What Your Neighbors Are Saying

“I will be using this company again.”
James was very thorough at checking for issues. It turned out all we needed was silicon caulk that a previous contractor had omitted. So the cost was minimal and there was no up selling.

Brian was very friendly and knowledgeable. He explained the problem, our options, and what his recommendations were. He worked very fast, too, and we ended up paying a little less than what was originally estimated. He also made sure everything was put back together and even cleaned up afterwards. We are very happy with his service and appreciate his professionalism. We’ll definitely look to Intelligent Service again for any plumbing issues. Thank you so much!
