Mr-Glass Door Installation: The West Park Owner’s Guide

Mr-Glass door installation in West Park typically runs $1,800-$4,200 for a standard single entry unit, depending on whether you’re replacing an existing frame or cutting a new opening into block or frame construction. We stock Mr-Glass hardware and installation kits for same-day starts on most residential series, and every job ships with the written price before work begins and a documented photo record when it finishes. Most West Park homeowners find us after noticing their door isn’t sealing, the multipoint lock won’t engage, or they can see daylight around the jamb after years of South Florida sun warping the composite.

Which Mr-Glass Models This Applies To

Mr-Glass produces three residential door lines that circulate in West Park: the MG-100 Impact Entry series, the MG-200 Thermally Broken line, and the MG-300 Decorative Lite collection. The MG-100 and MG-200 share the same 4-9/16″ jamb depth and multipoint locking hardware, which means we can often cross-match components when a specific color or finish is backordered. The MG-300 uses a narrower 3-5/8″ jamb and proprietary hinge spacing that won’t accept standard retrofits without machining.

To identify your series, check the etched mark on the glass corner or the sticker on the hinge side of the jamb. If the sticker’s worn off, measure the jamb depth and the distance between the top hinge and the deadbolt bore. MG-100/200 units run 8″ on center; MG-300 runs 7-1/2″. We carry both OEM Mr-Glass hardware and tested equivalents from Amesbury and Hoppe that meet the same Miami-Dade impact ratings. For West Park homes built between 2005 and 2015, we regularly see MG-100 units with the early-generation sweep design that Mr-Glass revised in 2016. The old sweep channel is 1-3/8″ wide; the current spec is 1-1/2″. Installing the wrong width leaves a gap that passes inspection but fails in a driving rain.

Signs Your Mr-Glass Door Installation Is Failing

• Visible light around the jamb or sill. This usually means the door has dropped on its hinges or the composite frame has bowed from heat cycling. In West Park, unshaded south-facing entries can see frame temperatures above 140°F in July, which compresses the weatherstrip set and loosens the screw seating in vinyl or wood jambs.
• The multipoint lock won’t throw or the handle spins without resistance. The gearbox inside the lock mechanism has stripped, often from homeowners forcing the handle when the door is out of alignment. MG-100 and MG-200 gearboxes are replaceable separately from the full multipoint system, which saves roughly $340 over a full lock replacement.
• Water staining at the base of the interior jamb. The sill pan or end dams have failed, or the sweep has worn past its compression limit. On slab-on-grade homes common in West Park’s 33023 corridor, this shows up first as efflorescence on the interior baseboard.
• The door sticks seasonally but frees up in cooler months. This is classic thermal expansion in an improperly shimmed frame. The gap between the rough opening and the jamb was packed with foam but not mechanically shimmed, so the frame moves with temperature while the block wall doesn’t.
• Glass fog between the panes on a decorative lite unit. The IGUs in MG-300 doors use a stainless spacer that holds up better than aluminum in our humidity, but the sealant still degrades. Once the desiccant saturates, the glass unit is done. It cannot be disassembled and resealed to factory spec in the field.

Replacement Cost & What’s Included

The range depends on three factors: whether the rough opening is plumb and square (most in West Park’s 1960s-1980s stock are not), whether the wall is block or frame construction, and whether the existing impact rating must be maintained for insurance or code compliance. Our quote includes the measured survey you keep, the written scope with line-item pricing, permit pulling if required, and the documented photo record. The 365-Day Done Right Promise covers labor and installation materials; manufacturer defects are handled through Mr-Glass directly.

DIY or Call Us?

There’s a short list of checks any owner can make safely. Verify the door is actually out of square with a 4-foot level on the jamb. Look for missing or cracked screw covers on the hinges, which indicate someone’s already tried adjusting and may have stripped the mounting. Check whether the threshold screws are loose or corroded, common in West Park homes within a quarter-mile of the Intracoastal where salt air accelerates galvanic corrosion.

Where DIY goes wrong is in the adjustment itself. A Mr-Glass impact door weighs 85-120 pounds depending on lite size, and the multipoint lock mechanism is under spring tension. Improper shimming transfers load to the lock points and warps the keepers. We’ve replaced three doors in the past two years where the homeowner’s adjustment cracked the composite jamb at the deadbolt bore. Measure it right, say what it costs, do the work.
