About the Founder

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.

Patented, Awarding-Winning Solutions

Basement Systems® currently holds 31 patents on its innovative waterproofing products, with a full-time Research and Development department working every day to discover and design new and better basement waterproofing products. We have dozens of waterproofing products available to each of our dealers, with new ones being developed all the time.

Over the years, we have won more than 40 awards for quality and innovation in our industry from the Connecticut Quality Improvement Award Partnership. Basement Systems®’ wet basement and crawl space systems have been installed in over 200,000 homes across the network, and they've proven the superior solution for waterproofing and moisture control.

Each of our waterproofing products includes a written warranty, which is fully transferable to the next homeowner.
