Just in case anybody else has this problem I think I’ve worked out it’s a blocked pump. The blending valve is shutting flow to the circuit and because the Grundfos pump is blocked it’s not circulating water through the UFH pipes and hence the temp isn’t dropping down as it should so the blending...

I had a guy do some work on my house including installing wet underfloor heating before the screed in my extension went down. I have a hetta system with two zones. I zone for the conservatory and 1 zone (with 2 pipe runs) for the lounge. The guy who did it did some other work for me and he...

we are just finished off an extension that has cavity wall with 75mm gap between block and brick. We would like to add a balanced flue fire but the one we like is 36cm deep and so with a false chimney breast and the fireplace surround would stick out too far into our room. Does anybody know the...

That’s good to know re the lead. Regarding the paper I guess it’s just personal preference but I don’t like paper anywhere really. I find that eventually it gets damp behind especially around windows and it’s my goal to eliminate it everywhere in my house. My wife puts washing on the radiators...

Thanks for the replies. House is 1979/1980 so hopefully nothing too nasty in the paint if I start sanding. Could potentially have lead so don’t want to do too much sandings. Don’t really want lining paper so will experiment with a few things to try and get a good acceptable finish. If it’s awful...

Hi All, I’ve been stripping wall paper and some of it has some very flaky paint underneath. I used a razor blade scraper to remove all the bad stuff and then a bit more and basically left with half a wall of good paint and half stripped back to a grey smooth type plaster. I’m wondering what my...

Just one slab to cover the whole site 200mm deep with reinforcing rods within. On one side and the front there is a trench but concrete depth is only 200mm below ground level (so 200mm deep over most of the site and 400mm deep on one side wall and front where the trench is). Return wall there is...

Hi, could somebody advise me on a conservatory base. My builder was supposed to build a 500mm deep trench around the outside for a 600mm dwarf wall to be built on. Ground conditions are sand which apparently is good. I saw the trench along the front and one side but have returned today and he...

Thanks very much for the replies. All joist hangered up now

Do you know where it says 38mm as a minimum bearing because it would be good to use it when I talk to him? I can only see 75mm as minimum bearing joist to wall plate in approved document A. Cheers

I removed plasterboard to check as I asked for a joist hanger when i say how narrow the support was but he hasn’t done it. Like you say too risky even if calcs said was ok but don’t see how they could. With setttlement and seasonal movement and drying 1cm is not enough to be safe.

I would think wood could shrink and warp by this amount as it dries out couldn’t it?

Builder changed to a double at my request. But what about this? Surely a 1cm bearing for a floor joist can’t be right can it?

Hi thanks for the replies. It seems that it may be acceptable I suspect building control will want double joists unless calculations show it to be acceptable as it is. But the calcs will cost more than changing he joist

Hi all, After a bit of advice as I have a few concerns regarding some work I am having done. In an extension the trimming around the staircase looks pretty bad to me and I’m after some opinions as to whether it is acceptable. My understanding is that joists should be doubled up around the...
