Fast, Reliable Window Installation Across Sebastian
Window installation in Sebastian comes down to two things most of the time: corrosion from the inlet air, and jalousie windows that won’t pass code anymore. Most homes in Sebastian Highlands were built between the mid-1970s and early 1990s, and thousands of them still have the original single-pane aluminum frames and louvered glass the builders put in. Those windows worked when the houses were new. They don’t work now. The salt air off the Indian River Lagoon and Sebastian Inlet eats aluminum faster here than almost anywhere else in Indian River County, and the frames we pull out of Sebastian Highlands homes are often so pitted that the screws have nothing left to bite into. Dale Kessler founded TruePane Windows & Doors to fix exactly this kind of work properly, and we’ve been doing it long enough to know what’s behind the wall before we open it. Call (772) 218-5890 for a free estimate, and we’ll send someone who actually knows Sebastian.
Why TruePane Windows & Doors Is Sebastian’s Preferred Window Installation Company
We’re not the cheapest window installers in Sebastian, and we don’t try to be. What we are is thorough. Every TruePane crew that works in Sebastian has opened up enough CBS homes in Sebastian Highlands to know what an original 1980s aluminum frame looks like after thirty-five years of inlet air. That matters because the bid you get from a company that doesn’t know the area is going to miss the reframing, the header work, and the code upgrades the permit will trigger. Then the price moves. Ours doesn’t.
We’ve been at this since 2008 under Dale Kessler, a second-generation glazier who built the company on a rule that’s still on the whiteboard: if the pane is not true, the job is not done. Our window installers are background-checked, uniformed, and trained to measure every opening twice before ordering anything. Every job carries the Done Right Promise. Both manufacturer warranty layers get registered in writing, with durations stated, before the truck leaves your driveway. That’s The Keystone Standard, and we don’t skip it.
Local homeowners also get a live person on the phone 24 hours a day, seven days a week. Not a voicemail tree. Not a regional call center. You call, someone answers, and we schedule for Sebastian with real lead times, not a promise we can’t keep. If you’ve been through contractors who vanish after the check clears, you’ll notice the difference on the first call.
Our Window Installation Services in Sebastian
Casement Windows
Casement windows are the workhorse replacement for the jalousie panels that dominate Sebastian Highlands. They seal tight against wind-driven rain, they crank open for full ventilation, and they meet Indian River County’s 130 mph design wind speed requirements when ordered impact-rated. We quote casements side by side on paper from manufacturers like Pella and Marvin, so you see exactly what you’re paying for before you commit. For an older Sebastian home, a casement swap is usually the cleanest fix when a jalousie unit has to come out.
Impact-Rated Sliding Windows
Sliding windows fit the horizontal openings in a lot of Sebastian’s CBS ranch homes, but they need to be impact-rated now. The old aluminum sliders from the 1980s were not built for the wind load Indian River County enforces today, and the salt air has usually pitted the tracks beyond repair. We install fusion-welded impact sliders with low-E glass that handle the corrosion and the storm season. Last month we opened up a 1983 CBS home on Periwinkle Drive in Sebastian Highlands for a sliding-window swap and found the original aluminum frame so pitted from inlet air that the jamb screws had no bite left. We reframed the rough opening before installing the new unit. That’s the kind of thing a generic quote never accounts for.
Fixed & Picture Windows
Fixed windows give you the lagoon view without the frame failure. For Sebastian homes facing the water or sitting within a few miles of Sebastian Inlet, a fixed picture window is the most corrosion-resistant option there is, since it has no moving hardware to seize up. We install fixed windows from Milgard and Marvin, and on Sebastian Highlands homes we always inspect the surrounding frame for salt damage before ordering glass, because the opening usually needs work even if the old window still looks fine from inside.
Single & Double Hung
Double hung windows are common in the older wood-frame homes scattered around Sebastian outside the Highlands subdivision, and they’re still a solid choice for replacement work. We install single and double hung units that meet Florida Product Approval standards, and we register both warranty layers in writing on every install. If your home has original single hung aluminum frames, the spring balances and jamb liners are probably shot from salt exposure, and a new window is the only durable fix.

Common Window Installation Problems We See in Sebastian Homes
- Salt-air pitting on original aluminum frames. The double salt-air corridor between the Indian River Lagoon and Sebastian Inlet corrodes aluminum jamb and sash surfaces fast. We regularly find frames in Sebastian Highlands so pitted that new windows cannot be anchored until the rough opening is reframed.
- Jalousie windows that can’t pass code. Those louvered glass panels were standard in 1970s Florida construction, and Sebastian Highlands still has thousands of them. They cannot be made hurricane-compliant under any retrofit scenario, and any permitted project that exposes them triggers mandatory full replacement, not a repair.
- Outdated wiring and undersized framing behind old window openings. CBS homes from the late 1970s and 1980s were built to older standards. Once we open the wall around a window in Sebastian, we sometimes find wiring that needs to be brought up to current code and headers that need reinforcement before the new window can be set.
- Failed seals and fogged glass from moisture and salt exposure. Inlet air carries moisture and salt that breaks down insulated glass seals faster than you’d see inland. A fogged double-pane unit in Sebastian often needs full sash replacement, and it’s usually a sign the frame is not far behind.

FAQs - Window Installation in Sebastian
Why do window installers in Sebastian Highlands say my jalousie windows have to go, even if I’m only replacing one other window?
Because jalousie windows cannot meet current Florida Building Code wind-load or impact standards, and any permitted project that exposes them triggers mandatory full replacement. Sebastian Highlands homes built in the 1970s and 1980s are full of these louvered panels, and local inspectors flag them immediately once a permit is pulled for adjacent work. You don’t have to replace every jalousie in the house, but you do have to replace the ones touched by the permitted scope. Call (772) 218-5890 and we’ll explain exactly what your project will trigger.
How bad is the salt-air corrosion really on aluminum windows near Sebastian Inlet?
Bad enough that we’ve pulled original aluminum frames out of Sebastian Highlands homes that had no jamb screw bite left at all. The inlet creates an accelerated salt-spray corridor that pushes marine air deeper into the neighborhood grid than typical coastal exposure, and aluminum frames pit and corrode from the inside out. By the time you see the pitting on the outside, the jamb is usually compromised. That’s why we inspect every opening before quoting, and why we include reframing in the bid when we know it’s coming.
My older Sebastian home has original single-pane aluminum windows. Can I just replace the glass to meet code?
No. Single-pane aluminum frames cannot be retrofit to meet current Florida Building Code wind-load requirements, and the frames themselves are usually too corroded to save anyway. Glass replacement without frame replacement doesn’t address the structural or impact deficiencies, and it won’t pass a Sebastian permit inspection. The fix is full window replacement with Florida Product Approval impact-rated units. Call (772) 218-5890 for a free estimate that covers the whole scope.
Does your window installation quote for Sebastian Highlands include the code upgrades a permit will trigger?
Yes. Our quotes include the permit work, the reframing, the header reinforcement, and any wiring corrections we can anticipate based on the home’s age and construction. We’ve done enough Sebastian Highlands homes to know what a 1980s CBS opening usually needs once the wall is open. If we find something genuinely unexpected, we price it in writing and get your approval before we touch it. No change orders you didn’t sign off on. That’s how TruePane has always worked under Dale Kessler.
What does an ENERGY STAR rated impact window actually save on my electric bill in Sebastian’s climate?
A full replacement from single-pane aluminum to ENERGY STAR rated impact glass typically cuts the cooling portion of your electric bill by 15 to 25 percent in Sebastian’s climate, depending on the home’s orientation and existing insulation. The bigger savings come from not running the AC as hard against the heat absorbed by old aluminum frames and single-pane glass. Low-E coatings also block the UV that fades furniture and flooring near windows. For an exact number on your home, call (772) 218-5890 and we’ll walk the house and give you a straight answer.
