Foundation damaged and needs to be mortared again? Check the age of your house before you a hire someone. Older houses in South Jersey (pre-1920) were sometimes built with limestone mortar. Standard mortar that would be used to fix modern houses will crack when it cures in limestone foundations and not hold well. Consult a specialist who has familiarity with limestone so that they can provide a proper mix for your repair.
