Therma-Tru Windows & Doors in Coral Gables, FL | Winslow Windows & Doors

Winslow Windows & Doors provides independent Therma-Tru repair, retrofit, and full-frame replacement across Coral Gables. We’re not a Therma-Tru dealer or manufacturer affiliate, which means we diagnose honestly and fix what’s actually wrong. The one thing that makes our Therma-Tru work here different: we know Coral Gables’ dual approval process, the Historic Preservation Board and Miami-Dade NOA, inside and out, so your door or window doesn’t stall in permitting limbo. Call (863) 251-5864 for a straight answer and a free estimate.

Why Coral Gables Residents Choose Us for Therma-Tru Service

Most crews can swap a door. Few can tell you why a Classic-Craft slab bows on a western exposure off Alhambra Circle, or why the sweep on a Benchmark unit facing the bay fails two years early. We can, because we’ve been pulling permits and fitting Therma-Tru products into Coral Gables’ masonry openings for years, and because Ed Winslow learned the trade through Miami Dade College’s Building Construction Technology program before putting his own name on the truck. Ed’s crew has spent years working Westchester’s ranch homes and Coral Gables’ Merrick-era Mediterranean Revival houses, and there isn’t much about a Therma-Tru jamb he hasn’t seen. We carry OEM parts for in-production lines and machine our own Delrin and aluminum replacements for discontinued legacy hardware, so a sticking Benchmark latch doesn’t become a two-week wait on a backordered part. Ed’s name is on the door, and on every job we do.

Common Therma-Tru Windows & Doors Problems We Solve in Coral Gables

  • Rot at the bottom stile/rail joint on Classic-Craft doors. Coral Gables’ bay-facing neighborhoods, like the eastern streets near Biscayne Bay, get wind-driven salt spray that sits on thresholds and wicks into the bottom rail joint. We cut out the rot, rebuild the rail with marine-grade material, and reseal with a moisture barrier that holds up to salt air far better than the original factory seal.
  • Failed door sweeps and compression seals on Benchmark units. Coral Gables sits between the Bay and the urban heat island, which means prolonged high heat and intense sun exposure chew through foam compression seals years faster than the manufacturer’s expected service life. We replace sweeps and seals with UV-stable material and verify the door’s reveal so the new sweep actually contacts the threshold evenly.
  • Thermal bowing of fiberglass skins on dark-painted Classic-Craft doors. A dark finish soaking up western exposure on streets like Costanera or Segovia can bow the slab just enough that the deadbolt misses its strike. We correct this by re-hanging the slab, adjusting hinge geometry, or replacing the slab into the original masonry opening when the bow has set permanently.
  • Corrosion of pre-2000 steel screw bosses and brass weatherstrip retainers. Coral Gables’ humidity never really lets up, and older Therma-Tru doors built before stainless and composite hardware became standard show it first. We pull the corroded fasteners, machine matching aluminum or Delrin replacements, and re-bed everything with a corrosion-inhibiting sealant so it doesn’t seize up again in two years.
  • Latch misalignment from the building settling into CBS walls. Coral Gables’ original masonry homes don’t move the way frame construction does, but decades of thermal cycling crack and shift the jamb embedment. We re-mortise strike plates, realign the latch, and reinforce the jamb anchor points so the door closes square and seals tight.

Therma-Tru Service in Coral Gables: What Local Conditions Mean for Your Equipment

Here’s the thing most contractors learn the hard way in Coral Gables: on a contributing Merrick-era home, the Building and Zoning Department won’t even accept a permit application for a Therma-Tru door until the Historic Preservation Board has signed off on the replacement design. That means the hinge finish, the escutcheon, the threshold profile, even the glazing bar pattern on a lite, all have to be documented and submitted before the first inspection gets scheduled. It’s a pre-permit step that adds four to six weeks and doesn’t exist in Pinecrest, South Miami, or unincorporated Miami-Dade. For a Therma-Tru owner, that changes the math: a simple slab swap might not be so simple if the Board requires the replacement to match a 1930s bronze escutcheon that’s no longer made, or demands a custom-radius arched unit instead of an off-the-shelf rectangle. We’ve walked enough jobs through this process to know which Therma-Tru models and finishes clear the Board quickly, and which ones need custom fabrication before the application goes in. If you own a Therma-Tru door on a designated historic structure, start with someone who’s been through that review already.

Therma-Tru Models & Products We Service in Coral Gables

We service the full Therma-Tru lineup that shows up in Coral Gables homes: the Classic-Craft American Style Collection, the Classic-Craft Rustic Collection, Benchmark by Therma-Tru Entry Doors, and the Pulse Series. For in-production lines like Benchmark and Pulse, we use OEM Therma-Tru parts because hinge and sweep geometry are tolerance-dependent and aftermarket copies rarely seat correctly. For discontinued legacy Therma-Tru doors, we machine Delrin or aluminum replacement parts with profiles that match the originals. We repair rather than replace whenever the slab is structurally sound and the hinge system isn’t wallowed, especially in older Coral Gables homes where the jamb is embedded in historic CBS and pulling it means busting out masonry. Our Therma-Tru sales & service page goes deeper on the brand specifics.

Therma-Tru Service Pricing in Coral Gables

Independent Therma-Tru repair in Coral Gables runs between $180 and $340 for most smaller fixes: a door sweep replacement, a latch realignment, a weatherstrip swap. A slab replacement on a Classic-Craft or Benchmark door typically lands in the $900 to $2,200 range depending on size, finish, and whether we’re fitting it to a standard rectangle or an arched masonry opening. Full frame replacement into a historic CBS jamb with all the preservation paperwork starts around $2,500 and goes up with custom glass and hardware. What drives cost here more than anywhere else is the approval path: a pre-permit Historic Preservation Board review, custom radius fabrication, and NOA documentation all add time and money. Your free estimate with us is a written, line-item quote; you’ll see exactly what’s labor, what’s parts, and what’s fees before you sign anything. Call (863) 251-5864 and we’ll walk the job with you.

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
★★★★★

"We sat out a hurricane behind the windows Ed put in. The gusts threw a neighbour's trampoline down the street and the loudest thing in our house was the kettle. I rang him after to say thank you and he answered his own phone, same as always."

TThaddeus Okonkwo
★★★★★

"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
★★★★

"Excellent work and a fair price for what it is, though impact glass is never cheap and one bedroom window arrived with a scratched pane. Ed flagged it before I saw it and the replacement went in without me chasing anyone."

BBartholomew Crenshaw
★★★★★

"Ed measured every opening himself and walked me through the product approval paperwork before I signed anything. When the inspector came he found the notice of acceptance taped inside a window like it should be and passed us first visit."

RRosalind Beaumont
★★★★

"The installation was clean and the windows are beautiful. The factory took about six weeks to deliver the units, which Ed told me upfront, but living behind plywood-framed openings in the meantime still tested my patience."

GGuadalupe Zamorano
★★★★★

"A tile roof repair and new windows from the same company meant one crew, one permit runner, and nobody blaming the other trade. Ed checked the roof work himself before the tarp came off."
