When to remove the mirror glued to the wall

There are two reasons to remove a mirror glued to a wall: to bring it up to date or to repair a damaged mirror. Frameless mirrors stuck to a wall can look dated and less refined. Swapping out your dated mirror is an inexpensive way to update your bathroom instantly. If you’re ready for a new look, gather your tools and remove that old glued-on mirror.

Security Considerations

Since you will be working with a large piece of glass, safety issues should be considered before you begin. Breaking the glass to remove it is not recommended, but you should be prepared to break it. Dress in long sleeves, long pants, and closed shoes, and wear thick work gloves and eye protection at all times while working. Bringing in a partner is a good idea if you’re pulling out a large mirror.


• Heavy canvas drop cloth
• Heat gun or hair dryer
• Drywall/putty knife
• Protective glasses
• Thick work gloves (preferably leather)
• Wire saw


• Duct tape or packing tape


1. Protect yourself and the area

Before starting the demolition, make sure that all obstacles are removed. If your mirror is above a vanity, remove all clutter from the counter. Put on your safety gear then cover the floor or counter with a heavy canvas drop cloth.

2. Paste the mirror

Cover the mirror with strips of tape, crossing them in several directions. You can cover the entire mirror or place strips of tape every few inches. The adhesive tape prevents shards of the mirror from flying all over the place if it breaks.

3. Heat the glue

This method works best for small mirrors (2×2 feet or less). Apply heat to the corners and edges of the mirror with a heat gun or hair dryer, then work toward the center. Hold it 6 to 12 inches away from the mirror surface. Leave it pointed at the mirror for at least 15 minutes to melt the adhesive on the back of the mirror.

4. Raise a corner

Slide a putty knife or the blade of a drywall knife between the mirror and the drywall in the bottom corner. Place one hand under the mirror. Once the blade is in place between the wall and the mirror, pull the handle slightly towards you to unstick the mirror from the wall. When the mirror comes off, use your other hand to hold it and pull it away from the wall. Don’t worry if a drywall comes off with the mirror.

5. Inspect and repair

Once the mirror is removed, inspect the wall for any lingering adhesive. If there is, use the heat gun to soften it, then scrape it off with the putty knife. Repair and paint the drywall as needed.

6. Drag the wire

Take the wire saw and hold it by the handles. Starting at a top corner of the mirror, place the wire against the wall and slide it between the mirror and the drywall. You may need to slide the wire back and forth slightly to start it and run it through the corner.

7. Keep sawing

Make sure the wire is snug between the wall and the mirror. Quickly move your handles back and forth while pulling the wire down. As you’ve seen, the friction has broken through the adhesive, allowing you to pull the thread down as you go. Saw about ¾ of the way and stop. This helps prevent the mirror from falling or breaking.

8. Remove the mirror

With the help of a partner, lift the mirror from the wall. Go slowly to minimize damage to the drywall. You may need to use the wire saw or heat gun to melt the remaining adhesive if it is stubborn. Once you’ve removed the mirror, remove any remaining glue on the wall by first softening it with a heat gun, then scraping it off with a putty knife. Repair and paint the drywall as needed.

When to call a pro

Although removing a glued-on mirror is a straightforward project, there may be an opportunity to seek professional help. If your mirror is particularly large or in a hard-to-reach area, a general contractor can help you remove it safely. Also, if the adhesive is extremely firm and you can’t cut or melt it, a professional has the proper tools and experience to do it quickly and safely.
