"Our foundation was seriously compromised due to water intrusion. Steve responded quickly and gave us an estimate at a great price. He was knowledgeable and informative. Dan and his team repaired our foundation, installed a drainage system and pump, as well as a vapor barrier. Our basement has been dry and free of mold since. The project was completed in a matter of days. I couldn’t believe how quickly they worked. I recommend the gurus to everyone who needs basement repairs. Thank you again!!!"

"They responded quickly and had someone out to inspect my basement quickly and at a convenient time. They inspected my basement and recommended an $8,000 treatment. Everything they said made sense and the materials and methods they specified seemed appropriate. That was more than I wanted to spend, so I decided to try a DIY fix first."

"The required fix required that outside trenching be done and B-Dry does not do this type of work. The representative was very knowledgeable about the problem and apologized for not being able to solve the issue. Very much appreciated his honesty."

"PRO: For installing an interior French drain, while it was pouring outside, the crew was extremely clean. Both my yard and interior of my house was left with only minor evidence of the work. PRO: The initial consultation with Phil Thistle was informative and provided me with piece of mind in terms of the project and projected outcome. It seemed as though we would have support throughout the project. PRO: Owen Dan Kelly is very dedicated to the quality of his company and the work they do. Once he found out about some of the concerns I had with the project, he remedied them immediately. I was very impressed with the attention he provides his customers. CON: Communication. Up to the install, I was in constant contact with the company about timing and expectations. However, as soon as the install began and then directly after, I was on my own. There seemed to be no one overseeing the install, just the crew doing the work. Also, there were miscommunications about the project throughout the install; the crew was asking me for direction on installation steps I have no background on. CON: Support. Again, as soon as the install was complete, that was it. Phil showed me images of pictures he took with satisfied customers on past installs, making me feel that he was dedicated to the project's success. However, after the consultation, even though he was copied on various emails about some of my concerns, he never got back in touch. In addition, no one ever contacted me to see if I had questions about the finished product, to see how everything turned out, or if there was anything else I needed. CON: Timing. The crew was on-time for the install both days, however, the schedule was more impactful to my routine than expected. The crew worked 9AM - 3PM only on Day 1. However, to finish in 2 days, they worked 8:30AM - 7:30PM on Day 2. As I have a small child, having construction still happening after 7:30PM was difficult, but more so was confusing as Day 1 ended so early."

"All went well except for one misunderstanding, which I covered with another subcontractor. Project, as finished, is/will be almost completely invisible, which they went out of their way to help me accomplish. Very happy with price and job. And, most important, my basement is now dry!"
