Work started this morning on putting the roof back on the existing building. By the end of the day all of the roofing felt and lathes will be on the building. This is a milestone since from this point onwards the building is no longer completely open to the elements.
It will take 7-10 days to get the roof completely finished, assuming there aren’t any problems.
You can also see the two rebuilt chimneys that now match – before the chimney on the left was smaller, rendered and had no string course. The chimneys, as the rest of the external masonry, has been sandblasted over the last weekend.
Well, 7:30pm on Sunday evening and it is all done. Front, back, chimneys, timbers, and 3 fireplaces. It took around 45 bags of sand (each 25kgs) to complete the work. That’s a lot of sand, but I will leave you to do the maths!
It now looks superb, but it isn’t something that I would want to do every weekend!
All the window reveals were cleaned of as much mastic as possible and then cleaned so that the windows can be installed. The old windows were not set equally – some were further out than others – we will fix this issue when fitting the new ones. This is why all the window reveals needed to be cleaned.
The newly rebuilt chimneys were also sandblasted. Dragging all the tubes around isn’t easy work, but it only took 30-40 minutes to sandblast the chimneys. They do look superb.
I will post pictures of sandblasted timber and fireplaces later.
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 outside of the house, the oak roof trusses and the fireplaces are due to be sandblasted this weekend. This also includes the new rebuilt chimneys. There is a lot to get read in the next four days:
- All the oak trusses and purlins need to be re-installed. To be able to do this, the internal wall that holds up the purlins needs to be rebuilt;
- All the windows (upstairs and downstairs) need to be removed as the stone reveals need to be sandblasted before the new windows can be installed;
- The new ashlar stone surrounds for the windows and doors need to be installed. Some of the existing stone surrounds are modern concrete (called “ArtStone”) replacements. These are being removed and replaced with the real thing;
- Two new chimneys need to be rebuilt. One will be using the existing stone, the other will use the stone from the old porch.
The outside of the property is going to be sandblasted. The old gritstone has gone very black over the years. We don’t want to make it look new, but we do want to lighten up the colour.
So today we had a go at sandblasting some test panels – two on the back and one on the front (actually, the front of the barn).
We are going to go with a fairly light sandblasting rather than taking the stone right back. The grime that has built up on the masonry over the years actually makes the stone waterproof. The sandblasting removes this waterproof layer, so after the stone has been sandblasted, it will be treated with a waterproof sealant.
