If left undisturbed, roots will slowly but surely fill the inner sections of the pipe and cause a blockage. Furthermore roots will clog up household fats which pass through the waste water pipe and cause them to accumulate for long enough to cause a blockage. The first sign of trouble comes in the form of slow draining times in your sink and toilets. Toilets often make a strange noise causing quite a bit of concern for whoever lives in the house or flat! In time, the pressure from root intrusion will become so great that the entire pipe will collapse.
If this is the case our engineers will be required to perform an entire drain excavation and replacement, usually at considerable cost to the homeowner. Regular drain inspections and drain cleaning will prevent this scenario. Early detection of root intrusion usually means our engineer can rectify the matter, or in the worst case scenario you may require sewer relining, a measure which is far less costly and less invasive than drain excavation.
