A minor basement flood can be inconvenient and concerning, but it is usually manageable if you take the right steps. With some preparation and quick action when water intrudes, you can handle the situation effectively. This guide covers what to do before, during and after a minor basement flooding event.

Ensure You’re Prepared

If you know your basement is prone to flooding, you can prepare by doing the following:

Check Your Sump Pump
The sump pump, especially if equipped with reliable macerator pumps, acts as a primary defence against basement flooding. Make sure it is plugged in, turned on and functioning properly to automatically remove groundwater before it floods your basement. Test it regularly and replace the pump every 3-5 years. It's also worth looking into pumping stations as these can be used to collect and drain rainwater and drain it to the sewage system automatically if required.

Clear Floor Drains
Clogged floor drains can quickly overwhelm your sump pump. Make sure any basement floor drains are cleaned out and free of debris so water can flow freely. Consider installing mesh drain covers to keep out leaves, toys and other objects.

Have an Emergency Plan
Prepare emergency supplies like towels, a wet/dry vacuum, mops and buckets so you can respond quickly. Know where to turn off electricity if needed. And know how to contact emergency services if sewage backs up.

During a Flood

If you’ve noticed your basement flooding, these are the steps to take:

Identify and Address the Source
Try to locate where the water is entering from. It could be groundwater seeping in through cracks and holes, overflowing from a blocked drain or leaky appliance, etc. Address the source immediately if possible to limit flooding.

Remove Items from Flooded Areas
If water begins pooling in your basement, carefully move boxes, furniture, rugs, and other belongings out of flooded areas to prevent damage. Only remove items if you can do so safely and without entering standing water.

Run a Wet Vacuum
Use a wet/dry vacuum to remove pooled water. Make sure any outlets have been turned off before working with electronics. Don’t vacuum up sewage water - call professionals instead. Vacuum up as much as possible to drain the area.

After a Flood

Once you’ve removed all of the water from your basement, it’s time to do the following:

Prevent Mould Growth
Remove wet, porous items that may develop mould like carpet, drywall and insulation. Use fans, dehumidifiers and open doors/windows to fully dry the basement. Disinfect any areas contaminated by sewage backup.

Make Repairs
Once the basement is fully dried out, make repairs to seal any cracks or holes where water entered. Consider re-grading soil outside or extending downspouts further from your home’s foundation to direct groundwater away.

File an Insurance Claim
Contact your home insurance to see if your policy covers pump repairs, flood cleanup, drain unclogging and related costs. Many minor basement floods qualify for coverage.

Staying prepared is key when it comes to minimising basement flood damage. By keeping your sump pump maintained, quickly addressing leaks and having an emergency plan, you can handle occasional minor flooding incidents. Take action at the first sign of water intrusion to protect your basement.
