What is flagstone?

One important thing to note about “flagstone” is that it is not one specific type of stone, but rather the style or pattern of a particular installation. Stones which are most commonly cut into flagstones include slate, bluestone, quartzite, limestone, or sandstone. The flagstones themselves are generally between 3/8” and 1” in thickness and come in cleft and honed finishes. Interior flagstones may also be given a polished finish, but exterior ones typically are not. Flagstones as a whole are quite durable, but some stones are, of course harder than others. A comprehensive knowledge of the compositions and requirements of specific stone types is one of the advantages of having our expert technicians care for your flagstone surfaces.

Flagstone Cleaning

The majority of flagstone installations are outdoors, and as such they are exposed to all kinds of dirt, grime and contaminants, including things like moss and mold growth. We have the knowledge and experience to thoroughly clean and restore your flagstone surfaces to like-new or better condition.

We are always available to answer any questions and to discuss the specific requirements of your unique flagstone surfaces.

Sealing and Protecting Flagstone

For exterior installations, sealing your flagstone is not usually necessary except in certain circumstances. Interior flagstone, however can be sealed and even color-enhanced to make the natural colors of your flagstone emerge more vibrantly.
