Recent Review: Called company around 8 a.m, and received a same day appointment for 11 a.m. Technician called me and advised me he was running a little behind, and arrived at the time he stated that he would. He quickly assessed the problem, provided a written price quote, and immediately went to work. Within minutes, water through the previously backed up sewer line was flowing smoothly. All three technicians from Texas Plumbing Diagnostics were very courteous and respectful. I will definitely call Texas Plumbing Diagnostics again for any future plumbing needs.
