Gone West

Would it be a good idea to have an airtightness test done. Then you can also see where the leaks are.

Western Red Cedar doesn't need any treatment to stop rot and lasts for around seventy years. It will go grey without any surface treatment, which some people like and some don't. You will find the rain washed areas go grey quicker than the weather protected areas, so can look patchy until it all evens up, which can take years.

Depends what sort of wood it is, and what if any, surface treatment you intend to use. I would use Cedral myself.

At our last place we had 1920s asbestos roof slates that were just about 100% covered in moss.

I use mostly Soudal foams, sealants and adhesives. I don't think you can beat them.

Although you don't own the hedge the boundary should be the centre line of the hedge plant trunks.

I don't want to rain on your parade, but it would take me years to fill a compost bin that is, what looks like, over 2m high and 4m diameter. That's from my just over half an acre, sounds like a plan for the National Trust. Our compost bins rot down very quickly.

Great job.

Is that measurement to the centre line of the hedge or your side of the hedge?

Yes and then no. I designed and built my own PH but it wasn't recent, it was fifteen years ago, when the regulations were less onerous and costs much less. It took us eight years, doing a lot of the work ourselves. I would do a new self build now, but it would be a turnkey build.

The fresh air is coming from the loft, same as if I had a PIV system.

"On 31 March 2003, they were banned from use on roads in the United Kingdom because of safety concerns. They were all called in and crushed, though a few survive in museums and private ownership."

I have fitted several new windows already which don't have trickle vents. I don't like the look of trickle vents, and retro fitting them seems like much more of a PITA than a small hole on the ceiling.

This is an old bungalow, so is there any reason I shouldn't have ceiling mounted humidity activated vents in the dry rooms?

Surely whether humidity activated or manual, when open, they rely on the wind to work. I thought the idea that trickle vents worked correctly, had been debunked years ago.
