We service and install Therma-Tru doors across Palm Beach, from oceanfront estates to historic Mediterranean Revival homes, and also offer our Window Replacement in Palm Beach. Our work focuses on one thing most contractors miss here: keeping Therma-Tru fiberglass and steel units standing up to salt air, hurricane wind loads, and landmark review boards without sacrificing the architectural character of the house. If your Therma-Tru door is binding, fogging, or showing rust at the hinges, call (728) 203-1160 and we’ll send someone who knows the product line cold.
Why Palm Beach Residents Choose Us for Therma-Tru Service
We’ve worked on Classic-Craft, Fiber-Classic, and Pulse series doors in enough Palm Beach homes to know where they fail and why. Keith Yamada, who runs our West Palm Beach operation, trained in the building trades at Los Angeles Trade-Technical College and spent years working through every stage of Palm Beach Window Installation: measuring, flashing, finishing, and standing in front of a homeowner at the end of the day to make sure nothing was left undone. That background matters when you’re dealing with a Therma-Tru door that a previous installer shimmed wrong in a 1920s opening. We’re an independent Therma-Tru service provider, not a factory-authorized shop, which means we recommend the fix that actually fits your door and your budget, not the one a manufacturer approval process tells us to push.
We keep genuine Therma-Tru OEM weatherseals, hinges, and multi-point lock hardware on hand for fast turnaround in Palm Beach. When it makes sense, we’ll recommend a quality aftermarket glass pack or a composite threshold that outperforms the original spec. Every job starts with a written price before any work begins, and every crew member wears shoe covers and lays drop cloths before touching a door. That’s the Cedarwell Care Promise, and it’s been our operating rule since 2010.

Common Therma-Tru Windows & Doors Problems We Solve in Palm Beach
- Delaminating fiberglass skins on south-facing doors. Prolonged UV exposure and salt air intrusion cause Therma-Tru door skins to separate at the edges, especially on homes along South Ocean Boulevard where afternoon sun is relentless. We assess whether the skin can be re-bonded or if the slab needs replacement, and we never recommend a full door when the frame is still square.
- Failed corner seals on Slim-Line sliding patio doors. Storm-driven rain and wind pressure find weak corner seals fast. You’ll notice fogging between the glass or a draft at the corners. We re-glaze with impact-rated insulated units and re-seal the corners with marine-grade sealant that holds up to Palm Beach humidity.
- Rusted or binding hinges and weatherstripping. Oceanfront homes see constant salt spray, and Therma-Tru hinges are not immune. We replace with stainless steel hinges and OEM weatherstripping, then adjust the reveal so the door swings clean without dragging on the threshold.
- Misaligned frames from previous non-specialist installs. Older Mediterranean Revival openings are rarely square, and a door shimmed wrong loses its energy seal and starts binding within a season. We re-hang the slab, correct the shims, and flash the opening properly so the door closes the way Therma-Tru designed it to.
- Drafty multi-point locks on Classic-Craft entry units. The multi-point system only works when the door is hung plumb and the keepers align. We adjust the strikes, replace worn lock rods, and restore the full weather seal, which matters a lot during a Palm Beach summer thunderstorm.
Therma-Tru Service in Palm Beach: What Local Conditions Mean for Your Equipment
Here’s what most out-of-town techs don’t understand about Palm Beach. The Landmarks Preservation Commission frequently requires that replacement doors on pre-1940 estates keep the original lite pattern and panel profile. That means you can’t just drop in any Therma-Tru slab and call it done. We’ve seen approval letters denied because the divided lites were an inch off or the panel profile read modern instead of period. Therma-Tru’s Classic-Craft line is actually a smart choice here because the fiberglass can be customized with a woodgrain finish and lite configuration that matches the original woodwork, and it meets impact code at the same time. But only if the installer documents the match properly for the landmarks board. We do that documentation, including photos, spec sheets, and side-by-side profile comparisons, so your approval doesn’t stall. Keith’s crew has done this kind of work throughout the El Cid neighborhood, where older homes demand careful framing and respect for the original character of the structure.
Therma-Tru Models & Products We Service in Palm Beach
We work on the full Therma-Tru lineup that shows up in Palm Beach homes: the Classic-Craft Mahogany Collection, the Fiber-Classic Oak Collection, the Pulse Series (Smooth-Star), and Slim-Line Patio Door Systems. For critical components like weatherseals, hinges, and multi-point locking hardware, we use genuine Therma-Tru OEM parts. For glass packs and composite thresholds, we’ll recommend quality aftermarket options when they match or beat OEM specs and save you money. We keep common OEM parts stocked locally so most Palm Beach service calls don’t wait on a factory shipment. If your fiberglass skin is intact and the frame is sound, we repair and re-hang before recommending a full replacement. That’s the honest order of operations.

AfterTherma-Tru Service Pricing in Palm Beach
What you’ll pay depends on what’s actually wrong. A hinge replacement with OEM hardware runs between $180 and $340 in most Palm Beach homes. Weatherstripping and threshold replacement typically lands between $250 and $500. Repairing a delaminating fiberglass skin starts around $400 and goes up based on the size of the affected area and whether we need to color-match the woodgrain finish. Full slab replacement for a Classic-Craft or Fiber-Classic door runs between $1,500 and $4,200 installed, depending on size, glass package, and finish. Impact-rated glass adds to that number. Every free estimate includes a written line-item price before work starts, so you know exactly what the job costs. Call (728) 203-1160 and we’ll walk the door with you and put the number in writing.

FAQs – Therma-Tru Windows & Doors in Palm Beach
Yes, in many cases we can re-bond the skin if the delamination is caught early and the underlying slab is sound. We use an epoxy injection process that stabilizes the fiberglass and restores the door’s structural integrity. If the delamination has spread across a wide area or the core is compromised, a new slab makes more sense. Call us at (728) 203-1160 and we’ll assess your door in person. Estimates are free.
Therma-Tru offers impact-rated configurations that do meet Palm Beach’s high-velocity hurricane zone requirements, but not every model in every glass package qualifies. The door must be specified with impact-rated glass and the proper frame anchoring for your opening. We verify the engineering documents for your specific model and confirm what your home actually needs under current code. Call (728) 203-1160 to have us check your door’s ratings.
Salt spray is relentless. Standard hinges on any door, including Therma-Tru’s, will eventually show rust when exposed to constant coastal air. Palm Beach oceanfront homes accelerate that timeline significantly. We replace rusted hardware with stainless steel hinges and use marine-grade fasteners so the new components hold up far longer.
Yes. Therma-Tru’s Classic-Craft and Fiber-Classic lines offer woodgrain finishes that can be matched to your existing door, but it takes care. We take a sample or detailed photos of your current finish and work with the staining process to get a close match, then seal it for UV protection before installation. If a perfect match isn’t possible on an older, sun-bleached door, we’ll tell you that before you spend a dollar.
Therma-Tru fiberglass doors resist warping better than wood or steel, but extreme heat and direct afternoon sun stress any door. The finish may fade, weatherstripping can degrade faster, and an improperly installed slab may shift. We recommend a UV-protective finish, stainless hardware, and a proper installation with correct shimming. Call (728) 203-1160 for an exact quote on your door. Estimates are free and come in writing.
