Therma-Tru Roof Repair in Coral Gables: What to Know First
Therma-Tru roof repair in Coral Gables is not a sideline for us. We are an independent Therma-Tru service provider, and we repair, replace, and re-flash Therma-Tru skylights, roof-adjacent door units, and the flashing systems that surround them. Most Therma-Tru roof repair jobs we complete in a single visit. Pricing runs on a written, line-item quote before any work begins, typically $395 to $1,850 depending on what failed.
This page is for Coral Gables homeowners who own a Therma-Tru entry door or patio door with a transom, sidelight, or overhead glazing system and now have a leak, a fogged panel, or a sagging header. If that is you, call (954) 507-3613. A live person answers, day or night, and we will tell you honestly whether the repair is worth doing.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds fiberglass and steel entry systems. The roof-adjacent components are where Coral Gables weather finds the weak points. Here are the failures we see repeatedly, and what we actually do about them.
- Therma-Tru Classic-Craft transom and sidelight flashing delamination. The Classic-Craft line often pairs a fiberglass door with an overhead transom. In Coral Gables, the repeated afternoon downpour cycle swells the rough opening, and the factory flashing tape lifts at the corners. Water does not show at the transom. It travels down the king stud and puddles behind the threshold. We remove the exterior trim, cut back the failed flashing, and re-flash with a self-adhering membrane lapped shingle-style so water sheds outward, not inward.
- Fiber-Classic/Pulse overhead door panel leaks at the head jamb. When a Therma-Tru door sits under a shallow overhang or a flat roof edge, wind-driven rain hits the head jamb at pressure. The factory weatherstrip was never designed for that exposure. We see this on the Pulse line in older Coral Gables homes along Granada Boulevard and the Riviera section. The fix is a combination of a deeper drip cap, a sealed head flashing, and re-kerfed weatherstrip. No amount of caulk alone fixes this.
- Smooth-Star transom glass fogging. Therma-Tru transoms and door lites are insulated glass units, and the seal fails exactly the way a window seal fails: the desiccant saturates, the argon leaks out, and fog appears between the panes. On a Smooth-Star unit fifteen or more years old, the glass usually is not worth saving. We replace the IGU with a new one cut to the same overall thickness, set it in fresh glazing tape, and re-seal the stop. The door frame stays put.
- Rotted sub-sill under Therma-Tru thresholds. The Therma-Tru door itself is fiberglass and will not rot. The wood sub-sill under it will, especially in Coral Gables where irrigation overspray hits the threshold every morning. The homeowner sees water at the interior floor and blames the door. The real culprit is the untreated pine the original builder set under the threshold. We pull the door, replace the sub-sill with pressure-treated stock or composite, re-set the unit, and re-flash. That is a one-day job for us and the fix lasts.
- Multi-point lock misalignment after roof settlement. In sections of Coral Gables with older masonry construction, roof load shifts over decades and the rough opening settles fractionally. A Therma-Tru multi-point lock that once threw all three points now hangs at the top. Homeowners replace hardware first, and the new hardware still binds. We re-shim the jamb, re-square the panel, and only then adjust the lock. On Therma-Tru units, shimming from the hinge side is the repair. Replacing hardware is a waste of money until the unit is true.
Our Therma-Tru Roof Repair Process
Every Therma-Tru repair follows the same order of operations. Nothing gets skipped, and the truck does not leave until the test passes.
- 1
Call and diagnosis. You call (954) 507-3613. A live person answers, asks what you are seeing, and schedules the visit. We show up during the window we give you, not sometime later that week.
- 2
Inspection and root-cause finding. A background-checked, uniformed technician measures everything twice and finds why the leak or failure happened. We photograph what we find and show you on site.
- 3
Written line-item quote. Before any work starts, you get the price on paper with the specific parts, the specific labor, and the warranty terms. No verbal handshakes on price. The quote holds.
- 4
Parts decision, stated plainly. Where a quality aftermarket part matches or exceeds OEM spec, we say so and price accordingly. Where OEM is the only choice that makes sense, we say that too and order the Therma-Tru part. You never pay twice because we chose the wrong part first.
- 5
The repair. We execute the fix: flashing, glass, sub-sill, or hardware, set plumb and square. Every opening is measured twice. Every seal is tooled, not smeared.
- 6
Water test and cleanup. We test the repair with water where a water test applies, walk you through what we did, register warranty layers in writing before the truck leaves, and sweep up. If it is not right, it gets fixed under the Done Right Promise.

What moves the price: masonry opening repairs, rot extending beyond the sub-sill, and whether the door is an oversized custom unit. Every quote is a fixed number on paper before you decide. Call (954) 507-3613 and we will put numbers to your specific job. Estimates are free.
Why Coral Gables Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We have served Coral Gables and the surrounding communities since 2008. Dale Kessler founded this company in 2008, but the craft tradition behind it goes further back: he learned glazing from his father, who re-glazed storefronts along the Miracle Mile when Dale was still too young to carry the caulk gun unsupervised. That is not a story. That is how the name TruePane got here.
When a Coral Gables homeowner calls about a Therma-Tru product, the technician who arrives knows the brand’s weak points and fixes the actual cause, not the symptom. If a full replacement is the honest answer, we quote Therma-Tru alongside other lines we service, including PGT, CGI, CWS, and ES Windows, so you can compare numbers side by side on paper. Every job carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before the truck leaves the driveway. If the pane is not true, the job is not done.
Frequently Asked Questions
No. Therma-Tru’s written warranty covers manufacturing defects in the door slab, frame, and components. Independent service work on the flashing, glass, or surrounding structure does not void that coverage. We are an independent Therma-Tru service provider, and we document every repair so you have a clear record of what was done and why. If you want certainty before we touch the unit, call (954) 507-3613 and we will explain exactly how the layers apply to your specific door.
We schedule most non-emergency Therma-Tru repairs within a few business days. A live person answers the phone around the clock, so you are never leaving a message and waiting for a callback. If water is coming through the opening and damaging drywall or flooring, tell us that when you call. We adjust the schedule for active water intrusion.
It depends on what failed and the age of the unit. A fogged transom on an otherwise sound door is a repair. A rotted sub-sill with a straight frame is a repair. A door panel that has delaminated, a frame that has racked beyond shimming, or hardware that is no longer manufactured for that model year pushes toward replacement. We will quote both where that applies, in writing, side by side. You decide with the numbers in front of you. Call (954) 507-3613 for an honest read on your specific door.
We use genuine Therma-Tru parts when OEM is the right call, and we use proven aftermarket parts when they equal or exceed the original spec. The decision is made per part and stated on your quote before work begins. We never sell you a “Therma-Tru equivalent” without telling you what it is and why we chose it. If it is not in writing, it is not a guarantee - it is just a conversation.
No. The number on your written quote is the number on the bill. If we open the wall and find rot or structural damage that no inspection could have seen, we stop, show you, re-quote the added scope in writing, and wait for your approval before proceeding. There are no surprise line items and no change orders hidden on the back of the invoice. That has been our practice in Coral Gables since day one.
