Your Home faces Water Damage

1. 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.

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.

Testimonials
  • "Taking back our garage to house cars!" Read Full Testimonial

    Larry K. of Kitsap County, WA

    Customer Testimonial

              One of the things we liked about our house was the ability to store items in the crawl space, thus freeing up the garage to do what it's supposed to do - house cars. In order to do so, we needed to replace the worn plastic and musty smell. Seeing an advertisement for CleanSpace, I contacted them shortly after purchasing the home. The representative was fantastic in understanding our desires and explaining our options. He took the time to explain the CleanSpace system, how it would be installed, and what we should expect from it in the future. We had the system installed and we are quite happy we did. First, it eliminated the musky smell and any potential for mold. Second, it provided ample storage space for us putting boxes, furniture, etc. in our crawl space. Even though the material seems thin, it is rugged and durable to handle walking on it, and stacking heavy materials such as boxes, pieces of wood, etc. Third, we had an issue with the dehumidifier being too noisy but the technicians returned several times to provide a quieter solution. It was achieved and after almost eight months in operation, we don't hear it. Fourth, the installation staff was exceptionally professional and removed unwanted debris from underneath the house. I would wholeheartedly recommend the CleanSpace system to anyone regardless if it is a new home or one that has seen the test of time and Washington weather. They system works.

    Cathy G. of Tiger Lake, WA

    Customer Testimonial

              Our lake home leaked so badly, I cried every time it rained. We had inches of water in the basement. My stepson, a civil engineer, said we should call CleanSpace NW. The crew from CleanSpace NW was prompt and finished on time, saving us from abandoning half of our home, by fixing the water problem. Every time there is a hard rain, I run downstairs to check and it's dry! CleanSpace NW is the only way to go!

    Our experience with TerraFirma was great from beginning to end. They were very fast, efficient, clean and courteous. We had the crawlspace encapsulated and our whole house smells and feel better. No more mold and bowed floorboards. And they were cheaper than the competitors.
