Weather strip at the bottom of the window.

The weather strip on most of my windows has started to rot. The windows are 18 years old, but the strip is letting moisture into the window sills. How do I replace the weather strip? And what is the cost? Thanks for any help you can offer.

I'm afraid I don't know what you need, which also means I'm not sure how to replace it. There are a ton of different possibilities and we need to narrow it down as best as we can.

To start with, I will need you to try to remove a small sample that is as undamaged as possible and show me a clear picture of the end profile. I know that you said that it's rotting and that getting an undamaged sample will be hard, but please try your best. If any bits of it are damaged or deteriorated then we will not be able to make a recommendation. It's very important.

The video below will go into more detail as to what we need and should be of some help to you moving forward.
