My rotten floor/s

[Doggit]

I think under the circumstances it would be sensible to spray all the walls and joists with wood treatment afterwards just to make sure you don't get any dry rot etc spreading.

that looks more like dry rot that screw driver photo i would get it checked as it cou;d be behind plaster too
but also signs of wet rot

is there any spore looking things on any wood work under there

Dunno, not sure what I am looking for tbh.

Spent the afternoon trying to open up some airbricks. Some were completely sealed. Still not much feeling of air movement under the floor. Reckon I need to make new holes!

Totally blocked up

Cooncrete covering...

Decided a drill was easier ....

What was removed ...

Had a carpenter friend take a look at the weekend (he's too busy to help!) but said that it all looks not too bad, just need a couple bits oof 2 by 4 and some new floorboards and then coat all wood in an all in one preservative. Easy peasy!

It will probably take me about a month! Maybe a job for one big weekend....

Yes it always takes longer than you think! I took up the floorboards in our hall on Saturday and Sunday swept the debris up from the void and removed all the redundant pipework.
After a trip to the tip and homebase, we didn't even get to wickes before it closed.
Then I spent the rest of the evening fitting a new light fitting and drinking wine instead of doing work
I'm estimating it'll take another 3 weekends but we will get used to climbing on the joists.
My point is don't rush it or you'll end up hurting yourself, and most of the time is spent working out how on earth to do things rather than actually doing them! Keep us posted.

Do these look the part?

Will try to add these before putting the new floor down!

They look identical to what I added, other than I got black ones. They were about 1.20 each from a builders merchant nearby so you may over pay online.

Also, bear in mind as long as there's some open area, the position of the air bricks is probably more important than the free area.
A gale blowing through on one corner and a dead zone on the other is worse than a gentle trickle passing right through the floor plan.

Is there a way of working out where any dead zones are? I've got one air brick at the front and one at the back and I can't tell whether it's enough.

Unless your house is 2m wide, if it's an old house it's probably got dead zones. I'd go for one every couple of metres on opposing walls.

So, I decided to start easy.. Just getting some floor up to see what lies beneath. Located first air brick, and a big spider web. Eeuurrgh

That photo is too blurry!

Sounds like things are going well. We have had the boards up a week or so now, and already the wall plate is lifting at one end of a couple due to drying out.

Today is time to knock out the first one see the photo and put the bricks back slightly further from the wall. The floors are built straight on the hardcore oversite but it's better to dig them in as it's not the strongest.

rubbish phone.

How do you take down plasterboard safely? Cut in sections, top to bottom? Or tall sections floor to ceiling, then let them fall after some pulling?

Oh, found the air brick - right behind the massive spider web and joist. Will make a new one ...

Added some more photos: https://photos.app.goo.gl/SzWlcaKi61TSRvDY2

Here's one

Here's the wall that needs to come out - bottom of plasterboard is falling apart... all rotten
