BBB accredited business



We solve wet basement problems and repair foundations permanently.
Our first goal is helping you to understand why your basement leaks.  If you understand why it leaks you will be in a much better position to make a good decision on what you need to do to correct it.  We are not a sales organization we are Waterproofers.  We fix wet basements one at a time with time-tested methods and excellent materials as opposed to selling the latest "Patented" product.
