Sewer Restore in Laguna. We were called out to a house in Laguna Beach that had a backed up 4” sewer line running down the cliff the house sits on. Three different plumbers had been there before us to try and solve the problem with little success. We completed this difficult Laguna Beach restore with the Perma-Lateral system in one-day. The homeowners barely even knew we were there restoring their sewer pipe!
