insulation damage during floods

Floods cause significant damage to buildings and other structures like bridges, destroy crops and result in loss of life. They affect power transmission and increase the risk of waterborne diseases such as typhoid, giardia, and cholera. They also damage the insulation of your home and reduce its quality considerably. Do you live in a heavy rainfall area or a coastal region? They are at a greater risk of getting flooded. A tropical cyclone or a tsunami in these places leads to severe water inundation. Streams and rivers can also submerge low-lying areas adjacent to them when their water level rises. Houses located in these zones tend to suffer severe structural damage during a flood.

Some of the materials used to insulate your home include fiberglass, cellulose, and spray foam. Each of them is treated differently after water damage. Some are organic and prone to mold growth while others are not when dried. If you are looking for removal or replacement of insulation in the Nepean region, visit O’Reilly Brothers Ltd.


Floodwater can weaken the foundation and walls of your house. The damage cannot be completely eliminated but mitigated with these simple strategies:

• Elevate the electrical outlets, switches and circuit breakers in your home at least 12 inches above the flood level. • Seal any cracks in the foundation and the walls. • Install check valves. They prevent the flooded drains from backing up into your house. Gate valves are preferred as they work better against pressure. • Construct barriers to stop floodwater from entering the building. • Use waterproof veneer on the exterior of your home’s walls. • Seal the windows and doorways of your house with waterproofing compounds. This prevents water from leaking in through cracks. • Grade your lawn away from your house. • Invest in battery powered sump pumps to eject water out of your basement. • Make sure there is a gap between the mulch and the siding of your house for the base to remain dry during rainstorms.

Get these renovations done and ensure proper maintenance of your property to protect it during floods.


Conditions change very quickly during floods. It’s important for you to recognize what to do to stay safe. If there is a storm forecast or if the flooding has already started, these steps can help minimize water damages.

• Make a plan and have an emergency kit ready. • Clear out the gutters and drains so water can flow freely through them. • Move your furniture and other household items to a higher level if possible. • Use sandbags to block any gaps in your building. • Shut off your electricity panel and keep a working flashlight with you. • Use a pump or a shop vacuum to remove water as quickly as possible. • Keep all your important documents in a waterproof container. • Do not walk or drive through flood waters. Stay away from bridges. • Secure fuel tanks and other heavy items which can cause damage if they are afloat. • Be prepared to evacuate and when you do, follow the directions given by the local and state authorities. Make sure you have enough money. Pack essential toiletries and batteries for mobiles.

Listen to the radio or television for information and if there is an impending flash flood, move to higher locations. Return to your home only after the authorities have indicated it to be safe.


Assessing and repairing damages is essential for homeowners hit by a flood or a storm. Look for warped walls, cracked foundation elements and holes. Make sure the water, gas, electric and sewer lines are intact. Photograph or videotape the damage caused before starting with any repairs. This serves as proof for your claim with your insurance provider.

Flood waters may carry potential toxins and contaminants like fuels and sewage. Service any damaged septic tanks, cesspools and leaching systems as soon as possible. Clean and disinfect everything in your home. Wear rubber gloves while cleaning and discarding damaged possessions.

If you stay in a region prone to flooding, then install flood compatible insulation in your home. Some of the advantages it offers are:

• It is waterproof. • Immersion does not reduce its effectiveness. • Has negligible absorbance. • Drains and dries quickly. • Is resistant to retaining silt. • Maintains its shape.

Too much moisture damages insulation and can cause severe health issues. You should remove the contaminated layer immediately.
