Mr-Glass Door Installation: The Kendall Owner’s Guide
Mr-Glass door installation in Kendall typically runs $1,200-$2,800 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 carry the full series catalog on our tablets, so most installs begin within 3-5 business days of your measured survey. Most Kendall owners discover their Mr-Glass door needs attention when the multipoint lock stops engaging evenly, the sweep drags on the threshold, or they notice daylight between the frame and the jamb after a storm.
Which Mr-Glass Models This Applies To
Mr-Glass organizes its door lines by application and impact rating, not by a single model year. The series you’ll encounter in Kendall are the MG-Impact Entry (fiberglass and steel slab options), MG-Patio Slider (two-panel and four-panel configurations), and MG-French (outward-swinging with multipoint hardware). The critical compatibility gotcha: MG-Impact Entry doors manufactured before 2019 used a 1-3/4 inch slab thickness with a proprietary mortise pocket spacing that does not accept standard 2-1/4 inch retrofits without frame modification. Check the hinge side of your door for a white adhesive label with the series prefix and a six-digit date code; if the code starts with 18 or lower, call us before ordering anything.
For OEM versus quality aftermarket, Mr-Glass multipoint locks and hinges are proprietary to their track system. We source direct from Mr-Glass for lock bodies, deadbolts, and hinge assemblies. Aftermarket options exist for sweeps, weatherstrip, and thresholds, but we specify OEM on anything that carries the impact rating, because a non-listed replacement voids the HVHZ certification. We also stock PGT, CGI, and CWS hardware on the truck, which matters when your opening can accept a different manufacturer and you want to compare performance tiers side by side.
Signs Your Mr-Glass Door Installation Is Failing

- The multipoint lock only catches at the handle, not the top or bottom bolts. This usually means the keep plates have shifted in the frame, which happens in Kendall when the stucco settles after our wet season. The bolts themselves are fine; the frame needs realignment before the mechanism destroys itself trying to engage.
- Daylight visible at the hinge corner or threshold after closing. The door hasn’t warped. More likely the compression seal has flattened past recovery, or the adjustable threshold screws have backed out from thermal cycling. We see this on west-facing MG-Patio Sliders in Kendall after about six years of afternoon sun.
- The door drags or sticks seasonally, worse in August. Florida humidity swells the jamb legs if the sealant joint behind the brickmould has cracked. It’s not the door; it’s the frame absorbing moisture through a failed perimeter seal. Left alone, the hinges tear out.
- Condensation between the glass lites on an MG-Impact Entry with integrated blinds. The insulated glass unit seal has failed. Mr-Glass uses a dual-seal system, but Kendall’s salt air and UV load push the edge seal at about the 10-12 year mark, sooner if the door faces Biscayne Bay directly.
- The sweep tears or the threshold corrodes at the screw holes. Normal wear, accelerated by our sandy soil and pressure-washing habits. The part is replaceable, but the threshold type changed in 2021; older MG series used an aluminum extrusion that is now back-ordered, so we verify stock before scheduling.

What drives the range: block versus frame construction, whether the stucco needs patching, and if the existing frame is square within 1/8 inch. Our measured survey gives you the fixed price. The quote you sign is the invoice you pay. Parts carry the manufacturer’s warranty; our labor carries the 365-Day Done Right Promise under the Haven Standard. We pull permits when the scope requires it, and we pass inspection before we invoice.
DIY or Call Us?

There’s a short list of checks any owner can make safely. Verify the lock engages smoothly with the door held open, which isolates frame stress from mechanism wear. Look for the white Mr-Glass label and photograph it. Check the threshold adjustment screws with a Phillips head, but stop if they strip, because the aluminum threads are soft.
Where DIY goes wrong: adjusting a multipoint lock without a laser plumb line usually makes the misalignment worse. Removing an impact-rated door from its hinges solo risks tearing the jamb or dropping the slab. And cutting stucco to access a frame without knowing what’s behind it, you’re gambling with electrical and plumbing penetrations. We’re not saying you’re incapable. We’re saying the documented photo record we leave is worth more than the Saturday you’d spend guessing. Call (786) 321-3319 and we’ll measure once, document it, then cut.
FAQs
Expect 15-20 years for the fiberglass slab, 10-12 for the insulated glass seal, and 6-8 for the compression weatherstrip if the door faces west or south. Salt exposure within a mile of Biscayne Bay pulls those numbers down by about 20 percent. Call (786) 321-3319 for an exact condition check, estimates are free.
Sometimes. If the issue is a misaligned keep plate or a loose connecting rod, we adjust and document it. If the gearbox has cracked or the deadbolt cam is worn, repair costs approach replacement and the part is not rebuildable. We show you both options in writing before any work starts. Call (786) 321-3319 for a free estimate.
Four to six hours for a standard entry door in an existing opening, assuming the frame is sound. New construction or block-wall cuts add a day for rough-opening work and stucco cure. We schedule the inspection before we leave the site. Call (786) 321-3319 to book your measured survey.
We stock multipoint lock bodies, hinges, sweeps, and threshold caps for the current MG series. Slabs and pre-hung units are ordered to your measured survey, because Mr-Glass offers six finish colors and three hardware tones, and we don’t guess at your match. For discontinued series, we verify salvage availability before we quote. Call (786) 321-3319 to confirm compatibility.
