Mr-Glass Home Additions & ADU: The West Palm Beach Owner’s Guide
Mr-Glass home additions and ADU projects in West Palm Beach typically run $45,000 to $130,000 installed, with standalone ADU construction ranging from $90,000 to $220,000. We stock Mr-Glass-compatible framing hardware, glazing channels, and corner posts, and we install against the written scope, not a guess. Most owners call us because a joint has pulled loose, a panel has fogged, or the addition wasn’t flashed right the first time and South Florida humidity is now doing what South Florida humidity does.
The failure picture is usually the same: you walk the perimeter after a heavy rain and see water staining at the sill, or you put your hand on the frame and feel movement that shouldn’t be there. Mr-Glass systems rely on tight dimensional tolerances. When the substrate shifts, the glass doesn’t absorb the movement, the frame does, and something gives. We identify which part gave, match it to the correct Mr-Glass series, and replace it without rebuilding the whole wall.
Which Mr-Glass Models This Applies To
Mr-Glass built its home addition and ADU line around a few core glass wall systems, and the parts are not interchangeable across all of them. The main compatibility split is between the standard residential series, which uses 3/8-inch tempered glass in aluminum channels, and the heavier structural series, which steps up to 1/2-inch laminated glass and deeper corner posts. You cannot take a glazing bead from one and fit it to the other. The extrusion profiles differ by roughly 3 millimeters, which is enough to fail.
To identify what you have, look at the vertical track on the inside of the frame. Mr-Glass stamps a series code near the bottom, typically two letters followed by four digits. If the label is gone or painted over, measure the glass thickness with a caliper at the edge, and measure the channel mouth opening. That tells us which parts catalog to pull from. We also work with documented aftermarket equivalents for Mr-Glass where they match or exceed the OEM spec, but we’re direct about when they don’t. For a load-bearing corner post, we use the OEM part. For a rubber glazing wedge that just holds glass vibration-steady, a quality aftermarket match is fine and can save money. Bradford Remodeling Co West Palm Beach is an independent service provider, not affiliated with Mr-Glass, so we have no financial reason to push OEM when the math says otherwise.

Signs Your Mr-Glass Home Additions & ADU Is Failing
- Water staining or soft drywall at the sill line. This usually means the sill flashing or the weep system has failed. In West Palm Beach, the rain comes sideways in summer storms, and a sill that sheds water slowly is a sill that’s already behind. Water sits, drywall wicks it, and the stain shows up months later.
- Visible gap between glass edge and frame. The glazing wedge has compressed or degraded. Tempered glass shouldn’t rattle in a properly seated channel. If you can slip a piece of paper between glass and rubber, the wedge needs replacement before the glass starts working against the metal track.
- Door or panel drags when opening. Framing on home additions settles, particularly in Florida where slab movement is common after a dry season followed by heavy rain. A dragging panel means the header or the corner post has shifted out of square. The fix is re-shimming and re-anchoring, not forcing the door.
- Condensation or fog between double-glazed panels. The desiccant in the spacer failed or the edge seal broke. You cannot clean the inside of a sealed unit. The panel gets replaced, and we order it to the exact rough opening dimensions from the original install, not an approximate size.
- Screw or anchor heads pulling through the aluminum track. This is the structural one. The track was either anchored to a substrate that wasn’t squared or the anchor spacing was stretched. The track pulls, the glass binds, and the entire run needs to be re-set.

AfterReplacement Cost & What’s Included
For most Mr-Glass home addition and ADU repairs in West Palm Beach, you’re looking at $45,000 to $130,000 when the work involves re-framing, re-glazing, or replacing structural members on an existing addition. Smaller scoped repairs, like a single fogged panel swap or a glazing wedge replacement on one wall, land lower, often in the $2,000 to $8,000 range depending on panel size and whether we’re pulling permits. The range moves on three things: glass thickness (3/8 versus 1/2-inch laminated), the number of linear feet of track that needs re-anchoring, and whether we’re working around existing finishes or tearing them out and rebuilding.
Every line item is priced before we start. Parts and labor are separated on the written quote, so you see exactly what the glass costs and exactly what the crew costs. The 365-Day Done Right Promise covers all of it. If the replacement fails inside the first year, we return and correct it at no charge. No reimbursement forms. No argument about whether it was “installation error.” If it’s not done right, we make it right. That’s the whole guarantee, in writing.
DIY or Call Us?
There are things you can safely check before calling. Look for the series code stamp. Take photos of the failed area with a tape measure in the frame for scale. Check whether your insurance paperwork from the original build lists the glass spec. Those three things save time on the first visit. What you shouldn’t do is try to re-seat tempered glass yourself. Tempered glass under edge stress doesn’t crack gradually, it shatters, and the pieces come down fast and hard. Likewise, corner posts on Mr-Glass additions carry structural load. If a post is compromised, the glass wall is carrying weight it wasn’t designed to carry. That’s not a weekend job.
If the issue is a loose screw or a sagging hinge on a door panel, that’s often a simple field adjustment. We’ll tell you over the phone if it’s something you can handle. If we say it’s a two-man job with suction cups and a torque wrench, that’s what it is, and the price we quote is the price on the invoice. Call (728) 203-9809 and we’ll walk through what you’re seeing.
FAQs
In West Palm Beach, expect 15 to 25 years from the glass and aluminum frame before the glazing wedges, seals, and weep systems need attention. The glass itself will outlast the hardware. What kills these systems early is salt air near the coast and repeated thermal cycling from summer heat followed by evening thunderstorms. Commercial properties on Flagler Drive tend to show rubber degradation faster than homes further inland, where the salt concentration drops off.
No. A fogged double-glazed panel cannot be resealed in the field, and a cracked tempered panel cannot be glued. The correct fix is measuring the rough opening, ordering a matching replacement panel to the original spec, and re-setting it with new glazing wedges. Attempting a field reseal fails within a season in South Florida humidity.
Most single-panel swaps and hardware replacements are finished in one day. A full re-glaze or re-anchoring of a long wall run takes two to three days, including cleanup. We keep common Mr-Glass glazing wedges, corner keys, and anchor clips stocked in our West Palm Beach trucks. Odd-size panels and structural posts are ordered to spec, and lead time is usually 5 to 10 business days.
We stock the common wear items, glazing wedges, corner keys, sill flashings, and anchor clips, on our trucks. For series-specific extrusions, structural posts, and custom-dimension glass panels, we order direct to the measurements from your existing install. That keeps the lead time predictable and the fit exact. Call (728) 203-9809 for an exact quote, estimates are free.
