Therma-Tru Window Installation: The Oakland Park Owner’s Guide
If you have a Therma-Tru window that needs installation or replacement in Oakland Park, we stock the parts, match them to your model, and handle the full install. Most Therma-Tru window installations in Oakland Park run between $220 and $680 per window depending on the unit size and what failed. We can usually get it done same day or next day, and every job leaves with both warranty layers registered in writing.
Most Oakland Park homeowners find us the way you probably found this page: a window is fogged between the panes, or a sash won’t stay up, or the weather stripping has gone hard and the humidity is getting in. The install was fine for fifteen years. Then one day it wasn’t.
Which Therma-Tru Models This Applies To
Therma-Tru is known more for entry doors than windows, and that’s where Oakland Park owners get tripped up. Many homes built in the 1990s and early 2000s around Oakland Park have Therma-Tru doors with sidelight windows or transom windows, and those are the units we most often reinstall. The sidelights flanking a Therma-Tru front door fail faster than the door itself: the seal breaks, condensation collects, and the frame starts to swell in our wet season.
Identifying your unit is straightforward. Therma-Tru stamps a manufacturing code on the spacer bar between the glass panes, usually on the bottom edge of the sidelight or transom. If that code is gone, measure the visible glass, not the frame. The frame dimensions are what the original installer used; the glass unit itself runs square and true to the opening. We match OEM glass when the original is still in good structural shape and quality aftermarket equivalents when the original has failed early, which we see often enough in Oakland Park’s salt air and afternoon thunderstorms. We are an independent installer, not affiliated with Therma-Tru, but we know their spec sheets and warranty language better than most.
Signs Your Therma-Tru Window Installation Is Failing
- Fog between the panes. You’re looking at a seal failure. Oakland Park’s humidity works on the seal year-round, and once moisture is inside the unit, no amount of wiping the outside glass helps. The unit needs replacement.
- Water staining on the interior sill or wall below. This usually means the flashing was never lapped correctly, or it has corroded over time. We see this on east-facing walls where the morning storms hit first.
- Drafts you can feel with the window closed. Weather stripping on Therma-Tru sidelights hardens and loses its memory. You can feel the air moving before you can see any damage.
- The sash sticks or drops when you open it. On operable Therma-Tru units the balance system wears out. This happens faster in salt air; the metal components corrode inside the track.
- Visible gap between the frame and the rough opening. Sometimes the original install in Oakland Park was “good enough.” The window still looks fine from the street, but the caulk line has separated and daylight shows through. That means water is getting in somewhere.
Replacement Cost & What’s Included
A Therma-Tru window installation in Oakland Park typically runs $220 to $680 per window, including the part and the labor. Sidelights fall on the lower end when the frame is intact and we’re replacing the insulated glass unit only. Transoms and larger units run higher, especially if the frame has water damage and needs rebuilding.
Every quote we give in Oakland Park is line-item priced on paper. You see the part cost, the labor, and any materials for sealing and flashing, separately. If the frame is sound and it’s a straight glass replacement, you won’t see surprise charges later. If we open the wall and find rot, we stop and show you before we proceed. The Done Right Promise covers the workmanship, and The Keystone Standard means your Therma-Tru manufacturer warranty and our workmanship warranty are both registered in writing before we leave the driveway.
DIY or Call Us?
You can check the stamp on the spacer bar, note the glass dimensions, and take photos of the fogging or water staining. Those photos help us quote more accurately. What we don’t recommend is removing a Therma-Tru window unit yourself. Sidelight glass is tempered and heavy. If it’s a unit next to an entry door, the frame carries load from the door assembly, and pulling the glass without properly bracing the frame can shift the entire door opening. We’ve corrected enough DIY removals in Oakland Park to know that the money saved on labor rarely covers the cost of fixing a twisted frame.

FAQs
In Oakland Park’s heat and salt air, a properly installed Therma-Tru window unit should hold its seal for 15 to 20 years before you see fogging or seal failure. Units installed against an east-facing wall or without proper flashing tend to fail in 8 to 12 years. Call (863) 264-3649 if yours is going hazy and we’ll tell you exactly what failed.
No. Once moisture is between the panes, the insulated glass unit is compromised and cannot be repaired; the unit gets replaced, not regassed. The good news is the replacement often costs less than people expect, especially when the frame is still sound. Call us for an exact quote on your unit.
A standard Therma-Tru sidelight or transom replacement in Oakland Park takes one to two hours once we’re on site. If the frame needs rebuilding, the job can run half a day. We bring the replacement glass, sealants, and flashing on the truck, so most jobs finish in one visit.
We stock common insulated glass units for Therma-Tru sidelights and transoms and can source OEM or quality aftermarket units for less common sizes within a few days. We also carry replacement weather stripping and balance hardware. If we need to order, you’ll know before we leave the first visit.
