Hi there. The interior basement perimeter has an exposed gutter system that has no built-in drainage, and in order to refinish the floors I would like to know the next steps to getting a working plumbing system that would allow for the gutters to be fully covered by flooring without the potential for stagnant water and dampness occurring. I'd like to schedule a consultation. Thanks!

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

Foundation Repair

Foundation cracks and bowing walls aren’t just unsightly - they easily allow water to leak into the basement and they compromise the structural integrity of your home. Whether your basement is wet or not, we offer a full-range of home foundation solutions, including helical piers, basement wall anchors, and more.

Don’t let your foundation problems get worse - contact us today to schedule your on-site foundation inspection and free foundation repair cost estimate.
