When we arrived at this crawlspace, it was humid and leaky, and there were puddles of water on the ground. To stop groundwater from seeping into this home, we encapsulated the crawlspace with our CleanSpace vapor barrier. CleanSpace is a very durable liner that water cannnot pass though. This crawlspace is now dry, and will remain so for years to come!

This crawlspace used to be a major contributor to the high energy bills in this Westport, CT home. Unconditioned air would leak into the crawlspace and then up through the house. We insulated the space with our SilverGlo rigid foam insualtion. SilverGlo combines highly effective graphite-impregnated insulation with a built-in radiant heat barrier surface, and seals walls from outside moisture and humidity. We were able to make this home more comfortable and save the owners money by insulating the crawlspace!

This Westport, CT crawlspace used to be drafty, wet, and humid. To keep it dry, our team encapsulated it with the CleanSpace liner. The CleanSpace liner acts as vapor barrier, while underneath it, our drainage matting redirects any groundwater to a sump pump system. After installing our crawlspace waterproofing products, this basement remained dry for years to come.

Job Stories From Westport, CT
Basement Waterproofing in Westport, CT

A customer in Westport, CT had water seepage in their basement, so they gave us a call at Connecticut Basement Systems to have us solve their problems. One of our Sales Consultants, Alex Lopez, went out to the home to assess the basement water issues and propose a solution that would eliminate their issues, keeping their basement dry. 

One of our Foremen, Antonio Diaz, and his crew installed this job. They installed our WaterGuard drainage system below the floor, around the entire perimeter of the basement, to collect the water coming in from below the floor and the walls. Then they installed our TripleSafe sump pump to take the collected water and pump it out of the home at a safe distance. It uses three pumps; a primary, a secondary, and a battery backup that can pump 11,500 gallons on a full charge. They also installed a half wall of CleanSpace vapor barrier to help lead water coming from the walls into the drains below. With these systems, this basement will stay dry, giving the homeowner peace of mind. 

CleanSpace Liner in Westport, CT

This Westport home had a crawlspace that had a lot of moisture and a musty odor. This caused concern for the homeowner because it was starting to affect the living area of his house. He wanted to transform his crawlspace area to be an energy efficient place. After doing much research, he decided to call Connecticut Basement Systems as they are the experts in crawlspaces and basements.

On the day of the appointment, Sales Representative Rick Raucci arrived to inspect the crawlspace. It had a lot of cracks and openings which is how moisture was able to enter the crawlspace so frequently.  Rick recommended installing a CleanSpace liner to cover the walls and floors of the crawlspace. This durable product will prevent air and moisture from entering the crawlspace, leaving the area drier. To address the musty odor, a SaniDry can be installed to control the humidity of the area. With controlled humidity, the air quality will dramatically increase to be healthier and safer. This is exactly what the homeowner wanted and decided to move forward with the project.

On the day of production, Foreman Garfield Sanderson and his team installed the two products proficiently and effectively. The homeowner was extremely impressed with the transformation of the crawlspace and even more impressed with results of the efficiency of his home!

Project Location: Westport, CT
Unfinished basement has flooded occasionally since the house was built in 1958 (we are original owners). Property abuts a tidal swamp and springs run under the house. Flooding has become more frequent and extensive: on 1/13/2024, for the first time, the entire basement was flooded with six inches of water. Our objective is not to completely eliminate flooding but to install a means by which to automatically pump the water out and dry the basement when flooding occurs.

We are noticing that our basement takes on some water during heavy storms; we believe that this is partly due to older and clogged gutters (we are replacing all gutters this month). We would like to ensure that we prevent water from coming in and prevent any mold formation.
