Preparation: What to Do Before Removing a Marble Slab
Step 1: Identify Marble Slab Attachment Method
Most marble slabs are attached with:
- Construction adhesive
- Mortar/cement (especially on older fireplaces)
- Screws or brackets (behind trim or frame)
Knowing the method helps determine how much force is safe to apply.
Step 2: Protect Surrounding Areas
- Lay down a drop cloth to protect flooring.
- Tape edges of the fireplace with painter’s tape.
- If you’re removing a mantel, take that off first.

Step-by-Step: How to Remove Marble Slab from Fireplace
Step 1: Loosen Caulk and Sealant
- Run a utility knife along all visible seams, joints, and caulk lines.
- This includes the perimeter where the slab meets drywall, wood trim, or other slabs.
- If silicone caulk is present, gently scrape it off using a plastic putty knife.
Step 2: Gently Pry Around the Edges
- Insert a putty knife behind the slab and wiggle it slightly to test how tight the adhesive is.
- Tap a rubber mallet on the putty knife to slowly deepen the separation.
- Upgrade to a flat pry bar for stronger leverage.
⚠️ Avoid using metal tools on the marble surface to prevent scratches.
Step 3: Use a Heat Gun (Optional)
If the slab is stuck with adhesive:
- Use a heat gun on low to medium setting to warm the area behind the slab.
- Heat softens the adhesive and allows easier prying.
This step is optional but helpful for polished marble slabs or installations with strong bonding.
Step 4: Remove the Slab Carefully
- Once loosened, lift the slab vertically, not horizontally.
- Have one or two assistants help support the slab’s weight and balance.
- Place removed slabs on a padded surface to prevent cracking.
For larger fireplace panels or hearth slabs, you may need lifting straps or a marble slab dolly.

- Use acetone or mineral spirits on stubborn spots, but test first.
- If you plan to reinstall the slab elsewhere, polish and reseal it before installation.

Important Safety Tips
- Always wear gloves—broken marble edges can be sharp.
- Don’t use power tools directly on the marble.
- Lift with your legs and keep slabs upright during movement.
- If mortar or cement was used, be prepared for chipping and adjust expectations accordingly.
