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

Recent job requests for basement waterproofing in Boulder, CO:

Project Location: Boulder, CO 80303

Comment: I have a room off of my garage (under the front porch) that has some water penetrating into the space. I need it waterproofed (caulked and any of the other stuff you all do) from the inside of the room. Additional information: Needs help with: Waterproofing

Project Location: Boulder, CO 80303

Project Location: Boulder, CO 80304

Comment: Water getting into basement in corners & where walls meet floor

Project Location: Boulder, CO 80305

Comment: Install a sump pump to avoid underground water from entering the basement in the relatively wet season

Project Location: Boulder, CO 80305

Comment: Sump pump itself appears to be working fine, though it looks older than it is and covered in sediment, so maybe it should be cleaned/serviced. Check valve may need replacing, we hear water run down it after the pump runs for 10 seconds, but pump doesn't cycle too frequently so it must not be too much water that returns. There is a very strange gurgling sound though that continues for around 30 minutes after the pump runs though, which is mysterious. The pump discharge point is super jenky and freezes up when it gets cold out, looking for a solution for that. The sump pit does not have a sealed cover and we would like to add one that prevents radon gas from escaping while allowing it to still work as a floor drain. Finally, we don't have a tile drain system, and wondering if we should and what that would cost. The sump liner is old corrugated metal and maybe eventually needs replacing, want to understand what kind of an effort that is. Thanks!

Project Location: Boulder, CO 80303

Comment: We are buying a home that has a lower level door/landing that has a drain to a French Drain on the landing that is either plugged or just cannot handle downpour situations. Current owner has a sump pump on the landing over the drain to pump water to yard if drain backs up but we would like to put in a pit/pump such that water directly flows in the pit (to the side of the door) and gets pumped out to ensure no flooding could occur with water flowing into the lower level door/room

Project Location: Boulder, CO 80301

Comment: I have a current sump pump, but inspector said it was connected to city water and this is not allowed. I would like someone to look at it
