I highly recommend Seidel Plumbing; I have had great experiences with the company and specifically the owner Otto Seidel. Reading the prior reviews I get it..Otto is an old school DC Plumber, he can come across as gruff. But, if you can handle that, call Otto. You would be hard pressed to find a better and more knowledgeable plumber in the DC area. I have a VERY complicated sewer issue, lines tied with neighbors, overgrown tree roots growing into sewer lines that have been around for over a century, DC Water aware of the longstanding problem but unwilling to fix it. It has all of the intrigue of a day time soap opera - betrayal, hope, despair... honestly, a hot mess. The only person who was able to come in, explain the issue, and put forth a workable solution was Seidel Plumbing. Otto Seidel was on a short list of plumbers recommended off the record by a foreman at DC water who has been around for over 20 years. Calling Otto was the best decision I have made in this saga. He gave me a short term solution (install and external clean out) to stop the sewage from coming up in my basement (yes, it's as disgusting as it sounds) and charged $2500, $8K less than the nearest competitor. He offered a long term solution to repair damaged parts of the sewer for $10K, which is $45K cheaper than the nearest competitor. Best of all, he showed up the day I called and he finished the job in one day. So, to reiterate, if you are looking for and are interested in paying the premium for a lovely customer service oriented experience with friendly admin and schedulers, call Magnolia - but expect to pay 3-4X the cost of the repair for that overhead. If you want an experienced DC/MD plumber who has seen it all and can do it all who will give you a fair price and an honest days work with no frills - Call Seidel Plumbing!
