Project Location: 11th Ave NE, Issaquah, 98029

Comment: We are looking for a new house, and the inspector who did the house inspection told us that the crawl space has 16% moisture. Also, it has only 8 vents currently installed. However, the walls do not have any rot. We wanted to know what is the right way to fix this potential problem and how much will that cost us?

Project Location: SE 111th St, Issaquah, 98027

Comment: We already have clear plastic on the entire floor of our crawl space, but I am wondering if we need added protection. Our first floor is alway quite chilly and we are wondering if you product would help keep that area warmer. Also, how well does your floor covering hold up to flooding. We have had as much as 6 inches of water in our crawl space before.

Project Location: Mt Olympus Dr SW, Issaquah, 98027

Comment: We have some standing water under an extension we built on to the home 7 years ago, we need to identify if the water is just standing or perking up.

Project Location: Wildwood Blvd Sw, Issaquah, 98027

Comment: WE live on a mountainside with an attached garage. This causes a lot of dampness in the lower level of our house. It stinks! We have a system in our garage already but it is small and doesn't help. I can't stand the smell and the thought that all of our garage storage may be molding and damaged.

Project Location: SE Mirrormont Blvd, Issaquah, 98027

Comment: Water into the basement from an unknown source. We have prevoiusly worked with Basement Systems on another area.
