    Dan H. of Baltimore, MD

    Customer Testimonial

              When Dan H. purchased his Baltimore, MD home, he had great plans to tuns the large basement with great, large windows into a finished space for his family to enjoy. They soon found out that the basement finishing project would have to be postponed because there was a water intrusion problem that would eventually lead to even more problems if not fixed. As a savvy homeowner, he really did his homework when it comes to selecting a company for the job, from getting recommendation from a trusted neighbor, to checking the company's reviews pasted in trusted online sources. That is how he found Basement Systems USA, and after getting to know the products and solutions we offer, he was 100% confident that this was the company for the job. In this video he talks about the experience he had with the company and the results after installation. "I am really happy with the investment that I made.", says Dan.

Affordable, Certified Waterproofers for greater Baltimore, Philadelphia, West Chester, and Lancaster

Basement water problems are as old as the structures themselves. Water will leak into a basement through any opening it can, including your walls, floors, and the joints between them. Water can even pass through the concrete itself -- which is one reason why basements are notoriously damp, humid spaces.

Other companies might try to sell you on inferior basement waterproofing solutions. Our products have been developed, patented, and perfected by Basement Systems®, Inc. -- the world's largest network of basement waterproofing contractors.

Whether you live in Philadelphia, Wilmington, West Chester, Newark, Baltimore, Lancaster or Parkville, our basement experts will show you how we can customize your waterproofing solution to keep the basement dry all the time!

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
