Common Causes of Basement Flooding in Richmond Hill Homes

Heavy rain and storm surcharge

Short, intense summer storms can deliver more water than storm and sanitary systems are designed to handle at once. When sewers surcharge, water can push back through basement floor drains.

Sump pump problems

Sump pumps can fail due to power outages, mechanical wear, stuck float switches or being undersized for the volume of water. A battery backup can help during storm-related outages.

Lot grading and downspouts

If soil slopes toward the house or downspouts discharge right beside the foundation, water collects against basement walls. Over time, it finds cracks and joints.

Foundation cracks and window wells

Small foundation cracks may let water in during wet periods. Window wells without proper drainage or covers can fill with water and leak through basement windows.
