Back on the self-build waggon...

Well done mate, grand job. My friend recently bought a bungalow and had a full structural survey (£900) which found a few roof problems, on moving in the removal man (carrying a tv) fell through the floor!!!, turns out the whole ground floor was riddled with woodwork and all had to be replaced. They tried to claim from the surveyor but the reply was “we are not allowed to lift carpet so could not see it” .?

Yeah its a horrible thing, and not covered by normal house insurance. The people who had the house clearly knew about it, as there were sections of timber which had been replaced in the bathroom, but of course nothing was said.

 

Its not the end of the world I suppose, at least I can sort it myself, and having done the loft, those timbers are all OK thankfully! I too have fallen through the floor in the existing kitchen, one of the floorboards was so bad.

 

We never paid for a survey, i've lived on the street all my life, so I know the houses well, and my dad was a builder, so we just had standard valuation, i don't think we would have found anything else out having paid for a survey to be honest, all the bad things have been covered up which i'm now uncovering and fixing.

Always a good idea to jump up and down on each suspended floor. If you can get away with it.

 

Ideally take Giant Haystacks along with you to do it ?.

 

Very good piece, Mike.

 

How have you dealt with potential moisture permeability in your new floor?

 

Was the strategy been with close off the airbricks to keep moisture out, or perhaps deem it to be marginal given the use of PIR?

I did go and look at the place as my mate asked me to, and I did jump up and down but I only weight 9st soaking wet and the place was full of furniture!!!!. Also my mate pointed out his structural survey which cost ££££ pointed  out the same issues I did. In future I would recommend anyone Buying to lift various bits of carpet in all rooms. (I have 20/20 hindsight ?).

Air bricks are fully open, the original ones which were built in with the house (one double airbrick either side of the sleeper wall), but they had piles of soil behind them due to previous owners building the level of the patio up, which we reduced in height when we first bought (there was 5 layers of different materials patios under there!!). I've also lined the airbrick channels with Marmox Multiboard to stop anything dropping down from the cavity, and also to stop air going up quite as freely into the cavity.

 

Remaining build up is:

Treated Timber with 100mm Phenolic foam

AVCL in the form of Protect Barriair Membrane

18mm OSB3 TGV4 Floorboards
