Mr-Glass Windows & Doors in Coral Gables, FL | Winslow Windows & Doors
Winslow Windows & Doors provides independent Mr-Glass service across Coral Gables, from Window Installation in Coral Gables for Series 700 single-hungs to impact-rated vinyl sliders. What makes our work here different is simple: we’re the shop that understands Coral Gables’ Historic Preservation Board won’t let you flatten an arched opening just to fit a stock rectangular unit. So we template the original radius and have the frame fabricated to match, instead of fighting the HPB. If you own Mr-Glass windows or doors in Coral Gables and need repair or replacement, call (904) 478-8983 for a straight answer and a free estimate.
Why Coral Gables Residents Choose Us for Mr-Glass Service
We’ve been servicing Mr-Glass products in Coral Gables long enough to know which units hold up and which ones don’t. Ed Winslow, our owner, grew up a few minutes from the Biltmore Hotel in Coconut Grove and studied building construction technology at Miami Dade College before spending more than two decades focused on window and door replacement across Coral Gables and the surrounding neighborhoods. That means when a Coral Gables homeowner calls about a failed seal on a Series 900 casement, we already know the humidity trapped by the banyan canopy probably accelerated it. We’re not learning on your job. And because we are an independent contractor rather than a manufacturer affiliate, we can tell you honestly when a repair makes sense and when pulling the unit and installing a NOA-compliant replacement is the smarter money.

Common Mr-Glass Windows & Doors Problems We Solve in Coral Gables
- Failed seals in Mr-Glass insulated glass units. Coral Gables’ dense canopy of mature banyan, live oak, and ficus trees keeps humidity pressed against original frames year-round. That constant moisture works its way into the edge seals and you get fog between the panes. We replace the IGU, not the whole sash, whenever the frame is still sound.
- Corrosion at the meeting rails of Mr-Glass aluminum horizontal rollers. Homes built on original coral rock substrate wick moisture up into the rough opening. That’s a Coral Gables-specific condition you won’t see in post-war neighborhoods on slab. The corrosion binds the rollers, and the homeowner starts forcing the sash, which bends the track. We fix the track and replace the rollers with sealed-bearing units.
- Warped or swollen wood sashes on vintage Mr-Glass casements. Decades of humidity and thermal cycling in 1920s Mediterranean Revival homes take a toll. The sash swells, the hinges sag, and the window won’t close tight. In historic districts, we often rebuild the sash in place rather than replace, because the HPB wants that original wood profile kept.
- Jammed rollers and misaligned tracks on Mr-Glass single-hungs. When the block-and-tackle balance fails, the natural instinct is to yank harder. That’s how tracks get bowed. We replace the balances and straighten the track before the frame gets damaged beyond repair.
- Worn weatherstripping on Mr-Glass impact doors. Salt air and daily sun exposure break down the pile and fin seals faster in Coral Gables than inland. You’ll feel the draft and hear the rattle. We replace with OEM-spec weatherstripping so the door operates and seals like it should.
Mr-Glass Service in Coral Gables: What Local Conditions Mean for Your Equipment
The single most important thing to understand about Mr-Glass windows and doors in Coral Gables is that you’re dealing with two masters at once. Miami-Dade’s High-Velocity Hurricane Zone requires every replacement unit to carry a Notice of Acceptance, the strictest hurricane product approval standard in the country. But Coral Gables’ Historic Preservation Board adds a second layer: on contributing structures in the city’s historic districts, any window or door replacement needs design approval. The HPB will reject an impact window permit if a contractor flattens an original arched opening to accommodate a standard rectangular unit, even when that unit is fully NOA-compliant. That’s not a hypothetical. It happens regularly. Our shop keeps standing relationships with fabricators who bend custom Mr-Glass-compatible impact frames to match the original radius. That’s a specialty skill that rarely comes up two miles away in unincorporated Miami-Dade, and it’s the reason a Coral Gables Mr-Glass repair or replacement shouldn’t be handed to a crew that only knows stock sizes. On Alhambra Circle in the Biltmore section, our crew replaced a set of 1940s Mr-Glass wood casements with arched heads that had rotted through at the sills. The HPB required us to keep the exact radius and divided-lite pattern, so we templated the original openings and had custom impact-rated casements fabricated to match, then anchored them into the coral rock jambs with epoxy-set stainless anchors. The project passed HPB review on first submittal and met current NOA standards. That’s the level of care Mr-Glass owners in Coral Gables need, and it’s what we do every week.
Mr-Glass Models & Products We Service in Coral Gables
We service the complete Mr-Glass product line that shows up in Coral Gables homes: the Series 700 single-hung aluminum windows, Series 800 horizontal roller windows, Series 900 casement windows, and the impact-rated vinyl sliding glass doors. When original Mr-Glass parts are available and cost-effective, we use them. When a component is discontinued or on a slow ship from the manufacturer, we source aftermarket balances, rollers, and weatherstripping that meet or exceed the original spec. For pre-2000 Mr-Glass units with frame rot or serious corrosion, we typically recommend full replacement with our Impact Windows in Coral Gables rather than repeated patch repairs. In Coral Gables’ HVHZ, a patched-up old frame is a liability, not a solution. Our local stock of common Mr-Glass hardware keeps turnaround fast for Coral Gables homeowners, because we’re already on the ground here, not dispatching from a warehouse three counties north.
Mr-Glass Service Pricing in Coral Gables
What you’ll pay for Mr-Glass service in Coral Gables depends on what the unit needs. A simple roller replacement on a Series 800 horizontal runs on the lower end, while a full sash rebuild on a 1920s wood casement costs more because the labor is genuinely more involved. Sealed IGU replacements fall in between. The coral rock substrate in many older Coral Gables homes adds anchoring time compared to poured concrete, and that’s part of any honest estimate. A custom arched impact casement with HPB-required divided lites is the most expensive scenario, because the fabrication is bespoke, not off a shelf. Every estimate we give is free and written line-item, so you’ll see exactly where the money goes before we touch a single screw. Call (904) 478-8983 and we’ll walk the job with you, no pressure and no vague numbers.

FAQs - Mr-Glass Windows & Doors in Coral Gables
Yes. We template the existing arched opening, have the replacement casements fabricated to match that exact radius and divided-lite pattern, and submit the job to the HPB with the NOA documentation attached. We’ve done this on Alhambra Circle and throughout the Biltmore section, and we know what the board’s reviewers look for. Call (904) 478-8983 for an exact quote on your specific openings.
It depends on the extent of the corrosion and the condition of the frame. If the track corrosion is localized and the frame is otherwise sound, we can replace the track and rollers for a reasonable cost. If the corrosion has spread into the frame corners or the IGU seals are gone too, replacement usually makes more sense, especially in Coral Gables where you’ll need NOA-compliant impact rating anyway. We’ll give you both numbers and let you decide. Estimates are free.
You need HPB design approval if the home is a contributing structure in one of Coral Gables’ historic districts, and most 1920s Mediterranean homes are. The board cares about the door’s sightlines, frame material, and how closely the replacement matches the original appearance. We handle the HPB submittal as part of the job, so you’re not left to figure out the paperwork alone.
Yes, we do it regularly. Coral rock anchoring is more labor-intensive than anchoring into CMU block or poured concrete, because the substrate is softer and less uniform. We use epoxy-set stainless anchors and longer fasteners to get a solid, code-compliant attachment. It takes more time on the drill, but the finished install is just as strong as any new-construction opening.
Mr-Glass impact windows use laminated glass similar to other major impact brands, so the noise reduction on a busy Coral Gables street is comparable. The bigger variable is the frame seal and installation quality. A poorly installed impact window with gaps at the sill will leak sound no matter how good the glass is. We install to a standard that keeps the noise on the outside where it belongs. Call (904) 478-8983 to talk through your specific street and window situation.
