ES Windows Home Additions & ADU Nationwide

ES Windows Home Additions & ADU: The Fort Lauderdale Owner’s Guide

We stock and install ES Windows-compatible systems for home additions and ADU projects in Fort Lauderdale, with typical installed pricing from $45,000 to $130,000 for additions and $90,000 to $220,000 for detached ADUs. Most ES Windows orders for active projects can be sourced within 3-5 business days through our supplier network, and we coordinate delivery to lock in your envelope before interior trades start. Homeowners usually discover an issue when the window schedule arrives and the rough openings don’t match the ES Windows spec sheets, or when the impact-rated units specified for Fort Lauderdale’s HVHZ (High Velocity Hurricane Zone) requirements turn out to be back-ordered with no delivery date.

Which ES Windows Models This Applies To

ES Windows produces several product lines relevant to Fort Lauderdale additions and ADUs, and matching the right series to your permit drawings matters more than most owners expect. The Euro-Wave fixed and operable lines are common for modern additions with large glass walls; the ES 5000 series handles the impact ratings required in Broward County’s HVHZ without the bulk of older aluminum systems. For ADUs with tighter budgets, the ES 3000 line offers Miami-Dade NOA (Notice of Acceptance) compliance at a slimmer profile, though the maximum sash size drops from 60 inches to 48 inches, a gotcha we’ve seen derail kitchenette window layouts in Victoria Park garage conversions.

Identification starts with the etched mark on the glass spacer or the label inside the frame jamb: look for the series prefix, the NOA number, and the design pressure rating (DP-50 or higher for Fort Lauderdale). We verify this against your approved plans before ordering. OEM ES Windows units come with the full NOA documentation packet, which your building inspector will want to see; aftermarket equivalents may carry the same DP rating but lack the specific ES Windows NOA, meaning we pull a separate engineering letter and delay your rough inspection by a week. For most Fort Lauderdale additions, we spec OEM and build the cost into the written quote upfront.

Signs Your ES Windows Home Additions & ADU Is Failing

• Condensation between panes on “dry” days. The insulated glass unit (IGU) seal has failed, which in Fort Lauderdale’s salt-air environment happens faster than inland specs suggest, often 8-12 years rather than the 20-year warranty period. The desiccant inside the spacer saturates, and the Low-E coating degrades from the edge inward, visible as a hazy band.
• Frame corrosion at the weep screed (the drainage slots at the sill). ES Windows aluminum frames are anodized, but the weep channels collect salt and organic debris, accelerating pitting. We see this first on north-facing additions where moisture lingers, and it progresses to frame distortion that jams operable sashes.
• Operable sash won’t lock or seal properly. The multipoint locking hardware has worn or the frame has racked slightly out of square, common in ADUs where the slab settled after installation. The gap defeats the impact rating; in a blow, the sash can separate from the frame.
• Visible delamination of the impact interlayer. The laminated glass in HVHZ-rated units can fog at the edges as the PVB (polyvinyl butyral) layer absorbs moisture through a compromised edge seal. This starts at the corners and spreads; once visible, the unit no longer meets the NOA for projectile resistance.
• Interior drywall staining below the window head. The installation flange or pan flashing failed, or the ES Windows unit was integrated with the WRB (weather-resistive barrier) using an incompatible sealant. Fort Lauderdale’s driving rain from the southeast exposes this on the second story of additions where the original home’s eaves no longer protect the new wall.

Replacement Cost & What’s Included

For a Fort Lauderdale home addition or ADU using ES Windows, replacement of failed units runs $800-$2,500 per opening for standard sizes, with whole-envelope replacements on larger additions reaching the $45,000-$130,000 range we quote as a flat price before work starts. The spread depends on four factors: the ES Windows series (Euro-Wave custom sizes carry longer lead times and higher freight), whether the original installation included proper sill pan flashing (absent, we open the wall and rebuild), the finish trim match (stucco returns vs. interior drywall wrap), and whether the unit was part of a structural mullion assembly requiring temporary support.

Our written quote itemizes each line: ES Windows unit by series and size, freight to Fort Lauderdale, removal and disposal of the failed unit, sill pan installation or repair, integration with the existing WRB, insulation and interior trim repair, and final cleaning. Under Clause 1 of The Haven Standard, that number is fixed; no change proceeds without a signed change order, which is why our projects finish within a few percent of the agreed price. The 365-Day Done Right Promise covers the installation; ES Windows’ own glass and hardware warranties run 10-20 years depending on series, and we register those on your behalf.

DIY or Call Us?

An owner can safely verify the ES Windows label and photograph any visible symptoms for our review, but removing or installing an impact-rated unit in Fort Lauderdale’s HVHZ zone is not a homeowner project. These units weigh 40-80 pounds each for standard sizes, and the installation requires temporary bracing, proper sill pan integration with the WRB, and shimming to maintain square within 1/8 inch so the multipoint lock engages evenly. More critically, the NOA documentation must match the installed unit exactly, or the inspector fails the rough inspection and the interior trades stop.

We’ve rescued DIY starts where the owner ordered the right ES Windows model but the wrong DP rating for their specific Fort Lauderdale zone, or where the unit arrived without the NOA packet and the supplier wouldn’t release it. Measure twice, write it down, then say it once. If you’re holding a spec sheet and a concern, call (754) 254-7676 and we’ll review it line by line, no charge. Written price before any work starts, always.
