- Specialist damp surveyor Bryan Hindle talks about one of the site situations where a rising damp moisture meter profile is not caused by failure of a damp proof course. This damp survey from a property in Leeds, West Yorkshire. Further details on damp survey methods and our services are available on the following web page.

Great video Brian, thanks very much for taking the time to share this.
excellent informative work. thanks from a trainee surveyor
Good job. Thanks for such an informative video.
Very good video.
I am helping me son who has just moved into a Victorian ground floor flat , the front is below ground level and the rear leads out level to the garden . There are a number of damp patches inside, the floor is not that long ago pine type floorboards. On the outside I can't see any air bricks to the rear elevation but on a part set back there is a large square air vent which doesn't seem to go below the floorboard level.
I don't know what is below the floorboards and am assuming there are floor joists. I also don't know if there is a dpm on the house.
On the rear elevation there is a cement render which looks like it was done in the last few years, part of it by the rainwater down pipe needed re rendering which I have done and I have also tidied up the rainwater drain which needed attention.
After watching your video I am now able to understand how important it is to analyse it correctly and the I am unsure of why there doesn't appear to be air bricks could they be buried under concrete patio bit.
Any advise would be greatly appreciated.
Best regards
Nick Barclay
Great video
great work
nice video - what about damp at the base of an internal wall nowhere near a external wall?
Per war property that has cavity wall insulation installed 2012. Discovered dry rot in the front bay window area this week. Have removed all flooring timbers and joists. Found cavity wall insulation breaching the cavity and filling air bricks any recommendations ?
wouldn't it be a good idea to get rid of the external pants and let the house dry as the plastic paint will hold damp in the walls.
Hi Phil, good question. Well that would be a good thing but the paint is already there and removal of it would be costly. This home has a cavity wall so most of the moisture produced in the building will evaporate via that (there are 'one' air bricks through it. Mechanical extraction in the wet rooms is a must - it is double glazed and the fireplace are bricked-up. The paint can be tolerated.
