In this garage we installed Waterguard and a SuperSump pump to prevent any further water problems. On the walls we installed our CleanSpace liner to make the walls look nicer. On the outside of the house we installed Iceguard to prevent water backing up from frozen pipes during long winter months.

This Yorktown Heights homeowner had a crack in her basement that was allowing air and moisture to flow through. The homeowner wanted to find a permanent solution to fix this problem. She did her research and trusted the experts at Connecticut Basement Systems. 

The solution was to install a FlexiSpan System to the wall crack. We first put a port at the bottom of the crack below the floor to create a way for water to properly reach the sump pump. Then, the polyurethane sealant is applied to the crack where the crack becomes more deep to form a durable, flexible seal. This system effectively stops any leakage which is exactly what the homeowner wanted!

Basement Finishing & Remodeling in Yorktown Heights, NY

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Yorktown Heights contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

Job Stories From Yorktown Heights, NY
SmartJacks in Yorktown Heights, NY

This Yorktown Heights home had sagging floors that concerned the homeowner. She wanted to find a solution and decided to trust the experts at Connecticut Basement Systems as they have a foundation division and made an appointment.  

On the day of the free, no obligation appointment, Sales Representative Brad Glazer arrived at the home to inspect the problem. He assured the homeowner that this was a common problem due to weak soil. Thankfully, there was a solution that we offer and Brad further discussed SmartJacks. SmartJacks are steel supports that are used to stabilize and level the floor joists in a crawl space. Brad assured that installing them in the crawl space would be the right solution. The homeowner agreed and moved forward with the project to stabilize her home.

On the day of installation, Foreman Victor Alves and his crew installed 4 SmartJacks in the crawl space. This is the only solution that addresses the soil problem directly. Once the project was completed, the homeowner was relieved that the floors had been stabilized and feels more secure in her home.

Hello, I would like to have my sump pit and pumping system replaced in a home I recently purchased. The existing pit houses a submersible AC pump and a backup DC pump; it is corrugated metal lined, has no cover, and is likely original to the structure (~50 years). Please provide an estimate on the cost of replacing this pit with a new plastic lined pit with a cover, as well as replacement of the existing pumps with new 1/2 HP pumps. The existing discharge plumbing does is PVC and does not require replacement.

Hi, We have a crack in our foundation. During very heavy rains, we get some seepage inside.

We have cracks throughout our garage concrete and in the last week we have had some water slowly seeping in the corner of the garage near one of the cracks and wall.

Seems to be water puddles coming from behind my oil tank in the garage. I can't see behind the tank cause the tank is so flush against the wall. Big puddles of water and condensation all over the floor.
