ES Windows Energy-Efficient Windows in Fort Lauderdale: What to Know First

We provide independent ES Windows energy-efficient windows in Fort Lauderdale, typically completing measured surveys within 48 hours of first contact and installations on a scheduled date that both parties confirm in writing. Our written quote is the final invoice - Haven Clause 1 means the price named before any work starts is the price paid after cleanup. This page is for ES Windows owners in Fort Lauderdale whose units are underperforming on energy ratings, showing seal failure, or who need Low-E or argon-glass upgrades on existing frames. Call (754) 666-7478 to schedule your free measured survey.

How ES Windows Products Fail - and How We Fix Them

• ES Windows 400 Series fixed picture windows: The dual-pane seal fails prematurely in Fort Lauderdale’s salt-air corridor, particularly within three miles of the Intracoastal. Argon escapes, condensation forms between lites, and the center-of-glass U-factor degrades from the rated 0.30 to something closer to 0.45. We measure the actual sightline and either replace the insulated glass unit with OEM-spec laminated Low-E or, if the frame extrusion is still square, retrofit with a quality aftermarket IGU that carries the same Miami-Dade Notice of Acceptance number.
• ES Windows 500 Series single-hung operables: The balance shoe track accumulates corrosion from coastal humidity, causing the sash to drop or tilt. Homeowners crank the lock harder, distorting the meeting rail and breaking the thermal break continuity. We pull the sash, document the rail deflection with photos the customer keeps, and replace the balance assembly with OEM-spec components rather than universal retrofits that don’t match the original spring rating.
• ES Windows 8000 Series horizontal rollers: The wool pile weatherstrip compresses permanently after four to six years of UV exposure in Fort Lauderdale, creating an air infiltration path that the homeowner feels as “a draft” but shows on our blower-door test as a measurable leakage site. We source the exact pile height and backing width from the original extrusion drawings, not generic slide-in replacement, because the wrong pile depth damages the roller track.
• ES Windows laminated impact units with Low-E coating: The metallic oxide layer degrades from the outside in when the exterior lite suffers micro-pitting from wind-borne sand along A1A and the beach neighborhoods. Visible symptom: a hazy iridescence at oblique angles, not cracks. We identify this during our measured survey with a flashlight held at 15 degrees to the glass plane, then specify replacement with upgraded solar-control Low-E if the frame is salvageable.
• ES Windows thermally broken aluminum frames: The polyamide strut swells from repeated wet-dry cycling in Fort Lauderdale’s summer humidity, creating a gap between strut and extrusion that breaches the thermal barrier. The interior frame surface runs cold in January, condensing moisture and breeding mold on the drywall return. We document the gap with feeler gauges, photograph the reading, and replace the entire frame assembly rather than attempting a partial repair that leaves the thermal bridge intact.

Our ES Windows Energy-Efficient Windows Process

1. 1
   Measured survey. We arrive with a laser measure, level, and thermal camera. Sonia Raman or a Haven-certified technician records every rough opening dimension, notes the existing ES Windows series from the etched mark in the glass corner, and checks the frame for square and plumb. The customer keeps this document.
2. 2
   Diagnosis with evidence. We run a blower-door-informed smoke pencil test on operable units, photograph any seal degradation or thermal-break gaps, and identify whether the failure is glass, frame, or hardware. No guesswork enters the written scope.
3. 3
   Parts specification. OEM ES Windows components when available and cost-justified; quality aftermarket when the OEM lead time exceeds three weeks or the part is discontinued. We name the manufacturer and the Miami-Dade NOA number on the quote, never “comparable” or “equivalent.”
4. 4
   Installation with documentation. Background-checked, uniformed technicians with license numbers confirmed before arrival. Every step photographed: old unit out, rough opening condition, new unit set, shimming, fastening pattern, sealant bead. The customer receives the photo record within 24 hours.
5. 5
   Performance verification. We retest operable units for air infiltration, verify the lock throw engages fully, and confirm the sash travels smoothly through its full range. Thermal camera spot-check on Low-E units to confirm coating uniformity.
6. 6
   Written closeout. The invoice matches the quote to the dollar. The 365-Day Done Right Promise is stamped and dated. The documented photo record is delivered. No surprises - Haven Clause 5.
