Follow These Steps to Prevent Home or Business Flooding
1. Avoid Building in a Flood Zone or Flood Plain
The easiest way to keep water out of your home is to avoid building or living in a flood plain. These areas are prone to flooding, flood yearly, and are generally in low areas where water accumulates frequently. If you do decide to live in a flood zone, consider a raised home and keep important outdoor structures off the ground.
2 Keep Drains and Ditches Debris Free
Avoid piling yard debris in your yard where it could flush into the sewage drains or block your ditches. Check storm drains to make sure they are clear and use a rake to remove any blockage.
3 Keep Sandbags Close
Sandbags can prevent water from entering doorways from the outside of the home. If you are in an area that commonly floods, keep these handy for emergencies. Sometimes the fire department will have them as well.
4 Maintain Downspouts and Gutters
Check and clean the gutters on your roof at least twice a year (more if you live in a heavily wooded area). Inspect your gutters for leaks or damage, as these could cause a flat roof to flood.
5 Install Drains Where Water Accumulates
If water commonly accumulates in your yard close to your home, it is a good idea to install a drain(s) in that area to prevent water from drawing close to the house. This won't stop all the water but will give it somewhere to go in the event of heavy rain.
6 Make Construction Considerations
When building or landscaping, consider if it will draw water towards or away from your home. When building a back patio, for instance, consider a slight grade away from your home to encourage water to drain away instead of towards your home.
7. Inspect Home Drains
If the sewage drains in your home do not have one-way valves, consider installing them. If flooding causes problems or backups with sewage, you do NOT want it to be knee-high in your home. One way valves can help prevent sewage back up by enabling you to shut them off.
8. Consider Water Resistant Doors and Windows
Considering Installing water resistant doors and window frames for low windows or where water is likely to accumulate. These won't prevent all water from entering your home but are a good start to keeping it out.
9. Flood Skirts and Barriers
Consider attaching flood skirts and barriers to windows and doors and air bricks. These will help to keep water out of your home.
10. Seal Openings
If water is coming in by windows, doors, or other openings, those openings can be temporarily sealed to keep water out. Metal or wooden shields that fit the openings, sealed with rubber or caulking is a good way to keep water from coming through.
