Job Stories From Clinton, CT
Waterguard Installation in Clinton, CT

This Clinton, CT home was experience excess water seepage through it's wall, and the homeowner's were starting to become embarrassed by the damage. They gave us a call at Connecticut Basement Systems, and we were happy to come and fix the problem! 

After Bill Anderson came in and inspected the problem, we quickly realized that our WaterGuard Perimeter Drainage System was the soution. Designed to capture water seepage, the WaterGuard® system is hidden beneath a layer of concrete. Only the top edge of the wall flange is visible. Once it is installed, you'll hardly know it's there! It also lines the entire perimeter of the basement, so all water from all walls will be captured. This family now has a drier home, and much more comfort when it comes to spending time in their basement.

We have an intermittent leak in our basement, from one specific area, which appears to originate from outside the house after rain
Project Location: Clinton, CT
I have a "natural area" next to the unfinished basement. It has a metal reinforced section with concrete above that forms the front porch. That concrete has split and is allowing more moisture into the area. It has always had a small amount of water coming into the area, but since the concrete split there is more.

The house that I currently live in was newly remodeled about three years ago. When I had the home inspection done prior to buying the house the inspector said that the floor joists in the crawlspace in one area of the house needed repairs due to over span issues and not having any firm attachments. There have been no issues since buying the house however in the last few weeks I've noticed that a few doors do not close like they used to and appear to be off level. I have a copy of the home inspection with photos of the concerned areas and what he said the issues were and what needed to be done to resolve them

Previous customer at a different home. Old house. Basement floor showing moisture and basement starting to smell mildewy. Have had small 50 pint units that pump out and have worked well, but have to keep replacing every year or so.
Project Location: Clinton, CT
Crawl space has lots dirt so many aspects of foundation and structural columns are inaccessible. The house was built in 1946, as a cottage and so we understand that it might not have been constructed well. There is some water in the basement. Would like a quote to bring the house up to current standards and to ensure that the house is not structurally compromised. Thank you.
