Need help with plan for patching sheathing on 120-year-old Victorian
Deck was improperly attached to house for decades - rotten siding, rotten sheathing and some rot on the sill beam. Got that all fixed up and it's time to sheath and replace the siding. We are in Canada.
Questions:
There was some combination of insulation in these wall cavities - batting, blown in cellulose and vermiculite. A bunch was lost to the wall being opened up but we don't have much space to access. What should we put in before closing this up? We get high heat and humidity in summer and very cold temperatures in the winter.
You can see in the last photo the depth of sheathing where the rotten sections were cut out - 2 boards each almost 1". What materials should we use to build this out to match that depth?
Seems to be some combination of tattered building paper from throughout the years. Do we add this on this small section and if so what do we do with the top seam?
We do tend to get the occasional mouse in the basement when the temperatures drop for winter. Any tips related to keeping these guys out welcome. We do plan on repointing the foundation along here after and not sure what to do with the small gaps between foundation and sill beam.
Thanks for any and all feedback. Old houses are.....fun.
