When it comes to your home, there is always going to be some air leaking in, it is inevitable. In fact, having a home that is sealed too tightly could cause a problem on its own, but excessive leaks will increase the cost of keeping a pleasant temperature in your home, and it can also lead to outside noise and odors leaking in.
The most common culprits when it comes to leaks are your doors and windows. These are the weak spots in your building, but that doesn’t mean that you can’t do anything to minimize the impact they have.
For example, if you have a lot of cracks and holes around your window, this should be addressed. It is definitely something that you can attempt on your own. If there is rot in the wood around your window, you should make sure to completely remove all traces of it, since it can resurface if left behind. You can then use wood filler to create an even surface to paint over.
