Mortar needs to be repointed every 75-100 years. A 1905 house is in that zone. You just have to do it. A correct repointing will last another 75-100 years. If the joints are leaky and sandy, vinyl siding will just cover up a problem that will continue degrading. The degradation will be slower, but it will continue. Not to mention the problem of nailing vinyl siding into sandy joints. The alternative to repointing is to parge the whole wall with a lime based stucco (NOT a fake stucco or cement stucco)
