Mr-Glass Impact Garage Doors: The Lauderdale Lakes Owner’s Guide

We stock and install Mr-Glass-compatible impact garage doors in Lauderdale Lakes, with typical installed pricing from $2,800 to $5,400 depending on door size, wind-load rating, and whether the track and hardware need replacement. Most Mr-Glass impact garage doors we service in Lauderdale Lakes are 8- to 10-year-old aluminum or steel-core models originally installed between 2015 and 2018, and we carry the common torsion spring assemblies, bottom weatherseals, and impact-rated panel sections on our trucks. Homeowners usually discover the failure when the door won’t stay open, drops unevenly, or when they spot daylight under the bottom seal after a storm - the spring has lost tension, the cable has frayed, or the impact glazing seal has separated from the frame.

Which Mr-Glass Models This Applies To

Mr-Glass impact garage doors fall into three series lines: the 300 Series (non-insulated aluminum, common in Lauderdale Lakes townhomes built 2012-2017), the 500 Series (steel-core with polyurethane fill, heavier and more wind-resistant), and the 700 Series (full-view aluminum with impact-rated glass panels, mostly seen in modern infill construction west of State Road 7). The model sticker is on the interior face of the bottom section, left-hand side - it’ll read “MG-3xx,” “MG-5xx,” or “MG-7xx” followed by a width-height code like “16×7.”

The critical compatibility gotcha: Mr-Glass changed its torsion spring wire gauge in 2019. Pre-2019 500 Series doors use 0.250-inch wire; post-2019 use 0.262-inch. The cones look identical, but the wrong spring will over-torque and fail in 18 months. We measure spring length, inner diameter, and wire gauge with a caliper on every Lauderdale Lakes job - if the measurement isn’t written down, it doesn’t exist.

For OEM versus aftermarket: Mr-Glass OEM springs and cables carry a 3-year manufacturer defect warranty but run 30-40% higher. We source equivalent-cycle aftermarket springs from the same Florida foundries that supply Mr-Glass’s tier-2 vendors, with our own 365-Day Done Right Promise backing the installation. For 700 Series glass panels, we use Mr-Glass OEM only - the impact certification is laminated to the specific IG unit, and aftermarket glass voids the wind-load rating.

Signs Your Mr-Glass Impact Garage Door Is Failing

• The door slams shut or won’t stay open above knee height. This is a failed torsion spring or a spring that has lost its set. In Lauderdale Lakes, we see this most often on south-facing doors where the garage hits 95°F+ daily; the spring cycles faster and the metal fatigues in 7-9 years instead of the rated 10,000 cycles.
• The door opens crooked or one side hangs lower. A frayed or snapped lift cable, usually on the side with the direct sun exposure. The cable drum may also be slipping if the set screws weren’t torqued properly at last service.
• Daylight visible under the bottom seal, or water pooling after rain. The rubber or vinyl weatherseal has hardened or torn. Lauderdale Lakes’ summer UV index and the chlorine-rich air from nearby pool equipment accelerates this - we replace these every 3-4 years on average, not the 5-7 you’d expect inland.
• Glass panels rattle or show moisture between the panes. The impact-rated laminated glass has lost its edge seal, or the IG unit’s desiccant is saturated. Once you see fog, the impact rating is compromised; the glass must be replaced, not resealed.
• The opener strains, reverses, or the motor hums without movement. The door is out of balance due to spring failure, or the opener’s force settings haven’t been adjusted since installation. Running an unbalanced door burns out the opener gear in 6-12 months.

Replacement Cost & What’s Included

These are written prices, not estimates that shift on installation day. Haven Clause 1: the measured survey we leave with you and the final invoice are the same document. The range reflects what we find when we measure - a 16×7 door with a 150-mph wind-load rating and standard hardware sits at the low end; a custom 18×8 with 180-mph rating, decorative hardware, and TPE seal runs higher. Every replacement includes spring balance verification, opener force adjustment, and a documented photo record of the completed work. The 365-Day Done Right Promise covers labor and installation defects; OEM parts carry their own manufacturer warranty.

DIY or Call Us?

There’s a safe middle ground, and then there’s where DIY ends.

What you can check safely: whether the door is plugged into a working outlet, whether the opener’s manual release is engaged, and whether the photo-eye sensors are aligned and clean. You can also inspect the bottom seal for visible cracks and the cables for fraying - look for unwound wire strands like a frayed rope. Document what you see; it helps us bring the right parts.

What you should not attempt: torsion spring replacement, cable adjustment, or anything involving the winding cone. A standard 16×7 Mr-Glass door spring holds 100+ foot-pounds of torque. The winding bars can slip, the cone can fracture, and the resulting force can cause serious injury or worse. We’ve been called to Lauderdale Lakes jobs where a homeowner’s winding bar went through the garage wall. If the spring or cable is the problem, that’s a trained-technician job - background-checked, uniformed, with license number provided before arrival under Haven Clause 3.
