Blaylock did a near-complete sewer replacement for us in Richfield, and we were very satisfied. We had three companies out to look at the situation, which was a sewer lateral damaged heavily by roots and one portion of transite pipe that had rotted out. One recommended only doing a spot fix of the sewer lateral, and two recommended redoing the whole line. Blaylock's price was only slightly higher than the one who was just going to replace a small segment!
My only complaint is that they were a little casual about the bid and the scheduling. We never got a formal written bid or estimate, and they took a while to nail down the exact date. (Though, it was not urgent, and they knew that.) But when they actually did the work, they were awesome! They were very efficient, with just two guys working, did almost all the work by noon same-day. They were very careful about managing where they put the piles of dirt, so the lawn was not damaged more than necessary. Since they were ahead of schedule and below budget, they even offered to re-sod where they'd dug the holes, for only a little more money.
They installed a clean-out in the front of the house, and were careful to cut it down low, so there wouldn't be unsightly PVC sticking up. We added a couple new plantings ourselves after they left, and the lawn looked better than before! The final bid came right in the middle of their estimate range, even with the sodding.
Of course, only time will tell if the new line will hold up better than the old, but assuming they're as conscientious about the sewer work as they were about all the stuff we could see ourselves, I have confidence their job will stand the test of time.
Would definitely recommend.
