Therma-Tru Windows & Doors in West Palm Beach, FL | Winslow Windows & Doors
We’re Winslow Windows & Doors, and we service Therma-Tru doors and West Palm Beach Window Installation across the area every week. We’re an independent Therma-Tru service provider, not a manufacturer affiliate, which means we answer to you, not a corporate territory map. What makes our Therma-Tru work different here is simple: we know what salt air, CBS settlement, and Palm Beach County wind codes do to these doors, and we fix them accordingly. Call (561) 782-7525 for a free estimate.

Why West Palm Beach Residents Choose Us for Therma-Tru Service
Therma-Tru builds a solid fiberglass door. But even a solid door has a hard life a few blocks from the Lake Worth Lagoon. We’ve pulled apart enough Therma-Tru slabs in El Cid and Flamingo Park to know exactly where they fail first, and we stock the genuine seals, weatherstripping, and lock bodies to fix them right. Ed Winslow grew up in El Cid, so he knows what the salt haze does to door hardware before the warranty card even fades. We keep a reference library of Therma-Tru sash profiles, hinge compatibility data, and finish specs because that’s what it takes to service these units correctly under Palm Beach County’s wind-load requirements and the city’s historic review process. Our Therma-Tru sales & service work is built on that local knowledge, not a call center script.
Common Therma-Tru Windows & Doors Problems We Solve in West Palm Beach
- Gel-coat cracking and spider webbing on fiberglass slabs. Within roughly 3,000 feet of the Intracoastal, the salt-haze and constant UV punish a Therma-Tru entry door’s finish. We see shallow spider webbing on Smooth-Star slabs and deeper fissures on Classic-Craft units that were never re-sealed after a few seasons.
- Multi-point lock misalignment on Tru-Defense doors. West Palm Beach’s older CBS homes settle. When the concrete block shifts, the door frame racks, and the multi-point locking rods bind. We realign the frame, synchronize the rods, and set the strike plates to two-point engagement so the lock actually locks.
- Compressed weatherstrip on double-door systems. The north-south afternoon sun beats on west-facing double doors in the 1950s-1970s ranch homes east of I-95. That heat flattens the compression weatherstrip, and you start feeling air and seeing water at the threshold.
- Hinge-side sag on heavy fiberglass slabs. Original hinge leaf screws lose their bite in the composite frame after a decade. The door drops, the reveal goes uneven, and the sweep stops sealing. We re-hang with stainless hinges and longer screws into the jamb, not just the frame skin.
- Sill pan corrosion on older Benchmark installations. Near Flagler Drive and the waterfront, the salt air eats at aluminum sill pans. We replace rotted sills with composite components and re-flash the opening so water sheds away from the CBS wall.
Therma-Tru Service in West Palm Beach: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Therma-Tru page. West Palm Beach sits outside Miami-Dade and Broward’s High-Velocity Hurricane Zone, so we’re not bound by HVHZ protocols. But Palm Beach County’s own wind-load requirements demand Florida Product Approval, with design wind speeds around 150 to 165 mph for Risk Category II structures. That means any permit-pulled replacement door has to carry impact-rated glazing or panels, period. At the same time, a homeowner in Flamingo Park or El Cid replacing a door has to clear two separate hurdles: the City of West Palm Beach Historic Preservation Board and the Palm Beach County Building Division. One review worries about sight-line dimensions and profile match to the original 1920s steel casement look. The other worries about wind pressure and impact rating. A standard contractor-grade vinyl door fails the first review before it’s even submitted. What this means for Therma-Tru owners: if you’re replacing a door in a historic district, bundle it with any window retrofit you’ve been putting off. Because pulling two separate permit cycles on one CBS house is the most expensive, slowest way to do the job. We’ve seen it add weeks. We’ve seen it double a homeowner’s paperwork. And we’ve learned to plan for it from the first site visit.
Therma-Tru Models & Products We Service in West Palm Beach
We work on Smooth-Star fiberglass entry doors, Classic-Craft fiberglass entry doors, Tru-Defense impact-rated door systems, and Benchmark door systems. When a door needs parts, we use genuine Therma-Tru seals, weatherstripping, lock bodies, and replacement sill components whenever they’re available. Aftermarket rubber profiles don’t have the same compression set, and in a salt-air zone, that difference shows up as a leak within two seasons. We keep common Therma-Tru weatherseal profiles and hinge packages in local stock for faster turnaround across West Palm Beach service area jobs. If your slab is structurally sound (no cracks through the fiberglass skin, a flat perimeter), we rebuild the frame, hinges, and weatherseal to get another five to ten years. If there are deep gel-coat fissures or the impact glazing was never installed properly, replacement is usually less money than repeated repairs.
Therma-Tru Service Pricing in West Palm Beach
Most Therma-Tru door repairs in West Palm Beach land between $150 and $600, depending on whether we’re replacing weatherstripping, realigning a multi-point lock, or re-hanging a sagging slab. Gel-coat surface repair on a fiberglass door runs $200 to $500. Full frame rebuilds with new hinges and threshold usually sit between $500 and $900. A complete Tru-Defense impact-rated entry door replacement, including the historic-review paperwork, starts around $1,800 and goes up based on slab style, glazing, and frame condition. What drives the price: salt-corrosion damage, CBS frame racking, and the dual-permit process in historic districts. What doesn’t drive it: bait-and-switch upsells. We give you a written, line-item quote before any work starts. Call (561) 782-7525 and we’ll come out, look at the door, and tell you exactly what it needs and what it costs. The estimate’s free.

FAQs - Therma-Tru Windows & Doors in West Palm Beach
No. Palm Beach County design wind speeds of 150 to 165 mph mean any replacement door must carry Florida Product Approval with impact-rated glazing or panels, so a permit is triggered regardless of the brand. West Palm Beach’s building division will not pass a non-impact door on a replacement job. Call (561) 782-7525 and we’ll confirm what your specific house requires before you spend a dollar.
Salt-air corrosion. Properties within about 3,000 feet of the mean high-water line along the Lake Worth Lagoon and the Atlantic sit in the Florida Building Code’s salt-air corrosion zone. The constant salt haze attacks door hardware, aluminum sill pans, and any exposed metal faster than inland air. We use corrosion-resistant hardware ratings on every waterfront replacement. If your door is near Flagler Drive, expect to replace hardware sooner than a house in, say, the western ranch neighborhoods. Call (561) 782-7525 for a free corrosion assessment.
Sometimes. A shallow surface crack in the gel coat can be repaired and re-finished for a few hundred dollars. But a crack that goes through the fiberglass skin means the slab has lost structural integrity, and in a wind-load zone, that’s not a door you want between you and a hurricane. We’ll tell you straight which situation you have. If it’s repairable, we’ll repair it and back it with our Done Right Promise. Call (561) 782-7525 for an honest assessment.
Yes. Historic homes in Flamingo Park and El Cid have masonry openings cut for narrower, period-correct profiles, and the historic board requires sight-line dimensions that match the original 1920s-1940s steel casement look. That means we often spec corrosion-resistant stainless hinges and compression weatherstrip that seats properly in shallower frame depths than what a new-construction door would use. A standard hinge package won’t sit right in a CBS opening that’s been there for 90 years. Call (561) 782-7525 and we’ll match the hardware to the opening, not the other way around.
It can, and in West Palm Beach’s historic districts it usually should. On a 1930s CBS house in El Cid, our crew pulled a permit-correct Tru-Defense entry door after the original slab cracked vertically through the lower gel coat and the multi-point locking rods stopped synchronizing. We replaced the full frame with a composite rot-proof jamb, hung the new slab with three stainless hinges instead of two, and set the strike plates to two-point engagement. Then we noticed the adjacent jalousie windows were leaking through the masonry openings during a pressure test, so we quoted a tandem Impact Windows - West Palm Beach insert retrofit while the historic board case was already open. Bundling the door and window work under one permit cycle saves weeks and avoids paying for two rounds of review. Call (561) 782-7525 to see if your house qualifies.
