"They responded quickly and came by my house the same day I called them. Lou and Al, the owners did the work themselves along with another worker and they were a pleasure to work with. They installed a sump pump for us, removed mold from a crawl space and under carpet, and removed some older make-shift equipment that had been installed by previous owners. They explained everything carefully and I think gave us a very good price for the work performed. They did not try to scare me or convince me we needed unnecessary work done, which they easily could have done! Overall I am completely satisfied and will definitely use them again, great company."
