MGA Plumbing is the Cosby plumbing company to call for sewer backup. Our local plumbers are available 24/7, arrive on time and fix the problem right the first time. Thousands of 5-star reviews from Missouri families and businesses.
A sewer backup is a health hazard. Keep people and pets away from affected areas, don't run water or flush, and call us immediately. We clear the blockage, identify the cause (roots, grease, collapsed pipe, city main issues) and get your drains flowing.
After clearing, we can camera the line to prevent a repeat and advise on backwater valves that protect basements from municipal surges.
Homes in Cosby range from older houses with original galvanized and cast iron plumbing to new construction with PEX — and each needs a different approach to sewer backup. Our Cosby plumbers know the local housing stock, soil conditions and water quality, so you get a lasting fix instead of a temporary patch.
