The first job is to clean up the new roof timbers. These had been previously been coated with Osmo UV Protection oil. This was necessary as the oak was exposed to the elements while the roof was being built. If we had left it untreated, the mud and rain would have soaked into the wood and been very difficult to remove.
Cleaning up the oak involves softening up the previously applied Osmo with white spirit. Then rubbed it down with wire wool, before finally wiping it down with a clean cloth and white spirit. The more persistent marks will be sanded out. Fortunately, there aren’t too many of these. The final stage will be a second cost of Osmo (this time the internal PolyX version) to reseal the wood.
By the time we get to the end of the first day, the beams in the kitchen have been cleaned ready for a coat of Osmo next week.
We have had a couple of problems with water leaking into the building – one from under the floor and the other through the roof.
When the new concrete floors were laid in the extension, a 75mm insulation board was put down first and then 75mm of screed on top. The underfloor heating pipes are fixed to the top of the insulation boards and the screed is laid on top. The hot and cold water to the bathrooms, along with the heating for the towel rails, is run underneath the insulation. We pressure tested all of the pipework before laying the screed, but unfortunately it looks as if we have a leak in one of the downstairs bathrooms. The underfloor heating is fine since it is maintaining pressure (if there was a leak the pressure would drop) and the floor seems to have started to dry out now that we have turned off the water to this part of the building. Next job is to dig up part of the screed to find the leak. This shouldn’t be too bad as the wet marks in the floor are giving us a clue where the leak is! The last place to dry on the floor is probably where we will find the leak! A job for this week.
The next problem is in my study. Rain appears to be getting in the joint between the roof and the wall. The roof here is a simple mono pitch roof. We have increased the height of the lead upstand on the outside. This has improved the situation, but rain is still clearly getting through. We believe that the rain is soaking into the exterior stonework and then running down behind the lead. One way of solving this is to treat the exterior stonework with waterproofer – something like Clear Cladding from Belzona. Unfortunately, all of the suppliers have been closed over the Christmas period, so we will have to wait until the new year before addressing this one.
We have 14 workmen onsite today – 2 plumbers, 3 builders, 2 heating engineers, 2 plasterers, 3 electricians, 1 joiner and 1 roofer. And me.
Trying to make sure that everyone has enough space to work is the main problem, but everyone seems to be getting along (just). The car (or van) parking situation is causing a little bit of a problem, but with the wet weather recently, it is jsut to muddy to get vehicles into the back field.
However, it does mean that we are making a lot of progress.
We have made quite a bit of progress this week:
- The ground source heat pump arrived on Monday and, fingers crossed, we hope to have it up and running by the end of the week. It will be good to get some heat in the house to start drying out the walls and floors;
- The plasterers are back. We need to get the old part of the building finished off so that the decorators can start after Christmas;
- We have started pointing the stonework. We are going to have to pick the days carefully as this can only be done in dry weather (otherwise, the rain will wash the pointing out);
- We have almost finished the upstairs bathroom. It will be good to get this one put to bed before Christmas. If the ground source heat pump is turned on at the end of the week, we may have some hot and cold water in the old house.
Now the scaffolding has been removed, we can sandblast the stonework on the new extension. We tend to do the sandblasting at the weekend because it is so noisy and messy. It just makes it to difficult to work on the site while the sandblasting is going on.
The next stage will be to point the stonework. We will be using the same lime and Nosterfield River sand mortar that we used on the original part of the property.
All of this stone has been brought in from offsite and is the closest match the we could find. The one exception are the quoins (the large corner stones) on the porch. These originally form part of the barn that was where the kitchen is now.
We have started to remove the scaffolding from the extension. There is still some work to be completed on the porch, but most of the external building work is drawing to a close.
Taking the scaffolding down has made a tremendous difference to the overall appearance of the property – it is starting to feel like a real house now!
We have had another fine day here in West Yorkshire. This has allowed the roofers to get on with their job. We have definitely passed the half way mark on the extension roof.
We are making some good progress on the extension roof. All of the Velux lights in the rear elevation have now been installed. This includes an additional pair that we put into the master bedroom. The master bedroom has bi-folding doors, but no other windows. If you want to sleep with the window open at night, the only option would have been to leave the bi-folding doors open. Probably not a good option on the ground floor.
So we decided to add a pair of Velux lights. We have put them on the rear elevation since most of the bad weather hits the property from the front. We were concerned about the amount of noise that rain would make on these windows in bad weather (not that we get bad weather in Yorkshire!). We will have to get some electric blinds fitted to these as there are about 4m above the bed!
We are using reclaimed stone slates on the new extension roof. These are fairly common in this area on properties on this age. By using reclaimed slates, this roof should match the roof on the existing property. Just because these slates are reclaimed, don’t think that they are cheap. They aren’t! They can also be quite difficult to get hold of, particularly if you are after a reasonable quantity. We were lucky and came across some a couple of months ago. We bought them and stored them offsite on pallets until we needed them.
We have made quite a bit of progress on the porch in the last week or so. The roof joists went in today. There are a pair of Veluxes in the front of the porch roof.
The porch extends with a canopy that covers the front door. However, we won’t be able to finish this until the scaffolding is removed. And we can’t do that until the main roof is finished – probably in about a week’s time.
The stone in the porch needs to be sand-blasted before it can be pointed. At which point, it should be a pretty close match to the existing property.
