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.
