Cost and effectiveness of jetting Sewer pipes w/ Root X

[Amir Navabpour]

I have a rental that has had 3-4 backups.  They augered it and found signifant roots each time.  I am trying to think of the most cost effective way to deal with this to prevent fututre back ups.  I have seen quotes anywhere from 150-700 for jetting sewer pipes w/ Root X which seems like a very wide swing.  I almost wonder if there is a spectrum of services I am not aware of.   If you've done this, in your experience was this an effective treatment, to at least buy a few years?  Is there a cost effective way to deal with the root (pun intended) of this issue?
