Our house is a historic house within a set of historic houses built in the 1850s. At Christmas this year we had a problem with the sewers backing up we called Lemmon. They came on Christmas eve. There was very little information available and the pipes are very old. They were able to resolve our problem without causing any damage to the house and were very careful not to create a mess. Their attention to the unique situation was key to investigating and solving the problem. My only issue is that the problem might have been solved faster. But overall, great job. Thanks Don!
