Sewer back-ups create odor, property damage or loss, the possibility for mold or mildew, and increased risk of disease. The restoration of your home can be costly and insurance claims can prolong the difficulties being endured with a sewer back-up.
Sewer back-ups caused by many reasons, such as:
Man-made blockages! Most often grease build-up, rags, clothing, and toys.
Tree roots! Tree roots can extend for several meters below and around a tree and wrap themselves around a pipe which causes collapse. Also, they find their way through cracks and joints seeking moisture and completely blocking the pipes.
Sagging! A section of the pipe may drop below proper grade as a result, the flow will be deterred.
Cracks! Age or ground movement can cause cracks in the pipes which results in a blockage.
