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

Project Location: Belden Hill Rd, Norwalk, 06850

Comment: Waterproof seepage and dampness in lower level.

Project Location: Arnold Lane, Norwalk, 06853

Comment: We are in the process of purchasing a home that has shown seepage in the basement. It also tested for elevated levels of radon (around 4.6). We would like a quote for a basement system that would guarantee dryness as we ultimately would like to finish the basement in the future. Additionally, do you offer radon mitigation systems? Thanks in advance!

Project Location: Cricket Lane, Norwalk, 06850

Comment: Getting water in (unfinished) basement during heavy rains.

Project Location: Ledgewood Drive, Norwalk, 06850

Comment: When we get very heavy, consistent rain, I get some water that leaks in from the perimeter of my basement. I've lived in my home now for three years and it has happened at least twice every year since I've lived here. My basement does not fully flood and most times, the entire basement floor is not covered. The water shows up in random spots or puddles generally along the perimeter, but also in the center of my basement floor. My walls are completely fine and I'm also wondering if I put in an indoor drainage system, how will the water that randomly forms puddles in the middle of the basement, travel to the drainage system that would be installed on the perimeter of my basement?
