I asked this question on the insulation board but this might be a better place for this question.
I'm repairing and painting my house so I thought it would be a good time to insulate the the walls on the old part.
The original house was built in 1938 and has 9" dutch lap or v-rustic siding. There is no sheathing just tar paper and the siding.
I was thinking of doing dense pack cellulose.
I can't find a blower to rent that will do dense pack are the Home Depot style good enough?
How do I patch the holes so they don't show? The companies I've called that are reasonably priced don't patch.
If I or they drill through the siding how do I best patch the holes?
Or should I remove a row of siding at the top and bottom of the wall staple the tar paper and put up some osb in place of the siding while they blow it in and then replace the siding?
