Job Stories From Simsbury, CT
WaterGuard and ThermalDry Flooring in Simsbury, CT

This Simsbury basement had water issues that concerned the homeowner. She was unhappy with a wet and gross basement and wanted a change. After reviewing all her options for different basement waterproofing solutions, she decided to trust the experts at Connecticut Basement Systems. 

On the day of the free, no obligation appointment, Sales Representative Glen Knafel arrived at the home to inspect the basement. He instantly noticed that there was a water problem that could be solved with our WaterGuard System. Upon further inspection, the homeowner had expressed that flooring was a concern since it was old and constantly became wet due to the water issue. To solve this problem, Glen suggested ThermalDry flooring which is our waterproof, mold resistant and attractive flooring option. After thoroughly reviewing the plan, the homeowner decided to move forward with the WaterGuard and ThermalDry products. 

On the day of installation, Garfield Sanderson and his crew installed the WaterGuard system professionally and efficiently. This system collects water internally and channels it to the TripleSafe sump pump where it is discharge away from the home. Once the waterproofing of the basement was completed, Foreman Kevon Barnett installed the ThermalDry flooring. This is exactly what the homeowner wanted and was pleased with the entire process, from sales to production and now has a peace of mind that his basement will stay dry all year long.
