  • I know exactly what you mean, I had the same issue in my old apartment. At first, I tried simple fixes like weatherstripping and sealing small gaps, and that actually helped more than I expected. Later on, I added thicker curtains, which made a noticeable difference at night. It’s not always about replacing everything right away, sometimes small adjustments can reduce heat loss quite a bit. Of course, if the windows are really old, upgrades might be worth considering, but I’d start with the basics first and see how much it improves your situation.


  • I went through something similar, and I’d say combining a few approaches works best. What are typical windows replacement cost in GTA these days? Sealing gaps is a good start, but insulation film kits and proper window coverings can also help trap heat inside. In my case, I realized my windows themselves were part of the problem, so I looked into better options. While researching, I came across this resource, it explains different ways to reduce heat loss and what to look for if you’re thinking long-term. It helped me understand what was actually worth fixing versus replacing.
