Fast, Reliable Window Replacement Across South Apopka
Most window replacement jobs in South Apopka run between $850 and $2,400 per opening for impact-rated units, and full frame replacements in the older CBS block homes typically land at the higher end because the rough opening usually needs masonry work before a new frame can be anchored. We’re TruePane Windows & Doors, and we’ve worked on enough South Apopka homes to know exactly what hides behind those original jalousie windows. If you’re tired of fogged glass, sticking tracks, or the draft that moves your curtains in August, call (813) 320-9346 and we’ll measure it, quote it in writing, and tell you straight what the job needs. No guessing. No markup on top of markup.
Why TruePane Windows & Doors Is South Apopka’s Preferred Window Replacement Company
We’re not the cheapest bid you’ll get in South Apopka. We don’t chase that. We build our reputation on doing the job once, correctly, and standing behind it in writing. Dale Kessler founded this company in 2008 because he was tired of watching manufacturers void warranties over sloppy installs and homeowners eat the cost. So we built a process that makes the warranty stick. That means both manufacturer warranty layers get registered before our truck leaves your driveway, and every install is covered by our Done Right Promise. If it’s not right, we make it right. No paperwork fights. No arguing.
Our crews know the specific problems South Apopka homes throw at them. The original jalousie bucks in these 1950s to 1970s concrete block houses were often set straight against raw block with no flashing and no sealant. Pull that old aluminum frame and you frequently find crumbling mortar and moisture-wicked block behind it. Most window companies don’t want that job. We plan for it. We quote for it up front. And when we say the price is fixed, we mean the number on the paper is the number you pay, even when we find more block damage than expected. That’s the difference between a crew that patches and prays and a crew that rebuilds the opening so the new window actually seals.
Our Window Replacement team works across South Apopka from a dispatch office in Miami, but the technicians who show up at your door are background-checked and uniformed, and they work like they’re installing glass in their own mother’s house. A live person answers our phone 24 hours a day. You call, you get a person. Not a voicemail tree.
Our Window Replacement Services in South Apopka
Full Frame Replacement
For the older CBS homes in South Apopka, full frame replacement is usually the right call. The original jalousie or louvered aluminum units are rarely worth saving, and the rough opening behind them often needs masonry patching before any modern window can go in. We pull the old frame, assess the block, patch what’s crumbling, then anchor a properly flashed, custom-sized frame built for Florida’s wind codes. This is the job that finally closes the gap between your window and your wall.

Insert Window Replacement
Insert windows make sense when the existing frame is still square and structurally sound. In South Apopka, that’s more common in homes that had a partial update in the 1990s or early 2000s. We measure every opening twice, custom-order the insert to fit the existing buck, and set it with shims and sealant so it performs. If the frame is rotted or the mortar behind it is failing, we’ll tell you straight and recommend full frame instead. We don’t put a good window into a bad opening.

Storm Window Replacement
South Apopka sits low and close to Lake Apopka, which means sustained humidity and summer storm water that finds its way into any unsealed gap. Storm window replacement over original single-pane units helps, but for most homeowners the better investment is an impact-rated replacement window that does the storm protection job permanently. We quote both options side by side on paper so you see exactly what you’re buying and what each one costs. No pressure. Just numbers.

Energy-Efficient Upgrade
Those original jalousie windows in South Apopka carry zero Florida Building Code wind-load ratings, and they bleed conditioned air year round. An energy-efficient upgrade doesn’t just cut your FPL bill. It also stops the fog, the drafts, and the humidity that rots interior trim and feeds mold along the sill. We install low-E, argon-filled glass packages rated for Florida’s climate, and we register every energy-efficiency warranty in writing before we leave.

Trusted Brands We Service in South Apopka
We’re an authorized installer for more than a dozen manufacturer lines, including. That matters more in South Apopka than it does in a big suburban subdivision, because the homes here need custom sizing, not off-the-shelf stock windows. Depending on your opening dimensions and wind-load requirements, we pull quotes from the manufacturer lines that actually make sense for your job and present them side by side on paper. You see the brand, the spec, the warranty duration, and the price. Then you decide. We don’t steer you toward the brand with the best spiff for us. We steer you toward the window that fits your block home and your budget.
Common Window Replacement Problems We See in South Apopka Homes
- Fogged glass from seal failure in original single-pane jalousies. The persistent lake humidity in South Apopka accelerates seal breakdown, and once the seal fails, the only fix is replacement. That fog isn’t just cosmetic. It means the insulating gas is gone and the window isn’t performing.
- Unflashed rough openings where old aluminum bucks sat directly against raw block. Wind-driven rain wicks straight into the masonry, and by the time you see water staining on the interior drywall, the block behind the frame has been wet for years. We patch and flash before we set the new frame.
- Narrow, non-standard rough openings sized for jalousie or thin aluminum sliders. A stock replacement window will not fit these openings properly. The lazy fix is to caulk the gap and call it done. The correct fix is custom sizing with proper shims and a sealed, flashed jamb.
- Moisture-damaged block and crumbling mortar behind original frames. On a 1962 CBS ranch near Lake Apopka, our crew pulled an original louvered aluminum unit to find the mortar at the rough opening had turned to powder and the block was spongy with trapped moisture. We patched the block, re-framed the opening for a custom-sized Marvin impact-rated casement, and flashed the new jamb with butyl tape before resetting the interior trim. That’s what sealing out South Apopka’s humidity actually looks like.

FAQs - Window Replacement in South Apopka
Because the original jalousie window bucks in these homes were set directly against raw concrete block with no flashing and no sealant. Pulling the old frame frequently exposes crumbling mortar and moisture-damaged block that has to be patched before a new impact-rated frame can be anchored square and sealed. We quote that masonry work up front so the price doesn’t surprise you later. Call (813) 320-9346 to schedule a free measurement.
Plan on four to eight weeks from signed quote to finished install for most custom or impact-rated replacement windows in South Apopka. The lead time isn’t labor. It’s the manufacturer. Custom-sized units for non-standard CBS rough openings are built to order, not pulled from a warehouse shelf. We order everything in writing, fixed price, before the factory starts cutting. Call (813) 320-9346 and we’ll tell you honestly what the current lead times look like for the brands that fit your job.
Yes. We can order custom aluminum jalousie-style windows built to current Florida Building Code wind-load ratings. They’re not cheap, and they’re a specialty order, typically running $2,200 to $3,200 per opening depending on size. But if you want the look that matches a mid-century South Apopka block home and you want it to actually protect the house in a storm, that’s the route. We’ll quote it both ways: the jalousie look and a modern impact-rated casement, side by side on paper. Call (813) 320-9346.
Fog between panes is a seal failure. In South Apopka, the persistent lake humidity and the heat cycling from brutal afternoon sun to damp nights stress seals on older units until they break. Once the seal fails, the insulating gas leaks out and moisture gets in. There is no repair. The sash unit gets replaced, and if the frame is still good, it’s an insert job. Call (813) 320-9346 and we’ll tell you whether you need one sash replaced or a full window.
