Minimizing Home Flood Damage | Extra Mile

Flooding causes billions of dollars in damage to U.S. homes every year. And floods can strike in many ways—from flash floods to hurricane storm surges to broken levees to snowmelt.

In fact, “floods are the most common and widespread of all weather-related natural disasters,” according to the National Severe Storms Laboratory.

For homeowners, the costs of cleaning up after a flood can be enormous—especially if they don’t have flood insurance. Six inches of flooding in a 2,000-square-foot home can cause nearly $40,000 worth of damage, according to estimates from FloodSmart.gov. But the total can run much higher than that depending on individual circumstances, such as the area’s real estate values, what property was actually damaged and replacement costs.

And you don’t have to live along the Mississippi river or near a coastline to experience a flood. Although most people think of flooding as river overflow, some may not realize that surface water – whether from a heavy thunderstorm, clogged storm drains or even broken water mains – can also be considered a flood, and is typically not covered in a standard homeowner’s insurance policy. Separate flood insurance, usually available through the federal government, is required to cover this exposure.

Thankfully, there are ways to help minimize the risk of flood damage to your home, if you act early enough. Here are some tips:

1. Inspect your Drainage System

Flooding can cause both exterior and interior damage to your home, and faulty water drainage is often the culprit. To rectify, begin regularly clearing your gutters of debris. Check the gutter system for any gaps or leaks that may be directing water toward the foundation of your home, rather than away from it.

Downspout extensions should divert water at least four feet away from the foundation, and the soil within 3 feet of the home should slope away from it. If you discover a slope problem, a contractor can regrade your yard to ensure water flows in the right direction.

2. Check Your Foundation and Windows

Water can seep into your home through cracks in the foundation, so inspect it and fill any cracks with the right preventive materials. Also consider sealing the outside of the foundation. Repairing large foundation cracks may require the help of a structural engineer or basement specialist.

Basement and low-level window wells are also areas that may allow water to seep into the home. Buy a window well cover that fastens securely to help prevent water from spilling into the well.

3. Prevent Sewer Backups

Sewer line backups can cause costly – and gross – flooding in homes. And whether your insurance covers it or you have to bear the brunt of the cost on your own will depend on the source of the water.

For example, if water flows into your home from overflowing storm sewers, this is generally considered a flood and some of the cost may be covered on a flood insurance policy. However, if there is a clog in your house lines and your own sewage backs up, some of the cost may be covered on your homeowner’s policy.

Thankfully, there are ways to help prevent sewage backups. One of the cheapest and most effective steps you can take is installing a backflow preventer in the main line to the sewer, which can reduce your exposure to a sewer main backup.

A professional sewer line inspection and cleaning, which usually costs less than $150, can unclog your sewer line and identify any blockages. Mature tree roots, for example, can penetrate or crush a home’s sewer line and cause a major backup into your home’s basement, so it’s important to identify such issues before they become huge problems.

Also be sure to avoid putting things down your home’s pipes that could lead to a clog or backup, such as cooking grease or large food scraps.

4. Have a Sump Pump—and Test It Regularly

A sump pump removes water that has collected in a basin on a below-ground-level area of the home, such as a basement or crawlspace. It can help prevent mold and mildew from growing, which can be an expensive consequence of water and flood damage.

Though not always an inexpensive installation, a sump pump can prevent thousands of dollars of flood damage—so it can be worth it in homes prone to flooding. Keep in mind that you may need two or three sump pumps depending on your flooding risks.

If you have a sump pump, be sure to inspect and test it regularly to ensure that it’s working properly. A common way to test it is to pour a small bucket of water into the basin to see whether your sump pump automatically kicks on to remove the water.

Remember that a sump pump only works if your home has power. So you will need a backup power source, such as a sump-pump battery or a home generator, to help ensure that water will still be pumped out of your home even if a storm or flood cuts off power to your area.

5. Move Valuables and Appliances to High Ground

Elevation is your best defense against flooding. Keep any treasured or high-value possessions above ground, such as on the upper level of your home or on the top shelves of closets and cupboards. Avoid storing objects on the floor, especially in basements or other ground-level areas.

Put any appliances, such as washing machines and dryers, on wood or cement blocks so they sit at least a foot off the ground. And be sure to make copies of all of your important documents, which you secure in a fire-safe, waterproof box kept in a high-level location. It helps to know how high floodwaters can rise in your area.

The Federal Emergency Management Agency (FEMA) offers online flood maps that identify flooding risks for a particular address.

6. Turn Off the Electricity When Flooding Seems Likely

During or after a flood, your home’s electrical system may pose a shock risk, which could seriously harm people or damage objects. To prevent such damage, first ensure that you’re not at risk for shocking yourself. Then, turn off electricity to any parts of your home that are likely to experience flooding by shutting off breakers or unscrewing fuses. And do not walk in floodwater.

“If floodwaters are getting close to the electrical entrance box, call the power supplier and have the electrical supply to the house disconnected,” advises Kenneth Hellevang, an extension engineer for North Dakota State University.

The best defense against flooding is preparation, so it’s best to take steps to prevent flood damage long before floodwaters start spilling into your home. Also make sure you’ve taken steps to help protect your loved ones, such as by putting together a flood preparation checklist and evacuation plan and making sure everyone has a copy.
