Connecticut Basement Systems Before & After
  • WaterGuard System in Hastings-on-Hudson, NY

    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!

    Before, this Hastings on Hudson, NY crawl space was filthy, smelly and had a dirt floor. This combination led to a moist and unhealthy environment which would affect the rest of the home. The homeowner wanted to transfer her crawl space into a dry and healthier area. With this vision in mind, she trusted the experts at Connecticut Basement Systems who special in crawl space issues of all types.   Now, this crawl space is transformed into a clean, dry and healthy area! CleanSpace liner was installed on top of the dirt floor which will act as a moisture barrier and give the crawl space a clean finish. SilverGlo insulation was installed on the walls of the crawl space. This 2 inch insulation with a radiant barrier will both insulate and reflect heat back into the crawl space. Lastly, a SaniDry Sedona was installed and placed into the area. This dehumidifier will keep humidity below 55% ensuring that the air quality will be cleaner and healthier. The combination of all of these products created the exact crawl space that this homeowner wanted!

    This basement was in need of repair. We put in a WaterGuard and TripleSafe Sump Pump to remove water from the basement. Once waterproofed we removed the water damaged walls and installed Cleanspace walls to prevent any futher water damage.
