ECO Window Systems Custom & Geometric Windows in Davie: What to Know First
We provide independent ECO Window Systems service for custom and geometric windows in Davie, with most measured surveys scheduled within 48 hours of your call. A typical custom ECO Window Systems opening runs $2,800-$6,400 installed, depending on shape complexity and whether the existing frame can stay or needs full replacement. We write that price during the first visit; the document you keep and the final invoice are the same number.
This page is for Davie homeowners who already own ECO Window Systems products and need arched, curved, geometric, or oversized custom units repaired or replaced. That includes the Pine Island Ridge area, where we’ve done full-frame geometric replacements on 1980s homes that settled enough to make retrofit inserts impossible. Call (754) 254-8492 to schedule your measured survey.
How ECO Window Systems Products Fail - and How We Fix Them
- ECO 9000 Series arched tops: seal failure at the springline. The curved aluminum extrusion in the 9000 Series meets the rectangular frame at a stress point we call the springline. In Davie’s humidity cycle, that joint works against the glazing tape until argon escapes and you see fog at the curve’s base. We don’t just reglaze; we measure the radius with a digital contour gauge and order a replacement sash with the factory-matched thermal break, not a flat-glass retrofit cut to fit.
- ECO Impact Plus geometric units: corner delamination in gable-end triangles. The Impact Plus line uses a heavier interlayer for hurricane rating, but in triangular and trapezoid shapes, the laminated glass can pull at acute corners after repeated thermal cycling. We’ve found this on Davie homes with west-facing gables. Our fix is a full sash replacement with the updated ECO corner-gusset design, or if the series is discontinued, a matched specification from our CGI or CWS lines that preserves the impact rating without a field modification that voids your documentation.
- ECO Classic double-hung with custom radius tops: balance system misalignment. When the curved top sash is heavier than the rectangular bottom, the standard ECO block-and-tackle balances lose calibration and the lower sash drifts. We see this in oversized openings over 48 inches wide. We calculate the actual sash weight and install calibrated spiral balances rated for the combined load, not the stock part that came with the original unit.
- ECO architectural fixed polygons: frame racking in stucco returns. Hexagon and octagon ECO fixed units rely on a perfectly square rough opening. Davie’s sandy soil and older slab construction let the stucco return shift, racking the frame until the operable adjacent units bind. We diagnose with a laser plumb, then either shim and re-anchor the existing frame or specify a replacement with adjustable subsill to absorb future movement.
- ECO oversized picture units: IG unit deflection and seal breach. ECO’s maximum stock dimension is 60 by 96 inches; beyond that, you’re in custom territory. We’ve replaced failed oversized ECO picture windows in Davie’s newer construction where the original installer didn’t spec a thick enough glass lite for the span. The glass bows, the edge seal works, and moisture enters. We specify the correct glass thickness and spacer depth for the span, documented in the written scope before we order.
Our ECO Window Systems Custom & Geometric Windows Process

- 1
Measured survey and shape documentation. We arrive with a digital contour gauge, laser measure, and camera. For geometric shapes, we trace the actual curve or angle, not the rough opening. You keep the measured survey.
- 2
Frame condition assessment. We check whether the existing ECO frame is square, plumb, and structurally sound. In Davie’s older homes, especially near Pine Island Ridge, we often find the frame has racked with the slab and needs full replacement rather than sash-only.
- 3
Parts specification: OEM or matched equivalent. If ECO still produces the series, we quote OEM. If discontinued, we specify from our verified lines - CGI, CWS, ES Windows, or PGT - matched by U-factor, SHGC, and impact rating. We note the source in writing.
- 4
Written scope and fixed price. Haven Clause 1: the quote you sign is the invoice you pay. No change orders for conditions we should have seen at survey.
- 5
Installation and live testing. We install, seal, and test every operable unit for function and every fixed unit for visible seal integrity. Photos go to your file before we leave.
- 6
Documentation handoff. You receive the photo record, the completed scope with any field notes, and the 365-Day Done Right Promise stamped under the Haven Standard.

AfterWhat ECO Window Systems Custom & Geometric Windows Costs in Davie
These are the price ranges we write on actual Davie estimates for ECO Window Systems custom and geometric work:
| Scenario | Typical Range |
|---|---|
| Standard geometric sash replacement (triangle, trapezoid, octagon) | $1,800 - $3,200 |
| Arched or radius-top full-frame replacement | $2,800 - $4,600 |
| Oversized custom picture unit (over 60″ × 96″) | $4,200 - $6,400 |
| Impact-rated geometric with laminated glass | Add $800 - $1,400 to base |
| Stucco return repair and reframing | $600 - $1,200 additional |
What moves the price: shape complexity (each radius or angle adds fabrication time), glass specification (impact-rated laminated vs. standard IG), and whether the existing frame can be preserved. Full-frame replacement in Davie’s older construction is common; we tell you during the survey, not during the install.
Call (754) 254-8492 for your measured survey. Estimates are free, and the price we write is the price you pay.
Why Davie Homeowners Call Sightline Windows & Doors Davie for ECO Window Systems Work

We’ve installed and serviced ECO Window Systems products in Davie long enough to know which series used which corner joint, which gaskets are still available, and which have been superseded by a design that doesn’t quite match. When an ECO line is discontinued, we don’t guess at a substitute; we pull the original performance spec and match it from our other seven verified manufacturer lines.
Haven Clause 3 means the technician at your door is background-checked, uniformed, and identified by license number before arrival. Haven Clause 4 means you get a photo record of every visit. And the 365-Day Done Right Promise isn’t a courtesy we extend; it’s stamped on every job under the Haven Standard that has governed every one of our 18,000+ openings since 2012.
Sonia Raman, our owner, started in this trade at Los Angeles Trade-Technical College and spent two decades working through every phase of installation before bringing that practice to Davie. Her habit is to measure twice before ordering anything. Measure it right the first time. Everything else follows from that.
FAQs
No. As an independent ECO Window Systems service provider, we perform warranty-safe work using OEM or specification-matched parts. We document every part source in your written scope so your records stay clean. If your ECO unit is still under manufacturer warranty, we note that in our assessment and advise whether the repair is better routed through ECO directly. Call (754) 254-8492 and we’ll review your situation at no charge.
Custom ECO geometric units typically fabricate in 4-6 weeks, with arched and radius-top shapes often at the shorter end and multi-angle polygons at the longer. We don’t quote faster than the factory can deliver; instead, we confirm the production schedule in writing during the survey and update you if it shifts. Call (754) 254-8492 to check current lead times for your specific shape.
We repair when the frame is sound and only the sash, hardware, or seal has failed. We replace when the frame is racked, the series is discontinued with no matched equivalent, or the glass specification no longer meets current Davie wind-borne debris requirements. We make that determination during the measured survey and tell you which path costs less over the unit’s remaining life. Call (754) 254-8492 for an honest assessment.
We stock common ECO hardware and gaskets for active series. For discontinued lines or custom geometric shapes, we order OEM or specification-matched parts from our verified manufacturer network. We don’t install unverified aftermarket components on impact-rated units because we can’t document their performance. The source of every part goes in your written scope. Call (754) 254-8492 to confirm availability for your series.
We match the performance specification from our other verified lines - PGT, CGI, CWS, ES Windows - and document the equivalent U-factor, SHGC, and impact rating in your written scope. We’ve done this for Davie homeowners with early ECO architectural lines where the original extrusion is no longer produced. The replacement meets or exceeds the original spec, and we note any visual difference before you approve. Call (754) 254-8492 for a free second opinion on any written estimate you already have.
