Therma-Tru Windows & Doors in Delray Beach, FL | Winslow Windows & Doors
We provide independent Therma-Tru door and window service across Delray Beach, from the oceanfront condos on the 33483 ZIP’s east side to the CBS ranch neighborhoods west of Federal Highway. The thing that makes our Therma-Tru work here different is that we lead every service call with a salt-air failure inspection, because in Delray Beach, the salt-laden Atlantic air corrodes door sills and hardware about twice as fast as it does just a few miles inland. We’re the locally owned crew Ed Winslow built, and we answer the phone around the clock at (561) 816-5648. Call us for a free estimate on any Therma-Tru repair or replacement, whether it’s a Classic-Craft entry door or a Benchmark sliding patio door.
Why Delray Beach Residents Choose Us for Therma-Tru Service
Our crews work on Therma-Tru door and window systems daily across Delray Beach, and we know how their fiberglass skins, composite frames, and hardware hold up in salt-laden coastal air and under wind-borne debris requirements. We stay independent on purpose. No manufacturer quota pushes us toward selling you a new door when a rebuilt sill and fresh weatherstripping will do the job. Ed Winslow grew up in Miami and learned early that South Florida weather doesn’t forgive sloppy work. He studied building construction technology at Miami Dade College before spending the better part of two decades doing windows and doors one job at a time. That’s why we stock genuine Therma-Tru parts, sweeps, adjustable sills, corner pads, and weatherstripping, locally, so we can turn around most Delray Beach repairs without waiting on a distributor.
We’re not a call center and we’re not a national chain. We’re the one down the road, with a published address, a license number, and Ed’s name on every job. When a Palm Beach County inspector walks up to a door we hung, we want it to pass the first time. Every Delray Beach installation is Impact Windows in Delray Beach rated or paired with approved opening protection, because Palm Beach County’s wind-borne debris region requirements don’t leave room for guesswork. If it’s not done right, we come back and make it right. That’s the 36500-Day Done Right Promise.
Common Therma-Tru Windows & Doors Problems We Solve in Delray Beach
- Fiberglass skin delamination at the bottom rail. Along East Atlantic Avenue and the oceanfront condos in 33483, standing saltwater splash and sprinkler overspray eat away at the bottom edge of fiberglass door slabs. We see Classic-Craft and Smooth-Star doors with peeling skins that have lifted entirely from the rail, and sometimes the fix is a rebuild, sometimes a replacement. We’ll tell you which one makes sense for your door.
- Corroded adjustable sill caps and corner gaskets. The persistent onshore breeze in Delray Beach carries salt crystals that settle into every seam on a Classic-Craft entry door. The adjustable sill cap corrodes, the corner gaskets turn brittle, and air and water start seeping in around the threshold. We replace these with genuine Therma-Tru parts and reseal the opening.
- Weatherstripping compression set on Benchmark sliding patio doors. In the 1950s CBS homes near Carver High School, the original Benchmark sliding doors have been in place for decades. The weatherstripping flattens and loses its seal, which means drafts and an A/C unit running harder than it should. We swap in OEM compression-set-resistant sweeps and the door seals like it should.
- Sticking or misaligned door slabs in masonry openings. Concrete block houses settle. It happens, especially in the older neighborhoods off Southeast 6th Avenue. The rough opening shifts slightly, the door slab binds against the frame, and nobody wants to fight their front door every morning. We re-shim and re-anchor the frame to the masonry and the door swings true again.
- Jalousie-to-impact-window swaps that expose door problems. A lot of Delray Beach homeowners come to us to replace jalousie windows with impact-rated units, and while we’re there, they ask about the old Therma-Tru door that’s been leaking for years. We handle both, so the whole opening, window and door, is compliant and sealed at the same time.
Therma-Tru Service in Delray Beach: What Local Conditions Mean for Your Equipment
Here’s something we tell every Therma-Tru owner in the 33483 ZIP: if your entry door is east of Federal Highway, its bottom sweep and adjustable sill are corroding twice as fast as the same model a mile west near Carver High School or Hidden Lake Park. The Atlantic is on one side and the Intracoastal is just blocks inland on the other, so the salt load isn’t an occasional thing. It’s constant. The onshore breeze pushes salt crystals into the sill track, the corner gaskets, and the weatherstripping every single day. A 15-year-old Therma-Tru door in coastal Delray Beach can look like a 30-year-old unit in Orlando. That’s not a reason to avoid fiberglass doors. It’s a reason to service them on a schedule and use genuine Therma-Tru parts when you do. We quote every door repair or replacement in this area with a salt-air failure inspection first, because most of these jobs are driven by sill corrosion, not by anyone wanting a cosmetic upgrade.
Last month our tech was called to a 1960s CBS ranch west of Federal Highway near Carver High School where a Benchmark by Therma-Tru sliding patio door was sticking halfway open. The adjustable sill cap had corroded and lifted, catching the door slab every time the homeowner tried to slide it. We cleaned the sill track, replaced the cap and weatherstripping with genuine Therma-Tru parts, and re-shimmed the frame to correct for the settled masonry opening. The door now slides easily and seals tight for hurricane season. That’s the kind of repair that makes more sense than a full replacement, and it’s the kind of work we do every week in this city.

That covers entry doors, hurricane-proof front and entry doors, French doors, and double doors.

FAQs - Therma-Tru Windows & Doors in Delray Beach
Salt air, plain and simple. The 33483 ZIP sits between the Atlantic and the Intracoastal, and the onshore breeze deposits salt on your door’s sill cap, corner gaskets, and weatherstripping continuously. That salt accelerates corrosion at roughly double the inland rate. Regular replacement of the sill cap and weatherstripping with genuine Therma-Tru parts is the fix. Want an exact assessment? Call (561) 816-5648 and we’ll inspect it for free.
No. Palm Beach County’s adopted Florida Building Code places Delray Beach in the wind-borne debris region, so any new or replacement door must be impact-rated or paired with approved shutters. This applies even to interior-unit condo replacements. We pull the permit, install compliant units through our Window Installation in Delray Beach, and make sure the inspection passes.
The most common failure we see in oceanfront condos is fiberglass skin delamination at the bottom rail, driven by standing saltwater splash and sprinkler overspray. The skin separates from the rail and moisture gets in. Sometimes it’s a rebuild; sometimes it’s a slab replacement. We’ll tell you which one is worth your money. Call (561) 816-5648 for a straight answer and a free estimate.
We re-shim and re-anchor the frame. Concrete block homes settle over time, and the rough opening shifts slightly, causing the door slab to bind or hang out of square. We remove the door, assess the opening, and re-shim the frame to correct the misalignment before reinstalling. It’s a standard fix in the 1950s-1970s CBS neighborhoods west of Federal Highway.
Surface cracks alone usually don’t warrant replacement. If the slab’s structural integrity is intact, we can repair the skin, replace the weatherstripping and hardware, and reseal the door. Replacement makes sense when the slab or frame shows structural compromise. We’ll give you an honest recommendation, because we’re independent, with no sales quota pushing us toward new units. Call (561) 816-5648 for a free assessment.
