- Damp Sam had a call from a concerned woman in Huddersfield who had a reputable company and fellow PCA members tell her he thought she had DrRot. The lady forwarded the pictures that the company surveyor had taken in the sub floor and straight away we were not convinced. The surveyor also said she should have the underside of the timbers treated as a precaution against woodworm and recommend wall plaster above was hacked off up to the picture rail.
above the air brick thats bringing cold air in making the plaster damp/moist would it be wise to put expanding foam where the floorboards meet the wall to fill in any gaps stopping the cold air coming up to the plaster.?
Mark Croft yes that’s a good idea, when ever we do any work in areas like that it’s the first thing we do. 👍
The white looks like calcium.. brick and cement salts ..
No .. fluffy white stuff ..
And dry rot needs a wet source..
Should start with wet rot ..
Damp ..
And if you can find out the source of damp ..
Then that's the start of the wet rot .. then turns into dry rot ..
The feet in wet and will then grow into a massive , expensive white fluffy dry rot problem.. and it can grow behind everything ..
And dry rot .. has it's roots in wet ..
So find the source..
And then treat everything near it ... And everything in 2mts or more from the source..
If I'm under the floor..
Everything is getting sprayed ..
And all the wet rot is taken care of ..
And any rotten wood has gone and the structural integrity has been replaced
Do or would you also advise the home owner to have the pipes insulated....to help save a bit of cash and prevent bursts...especially, as you mentioned, it was a well ventilated area (cold /draughty).
ningis21 they possibly should be lagged although I'm not sure how much money it would save. That's more a job for the heating engineer. It may stop them ever freezing in sub zero temperatures.
