ECO Window Systems Windows & Doors in Longwood, FL | TruePane Windows & Doors
We provide independent ECO Window Systems service across Longwood, and the thing that sets our work here apart is simple: we know this city has two completely different window markets. Call (754) 238-2201 for a free estimate. Whether you’re in a 1920s cottage in the Historic Village or a 1970s Sanlando Springs ranch, we service and install ECO 4500, 5700, 9000, and ImpactGuard lines with parts that actually match what’s on your house.
We are not an ECO Window Systems dealer and we’re not manufacturer-affiliated. We’re an independent service provider that’s been rebuilding and retrofitting these units across Central Florida since the line first hit local tract subdivisions. That independence means we tell you the truth about repair versus replace, and we keep a running database of Longwood-specific permit notes and Historic Village approval outcomes that no generic dealer maintains.
Why Longwood Residents Choose Us for ECO Window Systems Service
Most window companies in Seminole County will quote an ECO job, sure. But few of them can tell you which lite pattern the Longwood Historic Preservation Board will approve on West Warren Avenue, or why a 1970s Sanlando Springs slider is binding in July. We can, because we’ve handled both. Dale Kessler founded TruePane in 2008 after spending nearly three decades measuring and setting windows across South Florida, and he still measures every job himself. That’s the kind of company we are. We hire local, train apprentices into journeymen, and we plan to be in Longwood thirty years from now.
A live person answers our phone 24 hours a day, seven days a week. Not a voicemail tree. When you call about your ECO window or door, you get someone who knows what an ECO 5700 roller cartridge is and whether we have one on the truck that week.
Common ECO Window Systems Windows & Doors Problems We Solve in Longwood
- Fogged glass on west-facing ECO 9000 picture windows. Longwood’s afternoon UV is relentless, and the daily heat-cool cycle breaks glazing seals faster than national averages. We see failed between-pane seals on Sanlando Springs picture windows years before the same units fail on the coast. The fix is replacing the insulated glass unit, not the whole frame.
- Worn corner balances and tilted sashes on original ECO 4500 single hungs. Those 1970s CBS ranches still have original single-pane units in a lot of cases. Homeowners often think the frame is warped when the sash won’t stay up. It’s almost always the balance springs, and new balances restore function for a fraction of replacement cost.
- Track corrosion and algae bloom on ECO 5700 sliders near sprinkler overspray. Longwood’s irrigated lawns are hard on slider tracks. The heat-cool cycle bakes mineral deposits into weep holes, and the wet-dry pattern grows algae inside the track. We clean, replace worn rollers, and restore drainage so water stops pooling at the sill.
- Hidden wood rot at sill plates on retrofit ECO inserts in historic cottages. When an ECO insert goes into an original wood frame without proper flashing, humidity gets trapped between the old wood and new aluminum cladding. By the time you see paint peeling, the sill is often soft. We catch that on removal and replace the rotted wood before reinstalling.
- Wind-load failures on original hollow-core exterior doors and single-pane sliders. Most 1970s Longwood homes don’t meet current Florida Building Code wind-load minimums. If you’re going through a wind-mitigation inspection or just want an impact-rated upgrade, we quote ECO ImpactGuard and comparable manufacturer lines side by side on paper.
ECO Window Systems Service in Longwood: What Local Conditions Mean for Your Equipment
Longwood is the only city in Seminole County whose entire downtown core falls under a local Historic Preservation Board Certificate of Appropriateness requirement for window and door replacement. That’s not true in Altamonte Springs, Lake Mary, or Casselberry. Here’s what it means in practice: if you own a Craftsman or Florida cottage in the Longwood Historic Village, you cannot pull a standard Seminole County building permit and start swapping windows. The city’s Historic Preservation Board reviews the project first, and they require replacement windows to match the original lite patterns and profiles. A standard off-the-shelf white vinyl double-hung is often non-approvable in that zone. For ECO owners, that means a replacement job can stall at permitting if the lite pattern doesn’t match. We’ve handled enough of these to know what the board will accept before you waste time and application fees. On the other side of the city, the 1970s tract homes in Sanlando Springs and the Wekiva-area subdivisions have no such review. Those jobs are about engineering: whether the original single-pane aluminum frames can be repaired or whether wind-mitigation pushes a full impact upgrade. One city, two completely different rulebooks.
ECO Window Systems Models & Products We Service in Longwood
We service the ECO 4500 Single Hung, ECO 5700 Horizontal Slider, ECO 9000 Vinyl Picture Window, and ECO ImpactGuard Casement lines. For current ECO series, we stock OE-specification balances, weatherstripping, and replacement sash kits locally for fast Longwood turnaround. For discontinued models or Historic Village-match profiles, we machine custom aluminum extrusions locally rather than forcing a mismatched off-the-shelf unit. We never recommend replacing a whole ECO window when a $60 balance or $40 roller cartridge restores function, unless a wind-mitigation inspection forces an impact upgrade. When impact is required, we quote ECO ImpactGuard alongside PGT, CGI, and other authorized lines so you see the full picture side by side.
ECO Window Systems Service Pricing in Longwood
ECO window and door service in Longwood typically runs $160 to $340 for a single-unit repair such as a balance replacement, roller change, or weatherstripping job. Insulated glass unit replacement for a fogged ECO 9000 runs $280 to $520 installed depending on size and glass package. Full replacement windows with ECO or comparable impact-rated lines start around $700 per opening and go up from there, with historic-district custom lite patterns adding to cost. What drives the price: the unit’s age and condition, whether the Historic Preservation Board review applies, whether we need to machine custom extrusions, and whether wind-load upgrades are in play. Every estimate is free and written line by line. Call (754) 238-2201 to schedule yours.

FAQs - ECO Window Systems Windows & Doors in Longwood
Longwood’s downtown core requires a Certificate of Appropriateness from the city’s Historic Preservation Board before window and door replacement permits move forward. The standard county permit alone is not enough. The board reviews lite patterns and profiles against the original construction. If your ECO unit was installed without COA approval, the permit gets challenged. We can help you through the review, including sourcing or machining matching profiles. Call (754) 238-2201 and we’ll tell you what the board will ask for.
Yes. Repairing your existing ECO 5700 slider with new rollers, track cleaning, and weatherstripping does not trigger impact requirements. It’s a repair, not a replacement. If the unit is beyond repair and you’re outside the Historic Village, a like-for-like replacement is generally acceptable unless a wind-mitigation inspection flags the whole house. Call (754) 238-2201 and we’ll assess the unit honestly.
Usually not. The Historic Preservation Board requires replacement windows to match the original lite pattern and profile of the structure. Standard white vinyl double-hungs with a single-over-single lite pattern don’t match a 1920s Craftsman or Florida cottage’s original windows. That’s why we machine custom aluminum extrusions locally when a historic match is needed. It’s what keeps the permit moving.
West-facing units in Longwood take the full force of Central Florida’s afternoon UV, and the daily heat-cool cycle breaks between-pane seals faster than the national average. It’s a known failure mode on ECO 9000 picture windows in this climate. The fix is replacing the insulated glass unit, typically $280 to $520 installed. Call (754) 238-2201 and we’ll measure it.
The board requires that replacement windows match the original lite patterns and profiles of the building. For a 1920s cottage, that often means divided-lite patterns like 6-over-1 and period-appropriate materials or finishes. Off-the-shelf vinyl units are frequently non-approvable. Our crew on West Warren Avenue pulled an old ECO 4500 that had been installed without COA approval, found the original wood frame 3/8 inch out of square, custom-machined a matching 6-over-1 lite pattern insert, replaced the rotted sill, and got the permit signed off in one cycle. It’s detail work, but it’s what the house requires.
