Boxabl Windows & Doors: The West Palm Beach Owner’s Guide

Boxabl-compatible window and door replacement in West Palm Beach typically runs $450-$1,200 per opening installed, depending on whether we’re matching a Casablanca, Boxabl Accessory Dwelling Unit, or early-production Casita Series unit. We stock the common sizes on our trucks and can usually measure, source, and install within 48 hours for standard configurations. Most Boxabl owners in West Palm Beach discover a problem when they notice the telltale gap along the weatherstrip after a summer storm, or when the sliding door starts catching on the track because the frame has shifted a quarter-inch in Florida’s humidity cycle.

Which Boxabl Models This Applies To

The window and door systems vary across Boxabl’s production runs, and matching the right part means reading the aluminum frame stamp, not guessing from outside dimensions. Casita Series units built through 2022 used a proprietary 36-inch by 60-inch horizontal slider with a single-point locking mechanism and a 2-inch frame depth; units produced after the 2023 factory retooling moved to a 2.5-inch thermally broken frame with a dual-lock system. The ADU line, including the Casablanca and the larger Ranch-style configurations, uses a different rough opening schedule entirely - 48-inch by 72-inch for the primary sliding door, with a reinforced header bracket that carries the roof load.

We source OEM Boxabl glazing where the part number is still active, but we’ve also qualified an aftermarket equivalent from a Florida manufacturer that matches the DP-50 wind pressure rating and the Miami-Dade HVHZ certification for coastal exposure. The aftermarket unit costs 15-20 percent less and carries the same ten-year glass seal warranty. For early Casita units with discontinued frame profiles, we fabricate a custom adapter trim rather than forcing a mis-sized unit into the opening, which is the shortcut that leaks every time.

To identify your unit: check the lower right corner of the sliding sash for an etched production code, or photograph the hinge side of the door frame where Boxabl stamped the lot number. Bring that photo when you call - it saves a trip.

Signs Your Boxabl Windows & Doors Is Failing

• Visible daylight between sash and frame. The bulb-style weatherstrip compresses permanently after three to four years of Florida UV exposure, and once it loses memory it won’t rebound. In West Palm Beach, we see this accelerate on east-facing walls where morning sun hits before the frame has cooled from overnight humidity.
• Sliding door requires shoulder weight to move. The tandem roller assembly collects grit from the track, or the stainless axle corrodes at the bearing race from salt air. The door feels heavy before it stops moving entirely, and forcing it bends the operating handle mechanism.
• Condensation between glass panes. The insulated glass unit has lost its argon fill and the desiccant strip is saturated. On Boxabl units, the glass is field-glazed with a snap-in bead rather than structural silicone, so the repair is a sash replacement, not a full frame tearout.
• Lock tongue won’t engage or pops back out. The zinc die-cast keeper wears where the cam strikes it, or the multipoint rod slips out of alignment when the door settles on its hinges. In 2021-2022 Casita production, the keeper was slightly undersized and wears faster than later lots.
• Frame corner gaps at the exterior trim. The Boxabl wall panel-to-window interface relies on a flexible flashing tape that degrades in our UV index. Once the seal fails, water tracks behind the trim and shows up as staining on the interior drywall below the sill.

Replacement Cost & What’s Included

For West Palm Beach Boxabl owners, window replacement runs $450-$780 per opening for standard Casita sizes, and $680-$1,200 for the larger ADU door units. The price includes removal and disposal of the failed unit, installation of the replacement with new fasteners and backer rod, exterior sealant compatible with the Boxabl wall panel finish, and interior trim touch-up. If the rough opening has water damage - common when the flashing tape has been compromised for more than one rainy season - reframing the sill adds $180-$340.

We deliver a written price before any work starts, every time. The quote itemizes the part number, labor hours, and any contingency for hidden damage, so the number you agree to is the number you pay. Under Clause 1 of the Haven Standard, no work proceeds on a change until the change order is signed. Every installation carries our 365-Day Done Right Promise, and you receive a documented photo record of the opening condition before and after, included as standard.

DIY or Call Us?

There’s a safe middle ground here. An owner can inspect the weatherstrip, clean the track with a vacuum and dry lubricant, and confirm the lock tongue moves freely - all sensible maintenance that won’t void anything. But removing a Boxabl window or door unit involves the wall panel’s structural integration: the header carries roof load, the jambs are tied to the steel frame, and the exterior flashing overlaps the weather-resistant barrier in a specific sequence. Get that wrong and you’ve compromised the building envelope, not just the opening.

We don’t recommend DIY on the insulated glass replacement either. The sash is heavy, the snap-in glazing bead requires a specific sequence to avoid cracking the replacement pane, and the argon fill is lost the moment the seal is broken. For the door roller or lock mechanism, the parts are available but the adjustment tolerances are tight - a sixteenth-inch misalignment and the multipoint won’t seat.

If you’re seeing any of the symptoms above, call (561) 475-3903. We’ll confirm the part from your photo, give you a written price, and schedule the work. Measure twice, document everything, then get out of the way and let the work speak.
