Therma-Tru Door Installation in Greenacres: What to Know First
Therma-Tru door installation in Greenacres typically runs $350 to $900 for a standard entry door swap, with most jobs completed in a single visit by a two-person crew. We are an independent Therma-Tru service provider, not a manufacturer-authorized dealer, which means we make parts and warranty decisions based on what actually holds up in South Florida humidity, not on what a corporate program tells us to sell. If you own a Therma-Tru door that is binding, sagging, or leaking air around the frame, call (754) 339-0784 for a free estimate.
This page is for Greenacres homeowners who already own a Therma-Tru door, or who are considering one, and want installation done by people who understand how these doors behave in our climate. Dale Kessler grew up off Jog Road, and the first thing he’ll tell you about Therma-Tru is that the door slab itself is rarely the problem. The installation is.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds fiberglass and steel door slabs that hold up well against heat and moisture. What fails in Greenacres is usually the interface: the frame, the weatherstripping, the threshold, the sill pan, and the way the unit was set in the rough opening. Here is what we see on Therma-Tru doors in this area, and what we do about it.
- Smooth-Star frame rot at the sill corners. The Smooth-Star series is common in Greenacres homes built in the 1990s and 2000s. The door slab is fiberglass, but the frame on older units was finger-jointed pine. When the sill pan was never installed, or was installed flat instead of sloped, water wicks into the bottom corners. The door starts sticking on the latch side in July. We replace the rotted frame section, set a proper sloped sill pan, and rehang the existing slab if it is still true.
- Classic-Craft weatherstrip compression failure. Classic-Craft doors use a compression weatherstrip system that works well until someone adjusts the threshold too high to compensate for a sagging hinge. The weatherstrip crushes permanently, air leaks around the top and latch side, and the homeowner cranks the A/C harder. We re-shim the hinges to restore the correct reveal, then replace the weatherstrip with the OEM profile or a higher-durometer aftermarket match. The fix is in the reveal, not in cranking the threshold.
- Fiber-Classic slab delamination from storm-driven rain. On east-facing Greenacres entries without a storm door, wind-driven rain beats directly against the slab. Fiber-Classic slabs have a fiberglass skin over a polyurethane core. If the bottom rail seal was ever broken by a kicked-in threshold or a pet door install, water gets inside and the skin starts to bubble. Once delamination starts, the slab cannot be saved. We quote the replacement honestly and install the new unit with a full sill pan and a properly lapped drip cap.
- Adjustable threshold bind on Tru-Defense impact doors. Therma-Tru’s impact-rated lines, including Tru-Defense, ship with an adjustable threshold. In Greenacres, where the ground shifts between wet and dry season, homeowners sometimes adjust the threshold themselves and over-tighten it. The door scrapes, the sweep tears, and water channels under. We set the threshold to the correct height for the slab reveal, verify the sweep compression, and lock it in place.
- Hinge screw pullout on heavier glass units. Therma-Tru doors with full glass lites, or double doors like the Classic-Craft French units, put real weight on the hinge screws. The factory ships 3-inch screws that thread into the wood frame stile. Over years of heat cycling, the screws work loose and strip. We remove the stripped screws, inject a two-part wood hardener into the stile, and reset with longer, larger-gauge fasteners. The door hangs true again without a wedge under the corner.
Our Therma-Tru Door Installation Process
Every Therma-Tru job we do in Greenacres follows the same sequence. Nothing gets skipped, and nothing gets billed as an extra that should have been included.
- 1
Call and schedule. A live person answers, not a menu. We ask what the door is doing, what brand and model you can see on the hinge stamp, and when you want us there. We’ll be there when we say.
- 2
Inspection and measurement. The technician measures the slab, the rough opening, the reveal on all three sides, and checks the sill for level. We measure twice. Dale’s rule is simple: if it is not right in the opening, it will not be right in ten years.
- 3
Parts and frame decision. We show you the options on paper: OEM Therma-Tru parts where the warranty matters, quality aftermarket parts where the OEM part is the known weak point. You decide with the numbers in front of you.
- 4
Installation. Old frame comes out clean. Sill pan goes in sloped. New or existing slab is set, shimmed, and squared. Weatherstripping is replaced. Hardware is adjusted. We do not reuse stripped screws or bent hinges.
- 5
Test and stand behind it. The door is opened and closed under pressure, sprayed for leaks, and the sweep is checked. Both warranty layers are registered in writing before the truck leaves the driveway. The Done Right Promise applies to every Therma-Tru install we do.
What Therma-Tru Door Installation Costs in Greenacres
Door installation pricing in Greenacres depends on what we find when the old unit comes out. Here are the ranges we quote most often:
- Standard entry door slab swap, frame intact: $350 to $550. Includes shimming, weatherstrip, hardware adjustment, and threshold set.
- Full frame replacement with new Therma-Tru or comparable slab: $800 to $1,400. Includes sill pan, drip cap, exterior trim, and disposal of the old unit.
- Impact-rated Therma-Tru or equivalent installation: $1,200 to $2,200. Includes the heavier slab, reinforced frame anchoring, and the inspection paperwork.
- Double door or French door rehang and alignment: $450 to $900. Includes hinge repair, astragal adjustment, and weatherseal replacement.
What moves the price is rot. If the subfloor or the rough opening framing is soft, that gets repaired before the new unit goes in. We quote it on paper, before we start, with no change orders on the back end. Call (754) 339-0784 for an exact quote. The estimate is free.

We have been setting doors in Palm Beach County since 2008, and Dale Kessler founded TruePane Windows & Doors in 2008 on a simple standard: if the pane is not true, the job is not done.

We register both warranty layers in writing before the truck leaves, and if something is not right in 90 days, we come back and make it right. No paperwork fight, no fine print. We also service PGT, CGI, CWS, and ES Windows, so if your Greenacres home has a mix of impact products from different manufacturers, one crew can handle all of it.
FAQs
Yes. We install homeowner-supplied Therma-Tru doors in Greenacres regularly, provided the unit is the correct size for the existing rough opening. We inspect the new unit before we touch the opening, and if the slab or frame has shipping damage or a manufacturing defect, we tell you before we cut anything.
No. Therma-Tru slab warranties are tied to the product, not to a specific installer. What voids warranties is improper installation: missing sill pans, unshimmed frames, hinges that are not fully fastened. We install to manufacturer spec specifically because we want that warranty to hold if you ever need to file a claim. Call (754) 339-0784 to schedule a free estimate.
Yes. For minor repairs, we source matching Therma-Tru parts when they are available. For full replacements, we can match the style and panel profile closely with a Therma-Tru slab or a comparable fiberglass unit from one of our other manufacturer lines. We quote the options side by side on paper so you see exactly what you are paying for.
Yes. We install impact-rated Therma-Tru and equivalent units, and we know the Greenacres and Palm Beach County code requirements for opening protection on doors. The installation includes the proper frame anchoring, the inspection paperwork, and a final check that the unit passes the first time. Call (754) 339-0784 for a free estimate on an impact door.
A standard single entry door swap takes one visit, usually four to six hours. A full frame replacement with rot repair takes one day, sometimes two if the rough opening needs structural work. We will tell you before we start, in writing, and we will be there when we say.
