New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Clewiston pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.

ECO Window Systems Custom & Geometric Windows in Clewiston: What to Know First
As an independent ECO Window Systems service provider in Clewiston, we measure, specify, and install custom and geometric windows from ECO’s product lines with the same written-price-first protocol we apply to every manufacturer we carry. A typical ECO Window Systems custom opening in Hendry County runs $1,800 to $4,500 installed, depending on whether we’re working with a standard geometric conversion or a full arched impact-rated unit with custom glazing. We turn most measured surveys into written quotes within 48 hours, and the price on that document is the price on the final invoice.
This page is for Clewiston homeowners who already know ECO Window Systems makes the window they want - a radius-top unit for a gable, a trapezoid to match a roofline, or an oversized fixed picture window for a lake-facing wall - and need an installer who will document the rough opening, name the exact product code, and put the number in writing before any work starts. Call (863) 509-1135 to schedule your measured survey. You’ll keep a copy.
How ECO Window Systems Products Fail - and How We Fix Them

- EG Series geometric sash seal fatigue in Clewiston’s wet season. The EG Series uses a dual-durometer bulb seal that compresses well when new, but the combination of 90-degree July humidity and daily afternoon thermal cycling around Lake Okeechobee hardens the outer skin by year four. We’ve replaced these seals on a dozen homes south of Sugarland Highway where the afternoon sun hits the gable end directly. We pull the OEM seal profile, match the compression set to the frame extrusion, and document the durometer reading so the owner has a baseline.
- ECO 9000 Series arched unit hinge-side sag on wide openings. The 9000 Series arched ventilating units use a continuous hinge design that works fine at 24 inches wide, but at 36 inches and above the weight of laminated impact glass pulls the sash off plumb. We see this in newer construction near the Clewiston Golf Course where builders spec’d wide radius-tops for curb appeal. Our fix: we shim the hinge jamb to true plumb, replace the factory hinge with a heavy-duty stainless pivot set rated for the actual glass weight, and re-measure the daylight opening before the sash goes back in.
- Custom fixed geometric fogging from capillary tube failure. ECO’s large fixed geometrics - the triangles and trapezoids above patio doors - ship with capillary tubes to equalize pressure during altitude transit. If the tube isn’t sealed at installation, or if the sealant degrades, moist air enters the IGU and fogs the glass from the inside. This isn’t a seal failure; it’s an assembly detail. We drill, vent, and reseal with butyl and silicone secondary, or replace the IGU if the desiccant is saturated. Either way, we photograph the tube location and the repair for the job record.
- Aluminum frame thermal expansion noise in oversized ECO units. ECO’s custom aluminum frames expand roughly 1/8 inch per 10 feet of frame on a 40-degree temperature swing. In Clewiston, that’s a normal March afternoon. When the frame grows against a tight rough opening, the popping sound carries through the wall. We find this on west-facing great room units where the builder framed to net size. Our fix is to pull the trim, cut back the framing to allow proper shim space, and re-install with composite shims that don’t crush like pine. The frame moves silently; the wall stays intact.
- Impact-rated geometric glazing delamination at the radius. ECO’s impact geometrics use laminated glass with a .090 interlayer minimum. On tight radius curves - under 24 inches - the interlayer can separate from the lite at the inside of the curve, creating a visible bubble that fails the Miami-Dade HVHZ visual inspection standard. We’ve caught this on pre-installation receiving inspections twice in Clewiston, both times on special-order units. We reject the glass at our shop, document the defect with photos under polarized light, and re-order on ECO’s warranty. The customer never sees a bad unit.
Before
AfterOur ECO Window Systems Custom & Geometric Windows Process
- 1
Measured survey with the document you keep. Sonia Raman or a verified crew member arrives with a printed license number, measures the rough opening in three places each direction, notes wall thickness and structural load path, and records frame squareness with a digital level. You get a copy before we leave.
- 2
Product specification against the opening, not the catalog. We match ECO’s available profiles to your actual frame conditions. If the EG Series geometry you want won’t clear the roofline, we say so and show you the CWS or ES Windows alternative that will. No margin-driven upsell; Haven Clause 5.
- 3
Written quote with line-item pricing. Every component is named: frame extrusion, glazing package, hardware finish, interior/exterior color, and installation labor. The total matches the survey document. If it doesn’t, we made a mistake and we eat it.
- 4
Fabrication oversight and receiving inspection. For custom ECO orders, we inspect at receiving for the delamination, seal, and dimension checks that factory QC sometimes misses on special shapes. We photograph everything.
- 5
Installation with rough-opening prep documented. We pull and replace frames as needed, never bury a bad measurement behind trim. Composite shims, structural fasteners per ECO’s published schedule, and sealant with the published shore hardness for Clewiston’s climate zone.
- 6
Final measure, photo record, and written warranty. We re-measure the installed unit for square and operation, photograph the completed work and the surrounding condition, and stamp the 365-Day Done Right Promise on your invoice. You keep all of it.

Why Clewiston Homeowners Call Sightline Windows & Doors Clewiston for ECO Window Systems Work
We’ve installed and serviced ECO Window Systems products in Clewiston long enough to know which extrusion colors from 2017 don’t match the current dye lot, and which geometric profiles ECO has retired without updating their published catalog. That specificity matters when you’re trying to match a gable-end triangle on a home near the U.S. Sugar Corporation corridor.
The Haven Standard governs every job: written price first, verified crew, evidence on every visit, no surprises. If we specify an ECO unit and the lead time stretches, we have PGT, CGI, CWS, and ES Windows lines with equivalent performance tiers and published price ranges - specified by what your opening requires, not by what we have in stock. The 365-Day Done Right Promise covers the installation and the product specification. If it’s not done right, we make it right. That’s not a courtesy; it’s Clause 5.
Our technicians are background-checked, uniformed, and identified by license number before arrival. Calls are answered by a live person, 24/7. And every job leaves a documented photo record, because evidence is the only proof that holds up.
FAQs

No, provided the installation follows ECO’s published installation instructions and uses OEM or ECO-approved components. As an independent ECO Window Systems service provider, we install to the manufacturer’s published requirements, document our methods with photos, and use only parts that meet or exceed ECO’s specifications. If a warranty claim arises, our photo record and written scope support your case with ECO directly. Call (863) 509-1135 if you have a specific concern about your existing warranty terms.
Standard ECO geometrics typically ship in 6-8 weeks from order; complex radius units or custom color matches can run 10-12 weeks. We don’t quote lead times we haven’t verified with the factory that week. If your project timeline is fixed, we maintain equivalent geometries in PGT, CGI, and CWS lines with sometimes shorter availability - we’ll show you the options and the price difference. Call (863) 509-1135 to check current lead times.
Most fogged ECO geometrics can be repaired by IGU replacement rather than full frame replacement, saving roughly 60% of the cost of a new unit. We drill, vent, and replace the sealed glass unit if the frame extrusion is sound and the hardware operates correctly. If the frame is corroded or the sash is out of square, we’ll tell you before we order glass. Call (863) 509-1135 for a free assessment.
Yes, for any installation that requires a permit under Hendry County or City of Clewiston building codes. We pull the permit, schedule the inspection, and pass it. The permit cost is listed as a line item in your written quote, not added later. You receive the approved inspection card and the photo record together. Call (863) 509-1135 to confirm whether your specific project requires permitting.
We tell you immediately, show you the ECO replacement profile with the published performance data, and quote equivalent geometries from PGT, CGI, CWS, or ES Windows if ECO no longer serves that application. We don’t sell discontinued stock as “close enough” and we don’t substitute without written approval. Measure it right the first time. Everything after that is just paperwork. Call (863) 509-1135 to verify availability for your specific geometry.
Ready to move forward? Call (863) 509-1135 to schedule your free measured survey. You’ll receive a written quote you can compare, a documented photo record when the job is done, and the 365-Day Done Right Promise stamped on every page. No voicemail queue. No callback window. A live person answers.
