This question already has an answer here:
I purchased my 110 year old colonial house 6 months ago. It has a field stone foundation that looks completely original (with a few small repairs). The house is located in North Eastern Massachusetts and is exposed to the worst of the elements around here. This has lead to the walls of the foundation starting to crumble, the mortar is loose on most of the wall and unstable. I can peel pieces off with my fingers. When I "knock" on the joints it almost sounds hollow. this is widespread throughout the basement. However the walls seem solid enough.
My question... I want to sure up these walls. I want to get a more water/rodent tight perimeter.
- What are the steps I need to take?
- How much of the old mortar should I remove? if I removed all of the "loose stuff" it seems like this project would take months! years even!
- What kind of mortar can I use as a replacement? I read online that its bad to use Portland cement? Best to use Type N Lime mortar?
- What tools will I need?
- Is this a do-it-yourself job? or should I hire someone?
thanks for any info... getting really nervous about this project!
