Mr-Glass Door Installation: The Clewiston Owner’s Guide

Mr-Glass door installation in Clewiston typically runs $1,800-$4,200 for a standard single entry unit, depending on the series and whether the opening needs reframing. We stock Mr-Glass-compatible hardware and seal kits on our trucks, and most installs are completed in a single day once the measured survey is approved. Most Clewiston owners realize their Mr-Glass door is failing when the sweep starts dragging, the multipoint lock won’t seat, or they feel air moving through the jamb during one of our summer thunderstorms.

Which Mr-Glass Models This Applies To

Mr-Glass produces three residential door series that circulate in the Clewiston market: the MG-100 Impact Entry, the MG-200 Thermally Broken, and the MG-300 Multi-Slide Patio. The model label is stamped on the hinge edge of the door slab, usually 18 inches from the top, and begins with the series prefix followed by a six-digit date code. We need that code to match the jamb width exactly, Mr-Glass shifted from 4-9/16″ to 5-1/4″ nominal jamb depths in 2019, and using the wrong shim pack leaves a gap that our humidity will find within two seasons.

For hardware, we stock OEM multipoint lock sets and adjustable hinges for all three series. Aftermarket equivalents exist from Truth and Hoppe, but we default to OEM on Mr-Glass because the striker spacing is proprietary at 45mm centers, not the 40mm or 55mm that aftermarket templates assume. We’ve pulled frames in Clewiston where a previous installer forced a generic multipoint and the latch bolts had worn oval slots into the keepers within three years. The OEM part costs more upfront. The math works.

Signs Your Mr-Glass Door Installation Is Failing

• The door sticks at the top corner in summer, then gaps in winter. This is jamb movement from seasonal humidity cycling, common in Clewiston’s sugarcane-country climate. The composite jamb material Mr-Glass uses resists rot but still expands; if the original install didn’t leave proper reveal, the slab binds against the head jamb by August.
• Water pools on the sill after a hard rain, even with the door closed. The adjustable sill cap on MG-100 and MG-200 series has a weep system that clogs with pollen and cane-field dust. Cleaning helps, but if the sill pan was never bedded in sealant during original install, water finds the subfloor anyway.
• The multipoint lock handle lifts but the bolts don’t retract fully. The gearbox wears where the spindle passes through, especially on south and west exposures where afternoon sun heats the metal. MG-300 series uses a different gearbox geometry than the entry doors; we’ve seen Clewiston homeowners order the wrong part twice before calling.
• Daylight visible between the door bottom and the sweep. The adjustable sweep on MG-series doors has a wear strip that drops over time. Owners crank the adjustment screws until the strip drags, which burns the motor on an automated opener if one is fitted.
• The fixed panel of a French door unit rattles in wind. The T-astragal seal compresses permanently after about seven years in Florida UV. Mr-Glass changed astragal profiles in 2021; the new part is not backward-compatible without replacing the full meeting stile assembly.

Replacement Cost & What’s Included

For a standard Mr-Glass entry door replacement in Clewiston, our installed pricing breaks down as follows:

What moves the number: jamb depth, whether the rough opening is plumb (many in Clewiston’s 1970s-1990s housing stock are not), and whether we need to match an existing impact rating for HOA compliance. Every quote is the measured survey you keep; the final invoice matches it under Haven Clause 1. Our 365-Day Done Right Promise covers labor and installation materials. Product warranties run through Mr-Glass directly and vary by series; we document your registration as part of the photo record.

DIY or Call Us?

There’s a short list of checks that won’t make things worse. Verify the model stamp. Photograph the label. Run your hand along the jamb on a windy day to find the leak path. Clear the sill weeps with a pipe cleaner. Beyond that, door installation involves shimming a hundred-pound slab to 1/8″ tolerance while it’s swinging, then tuning a multipoint lock so the compression seal seats evenly top to bottom. Get the shim sequence wrong and the deadbolt binds; get the lock timing wrong and the thermal seal fails in six months. We’ve reframed openings in Clewiston where a homeowner’s helper leaned the slab wrong and cracked the hinge mortise clean through the jamb. Measure it right the first time. Everything after that is just paperwork. For the part match and the install, call (863) 509-1135.
