Why Palm Beach Homeowners Choose Therma-Tru Windows & Doors
Winslow Windows & Doors provides Therma Tru repair in Palm Beach, FL, including independent windows and doors service and installation throughout the barrier-island estates along El Brillo Way and the mid-century CBS homes on the north end. What separates our Therma-Tru work from a generic handyman’s is simple: our technicians have spent years field-testing these specific fiberglass door slabs, multi-point locks, and weather-stripping systems in South Florida’s salt-air climate, so we know exactly how they fail and what actually fixes them. We are an independent service provider, not a Therma-Tru authorized dealer or warranty agent, which means our only loyalty is to the homeowner paying the invoice. Call (561) 831-7863 any time to describe what your door is doing, and Ed Winslow or one of our techs will tell you straight what you’re looking at.
Why Trust Winslow Windows & Doors for Your Therma-Tru Windows & Doors?
Our field knowledge of Therma-Tru products comes from thousands of independent installs and repairs across Palm Beach County and Therma Tru service in West Palm Beach, not from flipping through a manufacturer’s training binder. We have seen how the Classic-Craft Mahogany Collection’s fiberglass skins react to unrelenting Atlantic salt spray, how the Pulse Series entry doors’ multi-point hardware behaves when Palm Beach humidity sits at 90 percent for six straight weeks, and how Q-Lon weather-stripping degrades faster on a barrier island than it does ten miles inland. That experience means we arrive at the diagnosis faster and we do not replace parts that are still serviceable.
Ed Winslow started this company in 2011 after growing up in Miami and learning the trade the hard way, on real job sites helping his uncle weatherproof homes after summer storms. He trained in construction technology at Miami Dade College and has been on ladders and door frames ever since. His name is on the truck, and his phone rings 24/7 because we answer it live, every time. When a Palm Beach homeowner calls us about a Therma-Tru door that will not latch, they get a background-checked, uniformed technician who knows the difference between a Fiber-Classic Oak and a Smooth-Star Fiberglass unit before the first screw comes out. Like Ed says, “My name’s on the truck. That’s reason enough to do it right.”
Common Therma-Tru Windows & Doors Problems We Fix in Palm Beach
These are the Therma-Tru issues we see most often on the island and surrounding areas. Each one has a specific cause, and each one has a repair path that works.
- Bowed or delaminating fiberglass door skins. The Classic-Craft Mahogany Collection and Fiber-Classic Oak Collection use molded fiberglass skins that can separate from the core or bow outward under relentless UV and salt-air exposure. We regularly see doors on east-facing Palm Beach estates that have baked in direct Atlantic sun for a decade. The fix is usually a re-set and re-seal, not a full slab replacement, but only if the delamination is caught before moisture reaches the foam core.
- Jamming or binding multi-point lock mechanisms. Pulse Series and Classic-Craft entry doors use multi-point locks that throw bolts at three points along the frame. Palm Beach humidity swells the wood frame and the slab, which throws the lock off its tightening sequence. We disassemble, clean, lubricate with a marine-grade product, and reset the strike alignment. A new lock is rarely needed. A new frame is sometimes the honest answer.
- Warped or cracked door frames causing air leaks and misalignment. We see this on CBS homes on the north end of Palm Beach where water has wicked into an unsealed bottom corner. The frame twists, the reveal goes uneven, and the door drags. We can often correct reveal with a frame reset or shim adjustment. If rot has set in, we do a full frame replacement, usually with a composite or treated substrate that outlasts the original.
- Failed Q-Lon weather-stripping that no longer seals against rain bands. Summer squalls push horizontal rain against entry doors across Palm Beach. Once the Q-Lon compression seal loses its memory or tears, water drives through the gap. We replace it with genuine Therma-Tru Q-Lon, because aftermarket foam substitutes compress too much and let water in within a season.
- Sagging Therma-Tru French door panels that scrape the threshold. French door configurations using Therma-Tru slabs put significant weight on the hinges. We routinely adjust or replace hinges, reset the panel reveal, and in some cases install a higher-capacity hinge system so the panel clears the threshold without scrape marks. It is a one-visit fix in most cases.
Therma-Tru Parts & Our Repair-vs-Replace Approach
When we touch a Therma-Tru door, we use genuine Therma-Tru components for anything structural or sealing: slabs, frames, weather-stripping, multi-point lock hardware, and corner seals. Third-party substitutes rarely fit the tight tolerances Therma-Tru builds into their products, especially on the Q-Lon extrusion and the multi-point strike plates, and a sloppy fit means the door fails again. For cosmetic pieces, like interior trim or non-structural brickmould, we offer quality aftermarket options when the goal is saving the homeowner money without compromising the door’s weather seal or structural integrity. We keep a local stock of common Therma-Tru sealing parts and multi-point components so most Palm Beach repairs happen in one visit, not three.
If you are debating whether to repair or replace your Therma-Tru door, call (561) 831-7863 and we will give you a straight read. Sometimes a $40 adjustment solves it. Sometimes the honest call is a new slab.
Our Therma-Tru Service Process - Step by Step
- 1
Diagnosis. Our technician inspects the slab, frame, hinges, weather-stripping, and lock hardware on site. We identify the exact Therma-Tru series (Classic-Craft, Fiber-Classic, Smooth-Star, Pulse) and confirm the failure mode before quoting anything. Palm Beach salt-air corrosion gets checked specifically on all hardware and exposed metal surfaces.
- 2
Repair or install. We use genuine Therma-Tru parts for all structural and sealing components. For full replacements, we order the correct slab or frame configuration to match your existing reveal, threshold, and trim. On the island, we also coordinate with any applicable ARCOM requirements when an exterior change is visible.
- 3
Test. We do not leave a job until the door passes a water-spray test with a garden hose, the multi-point lock engages on all three points, and the slab clears the threshold without scraping. For impact-rated windows, we verify proper seating and seal integrity.
- 4
Warranty. Every job carries the 36500-Day Done Right Promise. If it is not done right, we make it right. Period.

FAQs - Therma-Tru Windows & Doors Service in Palm Beach
Yes, in most cases. The rust you are seeing on the bottom of a Therma-Tru fiberglass door is almost always on a steel door sweep or an edge channel, not on the fiberglass slab itself. We remove the corroded component, treat the area, and install new hardware with a marine-grade finish rated for Palm Beach salt exposure. If water has wicked up into the slab edge and caused internal corrosion, we will tell you honestly and quote a replacement. Call (561) 831-7863 and describe what the bottom of the door looks like, and we will give you a straight answer before a truck rolls.
A multi-point lock that is hard to turn is usually a misalignment problem, not a lock problem. The slab has shifted or the frame has swelled from humidity, which puts the multi-point gearbox off its neutral axis. We take the lock assembly apart, clean it, lubricate it with a product that holds up in South Florida’s humidity, and reset the strike alignment. Most of these are fixed in a single visit without replacing the door or the lock. We have done this repair on dozens of oceanfront condos in Palm Beach.
In most cases, no. Impact-rated doors are not just a glass upgrade; the slab, frame, hinges, and anchoring must all be engineered as a system to meet Florida Building Code wind-load requirements for our high-velocity design zone. You cannot retrofit impact performance onto a non-impact Therma-Tru slab. What we can do is install properly rated Impact Windows and doors, and we will quote the full system with the glass, frame, and anchoring required. For Palm Beach addresses especially, this is the only path that actually holds up to the wind-load math and ARCOM’s review requirements.
Chalking is UV degradation of the exterior finish layer, and it is accelerated here in Palm Beach because the island is exposed to sun from the Atlantic side and reflected light off the Intracoastal. A faded Therma-Tru door can often be restored with the right surface prep and marine-grade finish system, but it is a specialized job. We will tell you if a refinish is worth it or if the underlying slab has degraded to the point where a new door is the smarter move. Call (561) 831-7863 for an honest assessment.
Yes. A scraping French door panel typically means the hinges are worn or the frame reveal has shifted, which is very common in Palm Beach humidity. We reset the panel, adjust the hinges, and in many cases upgrade to a hinge with a higher load rating so the problem does not return next season. Threshold scraping should be addressed quickly, because continued scraping will chew up the threshold seal and invite water intrusion. One visit is usually all it takes.
Therma-Tru service in Palm Beach typically ranges from $150 to $650 for repairs like weather-stripping replacement, lock adjustments, and threshold resets, while full door or impact window replacement runs from $2,000 to $4,000 per opening depending on size, impact rating, and finish options. These are real ranges from our local pricing, not generic national numbers. Call (561) 831-7863 for an exact quote on your door, and remember our standing offer: $40 off any repair over $200.
