We needed help on a clogged drain that caused a disaster in our kitchen. We live in Towson and the only emergency plumber we found that could get there the same day was Baltimore Sewer Service.They showed up, even though we didn't call until after 9 pm. They took a look gave us the price on drain cleaning and went to work on the problem. 45 minutes later they were done and pipes were clered and the disaster was over. Very helpful and nice will use again if needed.
