"They did a great job fixing our sewer line. All workers were experts of this trade. They kept all the dust concealed in the areas they had to jack hammer in the basement. They used a window well to bring in their tools and supplies. They didnâ t want to haul the mess through the house. Canâ t say enough about their excellent work. I have already told the neighborhood about their great work. Thanks guys"

"All went well with one exception. if your repair leader tells you to ask your floor people whether they or the plumbers should take up your expensive vinyl floor, do not do it! have the floor people take up your floor. the floor people can remove without damaging it and the plumber cannot. we ended up paying $5000 to replace the floor, which would not have been necessary if we had the floor people do it."

"Excellent, very professional job. Tyler repaired our bathtub fixtures and replaced the leaking main water-supply valve, as well as the defective water-pressure regulator. He did all that on time and at a reasonable price. Highly recommended."

"Great drain clearing service by Jordan without all the bait and switch add-ons provided by the lower cost services. His charge included camera work before and after, with the best guarantee: no payment if he can't clear the line. He uses more powerful equipment than the cheaper services. Don't fall for the $95 service offered by others -- I tried them and they are a scam. They come out, use their lower power equipment unsuccessfully, and then try to get you to upgrade for major repairs. This guy is honest from the start and gets your line cleared in one visit."

"Ongrade plumbing and excavating was a god send. Unbelievable how clean and professional they were from start to finish on my sewer line replacement. They did their best to protect my grass with plywood and did a very good job cleaning up given the huge pile of dirt! Thier pricing was amazing compared to some of the other estimates I received from other company's. Highly recommend to anyone for any of thier home or business plumbing issues"

FAQs for sewer main install, replace or repair projects in Longmont, CO

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.
