"The only issue was with how the appointment time showed on HomeAdvisor. Drainline does appointment blocks when they could arrive (ex 10a-12pm). We thought we had a 9am appointment but found out we actually had a block between 9-11 when someone could show up. After we got past that, the work was priced well for what we needed and we're happy to have a new pipe."
