"David and Cody from John's Waterproofing went straight to work; they quickly found the problem, showed me the problem, discussed what would have to be done to fix the problem, fixed the problem, then thoroughly cleaned up. Very nice people to work with, from the schedulers through the technicians."

"We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that though ;)"

"Schyler arrived at the appointed time explained the the process and how the equipment worked. After he finished he walked me through the completed work. He had cleaned up all the leftover residue explaining if there was any further movement in the work there was a five year warranty and he would return to correct it at no additional cost."
