Job Stories From Larchmont, NY
Waterproofing in Larchmont, NY

A homeowner in Larchmont, CT was having water issues in their below-grade garage. They decided to call us at Connecticut Basement Systems to solve their problem. After scheduling an appointment, one of our Sales Consultants, Rob Anderson, went to the home to estimate what this customer would need. He informed the homeowner that they would need our waterproofing products to prevent any future damage. After this, it would soon be time for one of our Foremen, Krzysztof Wilk, and his crew to tackle this project. Based on Rob's proposal, they would install WaterGuard along some of the sides of the space. They would also install our TripleSafe Sump Pump in the corner where the water collected from the WaterGuard would go. Then, that would get pumped out of the discharge line into the lawn at a safe distance from the house. Now that their below-grade space is waterproofed, there's no more worry about water damage!

Flooded basement !
Project Location: Larchmont, NY
We just moved into our new home a week ago. After a week of rain, the basement stayed dry. However, last night, after a full day of torrential downpour, water came up from the ground, leading to roughly a half an inch of water in the basement. We would love to understand what our options are to keep the basement dry in the future, as well as the associated costs.
