AfterMr-Glass Window Replacement: The Miami Owner’s Guide
Replacing a failed Mr-Glass window in Miami typically runs between $550 and $1,450 per window installed, depending on size, series, and whether you need impact-rated glass. We stock common Mr-Glass-compatible replacement sashes, insulated glass units, and hardware on our trucks and can usually complete the swap same-day once we’ve confirmed your model. Most Miami owners discover a problem the hard way: a window that won’t close flush after a storm, condensation you can’t wipe off because it’s trapped between the panes, or a frame corner that’s started to sag enough to let afternoon rain leak onto the sill.
We’re Winslow Windows & Doors, an independent local installer in Miami, and we’ve worked on Mr-Glass windows for over a decade. We’re not affiliated with the Mr-Glass corporation. What we offer is direct experience with their product line, honest pricing, and a warranty backed by Ed Winslow’s name on the door.
Which Mr-Glass Models This Applies To
Mr-Glass has produced several window series over the years in Florida, and compatibility is the one thing you cannot guess at. The most common replacement needs we see are insulated glass units for their horizontal roller and single-hung aluminum series, plus hardware kits for casement operators that corrode faster in Miami’s salt air.
Here’s the compatibility gotcha that trips up Miami homeowners: Mr-Glass changed their aluminum extrusion profile about 12 years ago, and the older frames use a narrower glass pack than the newer ones. A replacement sash off the newer production line will not sit flush in a pre-2012 frame without a retrofit glazing bead. We verify this from the frame’s corner key and the etch codes on the glass before ordering anything.
OEM Mr-Glass parts are the obvious first choice, and if the part is available, that’s what we quote. But when a series is discontinued, we use aftermarket insulated units from Florida glazing suppliers that match the original thickness, tint, and Low-E coating spec. We don’t install generic off-brand glass that shifts the sightline or ignores Miami-Dade wind load requirements. You’ll know exactly which route we’re taking and why before you spend a dollar.
If your window has a small silver sticker on the interior frame edge, that’s your Mr-Glass serial number, and it tells us the series, the production year, and the original glass spec. No sticker? We match by measuring the visible glass, the overall frame, and the cam-lock pattern.
Signs Your Mr-Glass Window Replacement Is Failing
- Fog or moisture between the panes. The desiccant inside the spacer has reached its limit and the seal failed. In Miami’s humidity, this shows up faster than in most climates because the outdoor dew point hangs over 75°F for months at a time. Sealed unit replacement is the fix, not glass cleaning.
- The sash drags or binds when you slide it. Aluminum tracks oxidize, and the nylon shoe or roller at the bottom corner wears flat. On Mr-Glass horizontal sliders, the bottom roller is the sacrificial part. By the time you feel the drag, the roller has usually been running on its bearing race for a while. A new roller set restores the glide without replacing the whole frame.
- You can hear street noise that was never there before. Lost seal compression around the glass or a warped sash channel lets air and sound through. This matters more in Miami where a window isn’t just a view, it’s the first membrane between your living room and a wall of traffic.
- Water collects in the bottom track and spills onto the interior sill during heavy rain. The weep holes may be plugged, or the outer track seal has separated from the reglet. We see this constantly after the afternoon deluges in summer.
- Condensation on the room-side glass every morning. That’s not always a seal failure, but on older aluminum-frame Mr-Glass units, the frame itself conducts enough heat to keep the interior glass surface below dew point. The real fix is often a new insulated unit with a lower U-factor, not just more window treatment.
Replacement Cost & What’s Included
In Miami, a Mr-Glass window replacement job breaks down like this:
- Insulated glass unit only (standard clear or Low-E, non-impact): $220-$410 installed, based on glass size under 40 square feet
- Impact-rated insulated unit (Miami-Dade or Florida Building Code zone): $480-$890 installed
- Full sash replacement with new rollers, cam locks, and weatherstripping: $580-$1,050
- Complete window replacement including the frame and installation flange, plus stucco or drywall touch-up around the rough opening: $900-$2,200 per window
We quote the part and labor separately so you can see the math. The spread in price is mostly glass package type and frame size. A 36×60 impact unit costs more than a 24×36 non-impact because impact glass carries a thicker PVB interlayer and requires stouter glazing. We don’t hit you with change orders because of a surprise corner. If the job is quoted as a sash replacement, the sash price holds.
Every job carries a written workmanship warranty through us. We also use the same written warranty policy for the glass itself, and we tell you up front which parts are covered by the unit manufacturer’s original warranty versus what Winslow covers directly. PGT, CGI, and CWS owners get the same treatment when we do replacement work on those brands.
DIY or Call Us?
A window that’s just foggy can be measured and left alone until replacement day. But once you’re into removing sashes or glass stops, there are real risks that cost more than the service call. Glass can weigh forty pounds or more in a single-lite unit. A broken edge during removal is a clean-out job nobody plans on. If the window sits above the first floor, a dropped pane does real damage to the people and property below. For any impact-rated Mr-Glass window, the glazing bead is intended to stay put under design pressure, and prying it out correctly takes the right thin-blade tools and some practice.
Also keep in mind: if you’re in a coastal Miami zip code and you swap a structural window improperly, your insurance carrier can have a lot to say about it after the next storm. For anything more than inspecting and cleaning the track, call us at (863) 946-5039. We’ll send a tech out, confirm what actually failed, and give you a written price before any work starts. If we’re already at your house and the repair is straightforward, we often finish it the same visit.
FAQs
The frame can last 25 years or more if it’s not in direct salt spray. The sealed glass unit typically lasts 8 to 15 years in Miami’s heat and humidity before fog or seal failure shows up. Coastal exposure shortens that span because salt accelerates oxidation on aluminum frames and vinyl glazing beads.
If your Mr-Glass windows are past 12 years old, replacement of the insulated units now will cost less than dealing with a batch of failures all at once later. Call (863) 946-5039 to find out whether your window is a candidate for a glass-only fix.
Sometimes. Rollers, handles, and weatherstripping are replaceable parts that restore function for a fraction of full window replacement. Fogged or cracked glass, on the other hand, means the sealed unit is done. We never patch a seal or drill-and-fill a failed unit; it’s a short-term look-fix that leaks down the road.
Bring us the symptom and we’ll tell you straight whether it’s a $40 roller or a $500 glass package. Call (863) 946-5039 and we’ll talk through what you’re seeing.
A standard insulated glass or sash replacement on a Mr-Glass window takes between 45 minutes and two hours per window, depending on access and whether trim or stucco work is needed. Impact replacements sometimes run longer because the setting blocks and glazing bead tolerances are tighter. Most single-window jobs are done the same day we begin.
Call (863) 946-5039 to schedule a time that works, and we’ll confirm how long your specific job should take.
We stock the most-common replacement rollers, cam locks, weatherstripping profiles, and standard Low-E insulated glass sizes on our trucks. Non-stock impact units and odd-sized custom glass are ordered from our Miami suppliers and usually arrive in three to five business days. If you’re in a pinch and the window is a security issue, we’ll board it properly until the replacement arrives, and that cost is credited toward the replacement work.
We’re Winslow Windows & Doors, an independent installer in Miami, not a Mr-Glass dealer. That’s why we stock what actually fails, not what’s easiest to sell. Call (863) 946-5039 for a free estimate over the phone.
