"I received a call instantly. They scheduled the repair the same day. Once they reviewed the problem, they gave me a quote and completed it within 2 hours and at the cost quoted. Stephen was helpful with pictures and explanations and cleaned up after he was done. I would recommend Mr. Rooter and Stephen to anyone."

"The owner actually took the time to brainstorm with me regarding a bad case of the "drain flies." I found him to be very helpful. This company ended up sending some other company out to do the job needed. They sent a very qualified & professional company out. I will use this company in the future and will not hesitate to call on Septic Designs also, for my larger Septic needs."
