Job Stories From Port Hope, ON
Basement Waterproofing Job in Port Hope, ON

Allan W. never thought that the reason he wouldn’t be able to enjoy his retirement would be because of his home in Port Hope, Ontario. After working hard all his life he just wanted to travel, but his leaking basement wouldn’t let him! Every time he left to go away somewhere, his basement flooded, ruining all his personal belongings. After a few times of this happening, he couldn’t travel anymore, as he worried his basement would flood when he was away. Allan knew the problem needed to be resolved, so he called Clarke Basement Systems.


Steve Matthews, System Design Specialist, went to Allan’s home to help solve the problem permanently. He noticed that the water was coming in from the old concrete floor and left the basement smelling musty. Steve put together a solution to Allan’s problem that would guarantee water would never come in again! Jose Martinez, the lead foreman on the job started by installing a CleanSpace® Vapor Barrier System to not only catch water but contain the musty odor. Once the water is in the CleanSpace®, it is then funneled down to a full perimeter WaterGuard® system which drains all the water to our patented TripleSafe™ Sump Pump System. The water is pumped out and away from the house, leaving the basement COMPLETELY dry!


It is safe to say that Allan can now enjoy his retirement and continue to travel without worrying about his home.

I took possession of my new home on October 24th. After the first rain on Sunday, a lot of water came into the basement. I had an inspection done before I bought the property. The report suggested that there may be seasonal dampness, but this goes well beyond what I expected. The basement was very very dry at the time of inspection. There is a sump pump in the basement, but the water didn't reach to that area. Thank you, Maureen.
