Dry rot - how bad is this?

[opps]

AFAIK wet rot doesn't 'spread' and is more localised, this has definitely spread significantly over 3 months.

Why not get your friend to remove a section of skirting? He will then be able to check the reverse side. The skirting needs to be replaced anyway.

AFAIK, the dry rot spreads because of inadequate air flow. I don't see how an architrave has inadequate air flow.

To be fair there is zero ventilation in that room as the windows are painted shut, and all the woodwork is over 120 years old. There's no signs of rot on the outside of the frames.

dry rot spreads through that red dust which is the spores. If they land on something that has the right food and conditions they'll grow spreading the white threadlike mycellium. It'll carry on spreading until it starts to run out of food, then it creates the fruiting body - like a big flat mushroom, and this creates a new load of spores which drift around hoping for somewhere to land so they can start growing and repeat the process.

Fair play, but from image number 1, I can see water stains on the plaster under the window sill. I don't have a dog in this fight. I hope that it isn't dry rot but I am not convinced that it is dry rot.

That is bad. I can't understand why people sit looking and waiting for it to get worse before they act.

I have dealt with the repairs of two house with severe dry rot. 1 in Harrow and 1 in Finchly. Both of those houses needed over a hundred thousand pounds spent on the repairs.................that was more than 20 years ago.

It's actually rented and initially pre-dates the tenancy. House is up for sale so they wanted to get an idea of how bad it was/how much it might cost to determine if the landlord would sort it whilst in-situ - which doesn't seem likely now, christ!!
