    Terrible experience with Gateway Sewer & Drain. I paid $542 in labor plus $225 for a camera inspection, $767 total, and they still couldn’t resolve the problem or even locate the outdoor access/cleanout line. I hired Tope Plumbing, and within about 15 minutes they located an outdoor cleanout roughly 5 feet from where Gateway had been working. They hydro-flushed the line, cleared the blockage, and got everything flowing again for $305 within 1 hour. Almost $800 with no resolution vs. $305 to Tope to actually find the access point and fix the problem. Stay away from Gateway.

    They do a great job. Very professional and communicate well. They’ve been able to come out quickly and complete the work in a timely manner.

    Peyton was great, friendly, quick and efficient. He diagnosed and resolved the issue promptly and made sure everything was cleaned up before leaving. He also shared helpful tips on maintaining the garbage disposal and preventing future issues. Really appreciated his professionalism and helpful attitude.

    Quick, easy, and professional. Trevor came out to cable for roots and did a great job. Happy to support a union business and will use again.

    Scheduled a PM for a floor drain week prior. Sam O. arrived on time and was courteous and efficient. I will continue using Gateway Sewer & Drain as a preferred vendor.

From the Google listing, checked 30 Aug 2026.

Most reviewers describe drain and sewer line work. Customers mention roots cleared from a line, a floor drain serviced on a set appointment, and a garbage disposal problem diagnosed and fixed. Several say the crew came quickly and cleaned up before leaving. Tom wrote "Found and cleared issue" after calling them out. Reviewers name the technicians who came, including Peyton, Trevor, Sam and Jason. One customer, Alex, had a different experience: the problem was not resolved after paid labor and a camera inspection, and another company cleared the line.
