We had our basement waterproofed by B-Dry before remodeling. They forgot to pull the permits (error on their part -- extremely frustrating!), but the owner spent the entire day down at the city pulling permits to get the job done. Of all the waterproofing companies we contacted, B-Dry had the best solution at the best price (though it was still extremely expensive!) We live in Del Ray, where wet basements are extremely common; my biggest complaint is that they only recommended waterproofing one area of the basement -- now we're having leaks in a different area. We'll be calling them back!
