What Was the Biggest Mistake During Your Window Renovation?

We completely underestimated the structural repairs needed once the old frames came off. Turns out we had hidden water damage in the drywall that added an extra grand to our original estimate. Another tip is to carefully consider how the windows open; we chose single-hung for the guest room but now realize double-hung would have been way easier to clean from the inside. Luckily, we found a comprehensive new window installation cost guide very helpful for budgeting beforehand, so we actually had some emergency contingency funds set aside to cover the unexpected carpentry work.

I’m in the planning stage of a window renovation project and trying to avoid common mistakes. For those who have already completed one, what went wrong that you didn’t expect? Did you choose the wrong style, underestimate costs, or have installation problems? If you could start over, what would you do differently to get better results?
