Marvin called Rainy Day to get an estimate, so we sent out Rainy Day’s Ed Upenieks to his location in Sumas, WA, to help design a waterproofing...
Job Stories From Sumas, WA
Basement Waterproofing in Sumas, WA

Marvin’s semi-finished basement in Sumas was periodically leaking in water during heavy rains. He was in a hurry to fix it before beginning his home remodel, so he allowed Rainy Day the opportunity to repair his wet basement permanently.

 

Our solution was to install WaterGuard around the perimeter of the basement. WaterGuard is a sub-floor perforated drainage channel used to help collect and discharge water through a high-capacity sump pump system. We installed our TripleSafe sump pump in an airtight basket to prevent clogging with three pumps in one, including a battery backup pump, to handle any potential water leaks.

 

Marvin can now enjoy peace-of-mind with a dry basement and healthy living space.
