ES Windows Custom & Geometric Windows in Weston: What to Know First

We install and replace ES Windows custom and geometric units in Weston as an independent ES Windows service provider, with most measured surveys scheduled within 48 hours and written prices delivered before any work begins. Custom shapes - arched tops, trapezoids, oversized fixed picture units - typically run 3-5 weeks from signed quote to installation, depending on glass specification and ES Windows’s current production queue. We do not quote over the phone; Haven Clause 1 requires a measured survey we hand you to keep, and that document becomes the written scope.

This page is for Weston homeowners who already know they want ES Windows and need someone who can specify the right series, measure complex geometry without rounding, and install to the manufacturer’s required tolerances. Call (754) 812-9260 to schedule your measured survey.

How ES Windows Products Fail - and How We Fix Them

• ES-5000 Series arched tops: seal decompression at the springline curve. The thermal break in ES Windows’s ES-5000 line can separate at the apex of an arch where the extrusion is stress-formed, not bent. We see this in Weston on west-facing elevations where daily expansion cycles are aggressive. Our fix: we order the replacement sash with the arch pre-formed at ES Windows’s factory, never field-modified, and we verify the new unit’s thermal-break continuity with a borescope before accepting delivery.
• ES-8000 Impact geometric units: corner delamination in salt-air exposure. The laminated glass in ES-8000 impact-rated shapes can fog at the miters when the interlayer pulls from the edge seal. Weston homes near the Town Center corridor and Bonaventure catch more salt-laden air than inland parcels, and the corner geometry concentrates the stress. We replace with OEM-spec laminated glass, not aftermarket laminates, because ES Windows’s interlayer-to-glass adhesion is proprietary and third-party laminates void the impact certification.
• ES-6000 oversized fixed picture windows: sill pan deflection under span. ES-6000 units over 72 inches wide can develop a low spot at center sill when the rough opening isn’t dead flat, which channels water to the middle instead of the weeps. We find this on Weston homes built in the 2005-2010 wave where framing dried unevenly. Our fix: we shim the sill pan to 1/4 inch per foot minimum slope before the unit goes in, and we document the level reading in your photo record.
• ES-4000 trapezoid and pentagon shapes: operator misalignment in awning configurations. The scissor hinge on ES-4000 awning operators was revised in 2019; pre-2019 hardware drifts out of square on non-rectangular sashes because the hinge geometry assumes parallel jambs. We stock both hinge generations, verify the production date from the NFRC label, and replace like-for-like or upgrade to the revised bracket set when the old geometry is no longer available.
• ES-7000 curved head radius windows: glazing bead shrinkage in high-UV exposure. The flexible PVC glazing bead on ES-7000 radius units hardens and pulls away from the curve after 6-8 years of south Florida sun. We see this on Weston homes with pool enclosures that reflect UV upward onto the lower sash. We replace with ES Windows’s current EPDM-compatible bead, which has better UV stabilization, and we note the exposure condition in your file for future service reference.

Our ES Windows Custom & Geometric Windows Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives with a printed license number, measures every opening from three reference points, and records frame squareness, sill level, and exposure conditions. You keep the survey.
2. 2
   Series verification and parts decision. We photograph the NFRC label and any existing damage, then determine whether OEM ES Windows parts are available or whether a quality aftermarket equivalent meets the specification without voiding remaining warranty coverage.
3. 3
   Written quote. The quote references the survey document by date and signature; the price cannot change unless you change the scope. No verbal estimates. No “we’ll see when we get into it.”
4. 4
   Installation to ES Windows tolerances. We set the unit plumb, level, and square within 1/8 inch, seal with manufacturer-specified backer rod and sealant, and verify operation before cleanup begins.
5. 5
   Documented photo record and testing. You receive dated photos of the installation, the level readings, and the final operation test. This is standard, not an upsell.
6. 6
   365-Day Done Right Promise activation. The job enters our system under Haven Clause 5: if it’s not done right, we make it right. The promise is written, not verbal.
