Professional basement waterproofing company serving Baltimore, MD since 1987.

Same Ownership. Steve Taylor founded BWN in 1987 and continues in the day to day leadership role that he is famous for. This stability of ownership means you can be assured you will receive consistently great service.

Same Name. 34 years of continuous operation under the same name, the same corporation. It is a common industry practice for a Basement Waterproofing company to close, to go out of business and avoid performing warranty work but re-open the next day with a slightly different name. Folks whose basement waterproofed by BWN in 1987 have the same warranty as the folks hiring us today.

We are a professional basement waterproofer.
All we do is waterproofing.
