We provide independent Mr-Glass energy-efficient window service across Miami Beach, from glass replacement and seal repair to full ENERGY STAR upgrades.

This page is for Mr-Glass owners who want their windows to actually hold up against Miami Beach sun, salt air, and humidity, not just get patched and painted over. Call (863) 656-0462 and a live person answers, any hour.
How Mr-Glass Products Fail - and How We Fix Them
Mr-Glass makes a solid window, but Miami Beach does things to glazing that showrooms in other states never see. Here’s what we actually find when we pull one apart:
- Seal failure on Mr-Glass insulated glass units (IGUs). The dual-pane Low-E units Mr-Glass fits into their aluminum and vinyl lines eventually lose their edge seal in salt-heavy air. You’ll see fogging or a milky haze between the panes that never wipes off. That haze means the argon gas fill has escaped and the Low-E coating is no longer doing its job. We replace the IGU with a fresh Mr-Glass-spec unit and confirm the argon fill with a glass analyzer before it leaves our shop.
- Low-E coating degradation on oceanfront units. Condos along Collins Avenue and the Faena District see coating breakdown faster than inland homes because salt mist etches the glass surface. The tell is a rainbow sheen or blotchy patches you can’t clean off. We replace the glass, and for oceanfront exposures we recommend Mr-Glass’s laminated Low-E option, which puts the coating on an inner surface where salt air can’t reach it.
- Condensation at the frame of Mr-Glass casement and awning windows. Older Mr-Glass casement lines shipped with a foam tape gasket that shrinks after about eight years of Miami Beach humidity cycles. Water beads inside the glass at the bottom corners, and eventually that moisture wicks into the wall. We pull the sash, replace the gasket with a closed-cell silicone alternative, and realign the hardware so the weatherstripping compresses evenly. That’s a $40 repair rebate eligible job if it’s over $200.
- UV fade complaints on Mr-Glass sliding glass door panels. Here’s a Miami Beach reality the manufacturer won’t tell you: standard clear Mr-Glass panels let in enough UV to bleach hardwood floors and upholstery within two seasons. If your furniture is fading but the glass looks fine, you probably have standard float glass, not Low-E. We can swap that panel for a Mr-Glass-compatible Low-E or solar-tinted unit, and in most cases the frame doesn’t need to come out, which saves you hundreds.
- Warped spacer bars inside Mr-Glass dual-pane units. This one catches people off guard. The aluminum spacer between panes in some Mr-Glass IGUs corrodes from condensation and bows inward, which eventually cracks the seal from the inside. You’ll hear a faint rattle or see the glass bow slightly under pressure. It’s fixable with a replacement IGU using a warm-edge or stainless spacer, and we quote it as a repair, not a full window replacement, unless the frame itself is sprung.
Our Mr-Glass Energy-Efficient Windows Process
Here’s how a Mr-Glass job goes when you call Winslow Windows & Doors:
- 1
Call and talk to a person. You call (863) 656-0462, and a live person picks up. Ed or one of the crew asks what you’re seeing: fog, draft, fade, leak. No phone tree, no ticket number.
- 2
We come out and diagnose. A background-checked technician in uniform shows up at the scheduled time. We identify the exact failure, whether it’s an IGU seal, a gasket, a spacer, or something else. We also check the rest of the window, because on older Mr-Glass units a second issue is often starting.
- 3
We present the parts decision. For Mr-Glass windows still under any warranty-eligible scenario, we use Mr-Glass-spec or OEM-equivalent parts to keep things clean. For older out-of-warranty lines, we may recommend a quality aftermarket IGU that meets or exceeds the original energy rating. We tell you the trade-off in plain language and let you decide. No hidden upcharge.
- 4
We install and test. We remove the old unit, clean the frame channel, seat the new glass, and run a basic thermal check. If it’s a Low-E or argon-filled unit, we verify the gas fill and coating orientation before we call it done.
- 5
We clean up and hand you the invoice. The price on your written quote is the price on the invoice. If something changes, we call you first and get it in writing. No surprises after the fact.
- 6
We stand behind it. Every Mr-Glass window job carries the 36500-Day Done Right Promise. If it’s not done right, we come back and make it right. Ed’s name is on the business, and his name is on every job we do.

FAQs
If your window is still under the original Mr-Glass warranty, using non-OEM parts could affect what the manufacturer covers, and we’re upfront about that. For any window still inside a warranty-eligible period, we use Mr-Glass-spec or OEM-equivalent glass and hardware. Call (863) 656-0462 with your window’s serial number or paperwork, and we’ll tell you exactly where you stand before you spend a dime.
Yes, and in most cases we can improve it. We match the original IGU’s Low-E coating and gas fill, or upgrade you to a better-performing Low-E or laminated unit if your frames allow it. Window Energy Audits & Ratings are part of what we do, so we’ll show you the numbers before we install anything. Call (863) 656-0462 to schedule a free estimate.
Most Mr-Glass-spec IGUs and hardware arrive at our shop within 3 to 5 business days, and we’ll schedule the install as soon as the parts are in. If you need a temporary fix to secure the window while you wait, we’ll handle that on the first visit. Call (863) 656-0462 and we’ll give you an honest timeline, not a vague answer.
If the frame is square, the hardware works, and the only problem is the glass or the seal, a repair makes financial sense almost every time. If the frame is corroded, the sash is sagging, or you’re chasing one leak after another, we’ll tell you that too. An honest second opinion costs you nothing, and if you have a written estimate from another company, we’ll review it free. Call (863) 656-0462.
Yes. We replace fogged, scratched, or underperforming Mr-Glass sliding glass door panels with Low-E and laminated options sized for your exact track. That’s a common job in Miami Beach high-rises, and we’ve done enough of them to know the building access requirements before we show up. Call (863) 656-0462 for a free estimate on your door panel.
