Cover Home Additions & ADU Nationwide

Cover Home Additions & ADU: The West Palm Beach Owner’s Guide

We stock and install Cover-compatible components for home additions and ADU projects in West Palm Beach, with typical installed pricing from $45,000 to $130,000 for additions and $90,000 to $220,000 for full ADU construction. Most Cover-related framing, window, and door integration work is completed within the quoted timeline, and we carry common Cover window and door specifications on our trucks for same-day resolution when a match is needed. Homeowners usually discover an issue when a Cover window won’t seat properly in a new addition frame, a sliding door track binds after rough-in, or an inspector flags a mismatch between the Cover unit’s Florida Product Approval and the addition’s wind-load documentation.

Which Cover Models This Applies To

Cover manufactures impact-rated windows and sliding glass doors under several series lines common in South Florida construction. The most frequent matches we see in West Palm Beach are the Cover Impact Plus single-hung and horizontal roller series, plus the Cover Slide-Tek patio door line. To identify your exact unit, check the etched mark in the glass corner for the series code (IP-SH, IP-HR, or ST-PD followed by a four-digit size code) and the Florida Product Approval number, which must match your addition’s permit documentation.

The OEM-versus-aftermarket question for Cover units is straightforward in our experience. Cover’s own replacement sashes and frame kits are available through regional distributors in Miami-Dade and Broward counties, with typical lead times of five to ten business days. We also source compatible aftermarket frames from CWS and PGT that meet the same Miami-Dade HVHZ standards and often carry comparable or longer warranty terms. The critical compatibility gotcha: Cover’s older pre-2018 Slide-Tek doors used a 2.75-inch frame depth, while post-2018 production shifted to 3.25 inches. Matching the wrong frame to your rough opening means reframing, not just swapping hardware. We measure twice before ordering anything. “Measure twice, document everything, then get out of the way and let the work speak.”

Signs Your Cover Home Additions & ADU Is Failing

• Window sash won’t lock or seal. The interlock rail on Cover impact windows can fatigue after repeated cycling, especially in West Palm Beach’s salt-air environment where aluminum components oxidize faster than inland specs. We find the interlock misalignment starts small, then the sash rack strips trying to compensate.
• Sliding door binds or jumps the track. Cover Slide-Tek doors rely on tandem roller assemblies that clog with construction debris during addition rough-in. If the door wasn’t protected during framing, drywall dust and grit embed in the bearing races and the stainless track develops flat spots.
• Visible gap between frame and wall after settling. New additions in West Palm Beach’s sandy substrate often settle 3 to 6 millimeters in the first eighteen months. Cover’s installation clips are designed for adjustment, but if the original crew shimmed tight instead of leaving travel, the frame twists and the glass stresses.
• Condensation between panes on impact glass. Cover’s laminated impact glass uses a polyvinyl butyral interlayer that can delaminate at the edge if the unit sits in direct afternoon sun without proper overhang. Once the edge seal breathes, desiccant saturation follows and the fog is permanent.
• Inspector flags Product Approval mismatch. This is the paperwork failure mode: the Cover unit on site carries a Florida Product Approval for 140 mph design pressure, but the West Palm Beach addition permit requires 150 mph per the 2023 Florida Building Code update. The unit isn’t broken; it’s just wrong for the jurisdiction, and replacement is the only fix.

Replacement Cost & What’s Included

What drives the range: unit size, whether the original frame can be preserved, and whether the addition’s rough opening was framed to standard or custom dimensions. Under Clause 1 of the Haven Standard, the price we write is the price before any work starts. That quote includes parts, labor, permit coordination, and our 365-Day Done Right Promise. No change proceeds without a signed change order, which is why our projects finish within a few percent of the agreed number.

DIY or Call Us?

An owner can safely check the etched glass mark and photograph the Florida Product Approval label for reference. You can also verify whether the window or door operates smoothly when the addition is at neutral temperature, expansion and contraction often reveal binding that temperature masks.

Where DIY goes wrong: impact-rated window and door units in West Palm Beach are heavy, typically 40 to 80 pounds per sash, and the laminated glass can shatter outward if mishandled. More critically, removing a Cover unit from a framed opening compromises the water management system, the sill pan, flashing tape, and head detail must be reinstalled to code or the addition leaks into the wall cavity. We have seen homeowners attempt a sash swap, then discover the frame is out of square by half an inch and the new unit won’t seat. At that point, the call costs more than if we’d handled it from the start. For a written price before anyone touches a tool, call (561) 475-3903.
