How to Remove a Countertop Safely

Clear Off the Countertop

Before you begin your countertop removal, you’ll need a clear surface. Relocate any dishes, cutting boards, appliances, or anything else on the counter’s surface to another area. Once you’ve cleared your countertops, remove the drawers and items in the cabinets underneath your counters. That’ll prevent dust and debris from getting into your stuff, making clean-up easier.

Disconnect Supply Lines

You’ll need to shut off the three main utility sources before you begin your countertop removal:

• Turn off the main electrical power supply to your outlets (usually at the fuse box).

• Shut off the gas line (use your wrench or the valve knob, if needed).

• Take your bucket and place it underneath the sink to catch any stray water, then turn off the supply line valves, disconnect your water lines, garbage disposal, and drain lines.

Remove Sink

Be sure you have someone else nearby to help you with this step—sinks can be heavier than you might imagine—especially if you have a sink made of a heavier material such as cast iron. There are two basic types of sinks: drop-in and undermount.

• Drop-ink sink: Use your putty knife to slip under the rim and chip away at the adhesive holding the sink in place. You may need to use the caulk softener to remove the adhesive, so keep that handy. Once you’ve detached the adhesive, you can lift the sink out.

• Undermount sink: Unscrew and remove the brackets under the counter that hold it in place. Undermount sinks also use caulk to seal them into place, so use your putty knife and caulk softener to remove this sealant. Once you’ve unsealed the sink, lift it out.

“For demolition, your reciprocating saw is your best friend,” says Bob Tschudi, Expert Review Board Member and Raleigh, N.C.-based general contractor. “Be sure to have all-purpose blades as well as metal-cutting blades. For cabinet removal, we often have to cut the screws that secure the cabinets to the walls.”

Loosen the Adhesive

Now you’re ready to start removing the countertops. Countertops are usually sealed onto the base with adhesive. Using your caulk softener, spray around the edges of the counter and backsplash, then let the softener sit for one hour.

Separate Counters From Backsplash or Wall

After the hour is up, use your putty knife or box cutter to pry the counter away from the wall or backsplash, as well as the base. Move carefully around the edges of your countertop, loosening as you go until it is loose enough to lift a bit. You may have to use a hammer with your putty knife to wedge between the backsplash and the wall—the adhesive softener should help with this. If you need to use a hammer, be careful not to damage your walls as you separate the countertop.

Unscrew Countertops

In addition to being held in place with adhesive, your countertops might also be screwed in underneath. You’ll likely have to get in the cabinet and look up to see where the screws are. Once you’ve located them, use a screwdriver or a drill with a screwdriver bit to remove the screws.

Remove Your Countertops

After removing the screws, you should be able to lift your countertops off of the base cabinets. This is another step where a second person will come in handy since countertops come off in larger pieces and can be heavy and unwieldy. If you’re replacing your countertops with laminate or a solid surface, you can leave the plywood sub-surface in place. Otherwise, you can remove this as well by lifting it off.

Dispose of Your Countertops

Many municipalities won’t take construction materials with regular trash, so you’ll need to make special arrangements for your old countertops. You can rent a dumpster if you’re doing a larger renovation project, or in some cases, you can make special arrangements with the city to pick up bulkier items.
