I have a 50 year old house and 50 year old windows. This winter I
noticed that the original glazing had been chipping off and the only
thing holding some of the panes in place was paint so I resolved to
reglaze the windows this spring (no summer). Should I just replace
them? They are pretty air-tight and I did not feel much of a breeze
coming through them except for the coldest and windiest days of the
winter and a lot of that I attribute to the old glazing. Each window
has a storm window but the inside window does feel very cold to the
touch in the winter so I'm not sure how much they help. I'm trying to
weight the cost of replacing the windows with the savings that I will
realize for replacing as opposed to the savings I will get from
reglazing.

Here's a picture of the window

What would you do in this situation?

Energy Star Low e Argon windows will save probably 10-20% on your
bills depending on brand and how bad yours are, Attic insulation is
most important, if you live in a cold winter area going alot above
code minimums is smart. Attics are the cheapest to do, windows and
walls cost the most. You need an energy audit done to see what you
have and what you can save. This is a Blower Door test that gives an
accurate printout of how many air exchanges your home has and how many
it should have. The tech will pinpoint air leaks with a smoke stick so
you know what to fix. Then a load calculation is done to see where you
are now and where you can go with windows and insulation. Many bigger
heating contractors have blower door test equipment and should know
how to do a load calculation. www.energystar.gov is a good place to
start reading.
