Water is essential for many different things, but it’s certainly not your friend when it enters your home unexpectedly! Flood barriers for doors can provide homeowners protection against rising flood waters in the event of a storm or overflow from nearby bodies of water. Your home is most likely one of your most valued assets so if approaching storms or flash flood warnings send you into panic-mode you want to protect the interior as much as possible.

Did you know floods are one of the most common and costly natural disasters? Unlike other natural disasters, repairs and cleanup following a flood have long-term consequences for homeowners. Repairing water damage can cost you a substantial amount of money. Even as much as an inch of water inside your home can be detrimental. Flooding frequently occurs as a result from hurricanes, several days of sustained rain, or thawing snow. A flash flood happens suddenly often resulting from fast rising water along a stream, river, or low-lying area.

Based on current data reported from the National Centers for Environmental Information (NCEI) natural disasters have accounted for millions of dollars in damage in the U.S. In 2020 the record for tropical storms was broken from the previous year with 30 named tropical storms. Billion-dollar inland flooding events have increased significantly over the past few years. The reason behind these flooding events have resulted from heavy rainfall due to changes in climate. Warmer temperatures have prompted the atmosphere to retain higher water vapor leading to an increased potential for extreme heavy rainfalls.

How to Prepare for Flooding

If you live in a low-lying area or your home is in a flood zone, making necessary preparations will help you avoid permanent water damage to your home and valuables. Consider making renovations by elevating or reinforcing your home if you live in a floodplain to minimize the effects from water damage.

  • Hire an electrician or professional to move electrical outlets and wiring to one-foot above flood level.
  • If you have a basement use a sealing product to waterproof walls and points of entry.
  • Install a sump pump for removing standing water and keep a battery-powered backup.
  • Hire a plumber to make necessary installations for back-up or backflow valves if not currently in place. This will prevent floodwater from entering your home in the worst imaginable way.
  • Seal up cracks or gaps in your foundation to prevent water from seeping in. An inexpensive mortar or masonry caulk will provide temporary protection, however, you will need a more permanent fix if seeping water is a continuous problem in your home.
  • Install a flood sensor in areas that may be prone to flooding in high-water situations such as basements. Many security systems offer these with their systems as an added measure of protection. Flood sensors can detect and alert you to leaks before significant water damage occurs.

Clear out drains, gutters, and downspouts. If the weather forecast is predicting heavy storms or rainfall with the chance for flooding, overflow from these can lead to more damage to your home. Remove debris from gutters and drains to help the water flow out and away from your home.

Hurricane Prep

Have an evacuation plan in place in the event of a natural disaster or emergency. Approaching storms such as hurricanes and tropical storms can bring dangerous storm surges that no amount of preparation can prevent. Stay tuned into weather alerts and updates from local authorities on flooding and flash flood warnings that warrant mandatory evacuation.

To help protect your home and valuables here are some steps you can take :

Gather outside items that could be blown away from strong winds or swept off in a flood such as lawn furniture, bicycles, outside toys, gardening tools, and equipment. Store anything and everything you can indoors, in the garage, or in a shed. If you can’t store them inside, secure them by anchoring them down to something solid and sturdy such as a large tree or building.

In case of power surges, cut off your propane tank if your home has one. Cut off gas, electricity, and water before evacuating your home or if you see downed power lines. Unplug appliances and elevate above flood levels if possible.

If flooding conditions do not warrant an emergency evacuation and you are planning on staying home, consider filling up bathtubs and sinks with tap water. Sometimes water services may go out or become contaminated from floodwater so it’s a good idea to plan ahead to have clean water for use in case this occurs.

When planning for evacuation the Federal Emergency Management Agency (FEMA) suggests the ‘Five 5 P’s of Evacuation’ on things to take with you: People, Prescriptions, Paper (important documents), Personal Needs, and Priceless items.

Construct barriers to prevent floodwater from entering buildings or your home by using sandbags, building flood-walls, or purchasing a doorway water barrier.

Sand Bags

Oftentimes communities will offer residents free sandbags in preparation for an approaching storm or when flooding is expected. These offer some protection against flooding when used appropriately. The use of sandbags is mainly to divert moving water as well as debris to minimize water damage. There are different ways that you can use them for a multitude of reasons, but if not stacked appropriately they won’t serve their purpose effectively.

Sand is the most appropriate material to fill your bags with as it provides a dense barrier to block water molecules from getting through. If sand is not readily available soil or a similar dense substance will work as well. Fill your sandbags just slightly more than half-full, but not all the way. Bags are much easier to handle if they are no more than 40 pounds when filled, although this may vary depending on the size of the bag. Various sand bag sizes are available, but typical bags for sand-filling are 24-26 inches long by 14 inches wide. Bags will also be  easier to shape and form to create an effective wall against flood waters when they are not filled completely.

When you are creating a sandbag barrier, it is best to keep it to just two layers. The exception to this would be if you were planning to create a pyramid barrier. The barrier should be slightly wider at the base than height to give it more stability. Complete one layer at a time and tamp down each bag into place  You can do this by stepping on top of each bag to compact it. The tighter the bags are packed together, the less chance of water seeping through. As you place the bags for the next layer, keep staggering the seams as you would if you were laying down bricks.

To protect buildings from water getting in where the water levels are expected to rise you would stack the sandbags against the building. For sliding glass doors, windows, vents or other entries you can create a seal to prevent water intrusion by placing a plastic sheet (such as visqueen or plastic lining) on the ground and up against the wall then stack the sandbags on top. If you will be creating a barrier around buildings be sure to allow a path for the water and debris to flow between the buildings.

Sandbags offer a temporary fix, but they can be heavy to move and they are not long-lasting after enduring a flood. It’s also important to remember these are designed to significantly reduce the amount of water that seeps in, but do not create a water-tight seal. Flood barriers for doors can provide more security than sandbags and are easy to store and reuse.

Flood Barriers for Doors

A doorway water barrier offers superior flood protection over sandbags as they are designed to withstand the weight against moving water and long-lasting. These devices are also much easier to maneuver, install, and allow you to maintain access to your entryway if needed while in place. Flood barriers can also be adjusted to provide a custom fit creating a water-tight seal. They are the more expensive choice in water-retaining solutions; however, these will last you much longer over time and offer better versatility over alternative options.

Factors such as exposure to UV light, humidity, extreme temperatures, and continuous contact with flood water are all factors that can deteriorate sandbags making them less effective over time. Flood barriers are easy to remove and will maintain their protective properties when stored properly. A doorway water barrier is the only option that offers a completely water-tight anti-flood solution with no gaps, holes or hinges to allow water through.

Flood Insurance: Do You Need It? Is it worth the cost?

Depending on where you live, you may need or be advised to purchase flooding insurance if you live in a flood zone. Many mortgage lenders will require it per their policy when purchasing a home that is in a flood plain. Many homeowners are shocked to learn their homeowner’s insurance doesn’t cover flood protection after experiencing water damage.

Flood insurance isn’t required if your home is not located in a flood plain; however, if you live in an area that is high-risk for natural disasters or potential flooding it might be a good idea to have.

According to the Federal Emergency Management Agency, the cost of a flood insurance policy averages around $700 a year. Costs will vary greatly based on the location of your home. Depending on the elevation, costs can increase to as much as $2,000 or greater – something to consider before buying a new home.

Some key questions to ask yourself if you are considering whether purchasing flood insurance is worth it should be:

  • Has your property ever experienced flooding before?
  • Are you located near a flood plain?
  • Does your home have a basement?
  • Can you afford coverage for flood insurance?
  • Can you afford repair costs from flood damage without flood insurance protection?

Another factor to keep in mind when purchasing flood insurance is coverage amounts. Consider the costs incurred from water damage. Policies will cover up to the value of your home, but National Flood Insurance Programs put a cap on limits to $250,000. This means if the value of your home exceeds this limit, you may be looking at paying any remaining costs out of pocket. Private flood insurance providers may offer higher limits.

There is typically a 30-day waiting period from the purchase date for flood insurance to go into effect with a couple of exceptions. The reason for this is to deter fraud. Insurance providers aim to deter people from purchasing a policy at the threat of an approaching storm in order to collect a claim and drop the policy afterward.

While the costs of coverage might seem steep, especially for that waterfront property you desire, it can be a huge benefit in the event of a flooding situation. If you have a commercial property installing flood-proof systems such as flood barriers for doors may help to bring your rates down to save money on flood insurance.
