I just purchased a home and the garage is partially built into a hill. As a result there is dirt up to the 2nd horizontal siding board in the back of the garage. Along the sides the hill slopes down to where the dirt is even with the concrete at the front of the garage.
I know having dirt up against wood siding is bad, so I dug out a trench about 6-8" wide and deep enough to expose 6-8" of the concrete foundation.
What I don't know is what should I fill this with and how deep should I fill it?
Should I look at having more dirt removed, because outside of the 6-8" wide trench the dirt is still at a height even with the 2nd siding board? Maybe make the trench 12" wide?
Do I need to incorporate aluminum flashing somehow to further protect the siding?
Any suggestions would be greatly appreciated!
