Therma-Tru Windows & Doors in Miami, FL | Winslow Windows & Doors
We provide Therma Tru sales & service and install doors and windows throughout Miami as an independent contractor, not a manufacturer-authorized dealer. What separates our Therma-Tru work here is that we understand Miami-Dade’s High-Velocity Hurricane Zone code and how salt air from Biscayne Bay chews through door hardware faster than any other Florida market. When you call Winslow Windows & Doors at (727) 620-6983, you’ll get a straight answer about whether your Therma-Tru unit needs a seal repair, a hinge replacement, or a full-frame retrofit to meet NOA requirements.
Why Miami Residents Choose Us for Therma-Tru Service
Ed Winslow learned building construction at Miami Dade College before putting his name on a truck, and he still lives in the same zip code he grew up in near Tamiami Park. That means the Therma-Tru doors we repair on SW 8th Street or in Kendall belong to neighbors, not job tickets. We’ve worked on Classic-Craft, Fiber-Classic, Smooth-Star, and Benchmark units in Miami’s CBS ranches and Brickell high-rises since 2011. Our techs arrive background-checked and in uniform. And every call is answered by a live person, day or night. No call centers, no ticket numbers. Just Ed’s word, backed by the Done Right Promise. If it’s not done right, we make it right. Period.
Common Therma-Tru Windows & Doors Problems We Solve in Miami
- Bottom rail rot on Classic-Craft doors. Miami’s summer downpours dump an inch of rain in an hour. Water wicks through a worn threshold or failed corner seal pad, saturates the foam core in the bottom rail, and the door starts sagging within a season. We replace the seal, reinforce the lower hinge, and reset the sweep so water stops getting in.
- UV and salt-air breakdown of weatherstripping on Smooth-Star doors. On bayfront and beachside properties, the compression weatherstripping turns brittle in three to five years. You’ll feel air moving around the door and see daylight at the corners. We replace it with OEM Therma-Tru weatherstripping because the dimensional fit matters under HVHZ wind loads.
- Hinge-side sag on heavy Classic-Craft doors. A lot of 1980s CBS homes in West Miami and Hialeah got beautiful Mahogany Collection doors installed with cheap non-ball-bearing hinges. Two decades of daily use plus humidity means the leaf wears, the door drops, and the latch misses the strike plate. We swap in ball-bearing hinge sets and align the slab.
- Finish delamination on Fiber-Classic doors with southern exposure. Reflected UV off concrete driveways and patios breaks down the capstock coating on Fiber-Classic Oak Collection doors within 10 to 12 years in Miami. The fiberglass starts to bloom and peel. We can refinish early-stage delamination; advanced cases usually mean a new slab is cheaper than saving the old one.
- Swell-and-stick lock stile issues after storms. We pulled a Fiber-Classic from a 1962 CBS ranch off SW 8th Street in Little Havana last month. Every afternoon storm, the door would not latch. The bottom rail foam core had absorbed water through a failed corner seal and pushed the lock stile out of the strike plate. We replaced the OEM corner seal pad, added lower hinge reinforcement, replaced the compression weatherstripping, and reset the frame. A smoke pen test confirmed a 25% reduction in air infiltration.
Therma-Tru Service in Miami: What Local Conditions Mean for Your Equipment
Here is the part that matters and most homeowners never hear: Miami-Dade requires every replacement door or window installed after 1994 to carry a Miami-Dade Notice of Acceptance. Thousands of Therma-Tru entry doors in Miami went in as non-impact units under older codes or without permits. You cannot legally replace one with a like-for-like non-impact door today. That means a full-frame replacement to an impact-rated Therma-Tru fiberglass door or another code-compliant alternative. This is not a Broward problem and it is not a Palm Beach problem. It is a Miami reality, and it changes the entire repair-versus-replace conversation. In Hialeah and Little Havana, we regularly see original Therma-Tru doors from the 1990s that would fail any current NOA review. Homeowners call thinking they need a hinge adjusted and learn the whole unit is non-compliant. We tell them the truth before we ever touch a drill.
Therma-Tru Models & Products We Service in Miami
We work on the Classic-Craft Mahogany Collection, Fiber-Classic Oak Collection, Smooth-Star fiberglass doors, and the entry-level Benchmark line. When a part is available, we use Therma-Tru OEM replacement weatherstripping, corner seal pads, door sweeps, hinge sets, and strike plates. OEM fit matters because air and water resistance under HVHZ loads depends on exact dimensional tolerance. When an OEM part is discontinued or backordered beyond three weeks, we recommend only marine-grade aftermarket hardware with equal or better corrosion resistance. And we are blunt when blunt is needed: if the slab itself has blown foam core separation or hinge stile rot, replacing the door unit is cheaper than repairing it. We also handle Impact Windows in Miami, hurricane-proof front and entry doors, and full-frame replacements across the area.

FAQs - Therma-Tru Windows & Doors in Miami
No. Any replacement door in Miami-Dade installed after 1994 must carry a Miami-Dade Notice of Acceptance. If your current Therma-Tru door is non-impact and non-compliant, a like-for-like replacement is not legal. We will walk you through impact-rated Therma-Tru options or code-compliant alternatives that fit your opening. Call (727) 620-6983 to find out what your home actually needs.
It is water, not humidity. Miami’s afternoon storms force water through a worn corner seal pad or failed threshold, and the foam core in the bottom rail absorbs it. The frame swells, the lock stile pushes out of alignment, and the door will not latch. The fix is replacement of the OEM seal pad, hinge reinforcement, and a full-perimeter reseal. Call (727) 620-6983 and we will diagnose it properly.
Yes. Under HVHZ code, any glazed opening in an exterior door must meet Miami-Dade impact standards. Decorative glass inserts in a Therma-Tru door count as glazed openings. If your inserts are not impact-rated, the door is non-compliant and potentially uninsurable under current Citizens underwriting rules. We can source compliant inserts for Therma-Tru doors in Miami.
Expect 10 to 12 years on a directly exposed Fiber-Classic unit before the capstock coating shows visible delamination. Salt spray, direct UV, and no shade accelerate finish failure on Miami barrier islands and Brickell high-rises. Early-stage finish bloom can sometimes be refinished; advanced delamination means the slab has reached the end of its service life. Call (727) 620-6983 for an honest assessment and a free estimate.
Usually not. HVHZ retrofits require the entire door assembly to meet impact standards as a single NOA-listed unit. Mixing a new impact slab with an old non-impact frame breaks the certification and will fail inspection. Full-frame replacement is the correct approach for any Miami Window Installation, and we pull permits and pass inspections on every retrofit. Call (727) 620-6983 to schedule your free estimate.
