What is sewer backup?
Sewer backup happens when the city or municipal drainage system overflows and sends water back through the pipes and into your home or office. Possible causes include heavy rainfalls, or a failure of a sump pump to deal with excess water. The water and sewage may come from a septic tank, sewer, or storm drain. Backup can cause a lot of damage, such as mold and bacteria problems. It requires an immediate clean-up by professionals specializing in sewage backup cleaning in Mississauga and Toronto.
