There are two main sources of basement flooding. We will address both and provide some solutions to each.
1. Source: Basement walls and windows
- Clean out your gutters. If there are cracks in your basement walls, you will want to divert as much water as possible away from the house. Clogged gutters can result in overflow along the side of your house, and in intense downpours can cause basement flooding.
- Divert downspouts. Make sure your downspouts are dumping water at least 1.8 metres away from your home. If they are positioned any closer, you may see more water leak into your home.
2. Source: Pressure from water-logged soil below, and sewage backup
- Invest in a backflow valve. A backflow valve stops an overflowing sewage system from backing up into your home. It works by allowing sewage to flow out of your home but stopping sewage from the main line from coming back in.
- Invest in a sump pump. If all else fails, a sump pump can pump water from your basement back into the sewer system. It may be a costly initial investment, but you can expect to save some money on your insurance premiums and you can be assured your home won't be inundated with sewage.
