"I had roots in the drain pipe along with a crack in the pipe under my deck. First visit they cleared the pipe of roots and the second visit installed a sleeve through the pipe to prevent future problems. Both visits were very professional and when they were done they provided a camera view. This allowed me to see their finish product. "

McDonough’s is an integrity minded and safety conscious drain cleaning, water jetting and industrial vacuuming company. We pride ourselves on the quality work we provide, while delivering great customer service! Call -or- click to schedule an estimate today!

"As a person in the plumbing trades both new construction and service work I have come to appreciate the skills of someone who does a craft full time and is encouraged to develop skills to make it “their” full time occupation and career. Drain cleaning is part of maintaining a plumbing system. It is a craft different than installing and repairing plumbing but it is just as important to do it correctly. The other values in McDonough’s services are several having the equipment and personnel trained and available is paramount to this no matter how big a job has gotten they have never stopped until it was completed! The other feature that is not fully understood by many is that it is always best to use someone that has only one purpose in mind and that is to get the drain cleaned and inspected and has no reason to up sell you on some repairs or replacement that you don’t need. That why we use them as a plumbing company and recommend them to our valued clients. Great company that invests in training, retaining and having the equipment that their service people need to be efficient, productive and provide the services that they are being relied on to provide."

FAQs for sewer main install, replace or repair projects in Cottage Grove, MN

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
