    Tom B. of Forth Washington, PA

    Customer Testimonial

              For 36 years, Tom B. and his family lived with a wet basement that would get 6 to 10 inches of water every time their power went off during a storm. He knew that they would have to fix the problem if they were to stay in the house. A trusted friend recommended Basement Systems USA to Tom. In this video he talks about the entire experience provided by the company, from the sales process, to installation and results. "They were absolutely fantastic! At the end of five days we were convinced we got the A Team.", says Tom.

    Customer Testimonial

              I called and spoke to a real person-wow! Was well prepared for what seemed like a great start. So, now we would hear from a sales person. I received a call that afternoon from some guy named Jeff. Well, Jeff was very polite and asked if we wanted him to come out. Yes it was, and low and behold it was going to be our choice when and where. We said the next few days and Jeff says what day was free and then asked what time would be good for us Our day, our time and here comes Jeff – right on time, so here we go. Jeff knew the inside and outside of this business, he had been putting these in for a good many years- We took the tour, and sat down with some brochures of the product that they use and how and what they could do. He gave us what seemed like good info but we wanted to think about it, so we did not commit and told him we would call. We put it off for awhile and Jeff e-mailed me only once to make sure we knew he was still around. Never bothered us as we asked him not to call-we would call him. Got him back and went over our house again and went with most of his idea's. Not pushy at all. Here we go- Here comes a person named Sean to our front door. He told us who and where he was from and what his job was. We went down the stairs and looked over his work assignment, an I got he hek out of there. My wife and I moved and covered some of the basement "things". I went down when I heard the jack hammers, and when I got down the crew had everything else covered up. Sean was answering all my questions and telling me how and when they would be done. Well it turns out that Sean had something to add, good idea that installing a new drain would be better than using our old drain- seems all the downspouts were draining in the old pipe. They added that to the workload. Quite a good salesman. Next Sean said he and his crew were starting the walls. Sean asked what the future of the walls would be - lo and behold we were putting on wall covering that would have to be removed for our future projects. So, we decided to do it right the first time and change the plan. My first choice was the ThermaDry system, so after hearing what was going to be done, Sean said there was a nicer finished wall and it was called ZenWall, I looked at the ZenWall and said it was real nice so he got a price for the new product and that's what we got. It looks great. I just can't say enough about this crew. I would definitely recommend them to anyone! So now the word is out about Basement Systems USA

              Gary arrived exactly on time. He is wonderful individual. I didn't feel any pressure with what was described to me for my basement. We discussed all of my option. I was happy with my decision during and after I signed the proper papers. My install was scheduled that very day and in less than 2 weeks I have a new basement. My sump pump was installed without too much interruption to my family life. My basement looks amazing. The waterproofing material and chair rail looks great. It hadn't rained much since the installation, but I am confident that there will be no more problems in my basement with leaking.

    Sandra R. of Baltimore, MD

    Customer Testimonial

              Basement Systems USA recently installed a Super Sump system and waterguard track in my basement and an outside underground sump pump drain pipe with ice guard and lawnscape outlet. The crew did an excellent job installing everything and cleaning the work area when finished. My only criticism was that, after installing the new discharge pipe, they didn;t cement over the hole they'd made in the concrete wall. I called the service dept and the manager said of course they'd fix that. I also asked if the outside drain pipe could be shortneed so the lawnscape outlet would drain better over the lawn. Again, he said yes because they wanted me to be satisfied. Mike Dyer was the technician who came to do the additional work, and I can't praise him enough. He d id a beautiful job of cementing over the hole in the basement wall-- you'd never know it was there. He shortened the outside drain pipe, refilled & tamped down the trench, and then went the extra step of obtaining & installing a popup outlet that works better in my yard. Mike also installed an 8' chute on the downspout to drain water away from my patio. Basement Systems did not charge me for any additional work. They mean it when they say they want their customers to be happy. I would recomment them without hesitation.

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, Baltimore, Ellicott City, Wilmington, Upper Darby, Parkville or Lancaster, 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.
