Regardless of what's being demolished—concrete, houses, pools, garages, barns—there are usually many ways to perform demolition. The best way to figure out the demolition method that's best for your specific needs is by discussing it with an experienced and licensed demolition contractor. They will be able to meet you at the site and go over potential solutions. Because they're experts, they'll be able to go over your options with you in great detail.
It's good practice to always get proposals or estimates in writing. It should explain who is responsible for pulling and paying for permits, who is responsible for debris, and any other important information.
