Have you ever noticed white powdery material on the outside of your chimney? This is caused by water penetrating the brick. The white powder is lime and salts in the mortar being pushed out by pressure and water vapor evaporation out of the chimney. We have found the best products to help prevent this problem. Chimney Saver®, a water repellent treatment.
This material is far superior to similar items you find at Lowes or Home Depot. Most products you buy in the local home store’s are sealers, (ie. Thompson Water Sealer) this is not what you want to put on brick chimneys. Water vapor must be able to pass through the brick for the structure to dry. Some treatments can actually cause more damage to your chimney, however Chimney Saver® is specifically suited for masonry chimneys. It creates a bond to the brick and helps prevent water from entering the pores of the brick by creating an invisible shield of the surface while allowing water vapor to escape through the bricks pores. We have been very happy with results from using this fine product.
Water repellent treatments have to be quoted on an individual basis. We will be happy to come by and look at your chimney, just give us a call.
