Why Do Washington Basements & Crawl Spaces Get Wet?

Flooded basement: When it comes to precipitation, the state of Washington has some of the rainiest regions in the world. Seattle, for example, has a reputation for frequent rain, with an average of more than 150 rainy days. This can easily lead to flooding. When flooding hits your area, your basement is most likely to be the prime target for water damage.

Other wet basement signs: There are many possible sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.

    John's Waterproofing came out and encapsulated my crawlspace two years ago. When I decided it was time to finish my basement, they were the only company I called. Throughout the process the crew has been very respectful, clean and thorough. They made sure that my entire basement was sealed off and covered in plastic so that they did not get dirt or mud anywhere in my basement during the process. Manuel answered my questions when I had them and did not mind when I popped my head in to check on their progress. I was very happy with the work they did. Now the space fits with the rest of my finished basement.

    The service technician, Claiton, is a good company representative. He took the time to clearly and precisely explain all of what he did and was going to do. He was enthusiastic and ambitious. It impressed myself and my wife so much that we had to tell the company. As someone who is over ninety, we know how important it is to tell people when they did great work.

    I do think that one of the piers was not cut off at the top properly and the removed patio cobblestones did not fit back into place and I paid someone to come in and cut and place new cobblestones. But I had to have someone come in anyway because when the sunroom floor was leveled it was raised up to the point of being obvious from the outside. I am overall very happy with the projects.
