Why clean and treat your deck and/or fence?

When a deck or fence is several years old, elements such as sunshine, rain, and snow take their toll on the surface. Cleaning and treating is critical in extending the quality and life of your deck/fence. Staining, also referred to as resealing, is a way to insure your deck/fence remains healthy, long-lasting, and looking great for years to come.

Why wash and seal your concrete surface?

Over time dirt, mold, and mildew work their way into concrete surfaces. Simply hosing off concrete will end with poor results. With the right pressure wash and sealant applied by our specialists your concrete surface can look brand new.
