We are in the same boat - moved into our house in 2016 that was built in 2001, and it was obvious the previous owners didn't know how to run an air exchanger in the winter or do preventative maintenance on the wood-frame windows. We did the best we could over the past 5 years sanding down and sealing over what was left, but the damage was done. While we havent necessarily agreed with the blanket approach of printing money and throwing stimulus dollars at everyone within certain income thresholds regardless of whether COVID has significantly limited earnings, we've banked most of the stimulus for a window and 2 patio door replacement project....1st quote we got was insanely expensive, next two were pricey but more in line with what we were expecting. Not getting top of the line but having to do full replacements (not inserts). Increased costs for these type of projects are a combo of higher material costs due to demand/lack of supply and demand on licensed/bonded contractors. The surge in new construction homes/development is driving window prices steadily up due to that pent up demand - at least temporarily. All in we are looking at $25K for the project, but we have quite a few windows and the pair of patio doors is a big chunk, too. Thanks for the insight. When I looked at the house we bought the inside of the windows were insanely wet and had mold on them...it looked like a tropical rainstorm had happened inside the house. I would guess 24/7 365 days a year water was sitting at the bottom of the window soaking the wood. The first thing I did was plug in the air exchanger and changed the filter that hadn't been replaced since 2006. Good thing the other filter in the 2-pack bought in 2006 was sitting right there. Now it is nice and dry. I don't understand how the previous owner lived like that and all they had to do was plug a cord in to let the automated system do it's thing.
