Granite is a durable natural stone known for its strength and resilience. When properly cared for, granite countertops can last for decades, making them a wise investment for any home. The longevity of granite countertops is due to the stone's natural hardness and resistance to scratches, chips, and heat. With proper maintenance and care, including regular cleaning and sealing, granite countertops can maintain their beauty and functionality for many years. The exact lifespan of granite countertops will depend on various factors, including the quality of the granite, the installation process, and the level of care and maintenance they receive. However, with the right care, it's common for granite countertops to last 30 years or more.
