ECO Window Systems Custom & Geometric Windows in Weston: What to Know First
As an independent ECO Window Systems service provider, we measure, order, and install custom and geometric windows for ECO Window Systems products in Weston homes, with most projects running two to four weeks from survey to final seal check. Our written quote matches our measured survey exactly - Haven Clause 1 - and we do not start work until you have that price in hand. This page is for Weston homeowners who need arched, curved, oversized, or otherwise non-rectangular ECO Window Systems units replaced or newly installed, and who want to know what the product actually costs before a crew arrives. Call (754) 812-9260 to schedule your measured survey.
How ECO Window Systems Products Fail - and How We Fix Them
- ECO Window Systems ES-8000 series geometric units: The thermal break in the aluminum frame separates at the weld points on radius-top windows, especially where the curved header meets the jambs. We’ve traced this to the expansion differential between the extruded arch and the straight-leg sections in Weston’s afternoon heat spikes. We remove the sash, re-weld with matching alloy filler, and pressure-test the thermal bridge before re-glazing.
- ECO Window Systems custom impact-laminate delamination: On their coastal-rated geometric units, the interlayer between glass lites creeps at the edges of shaped cuts - circles, hexagons, and narrow arches are the worst. The symptom is a cloudy perimeter that owners mistake for seal failure. We source replacement lites through ECO’s laminated-glass spec, not generic tempered, because the interlayer thickness varies by series year.
- ECO Window Systems fixed geometric sash warping: The ES-6000 fixed triangles and trapezoids we see in Weston Hills and Windmill Ranch accumulate racking stress when the rough opening settles. The miter joints open at the exterior gasket line first. We don’t just caulk over it; we pull the sash, shim the frame to three reference points, and re-square before reinstallation - Sonia Raman checks each one personally on non-rectangular frames because the window does not care how confident you were.
- ECO Window Systems oversized operator hardware fatigue: Custom picture units over 72 inches wide use a heavier-duty hinge set that ECO sources from a single Italian OEM. After five to seven years in South Florida’s salt air, the stainless pivot develops galling. We stock the exact replacement hinge pack; aftermarket hardware from the big-box suppliers doesn’t carry the same load rating and will sag the sash within eighteen months.
- ECO Window Systems low-E coating edge failure on shaped glass: When geometric glass is cut from rectangular stock, the low-E edge is exposed at the perimeter. In Weston’s high-UV environment, that exposed silver oxide oxidizes from the cut line inward, visible as a bronze band that widens each year. We specify edge-deletion banding on replacement geometric lites - a factory option most owners don’t know exists - to stop the progression at the cut.
Our ECO Window Systems Custom & Geometric Windows Process

- 1
Measured survey you keep. We arrive with digital calipers, a laser level, and a camera. You get the dimension sheet and frame-condition photos before we leave. For geometric work, we also record the radius points or chord dimensions - ECO’s factory needs these to the sixteenth.
- 2
Written scope and price. Haven Clause 1: the quote is the survey document, plus line-item material and labor. No change orders unless you alter the spec.
- 3
Parts decision: OEM or verified equivalent. For ECO Window Systems, we default to OEM glass and hardware. On discontinued series, we source through our verified aftermarket channel - never generic, always spec-matched - and we document the substitution in writing.
- 4
Installation with live reference checks. The crew sets the frame, checks square from three points, shims, anchors, then seals with the specified backer rod and sealant for the exposure. Geometric units get extra attention at the radius transitions where air infiltration starts.
- 5
Operational test and photo record. Every moving part is cycled. Every seal line is photographed. You get the image folder and the 365-Day Done Right Promise stamped on the final invoice - Haven Clause 5.
- 6
Cleanup and documentation handoff. The measured survey, the written scope, the photo record, and the warranty document. All in your hands before we leave.

AfterWhat ECO Window Systems Custom & Geometric Windows Costs in Weston
| Scenario | Typical Range |
|---|---|
| Standard geometric replacement (triangle, trapezoid, circle) - ECO Window Systems ES-6000/8000 series, single unit | $1,800 - $3,400 |
| Large arched or radius-top unit - ECO Window Systems impact-rated, including laminated glass | $3,200 - $5,800 |

| Multi-unit geometric project - 3+ shaped windows, coordinated install | $7,500 - $14,000 |
| Hardware-only repair - hinge, operator, or lock replacement on existing ECO geometric sash | $340 - $680 |
What moves the price: the glass spec (impact-laminated vs. tempered), the frame depth (2-inch vs. 2.5-inch for wind-borne debris zones), and whether the rough opening needs reframing for square. We pull permits where Weston requires them and pass inspection - that’s included, not extra. Call (754) 812-9260 for your exact written quote; estimates are free.
Why Weston Homeowners Call Sightline Windows & Doors Weston for ECO Window Systems Work

We’ve installed and serviced ECO Window Systems products in Weston since the early ES-series launches, and we’ve logged the failure patterns specific to this manufacturer’s extrusion and glass sourcing. When ECO Window Systems parts run long-lead - which happens on older geometric series - we don’t leave you waiting; we draw from our eight verified manufacturer lines, including PGT, CGI, CWS, and ES Windows, to find a performance-matched alternative and document why it meets the opening’s requirements.
Our crews are background-checked, uniformed, and identified by license number before arrival - Haven Clause 3. The phone is answered by a live person, 24/7. And the 365-Day Done Right Promise is not a courtesy; it’s stamped on every job under the Haven Standard we’ve operated under since 2012. Eighteen thousand openings, every one with a written price first and a photo record at the end.
FAQs
No - provided the repair uses OEM-spec parts and documented procedures. As an independent ECO Window Systems service provider, we follow the manufacturer’s published service guidelines and record every part number. We warranty our workmanship separately under the 365-Day Done Right Promise, so you’re covered either way. Call (754) 812-9260 if you want us to review your warranty status before we start.
Standard geometric shapes from current ECO Window Systems series typically ship in ten to fourteen business days. Discontinued series or custom radius cuts can run four to six weeks. We don’t guess at delivery; we confirm factory lead time at the survey stage and write it into your scope. If your opening is exposed in the meantime, we spec and install a temporary board-up at cost - Haven Clause 5, no surprises.
Yes, within the limits of what ECO Window Systems still stocks. We carry a color-matched sample kit to the survey and compare under natural light - Weston’s afternoon sun shifts bronze and champagne tones significantly. If the original color is discontinued, we show you the closest current match and document the difference in writing before you approve the order.
Replace if the frame is racked more than 3/16 inch out of square, if the thermal break is separated at multiple weld points, or if the series is discontinued and parts are unobtainable. Repair if the failure is isolated to glass, hardware, or sealant. We make this call at the survey and explain the math - repair cost vs. replacement cost vs. expected remaining service life - in the written quote. Call (754) 812-9260 to schedule the assessment.
Both. For new construction in Weston, we coordinate with your framer to set the rough opening dimensions before the ECO Window Systems custom unit is ordered - geometric windows do not tolerate field trimming. For replacement, we measure the existing frame and specify the replacement to fit without disturbing interior trim where possible. Either way, the price is written before work starts.
