How to prevent basement flooding

Toronto has experienced significant rainfall this summer, leading to numerous instances of basement flooding. At Woodsmith Construction Inc., we understand the importance of protecting your home from water damage, especially given the high costs and health risks associated with flooded basements. Here’s a detailed guide tailored to our clientele on how to effectively prevent basement flooding in Toronto.

Understanding the Causes of Basement Flooding

Basement flooding can result from several factors:

• Heavy Rainfall: Overloaded sewer systems can lead to backups.
• Groundwater Seepage: Water enters through cracks in the foundation.
• Poor Lot Grading: Improper drainage directs water toward the house.
• Failed Sump Pumps: Malfunctioning pumps fail to remove collected water.
• Blocked Eavestroughs and Downspouts: Clogged gutters cause water to overflow.

Effective Strategies to Prevent Basement Flooding

1. Regular Maintenance of Gutters and Downspouts

   • Ensure that your eavestroughs and downspouts are clean and free from debris. This prevents overflow and directs water away from your foundation.
   • Extend downspouts to discharge water at least two meters from the foundation.

2. Proper Lot Grading

   • Grade the soil around your home to slope away from the foundation. This helps direct rainwater away from the house.
   • Implement swales or rain gardens to manage and absorb excess water.

3. Installation of Sump Pumps

   • Sump pumps are crucial for removing water that accumulates in the basement. Ensure your sump pump is appropriately sized and maintained.
   • Consider a battery backup system to ensure functionality during power outages. The City of Toronto offers a subsidy of up to $1,750 for sump pump installations and backup systems.

4. Backwater Valves

   • Install backwater valves on your sewer line to prevent sewage from backing up into your home during heavy rains. This device is essential for protecting your basement from contaminated water.
   • The City provides a subsidy of up to $1,250 for backwater valve installations.

5. Foundation and Wall Sealing

   • Seal cracks in your foundation walls and floors to prevent water ingress. Apply waterproof coatings and sealants for additional protection.
   • Ensure that basement windows and doors are properly sealed and consider window well covers to keep out water.

6. Downspout Disconnection

   • Disconnect downspouts from the city’s sewer system where feasible. This helps reduce the burden on the municipal sewer system and minimizes the risk of backups. The City of Toronto mandates downspout disconnections in certain areas and provides guidance on proper procedures.

Utilizing City Programs and Subsidies

The City of Toronto has implemented several programs to help homeowners protect their properties from basement flooding:

• Basement Flooding Protection Program: This multi-year initiative aims to upgrade the city’s sewer infrastructure and overland drainage routes. Homeowners can check the status of projects in their area through an interactive map provided by the city.
• Basement Flooding Protection Subsidy Program: Homeowners can receive financial assistance for installing flood protection devices. This program offers subsidies for sump pumps, backwater valves, and severance of storm sewer connections, totalling up to $3,400 per property.

Additional Tips and Emergency Preparedness

• Regular Inspections: Have a licensed plumber inspect your drainage system and basement plumbing regularly to identify potential issues before they become major problems.
• Emergency Kits: Prepare a flood emergency kit that includes essential items like food, water, medications, and important documents. This kit can be crucial during a flood emergency.
• Flood Sensors: Install flood sensors in your basement to detect water early and take prompt action to mitigate damage.
• Insurance: Ensure you have appropriate flood insurance coverage, as standard homeowner policies often do not cover flood damage. Review local and federal programs for additional assistance.
