ECO Window Systems Custom & Geometric Windows in Lantana: What to Know First
As an independent ECO Window Systems service provider in Lantana, we measure, fabricate, and install custom and geometric windows from ECO’s product lines with written pricing before any work begins and a 365-Day Done Right Promise stamped on every job. Most ECO custom and geometric window projects in Lantana run between $1,200 and $4,800 per opening depending on shape complexity, impact rating, and whether the rough opening needs reframing. We carry the full ECO Window Systems catalog alongside PGT, CGI, CWS, and ES Windows, so if a curved or arched specification isn’t optimal from one line, we specify from another without margin pressure.
This page is for Lantana homeowners who already own ECO Window Systems products or are specifying them for new custom openings, coastal remodels, or geometric replacements in homes along the beachfront corridor where salt air and wind-borne debris are annual realities. Call (561) 461-2062 to schedule your free measured survey. The document we leave with you becomes your written quote; the two cannot differ.
How ECO Window Systems Products Fail - and How We Fix Them
- ECO 9000 Series arched tops: seal decompression in the curved jamb. The 9000’s thermal-break design uses a co-extruded gasket path that can separate at the radius transition after three to five Lantana summers of UV cycling and salt-air oxidation. We see this on ocean-facing second stories where the arch catches morning sun. Our fix: we pull the sash, document the seal geometry with photos, and order the radius-specific replacement from ECO’s Miami distribution center. We do not field-bend standard gaskets; the tolerance stack on an arched unit won’t allow it.
- ECO 5000 Series geometric shapes: corner weld stress cracking on trapezoids and pentagons. The 5000 line uses a corner fusion process that holds well on rectangles but can cold-flow on acute angles below 45 degrees. In Lantana, thermal expansion from afternoon concrete wall mass accelerates the fatigue. We specify reinforced internal gussets on replacement units and verify the weld penetration with a borescope before installation. Haven Clause 4: evidence on every job.
- ECO impact-rated custom units: laminated glass delamination at the edge bite. ECO’s impact laminates use SentryGlas or PVB interlayers depending on the year of manufacture; pre-2019 units with PVB can show edge fogging when the primary seal fails and Lantana humidity reaches the glass perimeter. We date-code the existing unit from the etched mark in the corner, match the interlayer type, and replace the whole insulated glass assembly rather than attempting a field repair that voids any remaining warranty.
- ECO oversized custom openings: sash drop on units over 72 inches wide. The hardware specification on ECO’s wide-format custom line sometimes ships with standard friction stays where heavy-duty cam handles are required for the sash mass. We measure the actual sash weight on a digital scale during survey, then specify the correct ECO hardware kit by part number. This is a specification error, not a product defect, but it shows up on Lantana homes with the 8-foot openings popular in 2016-2019 construction.
- ECO curved and radius windows: frame twist from improper shimming at original install. Curved ECO units have a neutral axis that must sit plumb; if the original installer shimmed the sill plane without checking the radius centerline, the frame twists and the operable sash binds. We remove the unit, document the rough opening with a laser level and photos, and reinstall with adjustable composite shims at the calculated bearing points. The measured survey you keep shows the before-and-after frame readings.
Our ECO Window Systems Custom & Geometric Windows Process

- 1
Measured survey. Sonia Raman or a verified crew member arrives with a printed license number, measures the rough opening to the sixteenth, and records frame squareness, plumb, and diagonals. You keep this document. Measure it right the first time. Everything after that is just paperwork.
- 2
Product specification. We pull ECO’s current catalog and cross-check against PGT, CGI, CWS, and ES Windows equivalents. If ECO’s lead time or price point doesn’t fit the opening requirements, we name the alternative in writing with U-factor, SHGC, and impact rating for each.
- 3
Written quote. Haven Clause 1: the price is line-itemed by unit, labor, permit, and disposal. No change orders permitted except for concealed structural damage documented with photos.
- 4
Fabrication and delivery. Custom and geometric ECO units ship from Miami; we track the order and inspect at receipt for transit damage to the radius forms or corner welds.
- 5
Installation and testing. We install, shim to the survey spec, seal with backer rod and specified sealant, then operate every sash and document with a photo record showing the sightline alignment and the closed-unit light gap.
- 6
Warranty registration and closeout. We register the ECO warranty in your name, leave the 365-Day Done Right Promise in writing, and archive the photo record under the Haven Standard.

Why Lantana Homeowners Call Sightline Windows & Doors Lantana for ECO Window Systems Work

We’ve logged work on homes along the Lantana beachfront corridor since 2012, where salt air and hard summer storms test every seal and weld. The Haven Standard governs every opening: written price before work starts, verified crews with license numbers on the page, evidence on every job, and no surprises. Our 365-Day Done Right Promise is stamped on every contract, not offered as a courtesy.
We carry eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - and we specify by what the opening requires, not by what is in stock. If ECO’s lead time or specification doesn’t fit, we name the alternative with numbers on the page. Calls are answered by a live person, 24/7. Bring us any competitor’s written estimate; we’ll review it at no charge.
FAQs
No. As an independent ECO Window Systems service provider, we use OEM-specified parts and register the warranty in your name; the warranty remains valid if the installation follows ECO’s published guidelines, which we document with photos. Call (561) 461-2062 if you have a specific warranty concern - we’ll review the terms with you before any work begins.
ECO’s Miami distribution center typically ships custom and geometric units in four to six weeks; radius and complex multi-angle shapes run toward the longer end. We track the order and inspect at receipt for transit damage to welds or radius forms. If your timeline is critical, we can cross-specify from PGT or CGI stock programs with equivalent ratings. Call (561) 461-2062 to discuss lead times for your specific shape.
We repair when the frame is square and the glass edge bite is intact; we replace when the corner weld has cracked through, the thermal break is compromised, or the impact laminate has delaminated. The measured survey determines which path we recommend, and we document the reasoning with photos you receive. Estimates are free - call (561) 461-2062 to schedule.
Yes. Lantana requires permits for all impact-rated window installations and for any replacement that alters the rough opening dimension. We pull the permit, schedule the inspection, and pass it before final payment. The permit number and inspection result are included in your closeout documentation under Haven Clause 4.
It doesn’t, unless we find concealed structural damage - rotted header, termite damage, or non-compliant framing - that we document with photos before any additional work proceeds. Haven Clause 5: no surprises. The written quote from your measured survey is the final invoice unless you approve a documented change order in writing. Call (561) 461-2062 with any pricing question; estimates are free.
