Question DetailsAsked on 10/8/2013

What should the approximate cost per foot be to put in a lining for a 4" lateral sewer pipe - 65 feet long

I have a 4" clay lateral sewer pipe. It is intact so far but is 48 years old and showing its age. Tree roots are coming through and the need to have the line derooted is occurring now on a yearly basis.

Do you have the same question? Follow this Question

It depends on whether you want to hire a plumber, as is required in most areas, or have a handyman dig up and replace the 65' section. A plumber will probably be a couple thousand dollars. A handyman/laborer may be $7-800. That price could easily double if the pipe is deeper than we have around here (like in northern states). A good compromise is to have a laborer dig up the old pipe and clean the trench, then have a plumber set the new pipe. You can usually save quite a bit if everything is dug up before the plumber arrives.

You say the only problem is roots, and the joints are intact (presumably determined by camera ?). A second, alternative opinion.

Personally, I would get it routed out, then use RootX once or twice yearly - will kill the roots and keep them from growing into the sewer at a cost of $25-50/application. Does not kill the trees unless they are right over the pipe and the pipe is their primary source of foot - only kills the roots exposed to the chemical, is not a systemic poison that kills the whole plant.

Far cheaper than replacing a good pipe, especially if it is deep - Todd's estimate may work for Texas, but as he said, if you are in a northern state you can be looking at a couple of thousand $ to replace 65' of line if it is 8-10 feet down, or if trees have grown up or you have sheds or planting now lying over the line's route.
