Can anyone advise on how to safely remove a large mirror without damaging the wall?

Hey there! So, I recently purchased this house and I’ve been thinking about taking down this mirror. I’m not too worried about keeping it in one piece, but I definitely don’t want to cause any damage to the wall. Does anyone happen to know if these mirrors are usually made up of separate panels or if it’s just one big piece? Any tips or tricks for removing it safely? I’ve heard about using tape and shims to help it come off gently. Any advice would be much appreciated!
Typically comes off in one large piece.
Make sure to tape it up. Additionally, consider taping plastic over the front to prevent glass shards from scattering in case it shatters.
I also invested in a pair of suction cup shower handles. They are incredibly useful for putting up/taking down mirrors as they provide a secure grip on an awkward object

There’s a high chance that it’s a two-way mirror with a camera on the other side, so removing it shouldn’t be too difficult. 🤣 🤣
Tape up the area and carefully remove the mirror from the wall. In order to avoid breaking it, it’s advisable to prepare properly. If you can access the back of the mirror, try using a scraper or metal wire to cut through the adhesive.
The central part is a single piece, with 3 separate pieces on each side at the bevels… unless my eyes are deceiving me
I’m really looking forward to that!
I’ve tried this a few times before.
I highly suggest adding a horizontal strip of 1×2 to the wall underneath it, end to end, as a safety measure; positioned about 1/4-1/2” below it, and insert a rag or foam between the wood and mirror so if it starts to come off the wall, it won’t just fall and potentially break. Secure it into at least 2 studs.
You could also use plywood or any material you can prop up under it and hold in place.
You should also tape it, but also onto the wall to prevent it from just tipping over the edge onto the floor. The tape will help cushion the fall.
If you could create the horizontal strip with two pieces including another strip of wood, that would be even more secure. Good luck!
I appreciate it! That information is extremely useful!
Yeah, we definitely need something underneath to support it. It’s great to have a helper around too.
Seems to consist of 7 pieces. Mine were affixed with black adhesive. That adhesive was stubborn and required careful removal to avoid damaging the wall. After that, I had to smooth out all the imperfections with patching compound. Finally, sand, prime, and paint.
You have the option to utilize a cable saw of some kind, or even create your own and simply move it back and forth behind the mirror… https://www.instructables.com/How-to-make-a-cheap-wire-saw/
That’s my usual way of doing things.
I once had wooden panels glued to my walls. Be prepared to do some patching and skim coating on the entire wall after removal. In the worst-case scenario, you might have to replace the drywall entirely or add new 1/4” drywall over it.
I skimmed through the other comments, but we successfully took out a large mirror with wire and minimal damage to the wall!
If the mirror is glued to the wall, the simplest and safest method would be to tape the entire mirror, cut around it with a utility knife, and then remove the drywall along with the mirror. You’ll likely have to do some drywall repairs regardless. Another option is to cover it with a heavy tarp, break it with a hammer, and let the pieces fall onto a tarp before disposing of them.
If you’re fortunate, it depends a lot on the age. Many of these are attached with double sided tape. In that case, it will come off with heavy duty fishing line. If it’s mirror adhesive (black in color), or in the worst case, construction adhesive (usually tan and fragile). Protect your hands with gloves and wear safety glasses. I suggest starting with a wide blade putty knife, like a drywall knife. Begin by probing behind the initial panel. Run the knife around the edges to check for any movement. If possible, place shims behind the mirror to help loosen it. Be cautious and prioritize safety.
: The house was constructed in 2000, so who knows what we might discover. It’s going to be quite an adventure!
Yes, as a last resort, breaking out the drywall should be avoided. Grab a putty knife and shims for about 20 dollars, heavy-duty fishing line for 15 dollars. The cost isn’t really in the drywall sheet itself, but rather the mess and chaos it can create in your home. 1/8″ beveled glass might not seem too daunting until you end up in the ER. Trust me, just proceed slowly and with extra caution. Even if you damage the wall, putting it back together isn’t too complicated.
Is thankful for the additional words of caution.
Hey there, the six stitches in my arm, not great, but luckily the scar is barely visible.
I’ve heard some people suggest using wire. Personally, I prefer using a heat gun along with an air bag. By heating up the glass, you can soften the glue and then carefully slide the air bag behind the mirror while gently pumping it.
As Victoria recommends, use suction cup handles. Start from one end and move across pulling it off the adhesive. The adhesive is often only in a few spots. I covered the whole thing with adhesive contact paper.
Seems like you’re in a vacant room. Lay down an old quilt on the floor and hang another one on the wall above the mirror. Tap gently with a hammer.
If the mirror is still in good condition, it could be worth something. You might be able to find a nearby glass/mirror shop that will remove it for free just to get the mirror panels. The beveled edges may cost extra.
Let me give a couple calls and check. Sounds good, right?
