How ES Windows Products Fail - and How We Fix Them

• ES-7000 Series: seal failure in the insulated glass unit (IGU). The ES-7000 uses a dual-seal warm-edge spacer system that holds up well in dry climates but can degrade faster in Boca Raton’s salt-air environment, particularly within three miles of the Intracoastal. We see the telltale fogging at the bottom third of the sash first. Our fix: measure the sightline and glazing pocket, order a replacement IGU with upgraded dual-seal construction, and document the U-factor and SHGC before and after installation.
• ES-500 Series: Low-E coating degradation on west-facing elevations. The sputtered soft-coat Low-E on early ES-500 production runs can oxidize when exposed to prolonged afternoon UV combined with reflective heat from pool decks or hardscaping, common in Boca Raton’s Royal Palm Yacht & Country Club area. The glass looks hazy but isn’t cracked. We replace the lite with current-spec ES-500 glass or cross-reference to a PGT or CGI equivalent if lead times stretch.
• ES-9000 Impact: argon gas escape through micro-fractures in the laminated layer. The ES-9000’s impact-rated laminated glass can develop hairline stress cracks at the edge after repeated pressure cycling during hurricane season. Argon leaks out; the center-of-glass U-factor rises from 0.30 to 0.38 or higher. We pressure-test the IGU, identify the leak path, and replace with OEM or spec-matched laminated glass from our CWS or ECO Window Systems inventory if ES factory stock runs thin.
• ES-3000 vinyl line: frame expansion causing sash misalignment. The ES-3000’s multi-chamber vinyl profile expands roughly 1/8 inch per 6 feet in Boca Raton’s summer heat, which can bow the frame and break the compression seal against the weatherstrip. The homeowner feels a draft but sees no broken glass. We relevel the frame, replace the bulb seal with silicone-weatherized extrusion, and verify with a smoke pencil at the lock rail.
• ES Windows sliding patio door: roller wear from sand infiltration. The stainless steel rollers in ES sliding systems grind against silica tracked in from Boca Raton’s beach-adjacent properties, particularly in neighborhoods east of A1A. The door gets heavy; the sash drops and compromises the interlock seal. We replace the roller carriage, vacuum the track, and check that the meeting stile maintains uniform contact pressure top to bottom.

Our ES Windows Energy-Efficient Windows Process

1. 1
   Measured survey. Sonia Raman or a verified crew member arrives with a written scope template, records every opening’s rough width, rough height, wall thickness, and existing frame condition. You keep a copy before we leave.
2. 2
   Diagnostics and documentation. We test for seal failure with a deflectometer where fogging is present, check frame square with a laser level, and photograph every condition. The photo record becomes part of your job file.
3. 3
   Parts decision with full disclosure. If ES factory stock is available within your timeline, we quote OEM. If lead times exceed two weeks or the series is discontinued, we present a cross-referenced equivalent from PGT, CGI, CWS, or ECO Window Systems with matching U-factor and SHGC ratings. You choose; we document the spec sheet.
4. 4
   Installation under Haven Standard protocols. Verified crew, license number confirmed before arrival, uniformed, background-checked. We install to the measured survey, not to “close enough.”
5. 5
   Post-install testing and handoff. Operate every sash, check weatherstrip compression, verify lock engagement, and run a final photo record. The written invoice matches the written quote to the dollar.
6. 6
   365-Day Done Right Promise activation. Your job enters our log with brand, glass package, U-factor, date, and your name. If something drifts out of spec within a year, we make it right.
