We’re TruePane Windows & Doors, and we’ve been setting windows square across Florida lake country since 2008. Dale Kessler founded this company on a simple rule: if the pane is not true, the job is not done. That rule matters more out here than it does in a tight HOA subdivision, because Lake Mary Jane homes face conditions most inland Orlando suburbs never see.
Why TruePane Windows & Doors Is Lake Mary Jane’s Preferred Window Replacement Company
Lake Mary Jane isn’t a city with a building department on Main Street. It’s unincorporated Orange County, which means your window permit crosses a county desk, not a municipal one. We’ve pulled enough of those permits to know exactly what the inspector will flag before we ever hand you a quote. That’s not a sales talking point. It’s the difference between a job that passes first inspection and one that stalls for six weeks while you argue about wind-load ratings on a like-for-like swap.
Our techs are background-checked and uniformed. They measure every opening twice. They quote manufacturer lines side by side on paper so you see the actual numbers, not a verbal estimate you have to take on faith. We register both warranty layers in writing before the truck leaves your driveway. And we back the workmanship with a 90-Day Done Right Promise that doesn’t require you to produce paperwork from three years ago to get a fix. If it’s not done right, we make it right. No arguing.
We serve the neighborhoods around the lake itself, plus the acreage homes along the eastern lakefront and the older lots further out near the St. Johns River watershed. Dispatch is coordinated from our South Florida office, and crews roll to Lake Mary Jane on a set schedule, not a maybe-whenever basis.
Our Window Replacement Services in Lake Mary Jane
Full Frame Replacement
Most Lake Mary Jane homes built in the 1970s through the 1990s are sitting on original aluminum single-pane frames. Around the lake, those frames corrode fast. Full frame replacement pulls everything down to the rough opening so we can address rotted sub-sill, failed flashing, and water intrusion that a retrofit would hide. On a 1970s lakefront home off Lake Mary Jane Road, our crew found original single-pane aluminum double-hungs with seal failure and corroded jambs. We pulled full frames back to rough opening, corrected the water intrusion at the sill, and installed impact-rated casement units with low-E glass and argon fill, then flashed the openings with tape to county code before inspection. That’s the standard we bring to every full-frame job out here.

Insert Window Replacement
If your frames are square, dry, and structurally sound, an insert replacement preserves them while replacing the sash, glass, and hardware. It’s faster and costs less than full frame, which matters when you’re looking at a dozen openings. But Lake Mary Jane humidity has a way of hiding rot behind trim, so we inspect the rough opening before we commit to insert versus full frame. We won’t sell you an insert on a frame that won’t carry it another ten years.

Storm Window Replacement
Lakeside exposures on Lake Mary Jane take wind differently than inland lots. Open water funnels tropical storm gusts straight into your west and east facing walls, and the code in this zone accounts for that. Storm window replacement here usually means impact-rated glazing, not a basic laminated pane. We’ll tell you honestly whether the inspector will accept a storm window or demand a full impact-rated unit, because we’ve stood in front of that county inspector more times than we can count.

Energy-Efficient Upgrade
Swapping single-pane aluminum for low-E insulated glass with argon fill drops your cooling load measurably, and in Lake Mary Jane’s nine-month summer, that’s real money. The wall of humidity off the lake also means your old windows are fighting condensation year-round, not just in August. An energy-efficient upgrade fixes both problems at once. We quote Andersen, PGT, and Marvin lines alongside mid-market options so you can see the cost difference on paper, in your kitchen, before you commit.

You’ll see every manufacturer line quoted side by side on paper, with warranty durations stated in writing. No verbal handshake on warranty coverage.
Common Window Replacement Problems We See in Lake Mary Jane Homes
- Condensation and fog between panes. Insulated glass seals fail fast near the lake because persistent humidity works the desiccant inside the spacer bar until it saturates. We see IGU failures on ten-year-old units regularly around Lake Mary Jane, where inland Orlando units would run fifteen to twenty years.
- Corroded aluminum frame hardware. The same moisture that kills seals also eats aluminum tracks, locks, and jamb hardware. A window that won’t lock or a sash that won’t slide is often a corrosion problem, not a housekeeping problem.
- Failed wind-load checks during Orange County permit review. This is the one homeowners never see coming. You file a permit for a simple glass swap, and the county kicks it back because the existing frame doesn’t meet current Florida Building Code wind-pressure ratings for your lakeside zone. Now you’re replacing the entire unit. We flag this before you ever file.
- Warped or rotted wood frames on older lakefront homes. Homes built before modern flashing and sill-pan practices around Lake Mary Jane often have water intrusion at the rough opening that nobody sees until the window comes out. We address what we find at the sill, not just what’s visible from the interior.
Pricing for Window Replacement in Lake Mary Jane, FL
Line-item pricing for Lake Mary Jane window replacement breaks down like this, based on what we’ve quoted and installed over the past several years:
- Insert window replacement: $450-$900 per opening, depending on glass package and hardware
- Full frame replacement (non-impact): $900-$1,400 per opening
- Full frame replacement with impact-rated glazing: $1,200-$2,800 per opening, higher for lakeside walls or custom sizes

- Permit costs through Orange County Building Division: typically $150-$400 depending on job scope
What moves the number: whether we’re doing inserts or full frames, whether the inspector requires impact-rated glass, how many openings, and whether we find rot at the rough opening once the old unit comes out. We scope all of this during the estimate, not after the contract is signed. Call (813) 320-9346 for a free written estimate with fixed pricing. No change orders at the end, no surprise line items.

FAQs - Window Replacement in Lake Mary Jane
Yes. Lake Mary Jane is unincorporated Orange County, so all window replacement permits run through Orange County Building Division, not a city office. Even a like-for-like swap requires the new unit to meet current Florida Building Code wind-pressure ratings for your zone. Call (813) 320-9346 for an exact read on your specific openings, and we’ll tell you what the inspector will require before you file.
The lake and surrounding wetlands keep ambient humidity high year-round, which saturates the desiccant inside the spacer bar faster than drier inland air would. That means seals on dual-pane units fail within eight to twelve years around the lake, versus fifteen to twenty in places like Altamonte Springs. We quote glass packages built for high-humidity performance on every Lake Mary Jane job, not the same spec we’d put in a house ten miles inland.
Sometimes, but not often on the lakeside elevation. If the frames are aluminum, square, and free of corrosion, inserts are an option. But the wind-load requirement for your zone often means the frame itself doesn’t pass code, forcing full frame replacement. We inspect every opening before we recommend one path or the other, and we’ll show you the county’s wind-zone requirement on paper so you’re not taking our word on faith.
If the frames are structurally sound, we can often replace just the insulated glass unit (IGU) without touching the frame. In Lake Mary Jane specifically, we check the frame for hidden corrosion at the weep system and sill before recommending glass-only, because lake humidity hides frame damage that will fail within a few years. A free estimate at (813) 320-9346 gets you a straight answer on glass-only versus full replacement.
We treat lakeside walls as wind-load critical elevations and spec impact-rated units that exceed the minimum code requirement for your exact zone. That includes proper anchoring into the header and sill, flashing tape at every rough opening, and documentation the county inspector will accept on first pass. It costs more than a standard inland window, and we’ll show you the dollar difference on the estimate rather than hiding it until the job is underway. Call (813) 320-9346 to schedule a free estimate.
