Waterproofing in Woodstock, CT

This Woodstock, NY homeowner was experiencing water entering his basement frequently. Frustrated with a wet basement all the time and the musty smell as a result of it, he decided to reach out to the experts at Connecticut Basement Systems to help find him a solution. 

On the day of the appointment, Salesman George arrived at the home to conduct an inspection of the basement. He concluded that the best solution for this basement would be to install a WaterGuard system. This below the ground system will collect water internally and direct it to our SuperSump pump. From there, the water is discharged away from the home. In order to address the musty smell and to improve air quality altogether, a SaniDry Sedona dehumidifier to keep humidity low at all times. This is exactly what the homeowner wanted and decided to move forward with the project. 

On the day of production our foreman and his team installed the products proficiently and efficiently. The new WaterGuard system will ensure a dry basement and the SaniDry Sedona will ensure better air quality. The homeowner was pleased with the results and was happy that he called the experts.
