I had my boiler moved and the guy filled the old flue hole with something. Is it mortar? The same stuff that is used to hold the bricks together?
Can you tell by colour? Why is this brown and between the bricks grey? Can you get different colour mortar or does the material dictate it?

So basically, what I'm asking ... is what is it that's used to fill these sorts of holes, because I have a few more on the other side of the house where things have been relocated.
Can I buy something ready to mix with water?
Thanks
