Choosing the right Flagstone
When it comes to outdoor masonry projects, it’s hard to go wrong with flagstone.
Flagstone is easily recognizable because of its irregular surface, natural lines, and subtle but clear color variations. It’s a versatile stone that stands up to years of use and requires little maintenance if properly installed.
Cut Type
The first thing to determine is whether you want flagstone that is cut or split. A cut stone has clean, sharp edges. Cut flagstone creates a sophisticated look that will work in the most elegant layouts. Split stone has rougher edges, giving it a more natural look that’s suitable for rustic or casual styles.
Check for Quality
Thickness. Flagstone that’s too thin won’t hold up to constant traffic or the wet outdoor conditions that our area experiences. Most masonry experts recommend choosing flagstone that is at least 1 1/2 inches thick.
Surface pitting. Look for stones that have a solid-looking surface. Porous stones are a good choice in dry climates because they absorb moisture and stay cool even when under a hot sun. But they won’t do well in wet weather, where those same qualities will make them crack.
Hardness. You might think that when it comes to stone, the harder the better. But the stone that’s tough is also tough to work with. It will require specialized masonry expertise and annual maintenance.
Installation. Proper installation is a key part of ensuring your flagstone looks good for many years. When you discuss the installation with your mason, ask about the pros and cons of using a sealant on your flagstone.
Choose Your Color
Flagstone is formed out of local elements and every type will reflect the colors of those elements. For the most natural-looking hardscape, use flagstone in the colors that naturally form in your region. Usually, that’s the type of flagstone that’s also best suited for the weather in that region.
Flagstone Types and Colors
Limestone. A pale stone that comes mainly from the Western plains, limestone has shadings of pale gray and tinted cream. It’s a heavy, durable stone that will stand up to most applications.
Quartzite. This stone from the mountain West is notable for the mica in it, which gives it a sparkling look. It tends to be dark charcoal in color. Quartzite is an exceptionally hard stone that can take a lot of abuse.
Bluestone. There are two types of bluestone. Pennsylvania Bluestone is from Pennsylvania and New York. It comes in various shades of deep blue, purple and lilac. Shenandoah bluestone comes from the Shenandoah Valley in Virginia and is uniformly bluish-gray in color. Wherever it comes from, bluestone is a tough, long-lasting stone that is an excellent choice for any outdoor area.
Sandstone. This stone from Arizona and other parts of the southwest is a great choice for hot, dry climates. It comes in reddish and pink-toned shades. Sandstone is not a good choice for outdoor installations in cold, wet weather.
Travertine. This stone stands out for its light, bright colors and swirled patterns. Travertine is formed in natural geysers, which gives it a distinctive yellow, gold and red coloring. Travertine is a good choice for an indoor installation like an enclosed porch.
Slate. Slate is native to the northeastern U.S. and has a high clay content. Slate comes in a wide range of colors from blue-gray to rich red, with many stones showing two or more colors. Slate is easy to work with, making it a great choice for wall claddings as well as walkways.
