Case Studies From Sumas
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.

We need the insulation underneath the house removed and replaced.

We just had our home inspected and were informed we need to have our crawl space cleaned of debri, our pipes insulated, and new plastic laid down.

Plumber says I have rodent problems and need to have access holes repaired.
Vicinity of Cleveland Street in Sumas
I have had someone come to inspect the house for a musty smell and they determined it was coming from an improperly installed/old vapor barrier. They have given me an estimate of what they would charge to have their crew redo the barrier, but I would like to get more than one quote to ensure I get the best value for the investment. I would appreciate knowing what you are able to do. Thanks, Emily
