Before and After Pictures from St Thomas
Wet Basement Cold Storage Area, St. Thomas ON

Wet Basement Cold Storage Area, St. Thomas ON Wet Basement Cold Storage Area, St. Thomas ON

Problem: An unfinished cold storage area is a great place to store items to keep cool, such as canned food, even in the warm summer months. Although closed off from the rest of the house, if there’s water penetrating any area, it creates a damp, humid and unhealthy environment which affects the entire home in what is known as “The Stack Effect”.    

Solution:  We installed a French drain system on the problem walls in the cold storage area, added a powerful sump pump with a battery backup for improved drainage and reliability and finished it off with our BrightWall® rigid basement wall system. Now this cold storage area is dry, heathy and will look fantastic for years to come.

Problem:  Even newer homes can have problem basements. This basement often felt damp and smelled musty. Excess water vapour was entering the space from the unsealed sump pump lid.

Solution: To help control humidity, we installed the super quiet and efficient SaniDry™ Sedona Dehumidifier. It’s connected directly to their updated sump pump system, so with regular maintenance, these homeowners will never have to worry about excess moisture or a damp feeling basement again.
