Nothing is more frustrating than dealing with a wet Haverford, PA basement. Knowing the causes of wet basements and how to prevent water damage can help avoid this frustration.
There are basically two ways to waterproof a Haverford, PA house or building. The first and most common way is from the inside using a French Drain…
An exterior drain system does not allow any moisture inside a Haverford, PA basement or crawl space. This system diverts all water before it is able to come in contact with your foundation.
When water finds its way into the basement of a structure, the owner needs to remove it because it could lead to mold infestation and weaken the basement foundation walls.
If excessive water often accumulates around your home’s foundation and lawn, you may be in need of a lawn drainage system. Our pros specialize in lawn drainage and grading.
We diagnose a multitude of problems that can occur in basements, including cracks, movement, leaning, bulging or bowing.

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.
