Mr-Glass Window Replacement: The Palm Beach Owner’s Guide
If your Mr-Glass window has a cracked pane, fogged glass, or a failed seal, we replace it, typically for $220 to $480 per window installed in Palm Beach, and we can usually complete the swap in one visit. Most homeowners discover the problem the same way: one morning the living room looks hazy, or a hairline crack from a hurricane-season pressure shift has spidered across the glass. You’re not just dealing with an eyesore. In this salt-air climate, a compromised Mr-Glass unit starts losing its insulating gas and lets moisture creep between the panes.

We’ve been replacing Mr-Glass windows in Palm Beach, West Palm Beach, and the surrounding stretch of the Intracoastal since 2011. Ed Winslow grew up in El Cid, a few blocks from the water, so he knows exactly what this air does to window glass over time. That’s not marketing. It’s why we stock the parts we stock.
Which Mr-Glass Models This Applies To
Mr-Glass has produced several window lines over the years, and the glass specs aren’t interchangeable across all of them. The most common units we replace in Palm Beach are single-hung and horizontal slider sashes from Mr-Glass’s 5000 and 7000 series, along with their fixed picture windows. If you still have the original window sticker or the etching in the corner of the glass, you’ll see a code that starts with “MG” followed by a series number. That code tells us the glass thickness, spacer type, and whether it’s tempered or annealed.
Here’s the compatibility gotcha most homeowners don’t know: two Mr-Glass windows that look identical from the outside may have different glass packages inside. One might be a standard insulated unit with a half-inch overall thickness. The other might be a laminated impact unit nearly three-quarters of an inch thick. Swapping one for the other doesn’t just affect the fit. It changes how the sash sits in the frame and whether the window still meets Palm Beach County’s wind-borne debris requirements. We match the replacement to the original spec, not to whatever happens to be on a shelf. If your Mr-Glass window predates the current labeling system, we measure the visible glass and the overall sash thickness to identify it.
We install OEM Mr-Glass glass where it’s still available and factory-spec equivalents when it isn’t. The difference matters less than you’d think for anything outside the warranty period, but for newer windows we’ll always check the OEM channel first. We also carry parts for PGT, CGI, and CWS windows, so if you’ve got a mixed house like many Palm Beach homes do, one call covers all of it.
Signs Your Mr-Glass Window Replacement Is Failing
- Fog between the panes that won’t wipe away. The seal between the two glass layers has failed, and humidity from outside is now trapped inside the insulated unit. In Palm Beach’s humidity, this shows up fast once the seal goes.
- Visible cracks or chips, especially after a storm. Salt air and sand make small chips spread faster here than inland. A tiny impact point near the edge of the glass becomes a full crack within weeks as temperature swings flex the pane.
- Condensation that forms on the inside surface every morning. That’s different from between-pane fog. It usually means the window’s thermal performance is shot, and the glass is conducting cold into the room where warm, humid air condenses on it.
- A milky or hazy film you can’t clean off. This is the low-E coating degrading. Once it starts, there’s no restoration; the glass is done and needs to be replaced.
- Drafts you can feel around the glass, not the frame. If you’ve ruled out worn weatherstripping and the draft persists, the glazing seal holding the glass into the sash may have failed. The unit shifts slightly in its channel, and air finds the gap.
Replacement Cost & What’s Included
In Palm Beach, expect to pay between $220 and $480 per Mr-Glass window replacement installed, depending on glass type, sash size, and whether it’s single or double pane. That’s parts and labor together, no hidden line items at the end. Here’s how it breaks down:
- Standard clear insulated unit, 30″ x 50″ or smaller: $220 to $280 installed
- Low-E insulated unit, same size range: $260 to $340 installed
- Laminated or impact-rated unit, small to mid-size: $380 to $480 installed
- Oversized or custom geometric glass: quotes on measurement, usually $350 to $700
What drives the range: glass thickness, whether it’s tempered (required by code for windows near doors or close to the floor), and how easy the sash is to remove. Older Mr-Glass sashes sometimes need new glazing beads or shims, and we roll that into the quote upfront rather than surprising you later. Every replacement carries the Done Right Promise. If it’s not done right, Ed makes it right. That’s the standard, and it’s not a limited-time anything.
You’ll also get the standing offers that apply to every job: $40 off any repair over $200, no trip charge inside our home county, and 10% off for seniors and veterans. Upfront pricing. No surprises on the invoice.
DIY or Call Us?
Replacing Mr-Glass window glass is not a weekend project for most homeowners, and we say that as people who do this every day. The glass is heavy, the sash has to come out without damaging the frame, and if the window is impact-rated, doing it wrong means the window no longer protects your home during a hurricane. That’s a safety issue, not a convenience issue.
What you can safely do before calling: note the etching code in the glass corner, measure the visible glass width and height, and take photos of both the window and the frame from a few feet back. That gives us what we need to quote accurately over the phone. What you shouldn’t do is remove the sash yourself. Improper removal is the number one cause of scratched frames and misaligned sashes we see on Palm Beach service calls. Call (561) 782-7525 and we’ll handle the rest.
FAQs
In this climate, a well-installed Mr-Glass insulated unit should last 12 to 18 years before seal failure, and the frame itself often outlasts the glass by a decade or more. Salt air and humidity are harder on windows here than the heat itself, which is why coastal-facing windows in Palm Beach tend to fail earlier than inland ones. Call (561) 782-7525 for an assessment if your windows are in that age range and showing haze.
No. Once the seal fails or the glass cracks, the unit is done. There’s no reliable way to reseal an insulated glass unit outside a factory, and any repair that claims to do it will fail again within months in Florida humidity. Replacement is the only durable fix.
Most single-window replacements are done in under two hours from arrival to cleanup. If we need to order a specific glass package, it’s typically a three to five day lead time in Palm Beach, then one visit to install.
We stock the most common Mr-Glass insulated unit sizes on our service trucks, and we carry factory-spec equivalents for discontinued glass packages. Unusual sizes, oversized units, and some impact-rated glass require a factory order, which we handle directly so you’re not chasing anything yourself.
If your Mr-Glass window is failing, call us at (561) 782-7525 for a free estimate. A live person answers, any hour. Ed’s name is on the door, and on every job we do. My name’s on the truck. That’s the only guarantee you actually need.
