ECO Window Systems Windows & Doors in Marathon, FL | TruePane Windows & Doors
We provide independent ECO Window Systems service across Marathon, from single-hung sash repairs to full-frame impact retrofits, and also offer Eco Window Systems in Key Colony Beach. The one thing that sets our ECO work apart here is the inspection pass: in Marathon, Monroe County’s wind mitigation inspector will not sign off on a home that still has original jalousie windows in any opening, even a laundry room. That means our ECO service almost always starts with a full opening inventory, not just a repair call. If you need ECO Window Systems work done right the first time, call (813) 320-9346.
Why Marathon Residents Choose Us for ECO Window Systems Service
We have been pulling failed ECO frames out of Marathon’s salt-soaked buildings since before Hurricane Irma rewrote the local code book. That matters when you need someone who knows which gaskets, hinges, and glazing beads fail first on island exposures. ECO Window Systems sales & service is work we do with a respect for the product’s engineering and a clear eye on where it falls short in this climate.
Dale Kessler founded this company on a rule he keeps on the whiteboard: if the pane is not true, the job is not done. He grew up in Seminole Heights and learned the glazing trade at Hillsborough Community College, spending more time on the shop floor than in a classroom. For the better part of two decades he has measured, set, and sealed windows and doors across Florida, including Eco Window Systems repair in Key West, and the work he is best known for is storm-rated installation done tight enough that a follow-up inspection is never a surprise. We bring that same standard to every ECO Window Systems job in Marathon.
We are an independent ECO Window Systems service provider. We are not manufacturer-affiliated or authorized by ECO. That independence means we can tell you plainly when a part is worth the OEM price and when a marine-grade aftermarket roller will outlast the original. We track ECO’s Miami-Dade NOA approvals by model and revision because we are the ones who have to stand behind them during Monroe County’s stricter inspections, just as we do with Homestead Eco Window Systems service.
Common ECO Window Systems Windows & Doors Problems We Solve in Marathon
- Salt pitting on ECO 6000 Series single hung sashes: On canal-front homes in Marathon, brackish spray collects at the bottom weep holes and never fully drains. We regularly see pitting within three to four years, especially on the water-facing elevation. We replace the affected sashes and re-seal the weep channels so drainage actually works.
- Seized roller assemblies on ECO 5000 Series sliding glass doors: Marathon is flanked by the Atlantic on one side and Florida Bay on the other, so the same door track gets hit with salt air from two directions. Rollers corrode and seize. We replace them with marine-grade stainless rollers that hold up far longer than the OEM’s standard hardware.
- Delaminated laminated glass on ECO StormMax units: UV and humidity cycling along Marathon’s coastline causes edge clouding around the glazing bead. A wind mitigation inspector will reject that condition during re-certification. We replace the insulated glass unit and confirm the NOA still applies before we leave.
- Compression gasket failure on ECO 7000 Series casement windows: East-facing casements on the ocean side of US-1 whistle under trade winds even with the lock fully engaged. The gasket compresses unevenly and loses its seal. We replace it with a neoprene gasket cut to the exact extrusion profile.
- Jalousie window non-compliance: Many older Marathon homes still have original louvered jalousie windows that provide almost no wind or impact resistance. Monroe County will not pass a wind mitigation inspection while they remain. We replace them with ECO impact-rated units and handle the opening modification properly.
ECO Window Systems Service in Marathon: What Local Conditions Mean for Your Equipment
Marathon is the only city in the Florida Keys where Monroe County’s HVHZ code requires impact-rated windows for every replacement on a structure that’s elevated on pilings, and the county’s wind mitigation inspector refuses to sign off if the original 1980s jalousie frames are still present in any opening, even a laundry room window. That single fact changes how we approach every ECO Window Systems job here. A homeowner in Margate, Medley, or Eco Window Systems in Coral Gables can replace windows one at a time as budget allows. In Marathon, a single missed louver unit will fail the whole-house re-certification, so our retrofits almost always begin with a full inventory of jalousie openings. We were called to a 1981 CBS ranch on 54th Street Ocean after the homeowner’s wind mitigation re-inspection failed because the original aluminum jalousie windows in two bedrooms were still in place. Our tech measured the non-standard rough openings and ordered custom ECO 7000 Series impact casements with marine-grade stainless friction hinges, because the standard zinc hardware would have seized within two years from the salt spray off the Atlantic just 200 yards away. After pulling the old jalousie clips, we installed full-frame replacements and the homeowner passed their re-inspection three weeks later, cutting their premium by more than the cost of the two windows.
ECO Window Systems Models & Products We Service in Marathon
We service the ECO 7000 Series Impact Casement, ECO 6000 Series Single Hung, ECO 5000 Series Sliding Glass Door, and ECO StormMax Fixed/Picture Window. For anything touching the glazing, weather seal, or structural frame, we use genuine ECO Window Systems components. Off-brand weep hole covers and sash clips rarely match the extrusion geometry and can void the product approval. For rollers, handles, and non-structural hardware, we will install marine-grade aftermarket parts when they outperform the OEM’s standard option, and we will tell you up front if a full frame replacement costs less than chasing multiple failing parts. We keep common ECO gaskets, rollers, and glazing beads in our local stock for faster Marathon turnaround.
ECO Window Systems Service Pricing in Marathon
ECO Window Systems service in Marathon typically falls between $150 and $450 for common repairs like roller replacement, gasket work, or sash re-sealing. Full-frame impact retrofits run higher because Marathon’s HVHZ code requires Miami-Dade NOA approved units, and the rough openings in older CBS homes often need modification. What drives the cost more than anything here is the inspection requirement: if the work will not pass a wind mitigation check, it is not done. That is our standard, not an upsell.
A free estimate includes a full opening inventory, a review of your existing ECO units against current NOA approvals, and a written line-item quote. No surprises on the bill, no second appointment left hanging. Call (813) 320-9346 for an exact quote. If it needs to be in writing to be true, we will put it in writing.

FAQs - ECO Window Systems Windows & Doors in Marathon
Monroe County inspectors check every opening, not just the ones you replaced. If any original jalousie windows or non-impact-rated frames remain, even in a small utility opening, the whole-house re-certification fails. We start with a full opening inventory and replace every non-compliant unit before you schedule the re-inspection. Call (813) 320-9346 and we will walk the property with you for free.
Yes, and it is not close. Canal-front doors in Marathon get brackish spray from below and salt air from both the Atlantic and Florida Bay sides. Standard zinc rollers and hardware corrode and seize within a few years. We replace them with marine-grade stainless rollers and neoprene seals that are spec’d for this exact exposure. Call (813) 320-9346 and we will tell you what is on your door right now.
No. Monroe County’s wind mitigation inspector will not sign off on a house with original jalousie frames in any opening, storm panels or not. The louvered design itself provides virtually no wind resistance, and panels cannot fix that. The only path to a passing inspection is full replacement with Miami-Dade NOA approved impact units like the ECO 7000 Series. Call (813) 320-9346 for a free estimate on the retrofit.
That edge clouding is delamination of the laminated glass interlayer, caused by UV and humidity cycling that is intense on Marathon’s island exposure. The constant salt air accelerates the breakdown along the glazing bead. This condition will fail a wind mitigation re-inspection, so it is not just cosmetic. Call (813) 320-9346 and we will assess whether the unit needs replacement or if the seal can be recovered.
Every ECO Window Systems unit has a NOA number and product approval label, but the revision matters. We track ECO’s Miami-Dade NOA approvals by model and revision because Monroe County inspectors check the exact match, not just the brand name. We check every unit’s label against the current approved list during our free estimate. Call (813) 320-9346 and we will verify your windows at no charge.
