I recently inherited an old Cape - built in circa 1796.
The foundation is built of stones and topped with some very immense (?) granite blocks - it's really quite amazing!. My parents renovated the house in 1997 and lally columns and some new support beams were installed (some old hand hewn beams remain though).
My brother told me some of the foundation walls need to be re-podged (?sp).
What does this entail? Do I get a mason to do this work?

Also once I have the work done,would I benefit from using a dehumidifier down there? The cellar is not wet, but it is damp enough to keep a small colony of spotted salamanders happy . Would a dehumidifier dry out the the old wood too much?
Thanks for any help and advice!
