While finding your mirror cracked can be spooky, there are actually many logical and common reasons why this happens. First, the mirror may have been mounted unevenly in the first place. Over time, poor mounting leads to stress points that will eventually cause a mirror to crack. Other common causes of a mirror spontaneously cracking include dramatic temperature shifts, strong thunder or a loud crash somewhere in the distance, exposure to heat and sunlight, and an uneven wall in your home. It's also possible that your mirror had a manufacturing defect or microscopic cracks that occurred during glass cutting or handling that eventually caused it to shatter.

There is no blanket number when it comes to glass thickness for soundproofing. Thicker glass does help reduce noise, but it’s only part of the solution. Most single-pane windows use glass that’s ⅛” to ¼” thick. While increasing the thickness can cut down on sound, the real noise-blocking power comes from stacking layers. Double—and triple-pane windows are far more effective for soundproofing. The combination of mass and separation breaks up sound waves better than thick glass could on its own.

Yes, you can replace just one pane of glass in a sliding glass door, but you may need to contact the door manufacturer directly to get the proper dimensions of the pane. It’s also worth checking your door’s warranty, as various parts may be covered for a particular timeframe, so you may not have to pay for the replacement pane. But consider the condition of the rest of the door. If the door is old or in bad shape, replacing the entire door is probably more cost-effective.

For small cracks, glass-bonding glue that can be pressed into cracks may be able to save a broken mirror. If a corner of a mirror has been chipped, you may be able to conceal the fact by adding a border or frame to the mirror. Deeper cracks and chips should be addressed by a glass-restoration professional if you're trying to preserve an antique or heirloom mirror.
