They replaced my entire sewer line from back yard all the way to the street at my LA home in fall 2007, a $15k job. I found them to be extremely professional, punctual, very considerate, kept a clean job site, communicated well. Most important, they did top-quality work - I know a bit about plumbing, so could tell they we're doing things the right way, not the easy way. They were flexible & accommodating, and explained the process well. I probably could have found someone to do it for 20-25% less, but I've done that before with horrible results - you get what you pay for!! I recommend them without reservation.
