Once again a very pleasurable technician was here. He not only explained before what was needed to be done but after showing me what he did and why. I’m very pleased with this company! I appreciate knowing ahead of time who was coming and then followed up with a call telling me when he would arrive. Thank you!

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!
