Often, tree roots are deep underground and unless you know the exact location of the issue, locating the roots to perform repairs can be almost impossible.
As part of our service, we offer the use of our high quality drain locator. This equipment can accurately locate drains deeper than 2m and within millimetres of the problem.
A common DIY solution is to use copper sulfate down the drains but this is not a guaranteed solution though it may buy you time.
