Mr-Glass Window Replacement Nationwide

Mr-Glass Window Replacement: The Jacksonville Owner’s Guide

If you have a Mr-Glass window with a failed sash, fogged glass, or a balance that won’t hold, we stock and install Mr-Glass-compatible replacement parts across Jacksonville, with most single-window replacements running $240 – $480 installed depending on the series and glass package. We keep common Mr-Glass balance assemblies, tilt latches, and insulated glass units on our trucks, so a single-window repair is usually finished in under two hours once we’re on site. The typical call starts with a window that won’t stay up, a pane that’s fogged between the glass, or a lock that no longer catches. If that sounds familiar, this page walks you through the part, the price, and what to check before you pick up the phone.

Which Mr-Glass Models This Applies To

Mr-Glass builds single-hung, double-hung, and horizontal slider windows, most commonly in vinyl frames with two glass thicknesses: 3mm single-strength or 7/8-inch insulated units. The crucial detail is the balance system. Mr-Glass uses a block-and-tackle balance on most double-hungs built after 2010, but some earlier Jacksonville installs have spiral balances instead. The two are not interchangeable, and a mismatched balance will either slam the sash or fail to hold it. Look for a stamp on the top of the sash or a sticker on the frame’s side channel. If it reads “BT” followed by a number, you have block-and-tackle. If you see a threaded rod, it’s spiral.

We stock OEM Mr-Glass balances when available, but we also carry quality aftermarket equivalents from Caldwell and Amesbury that match the weight range exactly. The aftermarket units are typically $18 – $35 per pair cheaper, and in Jacksonville’s humidity they hold up just as well. We’ll tell you the difference, quote both, and let you choose. One note for transparency: Meridian Windows and Doors Jacksonville is an independent installer and repair provider, not a Mr-Glass factory outlet. We’re authorized to install their products and we stock Mr-Glass-compatible parts, but we’re not owned by or affiliated with the manufacturer.

Signs Your Mr-Glass Window Replacement Is Failing

• The sash won’t stay up. This is almost always the balance. The spring loses tension over time, and the shoe that locks into the frame wears down. In Jacksonville’s coastal air, mild corrosion on the metal shoe accelerates the wear.
• Fog or moisture between two panes. Your insulated glass unit has lost its seal. The desiccant inside is saturated. Once that happens, the glass cannot be cleaned from the inside. The unit needs replacement, which is standard work for us.
• You hear a pop and the window drops. That’s the balance spring letting go. Don’t force the window open or closed. A failed spring can let the sash drop suddenly onto fingers.
• The lock doesn’t line up or won’t latch. Over years, the sash settles slightly. The keeper and latch fall out of alignment. Sometimes it’s an adjustment. Sometimes the latch itself has a broken internal cam.
• Drafts you can feel with your hand around the frame. This is weatherstripping compression set, common on Mr-Glass windows ten years or older. The pile or foam seal flattens and stops sealing. Replacement weatherstripping is cheap and fast.

Replacement Cost & What’s Included

In Jacksonville, a single Mr-Glass window sash replacement typically runs $240 – $480 installed. Here’s the breakdown that moves the number:

• Glass only (insulated unit): $140 – $260 installed. Two-pane, low-E, argon-filled. Single-sash removal and reglaze on site.
• Balance replacement (pair): $95 – $160 installed. Includes new shoes, adjusted to the sash weight.
• Tilt latch or lock set: $50 – $90 installed. OEM or equivalent.
• Full sash replacement (frame kept): $320 – $480. If the sash vinyl is cracked or warped, this is the cleaner fix than glass-only.

The price you’re quoted is written down before any work starts. That covers the part, the labor, the cleanup, and the written 365-day guarantee. If the repair fails within that year, we come back at no charge. That’s not a verbal promise. It’s in the work order.

DIY or Call Us?

Some things you can safely check yourself. Confirm whether the balance is block-and-tackle or spiral by looking at the side channel. Pop the tilt latches and pull the sash in to inspect the glass thickness with a tape measure. Write down what the sticker says. That’s useful information for our quote. What we don’t recommend is replacing a block-and-tackle balance on your own. It is under tension, and the shoe carrier has to be released in the right sequence inside a narrow channel. A slip there can send the carrier into your hand or crack the vinyl jamb. We’ve repaired enough homeowner attempts to say this plainly: call us. We do the part swap safely, in under two hours, for the fixed price on the quote. Call (904) 513-9670 and we’ll schedule a time that works, not a four-hour window.
