    Basement Transformation in Yonkers, NY

    This Yonkers, NY basement was cold, dark, and cluttered. With unfinished floors and walls, the homeowner rarely used the space, and felt that it was being wasted as a storage area. He wanted to get more out of his basement, so he called the experts at Total Basement Finishing to learn more about his options. 

    Soon after, Sales Representative Ralph Cioffi traveled to the home to assess the basement. He quickly inspected it and devised a plan transform the basement into a beautiful living space. He then spoke to the homeowner, and together they discussed how the basement would be finished. Pleased with Ralph and the plan for his new basement, the homeowner decided to move forward with the project. 

    On the first day of production, Basement Finishing Foreman Erik Dobrzycki  arrived to begin the transformation. He installed ThermalDry Elite Planking, which snaps in place right on top of the existing concrete floors. ThermalDry is impervious to water damage and mold growth, and comes with a built in thermal break that keeps floor temperatures up to ten degrees warmer than the concrete below. Then he installed EverLast walls, which helped to brighten the room dramatically, and come with built-in rigid foam insulation that helps to keep the basement warm and energy efficient. 

    When Erik's work was done, the homeowner was thrilled with the results. He could hardly believe how his basement had been transformed into a beautiful new part of his home, and knew that he would be able to enjoy this new space for years to come.

    WaterGuard System in Hastings-on-Hudson, NY

    This basement had a constant water problem that would disrupt the functionality of this home. Tired of a wet basement, the homeowner decided to call Connecticut Basement Systems for a permanent solution. 

    The solution to this basement was to install a full perimeter WaterGuard system to prevent water to enter the area. This system is installed around the perimeter of the basement and will collect water internally and channel it to the sump pump. The sump pump will then discharge the water away from the home. CleanSpace liner was also installed on the half wall around the basement to prevent any moisture or water from the coming through the walls. (You can see the liner in the after photo) This is exactly what the homeowner wanted and was pleased with the results!

    This company in Scarlsdale, NY was in need of a new waterproofing method, as their old sump pump was beginning to back up, causing their basement to flood and become damaged. They needed a permanent solution, so they decided to give Connecticut Basement Systems a call!

    Our System Design Specialist, Rick Raucci, came out and quickly offered a fool proof solution to their water damage problems. Kryz Wilk and his team came out and they got right to work! They first installed our SuperSump along with the UltraSump back up battery. The SuperSump is a top-rated Zoeller pump, and is designed for high reliability and pumping. By adding the UltraSump back up, the battery-powered pump will come on automatically if the primary pump isn't doing its job for any reason. To make the space look cleaner and brighter, we went ahead and installed our CleanSpace Vapor Barrier. This will reduce moisture and humidity in the space, and will help seal out cold drafts this upcoming winter!

    This company now has a cleaner, much safer space, and we were happy to provide it to them! Give us a call TODAY for your free waterproofing estimate!

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
