Resealing a 200-square-foot flagstone patio costs between $300 and $550. Cleaning supplies, such as vinegar, soap, and a scrub brush, add about $10 to $15 to your costs. Regular maintenance and cleaning preserve the stone's integrity and enhance your flagstone patio's appearance, keeping your outdoor living space inviting and long-lasting.

Cleaning a flagstone patio is difficult work. Start by hosing down the patio and then using a mixture of dish soap and water to scrub each stone with a bristle brush or large sponge. You might need to use white vinegar to remove mold. If the patio is too dirty, it might be worth the cost of hiring a professional cleaning service. If you need more than routine maintenance, budget between $3 and $30 per square foot for the cost of patio repair.

Flagstone for patios presents an inherently neutral natural color palette. You have many choices, including shades of grey, black, red, yellow, brown, and tan. Certain varieties, such as bluestone, produce a subtle bluish tint. The stone’s natural hues enhance curb appeal and provide a timeless elegance to your outdoor space.
