Job Stories From Chappaqua, NY
WaterGuard System in Chappaqua, NY

This Chappaqua basement had a water issue every time it rained. Water would seep through the floor which would cause the basement to have a musty odor and be an unpleasant environment. This became frustrating to the homeowner and he wanted to find a solution. He decided to call Connecticut Basement Systems since they are the experts in all things basementy!  

On the day of the appointment, Sales Representative Brad Glazer arrived at the home to assess the situation. He concluded that a WaterGuard system would be the perfect solution. Paired with a Triple Safe sump pump. Brad explained the benefits of each of the products to the homeowner. The WaterGuard system is a below the floor drainage system that collects water internally. The WaterGuard system then collects the water and channels it to the Triple Safe sump pump. From the sump pump, the water exits the basement through a discharge line. These are two great products that will ensure to keep your basement dry all year. The homeowner was impressed and wanted the system installed. 

On the day of production, Garfield Sanderson and his team installed the products professionally and efficiently. Once the project was completed, the homeowner was thrilled with the results and could not be happier with his dry, musty odor free basement!

We moved into our house 2 years ago. We get water in our basement and garage during these bigger storms (which are becoming more regular). Our house is built into a hill and water seems to pool from the backyard and then into the basement somehow. It is an unfinished basement and the house is older (like 1930s ish).
