I have three big projects coming up:
- Replacing all the windows and a sliding glass door
- Adding 2 inches of rigid foam insulation to the exterior and re-stucco-ing
- Adding rigid foam insulation against the footings
Since these three projects each interact with elements of the other two, I'm unsure of which one to do first.
I'm worried that if I have a bunch of guys put in new windows first, for example, when I go to increase the effective thickness of the wall by about 2 inches due to the foam insulation, I'll run into problems with window flashing. But if I do the wall project first, how am I going to handle the existing windows? If I add footing insulation first, I need to flash it properly against the old stucco that I'm planning to remove or cover up anyway...
Are these three things that should be done all at the same time?
