Bought a house last year. The previous owners had all new windows installed two years before we bought it (we lived next door and saw the guys doing the job).
Had an energy audit done on the house, only to find out the guys who installed the windows cut corners and didn't put inuslation around the windows before installing them, hence we get a lot of drafts.
The energy audtior said the ultimate solution is to take out the windows, insulate them, and reinstall them. However, he said there's the risk of damaging the windows doing this procedure... not too mention the time and expense.

So, I'm wondering, will caulking the windows and frames on the inside and outside be a reasonable alternative, or should I just bite the bullet and go for the energy auditor's solution?
