Mr-Glass Impact Garage Doors Nationwide

Mr-Glass Impact Garage Doors: The San Diego Owner’s Guide

We stock and install Mr-Glass impact-rated garage doors throughout San Diego, with most complete door replacements running between $2,800 and $6,400 installed depending on size and finish. If your Mr-Glass door has a failed panel, bent track, or a spring that let go, we can usually match the part and have it on the truck within a few business days. Most San Diego homeowners discover the problem the hard way: the door sticks halfway up, groans when it moves, or a post-storm inspection reveals a panel crack that wasn’t there before the Santa Anas hit.

Key Takeaways:

• Mr-Glass impact doors are built for hurricane zones, but San Diego’s salt air and marine layer create different failure patterns than hurricane-coast humidity.
• We’re an independent San Diego service provider, not a Mr-Glass dealer, so we match parts by measurement and spec rather than part number alone.
• Every repair or replacement comes with a written price before work starts and a written guarantee on the labor.

Which Mr-Glass Models This Applies To

Mr-Glass impact garage doors fall into two main series: the MG-700 (single-layer steel with a reinforced impact skin) and the MG-900 (insulated double-layer with a heavier gauge frame). The quickest way to identify yours is to check the sticker on the inside of the top panel, usually on the left side near the track. If the sticker is gone, measure the panel thickness: the MG-700 runs just under 2 inches, while the MG-900 is closer to 2.25 inches with a visible foam core.

The compatibility gotcha we see most often in San Diego: homeowners replace a spring with a generic big-box spring rated for a standard steel door, not realizing the Mr-Glass impact door weighs 40 to 70 pounds more than a non-rated door of the same size. The spring fails again within six months, and the cycle repeats. We spec springs by door weight, not just door size, and we write down the rating on the invoice so you have it.

For panels and tracks, OEM Mr-Glass parts are available but can take two to three weeks to ship from the factory. In many cases, a quality aftermarket panel from CWS or a local fabricator matches the dimensions and impact rating at 60 to 70 percent of the OEM price. We’ll tell you which route makes sense for your door and give you prices for both before you commit to anything.

Signs Your Mr-Glass Impact Garage Doors Is Failing

• Door hesitates or reverses on the way down. The photo-eye sensors may be misaligned, but on impact-rated doors it’s often the reinforced bottom seal dragging on a warped track. The track takes a beating from San Diego’s temperature swings, especially in east county where summer days hit 100 and nights drop 30 degrees.
• Visible rust bleeding from the bottom panel corners. Salt air off the bay and the marine layer in neighborhoods like Point Loma and Ocean Beach accelerates corrosion on the panel’s weep holes. Once rust spreads into the impact skin, the panel’s rating is compromised and it needs replacement, not sanding.
• Grinding or popping sound when the door moves. This is usually a failing torsion spring losing tension unevenly. On a Mr-Glass door, the spring is under higher load than a standard residential spring because of the extra panel weight.
• Panel dent or crack that wasn’t caused by an obvious impact. The foam core in the MG-900 can degrade over time in direct sun, and the outer skin loses its backing. What starts as a small wave in the steel turns into a crack. We see this most often on west-facing doors in Clairemont and University City.
• Door sits crooked or leaves a gap at one corner when closed. This is usually a stretched cable or a failing bearing in the end bracket, not the panel itself. Caught early, it’s a $180 to $360 fix. Ignored, the panel twists and the track needs realignment too.

Replacement Cost & What’s Included

Installed Mr-Glass impact garage door prices in San Diego run as follows:

• Single panel replacement: $380 to $750 installed, depending on the panel position and whether it requires OEM matching for color and rating.
• Torsion spring pair (matched to impact-door weight): $280 to $460 installed, includes spring rating written on the invoice and a written labor guarantee.
• Track replacement (both sides): $420 to $800 installed, including brackets and fasteners.
• Complete Mr-Glass-compatible impact door, 16×7: $2,800 to $4,400 installed, basic wind-rated panel with standard hardware.
• Complete Mr-Glass-compatible impact door, 16×8 or custom: $3,600 to $6,400 installed, depending on insulation level and finish.

The price range is driven by a few things: whether we’re matching an OEM Mr-Glass panel or using a quality aftermarket equivalent, how much of the existing track and hardware is reusable, and whether the door opening needs new weather sealing or jamb repair. Every quote is a written price before work starts. If we find something unexpected mid-job, we stop and re-quote before touching it. You’ll never get a surprise change order from us.

All labor carries our written guarantee. If a repaired or replaced part fails within the guarantee period, the second visit is free.

DIY or Call Us?

Let’s be straight about the springs first: garage door torsion springs are dangerous. They hold enough tension to send a wrench through drywall or break a wrist if they release wrong. We don’t recommend touching them without training. Spencer Odell has seen enough DIY spring jobs gone sideways to say it plainly: this is a call-us part, not a weekend project.

What you can safely do: check the photo-eye sensors are aligned (the little green light stays solid when they’re lined up), clean the track with a dry rag, and look for obvious loose bolts on the brackets. If the door is heavy when you lift it manually with the opener disengaged, the spring is failing. That’s the point to call (619) 793-3248. We’ll tell you over the phone whether it’s likely a spring, cable, or track issue, and what the worst-case price looks like before anyone drives out.
