Bedford Stone Homes

If I am not mistaken by the photos it an Ashlar block. Precast stone. Cement product.
They absorb water after years of weather..
Water proofing. Not any water profiting. You have to know want you are doing.
So, masonry bedding has been affected by saturation.
The sill plate if soaked.
Flash the foundations top.
Cut into bedding 1.5 inches and flash with tin, gal, what ever.

Look to me its Ashlar cement product. Foe- stone.
Have laid it repaired it, and its big at one time in Montreal Canada. late 1950- 1960-and into 1970 then slowed down. Cheap to buy compared to real brown or gray stone.
That I bought reclaimed for repairs.50- 70 percent of the price for Ashlar.
No maintenance. Everything went south because of no maintenance.
Sorry for the edit.
I am a mason.
Facade company still working.
Sorry I did not say anything before. Please I am leery of help non members.
Fix.
1: gutters and down spout leaking to me. New over size 5 inch.
2: all new joints. Total point.
3: flash the foundation and sill plate.
those blocks in basement are soaked.
4: posable freanch drain.
5: water proofing ashlar foe-stone. Not any water proofing. Do it wrong and you change the color of the foe-stone and more, much more.. Stone has to be washed first. Have to know what you are doing again.
