Mr-Glass Energy-Efficient Windows in Miami: What to Know First
We repair and replace Mr-Glass energy-efficient windows throughout Miami, and most jobs are done in a single visit. You’ll get a written line-item quote before any work begins, with both warranty layers registered in writing before our truck leaves your driveway. If you own a Mr-Glass window that’s fogged, drafty, or letting UV light fade your floors, call (561) 489-4036 and a live person will answer. That’s not a callback service. That’s us.

This page is for Miami homeowners who bought Mr-Glass windows years ago and are now watching the energy bills climb or the glass cloud up. We’re an independent Mr-Glass service provider, not a factory warranty arm. That matters, because we tell you what’s actually wrong, not what the manufacturer’s script says to say.
How Mr-Glass Products Fail - and How We Fix Them
Every window line has its habits. Mr-Glass is no different. Here’s what we see in Miami homes, week after week:
- Seal failure on the Mr-Glass 6000 Series double-pane units. The desiccant strip inside the spacer eventually saturates in Miami’s humidity, and once it does, the argon leaks out and the glass fogs from the inside. You can’t wipe it off because it’s between the panes. We replace the insulated glass unit (IGU), not the whole frame, unless the frame is also compromised.
- Low-E coating degradation on south-facing Mr-Glass picture windows. Miami sun is relentless, and after eight to twelve years the metallic oxide coating on the interior glass surface starts to develop a hazy, blotchy film. It looks like hard water stains that never go away. The fix is a new IGU with a current-generation Low-E coating rated for South Florida’s solar load, not a film patch.
- Frame warping on Mr-Glass vinyl sliders exposed to western afternoon heat. Vinyl expands and contracts. In Miami, west-facing windows can see surface temperatures above 140°F in July. Over time, the frame corners on Mr-Glass sliders can twist enough that the sash no longer seats flush against the weatherstripping, which lets conditioned air bleed out. We re-square the opening, reset the frame, and replace the weatherstripping with a higher-durometer material.
- Condensation between panes on Mr-Glass casement windows near the coast. Brickell, Coconut Grove, Coral Gables, anywhere within a mile of Biscayne Bay, salt air is a factor. The seals on older Mr-Glass casements fail faster near saltwater. If you see moisture inside the glass after a cold front in January, that’s seal failure. We replace the IGU and can upgrade to insulated laminated glass for better sound control and impact resistance.
- UV fade on Mr-Glass single-pane storm windows still in service. Some Miami homes still have original Mr-Glass single-pane units, especially in mid-century neighborhoods like Shenandoah and Morningside. Single pane blocks almost zero UV. Faded hardwood floors, bleached upholstery, and warm spots near the glass are the telltale signs. We replace these with ENERGY STAR-rated double-pane units and the difference in room temperature is noticeable the same afternoon.
Our Mr-Glass Energy-Efficient Windows Process
We’ve been doing this long enough to know that rushing a window job creates problems that show up in July. Here’s how a Mr-Glass replacement or repair goes with us:
- 1
You call (561) 489-4036. A person picks up. We ask what you’re seeing, when it started, and which direction the window faces. That last question tells us a lot in Miami’s climate.
- 2
We measure every opening twice. Dale Kessler reads a rough opening before he ever orders glass. If the rough opening is out of square by even a quarter inch, the new unit will bind. We catch that before we order.
- 3
We quote manufacturer lines side by side on paper. If your Mr-Glass frame is sound, we quote a direct replacement IGU. If you’re done with Mr-Glass, we also quote PGT, CGI, CWS, and ES Windows options, so you see the price difference in writing before you decide.
- 4
We do the work in one visit. The old unit comes out, the new IGU goes in, and the opening is re-flashed and sealed. We use backer rod and elastomeric sealant rated for South Florida humidity and salt exposure.
- 5
We test before we leave. We run a smoke pencil along the perimeter to check for air leakage. If it pulls smoke, it’s not done right. If the pane is not true, the job is not done.
- 6
We register both warranty layers in writing. You get the manufacturer’s IGU warranty and our workmanship warranty, durations stated, on paper, before the truck pulls away. That’s the Keystone Standard.
What Mr-Glass Energy-Efficient Windows Cost in Miami
Here’s straight pricing for common Mr-Glass jobs in Miami, typical as of 2025:
- Replace a fogged IGU in a Mr-Glass 6000 Series double-hung: $385-$640 per pane, depending on glass size and Low-E spec.
- Replace a Mr-Glass picture window IGU with UV-blocking Low-E glass: $550-$950 per pane.
- Full replacement of a Mr-Glass vinyl slider with a PGT or ES Windows energy-efficient unit: $1,400-$2,800 installed, depending on size and impact rating.
- Window energy audit for a full home: $225-$400, applied as a credit toward any work you book with us afterward.
What moves the price: glass square footage, whether the frame needs re-squaring, accessibility on upper floors, and whether you want laminated glass for storm protection. We don’t pad the bill. We don’t add surprise line items. A square deal means the quote is the price. Call (561) 489-4036 for a free estimate.
Why Miami Homeowners Call TruePane Windows & Doors for Mr-Glass Work
We’ve served Miami for over 42 years, and Dale Kessler has been running TruePane since 2008 on a rule his father taught him in a two-bay glazing shop in Columbus, Ohio: measure twice, order once, and put everything in writing. That’s how we work. Every tech who walks into your home is background-checked and uniformed. Every job carries the 90-Day Done Right Promise. If it’s not done right, we make it right, no paperwork fights, no arguing. And because we’re authorized installers for more than a dozen lines including PGT, CGI, CWS, and ES Windows, we’re never stuck trying to sell you a brand we only carry because it was in stock. When a Mr-Glass window isn’t worth repairing, we’ll tell you that and show you what we’d put in its place.
FAQs
In most cases we can replace just the insulated glass unit, keeping your existing Mr-Glass frame in place. That runs $385 to $640 per pane on a typical 6000 Series double-hung. If the frame is warped or leaking, full replacement makes more sense, and we’ll show you both numbers side by side before you decide. Call (561) 489-4036 and we’ll give you a straight answer.
If your original warranty period is still active, using aftermarket glass could affect any remaining factory coverage. We’ll check the dates on your paperwork and tell you honestly what’s covered before we touch anything. Our workmanship warranty is separate and written, with durations stated, so you’re covered either way.
Some original Mr-Glass hardware, like locking mechanisms and hinge sets, has been discontinued. We keep common aftermarket equivalents in stock and know which ones actually fit without modification. For glass, we order each IGU to spec from our local fabricator, so availability is rarely an issue. That’s one reason most Mr-Glass repairs here are done in a single visit.
We schedule most repair and replacement jobs within the same week, and most are completed in one visit. Miami’s hurricane season does fill our calendar, so if you need work before June, call sooner rather than later at (561) 489-4036. We’ll be there when we say.
If your frames are square and the hardware works, replacing the glass is the most sensible money you can spend. If the frames are failing, we sell you something better, and we quote PGT, CGI, CWS, and ES Windows side by side so you see exactly what you’re buying. Either way, you’ll get a written quote, and the price on that quote is the price we stand behind.
