How Therma-Tru Products Fail, and How We Fix Them
Therma-Tru builds solid door systems, but twenty years of Wellington sun, rain, and wind finds the weak points. Here are the five failure modes we see most often on Therma-Tru roof assemblies in this area, and what we do about each one.
- Rot at the top jamb corners on Classic-Craft and Fiber-Classic lines. Therma-Tru’s fiberglass skins hold up well, but the wood frame behind them does not forgive standing water. In Wellington, afternoon storms drive rain sideways against north-facing entries, and the top corners are where water sits. By the time a homeowner notices the door sticking at the top, the jamb is already soft. We pull the unit, cut out the rotted framing, sister in new treated stock, and reset the door so the reveal is even all the way around.
- Cap flashing separation on Smooth-Star systems with transom windows. The flashing Therma-Tru ships with these units is functional, but installers who rush the job often nail it flat instead of lapping it under the weather barrier. The result is a slow leak that shows up as a water stain on the interior drywall two or three years later. We remove the old flashing, inspect the sheathing behind it, and install new cap flashing lapped correctly with a positive slope away from the opening.
- Sill pan failure on patio door roof assemblies. Therma-Tru patio systems in Wellington sit under roof overhangs that channel water directly onto the sill. The original sill pan, typically a thin plastic or aluminum piece, cracks after years of UV exposure and thermal cycling. Water then wicks into the subfloor. We replace the pan with a heavier-gauge material, slope it outward, and seal the end dams so water exits the opening instead of pooling under the door.
- Header sag above double doors in Market Street and Pulse lines. Wellington homes built in the 1990s and early 2000s often have headers that were undersized for the opening width. We see this most on double-door configurations where the header carries more load than a single door. The sag shows up as a gap at the top of the active slab, a door that rubs at the strike side, or a visible bow in the interior trim. We install a properly sized engineered header, reframe the opening, and reset the door to factory tolerances.
- Weep hole blockage on Classic-Craft doors with brickmould. Therma-Tru designs weep holes into the bottom rail of many door slabs, but Wellington’s wind-blown pollen and fine sand from the Everglades edge clog them within a few seasons. Water that cannot drain through the weep holes backs up into the door core. We clear the weep paths, verify the drainage channels are open, and in cases where the core has already absorbed water, we recommend replacement rather than a repair that will fail again in two years.
Our Therma-Tru Roof Replacement & Installation Process
Here is how a Therma-Tru roof replacement job runs when you call TruePane Windows & Doors.
- 1
Call and describe the problem. A live person answers at (561) 349-4826, day or night. We’ll ask what you’re seeing: water stains, sticking, gaps, visible rot, or a door that will not latch.
- 2
We measure and diagnose on site. A background-checked, uniformed technician comes out, checks the roof line with a level, opens the trim where needed, and identifies exactly what has failed. No guessing over the phone.
- 3
We quote OEM and aftermarket side by side on paper. You’ll see the Therma-Tru part, a quality aftermarket equivalent where one exists, and the price for each. We register both warranty layers in writing before any work begins.
- 4
We do the work. The old roof assembly comes out, the framing gets repaired or replaced as needed, the new unit goes in, and the flashing, sealant, and weather barrier get lapped correctly from top to bottom.
- 5
We test and clean up. We run water over the roof line, check the reveal from both sides of the door, and verify the slab opens and closes without binding. The work area is left clean.
- 6
We stand behind it. Every job carries the Done Right Promise. If something is not right, we make it right, no paperwork and no arguing.
What Therma-Tru Roof Replacement & Installation Costs in Wellington
Here are honest ranges for common Therma-Tru roof replacement scenarios in Wellington. These are line-item estimates, not final quotes; your opening size, framing condition, and product line will move the number.
- Single entry door roof assembly repair (Classic-Craft, Fiber-Classic, Smooth-Star): $1,200 to $2,600 depending on jamb and header condition
- Full roof assembly replacement for one door including new cap flashing: $1,800 to $3,400
- Patio door roof assembly replacement with sill pan and end dams: $2,200 to $4,200
- Double-door roof assembly with new engineered header: $2,800 to $4,800 including framing
- Rot repair and sistering of existing framing, per section: $400 to $900
What moves the price: the width of the opening, whether the header needs replacing, the condition of the wall sheathing behind the flashing, and whether we are reusing your existing slab or installing a new one. We quote everything on paper before work starts, and the price does not change once the job is underway. Call (561) 349-4826 for a free estimate, and we’ll come measure.
Why Wellington Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We have been serving Wellington, Lake Worth, Royal Palm Beach, and the rest of Palm Beach County since 2008, and we are not going anywhere. Dale Kessler started this company in 2008 on a simple rule: if the pane is not true, the job is not done. That applies to roof lines as much as window sashes.
We are an independent Therma-Tru service provider, which means we are not tied to one manufacturer’s line. If a PGT, CGI, CWS, or ES Windows product is the better fit for your opening, we will tell you that on paper, side by side with the Therma-Tru option. Every job is covered by the Done Right Promise and The Keystone Standard: both warranty layers registered in writing, durations stated, before the truck leaves the driveway. We’ll be there when we say.
FAQs
No, replacing a failed roof assembly with correct flashing and proper installation does not void the door slab warranty. We register both warranty layers in writing on every job, so if a manufacturer claim ever comes up, the paperwork is already in order. Call (561) 349-4826 and we’ll walk you through what your specific Therma-Tru product still carries.
If the framing behind the door is solid, repair is usually the right call and costs less. If the header has sagged, the jamb corners are soft, or water has reached the subfloor, replacement is the only fix that will last. We will show you the condition of the framing in person before you decide, not after we open the wall.
In Wellington’s climate, a properly installed Therma-Tru roof assembly lasts fifteen to twenty years before the flashing, sealant, or framing begins to show real wear. Doors that face north or northeast take the most weather and tend to fail first. We see units from the early 2000s reaching end of life right now and can tell you honestly whether yours has another five years or is already past saving.
We quote both on paper and let you choose. For structural components like the door slab itself, we recommend OEM Therma-Tru parts because the product line tolerances are matched. For flashing, sill pans, and some framing components, quality aftermarket materials can outperform the original in Florida’s weather, and we will tell you which we would put on our own home.
We keep common Therma-Tru roof assembly components in stock, and most jobs are scheduled within a week of the estimate. A live person answers the phone 24 hours a day at (561) 349-4826, so call and we will get you on the schedule.
