Top Reasons to Weatherproof Your Doors


Are you having trouble maintaining a comfortable temperature in your commercial building? Looking for a way to reduce your ludicrous energy bills? Weatherproof your doors, it may be the solution for you.

It doesn’t matter if it’s summer, winter, or anywhere in between, sealing your doors from the elements can help to prevent expensive water damage, save you money on your energy bills, and keep you and your staff members comfortable.

If you’re still not sold on the idea, here are some of the top reasons to weatherproof your doors.  

Climate Control

Do you ever remember a parent or authority figure yelling at you when you were a kid to close the door because you were letting all the cold air in? Well, Mom had a point. Doors and windows are the two major places where heat from your building can escape to the outdoors. Without a doubt, a door left open on a cold day will quickly turn the place into an icebox.

The thing that Mom might not have told you is that oftentimes even when the door is closed, it’s still allowing a lot of heat to escape. All along the perimeter of your doors are spaces that air can pass through, affecting the comfort of your office space or commercial building. That is, of course, unless you weatherproof your doors. Door sweeps, insulating felt, and weatherproofing strips can help to insulate your business, allowing you to maintain the temperature that you desire.

Protection from the Elements

Any business owner knows just how horrifying it can be to find water in their building where it shouldn’t be. Unwelcome moisture can do serious damage to floors, subfloors, and walls, and it can cause mold and mildew to grow, both of which can wind up being an extremely expensive problem to get rid of.  

Keeping your doors weatherproofed can ensure that moisture does not find its way into your building and cause expensive damage.

Save Money on Utility Bills

The more heat your doors let out, the more your heating system needs to work to maintain the temperature on the thermostat. The more your heating system needs to work to maintain the temperature on the thermostat, the higher your utility bills are going to be.

The simple solution to this problem is to weatherproof your doors so that they more effectively trap heat inside, taking the burden off of your heating system. Weatherproofing costs and effort are worthwhile, saving money and reducing stress from high energy bills.

How Do I Know If My Doors Need Weatherproofing?

To ensure energy efficiency and weatherproofing, inspect doors for leaks and drafts. Check the perimeter of your doors to see if you can see light coming through from the other side. If you see any light, your door is most likely in need of weatherization.

How Do I Weatherproof My Doors?

If you’re looking to weatherproof your doors, check out this guide or consider using any of these products:

Adhesive Weather Stripping

Using adhesive weather stripping around your door fills gaps to prevent heat loss and cold air entry.

Door Sweep

Door sweeps seal the door bottom, allowing easy opening and closing. These seals are vital for preventing rainwater from seeping in.


There are two popular types of door insulation:  Felt and plastic film. They seal gaps and retain heat like adhesive weather stripping but are for lining doors.

Door Replacement

Some doors are too old to effectively weatherproof. If that’s the case with your doors, consider replacing them with more energy-efficient ones.
