What Our Customers Are Saying

Common Sewer Line Problems in Denver
Many things can go wrong with a sewer line. These are the problems our Denver sewer repair technicians see most often:
- Blockages: Debris, grease, or foreign objects get stuck and cause slow drains or backups.
- Leaks and cracks: Lines crack over time, which can cause water damage and contaminate the groundwater. Denver’s freeze-thaw cycles put added stress on aging joints.
- Tree roots: Mature trees in older neighborhoods send roots into sewer lines looking for water, causing blockages and damage.
- Corrosion and rust: Older metal lines, like cast iron, rust and can fail structurally.
- Shifting ground and poor installation: Soil movement or a bad installation job can pull a line out of alignment.
Many Denver homes still have the original cast iron, clay, or Orangeburg sewer lines, and those older materials are more prone to these problems.

Our Denver Sewer Repair Methods
We choose the repair method based on what the camera shows and what fits your budget:
- Trenchless pipe lining: A new lining is installed inside your existing pipe, repairing cracks and leaks with little to no digging. It can be an option when the pipe is damaged but still intact.
- Spot repair: If damage is limited to one section, we repair or replace just that section. Excavation is limited to the damaged area, so more of your landscaping stays intact.
- Traditional excavation: When the damage or the pipe’s condition calls for it, we dig down to the line and repair it directly.
Which method fits depends on the condition of your pipe. We’ll explain your options and give you an upfront quote before we start. If the damage runs the length of your line, we’ll tell you, and you can learn about sewer line replacement, including trenchless options.
Sewer Repair vs. Sewer Replacement in Denver
Sewer line repair is often the most cost-effective approach when the problem is isolated to one area rather than the whole length of the line. It also limits excavation, so you keep more of your landscaping.
When the camera shows widespread damage, repeated failures, or a pipe that’s too deteriorated to repair, replacement is the better long-term choice. We’ll always tell you which one we recommend and why, and we’ll give you an honest second opinion if you’ve already been quoted elsewhere. Learn more about sewer line replacement.

Denver Sewer Repair FAQs
Warning signs include sewage backing up into drains, multiple slow or clogged drains, gurgling pipes, sewer odors, soggy or unusually green patches in your yard, and cracks in your foundation. A camera inspection confirms what’s wrong.
It depends on the damage. If the problem is limited to one section, repair is often enough. If the line is damaged along most of its length, replacement may be the better choice. We’ll show you what the camera finds and recommend the right option. See sewer line replacement.
Trenchless repair fixes your sewer line with little or no digging. One common method is pipe lining, where a new lining is installed inside the existing pipe. It can be an option when the pipe is damaged but still intact.
