ECO Window Systems Custom & Geometric Windows in North Palm Beach: What to Know First
As an independent ECO Window Systems service provider in North Palm Beach, we measure, quote, and install custom and geometric windows from ECO’s catalog with written pricing before any work begins and a 365-Day Done Right Promise stamped on every job. Most ECO Window Systems custom and geometric window projects in North Palm Beach run four to eight weeks from measured survey to final installation, depending on glass tempering schedules and whether the opening needs structural correction. We do not quote over the phone; Haven Clause 1 requires that the measurement and the written price travel together as the same document.
This page is for homeowners who already own ECO Window Systems products or are specifying them for a new custom or geometric window installation - arched tops, circular fixed units, trapezoids, or oversized openings that standard catalogs cannot accommodate. If your opening isn’t right, the window isn’t right - that’s where we start. Call (561) 475-1246 to schedule your measured survey; the written estimate is free and you keep the document.
How ECO Window Systems Products Fail - and How We Fix Them
- ECO ES 8000 Series fixed geometric units: The thermal break in the aluminum frame separates at the weld corners on radius-top installations, especially where the North Palm Beach sun loads the south-facing elevation daily. We see this most in Lakeside Park homes with 1980s concrete-block construction where the rough opening settled after original install. We remove the unit, re-machine the frame corners with OEM thermal-break inserts, and re-glaze with the correct structural silicone rather than the butyl tape some retro-fitters use.
- ECO impact-rated custom shapes (ES-C Impact line):strong> Laminated glass delamination at the curved cut edge, visible as a white haze spreading from the perimeter of circular or arched units. This happens when the glass supplier uses a cold-cutting process on low-iron laminate instead of the heat-soaked edge treatment ECO specifies. We source replacement IGUs only from ECO-certified fabricators who document their heat-soak protocol, and we photograph the edge seal before installation per Haven Clause 4.
- ECO oversized fixed units (ES 6000 Series, non-impact): Sash sag on units wider than 60 inches where the reinforcing steel mullion was omitted or undersized at original install. The tell is a diagonal crack in the interior drywall at the head jamb. We open the wall, sister the existing steel or install a new engineered mullion per ECO’s span table, and reset the unit on composite shims that won’t compress like the pine shims we find in older North Palm Beach work.
- ECO geometric casement units with integral screens: Screen frame warp on trapezoidal and triangular configurations, caused by ECO’s standard .020 aluminum screen extrusion being stretched during field cutting to match the slope. The screen then bows away from the sash, admitting insects and trapping debris. We fabricate replacement screens on-site with .025 extrusion and mitered corners rather than the factory’s butt-joint method, and we document the gauge change on the work order.
- ECO coastal bronze anodized finishes on custom units: Chalk and fade within seven to ten years on west and south elevations, accelerated by the salt-air exposure that starts at the Intracoastal and worsens toward the ocean. ECO’s standard anodize is Class I (0.7 mil), which is sufficient for inland Florida but marginal for North Palm Beach’s salt-spray zone. We specify Class II (1.0 mil) or Kynar 500 paint finish on replacement units, note the upgrade on the written quote, and show the customer the finish warranty differential - 10 years versus 20 years.
Our ECO Window Systems Custom & Geometric Windows Process

- 1
Measured survey. Sonia Raman measures every opening herself on the first visit. She documents rough opening width, height, squareness, and plumb with a digital level and laser; the customer keeps this survey. For geometric units, she also records the springline height on arches and the included angle on trapezoids.
- 2
Written quote. Haven Clause 1: the quote cannot differ from the measured survey. We specify the ECO series, glass package, finish, and any structural correction required. The customer signs and keeps a copy before any deposit.
- 3
Fabrication oversight. For custom ECO units, we review the shop drawings from the fabricator against our field measurements before release to production. On one Lakeside Park retrofit, this caught a 3/8-inch springline discrepancy that would have left a daylight gap at the head.
- 4
Installation with documented evidence. Background-checked, uniformed technicians arrive with license numbers visible. They install per ECO’s published installation guidelines, not field shortcuts. Haven Clause 4 requires photographs of the rough opening, the shimming, the sealant application, and the finished unit from inside and out.
- 5
Operational test and final walk. Every operable unit is cycled twenty times. Every fixed unit is inspected for sealant continuity and drainage path clearance. The customer receives the photo record, the completed warranty registration, and the 365-Day Done Right Promise in writing.
- 6
Follow-up at 90 days. We call to confirm the unit has settled through its first thermal cycle season in North Palm Beach’s humidity. If adjustment is needed, we schedule it under the Promise at no charge.

What moves the price: glass package (impact versus non-impact, low-E coating, tint), finish upgrade (standard anodize to Class II or Kynar), structural work to the opening, and accessibility (second-story with ladder versus scaffold). We do not change the price after the written quote is signed unless you change the scope. Call (561) 475-1246 for your measured survey and written estimate - both are free.
Why North Palm Beach Homeowners Call Sightline Windows & Doors North Palm Beach for ECO Window Systems Work

We are not the only installer who carries ECO Window Systems in North Palm Beach. We are the only one who operates under the Haven Standard: Have it in writing, Arrive on schedule, Verified crews, Evidence on every job, No surprises. The 365-Day Done Right Promise is not a courtesy we extend; it is stamped on every job because it is Haven Clause 5.
Sonia Raman learned the trade at Miami Lakes Educational Center’s building construction technology program before she touched a finished frame on a job site. She has logged years of work in North Palm Beach, including the retrofit projects in Lakeside Park where older concrete-block homes needed full rough-opening corrections before a single new ECO unit could go in. She still measures every opening herself on the first visit because she has seen what a quarter-inch assumption costs in lead time and money.
When ECO lead times stretch or a specific series discontinues, we specify from our other verified lines - PGT, CGI, CWS, ES Windows - by performance tier and price range, not by margin. The written quote names the manufacturer, the series, the U-factor, and the SHGC. You know what you are buying before you buy it.
FAQs
No, provided the installation follows ECO’s published guidelines and uses OEM or ECO-approved components. As an independent ECO Window Systems service provider, we register every installation with ECO’s warranty department and include the registration confirmation in your documentation package. Call (561) 475-1246 and we will review your existing warranty status before quoting.
Typically four to six weeks from shop drawing approval, plus one to two weeks for tempered or laminated glass scheduling. Arched and circular units with heat-soaked edges add three to five days. We do not quote delivery dates we cannot document; your written quote includes the fabrication schedule. Call (561) 475-1246 to start the measured survey.
We can match within the tolerances ECO publishes for each finish generation. Coastal bronze anodize from 2010-2015 differs slightly from current stock due to chemistry changes; we note this on the quote and provide a physical sample before fabrication. Kynar 500 paint matches are exact per the manufacturer’s batch record. Call (561) 475-1246 to schedule a finish comparison.
Replace if the frame is thermally broken or the glass is delaminated; repair if the issue is sealant, hardware, or screen. On units over fifteen years old in North Palm Beach’s salt-air environment, we typically recommend replacement because the frame finish is nearing its service life and the glass technology has improved measurably. We document both options in writing with a ten-year cost projection. Call (561) 475-1246 for the analysis.
Yes, for every job that requires one under Palm Beach County building code. Custom and geometric windows in impact zones always require a permit and final inspection. We pull the permit, schedule the inspections, and include the permit number on your written quote. The cost is listed as a line item; it is not buried in overhead. Call (561) 475-1246 to confirm permit requirements for your specific opening.
