Therma-Tru Windows & Doors in Palm Beach, FL | Winslow Windows & Doors
We’re Winslow Windows & Doors, and we’ve been servicing Therma-Tru entry systems and windows across Palm Beach since 2011. We’re an independent service provider, not a factory shop, which means we fix what’s actually wrong instead of selling you a replacement you don’t need. What makes our Therma-Tru work different here: we’ve spent years field-servicing these doors in the island’s salt air, where hinges corrode twice as fast as anywhere on the mainland. Call (561) 782-7525 any hour and you’ll get a real person, not a phone tree.

Why Palm Beach Residents Choose Us for Therma-Tru Service
We know Therma-Tru doors the way a Palm Beach homeowner knows to close the shutters before a named storm. Ed Winslow grew up in El Cid, the historic neighborhood just west of the Intracoastal, where he watched salt air eat window hardware season after season. That’s not a sales pitch. It’s why we carry OEM Therma-Tru sweeps, corner seals, and sill caps on our trucks instead of waiting on a distributor three days out.
We’re the locally owned alternative to the national companies that hand you a ticket number and a four-week window. Every tech who shows up at your door is background-checked and in uniform. Calls are answered by a live person 24/7. And our Therma-Tru sales & service work carries the Done Right Promise: if it’s not done right, we come back and make it right. No fine print, no warranty card that evaporates after the check clears. Ed puts his name on every job we do.
Common Therma-Tru Windows & Doors Problems We Solve in Palm Beach
- Fiberglass skin delamination at the bottom rail. Salt-laden moisture wicks up into the door slab and causes visible bubbling that homeowners mistake for a finish defect. It’s not the paint failing. It’s moisture intrusion from the constant dual-salt-air exposure this island gets from both the Atlantic and the Intracoastal. We repair or replace the slab depending on severity.
- Galvanic corrosion of the adjustable aluminum sill cap. In Palm Beach’s salt air, the sill cap starts pitting within seven to ten years and eventually seizes, losing the weep function that channels water away from your threshold. You’ll notice water pooling at the door base after summer downpours. We stock marine-grade replacements and install them as a permanent fix.
- Multi-point lock mechanisms binding from sand and grit. On Premium and Classic-Craft models, the locking gear sits fully exposed to coastal air, and fine sand from the beach works its way into the track. The lock starts sticking, then refuses to throw all points. We disassemble, clean, realign, and swap in stainless Tru-Defense assemblies when the original gear is beyond saving.
- Weatherstripping erosion on east-facing doors. Doors that face the Atlantic on streets like South Ocean Boulevard take direct ocean air, and the frame weatherstripping breaks down faster than the slab itself. You’ll feel a draft at the threshold or see water intrusion at the jamb during squalls. We replace with OEM Therma-Tru compression seals that actually fit the frame profile.
- Hardware corrosion on hinges and handle sets. Salt air doesn’t care about the brand stamp. We’ve pulled Therma-Tru hinges off five-year-old doors in Palm Beach that look like they spent twenty years underwater. We source marine-grade stainless replacements when the originals are too far gone to recondition.
Therma-Tru Service in Palm Beach: What Local Conditions Mean for Your Equipment
Palm Beach is a true barrier island, less than half a mile wide for most of its length, with the Atlantic on one side and the Lake Worth Lagoon on the other. Every home here gets salt-laden air from two directions simultaneously, which is why aluminum hardware and frame components on Therma-Tru doors fail years faster than they do in West Palm Beach or Boynton Beach. We see it most on the mid-island streets, where 1920s and 1930s Mediterranean Revival homes still stand with original entryways that were never designed for impact-rated replacements.
Add to that the reality of the Town of Palm Beach’s Architectural Commission, ARCOM for short. If your property is on the historic registry, you’re not just pulling a building permit. You need ARCOM pre-approval before anyone touches a door or window, and ARCOM meets on a set monthly schedule. Miss the submittal deadline and you’re waiting three to four weeks before you can even file the permit paperwork. That timeline reality is built into every estimate we write for island properties.
Therma-Tru Models & Products We Service in Palm Beach
We work on the full Therma-Tru residential lineup: Classic-Craft, Smooth-Star, Pulse, and Tru-Defense entry systems, plus their fiberglass and steel door slabs, frames, and multi-point locking hardware. Our parts approach is straightforward. We use OEM Therma-Tru replacement sweeps, corner seals, and sill caps whenever lead time allows, because OEM parts fit the first time. But when a door is beyond ten years old with corroded aluminum components, we’ll tell you honestly: replacing one part at a time often costs more than switching to compatible Tru-Defense or aftermarket marine-grade stainless hardware that will outlast the next decade of salt air.
For hurricane-prone Palm Beach, we emphasize Impact Windows in Palm Beach, hurricane-proof front and entry doors, and full frame replacements. We repair what we can. When a full frame replacement is the only way to meet current Palm Beach impact requirements, we’ll say so flat out and give you a written line-item quote with no surprises.
Therma-Tru Service Pricing in Palm Beach
What drives the cost of Therma-Tru service on the island: the condition of the existing frame, whether the door needs OEM or marine-grade replacement hardware, and whether ARCOM review applies to your property. A simple weatherstripping replacement runs less than a full multi-point lock swap, and a delaminated slab on a Classic-Craft door costs more than a sill cap replacement. You’ll get a written estimate before any work starts, and the price on that estimate is the price you pay. No change orders, no vague “plus materials” lines. Call (561) 782-7525 and we’ll come out, look at the actual door, and tell you what it costs to fix. Estimates are free.

FAQs - Therma-Tru Windows & Doors in Palm Beach
Generally no. Therma-Tru’s warranty covers manufacturing defects in the door slab and finish, not environmental corrosion from coastal salt air. Hinges, sill caps, and multi-point lock hardware typically fall under limited coverage and exclude damage from atmospheric conditions. What does cover you in practice: our Done Right Promise. If we install a part and it fails because of how it was put in, we make it right. For the salt-air reality Palm Beach homeowners face, we recommend marine-grade stainless hardware as a permanent upgrade. Call (561) 782-7525 and we’ll assess what your door actually needs.
Yes, but only if the door matches the original profile and character, and you secure ARCOM pre-approval before any work begins. ARCOM meets on a monthly schedule, and missing the submittal deadline pushes your project back three to four weeks before you can even pull a permit. This means a Therma-Tru door on a designated historic property often needs custom milling or an ARCOM-approved surround and hardware package. We’ve done this on Mediterranean Revival homes across the island, including a 1930s Classic-Craft entry on South Ocean Boulevard where the replacement cleared ARCOM conditions and restored the design pressure rating. We handle the paperwork and the installation. Call (561) 782-7525 to discuss your property.
The bubbling isn’t floodwater. It’s salt-laden moisture wicking up from the bottom rail, where the slab meets the sill. Palm Beach’s dual-salt-air environment means condensation and salt spray settle on the door base constantly, and the moisture works its way under the fiberglass skin. Over time, the skin delaminates and forms visible bubbles. The fix depends on how far the delamination has progressed. We repair minor cases and replace the slab when the structure is compromised. Call (561) 782-7525 and we’ll tell you which path you’re on after one look.
Yes, in many cases. Florida Building Code requires that any replacement door or window meet current wind-load requirements, and for a barrier island like Palm Beach with no inland buffer, that effectively means impact-rated glazing and a door rated for 180+ mph wind pressure. There’s no grandfathering on Palm Beach Window Installation work. The good news: Therma-Tru’s Tru-Defense line and compatible impact-rated models satisfy those requirements, and we’ll pull the permits and coordinate with ARCOM where historic review applies. Call (561) 782-7525 for an exact quote on your specific door.
We start by checking the frame square and the door’s weight bearing. Sandy soil, especially on the mid-island streets where footings shift seasonally, causes doors to settle, and once the slab is out of plane, the multi-point lock pins bind against the frame strike. We realign the hinges, adjust the slab, and if the lock gear is sand-damaged, we swap in a stainless Tru-Defense assembly that won’t bind up the next time a summer storm blows grit against the door. It’s a permanent fix, not a lube job. Call (561) 782-7525 to schedule a free estimate.
