Natural stone is a beautiful and long-lasting substance, hence it is rather expensive. Stone patios typically cost between $15 and $30 per square foot, not including installation. Wood or concrete is much less expensive at about $5 to $10 per square foot. The price of natural stone depends on the type of rock used for the patio. If you go with a cheaper type of stone, such as sandstone or limestone, your patio will likely need to be resealed every few years because they are porous materials that can eventually become cracked if exposed to too much moisture. The other major factor in pricing is the size of the rock used for the project. Larger pieces of stone are pricier than smaller ones. Also, more expensive types of stone such as granite require special care. It's recommended to have your stone inspected by a professional annually to ensure it's safe. Overall, natural stone is an elegant and affordable option for your outdoor living space. The price will vary depending on the type of rock you choose and its size. However, even the largest and most expensive patios don't last forever, so consider how you want your patio to look after five years or more. If you plan to spend lots of time out there, then take the time now to find a stone that fits with your lifestyle and budget.
