ECO Window Systems Windows & Doors in Marathon, FL | TruePane Windows & Doors
We provide independent ECO Window Systems service across Marathon, from diagnosis and repair to full-frame replacement of impact-rated units. The one thing that makes our ECO work here different: we understand that every window swap on this island is a code-compliance job first, because Marathon sits inside Florida’s High Velocity Hurricane Zone. Call (754) 238-2201 for a free estimate, and we’ll tell you exactly what your openings need before anyone touches a saw.
Why Marathon Residents Choose Us for ECO Window Systems Service
Our crews have been diagnosing and replacing ECO Window Systems product lines in Marathon’s HVHZ market since the post-Irma rebuild. That daily focus on NOA documentation and salt-driven corrosion patterns matters more here than anywhere else in the state. Dale Kessler grew up in Kendall, trained at Miami Dade College’s vocational program, and has been setting windows in South Florida for going on three decades, including Homestead Eco Window Systems service. He still measures every job himself. Measure it right the first time, or plan on coming back.
We run ECO Window Systems sales & service calls the way a glazier should: background-checked uniformed technicians, both warranty layers registered in writing before the truck leaves the driveway, and a Done Right Promise that covers the workmanship with no paperwork fights. If the pane is not true, the job is not done.
We’ve been serving Marathon service area homeowners long enough to know which streets took the worst of Irma and which older CBS blocks still have original jalousie frames hiding behind drywall. That local memory saves you money on the estimate and headaches at the permit counter.
Common ECO Window Systems Windows & Doors Problems We Solve in Marathon
- Salt-induced pitting and white corrosion bloom on ECO aluminum frames. Marathon’s narrow coral-limestone island puts salt air on every facade, 360 degrees, with no inland buffer. Ocean-facing elevations on Key Vaca typically show visible pitting within 2 to 4 years of install. We inspect frame channels and fasteners before recommending repair versus replacement.
- Seized or stripped ECO operator arms on casement windows. The 5700 casement’s operator mechanism is the first thing to fail under constant salt air when maintenance cycles slip. We see frozen arms on Atlantic-facing rooms more than anywhere else. If the frame is true, we replace the operator with OEM or marine-grade stainless hardware and re-seal the perimeter.
- ECO 9000 sliding glass door roller bearings seize from omnidirectional salt spray. When the rollers bind, the panel gouges the track and the door stops sliding without real force. We replace rollers and realign the track, or recommend a full panel swap if the track is chewed through. Marine-grade aftermarket rollers match Marathon’s corrosion profile better than standard OEM on older doors.
- Weep hole blockages in ECO frame channels from wind-driven salt crust. Even with intact seals, interior seepage can trace back to weep holes plugged solid with salt. We clear the channels, verify drainage, and check the sill pan for the next storm. This is a routine Marathon repair that mainland shops rarely see.
- Racked or heavily pitted ECO frames on post-Irma rebuilds. Some rebuilds were rushed, and we find units installed out of square or with frames already compromised by salt. When the frame is racked, we do not patch it. We recommend full replacement with a current NOA-certified ECO unit sized correctly for the opening.
ECO Window Systems Service in Marathon: What Local Conditions Mean for Your Equipment
Marathon’s original 1950s through 1970s concrete block homes were framed around the slim profile of jalousie windows, and that legacy shapes nearly every ECO installation on the island. Modern NOA-certified impact units are deeper and wider than jalousie frames, which means the rough opening is almost always the wrong size. On a standard mainland swap, the new window drops into the old hole. Here, the block has to be cut larger or infilled, and Monroe County inspectors check that work specifically during permit close-out. If the opening is not converted correctly, the NOA listing is void and the installation will not pass. We handle the cutting, the infill, the anchor spacing, and the NOA documentation as one scope, because in Marathon they are one job.
Our crew recently replaced seven jalousie openings in a 1963 CBS home near Sombrero Beach, including an ECO 5700 casement on the Atlantic-facing wall that had a frozen operator arm from salt exposure. We cut the rough openings larger to fit the new impact units, pulled an updated NOA for each, and passed Monroe County inspection on the first visit. That is the standard, not the exception.
ECO Window Systems Models & Products We Service in Marathon
We service the ECO 4500 Single Hung, ECO 5700 Casement, ECO 9000 Series Sliding Glass Door, and ECO 700 Series Awning. We use OEM ECO hardware like handles, balances, and rollers when lead times allow. For older discontinued lines, we source marine-grade aftermarket stainless steel hardware that matches Marathon’s corrosion profile. We repair only when frames and glass are intact. Any racked or heavily pitted ECO unit gets a full replacement recommendation, and we quote manufacturer lines side by side on paper so you see exactly what you are buying. We are an authorized installer for more than a dozen manufacturers, but for ECO specifically, we are independent, not factory-authorized, including Eco Window Systems in Coral Gables.
ECO Window Systems Service Pricing in Marathon
Service call diagnostics in Marathon typically run $75 to $150, and that amount is credited toward the repair if we do the work. Replacing a single ECO 4500 single hung with a new NOA-certified impact unit generally lands between $900 and $1,600 installed, depending on whether the rough opening needs cutting or infill. An ECO 9000 sliding glass door replacement runs $2,500 to $4,800 installed, with concrete work and NOA documentation included in that figure. A full-frame replacement of three to five jalousie openings in an older CBS home typically falls between $5,000 and $12,000, driven by the masonry conversion, not just the window cost. Our free estimate includes a written line-item quote, so you see the labor, the materials, and the permit scope separately. Call (754) 238-2201 to schedule yours. We offer a permanent 5% discount for seniors and veterans, and a free written repair estimate.

FAQs - ECO Window Systems Windows & Doors in Marathon
Yes. Marathon sits inside the HVHZ, which means every window and door replacement, regardless of which wall it faces, must carry a Miami-Dade Notice of Acceptance. There is no interior-room exemption in Monroe County. We pull the current NOA for each ECO unit before installation and include that documentation with the permit close-out. Call (754) 238-2201 and we’ll walk you through what your specific openings need.
Marathon is a narrower island than Key West, with the Atlantic on one side and Florida Bay on the other, which means salt air reaches every facade with less distance to slow it down. Eco Window Systems repair in Key West has protected interior streets. Marathon’s Atlantic-facing elevations get direct wind-driven salt, and the 4500’s aluminum frame will show pitting faster there. Annual inspection of frame channels and weep holes is the cheapest protection. Call (754) 238-2201 to have your frames checked before the next storm season.
Almost never. The original jalousie rough openings are too shallow and too narrow for modern NOA-certified ECO impact units. The opening must be cut larger or infilled for the new frame, and Monroe County inspects that conversion. We do the concrete work and the window installation as one scope, so the NOA and the permit close-out stay clean. Call (754) 238-2201 for a free estimate on your specific openings.
Yes. The standard ECO 9000 rollers seize under omnidirectional salt spray faster here than anywhere on the mainland, and when they seize, the panel gouges the track. We recommend marine-grade stainless steel rollers on every 9000 service in Marathon, whether it is a repair or a fresh install. The cost difference is small. The lifespan difference is measured in years. Call (754) 238-2201 and we’ll quote it on paper.
It depends on your HOA’s design standards. Most Marathon HOAs care more about the NOA compliance and finish color than the operator style, but some require like-for-like. We provide the NOA and the line-item quote your HOA board will ask for. Call (754) 238-2201 and we’ll help you prepare the submittal.
