Can A Storefront Door Sweep Really Keep Rain Out?

One of the most common questions when buying a storefront door sweep is can it really keep rain out. The short answer is Yes. There are a couple of factors to this. In this article we explore how to keep rain out of your building by purchasing a storefront door sweep.

Is The Commercial Storefront Door Located At A Low Grade

Chances are if you are reading this article, you are getting water inside of your building. Does water pool up in the area where your door is located? If a storefront door is located at a lower part of the ground rather than a higher grade, then water will always pool up at the base of the door each time it rains. If this is the case, a door sweep will not help. Properly grading the ground outside of your building, installing gutters to divert water, and other construction measures will need to be addressed with your building contractor.

Does Your Storefront Door Have A Threshold

All exterior storefront doors should have a threshold. If your door has a properly installed threshold, this will greatly aid the storefront door sweep from preventing rain from getting in your building. Keep in mind ADA thresholds are typically a 1/4 inch in height. If it rains and you notice that water comes into the building from beneath the door threshold, then your door threshold has not bee installed properly. You will need to remove the door threshold and apply heavy caulking all the way across the bottom of the threshold plate. A door sweep will not keep rain out if the door sweep is not properly caulked to keep rain from coming in through the bottom of the threshold.


Vinyl Storefront Door Sweeps Prevent Rain From Getting In Your Building

Assuming your storefront door is at a normal grade surface and you have a properly caulked ADA door threshold, then a storefront door sweep will keep the rain out. With that being said since rain and moisture is of prime concern, the best storefront door sweep to keep rain out is a combination vinyl door sweep with rain drip. The combination vinyl rain drip storefront door sweep should be installed on the bottom rail of the storefront door. The vinyl should be touching the ADA threshold to create a solid seal. When it rains, any rain that hits the door will drip down and be diverted by the door sweep's rain drip.



Add An Overhead Mounted Rain Drip

It is also recommended to add an overhead rain drip to your storefront door. This rain drip projects much further than the combination door sweep's rain drip. This will help divert rain from pooling up near the door threshold.
