Caring for Flagstone Patios

Flagstone Patio Cleaning - Waterproofing - Stone RepairDuring the hot summer months, a patio is the perfect place to grill up a meal, gather with friends and family, or just relax with a cold drink. But what many people don’t realize is the care that needs to be taken to keep your flagstone patio in good condition. In this post, we’ll go through some of the most important types of maintenance to ensure that your flagstone patio is in tip-top shape.


Flagstone, like many other types of natural stone, is subject to water damage if not properly sealed. This is especially important in areas where the water is alkaline, or contains traces of minerals which may add to the erosion of the stone.

To prevent this type of damage, it is important that your flagstone patio be sealed/waterproofed with a sealant made specifically for natural stone. If your patio is already starting to show signs of deterioration, the damaged pieces should be removed or replaced before applying a sealant. Trained masonry contractors can repair this type of damage, and properly apply the coating so your patio stays damage-free.


Experts recommend thoroughly cleaning your flagstone patio twice per year, though many property owners opt for only a yearly spring masonry cleaning. To clean a flagstone patio, it is important to have a cleaner designed to work on natural flagstone, and that the cleaning solution covers every facet of the stone and mortar. The cleaner should then be rinsed with a pressure washer to ensure an attractive appearance.


Unfortunately, even with the utmost care taken, normal wear and tear can degrade the appearance and function of flagstone patios and walkways. Seasonal changes in the weather can cause the stone work to repeatedly freeze and thaw, causing damage to the flagstone and mortar. In cases like these, the patio may need to be re-grouted. A skilled mason will grind down the existing mortar connecting the flagstones, and replace it with fresh new joints, restoring beauty and stability to your patio.

A flagstone patio or walkway is one of the most beautiful additions you can make to the landscape of your home. Plus, with the proper care, it can last a lifetime. With the correct waterproofing, regular cleaning, and competent crack repairs, your flagstone patio will keep serving you for many summers to come.
