All Your Questions Regarding Flood Vents, Answered!
Jul 03, 2019

Despite flooding being a frequent occurrence in several regions of the United States that can lead to costly damages and repairs, a lot of buildings and homes are still lagging behind when it comes to installing flood vents. This blog answer the most frequently asked questions about these tools and put your skepticism to rest.

What Is A Flood Vent?

Also known as a flood port, a flood vent is an opening in one or more sides of a wall that allows water to flow unobstructed in and out of the building. This device is meant to lower the probability of structural damage caused by stormwater or flooding, especially for buildings that are situated in flood plains (i.e. flood hazard areas).

Flood vents can be used in crawl spaces and basements. They’re available in forms of solid hinged covers as well as vented hinged covers, and may also be used as foundation vents.

How Are Non-Engineered And Engineered Vents Different?

Flood vents come in both engineered and non-engineered forms.

Engineered flood vents, like the ones we have at Crawl Space Door Store, are designed by registered architects and engineers, and are certified by them. They meet all the performance characteristics approved and listed by FEMA.  

Non-engineered flood vents are assessed by simply calculating the existing openings in the vent itself. For them to be FEMA compliant, they must suit the requirements of 1 square inch of free space for every square foot of the enclosed area.  

Who Needs Flood Vents?

According to the National Flood Insurance Program (NFIP), flood vents are required for residential as well as commercial crawl spaces, basements, garages, and other similar enclosed structures located below the Base Flood Elevation (BFE) which refers to the height of the base flood. This requirement is necessary for areas that lie under the category of “Special Flood Hazard Areas”.  

Building and property owners are expected to comply by the NFIP for the security and safety of their buildings.


Why Should You Have Flood Vents?

As discussed above, buildings located in certain areas are obligated to have flood vents installed for safety purposes. In addition to this, having flood vents also gives you flood insurance, which opens several other doors. For instance, you can’t get a mortgage in some areas unless you have flood insurance for your home.

Flood vents protect the structural framework of your house, preventing the windows and doors from “blowing out” because of water pressure in case of flooding. They also help maintain the stability of your foundation, and keep your house standing tall.
