“Very communicative in explaining what was being done each day & then walking us through the work at the end of the day. The team worked extremely hard - having a long carry for all materials & cleanup. The completed work looks good. Work completed on schedule.” - Lynne Damon
“Team Tom and Frank did an AMAZING job at our home in Rosedale MD installing an egress window. Very professional team, organization job site, always kept us informed of progress. Highly recommend BWN for any basement leakage.” - Mary Beth Lukas
“The team was efficient, professional, courteous and did a great job on the basement. They took care to protect the floors and keep the dust down during the work. They kept me informed at each stage and completed the work in the expected time frame. They even made friends with my cat and made sure he stayed inside. I am very pleased with the work and the company.” - Julie Fletcher
Common Basement Leak Problems and Solutions
Basements in the Baltimore MD area are designed and built as masonry structures that extend below ground. After a heavy rain, the soil that surrounds the basement saturates with rainwater. This water will often find ways to enter through the exterior basement walls and into the home’s interior environment.
Water seepage has consequences that reach far beyond the basement. Ignored, this exterior moisture will quickly and easily find its way into the home’s interior living spaces.
Common wet basement problems include everything from basic basement water leakage to water damage on basement walls and floors. Wet basement solutions range from simple repairs to exterior and interior basement waterproofing systems.
