I had evidence of moisture coming up from my concrete slab. I called and. was able to get an appointment the next day. Deagan was very efficient and helpful.

He provided additional info that was very helpful to me on how to proceed with the next steps, even though it was not part of his job. I highly recommend this company and, in particular Deagan. It is refreshing to see honest and hardworking professionals.
