Sewer Line Repair for Older Clay Lines in Boulder, CO

Many Boulder homes sit on sewer lines that are 60 years old or older. When one of those lines fails, the repair is the homeowner’s responsibility, which is why sewer line repair in Boulder should start with a clear look inside the pipe. Go Direct Services is a family-owned sewer and water line contractor. We serve Boulder neighborhoods including University Hill, Mapleton Hill, Whittier, Martin Acres and Table Mesa, along with Louisville, Lafayette and Superior.

Who is responsible for sewer line repair in Boulder?

The City of Boulder says homeowners are responsible for their sewer service all the way to the city main. That covers the whole run of pipe from the house out to the main.

It’s a good reason to know your line’s condition before it fails. A camera inspection is the first step, because it shows where a problem sits along that run and how serious it is.

Clay pipe and big trees: why Boulder sewer lines back up

University Hill, Mapleton Hill and central Boulder often have original clay sewer pipe. Clay was laid in short sections, with a joint every few feet. Each joint is a weak point.

Boulder’s big old trees make that worse. Roots push into the joints looking for water, then keep growing inside the pipe. They snag paper and waste, and as they thicken they can crack the clay.

Cleaning clears the roots for a while. If they are coming in at several joints, they grow back, and the pipe keeps weakening.

Signs of roots or a failing sewer line in a Boulder home

• Slow drains throughout the house, often worse after heavy water use
• A backup in the basement floor drain, sometimes on laundry day
• Clogs that return on a regular cycle after cleaning
• Gurgling toilets or a sewage smell in the basement
• A sunken or soggy spot, or extra-green grass, along the line’s path
• For the water line: low pressure, rusty water or an unexplained jump in the bill

A clog that comes back on a schedule is the classic root pattern. It usually means the cause is in the pipe, not in what’s going down the drain.

Camera first: repair, replace or just clean?

Our sewer camera inspection is $99. We record the line from an access point out to the main and show you every root, crack and joint we find.

• Light roots, pipe intact: drain cleaning ($280) or hydro jetting (about $1,000). This buys time, but it doesn’t seal the joints.
• Damage in one section: a spot repair replaces that piece, often with a new clean-out for easier access later.
• Clay cracked or root-filled along its length: full replacement. On a clay line that has been in the ground for decades, this is often the more sensible spend.

We’ll tell you plainly when a repair would be a patch on a line that is failing everywhere else.

Is pipe bursting a fit under Boulder’s mature trees and landscaping?

Open trenching through an established yard can disturb landscaping, walkways and the roots of trees you want to keep. Pipe bursting replaces the sewer line from two small pits instead. A bursting head breaks the old clay apart as it is pulled through, and new seamless pipe follows right behind it.

Clay is brittle, so it breaks apart readily during bursting. The line does need to run fairly straight, and a collapsed or badly misaligned section may need to be dug. We’ll tell you which applies after the camera inspection.

We do not do pipe lining. Learn how trenchless pipe bursting works.

Water line repair for Boulder homes

Your water service line carries water from the street into the house. In older homes it may be galvanized steel, which rusts from the inside and narrows, or older copper that can develop pinhole leaks.

When a leak is hidden, we do exploratory leak excavation to find it. If the line is aging out, replacing it is usually smarter than chasing one leak after another. We confirm the right utility and permit for your address before work starts.
