Therma-Tru Window Installation: The Fort Lauderdale Owner’s Guide

Therma-Tru window installation in Fort Lauderdale typically runs $350 to $900 per window when you already have the new unit in hand, and more if we’re pulling measurements, ordering the window, and doing a full tear-out and reset. We keep common Therma-Tru sash balances, pivot bars, tilt latches, and weatherstripping stocked on our trucks, so a basic hardware swap is usually a one-trip job. Most owners discover the problem the hard way: a window that won’t stay up, a top sash that flops inward when you tilt it to clean, or water staining the drywall after a heavy summer storm.

Which Therma-Tru Models This Applies To

We work on the full range of Therma-Tru residential window lines you’ll find in Fort Lauderdale homes, including the older vinyl series units and the newer impact-rated models that have become popular in eastern Broward County neighborhoods like Victoria Park and Rio Vista. Here’s the thing about Therma-Tru windows: the company built its reputation on doors, and their window hardware often crosses over with the parent line’s part numbering. The tilt-latch that fits one Therma-Tru window will sometimes also be listed under an older door-adjacent SKU, which confuses the heck out of homeowners trying to match parts online.

If you have the original window label, it’s usually on the top edge of the sash or the inside of the frame, and it’ll give you a date code plus a series designation. No label? We identify by measurement: the balance tube length, the sash weight rating, and the tilt-latch width. We’ve done enough of these in Fort Lauderdale that we can usually name the part from a photo and a tape measure. On the OEM-versus-aftermarket question: for Therma-Tru tilt latches and pivot bars we’re fine with quality aftermarket equivalents because the originals are commodity parts with the same profile. For balances, we prefer OEM or exact-spec replacement because the tension rating has to match the sash weight, and a mismatch either launches the sash too hard or lets it drop.

Signs Your Therma-Tru Window Installation Is Failing

• Sash drops or slams shut. The balance tube has lost tension, usually because the internal spring has fatigued. This is the most common Therma-Tru window failure we see in Fort Lauderdale, and the constant sun exposure on west-facing walls accelerates it.
• Window won’t tilt in for cleaning, or tilts too easily on its own. The tilt latches are either snapped off or so worn they no longer seat in the pivot bar. A window that un-tilts without being released is a real hazard if you’re reaching across a sink.
• Drafts or water staining at the bottom corners. The weatherstripping at the sill has compressed or the frame has shifted slightly out of square. In Fort Lauderdale, a failed weather seal isn’t just a comfort issue, it’s how salt air and humidity get into your wall cavity.
• Condensation between the glass panes. The insulated glass unit seal has failed. This isn’t a hardware fix, it’s a glass replacement, and it’s worth doing before the mineral haze becomes permanent etching on the interior glass surface.
• The sash sits crooked in the frame. Usually a broken pivot bar or a balance that has slipped out of its channel. Left alone, it will wear a groove into the jamb and turn a $50 part into a full frame repair.

Replacement Cost & What’s Included

Here are the numbers for Fort Lauderdale, laid out plainly:

• Tilt latch replacement (pair): $45 – $90 installed, parts included. We keep the common Therma-Tru profile on the truck.
• Pivot bar replacement (pair): $55 – $110 installed. Usually done at the same time as tilt latches since they wear together.
• Balance replacement (per window, both sides): $140 – $260 installed. The spread depends on whether the window is single-hung or double-hung and the sash weight rating.
• Full hardware rebuild (balances, pivots, latches, weatherstripping): $280 – $450 per window.
• Complete window replacement including new Therma-Tru unit: $650 – $1,700 per window for most Fort Lauderdale homes, with impact-rated glass on the upper end of that range.

Every one of those prices is a written line-item quote you’ll have in your hands before we touch the window. No change orders, no inflation after we open up the sash and “discover” a problem. The price we hand you is the price you pay. And every repair carries our written workmanship warranty, backed by the 365-Day Done Right Promise: if it’s not right, we make it right, no argument needed.

DIY or Call Us?

Window hardware isn’t in the same danger category as garage-door springs or electrical work, so I’m not going to tell you this is a life-threatening repair. What I will tell you is this: a window balance is under constant tension, and the older vinyl units in Fort Lauderdale get brittle after years of UV exposure. If you try to force a sash that’s fighting you, the plastic pivot bar snaps, and now you have a heavy glass unit swinging free in the opening. We’ve been called to more than a few homes where a well-intentioned owner took the sash out and couldn’t get it to seat back into the pivot channel. It’s hard to safely support a double-hung sash by yourself, and if it drops, you’re looking at broken glass and a trip to the ER.

What you can safely do: identify the model from the sticker, measure the visible part, and take clear photos. Then call us at (754) 354-3671. We’ll quote from your photos half the time, and if we need to see it in person, the estimate is free either way. Spencer Odell has spent the better part of two decades measuring and installing windows across Broward County, and he’d rather tell you honestly what the part costs than watch you wrestle a sash out of a second-story opening.
