Cut Off Top Half of Cracked Bathroom Mirror?

Apr 25, 2017 5 Replies

Mirror is about five feet wide x four feet tall. Crack is in the top half, about two feet long, terminating at an edge. What are the chances a professional can cut the top half of the mirror off, leaving the bottom intact?



Caution to others: I cracked the mirror when I was re-installing a light fixture. A drywall screw passes through the mirror and into a stud. I must have overtightened. A few hours later, the crack appeared.


Trivial thing if you can take the mirror down.

'Bout 100% -- if don't want to try to cut too close to the break; very small cutoffs are difficult to near impossible to get clean edge.

But, of course, you're wanting to save all the unbroken piece. :)

My pleasure, Oren, Ed, and CRNG.

A bit more: The original mirror had roughly 4 feet x 2-inch trim pieces, on e on each vertical side of the mirror, attached with double-sided tape. The trim's long edges are beautifully beveled. Today I marked the new length o f the trim that I wanted with a sharpie marker; put on safety glasses, thic k gloves, and a breathing mask; and etched the trim using a 3/4-inch diamet er diamond rotary cutting disc. The disc was mounted on my ordinary Black a nd Decker electric hand drill using the mandrel that came with the discs. I bought these little discs at Harbor Freight some years ago for a metal pro ject. See

I put the trim on the sharp edge of a work table, tapped on the back a litt le with an ordinary hammer, flipped the trim, and easily snapped it to the marked length. I sanded the cuts a bit with 100-grit sandpaper. After some practice with scraps, the last cut I did is so good it is hard to tell the difference between it and the professionally done ends.

Good job, I didn't think it could be done, I know I would not have been successful. Thanks for the follow up.
