Stone Masonry Sealing and Cleaning

Natural Stone:

Flagstone, limestone and bluestone are just a few of the many different types of natural stone or rock used in masonry construction. Most problems with natural stone occur not with the stone itself, but with the porous mortar that holds it together. Unsealed mortar will quickly absorb water from rain and snow. When this moisture freezes and expands, it can cause cracks to form and even cause the entire structure to break apart. A water-repellent sealer will stop the water from absorbing and will prevent this type of damage.

Manufactured, Cultured or Faux Stone:

This type of stone is really just colored concrete that has been cast in the shape of a stone. Manufactured stone accounts for over two thirds of our calls about "stone problems". These thin, porous stones are easily damaged and their thin layer of color is very vulnerable to effects of weathering and acid rain. Manufactured stone is so porous that water will absorb completely through the stone and into the wall behind it. Over time this moisture can cause all types of damage including mold, rot and decay. The constant presence of moisture also makes efflorescence a big problem too. Fortunately, cultured stone is also the easiest to protect with the right stone sealer.

We can provide cleaning, efflorescence removal and complete sealing services for all types of stone. Most stone sealing is done with a breathable penetrating sealer that seals and waterproofs while leaving a completely natural sheen and appearance. These products are easy to apply and work 100% below the surface to protect from within. They leave no film or coating on the surface and will never flake or peel.
