"Jordan was awesome! He initially sent one of his guys out to check for some gurgling and sediment in our plumbing in the basement. They took a good look and found some grading issues with our pipes. Jordan followed up with me after and then committed to coming out himself to determine options. Throughout it all he was very communicative and extremely knowledgeable. We discussed some options and moved forward with the one that made the most sense. The issue was addressed and Jordan followed up later on to make sure everything was still good. Highly recommend Jordan and team dr.drain!"
