"All utilities were located prior to work. Permits were taken care of and completed. Sanitary facilities for the crew were placed and removed promptly and placed so they were not a problem. The crew was courteous and prompt and did the work in a professional manner. They even did a little bit of extra sealing of the sites of foundation cracks in the affected area and pointed out a couple of things I was unaware of in the crawl space of my house that needed my attention. When the work was complete the clean-up was exceptional.

"A technician named John did a crawl space inspection and said I had no mold and no rodents and did not need their services. He was professional, friendly and honest. i just received a quote for $12,000 from another contractor for work that did not need to be done or that I could do myself."

"Being on the coast and close to wetlands, there is a ton of water accumulation in my crawlspace. Terra Firma had a ton of work to dig out the drainage trenches but they did a wonderful job! They had a large crew that tackled different projects to get it all done in 1 day. Everyone was professional and very friendly. I will definitely use them again for my continual foundation improvements."

"I was glad John's Waterproofing was recommended to me to resolve the serious water problem in my large crawl space. With Jake's Design and Jeremy's remarkable crew, who were able to efficiently perform the many tasks needed to fix the problem, I now have a dry, clean and healthier crawl space under my home. Thanks to John's superb 5 star Company! Virginia Rossman"
