The Accrington brickwork requires repointing and a couple of firms are
giving me estimates. One tells me that mastic is the best material to
use the other tells me red sand and cement is best. Both say that a
rub down with oil will give a good appearance.
I know nothing of these things. What is the groups opinion on the best
way to go, please, mastic or sand and cement?

Not answering the question, but what is different about "accrington"
brick to any other brick ?
Using mastic to repoint bricks sounds bizzarre, also rubbing down with
oil.
Are these bricks glazed or something ?
