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.

FAQs - Therma-Tru Windows & Doors in Coral Gables
Therma-Tru warranties are tied to the product and, in most cases, the original installation. As an independent service provider, we are not a Therma-Tru authorized dealer, so we can’t process warranty claims on their behalf. That said, we use OEM Therma-Tru parts on in-production lines precisely so the components themselves remain covered under the manufacturer’s part warranty where applicable. Call (863) 251-5864 and we’ll tell you straight whether your repair falls inside or outside the warranty window before we touch anything.
Yes, in most cases. The Classic-Craft and Benchmark lines are still in production, so we can order a replacement slab with the same stile and rail profile, the same panel layout, and the same finish color as your original, then fit it to your existing jamb or fabricate a new jamb to match the historic opening. For true historic contributing properties where the Board requires matching original bronze or brass hardware, we coordinate the submittal and the installation. Call (863) 251-5864 and we’ll start with a photo review of your door and a straight answer on feasibility.
Some Therma-Tru models do, and some don’t. Therma-Tru manufactures impact-rated versions of several door lines, but the NOA, the Notice of Acceptance from Miami-Dade County, is product-specific and tied to the exact configuration, glass package, and frame, which is why Impact Windows in Coral Gables must meet the same strict standards. A Therma-Tru door without a Miami-Dade NOA cannot be installed as a new or replacement exterior door in Coral Gables. We verify the NOA for your specific door model and glass package before we quote the job, so you don’t pay for a door that won’t pass. Call (863) 251-5864 and we’ll pull the NOA records for the model you’re considering.
Summer humidity in Coral Gables causes the fiberglass slab and the wood or composite jamb to swell, which closes the reveal between the door edge and the strike side jamb. Combined with afternoon heat that thermally expands the slab, the latch bolt drags or hangs up on the strike plate. We fix it by adjusting the hinge geometry, shaving the strike side slightly, or re-mortising the strike plate, usually in under an hour. It’s a common Coral Gables seasonal issue, and it rarely requires a new door. Call (863) 251-5864 if your latch is hanging up; we’ll take a look.
Yes, if the crack is in the skin and hasn’t breached the underlying core. We sand back the gel coat, fill the crack with a color-matched, UV-stable fiberglass filler, refinish the area, and reseal the edge. For bay-facing doors in Coral Gables, we also inspect the bottom rail and threshold seal for salt damage at the same time, since a skin crack and a salt-rotted rail often come as a pair. Call (863) 251-5864 and we’ll tell you whether it’s repairable or whether the salt has gotten deeper than the surface.
