AfterTherma-Tru Roof Replacement & Installation in Naples: What to Know First
Therma-Tru roof replacement and installation in Naples runs $850-$2,400 for most residential jobs, with full door-and-frame replacements on the higher end. We complete the majority of Therma-Tru work in one visit, and every job is backed by both warranty layers registered in writing before the truck leaves your driveway. If you own a Therma-Tru door that has started binding, leaking, or letting daylight through the frame, call us at (239) 326-9942 for a free estimate.
This page is for Naples homeowners who bought Therma-Tru doors years ago and intend to keep them, not swap them out for something different when the first problem shows up. We are an independent Therma-Tru service provider, not a factory-authorized dealer. That means we report what we find, not what a brand rep would prefer you hear.
How Therma-Tru Products Fail - and How We Fix Them
Here is what we actually see on Therma-Tru doors in Naples, based on years of pulling them apart and setting them right:
- Sill rot on Classic-Craft and Smooth-Star entry doors. Therma-Tru fiberglass doors hold up well, but the composite sills soak water when the weep holes clog with salt crust and fine sand. In East Naples and off Bayshore Drive, we regularly find sills soft enough to flex under foot. The factory pours a sill pan that drains poorly once the exterior grade settles. We pull the door, re-flash the rough opening, replace the sill, and reset the slab so the sweep seals evenly.
- Warped frames from direct western exposure. The fiberglass slabs on Classic-Craft and Pulse lines resist warping, but the pre-hung frames are finger-jointed pine and they do not. Homes along Gulf Shore Boulevard catch the afternoon sun and salt air together, and we see frames twist a quarter inch in a single season. A twisted frame makes the slab bind at the top corner and drag at the bottom. We square the rough opening with trim shims, not caulk, because caulk cannot hold a frame that is fighting the house.
- Failed weatherstripping on all lines after 6-8 years near the water. Therma-Tru ships doors with compression weatherstripping that hardens fast in salt air. The strips still look whole, but they lose their memory and let hot air in around the latch stile. We replace the factory stripping with a denser aftermarket seal rated for coastal exposure. This costs less than $60 in materials and drops the cooling bill more than most people expect.
- Broken sill caps on decorative glass doors. The Therma-Tru lines with decorative glass inserts, like the Classic-Craft Mahogany Collection, put a false sill cap over a fiberglass base. The cap is fiberglass too, but thinner, and a hard knock from a grocery cart or a ladder cracks it. Owners often think they need a whole new door. They do not. We order the exact sill cap from Therma-Tru’s parts network and replace it in under an hour.
- Hinge-side seal failure behind the brickmould. This one is invisible until the door is off. The factory caulks the brickmould to the frame at the plant, but that bead dries and separates within a few years in Naples humidity. Water wicks into the gap and rots the jamb from the outside in. We pull the brickmould, clean the joint, re-caulk with marine-grade sealant, and in most cases save the frame before the rot reaches the structural opening.
Our Therma-Tru Roof Replacement & Installation Process
- 1
You call. A live person answers at (239) 326-9942, day or night. We ask what the door is doing and schedule a free estimate at a time that works for you.
- 2
We inspect the full opening. A uniformed technician measures the rough opening twice, not once. We check the sill, the jamb reveals, the header, and whether the slab is square. Half the time the problem is the opening, not the door.
- 3
We quote on paper. You get a written line-item quote showing OEM Therma-Tru parts versus quality aftermarket options side by side. No surprises later, because the price is in your hand before the work starts.
- 4
We order the right parts. If the door needs new hinges, a stop, or a sill cap, we order from Therma-Tru’s parts network when it matters. When a generic part genuinely performs better in coastal conditions, we say so and quote accordingly.
- 5
We remove, repair, and reset. The old frame comes out carefully. The rough opening is stripped to bare framing and checked for rot. New flashing goes in before the frame. The slab is shimmed square, not forced square, because forcing it now means binding in July.
- 6
We test and we register. The door opens, closes, and seals right before we leave. Both warranty layers are registered in writing on the spot. If it is not right when we leave, we come back until it is.
What Therma-Tru Roof Replacement & Installation Costs in Naples
Here are honest ranges for the Therma-Tru work we do most in Naples:
- Weatherstripping replacement: $85-$160
- Sill cap replacement: $120-$240
- Frame shimming and realignment: $250-$450
- Sill replacement with full re-flash: $500-$850
- Complete door and frame replacement: $1,200-$2,400 depending on slab style and glass package
The cost moves with three things: whether the frame is salvageable, whether you need OEM Therma-Tru parts or can run a quality aftermarket equivalent, and how much rot the opening reveals once the frame is out. Call (239) 326-9942 and we will quote you exact numbers in writing, with no change order waiting on the back end.

Most jobs finish in one visit. A live person answers the phone around the clock. We stand behind it.
FAQs
No. Using OEM Therma-Tru parts or verified aftermarket equivalents does not void your Therma-Tru warranty, and we register both warranty layers in writing before the job closes. The mistake that voids warranties is shoddy installation, not honest parts, which is why we measure twice and shim square, never force. Call (239) 326-9942 for a free estimate if you want the whole picture on paper.
Most Therma-Tru roof replacement and installation calls in Naples are single-visit jobs when the parts are on the truck or stocked locally. Weatherstripping, sill caps, and realignment are often done in under two hours. Full frame replacement takes longer if we have to order a slab. Call (239) 326-9942 and the person who answers will tell you what to expect, not a callback form.
If the slab itself is cracked or the frame is rotted into the structural opening, replacement is the honest call. If the door is binding, leaking air, or the sill flexes, repair is usually enough and costs far less. We will show you what we find and quote both paths if it is close, so you decide with facts, not pressure. Call (239) 326-9942 to schedule a free estimate.
With proper sealing and a straight frame, a Therma-Tru fiberglass slab can go twenty years or more in Naples, but the seals and sills will need attention every six to eight years in the salt air. Our work includes re-flashing and marine-grade caulk, which buys more time between visits. Call (239) 326-9942 and we will inspect the whole opening, not just the door.
