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

We provide independent ES Windows service for custom and geometric windows in Kendall, with most measured surveys scheduled within two business days and written quotes delivered before any work begins. Typical custom geometric installations run $2,800-$7,500 depending on shape complexity, impact rating, and opening size. We do not quote over the phone for ES Windows geometric work; the measurement and the quote are the same document, and both require a site visit.

This page is for Kendall homeowners who already own ES Windows products and need custom-shaped replacements, arched transoms, circular accent windows, or oversized geometric openings that standard catalog sizes will not fit. If your ES Windows frames are showing seal failure, your curved top sash has settled out of square, or your builder-grade geometric unit was never impact-rated to begin with, we can specify, measure, and install the correct replacement. Call (786) 321-3319 to schedule your measured survey.

How ES Windows Products Fail - and How We Fix Them

• ES Windows 8100 Series geometric transoms: The arched top rail in the 8100 Series uses a welded PVC corner key that stress-cracks after four to six years of Kendall’s thermal cycling. We see this most often in Dadeland-area townhomes where the transom sits above a west-facing slider. Our fix is a full sash replacement with a heat-welded reinforcement plate at the arch apex, not a surface patch that will reopen in the next heat wave.
• ES Windows 5500 Series custom octagonals: The 5500 Series octagonal fixed units were shipped with a single-point glazing tape application that degrades faster in South Florida’s UV exposure than the dual-bead system ES Windows later adopted. We remove the failed tape, clean the rabbet to bare PVC, and reinstall with a structural silicone back-bead plus cap bead - the same method we use on PGT and CGI custom units, adapted to the 5500 Series frame depth.
• ES Windows 4000 Series oversized picture windows: The 4000 Series was not originally engineered for spans over 72 inches without a mullion, yet we regularly find 84-inch and 96-inch custom picture units in Kendall homes built during the 2018-2021 construction surge. The center stile deflects, the IG unit loses its edge seal, and the sash bows visibly. We specify a reinforced subframe or a factory-ordered mullioned replacement, and we document the deflection with a straightedge photo before quoting either solution.
• ES Windows custom radius tops with aftermarket glazing: Some Kendall installers substituted non-ES impact laminates in radius-top units to hit a price point, using flat glass that was heat-bent after fabrication. The result is optical distortion at the crown and premature delamination. We identify the substitute glass with a polariscope check, quote the correct ES Windows OEM curved laminate or a verified equivalent from our CWS or ECO Window Systems lines, and explain the difference in writing.
• ES Windows geometric hardware in coastal exposure: The standard multipoint lock hardware on ES Windows geometric casements uses a zinc alloy that corrodes in Kendall’s salt air within three years if the weep system is blocked. We see this on ground-floor units near Snapper Creek and the canals off SW 88th Street. Our repair includes hardware replacement with a marine-grade stainless option, weep channel cleaning and resizing, and a written maintenance note for the homeowner’s file.

Our ES Windows Custom & Geometric Windows Process

1. 1
   Measured survey: We arrive with a laser measure, a straightedge, and a camera. Sonia Raman or a verified crew member records the opening width at three heights, the radius or chord dimensions for any arch or circle, and the existing frame’s plumb and level. You keep a copy of this survey; it becomes the basis for the written quote.
2. 2
   Product specification: We determine whether your job requires an ES Windows OEM replacement, a compatible unit from our PGT, CGI, CWS, or ECO Window Systems lines, or a custom-fabricated solution. We explain the performance difference - U-factor, SHGC, impact rating, and price - in plain terms, and we note any lead time variance.
3. 3
   Written quote delivery: Haven Clause 1 requires that the measurement and the quote be the same document. You receive a line-item written scope with fixed pricing, no change orders permitted after acceptance. The quote includes the product, installation, sealant, trim, and disposal.
4. 4
   Installation and documentation: Our crew arrives uniformed and identified by license number. We dry-fit the frame before sealant application - a habit Sonia Raman established years ago that has saved multiple Kendall jobs from costly redos. We photograph each stage: the opening before, the frame set, the glazing bead installation, and the finished unit.
5. 5
   Final inspection and record: We test operation, verify lock engagement, check weep flow, and review the photo record with you. The 365-Day Done Right Promise is activated automatically; no separate registration required. You receive the final invoice, the photo documentation, and the warranty terms in one envelope.

What ES Windows Custom & Geometric Windows Costs in Kendall

These are the price ranges we have written for ES Windows custom and geometric work in Kendall over the past eighteen months. Your quote may fall outside these bounds if the opening requires structural modification or if you select a premium impact laminate.

Price movers: impact rating level (HVHZ vs. non-HVHZ), glass thickness for oversized units, interior trim complexity, and whether the existing frame can be retained or requires full removal. We do not estimate over the phone; the measured survey determines the final written price. Call (786) 321-3319 to schedule yours - estimates are free, and we offer a free second opinion on any competitor’s written quote.
