"This company has been our "go to" business for all of our plumbing issues for years, and just yesterday (July 16) they replaced 10 feet of our sewer line. The crew was extremely gracious, worked well as a team, and took extra care to not damage our backyard. And when the job was done, they took more time to restore our landscaping so that you can't even tell a backhoe was in our backyard! My wife and I highly recommend this company!"

We are your local go-to plumbers and HVAC guys! We can handle all of your plumbing and heating and cooling needs with one phone call! We will always give you a detailed diagnosis and clearly explain what repairs we will do. Experts by trade, competitive in the market and quality work is who we are! Call us today to schedule an appointment!

"Mile High Plumbing and Air has been game-changing for us. John and Osh have now done two jobs for us and we couldn't be more pleased. The first project was a complicated correction of poor hot water circulation to our entire home. They also replaced a leaking expansion tank and fixed a finicky shower handle as part of the first project. The second project was fixing a leak from a tankless water heater and at the same job fixing a plugged sink. They are efficient, prompt, courteous, and extraordinarily knowledgeable. We manage rental properties and, although their first work for us was for our personal properties, they are now our go-to plumbers for every property - personal and investment. Seriously grateful we found them. You will not find a better company."

Repair Sewer Line questions, answered by experts

A sewer line's lifespan runs between 50 and 100 years or more, depending on its material and local conditions. Factors that affect sewer line longevity also include how the pipe was originally installed, and whether it receives proper maintenance and cleanings to prevent clogs.

The answer may vary based on where you live. Residential sewer lines are generally buried 5 feet to 6 feet under the ground. However, it's not uncommon to see pipes buried as deep as 8 feet in colder climates in order to ensure that piping is placed below the freeze line. Digging depth could impact your sewer line replacement cost.

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.

While the answer to whether or not you need to replace your sewer line depends on your specific situation, it’s usually wise to be proactive when it comes to your plumbing. 

Unfortunately, many sewer line issues only get worse over time. However, if there’s a specific problem pertaining to your sewer line, like impinging tree roots, you may be able to put off the problem with a temporary fix.

The cost to install a two-way cleanout for a sewer line ranges from around $500 to $2,000. Two-way cleanouts provide plumbers with outside access to your sewer and can make it easier to clear out clogs and blockages.
