Where the trenchless pitch deserves pushback
Trenchless sounds expensive per foot compared to digging.
Per foot it usually is, at a published $90 to $250 against $60 to $250 for conventional replacement. That comparison leaves out the part that actually varies.
The honest number is the finished total with restoration included. Where the line runs under lawn and nothing else, digging often wins. Where it runs under a driveway, lining often wins by a wide margin.
Is a liner as good as a new pipe?
A cured liner forms a continuous, jointless pipe inside the old one, and jointless matters because roots enter at joints. In that specific sense it removes the most common failure path.
What it does not do is change the geometry. If the host pipe sags, the liner sags with it, and any grade problem you had before the work will still be there afterward.
My contractor says my line cannot be lined. Is that a sales tactic?
It might be correct, and the way to find out is to look at the footage yourself. The disqualifying conditions are visible: a collapsed section, a joint offset far enough that the liner cannot pass, or standing water showing a belly.
If the footage does not show any of those, ask for the specific reason. A clear answer names the defect and the footage distance where it appears.
Will you still have to dig in my yard?
Yes, at the access points. Both lining and bursting need an entry pit and usually an exit pit, so there is real excavation at each end of the run.
The saving is everything between them. On a long lateral under hardscape, that means two contained holes instead of a trench across the whole property.
How long does the lined pipe last?
Manufacturers publish long design lives for cured in place products. We are not going to repeat a number we cannot source to your specific installation.
What can be said plainly is that the liner removes the joints where roots enter. A lined pipe still depends on the grade and bedding of the host pipe around it.
Do I need a permit for trenchless work in Clark County?
It depends on the jurisdiction and on whether the work counts as replacing concealed piping rather than repairing a leak. County Code 22.02.195 exempts specific repairs and does not exempt everything.
For an unincorporated address the department is Clark County Building and Fire Prevention at 4701 West Russell Road. Henderson, North Las Vegas, Boulder City and the City of Las Vegas each run their own.
