Therma-Tru Windows & Doors in Miami Beach, FL | Winslow Windows & Doors

We provide independent Therma-Tru service and installation across Miami Beach, from South Beach’s historic Art Deco corridors to the condo towers along Collins Avenue. The one thing that makes our Therma-Tru work different here is the dual compliance burden: Miami-Dade NOA hurricane approval plus Miami Beach Historic Preservation Board sign-off on the same door or window. Call (863) 656-0462 and you’ll reach a live person who can walk through what your building needs before a tech ever pulls up.

Why Miami Beach Residents Choose Us for Therma-Tru Service

We’ve repaired and replaced Therma-Tru entry doors, French doors, and Impact Windows in Miami Beach on this barrier island long enough to know which frame materials, glazing packages, and hardware actually survive here. That knowledge comes from the field, not a product brochure. Ed Winslow grew up in Miami and spent three decades learning what South Florida salt air does to a poorly installed door. His crew has worked older condos near the Faena District, single-family homes off the boulevard, and mid-rise buildings where the HOA wants everything done yesterday.

We’re an independent service provider for Therma-Tru sales & service, not a factory-authorized shop. That independence matters more on Miami Beach than anywhere else in Florida, because it lets us pair genuine Therma-Tru OEM parts with marine-grade stainless hardware whenever salt spray demands it. No corporate script telling us what we can and cannot do on a 1930s door surround. We stock the common failure parts locally so turnaround is measured in days, not weeks. And every call is answered by a person, 24/7. Ed’s name is on the door and on every job we do. That keeps him honest.

Common Therma-Tru Windows & Doors Problems We Solve in Miami Beach

  • Salt-seized hinges and threshold hardware. Therma-Tru steel door hinges and adjustable threshold screws corrode fast when Atlantic spray and Biscayne Bay humidity combine. We regularly replace seized adjustment screws on Classic-Craft and Fiber-Classic entry doors so the slab stops sagging and dragging on the sill. Stainless aftermarket fasteners go back in.
  • Fiberglass slab warping on west-facing exposures. A Therma-Tru Fiber-Classic door that bakes in the afternoon Bay sun day after day can warp enough to break the weatherseal contact at the top or latch side. We level or replace the slab when it’s too far gone, and we check the reveal before we leave.
  • Weatherstripping failure from salt-caked weep holes. Therma-Tru double-hung window balances and weatherstripping gum up when weep holes clog with packed salt crystals. Water backs up into the track, the strip tears, and then air leaks start. We clear the tracks, replace the weatherseal, and show owners where the weep holes live.
  • Failed mullion seals on multi-panel patio doors. Hurricane-driven rain hits multi-panel Therma-Tru patio units broadside on Miami Beach, and once the mullion seal lets go, water travels into the frame and the floor underneath. We re-seal or rebuild mullions with marine-grade material rated for lateral wind pressure.
  • Chalky door finish after two or three salt seasons. The clear coat on a Therma-Tru Classic-Craft fiberglass door breaks down early in Miami Beach’s salt-laden air, leaving a hazy white film. More than cosmetic, it leaves the skin vulnerable. We strip, re-coat, and recommend a UV-stable marine finish that holds up here.

Therma-Tru Service in Miami Beach: What Local Conditions Mean for Your Equipment

Miami Beach is the only U.S. jurisdiction where a Therma-Tru door or window replacement on a contributing Art Deco or Mediterranean Revival building must simultaneously carry a Miami-Dade NOA impact approval and a Certificate of Appropriateness from the Historic Preservation Board. No other city imposes that double burden. The result is that on Ocean Drive and the lower Collins Avenue corridor, we often pair a standard Therma-Tru impact door slab with custom-preserved historic framing or muntin patterns that replicate the original 1930s slim sightlines. A mainland contractor never navigates that. A generic “Therma-Tru installer” doesn’t either. If your building is one of the 800-plus contributing structures, the product selection and the paperwork both have to be right before a screw comes out of the existing opening. We handle the approval package because we’ve done it enough times to know exactly what the Board’s staff will flag and what sails through.

How much does Therma-Tru service cost in Miami Beach? Most hardware repairs, weatherseal replacements, and threshold adjustments on a Therma-Tru door run between $180 and $340 depending on the part and how much salt removal is involved. Historic district work is different, and we cover that below.

Therma-Tru Models & Products We Service in Miami Beach

We service and install the full residential Therma-Tru line that South Florida homeowners actually buy: the Classic-Craft Collection, Fiber-Classic, Smooth-Star, and the Pulse line for more modern openings. That covers entry doors, French doors, patio sliders, and the impact-rated window units Therma-Tru pairs with them. For repairs, we source genuine Therma-Tru OEM parts whenever possible, especially fiberglass door skins, composite sills, and multi-point lock hardware. Where the island’s salt spray beats up standard hardware faster than the factory ever intended, we substitute marine-grade stainless hinges, fasteners, and sweeps. We repair before replacing only when the frame is structurally sound and the failure is isolated to hardware, weatherseals, or glazing. A rusted-out or water-damaged unit on a historic building usually goes to full-frame replacement with NOA and Preservation Board pre-approval.

Therma-Tru Service Pricing in Miami Beach

Service Typical Cost in Miami Beach
Door hardware repair (hinges, threshold, lock adjustment) $180 - $340
Weatherseal / weatherstripping replacement per door or window $95 - $210
Door balancing, sagging slab correction, and reveal adjustment $160 - $290
Full Therma-Tru entry door replacement (standard, non-historic) $2,100 - $4,600 installed
Full Therma-Tru impact door with Miami-Dade NOA in historic district $4,800 - $11,000+ (paperwork and Board approval included)

What moves the price on Miami Beach is the paperwork, the salt damage underneath what you can see, and whether the Historic Preservation Board has to weigh in. A free estimate gets you a written line-item quote covering the part, the labor, and any approval processing, so the number you see is the number that holds. We don’t do change orders on repair work, and we’ll tell you flat out if repair is throwing money at a door that should be replaced. Call (863) 656-0462 and we’ll set it up.

Will the price change once work starts? Not on quoted repair work. We wrote it down, it holds. The only time a quote changes is if we uncover rot or structural damage behind a frame that was invisible from the outside, and we’ll stop and show you photos before any additional work is approved. Call (863) 656-0462 for an exact quote on your door or window, estimates are free.

Reviews

What Neighbors Say About Winslow Windows & Doors

★★★★★

"The old aluminium sliders howled every afternoon storm and swelter came straight through the glass. The new impact sliders shut with a sound like a bank vault and the back rooms finally hold their temperature."

PPercival Whitcombe
★★★★★

"He replaced the front door and the garage door in the same week, both rated for impact, and lined the frames up so straight my level had nothing to say. My wife stopped hearing the highway from the front room."

MMaximilian Vasquez
★★★★★

"Three big companies quoted us and every one sent a salesman with a leased truck. Ed turned up in a truck with his own name on the door, quoted less, and his crew were the same faces on day one and day nine."

YYolanda Betancourt
★★★★★

"Our insurance agent asked for the wind mitigation paperwork and Ed had the whole file ready the day the job closed, every opening photographed. The premium conversation went very differently this year."
