It is going to take a couple of days to sandblast the outside of the property, the fireplaces (x3) and the oak trusses and purlins in the roof. This work is being done at the weekend, so that it doesn’t interrupt any of the building work – no one can really work on site while the sandblasting is going on due to the noise and dust.
Proceedings didn’t start until just after lunch, but by 4:30pm the rear and one side of the property had been cleaned including one of the fireplaces. The idea is to gently lighten the stone and remove some of the black grime and soot that has built up over the last couple of hundred years. This dark outer layer keeps moisture out, so once the stone has been cleaned, it will need to be treated with a sealant.

The stonework to the right has been lightly sandblasted to take some of the black soot and grime off the old stonework. Ironically, it is the grime that makes the stone waterproof, so once it has been sandblasted the stone will be treated with a sealant.
