Therma-Tru Windows & Doors Nationwide

Therma-Tru Windows & Doors: The Fort Lauderdale Owner’s Guide

We stock and install Therma-Tru-compatible windows and doors across Fort Lauderdale, with typical replacement costs running $4,500-$15,000 for full window replacement and $8,000-$25,000 for impact-rated installations depending on series and opening count. Most Therma-Tru parts we carry on the truck, and we can usually match your model and get a written quote the same day you call. Most Fort Lauderdale homeowners discover a problem when they feel salt air blowing past a weatherstrip that won’t compress anymore, or when a door slab starts rubbing the jamb after our summer humidity swells the frame.

Which Therma-Tru Models This Applies To

Therma-Tru organizes their entry systems by door slab material and frame construction, and the part you need depends on which series is installed. Fiberglass Classic-Craft and Smooth-Star lines use different hinge mortise depths and weatherstrip profiles than the steel Builder’s Choice or fire-rated models. The label is usually on the hinge edge of the door slab, stamped with a date code and series abbreviation; if that’s painted over, measure the slab thickness (1-3/4″ for most exterior, 1-3/8″ for interior) and the hinge spacing center-to-center.

We source OEM Therma-Tru components where the spec matters, particularly for compression seals and multi-point locking hardware where third-party tolerances drift. For standard sweep seals and corner pads, we use quality aftermarket equivalents that meet the same durometer and UV-resistance ratings at a lower unit cost, and we list both options on the written quote. The gotcha in Fort Lauderdale is coastal-series versus inland-series hardware: the salt-air-rated multi-point locks use 316 stainless internals, and standard 304-grade replacements corrode inside 18 months within three miles of the Intracoastal. We check your ZIP against our salt-exposure map before ordering.

Signs Your Therma-Tru Windows & Doors Is Failing

• Visible daylight around the door perimeter when closed. The compression weatherstrip has lost its memory, usually from UV breakdown after 7-10 years of Florida exposure. The seal no longer rebounds to fill the gap between slab and jamb, and you’re paying to air-condition the outdoors.
• Door sticks or rubs seasonally, worse in August. The composite frame is absorbing moisture through a compromised finish or the sill pan weep holes are blocked with debris, causing the bottom of the frame to swell. In Fort Lauderdale’s 90-percent humidity, a blocked weep system can warp a fiberglass jamb enough to throw off the multi-point lock alignment.
• Multi-point lock bolts don’t retract or extend smoothly. The mechanism is gummed with salt residue, or the keeps (the strike plates) have shifted as the frame settled. Forcing the handle stresses the internal cams; we’ve replaced entire $400 lock bodies because a $12 keep adjustment was deferred too long.
• Condensation between glass panes on Therma-Tru sidelights or patio doors. The insulated glass unit seal has failed, releasing the argon fill and allowing moisture to wick in. In Fort Lauderdale, this accelerates once the desiccant inside the spacer saturates, typically 10-15 years from manufacture depending on exposure.
• Sill or threshold feels spongy or shows discoloration. Water is getting past the subsill or the end dams, often because caulk failed at the interface with the frame. On Therma-Tru’s adjustable sills, the composite cap can delaminate from the aluminum extrusion underneath, trapping moisture against the subfloor.

Replacement Cost & What’s Included

For Therma-Tru window and door work in Fort Lauderdale, our installed pricing runs $4,500-$15,000 for standard window replacement and $8,000-$25,000 for impact-rated window installation, with entry door replacements typically falling in the $3,000-$8,000 range depending on slab material and sidelight configuration. The spread is driven by four factors: whether the opening needs structural reframing, if we’re matching existing interior trim or replacing it, the hardware grade (standard versus coastal-rated stainless), and whether the job requires a permit and inspection.

Every quote we write breaks out parts, labor, and permit fees as separate line items. Under Clause 1 of the Haven Standard, that written price is fixed; no work proceeds on a change until the change order is signed. We pull permits where required by Broward County or your municipality, pass inspection, and back the installation with our 365-Day Done Right Promise. The documented photo record from our visit goes to you by text or email before we leave the site.

DIY or Call Us?

There’s a short list of checks any homeowner can make safely: clear weep holes with a pipe cleaner, verify the door closes against weatherstrip without slamming, and look for cracked corner pads at the sill ends. These take ten minutes and tell you whether the problem is maintenance or mechanical.

Where DIY goes wrong is door removal and multi-point lock service. A Therma-Tru fiberglass slab with sidelights can weigh 150 pounds, and the hinges are load-bearing in a way that interior doors aren’t. The multi-point lock mechanism stores spring tension; disassembly without supporting the bolts can launch hardware into your face or strip the internal cams. We don’t write step-by-step instructions for this because we’ve been called to fix the aftermath. If you’re seeing frame swelling, lock failure, or glass seal breach, call (754) 254-7676 and we’ll scope it in person, write the price, and schedule the work.
