Dealing with a flooded basement can be an incredibly stressful and challenging situation. When flood waters invade your basement, quick action is required to minimize damage and prevent mold growth. Here is a comprehensive guide on what to do after your basement floods.

Assess the Situation

The first step is to assess the extent of the flooding and damage.

Check where the water is coming from. Is it seeping in through cracks and crevices or rapidly rising from a broken pipe or nearby water source? Determining the source will allow you to stop any active water flow.
Estimate how much standing water there is. An inch or two of water can often be managed with towels and a wet vac. Several feet of water will require pumping and extensive drying efforts.
Look for any electrical hazards. Never step into a flooded basement if the electricity is still on. The water could be energized and electrocute you. Turn off power at the main breaker before inspecting the basement.
Check for structural damage. Has the pressure from the water compromised the foundation walls or caused cracks? Structural engineers may need to evaluate and repair major cracking.
Inspect your possessions. What furniture, storage boxes, appliances, and other belongings have been impacted? Make a list to submit to your insurance company. Anything soaked by flood waters will likely need to be thrown out.
Watch for mold. Flooding creates ideal conditions for mold growth. Look for fuzzy patches or black spots on walls and possessions. Addressing moisture and mold should be a top priority after the initial water removal.

Once you’ve evaluated the scale of the flooding, it’s time to start removing the water.

Pump Out the Water

Getting the water out is the most pressing task after a flood. The longer it sits, the more damage it will cause.

If you have a sump pump, ensure it is working properly to drain water out. Remove any debris like leaves blocking the sump pit.
Use a portable submersible pump to pump out standing water. These can pump out hundreds of gallons per minute. Place the pump in the lowest spot and run a discharge hose outside.
For minor flooding under an inch or two, you can use towels, a mop, wet/dry vacuum, or bucket brigade to remove water.
Consider hiring a professional water extraction service if flooding is extensive. They have commercial grade pumps and equipment to remove large volumes of water.
Run dehumidifiers and fans to help dry out any remaining moisture. Point them towards the wettest areas but keep them away from standing water.
Open windows if possible to improve air circulation and ventilation.

Once pumps have removed the majority of standing water, you can move onto cleanup and drying.

Dry Out the Basement

Quickly drying out the basement is crucial to prevent mold growth. Here are tips for effective drying:

Remove any wet items like furniture and boxes from the basement to prevent further water damage.
If you have drywall or wood paneling, cut out and remove any sections that got soaked. They will need to be replaced.
Use fans and dehumidifiers throughout the basement. Position them strategically around wet areas to help facilitate evaporation.
Run air movers along floors and walls. They circulate air to accelerate the drying process.
If you have dirt floors, sprinkle baking soda or calcium chloride to absorb ambient moisture.
Place absorbent materials like towels, rags, and removable carpets over concrete to wick away moisture. Replace them often.
Consider renting industrial dehumidifying and drying equipment for large scale water removal.
Keep monitoring with a humidity gauge. The relative humidity should be reduced to below 50% before rebuilding.
Look for remaining moisture or leaks and keep extracting water as needed. Drying out may take weeks after major flooding.

Persistent dampness can lead to mold outbreaks. Dehumidification and air circulation will help ward off harmful mold growth.

Clean Up the Mess

Flooding leaves behind a lot of dirt, debris, and contamination. Everything needs to be thoroughly cleaned and disinfected.

Clear out as many possessions and building materials as feasible. Dispose of anything porous like drywall, insulation and fabrics that got saturated. They are breeding grounds for mold.
Shovel out any mud or sediment left behind after waters recede. A wet/dry vacuum is helpful for cleaning concrete or floor drains.
Scrub all surfaces with disinfectant. Bleach solutions, antimicrobial cleaners and other commercial disinfectants will sanitize against bacteria and mold.
Wash any salvageable hard fixtures or solid furniture thoroughly. Mop and launder any textiles or fabrics that were exposed.
Follow your insurer’s directions for retaining flood damaged possessions as proof of loss. Take photos documenting damage for insurance claims.
Remove and replace saturated sections of porous wall materials like drywall and insulation. Metal studs can usually be cleaned, dried, and reused.
Vacuum then clean intake and outlet ducts for HVAC systems. They can harbor debris, mold spores and bacteria. Hire an HVAC contractor if systems were submerged.

Thorough cleaning removes contaminants left by flood waters and prepares surfaces for repairs or waterproofing. Be meticulous about sanitizing the basement before rebuilding anything.

Make Repairs and Rebuild

Once the basement is cleaned up and completely dry, repair work can begin.

Inspect wood framing, supports, and subflooring for signs of rot or structural damage. Consult an engineer if major issues are found.
Replace compromised sections of wood framing with pressure treated lumber.
Use moisture-proof drywall panels or closed cell foam when rebuilding walls. Avoid standard paper-faced drywall which can mold.
Apply mold-resistant paints to fully sanitize surfaces. Opt for light reflective paints that improve interior lighting.
Replace insulation with closed cell spray foam or Roxul mineral wool rather than standard fiberglass batting.
Install new flooring that can withstand moisture. Consider luxury vinyl plank, ceramic tile, or treated plywood subfloor sealed with epoxy.
Add rubber gaskets behind wall plates and anchors to prevent moisture penetration.
Seal cracks and openings along walls, floors, and the perimeter with hydraulic cement, caulking, or expanding foam sealant.

Choose flood-resistant materials when rebuilding to protect your basement from future floods. Consult a contractor about products designed for flood-prone finished basements.

Perform Waterproofing

Installing comprehensive waterproofing measures will help keep your basement dry in future floods.

Excavate along the exterior foundation walls to apply waterproof sealant and install drainage. Backfill with gravel and install perforated drain pipes.
Consider interior drainage systems for managing seepage and moisture buildup under concrete floors or behind walls. These attach to sump pumps to eject water.
Apply high quality polymer sealants like Urethane to create an impermeable barrier along foundation walls and the floor slab perimeter.
Install an interior drainage curtain system that directs seepage from wall cracks safely to the sump pit. Some systems include Mold Resistant channels.
Inject expanding polyurethane foam into fine cracks and crevices along walls and the floor slab to close up gaps.
Upgrade to a battery backup sump pump system to keep water moving during power outages. Elevate critical utilities like the furnace to minimum flood levels.
Extend downspouts at least 5 feet from the house and slope the yard for proper drainage away from your foundation.

Adequate waterproofing paired with backup power and good drainage can help minimize flooding damage and give you some peace of mind when waters start to rise.

Disinfect Against Mold

Mold poses serious health hazards and can rapidly infest porous materials left wet for over 48 hours. Here is how to clean up and prevent mold growth.

Treat any current mold outbreaks. Carefully remove or clean moldy drywall, insulation, wallpaper, fabrics and ceiling tiles. Wear protective gear to avoid spore inhalation. Consider hiring pros for large infestations.
Mix your own economical disinfecting solution. Combine 1 cup bleach per gallon of water with a dash of dish soap. Spray or scrub on all surfaces and let sit 15 minutes before rinsing.
Apply Mold Control paint which contains EPA registered biocide additives to continuously inhibit mold. Use on concrete, wood, drywall and other common materials.
Invest in a whole house humidifier connected to your HVAC system to regulate indoor moisture levels below 50%. Monitor humidity with gauges.
Routinely clean and replace filters in dehumidifiers, air purifiers, HVAC systems, and ventilation fans to improve air quality and reduce airborne mold spores.

Controlling moisture and diligently disinfecting prevents recurring mold outbreaks. Quickly treat any mold you see before it spreads through wall cavities or HVAC ductwork.

Make an Insurance Claim

Contact your insurance company promptly after a flood to start your claim.

Document damage thoroughly in writing, photos, and video before removing anything. This provides proof for claims adjusters.
Save samples or swatches of waterlogged materials like carpets and sections of drywall to demonstrate loss.
Review your policy about flood coverage and limits. Make an itemized list of all damaged possessions and building components for reimbursement.
Ask about advance or emergency payments to help begin immediate repairs.
Get multiple repair quotes and estimates for major expenses like rewiring or structural repairs.
