ES Windows Custom & Geometric Windows in Lantana: What to Know First
We install and replace ES Windows custom and geometric units in Lantana as an independent ES Windows service provider. A typical custom or shaped window project runs two to four weeks from measured survey to final installation, depending on glass tempering and framing complexity. The price we write on your quote is the price on your invoice - Haven Clause 1, no exceptions.
This page is for Lantana homeowners who already own ES Windows products and need arched, curved, oversized, or geometrically shaped units replaced or newly installed. You might live in a 1980s ranch near Hypoluxo Island with original radius-top windows, or a newer build along Ocean Avenue where the architect specified ES Windows custom impact units. Either way, you want the model number, the U-factor, and the installed price in writing before anyone touches your opening. Call (561) 461-2062 to schedule your free measured survey.
How ES Windows Products Fail - and How We Fix Them
- ES Windows 8100 Series fixed geometric units: The thermal break in the 8100’s extruded aluminum frame separates at the weld corners on radius-top and hexagonal configurations after five to seven years of Lantana’s salt-air exposure. We see this most often on east-facing gables where morning sun hits cool metal. Our fix is a full frame replacement with marine-grade corner brackets and a butyl tape seal that outlasts the OEM foam gasket.
- ES Windows 5500 Series operable arched units: The scissor hinge on the 5500’s casement-style geometric windows binds when the sash weight exceeds 45 pounds, which happens on any arched unit wider than 36 inches. The factory hinge isn’t rated for the leverage of a curved sash. We replace with a heavy-duty Truth Hardware hinge set, or spec the 6500 Series upgrade if the opening allows.
- ES Windows custom laminated impact glass: Delamination at the PVB interlayer shows as a hazy perimeter ring, usually starting at the bottom of oversized units where condensation collects. ES Windows’ standard warranty covers this for ten years, but only if the installation documentation shows proper shimming and drainage. We photograph every shim placement so your warranty claim holds up.
- ES Windows oversized fixed picture units: Sagging at the center of spans over 72 inches wide, especially in the 4100 Series non-impact line. The mullion reinforcement spec’d from the factory is a 2-inch box beam; we upgrade to a 3-inch engineered mullion on any unit over 60 inches, documented in your written scope before we order.
- ES Windows geometric vinyl line (discontinued 2019): Color fade and chalking on the capstock, worst on south and west exposures in Lantana’s UV index. ES Windows no longer stocks matching extrusions. We either source neutral-toned aftermarket cladding that blends with faded originals, or quote a full replacement in the current aluminum line with the finish you choose.
Our ES Windows Custom & Geometric Windows Process

- 1
Measured survey. We arrive with a laser measure, a level, and a camera. You keep the handwritten field notes. We record rough opening dimensions, squareness to 1/16 inch, and existing frame condition. If it’s an ES Windows unit, we photograph the label stamp for model, size, and glass spec.
- 2
Diagnosis and scope. We determine whether your opening needs OEM ES Windows parts, quality aftermarket hardware, or a full unit replacement. For discontinued lines, we show you the aftermarket option and the replacement option, both priced.
- 3
Written quote. The measured survey becomes your quote. Every line item carries a unit price: frame, glazing, hardware, labor, disposal. Haven Clause 1 - the quote and the final invoice are the same document.
- 4
Fabrication and delivery. Custom ES Windows units ship from their Florida facility in three to four weeks; geometric glass tempering adds five to seven days. We confirm delivery before we schedule install.
- 5
Installation and testing. Our crew installs per ES Windows’ published installation instructions, not shortcuts. We operate every moving part, check the sightline for square, and run a water spray test on impact-rated units.
- 6
Documentation and closeout. You receive the photo record, the completed warranty card, and the invoice that matches your quote. The 365-Day Done Right Promise is stamped and dated.

Why Lantana Homeowners Call Sightline Windows & Doors Lantana for ES Windows Work

We’ve logged work on homes from the beachfront corridor along Ocean Avenue to the inland neighborhoods near Lantana Community Middle School, and the pattern is consistent: ES Windows units in Lantana fail at the corners, the hinges, and the seal - not the glass. Our techs know which series uses which extrusion, which hardware is still available, and which upgrades are worth the cost.
The Haven Standard governs every job. Verified crews with license numbers on the page. A written price before any work starts. A documented photo record when it’s done. And if something’s not right, the 365-Day Done Right Promise means we make it right - not as a favor, but as a clause.
We also specify PGT, CGI, CWS, and ECO Window Systems when the opening calls for a different performance tier or price point. Eight lines, chosen by what your wall needs, not by what our warehouse holds.
Measure it right the first time. Everything after that is just paperwork.
FAQs
No, if the repair uses OEM parts and follows ES Windows’ published installation instructions. We photograph every step and keep the parts invoice so your warranty documentation is complete. Call (561) 461-2062 if you need a warranty-safe repair assessed.
Three to four weeks for the frame, plus five to seven days for tempered or laminated geometric glass. We don’t schedule demolition until the unit is in our warehouse, so your opening is never open overnight. Call (561) 461-2062 to check current lead times.
Yes for current ES Windows color lines; for discontinued finishes, we source the closest aftermarket match or quote a full opening replacement in your choice of finish. We bring physical samples to the measured survey so you see the match before we order. Call (561) 461-2062 to schedule.
Repair makes sense when the frame is sound and only the glass or hardware has failed. Replacement is the better value when the frame shows corrosion, the thermal break is compromised, or the unit is a pre-2019 vinyl line with no available extrusions. We give you both prices and our recommendation, no pressure. Call (561) 461-2062 for a free second opinion on any written estimate.
Yes, for any replacement that changes the rough opening or any new installation. We handle the permit application, the inspection scheduling, and the final sign-off. The permit cost is listed as a line item on your written quote, not added later. Call (561) 461-2062 to confirm permit requirements for your specific project.
