It can be difficult to replace weather stripping, depending on the type of weather stripping that is being replaced. If the weather stripping is just a piece of foam or rubber that sits against the door or window frame, then it should be a relatively easy task. If there is tape or adhesive involved in holding the weather stripping in place, it can be more difficult to replace.

It's not difficult to replace weather stripping, but it can be a bit time-consuming. You'll need to remove the old stripping, clean the surface of the door or window frame, and then install the new stripping. There are a few different types of weatherstripping, so be sure to choose the type that is best suited for your needs. Foam weatherstripping is cheap and easy to install, but it doesn't offer much insulation. Rubber or vinyl weatherstripping is more expensive but better at insulating and sealing out drafts. Finally, metal weatherstripping is the most durable but also the most expensive.
