Note: Watch out for electrical cable and plumbing pipes.
Cut It Up With a Circular Saw
Sledgehammers, pry bars and reciprocating saws aren't the only demo heroes on the job site—your circular saw can be used for a heck of a lot more than cutting studs and sheets of plywood. Fitted with the right blade, your circular saw can cut up roofing, tin, concrete, rebar, steel doors and fiber cement. With a demo blade, you can cut up nail-embedded debris all day long.
Pull Drywall Screws
When you pull drywall from a wall, the screws usually stay in the studs. Unscrewing them with a drill is not the most efficient way to remove them because the screw heads are usually deteriorated or full of drywall mud. Use a pry bar or your hammer claw to pull them out just like you would with nails. Drywall screws are brittle, so if some joker used 3-in. screws to install the drywall, snap them off with your hammer.
