Building Finished Basements that Last

1. You want to have a comfortable, beautiful finished basement, BUT you want it to last!

2. Most contracting companies use standard “above-grade” materials which is a recipe for disaster. These materials end up with mold and mildew and you have to tear out the whole basement and start over.

3. Total Basement Finishing contractors eliminate these problems by only using completely waterproof, inorganic & mold-resistant materials that are designed specifically for basements. You will have the basement you've wanted and it will last long as your house.

    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.

    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!

    Moisture is the enemy of every home. Building code requirements are not enough and do not adequately allow for controlling moisture in a crawl space or basement evnironment. CleanSpace Northwest's Baement System and Crawl Space products should be in every house. It is simply the best products for creating a healthy and efficient environment within a home. Basement Systems' science behind their product is well-proven. I recommend CleanSpace Northwest and their Crawl Space and Basement Systems products to everyone.

    I would like to express my appreciation for the outstanding service I got from the three gentlemen that transformed my crawl space under my house to a white place fit for a wedding (if we were all very short...haha). Their professionalism and unbelievable hard work for hours and hours is amazing to me. It was worth every penny I paid to get such fantastic results. Clean Space Northwest is very fortunate to have such dedicated workers whose only goals are to get the job done and do it right. They definitely did it right and I will be spreading the news to all my friends.Please thank them again for their efforts. I will be calling soon to set up some time to get flooring in my basement (that will never be flooded again because of their efforts).Sincerely,Linda
