Therma-Tru Impact Windows in Royal Palm Beach: What to Know First
We install, replace, and service Therma-Tru impact windows throughout Royal Palm Beach as an independent Therma-Tru service provider. Most Therma-Tru impact window replacements in Royal Palm Beach run between $1,100 and $3,400 per opening depending on size, series, and glass package, and a typical full-opening replacement takes one day once the unit arrives. We are not the cheapest bid in Royal Palm Beach, and we don’t try to be. We quote manufacturer lines side by side on paper, register both warranty layers before the truck leaves, and stand behind the work in writing. If you own a Therma-Tru door or window and need impact-rated glass, call (386) 251-6745 for a free estimate.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a solid entry door, and the impact-rated lines have held up well in Palm Beach County. But after years of setting and sealing them across Royal Palm Beach, we’ve learned where they give. These are the five failures we see most often, and what we do about each one.
- Fiberglass skin delamination on Classic-Craft and Smooth-Star units. The fiberglass face starts to separate from the core, usually down near the threshold where standing water sits after a Royal Palm Beach afternoon downpour. The glass can still be sound while the frame lets water past the weatherstrip. We pull the unit, reset the frame on a sealed sill pan, and replace the glass with an impact-rated insulated unit that matches the original profile.
- Warped jambs on south-facing Therma-Tru entry systems. A dark-finished fiberglass door on a western or southern exposure in Royal Palm Beach sees surface temperatures above 140 degrees in August. Over ten or fifteen years, the jamb moves just enough that the impact glass no longer seats against the seal. We measure the rough opening, correct the framing, and set the new impact unit true before we seal it. If the pane is not true, the job is not done.
- Failed insulated glass seals on the Slim-Line and patio door lines. In Royal Palm Beach’s humidity, a seal failure shows up fast: fog between the panes after the first cold snap of January, or a white mineral haze that won’t wipe clean. On impact-rated units, you don’t just replace the sash. We order the correct impact-rated insulated glass unit (IGU) with the proper laminate interlayer, set it square, and rebalance the panel so it doesn’t drag.
- Broken or seized hinges on Therma-Tru hinged impact patio doors. The coastal air works on cheap hardware fast. A door that binds in July or won’t close without lifting is usually a hinge that’s worn out of round, not a door problem. We replace the hinges with stainless hardware rated for the full weight of the impact-rated panel, then rehang the door so the reveal is even top to bottom. A door that closes with two fingers is the standard.
- Improperly flashed transoms and sidelites around Therma-Tru entry assemblies. We see this on homes in the original Royal Palm Beach subdivisions where the builder set the transom directly onto the subfloor with no sill pan. Water wicks up behind the frame, the rough opening rots quietly, and the impact rating stops meaning much because the frame is no longer anchored to sound wood. We remove the assembly, rebuild the rough opening with pressure-treated stock, install a true sill pan with end dams, and reset the entire unit.
Our Therma-Tru Impact Windows Process
Every Therma-Tru impact job in Royal Palm Beach follows the same sequence. No shortcuts, no surprises.
- 1
Call and talk to a person. A live person answers (386) 251-6745, 24 hours a day. You tell us what you’re seeing. We schedule a time that works.
- 2
On-site measurement and diagnosis. Our technician measures every opening twice, checks the rough opening for rot and square, and notes the exact Therma-Tru series you have. Dale Kessler learned framing tolerances at Palm Beach State College and still checks them by habit on every job.
- 3
Parts decision on paper. For glass replacement, we quote OEM and quality aftermarket impact IGUs side by side with the real difference between them spelled out. No pressure. You decide with the numbers in front of you.
- 4
Installation. We set the unit on a sealed sill pan, shim it true, anchor it to the manufacturer’s spacing, and seal the exterior with the right grade of caulk for Florida UV and heat. The entire opening gets attention, not just the glass.
- 5
Test and register. We cycle the window or door, check the reveal, confirm the interlocks engage, and clean the glass. Before the truck leaves, we register both manufacturer warranty layers in your name and hand you the paperwork.
- 6
Done Right Promise. If something isn’t right in the first 90 days, we come back and make it right. No arguing, no fine print.
What Therma-Tru Impact Windows Costs in Royal Palm Beach
Royal Palm Beach pricing for Therma-Tru impact work breaks down like this, assuming a standard opening and no major framing repair:
- Impact glass replacement in an existing Therma-Tru frame: $650 to $1,400 per panel, depending on size and glass package.
- Full impact window replacement, standard sizes: $1,100 to $2,200 per opening.
- Therma-Tru entry door with impact glass, full replacement: $2,400 to $3,800, depending on series (Smooth-Star at the lower end, Classic-Craft with decorative glass at the top).
- Rough opening repair (rot, warped framing): $200 to $800 per opening, determined after we open the wall and see what’s actually there.
What moves the price: opening size, the series you’re matching, whether the frame itself is salvageable, and whether we’re pulling permits on a structural change. We give fixed pricing in writing before work starts, and the bill matches the quote. Call (386) 251-6745 for an exact number. Estimates are free.

FAQs
Replacing the glass on a Therma-Tru door generally does not void the door’s structural warranty, but the work must be done correctly with a properly sized impact-rated IGU, and the door must be rehung so it closes and seals properly. We document the glass spec, the install, and the alignment so you’re covered if anything is ever questioned. Call (386) 251-6745 and we’ll walk you through what your specific series requires.
If the frame is sound and the seal has failed, glass replacement usually makes sense and costs less than half of a full door replacement. If the frame is warped, delaminated, or the rough opening has rot, replacement is the honest call. We’ll show you the condition of the framing with the numbers in front of you. Call (386) 251-6745 for a straight answer and a free estimate.
Standard impact glass replacements are usually completed in one visit once the correct IGU arrives, which is typically one to three weeks depending on the series. Full door or window replacements take a day on site. We’ll give you a real timeline when we quote, and we’ll be there when we say. Call (386) 251-6745 to schedule the measurement.
Yes. We work with the original Therma-Tru series, so the new impact glass and any replaced components match the profile and finish of the rest of your opening. For full replacements, we spec a unit that fits the existing rough opening and matches the look of your home. Call (386) 251-6745 and we’ll take the measurements to confirm.
No. We quote fixed pricing in writing, and the bill matches the quote. The only exception is if we find hidden rot or framing damage that couldn’t be seen before the wall was opened, and in that case we stop, show you what’s there, and give you the number before any additional work happens. That’s a square deal. Call (386) 251-6745 for your free estimate.
