How to Reinforce Your Home to Resist Flood Damage


Consider these ways to reinforce your home during storms.

Along the South Coast of Massachusetts and Rhode Island, there is a high potential for flooding as a result of increasingly violent storms. High winds, downbursts, and fast-moving water are just a few examples of forces that increase the risk of water damage inside your home. Even with our close proximity to the water along the coast, most people don’t realize that flood insurance is not covered in your a homeowners insurance policy.

Caulking and Weather-Stripping

You may know that weatherizing can keep your home warmer while saving you money on energy bills. But did you know that quality caulking and weather-stripping can also help protect your home from flood related water damage?

Checking for existing leaks and sealing cracks is an effective way to minimize flood damage. Before applying caulk or weather-stripping, assess your home to figure out where water may enter during periods of heavy rain and wind. Look for gaps or holes around window frames, doors, and vents. Pay special attention to cracks in your basement, roof, or in the foundation of your home. Keep in mind that for large cracks, you may need to call a professional.

Affixing weather stripping to all doors that provide outside access is another way to keep water, snow, or sleet out of your house. When installed correctly, weather-stripping should create a watertight seal when doors are closed. Both caulking and weather-stripping wear with time and use, so make sure to inspect both annually.

Gutters and Downspout Inspection

It is important to keep your gutters and downspouts clear all year round. If leaves or other debris are clogging gutters, they can create blockages that prevent water from flowing away from your home. Make sure to also check for leaks in your gutters and downspouts to avoid potentially ruining both the siding and foundation of your home.

Especially during times of heavy rain, it is crucial to ensure that water is moving away from the foundation of your home to avoid flooding. If this is a problem for your house, consider purchasing a downspout extender. Ideally, water should be released away from your home at a distance of at least five feet.

Check Flood Vents

In the event that water does enter your home, flood vents can reduce the likelihood of structural damage by equalizing water pressure inside and outside of your home. If you have structures that are below base flood elevation or if you live in an area prone to flooding, you should consider installing flood vents. It is important to note that while many crawlspaces have air vents in the foundation, these do not function in the same way as a flood vent.

Make sure you have enough flood vents for the size of the area you are trying to vent. Vent opening should be large enough to provide for the force and flow of water. They should also be located low enough on the structure of your home to avoid draining water back to your foundation. Lastly, make sure to check regularly that flood vents are not blocked by debris, especially during periods of heavy rain and flooding.

Dry vs Wet Flood-Proofing

Dry flood-proofing involves several methods for keeping water from entering your home all together, while wet flood-proofing has more to do with minimizing damage once water has gotten into your home. Often times, these approaches are better suited for homes or structures that are not being lived in during times of flooding, such as vacation or seasonal homes.

For dry flood-proofing, you should consider steps such as anchoring your structure, reinforcing walls, raising all utility services above flood walls, and installing a sump pump in your basement. Wet flood-proofing consists of changing the uninhabited areas of your home that are more prone to flooding, such as basements and crawlspaces. This can include installing flood vents (described above) or replacing all construction and finishing materials with flood resistant materials.

Often times, a structural engineer is required for when implementing either of these methods. Make sure to be aware of permitting and coding regulations in your specific area before making large structural changes to your home.
