AfterTherma-Tru Window Installation in Royal Palm Beach: What to Know First
Therma-Tru window installation in Royal Palm Beach runs between $85 and $275 per window for labor on a standard retrofit, depending on the frame condition and whether we are working with original Therma-Tru hardware or replacing it. Most single-window jobs wrap up in one visit; a full house of eight to twelve Therma-Tru windows typically takes two to three working days. We are an independent Therma-Tru service provider, not a factory-authorized installer, which means we quote the work honestly and register the warranty layers that actually apply.
This page is written for Royal Palm Beach homeowners who bought Therma-Tru windows years ago, live with them daily, and now need someone who understands how they fail in this climate. If you have a Therma-Tru window that will not lock square, a sash that drags, or a frame that has started to pull away from the stucco, call (386) 251-6745. A live person answers.
How Therma-Tru Products Fail - and How We Fix Them
- Fogged glass in Therma-Tru SlimLine double hungs. The SlimLine series used a thinner insulated glass unit, and after ten to fifteen years of South Florida humidity cycles, the perimeter seal lets go. We see it most often on west-facing elevations in the Madison Green and La Mancha neighborhoods, where afternoon sun beats on the glass. The fix is a new insulated unit set to the exact frame depth, not a silicone smear over the old seal.
- Dragging sashes on Therma-Tru casement windows. The original steel hinge hardware on older Therma-Tru casements corrodes in this coastal air, and the sash starts to hang low on the hinge side. Homeowners usually notice the crank getting harder to turn before they notice the gap at the top corner. We replace the hardware with a marine-grade aftermarket hinge that matches the original screw pattern, and we shim the sash so it closes against the weatherstripping instead of fighting it.
- Failed balance systems in Therma-Tru single hungs. The block-and-tackle balances Therma-Tru used on certain production runs lose tension unevenly. One side lets go before the other, and the window drops hard or refuses to stay open. We carry replacement balances sized to the exact sash weight, and we set both sides together so the window lifts with even pressure.
- Weeping system clogs on Therma-Tru horizontal rollers. Every sliding window has weep holes at the bottom track to drain water. In Royal Palm Beach, oak pollen and fine sand pack those channels solid within a few seasons, and the track starts holding water after every rain. We clean the tracks, clear the weeps, and check the interior drain slope so water exits instead of pooling against the frame.
- Frame-to-stucco separation on Therma-Tru picture windows. Fixed windows take the full brunt of wind load, and the original caulk line between the Therma-Tru frame and the stucco breaks down under UV exposure within five to seven years. The window itself is usually fine. We remove the old caulk, backer-rod the gap, and reseal with a stucco-grade sealant that flexes with the wall.
Our Therma-Tru Window Installation Process
- 1
Call and describe the window. You tell us what the Therma-Tru window is doing, or not doing. We ask the questions that matter: how old the install is, which direction it faces, whether it leaks when the rain comes sideways.
- 2
In-home measure and quote. We send a background-checked, uniformed technician to look at the window in place. Every opening gets measured twice, and we write the quote on paper, side by side with the options, before any work is authorized.
- 3
Parts and frame decision. We match OEM where it matters most: glass thickness, frame depth, mounting points. Where an aftermarket part is the stronger choice for South Florida, we say so and tell you why. No change orders hidden in the fine print.
- 4
The install. We pull the old sash or unit, inspect the rough opening, correct any framing tolerance issues, and set the new window square, level, and plumb. Shims are set, not stacked, and every screw lands on a stud or solid blocking.
- 5
Seal, test, and walk-through. The window gets sealed inside and out, operated through its full range, and checked for air movement around the frame. We show you the work before we clean up, and both warranty layers are registered in writing before the truck leaves the driveway.
What Therma-Tru Window Installation Costs in Royal Palm Beach
Costs depend on the window style, the frame condition, and whether we are repairing or replacing. What we quote is what you pay: upfront pricing, no surprise line items.
- Balance or hardware replacement on a single Therma-Tru double hung: $85-$160 per window
- Insulated glass replacement on a Therma-Tru SlimLine or casement: $140-$260 per sash
- Full frame retrofit of a standard Therma-Tru double hung: $190-$275 per window, depending on size and stucco work
- Full-house Therma-Tru window install (8-12 windows): most Royal Palm Beach jobs land between $2,200 and $3,800
What moves the price is access, frame rot behind the stucco, and whether the original window used a custom size. If you want an exact number for your windows, call (386) 251-6745 and ask for a free estimate. We will write it down for you, and it will match the invoice.

FAQs
Yes, we replace insulated glass units in most Therma-Tru frames. If the frame is square, the seal is the failure point, and the operating hardware is sound, a glass replacement is usually the right call and costs a fraction of a full window. If the frame has pulled from the stucco or the sash is twisted, we will tell you before quoting either path.
No. We are an independent Therma-Tru service provider, and we do nothing that would void a manufacturer warranty. We follow Therma-Tru’s installation tolerances and use parts that meet or exceed the original specs. Our Keystone Standard means both applicable warranty layers are registered in writing before we leave the driveway. Call (386) 251-6745 and we will walk you through exactly what is covered on your specific windows.
We schedule most Therma-Tru window installs within a few business days, and a live person answers the phone around the clock to get you on the schedule. If the window is a security risk or the rain is getting in, we will prioritize it. Call (386) 251-6745 and tell us what is happening.
It depends on the window and the frame. In Royal Palm Beach, we see Therma-Tru frames lasting well past twenty years when they were installed correctly and sealed against water. If the frame is sound and the issue is glass, hardware, or seals, repair is almost always the less expensive and faster option. If the frame itself is failing, replacement is the honest answer. We will show you the numbers for both and let you decide.
