slide, or condensation starts gathering between the panes, or the lock no longer lines up square. You may have lived with it for a season thinking it’s just old age. Usually it’s a specific part: a worn balance, a swollen seal, or a hinge that’s drifted out of alignment from years of salt air and summer humidity.

Which Therma-Tru Models This Applies To

We service and install components for the full range of Therma-Tru vinyl and fiberglass window lines found in Boca Raton homes: the Casement, Double-Hung, Single-Hung, Sliding, Awning, and Picture series. Within those lines, Therma-Tru uses model-specific balance springs, keepers, and corner gaskets, and a hardware set from a Double-Hung won’t always seat correctly in a Slider even if the screws line up. That’s the compatibility gotcha. When we arrive, we read the corner label on the sash and the glass etches on the frame, then match parts by series, generation, and date code rather than guessing by look.

For owners, the meaningful choice is OEM Therma-Tru versus a quality aftermarket equivalent. The truth is both can work well when the part is matched correctly. What matters in Boca Raton’s climate is that gaskets and seals are rated for high UV exposure and repeated wet-dry cycles. Cheaper generic foam compression seals break down in three to five years here. A properly matched Therma-Tru or equivalent EPDM gasket can go twelve to fifteen. We quote both sides on paper so you can see exactly what you’re buying before any work starts.

One more note: TruePane Windows & Doors is an independent service provider, not a Therma-Tru dealer or franchise. We stock Therma-Tru-compatible parts because this brand shows up in a lot of Boca Raton homes built in the 1990s and 2000s, alongside PGT, CGI, and CWS.

Signs Your Therma-Tru Window Installation Is Failing

• The sash won’t stay open. The balance spring or block-and-tackle assembly has lost tension or snapped. In south Florida’s humidity, the metal components inside the balance can corrode faster than the window itself wears out.
• Condensation you can’t wipe away. Moisture between the glass panes means the insulated glass unit’s seal has failed. Once that seal lets go, the argon gas escapes and the window loses its thermal rating permanently.
• The lock or latch won’t engage. Usually the frame has shifted, or the keeper on the opposing sash has worn down. A window that won’t lock in Boca Raton is also a security issue worth addressing promptly, not just a comfort problem.
• Water stains on the interior sill or wall below. Failed flashing or a broken exterior seal is letting rain drive in around the frame. Over time this rots the rough opening behind the trim, and the repair bill climbs with the damage.
• The window binds or scrapes when you open it. The sash has gone out of square, often because the frame has settled or the hinge track has accumulated grit and corrosion. Forcing the window open makes the problem worse.

Replacement Cost & What’s Included

For a Therma-Tru window installation in Boca Raton, most single-window replacements land between $1,450 and $3,600 installed, depending on the window’s size, the series, and what we find when the old unit comes out. A basic single-hung in a standard 36 by 48 opening might run close to the lower end. A large casement or a window with rotted framing work runs higher. What you get for that price is specific: removal and disposal of the old unit, inspection and repair of the framing beneath, new flashing and insulation, the correct Therma-Tru-compatible hardware and balance set, interior trim restored, and full exterior caulking. No surprise line items, no change order halfway through.

Every Therma-Tru window installation we do in Boca Raton is covered by our Done Right Promise. If the window isn’t square, doesn’t seal, or doesn’t operate correctly within 90 days of the install, we make it right, no paperwork fight. We also register both warranty layers, manufacturer’s and our workmanship, in writing before the truck leaves your driveway.

DIY or Call Us?

There are a few things a homeowner can safely check. You can clean the hinge tracks, clear drain channels of debris, and verify whether the sash sits level in the frame. You can check the exterior caulking around the frame for cracks or separation. That’s inspection, and it’s useful.

What homeowners shouldn’t do is attempt a full window replacement themselves, especially on second-story openings or any window being upgraded to impact-rated glass. A window that comes loose during a hurricane isn’t a problem you want to discover at 4 a.m. in September. Loading a new balance assembly into a Therma-Tru frame under tension can cause injury if done wrong, and a poor installation voids the manufacturer warranty and leaves your interior open to mold from water intrusion. The work isn’t just swapping glass. It’s squaring the frame, flashing the opening, and sealing so the window holds through a Boca Raton storm season. That’s our trade, and we stand behind it.
