ES Windows Home Additions & ADU Nationwide

ES Windows Home Additions & ADU: The Pompano Beach Owner’s Guide

ES Windows impact-rated windows and doors installed in Pompano Beach home additions and ADUs typically run $8,000-$25,000 for a full replacement package, with individual frame assemblies, impact glass units, and hardware kits stocked locally for same-day installation when the opening dimensions match standard ES catalog sizes. Most Pompano Beach owners discover their ES Windows unit is failing when they notice salt-air corrosion on the coastal-grade anodized frame, fogging between the laminated glass plies, or the multi-point locking system binding after a storm season. We’ve replaced ES Windows components in additions across Pompano Beach’s beachside neighborhoods and inland subdivisions alike, and the pattern is consistent: Florida’s salt-laden coastal air attacks the weep screed and frame corners first, while the laminated impact glass outlasts the seals if the installation was done with proper slope and drainage.

Which ES Windows Models This Applies To

ES Windows manufactures several series relevant to Pompano Beach home additions and ADU construction, and matching the right replacement part starts with the etched mark in the glass corner or the label on the frame jamb. The ES 5000 Series and ES 8000 Series are the two we encounter most often in local additions; the 5000 uses a 2.5-inch frame depth with a single-fin installation flange, while the 8000 steps to 3.25 inches with a dual-fin flange and heavier wall extrusion for larger openings. The ES C5400 architectural line appears in higher-end Pompano Beach ADUs where the owner specified a thinner sightline, but the hardware and glass retention system differ materially from the 5000/8000 platforms.

To identify your unit, check the permanent etch in the lower corner of the glass: it reads “ESW” followed by a four-digit series code and the Miami-Dade HVHZ approval number, typically NOA-20-XXXX.XX. The frame label, visible when you open the sash, lists the exact nominal size, series, and finish code. We carry replacement sashes, frame corners, and complete jamb assemblies for the 5000 and 8000 series in white and bronze anodized; the C5400 line requires a factory order with a 10-14 day lead time. Aftermarket equivalents exist for the 5000/8000 hardware and weatherstrip, but we source OEM ES Windows glass units and frame extrusions because the laminated interlayer thickness and frame tolerances are proprietary. A mismatched sash in an ES frame will leak air and void the HVHZ rating, which is not a risk worth taking in Broward County’s wind-borne debris zone.

Signs Your ES Windows Home Additions & ADU Is Failing

• Fogging or haze between glass plies. The laminated impact glass in ES Windows units uses a polyvinyl butyral (PVB) interlayer sealed to the frame with a dual-durometer gasket. When the primary seal degrades from UV exposure and thermal cycling, moisture migrates into the airspace. In Pompano Beach, we see this accelerate on east-facing additions where morning sun hits salt residue; the glass is intact but the thermal and optical performance is gone.
• Frame corner separation or weep screed blockage. The aluminum frame corners in ES 5000 and 8000 series are mechanically joined and sealed. Salt accumulation in the weep channels causes galvanic corrosion at the corner keys, and blocked drainage forces water into the wall cavity instead of out. We find this routinely in Pompano Beach additions within a half-mile of the Intracoastal, where the salt air is constant.
• Multi-point lock misalignment or handle resistance. The ES locking system depends on precise keeper-to-bolt engagement across three or five points. Frame settlement in a home addition, common in the first 24-36 months after construction, shifts the geometry; the handle grows stiff, then the cam mechanism strips. Forcing it bends the internal rods, and the repair escalates from adjustment to full hardware replacement.
• Air infiltration at the sash perimeter. The compression weatherstrip in ES units is a dual-bulb silicone design with a 15-year rated life. Florida heat hardens it prematurely, and once the bulb loses resilience, you feel the draft and hear wind noise. The strip is replaceable without removing the sash, but owners often miss the early signs until the energy bill jumps.
• Impact glass spider-cracking without breach. ES laminated glass can fracture internally from thermal stress or minor impact while the outer ply holds. The unit is still structurally sound but no longer meets the HVHZ standard for wind-borne debris resistance. We flag this immediately; a cracked impact window in a Pompano Beach addition is a code compliance issue at resale and a safety liability during a named storm.

Replacement Cost & What’s Included

For a Pompano Beach home addition or ADU using ES Windows, full-frame replacement of a typical 6-foot sliding unit runs $1,800-$3,400 installed; sash-only replacement in a sound frame drops to $900-$1,600; and component repairs like hardware or weatherstrip range from $180-$450. A complete ES Windows package for a 400-square-foot ADU addition, including three openings and a sliding door, lands in the $12,000-$22,000 range depending on series selection and finish.

What drives the range: series selection (8000 over 5000 adds 20-25%), custom sizes outside the catalog, finish upgrades from white to bronze or custom anodize, and the condition of the surrounding substrate. If the addition’s framing has moisture damage from a leaking unit, we document it with photos, quote the repair separately, and nothing proceeds without a signed change order. Under Clause 1 of The Haven Standard, the price is written before anyone starts. Our 365-Day Done Right Promise covers the installation; the ES Windows manufacturer’s glass warranty runs 10 years on the laminated unit.

DIY or Call Us?

An owner can safely inspect their ES Windows unit for the symptoms above: open the sash, check the etched glass mark, photograph any frame damage, and test the lock points with the handle. What we do not recommend is removing a fixed sash or attempting to reglaze a laminated impact unit. The glass weighs 8-12 pounds per square foot, the retention system uses tamper-resistant fasteners, and a dropped laminated pane can still lacerate; more critically, improper reinstallation voids the HVHZ rating and the manufacturer’s warranty. We carry ES 5000 and 8000 series sashes, frame corners, and hardware kits on our Pompano Beach trucks, and we stock the specialized setting blocks and shims that ES specifies for their frame system. Measure twice, say it once, show your work - that applies to window installation too. Call (754) 714-6540 and we’ll confirm the part match before we roll.

FAQs

How long do ES Windows last in Pompano Beach’s coastal climate?

With proper installation and maintenance, the laminated glass and aluminum frame will exceed 25 years, but the weatherstrip and sealant need attention at year 10-12 and the hardware at 15. We see premature failure when the weep system was not cleaned or when the original installer used non-compatible sealant. Call (754) 714-6540 for an inspection - estimates are free.

Can a fogged ES Windows unit be repaired instead of replaced?

No. Once moisture breaches the primary seal in a laminated impact unit, the glass pack is permanently compromised. Defogging services do not restore the structural or thermal performance, and they void the HVHZ approval. Replacement with an OEM sash is the only compliant repair. Call (754) 714-6540 for exact sizing.

How long does an ES Windows replacement take?

A sash swap in an existing frame takes 45-90 minutes per opening; a full-frame replacement with trim work runs 3-5 hours. An ADU package we sequence across two days to avoid leaving openings unsecured overnight. We pull permits for all Pompano Beach work and schedule inspection before we close. Call (754) 714-6540 to schedule.

Do you stock ES Windows parts?

We stock ES 5000 and 8000 series sashes in common Pompano Beach sizes - 2/0 x 3/0, 2/4 x 4/0, 3/0 x 5/0, 6/0 sliding - plus hardware kits, weatherstrip, and frame corners. Custom sizes and C5400 series require a 10-14 day factory order. We’ll verify stock against your etched glass mark when you call. Call (754) 714-6540 with your NOA number ready.
