4 Easy Methods to Weatherproof Your Door

Temperature changes may impact any section of the house, and one of the components that might contribute to this issue is the external door. Weatherproofing the door might help to keep your internal area from being too chilly. Bugs and bad weather are common throughout certain seasons of the year, thus, knowing how to weatherproof a door to keep the cold or warm air out of your home can help you to save money on power and overall house maintenance.


Before using your spray can, shake to thoroughly mix the contents. Insert the straw and pull the spray trigger. Ensure that you spray the opening from one position to the next, then repeat the process on the top and bottom. When the foam is sprayed, it expands and hardens within the wall. After the first spray cycle, wait a few minutes before applying a second layer and trimming off the surplus.


Caulk is a means to keep air leaks and energy loss at bay, especially during the colder months of the year. Caulk is frequently used during door installation to also minimize moisture from entering the home. Nonetheless, it tends to break apart and degrade with time. Using equipment as simple as a knife or flathead screwdriver, old and broken caulk may be effectively removed. After removing the old caulk, a new bead can be applied.

Door Sweeps

You just need a thin door sweep if your house’s door is well-insulated. Using a measuring tape, determine the spaces between the floor and the door’s bottom to purchase the right length. If the original sweep is in good working order, there is no need to replace it. If not, It’s best to replace it as promptly as possible.

The bottoms of most doors feature bristle sweeps, and some even have wheels for uneven flooring. It may be necessary to remove the door out of its hinges while replacing the brittle sweeps in some cases. Thereafter, fasten the bristle sweeps in place at the bottom of the door using a screwdriver.


Installing a weatherstrip around your front door is one of the most frequent ways to weatherproof it. A weatherstrip is a piece of material that is wrapped around moveable components such as doors and windows to cover gaps and keep air out.

Installing weatherstrips is usually a breeze. They may be trimmed to your preferred size and usually have a self-adhesive film attached to them. Weatherstrips are often made of foam and rubber, but felt, vinyl, and silicone are also available options. Attach a weatherstrip at the bottom of the door frame, or possibly around the entire door frame, to reduce energy loss and water infiltration.

If you’re experiencing chills near your house’s entrance, the front door is probably to be blamed. Even the tiniest holes in door jambs can allow cold air to enter, increasing your heating expenses. Learning how to seal a front door might help you avoid leaks while also saving you money in the long run. The easiest technique to weatherproof a front door, thankfully, doesn’t need any specific handyman abilities with our abovementioned easy methods.
