Mr-Glass Window Replacement: The Boca Raton Owner’s Guide

Mr-Glass window replacement in Boca Raton typically runs $340-$780 per opening installed, depending on the series, glass package, and whether the frame is salvageable. We stock Mr-Glass-compatible sashes, balances, and glazing bead for the 5000, 6000, and 8000 series, and most replacements can be surveyed and priced same-day. Homeowners usually discover the problem when a sash won’t stay up, condensation appears between panes, or the locking mechanism grinds instead of engaging - often after a storm season or when the original install hits the 8-12 year mark in South Florida’s salt-air climate.

Which Mr-Glass Models This Applies To

Mr-Glass organizes its residential line by series number, and the part you need depends on which generation is in your wall. The 5000 series (single-hung, fixed, and horizontal roller) uses a 2-1/4 inch frame depth with a snap-in glazing bead; the 6000 series steps to 2-3/4 inches and switched to a wedge-gasket system around 2018; the 8000 impact-rated line carries a 3-inch frame and laminated glass that weighs roughly 40% more per sash. Check the spacer bar between panes or the edge of the sash for an etched code - “MG-5000-SH” or similar - or measure the visible glass width and height to the nearest 1/8 inch.

We are an independent service provider, not affiliated with Mr-Glass. For most Boca Raton jobs, we source OEM sashes and hardware directly through Mr-Glass’s Florida distributor network. Aftermarket equivalents exist for balances and rollers, but we do not substitute on impact-rated glass packages - the NOA (Notice of Acceptance) traceability matters for your wind mitigation form, and only OEM laminated glass carries the original certification. One compatibility gotcha: the 6000 series pre-2018 used a 5/8 inch balance shoe that Mr-Glass phased out; the current replacement is 3/4 inch, which means the jamb liner needs swapping too. We verify this on site before ordering.

Signs Your Mr-Glass Window Replacement Is Failing

• The sash drops or won’t stay open. The coil balance has lost tension or the shoe is cracked. In Boca Raton’s humidity, the nylon balance shoes degrade faster than the manufacturer rates them - we see this at 7-9 years instead of the printed 15.
• Fog or moisture between the glass panes. The insulated glass unit (IGU) seal has failed. Once argon escapes and desiccant saturates, the glass is done; there is no reliable reseal for residential IGUs in this climate.
• The lock lever turns but doesn’t engage the keeper. The multipoint lock mechanism has worn or the frame has settled, throwing off alignment. We check plumb first - if the frame is racked, a new lock won’t solve it.
• Visible corrosion on the frame corners or weep holes. Salt air accelerates galvanic corrosion where aluminum meets dissimilar metals. Mr-Glass frames are anodized, but the weep-hole baffles are pot metal and fail first.
• Cracked or delaminating impact glass. Impact-rated laminated glass can spider without shattering, but the interlayer degrades with UV exposure. If you can push a fingernail into a crack and feel layers separating, the impact rating is compromised.

Replacement Cost & What’s Included

What drives the range: glass package (single-pane, insulated, or impact-laminated), whether the existing frame is square and dry, and access - second-story openings in Boca Raton’s gated communities like Broken Sound or Royal Palm Yacht Club sometimes require scaffolding instead of ladders. Our price includes the measured survey you keep, the written scope, installation, and the documented photo record. Every Mr-Glass replacement carries our 365-Day Done Right Promise under the Haven Standard - if the sash doesn’t operate smoothly or the lock doesn’t set flush, we return and correct it. No change orders, no surprise fees. Measure it twice, write it down, then we can talk price.

DIY or Call Us?

There is a safe middle ground. You can verify the model number, check the weep holes for blockage, and photograph any etched codes on the glass spacer - that information saves us twenty minutes on site. What we do not recommend: removing a sash with a failed balance (the counterweight is under tension and can snap the jamb liner), cutting glazing bead with a utility knife near tempered glass (spontaneous fracture risk), or handling laminated impact glass without edge protection (the layers separate if nicked). Mr-Glass sashes are heavier than they look; the 8000 series single-hung sash runs 35-45 pounds. If the frame is out of square by more than 1/4 inch, a DIY sash swap will bind within a season. Call (561) 200-8592 and we’ll survey it, write the price, and schedule the work when you’re ready.
