Hello, I am having 11 windows replaced pretty soon (wood replaced with vinyl), and I was wondering if there is additional weatherproofing and/or insulating that would be best performed at the same time as the window replacement. Something that I do not want to realize later and say "I wish I had done that at the same time...." Our house is very poorly insulated which I hope to resolve a little bit at a time. It is a brick house with plaster walls and double hung pretty standard windows. I live in Baltimore MD, we have all 4 seasons pretty thoroughly. In the winter we have cold days but rarely cold stretches. We get a fair amount of rain in the spring/fall, and a lot of humidity in the summer. Thanks for any advice, and please let me know if I am posting in the wrong place.
PS - I posted in "walls and ceilings" before before I found this thread,
