Pipe to city was failing. Neighbor’s already failed and that repair by another company was six times as expensive. Decided on Trenchlesss before my pipe totally failed. Had it lined in one day after camera inspection and scheduling. Camera revealed imminent failure not too long in the future. One day in and out. Lined pipe stronger than original and no root intrusion. If I waited till the pipe failed would have had 1000’s of dollars worth of hard scape removal and replacement problems.
