Working tirelessly to solve a 20-year, occasional kitchen sink backup problem due to plumbing conforming to a construction issue, BJ spent Friday night to stabilize the problem and returned Saturday to map and solve the problem, including implementing clean-outs to facilitate easy access in the unlikely event of recurrence. Fully professional and explained the problem and solution in such a way that I was pleased to write the check. LimRic handles all of our plumbing and has handled our HVAC requirements for years.
