Basement waterproofing and foundation repair solutions to help you sleep through the storm.

Basement Waterproofing

Basement Waterproofing

Basements in Maryland and Delaware have wet walls and floors because they are prone to ground water leaks and seepage. In late summer, severe thunderstorms average once every five days making the region susceptible to flooding from several different sources. Keeping water out of basements is a real concern.

BWN is your number one source fore reliable, effective, and affordable basement waterproofing solutions. We are experts at determining the best methods and materials for any basement waterproofing need. BWN can permanently eliminate your wet basement problem for your home. With BWN, we make it easy for you!

Basement Waterproofing
Foundation Repair

Foundation Repair

Foundations for buildings are often built using concrete blocks, solid poured concrete, field stone or red bricks. Modular basement foundation designs are also available for new construction. Below ground foundations can constructed as shallow crawlspaces, half basements, or full basements.

Concrete, over time, can develop hairline wall cracks that have the tendency to progress into larger wall cracks and foundation fractures. Concrete floors can sag and pull away from the bottom of basement walls.

These foundation movements are a clear sign your foundation is in need of structural repair.

Contact BWN today to get your foundation fixed right for life.

Crawl Space Repair

Crawl Space Repair

Most crawl spaces in Maryland and Delaware have limited functional space and tend to be dismissed as less important than basements. However, crawl space problems have far reaching effects that can invade the living spaces above. The more common issues are water seepage through the walls and floor, high levels of humidity, musty damp odors, and mold. The good news is these problems can be permanently corrected.

A crawl space that has been properly encapsulated and waterproofed can provide space for storage and more importantly contribute to a dry, healthy environment that protects the living spaces above. Dehumidifiers with filters that are specifically designed for crawl spaces are game changers that restore lower level spaces that were once uninhabitable into fresh, clean functional areas. With BWN, we make it easy for you to transform your crawl space.

Sump Pump Services

Sump Pump Services

If you live in Maryland or Delaware and you have a basement, you most likely have a sump pump. If you don’t, you most likely should as sump pumps are required in all new home basements.

Reliable and properly installed sump pumps can be life savers when dealing with groundwater leaks, heavy rainstorms, and flooding.

Contact us today if your sump pump isn’t working properly, is more than 5 years old or needs maintenance in Maryland and Delaware.
