Sealing a door frame is the process of filling the gaps between the door frame and the wall to prevent air, water, and pests from entering the home. This is an important step in weatherproofing a home and can also help to improve the energy efficiency of the home.
There are a variety of materials that can be used to seal a door frame, including caulk, foam sealant, and weatherstripping. The best material to use will depend on the size of the gap and the location of the door frame. For example, caulk is a good option for small gaps, while foam sealant is a good option for larger gaps. Weatherstripping is a good option for sealing the gap between the door and the door frame.
