1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

ECO Window Systems Custom & Geometric Windows in North Miami: What to Know First
We provide independent ECO Window Systems custom and geometric window service across North Miami, with most measured surveys scheduled within 48 hours and written pricing delivered before any work begins. Typical custom ECO Window Systems installations run $1,800 to $4,500 per opening depending on shape complexity and impact rating, and we stock no inventory - every unit is ordered to the measured survey we complete together. This page is for North Miami homeowners who already have ECO Window Systems products and need arched, curved, geometric, or oversized replacement windows that match existing sightlines. Call (786) 706-0468 to schedule your free measured survey.
How ECO Window Systems Products Fail - and How We Fix Them

- ECO 5500 Series fixed geometric units: The thermal-break aluminum frame separates at the miter joints after repeated exposure to North Miami’s salt-laden northeast winds, especially in waterfront properties near Biscayne Bay. We see this as a sightline shift - the glazing bead no longer sits flush. Our fix: remove the unit, re-weld the frame corner with matching alloy, and reinstall with new setting blocks sized to the original glazing schedule.
- ECO impact-rated custom shapes with laminated glass: Delamination at the glass edge where the PVB interlayer meets the frame, caused by South Florida’s UV index and the thermal cycling of dark exterior finishes. The symptom is a foggy perimeter that doesn’t wipe clean. We source replacement laminated glass through ECO’s certified fabricator network, never cutting corners with non-rated substitutions that void the Miami-Dade NOA.
- ECO arched-top casements in the 7000 Series: Hinge sag on radius-top units because the weight distribution of the curved sash exceeds the standard hinge set’s load rating. Homeowners notice the sash drifts open or the lock points don’t align. We upgrade to heavy-duty stainless steel hinges with a higher moment capacity, matched to the specific radius and sash weight.
- ECO oversized fixed picture windows: Seal failure in the insulating glass unit, showing as condensation between panes that never clears. In North Miami’s high-humidity climate, this accelerates once the primary seal degrades. We measure the exact glass thickness and spacer specification, then order a direct replacement from ECO’s glass partner - no guesswork on the low-E coating placement.
- ECO geometric mulled combinations: Water intrusion at the mullion joint where a rectangular unit meets a trapezoid or triangle, common in 1980s North Miami retrofits with original aluminum construction. The cause is often capillary break failure at the mullion splice. We disassemble the combination, install a new composite thermal break mullion with end dams, and seal with Sika or Tremco compatible with ECO’s finish warranty.
Before
AfterOur ECO Window Systems Custom & Geometric Windows Process
- 1
Measured survey you keep. Sonia Raman or a verified crew member arrives with a printed license number, measures every rough opening twice, and records frame squareness, plumb, and sightline alignment. You receive this document before we leave.
- 2
Written scope and price. We specify the exact ECO Window Systems series, glass package, and hardware finish. The quote and the survey are the same document - Haven Clause 1. No verbal ranges.
- 3
Parts decision documented. For warranty-active units, we use OEM ECO components. For out-of-warranty work, we may specify quality aftermarket equivalents from our verified supply chain, with the trade-off noted in writing.
- 4
Fabrication and delivery. Custom ECO units typically ship from their Hialeah Gardens fabrication facility in 4 to 6 weeks. We coordinate delivery to your North Miami address and inspect every unit against the survey before scheduling installation.
- 5
Installation and testing. Crew sets the unit, checks operation, verifies lock engagement, and photographs the completed opening. The photo record uploads to your job file by end of day.
- 6
365-Day Done Right Promise activated. The written warranty and photo documentation are delivered. If the sightline shifts or the seal fails, we make it right - no renegotiation.

Impact-rated glass adds $400 to $700 per opening over non-impact. North Miami’s proximity to ECO’s Hialeah Gardens facility reduces freight compared to Broward or Palm Beach jobs, and we pass that through. Call (786) 706-0468 for your exact written price - estimates are free.
Why North Miami Homeowners Call Sightline Windows & Doors North Miami for ECO Window Systems Work
We are independently owned and operated under the Haven Standard, not a franchise, and we have measured, ordered, and set ECO Window Systems units across North Miami since the brand entered the South Florida market. Our crew includes technicians who have worked the Biscayne corridor retrofits - the ones with aging aluminum frames that taught us more about frame fatigue than any product manual. When ECO lead times extend or a series discontinues, we pivot to PGT, CGI, CWS, or ES Windows with matching performance specs, because we specify by what the opening requires, not by what is in stock. Every tech is background-checked, uniformed, and identified by license number before arrival. The 365-Day Done Right Promise is stamped on every job, not offered as a courtesy. Measure once, document everything, explain the rest in plain English.
FAQs

No - as an independent ECO Window Systems service provider, we use OEM parts for warranty-active units and document every component serial number. The warranty remains intact because we do not alter the original engineering; we replace like-for-like with ECO-certified components. Call (786) 706-0468 if you need us to verify your warranty status before scheduling.
Standard lead time is 4 to 6 weeks from measured survey to delivery at your North Miami address. Complex radius work or oversized glass can extend to 8 weeks. We quote the lead time in writing on the same document as the price, so you know before ordering. Call (786) 706-0468 to check current ECO fabrication schedules.
Yes - ECO maintains color formulas for their standard and custom paint options, including the coastal whites and bronzes common in North Miami’s 2000s construction. We order finish samples for your approval before fabrication. If your original finish has faded unevenly due to South Florida UV exposure, we note the variance in writing so you can decide on full replacement or closest match.
Repair makes sense when the frame is sound and only the glass or hardware has failed. Replacement is the better path when the frame shows corrosion at the weep holes, the thermal break has separated, or the original unit was non-impact and you now need Miami-Dade HVHZ compliance. We document both options with written prices and let the numbers guide the decision. Call (786) 706-0468 for a free second opinion on any estimate.
Yes - we pull the permit, schedule inspection, and pass the certificate to you. North Miami requires permits for all window replacements in HVHZ zones, and geometric or custom units trigger additional structural review when they exceed standard rough opening tables. We handle the submittal drawings and NOA documentation as part of our scope. Call (786) 706-0468 to confirm permit requirements for your specific project.
