I'm generally clueless when it comes to DIY and my situation is that I have a baby due in the next few months and the nursery is freezing because of the strong drafts that come through the nursery windows. The landlord is not keen on getting them fixed, and I'm told the windows need new seals. The whole house needs new seals, but for obvious reasons it's really only the nursery we're worried about.
Is there any kind of easy fix to this problem which I could do myself? I don't have a lot of money.
