    Basement Waterproofing

    Nothing is more frustrating than dealing with a wet basement. It can damage walls and flooring and ruin irreplaceable things like photo albums and family heirlooms. But knowing the causes of wet basements and how to prevent water damage can help avoid this frustration.

    Foundation Repair

    Many basements have structural problems. The repair of these defects takes a professional to recognize and diagnose the multitudes of problems that can occur in basements. Foundation failures can include cracks, movement, leaning, bulging or bowing.

    Exterior Waterproofing

    An exterior drain system does not allow any moisture inside a basement or crawl space. As apposed to an interior drain system, an exterior waterproofing system diverts all water before it is able to come in contact with your foundation.

    Why Waterproof a Basement?

    The best way to maintain or increase your property value is to improve your home through repair, expansion, and remodeling. Basement waterproofing is one of the ways you can help keep your property value high while saving your foundation from potential disastrous situations brought on by rain. If water seeps into your basement, that is a bad sign. Basement leaks can mean your foundation is in need of repair to keep the walls from cracking or growing mold which can be deadly to your family.
    There are two ways to waterproof your basement, using either an Interior or Exterior Hydro-Static Pressure Relief System.

    Interior Waterproofing System

    An interior drain system is the cheaper route, but can still allow some water to come in.

    Thanks for your excellent work.  I know you are a man of your word and will finish the EZ Breath installation once the sheetrock is done. I did not see the need to hold the $100 as you suggested. I look forward to hearing from you soon about the estimate for re-finishing the sheetrock, and the estimate for laying down the vinyl flooring. Thanks again!

    Joe Soster and his crew installed a basement waterproofing system and a sump pump in my home. The quality of work was simply awesome; the crew respected our home, worked hard, and produced a great final product. The price was very reasonable. I am very satisfied!

    Thank you and your crew for working on the various parts of my house. You’ve helped me out in more ways than you could know, taking away much of the burden. I’m appreciative of the fact that you billed my only for the men’s time on the last day.
