Call (786) 418-6182 to schedule your free measured survey; the written quote we leave with you is the same document that governs the job.
Why Leisure City Residents Choose Us for Therma-Tru Service
We’ve worked on Therma-Tru doors across South Miami-Dade since 2012, and Leisure City’s mix of pre-Andrew concrete-block homes and 1993-2000 rebuilds presents a specific diagnostic challenge. The post-Andrew stock often has first-generation impact units with hardened silicone and corroded hardware; the older homes frequently received replacement doors during early rebuilds that carried NOAs now expired or never updated for current product runs. We know both histories because we’ve documented them.
Our Therma-Tru sales & service approach is independent. We’re not bound to sell new slabs when an OEM hardware set and proper sill-pan detail will solve the problem, and we’re not restricted from recommending full replacement when the slab is cracked, the frame is pitted, or the NOA won’t pass Miami-Dade inspection. Sonia Raman, who leads our crew, grew up in Miami and trained at Miami Lakes Educational Center - where instructors graded square cuts and repeatable measurements, not theory. She still pulls AAMA performance standards on slow Fridays. That background shows up in how we specify: frame depth, glass thickness, and DP rating matched to what the Florida Building Code and the structure actually require, not what fits a price sheet.
Every Leisure City job starts with a measured survey you keep. Our technicians are background-checked, uniformed, and identified by license number before arrival. The 365-Day Done Right Promise applies to every opening we touch.
Common Therma-Tru Windows & Doors Problems We Solve in Leisure City
- Gel-coat micro-cracks on fiberglass slabs. After 25+ years of Leisure City’s UV intensity, Therma-Tru Smooth-Star and Fiber-Classic doors develop hairline fractures in the composite skin. Humidity penetrates and swells the slab edges, especially near Biscayne Bay’s salt-air load. We see this most on west-facing doors in the 1993-2000 rebuild stock.
- Multi-point lock corrosion and hinge seizure. Therma-Tru’s steel multi-point mechanisms and hinges oxidize aggressively in Leisure City’s coastal environment. Doors stick, sag, or fail to latch fully - a critical failure during HVHZ wind-load testing and insurance inspections. One seized lock can red-tag an entire opening.
- Perimeter seal failure on NOA-lapsed units. Pre-Andrew homes that received Therma-Tru doors during early rebuilds often have original glazing with silicone that hardened and cracked. The door looks structurally sound but leaks driving rain. The NOA may have lapsed years ago, leaving the homeowner technically non-compliant.
- Bottom rail rot on patio French doors. Therma-Tru French door bottom rails and astragal seals absorb standing water from Leisure City’s flat-lot drainage during summer thunderstorms. The hinge stile separates from the frame. We’ve replaced slabs on SW 144th Avenue where the composite was wicking water for two seasons before the homeowner noticed sticking.
- Frame pitting and hardware failure from salt air. Even current NOA-approved Therma-Tru units suffer accelerated frame pitting in Leisure City compared to inland Florida cities. Stainless-steel hardware upgrades are not optional here; they’re the difference between a five-year and a fifteen-year service life.

AfterTherma-Tru Service in Leisure City: What Local Conditions Mean for Your Equipment
Leisure City sits inside Miami-Dade County’s High Velocity Hurricane Zone - the most stringent Impact Windows & Doors in Leisure City regulatory environment in the United States. Every replacement unit must carry a current Miami-Dade County Notice of Acceptance, not merely standard Florida Building Code approval. This is not a bureaucratic distinction. Miami-Dade’s NOA system rejects many impact-rated products approved everywhere else in Florida, so contractors who routinely work in Broward or Monroe County and carry that inventory into a Leisure City job frequently get red-tagged on inspection.
For Therma-Tru owners, this means a door that looks perfect can still fail inspection and leave you uninsured for storm damage. We’ve found NOA-lapsed Therma-Tru Classic-Craft units in Leisure City homes where the homeowner had no idea the original certification expired with that product run. The door functioned. The lock worked. The inspector still failed it. Our supplier relationships are specific to HVHZ-approved product lines because that’s the only inventory that clears inspection in this municipality. Measure it right the first time. The wall does not accept revisions.
Therma-Tru Models & Products We Service in Leisure City
We service the full range of Therma-Tru entry and patio door systems found in South Miami-Dade homes: Smooth-Star fiberglass entry doors, Classic-Craft American Style collection, Fiber-Classic series, and patio French and sliding glass door units. Our stock for Leisure City service area calls includes OEM Therma-Tru hardware, astragals, and hinge sets, plus quality aftermarket multi-point locks and weatherseals that meet HVHZ performance requirements.
We do not stock non-HVHZ inventory. If your Therma-Tru unit requires a part that lacks current Miami-Dade approval, we’ll tell you before ordering, not after installation. When the slab is sound and the NOA is current, repair makes sense. When the composite is cracked through, the frame is pitted to structural compromise, or the NOA cannot be brought current, we recommend full replacement with a documented photo record of why.

FAQs - Therma-Tru Windows & Doors in Leisure City
Yes. We specify only Therma-Tru units with current Miami-Dade County NOAs, which is the standard that governs Leisure City. We do not install products approved only under standard Florida Building Code. Call (786) 418-6182 to verify NOA status on your specific model.
Yes, if the slab and frame remain sound and the NOA is current. We source OEM Therma-Tru multi-point locks and stainless-steel hinge sets for coastal environments. If corrosion has spread to the strike plate or the frame mortise, we’ll document that and quote the additional repair. Call (786) 418-6182 for an exact quote - estimates are free.
Flat-lot drainage in Leisure City leaves standing water against bottom rails during summer thunderstorms, and the salt-air load accelerates degradation of seals that would last longer inland. Therma-Tru French door astragals and bottom rails are particularly vulnerable because the design creates a water trap. We address this with Miami-Dade-compliant sill-pan detailing and upgraded weatherseals, not just slab replacement.
No. An expired NOA cannot be renewed retroactively. The door must be replaced with a current NOA-approved unit to pass inspection. We will show you the documentation gap, photograph the existing unit for your records, and quote replacement with a valid product. Call (786) 418-6182 to schedule the survey.
Yes, and these require particular attention. Pre-Andrew homes in Leisure City often have original single-pane aluminum frame windows and non-impact door openings that are wholly non-compliant with current HVHZ code. We measure the rough opening, specify the correct Therma-Tru impact-rated replacement, and pull the required permits. The 365-Day Done Right Promise applies.
