Mr-Glass Window Replacement: The West Palm Beach Owner’s Guide

If you have a Mr-Glass window with a failed sash, fogged glass, or a broken balance, we can replace it. We’re an authorized Mr-Glass installer, and we keep the most common Mr-Glass replacement parts on our trucks so most swaps in West Palm Beach happen in one visit. Installed replacement typically runs $220 to $540 per window depending on glass package and hardware, and we give you a written line-item quote before any work starts. Most owners find us when a window stops locking during hurricane season, or when condensation builds between the panes and won’t clear. That fog isn’t cosmetic; it’s the seal dead and the insulating gas long gone.

Which Mr-Glass Models This Applies To

Mr-Glass builds two broad lines in the Florida market: their single-hung and horizontal roller series, and their fixed and picture window line. The roller series is far more common in West Palm Beach homes, and it’s also the one where we see the most component failure, specifically the roller cartridges and the latch assemblies on the stile. The fixed and picture line fails differently: the glass seal breaks down, and the unit fogs or the perimeter butyl tape dries out and you get water streaks down the interior drywall after a heavy rain.

A compatibility gotcha here: Mr-Glass frames built before 2016 use a 5/8-inch sash channel, while the newer series are 3/4-inch. We’ve measured hundreds of these in West Palm Beach homes, and if you order a replacement sash or roller cartridge for the wrong channel width it won’t seat properly. We check the sticker on the top rail of the sash or the etching in the glass corner before we ever place an order. OEM parts are the first choice; they’re engineered to the exact frame extrusion and the warranty aligns with Mr-Glass’s own. There are quality aftermarket rollers and balances that work fine, but on Florida impact-rated units, we won’t substitute aftermarket glass. The impact certification lives in the OEM lamination spec, and a generic pane doesn’t carry the same blown-missile rating.

Signs Your Mr-Glass Window Replacement Is Failing

• Fog or condensation between the panes. The warm, humid air outside and the cold A/C air inside create a pressure differential. Once the edge seal on a Mr-Glass insulated unit gives out, moisture gets pulled into the airspace and you’ll never wipe it off. The glass needs replacing, not cleaning.
• The window drops or won’t stay open. On Mr-Glass roller windows, the spring balances lose tension after years of heat and salt air. When the sash slams shut on its own, that’s a balance on its way out.
• Hard cranking, grinding, or a roller that skips. The roller cartridges on Mr-Glass horizontal sliders collect sand and grit, especially in older West Palm Beach neighborhoods like Northwood Hills or El Cid where the windows have been through a decade of coastal air. A roller that skips means the bearing is flat.
• The lock or latch won’t engage. Between thermal expansion and house settling, the keepers on Mr-Glass sash locks drift. If you have to lift or force the sash to get the lock to catch, the alignment is off and the lock body is wearing.
• Drafts or water streaks along the frame edge. Older Mr-Glass installations used a foam tape corner seal that breaks down around year 8 to 10. The glass can be perfect and the frame can still leak through those corners.

Replacement Cost & What’s Included

Mr-Glass window replacements in West Palm Beach run a wider range than people expect because the glass package drives the price. A basic single-sash swap with clear glass starts around $220 installed. Replace a full impact-rated unit with Low-E and argon, and you’re looking at $380 to $540 per window. The variation comes from three things: whether it’s glass-only or glass-plus-hardware, whether the unit carries an impact rating, and whether the frame itself needs restoration. We price every job as parts plus labor, with a written quote up front, and we honor it. No change orders on our end. The swap itself is typically one visit; we bring the replacement unit to your West Palm Beach home, pull the old sash, set the new one, test the lock and the travel, and clean the track. Our work is covered by the Done Right Promise: if it’s not done right, we make it right. Period.

DIY or Call Us?

You can safely check a few things yourself: read the sticker on the top rail of the sash, note the window’s orientation, and confirm whether the frame is a 2016-or-newer 3/4-inch channel using a tape measure. That’s helpful info to have when you call. What you should not do is try to remove an impact-rated Mr-Glass sash yourself. These units are heavy, often 60 to 90 pounds in a single panel, and the failure point isn’t the fall, it’s the weight load shifting while you’re bent into the track. One wrong lift and you’ve taken out the frame rail or a finger. We’ve also seen owners order a generic replacement sash online, get the channel width wrong, and end up paying twice. If you’re in West Palm Beach and the window’s failed, call us at (561) 660-9539. If you’re still in the “what’s wrong” phase, we’ll help you identify the part over the phone and send a technician out for a free estimate.
