Water damage is now the leading cause of property damage in Canada. Steps you can take to reduce the risks:
#1: install a sewer backwater valve to prevent backflow of sewage in to the house and free flow of air and outflow of sewage.
#2: locate laundry room in the basement
#3: extend downpipes away from the home
#4: slope lot so it drains water away from the foundation
#5: install rain water barrels to collect water run- off
