Had three plumbers provide estimates. George Brazil was by far the most expensive - to rip up one small area of our driveway to fix a service line was estimated at $1,248 by George Brazil (the $42 estimate fee would be waived with service), and $750 by another plumber (free estimate and whom we went with, and had great service - ended up only being $450 when we were done). We were also quoted by another plumber that estimated $1,200 as well, but their (free) estimate was to rip up most of the driveway and replace the whole pipe - far more work than GB.
The plumber from GB definitely seemed professional and qualified, but I agree with several other reviewers here - their pricing is very expensive.
