Why Fort Lauderdale Homeowners Choose Therma-Tru Windows & Doors
Winslow Windows & Doors provides independent Therma Tru in Fort Lauderdale repair, service, and installation, and we’re the crew homeowners call when salt air and hurricane season find the weak points in their entry systems. Therma-Tru builds a solid fiberglass door, but nothing holds up forever against Broward County’s marine environment, and we’ve spent years learning exactly where these units fail and how to fix them right. We’re not a Therma-Tru authorized dealer, and you should know that upfront. But what we bring is more useful than a manufacturer’s stamp: hands-on experience rebuilding Therma-Tru entry doors and replacement windows across Fort Lauderdale’s canal-front streets, salt-sprayed corners, and HVHZ wind zones. Ed Winslow’s name is on the door, literally, and every Therma-Tru job we take on gets the same standard: done right, or we come back. Call (904) 913-5886 for a free estimate.
Why Trust Winslow Windows & Doors for Your Therma-Tru Windows & Doors?
Our technicians have rebuilt Therma-Tru entry systems and replacement windows across Fort Lauderdale’s salt-air, hurricane-wind environment, and we independently reverse-engineer their frame and glass packages for real-world performance. That means when we show up to a Classic-Craft door that’s binding in the frame, we don’t just look at the hinges. We check the slab for moisture absorption, measure the threshold pitch, inspect the weatherstripping compression, and look for the salt corrosion that’s quietly eating the hardware from the inside. Born and raised in Miami, Ed Winslow spent years measuring, fitting, and standing behind windows and doors along Fort Lauderdale’s Las Olas corridor before putting his own name on a truck. That hands-on background means our crew treats Therma-Tru products the way a mechanic treats a specific engine: we know the quirks, the common failures, and the repair that actually lasts. We use genuine Therma-Tru components where they matter most, and we won’t sell you a full replacement when a $40 weatherseal kit solves the problem. My name’s on the door, literally. That means it gets done right.
Common Therma-Tru Windows & Doors Problems We Fix in Fort Lauderdale
- Warped or delaminating fiberglass door slabs on east-facing exposures. Therma-Tru’s Classic-Craft and Fiber-Classic lines hold up well in most climates, but Fort Lauderdale’s combination of relentless UV and salt-laden Atlantic air is brutal on east-facing entries. We regularly see slabs that have begun to delaminate at the bottom corners or warp enough to bind against the frame. The fix depends on how far the damage has gone, but in many cases a replacement slab with upgraded weathersealing and marine-grade hardware solves it without replacing the entire frame.
- Failed door bottom sweeps and weatherstripping letting wind-driven rain into entry thresholds. This is the single most common Therma-Tru complaint we hear in Fort Lauderdale, especially in neighborhoods like Coral Ridge and Lake Ridge where canal-front homes take direct wind off the water. The original sweeps on older Therma-Tru doors weren’t spec’d for sustained horizontal rain, and once they compress or tear, water pushes right under the slab. We replace them with high-compression sweeps and adjust the threshold so the next storm doesn’t leave a puddle on your entry tile.
- Fogged insulated glass units in Therma-Tru sidelites due to broken seals. If you’ve got a Therma-Tru entry door with sidelites and those sidelites have gone foggy, the seal on the insulated glass unit has failed. Fort Lauderdale’s humidity and temperature swings accelerate seal breakdown, especially on south-facing exposures. We can replace just the glass unit in most Therma-Tru sidelites without replacing the door itself, and we’ll be honest with you about whether a sash rebuild is worth the money or if it’s time to look at a full replacement.
- Loose or corroded hinge and threshold screws on older Classic-Craft units. Therma-Tru’s Classic-Craft line has been around for decades, and plenty of Fort Lauderdale homes still have the original installations. The fiberglass slab holds up, but the hardware doesn’t always. We see hinge screws that have wallowed out their holes, thresholds with stripped fasteners, and stainless screws that turned out to be anything but. We re-drill, reinforce, and upgrade to true marine-grade stainless so the door swings true and seals tight.
- Therma-Tru Pulse door bottom and seal failures from constant use. The Pulse line is Therma-Tru’s newer, more contemporary series, and it’s popular in Fort Lauderdale’s updated mid-century homes. The most common issue we see is the adjustable door bottom seal wearing out faster than expected, especially on doors that get heavy daily use in the humid season. We stock replacement seals and adjust the sweep height so the door clears the floor and still seals against driving rain.
Therma-Tru Parts & Our Repair-vs-Replace Approach
We use genuine Therma-Tru components where they matter most: door slabs, glazing beads, and threshold caps. Those are the parts that affect structural integrity, security, and water intrusion. For hardware like hinges, weatherstripping, and screws, we’ll substitute quality aftermarket parts when OEM is discontinued or weeks out, because a family with a sticking front door in Sailboat Bend can’t wait three weeks for a hinge shipment. We’re honest about the line between repair and replacement. If the slab or frame shows structural rot, or if a glass seal failure has gone beyond a simple sash rebuild, we’ll tell you straight that replacement makes more sense than sinking money into a losing repair. You won’t get a sales pitch, you’ll get a recommendation based on what’s actually in front of us. Call (904) 913-5886 for an honest assessment.
Our Therma-Tru Service Process - Step by Step
- 1
Diagnosis. We inspect the full assembly: slab, frame, hinges, threshold, weatherstripping, and any glazing. For Therma-Tru units specifically, we check the slab’s moisture content, look for delamination starting at the bottom corners, and test the compression of every seal. We tell you exactly what’s wrong, what caused it, and what it’ll take to fix it.
- 2
Repair or install. We use genuine Therma-Tru components for slabs, glazing beads, and threshold caps, and we upgrade hardware to stainless when the original materials are what failed in the first place. Every repair is done to hold up against Fort Lauderdale’s salt air and hurricane-wind rain, not just to pass a visual inspection.
- 3
Test. We simulate water intrusion at the threshold, check the slab’s swing and seal compression, and run the door through full open-close cycles before we call the job done. On impact-rated Therma-Tru installations, we verify the unit meets HVHZ requirements before final sign-off.
- 4
Warranty. Every Therma-Tru service we perform in Fort Lauderdale falls under the 36500-Day Done Right Promise. If it’s not done right, we make it right. That’s not a marketing line, it’s a century-long standard that Ed Winslow put in writing when he founded this company in 2011.
Therma-Tru Products We Service & Install in Fort Lauderdale
We service and install the full range of current and legacy Therma-Tru product lines, including Classic-Craft, Fiber-Classic, Smooth-Star, and Pulse. That covers entry doors, front doors with sidelites, replacement windows, and the hardware and weathersealing systems that keep them functioning in Fort Lauderdale’s marine climate. We keep common Therma-Tru weatherseal kits, door bottom sweeps, adjustable thresholds, and stainless hardware in local stock so we can complete most repairs without waiting on a manufacturer shipment. For full-frame replacements and impact-rated installations, we work directly with Florida Product Approval and HVHZ-compliant Therma-Tru units. We specialize in entry doors, Impact Windows, and full frame replacement.
We Also Service These Brands
Therma-Tru is a big part of what we do, but it’s not all we do. We’re authorized installers for PGT, CGI, CWS, and ES Windows as well, which means when a Fort Lauderdale home needs a mix of impact windows and entry doors, we can handle the whole job without farming anything out. That multi-brand experience also makes us better at Therma-Tru work, because we understand how different manufacturers’ systems compare and where Therma-Tru’s strengths and weaknesses actually sit.
FAQs - Therma-Tru Windows & Doors Service in Fort Lauderdale
Yes, we can replace just the Therma-Tru door slab and keep your existing frame and hardware in most cases. The key is confirming the frame is still square, the hinge locations match the new slab’s preps, and the original hardware hasn’t corroded past the point of reliable function. In Fort Lauderdale’s salt-air environment, we often find the slab is fine but the hinges and threshold screws have started to pit, and that’s the time to upgrade to stainless while the slab is off. Call (904) 913-5886 for an exact quote on a slab replacement.
Most Therma-Tru entry doors don’t actually swell from moisture the way a wood door would, so when a Therma-Tru slab starts sticking during Fort Lauderdale’s humid months, the real cause is usually the frame shifting or the threshold moving as the concrete slab beneath it expands and contracts with temperature and moisture. The slab itself is fiberglass, which doesn’t absorb water, but the frame installation might have settled, or the hinge screws may have loosened, or the threshold was set too high originally and the humid-season slab movement makes it bind. We’ll diagnose the actual cause and fix it rather than just shaving the door, which is what a lot of handymen will do and then the door leaks water at the bottom.
We handle fogged glass in Therma-Tru sidelites and transoms regularly, and in most cases we can replace just the insulated glass unit without replacing the entire door assembly. Fogging means the seal on the glass unit has failed and moisture has penetrated between the panes. We’ll pull the old glazing bead, order the exact-size replacement unit rated for your Therma-Tru frame, and install it with new glazing tape and a weatherseal check on the entire opening. If the seal failure has gone on long enough that the frame or sash is compromised, we’ll tell you that too.
Older Therma-Tru Classic-Craft doors in Fort Lauderdale are often worth repairing after hurricane damage, because the fiberglass slab itself is usually the strongest part of the assembly. What fails is the hardware, the weathersealing, the threshold, and sometimes the frame, and all of those are replaceable. A Classic-Craft slab that’s structurally intact can outlast a replacement that costs four times as much, and we’ll give you an honest recommendation on which side of that line your door falls. Call (904) 913-5886 and we’ll assess it in person.
For a Therma-Tru front door near the beach in Fort Lauderdale, we recommend a full compression weatherseal upgrade with a high-density Q-Lon or similar closed-cell foam seal on the jamb, a reinforced door bottom sweep rated for driving rain, and a marine-grade stainless threshold cap with proper drainage channels. Standard Therma-Tru weathersealing works fine inland, but canal-front and beach-facing entries need seals that maintain compression under sustained wind loads and resist salt degradation. We stock these upgraded seals locally and can install them in a single visit.
Therma-Tru windows and doors service in Fort Lauderdale varies by the scope of work, but here’s what to expect for common jobs: weatherseal and sweep replacement, $40 to $180; hinge and hardware rebuild, $150 to $400; insulated glass replacement in a sidelite, $250 to $650 per unit; door slab replacement, $800 to $2,400 depending on the model and size; full-frame entry door replacement with HVHZ-rated Therma-Tru product, $3,500 to $8,000. These are the ranges we’ve quoted across Fort Lauderdale’s neighborhoods from Coral Ridge to Croissant Park. Call (904) 913-5886 for a free estimate and we’ll give you an exact number before any work begins.
