Prioritizing Weatherization Upgrades
My wife and I purchased a 1920’s home located in beautiful NJ! Located in zone 5A, it came complete with 4 different crawl space/basement configurations, balloon framing with zero exterior wall insulation, and no central air.
The previous owners had just completed a partial renovation including the kitchen and bathrooms. All windows and half the exterior doors have also been updated in this century.
I want to do something to improve the comfort and air quality of the home. But I don’t know where to start. I know the air tightness is awful. The basement has multiple sections in various states from crawl space with dirt floor to bare bones unfinished basement. The attic isn’t even on my radar because it’s so hard to access.
So, what would be a good first and second step? Is insulating the various basement/ crawl space sections even worth considering with such awful air sealing? I’m confident that I could DIY the majority of that. Would that even make a noticable difference? Or, should I prioritize an exterior renovation with new siding, insulation, and air sealing? That is obviously a huge project and would take time to complete.
As a bandaid for cold winter months and uncomfortably low humidity, would it be sensible to install a home humidification system like the Aprilaire 865?
I’m already having 2 renovation companies come out but I wanted to get more information before seeing them.
