"The company was very fast, efficient, and very professional. I had to have my sewer pipe replaced, so they had to dig up my laundry room and bedroom floor. About a 1’1/2” wide of concrete floor They fixed the pipe and repaired the cement floor and cleaned up all of there mess. The workers were very nice and did a great job. And very far price. I’m very happy with their work. Would highly recommend this company."

"He was very knowledgeable and explained to me why it would be best to replace my 15 year old water than to repair it. But I was not pressured either way. I decided to replace, and it was a great investment."

"When my sewer line backed up and couldn't be fixed due to its age (installed in 1942), I made enquiries and chose the company that was most highly rated and with a reasonable cost. Jake came out and explained everything to me. He obviously knew what he was talking about. He came and had the work done efficiently and well and on-time and I am very satisfied with the company and with Jake's service."

FAQs for sewer main install, replace or repair projects in Denver, 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.
