Denver homeowners own the sewer line from the house to the city main, and many of those lines are old clay or cast iron pipe that tree roots love. Sewer repairs are some of the most expensive plumbing jobs a homeowner faces, which is why camera inspections and trenchless methods matter so much here.
The companies below repair and replace sewer lines across the metro. Several specialize in trenchless pipe lining or pipe bursting, which can avoid digging up a whole yard or driveway.

Never agree to a sewer replacement without seeing the video. A good company will walk you through where the break, belly or root intrusion is.
Pipe lining and pipe bursting avoid most digging, but they do not suit every line. Ask why a method was chosen and what the warranty covers.
Work that ties into the city main needs permits and sometimes street work. Confirm the contractor pulls them and restores the right of way.
