ES Windows Custom & Geometric Windows in Clewiston: What to Know First
We provide independent ES Windows service for custom and geometric windows in Clewiston, with most measured surveys scheduled within two business days and written quotes delivered before any work begins. A typical custom ES Windows installation runs $1,800-$4,500 depending on shape complexity and impact rating, and we stock no inventory - every unit is specified to the opening after we measure it. This page is for ES Windows owners in Clewiston who need arched, curved, or oversized geometric units replaced or installed new, and who want the price in writing before a tool touches their wall. Call (863) 509-1135 to schedule your measured survey.
How ES Windows Products Fail - and How We Fix Them

- ES Windows 5500 Series fixed geometric units: The thermal break in the extruded frame separates at the weld corners on radius-top and quarter-circle configurations, especially where the Clewiston afternoon sun hits the west face. We see this on homes near the U.S. Sugar corridor where there’s no tree buffer. We cut the frame open, re-weld with a reinforced corner key, and re-glaze with the specified silicone structural sealant - not a surface bead that’ll peel in two seasons.
- ES Windows 8000 Series impact-rated custom shapes: The laminated glass delaminates at the curved edge where the interlayer stress concentrates. ES Windows uses a .090 PVB interlayer on most 8000 Series impact units, and the radius cut exposes it to moisture intrusion that starts at the edge and spiders inward. We specify a full glass replacement with the OEM interlayer, not a generic laminated drop-in, because the impact certification depends on the exact lamination stack.
- ES Windows 4000 Series oversized rectangular custom units: The sash warps on spans over 72 inches when the reinforcement chamber isn’t fully packed with galvanized steel. Clewiston’s humidity cycles accelerate the twist. We pull the sash, verify the steel insert is continuous and seated, and replace it if there’s a gap - not shim and hope.
- ES Windows geometric casement operators: The scissor-arm operator on trapezoid and pentagon configurations binds because the factory-set throw angle doesn’t account for real-world sill deflection in older Clewiston block construction. We measure the actual hinge axis under load and spec an aftermarket Truth Hardware operator with adjustable throw, or rebuild the existing arm if the gearing isn’t stripped.
- ES Windows custom window weep drainage: On radius-bottom and eyebrow shapes, the weep channels are drilled at the factory for a flat-sill assumption. Installed on a sloped sill in a Clewiston home built on fill near the lake, water pools and backs up into the track. We re-route the drainage with sloped sill pans and secondary weeps - a detail ES Windows doesn’t address in their installation manual for custom profiles.
Before
AfterOur ES Windows Custom & Geometric Windows Process
- 1
Measured survey. Sonia Raman or a verified crew member arrives with a laser measure, level, and the template set for ES Windows geometric profiles. You keep the measured drawing; it’s the basis for the quote and the final invoice.
- 2
Written price. We specify the exact ES Windows series, glass package, and any aftermarket hardware modifications. The price you sign is the price on the invoice - Haven Clause 1.
- 3
Parts decision. For warranty-active units under ten years, we quote OEM glass and extrusions. For older units or discontinued profiles, we source quality aftermarket equivalents and document the substitution in writing.
- 4
Fabrication coordination. ES Windows custom geometric units ship from their Florida facility in 4-6 weeks for standard shapes, 6-8 weeks for complex multi-radius designs. We coordinate delivery to avoid storage damage.
- 5
Installation and testing. Crew arrives uniformed, license number provided in advance per Haven Clause 3. We install, operate every moving part, check the sightline for square, and photograph the completed work.
- 6
Documentation and promise. You receive the photo record, the completed scope document, and the 365-Day Done Right Promise - if it’s not right, we make it right.
What ES Windows Custom & Geometric Windows Costs in Clewiston

| Scenario | Typical Range |
|---|---|
| Standard geometric replacement (arched top, fixed, non-impact) | $1,800 - $2,800 |
| Impact-rated custom shape (5500 or 8000 Series, laminated glass) | $2,800 - $4,200 |
| Oversized custom rectangle (4000 Series, 72″+ span, with reinforcement) | $3,200 - $4,500 |
| Complex multi-radius or eyebrow shape, impact-rated | $4,000 - $6,500 |
| Operator/hardware rebuild on existing geometric casement | $340 - $580 |
What moves the price: impact rating versus non-impact, glass thickness (5/16″ versus 7/16″ laminated), whether the rough opening needs reframing for square, and whether we can reuse the existing ES Windows subframe or must fabricate a new one. We don’t estimate from photos; we measure in person. Call (863) 509-1135 for your written estimate - there’s no charge for the survey.
Why Clewiston Homeowners Call Sightline Windows & Doors Clewiston for ES Windows Work
We’ve installed and serviced ES Windows products in Clewiston long enough to know which series shipped with the undersized corner keys and which years had the weep routing issue. When ES Windows discontinues a profile, we maintain cross-reference sheets to match PGT, CGI, CWS, or ECO Window Systems equivalents that’ll fit the existing rough opening without reframing. Every technician is background-checked and uniformed; you get their license number before they arrive. The 365-Day Done Right Promise is stamped on every job, not offered as a favor. And if you’ve got a competitor’s written estimate, we’ll review it free - Haven Clause 1 applies to second opinions too.
FAQs

No - ES Windows’ product warranty covers manufacturing defects regardless of who installs or services the unit, provided the work doesn’t alter the frame or glass specification. As an independent ES Windows service provider, we document every part number and sealant type so your warranty claim stays clean if a factory defect appears later. Call (863) 509-1135 if you need help determining whether a failure is installation-related or manufacturing-related.
Standard shapes from ES Windows’ Florida facility typically ship in 4-6 weeks; complex multi-radius or oversized units run 6-8 weeks. We don’t quote faster than the factory can fabricate, and we don’t substitute a stock unit to hit a deadline. The measured survey includes the confirmed lead time in writing.
Yes, if the profile is still active. ES Windows uses a proprietary Kynar paint system with coded lot numbers. We pull the extrusion code from your existing frame and spec the same color formulation. On discontinued colors, we provide a physical sample for your approval before fabrication - no surprises at install.
Replace if the frame is warped, the thermal break is separated at multiple corners, or the glass delamination exceeds two inches from the edge - these are structural failures that repairs won’t hold. Repair if the issue is isolated to hardware, weatherstripping, or a single-point seal breach. We tell you which category you’re in at the measured survey, with the price for both paths. Call (863) 509-1135 to schedule.
Yes, for all impact-rated replacements and any new opening creation. Hendry County requires permits for impact-rated window work; we pull them, schedule inspections, and pass them - documented in your photo record. Non-impact replacement-in-kind typically doesn’t trigger permitting, and we’ll tell you if yours qualifies.
Call (863) 509-1135 to schedule your free measured survey and written estimate for ES Windows custom and geometric windows in Clewiston. Measure it right the first time. Everything after that is just paperwork.
