The private sewer lateral running from your house to the city main is your responsibility in Denver, and repairing it is one of the larger plumbing expenses a homeowner faces. The price is driven less by the defect itself than by what sits between the crew and the pipe.
What sets the price
- Depth of the line. Deeper means more excavation, shoring for safety, and longer hours.
- Length of the run. Alley connections are short. Front yard runs to a street main are not.
- What is on top. Lawn is cheap to restore. Driveways, sidewalks, mature trees, and finished basement slabs are not.
- Pipe material and condition. Clay, cast iron, and Orangeburg each behave differently under repair.
- Method. Spot repair, full open trench replacement, pipe bursting, and cured in place lining are four different price tiers.
- Permits and inspection, which are required and non negotiable.
- Traffic control and right of way requirements when the work reaches the street.
Spot repair versus full replacement
A spot repair makes sense when the camera shows one clearly defined defect in an otherwise sound line. A single crushed section under a driveway, one offset joint, or one root intrusion point are all good candidates. Full replacement makes sense when the pipe is Orangeburg, when cast iron has lost its bottom channel across long stretches, when there are multiple failures along the run, or when the line has a belly that needs regrading. Paying for three spot repairs over five years costs more than one replacement.
Why Denver laterals fail
Older neighborhoods across the metro were built with vitrified clay, and clay is jointed every few feet. Tree roots exploit those joints. Expansive Front Range soil swells and shrinks with moisture, which pulls joints apart and creates sags. Cast iron corrodes from the inside out. Orangeburg, used in some mid century construction, is a bituminous fiber pipe that deforms into an oval and eventually collapses. All four are common and all four are fixable.
How to compare bids
- Confirm every bid is for the same scope and the same method.
- Ask what restoration is included. Sod, concrete, sprinkler repair, and flooring are frequently excluded.
- Ask who pulls the permit and whether inspection is in the price.
- Ask what happens if the crew hits an unexpected condition. Get the change order policy in writing.
- Get the warranty term on both pipe and labor.
