Basement flooding, you never expect it and you can't really prepare for it. Unexpected issues happen all the time in homes, but a basement flood is not only unexpected, it can also be very dangerous.
Turn It Off
The absolute first thing that you need to do when your basement floods is to shut off any power and gas into the basement. The importance of this can not be stated strongly enough. If you do not know where your shutoffs are call an electrician before entering the basement.
Wear Protective Gear
Once you are sure the water is safe from electrical or gas dangers, you should still put on protective gear before entering the water. Wearing gloves and boots or waders is advised. The water you are walking in is likely going to be grey water but could easily be black water, depending on the source. Until you are sure what type of flooding you are dealing with, take all precautions.
Stop The Water, Fast
It is important that you identify the location of where the water is entering your home as soon as you are able. If the water is entering from a broken pipe, shut off the water. Check your drains as well to ensure they are unclogged. Determine the extent of damage to your basement with the knowledge that time is against you in the cleanup process. If the water is greywater and not black water you will have 48 hours to remove the water as well as clean and dry everything. If you are unable to do this, you need to seek out the help of a professional cleaning service for the safety of your home and family.
Clean Or Have It Cleaned
If it something you can clean yourself, read our steps on this other post. If not, look to the next paragraph.
A professional team will arrive on scene and begin removing all standing water from your home. Any and all water damaged items and furniture will be removed and dried off entirely. If the basement is carpeted, it will likely need to be removed as it can prove difficult to dry and any moisture that it could hold can promote mold growth. Additionally any wet drywall will likely need to be replaced. Often with flooding, dirt will infiltrate the basement and any contaminated dirt will need to be removed from your basement and crawlspaces.
In any case of serious flooding we strongly suggest calling in a professional team of experts to restore your home to the its pre-flood condition of safety, comfort, and appearance. Time is not your friend in a flood situation and after the first 48 hours when the water becomes black, a whole host of mold and bacteria begin to settle on the flood site. If not properly cleaned, this can become issues that can hurt your family's health for years to come.
