Sewer backed-up into basement bathroom. DrainWorks arrived 1.5 hours after initial phone request for service. Serviceman was polite, efficient and respectful. Within an hour or so he had diagnosed the problem, provided a temporary fix and recommended a permanent solution. One day later, over about seven hours, a crew dug a ten foot hole by hand, replaced the pipe, re-filled the hole and cleaned-up the work site. That evening, final inspection, payment and sign-off occurred. Everyone I dealt with, both on the phone and in person, was professional, helpful and honest. Great job at a fair price. I would strongly recommend use of the DrainWorks to others I know.
