Basement Sump Pump Systems

If you get water in your basement every time it rains or you have an old sump pump that can’t keep up, a new basement sump pump can help keep your basement dry. Basement Systems has tested many pumps over the years and we use Zoeller pumps because we know they work.

Sump Pump Features:

  • Durable cast-iron pumps
  • Quiet operation
  • Battery-powered backup option for operation during power outages
  • Patented WaterWatch Alarm alerts of high water level

Basement Dehumidification

Moisture in the basement leads to mold growth that can damage your home, make you and your family sick, and make your basement and whole house smell musty. The solution is to remove moisture from the air. The SaniDry Sedona basement dehumidifier and air system from Basement Systems wrings the moisture from basement air and makes the damp feeling and musty smell go away!

SaniDry Sedona Features:

  • World’s most efficient dehumidifier without a bulky heat exchange
  • Automatic drainage - no buckets of water to empty
  • Automatic controls maintain ideal humidity level
