Mr-Glass Window Replacement: The Olympia Heights Owner’s Guide
Mr-Glass window replacement in Olympia Heights typically runs $340-$780 per opening installed, depending on whether you’re swapping a single-hung sash, a full frame, or an impact-rated unit. We stock Mr-Glass-compatible hardware, balances, and sash assemblies on our trucks, and most replacements we measure in the morning are installed by afternoon. Most Olympia Heights owners discover the problem when a window won’t stay open, won’t lock, or shows visible moisture between the panes - usually after a storm season or during the first cool snap when they try to ventilate the house.
Which Mr-Glass Models This Applies To

Mr-Glass produces several window lines common in South Florida builds from 2015 onward: the MG-200 single-hung series, MG-300 horizontal roller, MG-500 fixed picture units, and the MG-700 impact-rated line. The label you’re looking for is a small etched mark on the glass spacer or a foil sticker on the frame edge, usually showing “MG-” followed by the series number and a date code. If the label’s sun-faded, measure the visible glass width and height to the nearest 1/8 inch, plus the frame depth - we’ll cross-reference against Mr-Glass’s published spec sheets.
We are an independent service provider; we are not affiliated with Mr-Glass. For most Olympia Heights jobs, we source OEM Mr-Glass parts direct from the manufacturer’s Miami distribution point. In some cases - particularly for discontinued MG-200 balances or obsolete lock mechanisms - we spec quality aftermarket equivalents that match the original operating force and corrosion resistance. The aftermarket decision is always documented on your written quote, not made at the truck. One compatibility gotcha we’ve hit repeatedly: the MG-300 roller uses a 1-1/4 inch wheel in post-2019 production, but pre-2019 units shipped with 1-inch wheels. The housings look identical until you pull the sash.
Before
AfterSigns Your Mr-Glass Window Replacement Is Failing
- The sash drops or won’t stay open. This points to a failed balance system - the coil spring or block-and-tackle inside the frame jamb has lost tension. In Olympia Heights, we see this accelerate after salt-air exposure near the Bird Road corridor, where the balance housing corrodes faster than inland installs.
- Visible fog or moisture between glass panes. The insulated glass unit (IGU) seal has failed, breaking the argon fill and allowing condensation. Once the desiccant inside the spacer saturates, the clouding is permanent; the IGU needs replacement, not cleaning.
- The lock won’t engage or feels sloppy. Either the keep is misaligned from frame settlement, or the lock mechanism itself has worn cam lobes. We’ve found MG-500 series locks particularly sensitive to frame racking in older stucco openings.
- Rolling sash grinds, jumps, or sticks. The roller wheels are flat-spotted or the axle bearings are packed with grit. On MG-300 units, the track itself can deform if the sash has been forced past an obstruction.
- Draft or water intrusion at the sill. The weatherstrip has compressed past recovery, or the sill track drain holes are blocked. In Olympia Heights, weep-hole clogs from pollen and gecko nests are more common than owners expect - a five-minute clear versus a full replacement if water has rotted the subsill.
Replacement Cost & What’s Included

| Component | Typical Range (Installed) |
|---|---|
| Balance / coil spring replacement (MG-200/300) | $180 - $290 |
| Insulated glass unit (IGU) swap, standard size | $340 - $520 |
| Full sash assembly (glass + frame) | $480 - $680 |
| Complete frame-out replacement, standard opening | $620 - $780 |
| Impact-rated unit replacement (MG-700 series) | $720 - $1,150 |
What drives the range: size, whether the opening needs reframing, and whether we’re matching existing trim or installing new. Every quote we write in Olympia Heights includes the measured survey you keep, the part specification, labor, disposal of the old unit, and the photo record we deliver at completion. The written price before any work starts - Haven Clause 1 - means the number on your quote is the number on your invoice. No change orders unless you change the scope. The 365-Day Done Right Promise covers the installation; manufacturer defects fall to Mr-Glass’s original warranty, which we help you file if needed.
DIY or Call Us?
There are two things an Olympia Heights owner can safely check before calling: clear the weep holes with a pipe cleaner, and verify the lock misalignment isn’t just a loose screw. Beyond that, Mr-Glass window replacement involves tempered or laminated glass that can weigh 40-90 pounds per sash, and impact-rated units carry even more mass. The balance systems are under tension; releasing them without a winding tool risks the sash dropping on your hand or the balance snapping free. We don’t recommend DIY on these.
When we arrive, we measure the rough opening, photograph the existing installation, and give you the written price before any tool is lifted. If you’ve already got a quote from another installer, bring it - we offer a free second opinion on any written estimate. Call (786) 400-2761 to schedule your free estimate.
FAQs

Mr-Glass units in Olympia Heights typically deliver 15-22 years of service before major component failure, with impact-rated lines tending toward the longer end. The limiting factor is usually the IGU seal or balance corrosion, not the frame itself. Call (786) 400-2761 for an exact quote on your specific unit - estimates are free.
A cracked or broken pane cannot be repaired; the IGU must be replaced as a sealed assembly. Fogging between panes is also irreversible once the desiccant saturates. Call (786) 400-2761 for an exact quote - estimates are free.
A standard sash or IGU replacement takes 45-90 minutes per opening; a full frame-out runs 2-3 hours. We schedule by the job, not by the hour, so the crew isn’t rushing to the next call. Call (786) 400-2761 to schedule your free estimate.
We stock common MG-200 and MG-300 balances, locks, and rollers on our trucks, and we maintain a running inventory of standard-size IGUs at our Miami distribution point. Specialty or oversized impact units typically arrive within 48 hours. Call (786) 400-2761 to confirm availability for your model - estimates are free.
Sonia Raman and her crew have logged steady work throughout Olympia Heights, including jobs near the Bird Road corridor, long enough to know which Mr-Glass frame profiles hold up through a South Florida summer and which ones don’t make it to the second rainy season. She still measures every rough opening before quoting it, which keeps her change-order count close to zero. As she puts it: “Measure it right the first time. Everything after that is just paperwork.”
