Before we talk about our flagstone cleaning and sealing processes, it’s helpful to understand the unique challenges presented by flagstone.

Flagstone is almost always a Sandstone. Flagstone refers to the cuts and the installation with large irregular shaped pieces of stone and large grout lines.

Any stones can be cut and installed as a Flagstone pattern. Sandstone is a sedimentary stone that is deposited as mountains are turned into sand grains by erosion. After a time, the sand grains are compacted together and bonded together by minerals to form a solid rock.

There are several different types of Sandstone depending on where it is mined from the earth. All Sandstone is extremely porous and susceptible to staining, water erosion, mineral deposits on the surface, and efflorescence from within the stone. Sandstone is not susceptible to etching. The most common uses for Sandstone installed in the Flagstone pattern: Exterior deck covering, interior floor covering, and swimming pool deck surrounds.


We are the Flagstone cleaning experts. We understand the complexities of sandstone and the Flagstone pattern. Because the grout lines are thicker than those of other types of natural stone, it’s important to hire our experts to come clean and seal your patio or interior flooring.

The cleaning process for interior flagstone is the same as for exterior flagstone, but the sealing process for the two is usually very different. We use topcoat sealer indoors and a penetrating sealer combined with our stone densifier outdoors for protection from the elements. See the links below for more information about the differences between our interior and exterior flagstone cleaning and sealing services.
