Historic window restoration plus storms vs full replacement under tiered codes—what wins?
Fixing up old windows and putting storm windows on them usually keeps the old time feel of a house. It can also be cheaper in the long run and still fit many energy rules if the codes are set up that way. Swapping out all the windows might save more energy at first, but it costs more and can mess with the original style. What’s best boils down to what you can spend, what the codes say, and how much you care about keeping the place looking like it always has.
