Mr-Glass Home Additions & ADU: The West Palm Beach Owner’s Guide
A Mr-Glass home addition or ADU in West Palm Beach typically costs between $45,000 and $130,000 for the full build, with ADU construction running $90,000 to $220,000 depending on square footage and site conditions. We stock and install the structural components, window and door packages, and finish materials that keep a Mr-Glass addition weathertight through Florida’s hurricane season, and we can usually have a failing component assessed within one to two business days. Most owners discover something’s wrong the way you’d expect in South Florida: a hairline crack along a corner bead after a summer of humidity swings, a window that suddenly won’t latch square, or a door that drags against its frame after the slab settles a quarter inch. What starts as a cosmetic annoyance usually points back to moisture, movement, or a connection detail that was never flashed properly in the first place.
If a component of your Mr-Glass addition is failing, the fastest way to a real answer is a written diagnosis. Call (728) 203-3270 and we’ll put eyes on it, name the part, and hand you a line-item price before any work begins.
Which Mr-Glass Models This Applies To
Mr-Glass additions and ADUs built in the West Palm Beach area generally fall into two construction categories: stick-framed additions tied to the original roofline, and pre-engineered ADU shells assembled from panelized wall systems. The parts that fail differ by category, and matching the right replacement depends on which one you have.
The stick-framed additions use standard dimensional lumber and off-the-shelf fasteners, which makes replacement straightforward, but the interior finish materials, corner beads, drywall reveals, and window flashing details, were often specified to match the original structure’s profiles. A corner bead from a big-box store won’t sit flush against Mr-Glass’s tighter drywall reveals, which run about 1/8 inch narrower than standard residential work. The panelized ADU shells are a different animal entirely: the wall panels use a proprietary tongue-and-groove connection with 3/8-inch cam-lock fasteners, and the exterior cladding overlaps in a specific sequence. You can’t swap one panel for a generic sheet of sheathing without breaking the water barrier’s continuity. For OEM parts, Mr-Glass sources window and door packages from regional Florida suppliers who stamp their components for coastal wind loads. Quality aftermarket equivalents exist, and we’ll recommend them when the OEM part is overpriced or backordered, but we’ll always tell you which one we’re quoting and why. The written price lists the brand and part number either way.
Compatibility gotcha to know: Mr-Glass ADU panels manufactured before 2019 used a 2-1/2 inch cam-lock receiver. The current production run uses a 2-3/4 inch receiver. They look identical in a photo, but the old part will not seat in a new panel’s track. Someone has to measure before ordering. Someone will.
Styles & brands we work with
Signs Your Mr-Glass Home Additions & ADU Is Failing
- Hairline cracks radiating from window corners at a 45-degree angle. This usually means the header above the window is undersized or the rough opening flashing wasn’t lapped correctly. Water gets in, the framing swells, and the drywall telegraphs the movement. In Flamingo Park, we see this on south-facing walls more than anywhere else, the afternoon sun bakes the stucco, and the thermal cycle works every seam loose.
- A door that latches fine in January but drags in August. That’s slab movement, not a bad hinge. The soil under a West Palm Beach addition expands and contracts with the water table, and a slab that was poured without proper compaction will lift seasonally. The door drag is the symptom; the soil is the cause.
- Window condensation between the glass panes. The insulated glass unit’s seal has failed. In Florida’s humidity, a failed seal means the argon or krypton fill is gone and the window’s thermal performance drops by roughly 30%. You can’t reseal an IGU; the glass pack gets replaced.
- Baseboard pulling away from the wall at the floor line, with a faint musty smell behind it. Water is wicking up from the slab edge. Mr-Glass additions that used a standard sill plate without a capillary break are prone to this. The fix involves pulling the baseboard, treating the sill, and replacing the damaged drywall, not just nailing the trim back on and painting over it.
- A soft spot in the floor near the bathroom or laundry wall. A slow supply-line leak, a failed wax ring, or condensation from a poorly vented fixture has been rotting the subfloor. By the time the tile feels spongy underfoot, the damage underneath is always bigger than the visible area suggests.
Replacement Cost & What’s Included
For Mr-Glass home additions and ADUs in West Palm Beach, the full replacement of a failed structural or envelope component runs from $45,000 to $130,000 for a stick-framed addition, and $90,000 to $220,000 for a complete ADU build when the existing shell can’t be salvaged. Smaller, targeted repairs, a single window pack, a door replacement with re-flashing, a section of rotted subfloor, fall well below that and get priced individually. The range on any given project is driven by access, how much of the existing framing is still sound, permit requirements, and whether the failed part was original or already someone’s patch.

There are things you can check without picking up a tool. Look at the caulk lines around windows and doors: if the caulk is pulling away from the stucco or the glass, that’s a flashing or seal issue you should photograph and send to us. Check for daylight under exterior doors. Run your hand along the baseboards after a heavy rain and feel for dampness. Those observations help us diagnose faster, and you’re welcome to do them.
What you should not do is cut into a wall, pull a window, or open the exterior cladding to “see what’s going on.” Mr-Glass ADU panels carry tension in the cam-lock connections, and releasing the wrong fastener can shift a wall section. Improperly re-flashing a window against Florida’s driving rain means the water you let in today becomes the mold you’re fighting next year. The safe call is a phone call. Reach us at (728) 203-3270 and we’ll schedule a diagnostic visit, name the part, and put the fix in writing.
Key Takeaways
- Mr-Glass additions and ADUs in West Palm Beach fall into two build types: stick-framed and panelized. Parts are not interchangeable between them.
- The full replacement range is $45,000 – $130,000 for additions and $90,000 – $220,000 for ADUs; targeted component repairs cost far less and are quoted individually.
- Window corner cracks, seasonal door drag, and between-glass condensation are the three most common failure signs we see in this climate.
- A written price comes before any work starts, every time. The price in writing is the price you pay.
- Our 365-Day Done Right Promise covers every completed project. If it’s not done right, we make it right.
FAQs
A properly flashed window or door package in a Mr-Glass addition should last 20 to 30 years in West Palm Beach’s climate, but that assumes the original flashing was lapped correctly and the sealants were UV-rated. Panels and structural framing should last the life of the structure. The components that fail early are almost always the ones where a shortcut was taken at the connection point: no capillary break, wrong caulk, missing kickout flashing.
Sometimes. A window with blown glass can be re-glazed with a new IGU without replacing the frame, and a section of rotted sill plate can be sistered and treated if the damage hasn’t spread past a localized area. But if the failure is structural, a cracked header, a compromised panel connection, the safe answer is replacement, not patching. We’ll tell you which one you’re looking at and why, in writing, before you commit to anything. Call (728) 203-3270 for an exact diagnosis.
A single window or door replacement, including proper re-flashing and interior trim work, takes one to two days on site. A section of failed ADU wall panel with stucco and interior drywall repair runs three to five days, depending on curing time for the finish coats. A full addition or ADU rebuild is scheduled in weeks, not days, and we’ll give you a firm start and end window in the written scope of work.
We stock the common failure points on our service vehicles: standard cam-lock fasteners in both the 2-1/2 and 2-3/4 inch sizes, PVC trim coil in the Mr-Glass reveal profiles, flashing tapes rated for Florida’s UV exposure, and sealants matched to the original substrates. Specialty components, a specific IGU, a custom exterior door, get ordered after we confirm the measurements on site. Most parts arrive in West Palm Beach within three to five business days.
