ECO Window Systems Custom & Geometric Windows in Tamiami: What to Know First

We install and replace ECO Window Systems custom and geometric windows across Tamiami as an independent service provider, not an authorized dealer. Most custom ECO Window Systems orders in this market run 4-6 weeks from measured survey to installation, with written pricing locked at survey and no change orders after signing. Typical custom and geometric window projects in Tamiami fall between $1,800 and $4,200 per opening depending on shape complexity, impact rating, and whether the rough opening needs reframing.

How ECO Window Systems Products Fail - and How We Fix Them

• ECO Window Systems Architectural Series arched tops: seal failure in the curved sash. The thermal break in the extruded frame separates at the radius point where the arch meets the jamb, accelerated by Tamiami’s UV load and the expansion cycling from afternoon storms. We see this most in west-facing elevations along Tamiami Trail where the glass runs hot. We order OEM replacement sashes with the upgraded dual-durometer seal ECO Window Systems introduced in 2019, or fabricate a matching radius sash from CWS or ES Windows stock if the line has been discontinued.
• ECO Window Systems custom octagon and hexagon units: corner joint weeping. The mitered corners on geometric shapes rely on a two-part structural epoxy that degrades when standing water sits in the bottom rail. In Tamiami’s flat-roof additions and Florida room retrofits, these shapes often sit beneath scuppers or gutter overflows. We disassemble the corner, clean the old epoxy with MEK, and re-bond with SikaFlex-252 after confirming drainage path clearance. If the glazing bead is OEM-only, we source it direct; if not, we match from our PGT or CGI geometric inventory.
• ECO Window Systems oversized fixed picture units: sagging at the center stile. Custom widths over 72 inches without a mullion sometimes develop a visible bow in the intermediate horizontal, particularly on second-story installations where the wall framing has settled. We measure the deflection with a straightedge and laser, then spec either a reinforced thermal break insert or split the opening with a matching custom mullion from the ECO Window Systems catalog. When ECO Window Systems lead times stretch past eight weeks, we engineer an equivalent from ES Windows’ custom line with matching sightlines.
• ECO Window Systems impact-rated custom shapes: laminated glass delamination at the edge. The polyvinyl butyral interlayer in impact laminates can separate when the glass edge sits in a wet pocket, common in Tamiami’s older CBS construction where the stucco weeps into the rough opening. We document the delamination extent with edge-lit photography, then replace with fresh laminated stock cut to the original ECO Window Systems pattern - never grinding down a standard rectangle to fit a geometric shape, which voids the NOA.
• ECO Window Systems radius top mulled to rectangular below: water intrusion at the marriage joint. The transition between curved and straight framing is the most leak-prone detail we find in Tamiami custom installations. The factory mull cap often arrives with a generic spline that doesn’t account for local stucco thickness or the radius-to-straight geometry change. We field-fabricate a transition flashing from .040 aluminum, sealed with Dow 795, and photograph the assembly before closing the wall. This detail is not in ECO Window Systems’ standard install manual; we developed it from repeated callbacks on other contractors’ work in the Fontainebleau and Westchester areas.

Our ECO Window Systems Custom & Geometric Windows Process

1. 1
   Measured survey you keep. Sonia Raman or a verified crew member arrives with a printed license number, measures every rough opening to 1/16 inch, notes wall plumb and squareness, and records frame readings for U-factor and SHGC. You receive this document before we leave.
2. 2
   Written scope and price. Haven Clause 1: the quote matches the survey exactly. We specify ECO Window Systems model, glass package, hardware finish, and any reframing. The price is fixed. No change orders.
3. 3
   Parts decision documented. If your ECO Window Systems series is active, we order OEM. If discontinued, we identify the closest match from our eight manufacturer lines and note the deviation in writing before you approve.
4. 4
   Installation with photo record. Verified crew, uniformed, license number confirmed. We photograph rough opening condition, flashing details, and final sightline alignment. Evidence on every job, Haven Clause 4.
5. 5
   Final test and 365-Day Done Right Promise. Operate every sash, check every lock, verify weep path drainage. The written warranty and photo record upload to your file. If it’s not done right, we make it right.

We are independently owned and operated under the Haven Standard, not a franchise, and we have measured, ordered, and installed ECO Window Systems products in the neighborhoods abutting Tamiami Trail since the line first entered South Florida distribution. Sonia Raman grew up in Miami, trained at Miami Lakes Educational Center, and has done replacement work near the Miccosukee Resort corridor more times than she can count. Her crew reads a rough opening correctly the first time and orders product that matches Miami-Dade NOA requirements before a permit question ever comes up.

When ECO Window Systems lead times stretch or a series discontinues, we pivot to equivalent spec from PGT, CGI, CWS, or ES Windows without restarting your timeline. The 365-Day Done Right Promise covers every installation. The photo record proves what was done. And the written price you received at survey is the price on the final invoice - no exceptions since 2012.
