Therma-Tru Construction in Orlando, FL | Penhallow Remodeling Orlando
We provide independent Therma-Tru door service across Orlando, from College Park bungalows to Lake Nona new builds. The one thing that makes our Therma-Tru work here different: we know how these doors fail in Florida’s specific humidity, afternoon thunderstorms, and hurricane cycles, and we fix them with that knowledge in mind. If you need Therma-Tru repair, weather sealing, or a full impact-rated replacement, call (850) 427-6454 for a free estimate. Trevor Nash and the General Contractor - Orlando crew have been working on these doors across the metro for years.

Why Orlando Residents Choose Us for Therma-Tru Service
We’re not a manufacturer affiliate. We’re an independent remodeling contractor who has handled Orlando Bathroom Remodeling and Therma-Tru entry and patio door systems across hundreds of Orlando jobs. That independence means we tell you straight when a door can be saved with OEM parts and when it’s smarter to replace the whole unit. Trevor Nash grew up in Los Angeles and learned construction at Los Angeles Trade-Technical College before spending two decades on slab foundations and finish carpentry. He’s been serving Orlando homeowners long enough to know what 1950s-era framing looks like up close in College Park, and how a 2006 Therma-Tru Smooth-Star reacts to ten years of irrigation overspray. We carry OEM Therma-Tru weatherstripping, corner seal pads, and adjustable thresholds for jobs where alignment and sealing matter most. For hinges, screws, and multi-point lock bodies where OEM lead times drag or cost spikes, we use quality aftermarket parts and tell you why. Every job gets a written price before work starts, and every repair carries our 365-Day Done Right Promise in writing.

Common Therma-Tru Construction Problems We Solve in Orlando
- Warped or swollen fiberglass door slabs. West-facing entries without proper overhangs take the brunt of afternoon downpours from June through September. The slab itself can soften and swell, especially at the bottom corners. We assess whether the slab can be re-hung with adjusted thresholds or if full replacement is the honest call.
- Failed weatherstripping and corner seal pads. Southwestern exposure plus Orlando’s summer thunderstorm pattern means seal pads dry out, crack, and let water into the rough opening. We replace these with OEM pads when available and re-caulk the brickmold to stop water before it reaches the jamb.
- Rusted or seized hinge screws and threshold screws. Central Florida’s humidity combined with irrigation overspray near entryways corrodes fasteners faster than homeowners expect. A door that drags or won’t latch may just need hardware replacement, not a new slab.
- Cracked glass lite frames from windborne debris. During named storms, even impact-rated glazing can take a hit that cracks the lite frame. We replace the glass lite and frame, and we check the surrounding door slab for stress before reinstalling.
- Misaligned multi-point locking systems. Orlando’s wet season and dry season cause subtle expansion and contraction. Over years, that cycle knocks multi-point locks out of alignment. We adjust, repair, or replace the lock body based on what the hardware actually needs.
Therma-Tru Service in Orlando: What Local Conditions Mean for Your Equipment
Here’s a fact that shapes how we approach Therma-Tru work in Orlando and not in Kissimmee or St. Cloud the same way: Orlando’s older neighborhoods like College Park and Delaney Park have a high number of original 1920s to 1950s wood-frame homes with unpermitted additions and outdated framing. When a Therma-Tru door on one of these houses fails, the door is rarely the whole story. The rough opening may have settled, the header may be undersized, or a previous owner may have cut a new opening without a permit. We open the trim and look at the framing before we quote a replacement. A new impact-rated Therma-Tru Classic-Craft installed into a compromised opening will fail the same way the old one did. Trevor’s experience with older Orlando construction means we catch these issues and tell you before we order the door. That’s the difference between patching a symptom and fixing the structure.
Therma-Tru Models & Products We Service in Orlando
We service the full range of Therma-Tru residential product lines, including the Classic-Craft Mahogany Collection, Fiber-Classic Oak Collection, Smooth-Star Collection, and the Pulse Series patio doors. For parts, our approach is simple: when alignment or sealing is critical, we install OEM Therma-Tru weatherstripping, corner pads, and adjustable thresholds. When OEM lead times stretch out or costs are unreasonable, we use high-quality aftermarket hinges, fasteners, and multi-point lock bodies and explain the tradeoff clearly. We maintain a local parts inventory for the most common Orlando failure points, which means we can often complete weatherstrip and lock repairs without waiting on a distributor shipment. Doors over 15 years old with slab warping or delamination usually need a full replacement with a modern impact-rated Therma-Tru unit. We’ll tell you that in the first conversation, not after we’ve opened the wall.

FAQs – Therma-Tru Construction in Orlando
Therma-Tru fiberglass doors hold up far better than wood in Orlando’s high humidity, but they are not immune to failure. What we see most often is bottom-corner swelling on doors with irrigation overspray or missing drip caps. The slab itself can absorb moisture at exposed edges over years. Proper installation with a drip cap, caulked brickmold, and an adjustable threshold makes the difference. If your door is already spongy at the corner, call (850) 427-6454 for an assessment.
In most cases, you need a replacement door slab or a full unit. Retrofitting impact-rated glass into an existing Therma-Tru slab is rarely cost-effective and may compromise the door’s structural integrity. We’ll look at the slab, the frame, and the glass lite size, then give you options with real numbers. A free estimate gets you the exact answer.
That’s the classic Orlando wet-dry cycle. During the humid months from June through November, the door slab and the wood frame absorb moisture and expand. In the cooler dry months, they contract. The fix is often a threshold adjustment or a minor hinge tweak, not a new door. We can correct this in one visit usually. Call (850) 427-6454 for a quote.
If the corner pad has disintegrated and moisture has reached the slab interior, the honest recommendation is usually replacement. Fiberglass slabs can’t be structurally patched the way wood can. We’ll confirm by pulling the old slab and inspecting the rough opening. A new impact-rated Therma-Tru unit installed properly will last far longer than the original. Get a free estimate at (850) 427-6454.
Orlando’s wind mitigation requirements and insurance discount eligibility depend on your specific home, its location, and your insurer’s criteria. Impact-rated Therma-Tru doors with proper glazing and anchoring may qualify for wind mitigation credits. We can tell you what your existing door has and what a replacement would need. Call (850) 427-6454 and Trevor will walk you through it.
