Dan S. says, "We could not be happier with the work Del-Val did to waterproof our basement.We had work done by another company about a year ago to stabilize our foundation, and ever since then weve had water intrusion with almost every rain and flooding maybe every month or two in the spring and fall. Our existing sump pump was not up to the task of handling how much water ran under the house. Another company quoted one solution, but Del-Val offered work that was both more comprehensive and at a lower price.Everyone involved was very friendly and helpful, and they explained to us what they were doing before, during, and after. At the end of the work, our basement was clean and neat, and most importantly, dry. Weve just gotten an inch of rain in the last 24 hours, and there has been no water intrusion whatsoever."See more
