"Note: this review is long over due. I've used SWAGS before for plumbing repair work at my house. So, when my parents were having plumbing problems, I called SWAGS. I'm glad we did after the running toilet repair was completed, the technician noticed a problem with how the toilet sitting. After further investigation by Jaime and his team, it was determined the sewer line was no longer connected to the toilet in the upstairs master bathroom. Turns out the sewer line pipes used back in 1975 were defective and now needed to be replaced. As a result, Jaime gave a thorough explanation of several options for repair to my father. Once it was decided which one would work for them, Jaime and his team began the work. My father was very impressed with how professional the team was. If he had question, Matt, the lead or another technician would provide a detailed answer. They would even show him pictures of the defective pipes and the damage it had caused. Considering my parents required to have the master bathroom functioning at night, the SWAGS team completed the work in a timely manner. My father was very happy with the work done and stated he would definitely use them again and would recommend them to his friends."
