Baltimore, MD Sump Pump Service

A sump pump works to remove water that has accumulated in a sump pit. A sump pit, typically located in a home’s basement, is simply a hole/pit to collect water. The water may enter via the perimeter drains of a basement water management system, or from flooding by heavy rain or because of natural ground water if the basement is below the water table level. Pump HP is based on what the performance need is.

Basement Waterproofing Technologies has the experience and knowledge to assess, upgrade, and replace your sump pump to prevent water damage and basement flooding. We also recommend installing backup sump pumps.
