Plumbing Drain Repair

A bathroom tub had a slow leak, so I attempted to snake through the overflow. As soon as the snake touched the overflow pipe, the whole overflow/tub drain fell off into the crawl space under my home! I was disturbed by this, and I knew I needed immediate plumbing expertise - Thumbtack connected me to Mario the Drain Chief. It's was about 2 hours from when I made my initial Thumbtack inquiry to when Mario arrived, scoped the job and provided an estimate. Mario not only addressed the tub drain, but noted that the piping running from the tub to the main drain was held together with rubber gaskets - these gaskets were a contributing factor to the clog in the first place along with the pitch of the drain pipe. We agreed on a price and less than an hour later, he returned with all the necessary materials. About 4 hours total from initial inquiry to job complete. The drains are now all the appropriate rigid black pipe, with correct pitch & code compliant plastic hangars. Thanks to Mario, the root cause of the failure was addressed & the tub drains like a champ. Will hire again for the next plumbing adventure.

The Drain Chief is the best out there, he came prepared, really was able to get the roots out. He knows what he’s doing. Clearing drains since 1985. Highly recommend.

Mario has been helping us with drain issues when they come up, which unfortunately happens periodically, old house lines and all. He is very professional, reasonably-priced and always very polite! Highly recommend!

Plumbing Pipe Repair

Mario 'actually' answered my request online at 3:00 am., when I signed-in to look for a plumbing contractor. Now, that's service! We scheduled the repair the same morning, and Mario arrived 'on-time' as promised between 9am.-10am. The damaged hose bib was replaced and the cost was very reasonable. I would definitely use The Drain Chief again.
