Flooding is a very common type of natural home disaster. There are various causes of flooding; rain, storms, tsunamis, etc. Whereas you cannot protect your home from a massive flood, you have to resort to restoring your home.
In many cases, this is an unavoidable circumstance. Cleaning up, doing repairs and restoration after flood damage is a lot of work, but it is not overly difficult.
The heaviest hit area of your home would be the basement (if you have one). This is the part of your house that would need work more than any other part.
You will first need to let some fresh air into the basement by opening up the windows or by putting a fan in the basement and turning it up to its maximum.
The electricity in the basement will no doubt have to be turned off. If it’s dark, don’t switch on the lights. Use a flashlight to see. You can use a pump to drain the stagnant water in the basement—a pump that isn’t powered by gas.
Shovel out whatever mud that has settled in the basement once you have got rid of all the water. Clean up everything that has been submerged using clean water and some detergent or bleach where you can. When everything has been cleaned up, pump out the remaining water from the basement and disinfect the entire basement.
Salvage what you can—anything that is not damaged or anything that could survive after it’s been dried up. Remove all soaked furniture and have them dried thoroughly so as to save them from mold and mildew growth. Discard any furniture that’s made of porous material since it most likely has absorbed contaminated water. When the other furniture (i.e. that made of wood, plastic, etc) has been dried, you should then clean and disinfect it.
Wet plaster, paneling and drywall should be taken out after a flood. This is because this material has most likely absorbed water (most likely contaminated) and mold and mildew will grow inside. If there is dry drywall, clean it well with detergent and clean water and disinfect it well. Check the walls’ insulation, get rid of muddied fiberglass. Only replace the insulation when the wall has completely dried up. This can take quite some time (more than a month), so you will need to be patient.
Take a look at the ceiling in case there are humidity swellings. It is also advisable to replace the insulation in the ceiling if it is damaged.
Clean up your floor as best you can. This depends on the types of floors you have. Sanitize them and let them dry up completely. You will also have to inspect the sub flooring in case the tiles need to be taken out. The entire flooring may have to be replaced if it is made of wood, as wood deals terribly with flooding.
Take care of yourself when you handle your household appliances at this time. Water can do all sorts of damage to electric appliances. These appliances could be dangerous when handled incorrectly.
Your best option, though, is to get the help of a reliable professional to help clean up and remodel your house after a disastrous flood. If you aren’t qualified, there are things you could miss or handle incorrectly.
