Arrived on site to clear main sewer line through outside clean out. Attempted to clear line with 300 machine multiple times and kept getting stopped at the same point. Attempted to camera line, unfortunately there was no visual due to the line being full of water and debris. Located point that we were not able to get past. Due to not being able to get past a certain point we recommend excavating are to gain access to pipe in order to scope rest of sewer condition. Provided estimate to customer for work described above. Customer will contact us when available to come out for work due to front house being worked on.
