Therma-Tru Window Replacement: The Lauderhill Owner’s Guide

Therma-Tru window replacement in Lauderhill typically runs $650 to $1,400 per window installed, depending on frame size, glass package, and whether we’re matching an existing finish. Most jobs are completed the same day we arrive. You usually discover the problem when condensation builds between the panes, the sash starts sticking in July’s humidity, or you can feel air moving around the frame even with the window locked.

We stock common Therma-Tru replacement parts on our trucks, and we quote the work in writing before we touch the opening. TruePane Windows & Doors is an independent service provider, not affiliated with Therma-Tru. That independence means we can match the part honestly, whether OEM or a tested aftermarket equivalent from a line we trust.

Key takeaways:

• Therma-Tru replacement parts are model-specific; a Tru-Defense sash will not fit a Slim-Line frame, and guessing costs more than measuring.
• Flush-fin and brickmould versions use different mounting hardware, even on the same nominal size.
• Most failures in Lauderhill come from seal degradation, not frame rot, and the fix is usually a sash or glass pack, not a full tear-out.
• We carry PGT, CGI, and CWS parts as well, so if your opening needs a different line, we can quote side by side.

Which Therma-Tru Models This Applies To

Therma-Tru’s window lines in South Florida break into a few families: the Slim-Line series, the Tru-Defense impact series, and a handful of builder-grade units that went into Lauderhill homes during the 2004-2008 construction wave. Each uses a different sash profile and balance system. If you open the sash and look at the bottom edge, you’ll usually find a foil label with the series name and a date code. No label? Measure the visible glass width and the sash thickness. Slim-Line sashes run thinner than Tru-Defense sashes, and mixing them means the window won’t seat, won’t seal, and will void whatever warranty remains.

The OEM-versus-aftermarket decision for Therma-Tru is straightforward. OEM sashes and glass packs come with the manufacturer’s warranty language and a known fit. Quality aftermarket equivalents from the major glazing suppliers in Broward County match the spec but may carry only the supplier’s warranty. We quote both on paper, with warranty durations stated, and let the homeowner choose. The Keystone Standard means whatever you pick gets registered in writing before the truck leaves your driveway.

One gotcha we see regularly in Lauderhill: houses built in the 1990s with original Therma-Tru windows often had custom millwork surrounds. A new sash will fit the frame, but the exterior trim may need recaulking while we’re there. We’ll tell you that before we start, not after.

Signs Your Therma-Tru Window Replacement Is Failing

• Condensation between the panes. The warm, wet air in Lauderhill works its way past a failed seal and fogs the inside of the insulated glass. This is the number one failure we see, and it usually appears within eight to twelve years on windows without a strong Low-E package.
• The sash drops or won’t stay open. Therma-Tru balance systems are spring-loaded. When the coil or block-and-tackle unit gives out, the sash drops like a garage door with a broken cable. You can prop it open, but the window is no longer functioning.
• Air you can feel around a locked window. If the weatherstripping is compressed flat or the frame has settled out of square, you’ll feel a draft in January and your AC leaks out all summer. The fix is usually a new weatherstrip set or a sash adjustment, but sometimes it’s a sign the frame itself has shifted.
• Water stains on the interior sill or drywall below. This is not a seal failure; it’s a drainage or flashing problem. In Lauderhill, afternoon thunderstorms find every gap in a window’s weep system. If water is getting behind the frame, we need to look before replacing the sash.
• Crank or lock hardware binds. Older Therma-Tru units used die-cast operators that corrode in coastal humidity. A replacement operator is often a ten-minute fix, and it’s a part we keep on the truck.

Replacement Cost & What’s Included

Here’s what Lauderhill homeowners can expect to pay for Therma-Tru window replacement parts installed:

• Single sash replacement (standard insulated glass): $350 to $600 installed
• Full window replacement (frame and sash, standard size): $800 to $1,400 installed
• Glass pack only (same sash, new sealed unit): $275 to $450 installed
• Balance or hardware replacement: $95 to $220 installed
• Tru-Defense impact-rated sash: $650 to $1,100 installed

The range depends on glass package, frame size, and whether custom sizing is required. Larger openings and impact-rated glass push toward the higher end. Every quote is a line-item price with labor separated from parts, so you see exactly what you’re paying for. We don’t hit you with surprise change orders, and the Done Right Promise covers the workmanship after we leave.

DIY or Call Us?

You can safely check a few things yourself: read the label on the sash to confirm the series, measure the visible glass, and note whether the condensation is between the panes or on the room side. That information helps us quote faster. What you shouldn’t do is pull the sash and start swapping balances. Therma-Tru balance springs are under tension, and a wrong move sends a steel coil flying. We’ve seen homeowners in Lauderhill lose a window and a thumb in the same afternoon.

If the window is cracked, fogged, or binding, the full diagnosis and replacement is a job for a glazier. We’ll match the part, set it square, and register the warranty before we leave. Call (850) 303-7739 and we’ll walk through what you’re seeing.
