All Basement Systems dealers have one common goal: to provide customers with the most effective and proven methods to waterproof basements and keep them dry all the time!

About the Founder

Founder Larry

The story of Basement Systems starts with company founder Larry Janesky. In 1983, Larry put an advertisement in the local newspaper saying: "Carpentry. No job too small. Call Larry."

He started getting calls. Eventually, he started his own homebuilding and remodeling company. Soon after, Larry saw the need for basement waterproofing when one of the houses he built developed a cracked foundation wall that was leaking water into the basement.

After some research, Larry decided that there had to be a better way to waterproof homes than the technology that was currently available. As a result, Connecticut Basement Systems, Inc. was born in 1987, with Basement Systems, Inc. and product development following in 1990.
