Therma-Tru Windows & Doors in Miami, CA | Juniper Windows & Doors
We handle Therma Tru sales & service for entry doors, patio doors, and impact-rated fiberglass systems across Miami. The one thing that makes our Therma-Tru work here different is simple: we verify every door against Miami-Dade County’s separate NOA product approval system before we order or install anything. Call (682) 281-2168 to schedule a free estimate, and you’ll get a written price before any work starts.
Why Miami Residents Choose Us for Therma-Tru Service
We’ve replaced and repaired hundreds of Therma-Tru Benchmark, Smooth-Star, Classic-Craft, and Fiber-Classic units in this city. Sean Mackey, our owner, grew up in Silverlake and trained at Los Angeles Trade-Technical College, where he focused on building envelope fundamentals. That background matters here: Miami’s heat, humidity, and salt air expose every weak point in a door’s construction, and Sean can spot the failures before they become a full replacement. We’re just as thorough with the repair itself. We source genuine Therma-Tru parts whenever the manufacturer still makes them. If the line is discontinued, we use aftermarket components that meet or beat the original spec. Every job gets a written price first, and our 365-Day Done Right Promise covers the work for a full year, parts and labor, in writing.
Common Therma-Tru Windows & Doors Problems We Solve in Miami
- Cracked or delaminating fiberglass door skins. Therma-Tru Smooth-Star and Classic-Craft entries can crack along the edges after years of intense UV and salt-air exposure. We see this most often on west- and south-facing elevations in Miami, where the sun beats on the slab all afternoon.
- Swelling at the bottom rail on Benchmark entries. When a Benchmark door is installed without proper weep management, wind-driven rain from tropical systems gets past the sill and saturates the composite substrate. The slab swells, the door drags, and eventually the bottom rail starts to separate. We fix the sill and, when the slab is too far gone, replace it with an impact-rated unit.
- Corroded multipoint lock hardware on Classic-Craft doors. Near the coast, salt air works its way into the lock cartridge. You’ll feel it first as stiffness in the handle, then as a door that won’t latch fully. That is a security issue during storm season, so we address it quickly.
- Chalked and faded factory finishes. Therma-Tru’s factory-applied stains and paints look great for a few years, then start to chalk in Miami’s year-round sun. We refinish with high-UV marine-grade topcoats that hold up far longer than the original finish.
- Failed weatherstripping and sweeps. The rubber and vinyl components on any door break down faster in Miami’s humidity. We replace sweeps, weatherstripping, and sills to restore the seal and lower your cooling bill.
Therma-Tru Service in Miami: What Local Conditions Mean for Your Equipment
There is one fact about Miami that changes how Therma-Tru work has to be done here, and it is not about the weather. Miami-Dade County runs its own product approval system, called NOA, and it is separate from Florida’s statewide product approval. That means a Therma-Tru door that meets Florida code may still need a Miami-Dade NOA number to pass inspection or insurance review in this county. In practice, we have had jobs where a perfectly good Therma-Tru entry door had to be re-ordered or swapped because the NOA listing did not cover the exact configuration the homeowner wanted. We check the NOA listing on every door before we order it. No exceptions. That matters especially for homeowners in areas like Coral Gables, where inspectors are strict and insurance carriers ask for proof of compliance. We also provide Therma Tru service in Hialeah with the same thorough NOA verification.
Therma-Tru Models & Products We Service in Miami
Our team works on the full Therma-Tru residential lineup: the Benchmark Collection entry doors, Smooth-Star fiberglass doors, Classic-Craft series, and Fiber-Classic patio doors. For discontinued Benchmark or older Fiber-Classic lines, we use aftermarket parts that meet or exceed the original specification, and we will tell you that upfront. We stock common replacement hinges, sills, sweeps, lock cartridges, and glass inserts for fast turnaround in Miami and Therma Tru in Pembroke Pines, which means less downtime between diagnosis and repair. If you are deciding between repair and replacement, we will give you an honest answer. After years of Miami sun and salt, replacement is often the smarter long-term investment.
Therma-Tru Service Pricing in Miami
Therma-Tru service in Miami typically runs between $150 and $1,200 depending on the repair. A simple weatherstripping or sweep replacement is on the low end. Lock hardware replacement and refinishing fall in the middle. A full slab replacement with an impact-rated door runs higher, and the final number depends on the specific Therma-Tru model, finish, and Miami-Dade NOA requirements. Here is what you can expect:
- Weatherstripping, sweeps, or sill replacement: $150 to $400
- Lock cartridge or hardware replacement: $275 to $600
- Fiberglass skin repair or refinishing: $400 to $900
- Full entry door slab replacement with impact-rated Therma-Tru unit: $2,800 to $5,500
Every estimate includes a written line-item breakdown. No vague ranges, no changes at the door. Call (682) 281-2168 for an exact quote.

FAQs – Therma-Tru Windows & Doors in Miami
Yes. Miami’s combination of intense UV exposure, high humidity, and salt air means you should inspect the finish, weatherstripping, and hardware every six months. We recommend refinishing factory-applied stains and paints with a high-UV marine-grade topcoat well before they begin to chalk. The lock cartridge should be lubricated annually, especially within a few miles of the coast. Call (682) 281-2168 if you want us to do a maintenance check.
In most cases, you can replace just the slab if the frame is structurally sound and square. We do slab replacements regularly in Miami, especially on Smooth-Star and Benchmark entries. The catch is that the new slab still has to meet Miami-Dade NOA requirements, and sometimes the existing frame is too far gone from moisture or termite damage. We will tell you which applies after an on-site inspection.
Some are, but not all. Therma-Tru manufactures impact-rated doors that carry Miami-Dade NOA numbers, but you cannot assume every model qualifies. We verify the NOA listing for the exact door and configuration before ordering. That is the difference between passing inspection and having a very expensive door sent back. Call (682) 281-2168 with your model number and we will check it for you.
Near the coast, that is almost always internal corrosion inside the multipoint lock cartridge on Classic-Craft doors, or a worn cylinder on Benchmark hardware. Salt air works into the mechanism and the parts bind up. We replace the cartridge or hardware with genuine Therma-Tru parts when available, then lubricate and adjust the door so it latches cleanly. Call (682) 281-2168 and we will get it turning smoothly again.
In Miami, expect 15 to 25 years from a well-maintained Therma-Tru door before the slab, frame, or hardware needs major work. Doors on west- and south-facing elevations, or within a mile of the coast, tend to age faster due to sun and salt. We have replaced Miami doors that looked fine at ten years but had hidden bottom-rail swelling, and we have serviced Classics from the early 2000s that are still solid. Location matters more than the brand.
