I once ran over a badger and the blood diffused with the tarmac and the road was never damp again. Does that mean I can treat damp?

You still haven't answered my questions lol Adapt-and also every time a external door opens its going to cause an intake of air from the outside Reading the above you clearly have never measured differential vapour pressure when doing a condensation survey, BS5250 :2002 the pressure is greater...

I got a ccj, is that any good :RpS_thumbup:

Im not on about checking chimneys lol.......extract fans lower the pressure in a building, which can cause the spillage of combustion products from open flue appliances. Which means the combustion gases may fill the room instead of going up the chimney!!!! How do you check this? Do you know what...

I take tour point about how long you have been doing your job, but the BPEC IS A MUST!!! Do you know how a PSV system works and how to check it? Where to fit a piv and why? Airflow requirements and measurement, how do you measure airflow? Installation with combustion appliances in the...

Seems like you understand a condensation survey, it's also good to check externally for defects as this can make the walls just below dew point if there is a penetrating damp issue. Even simply allowing good evaporation at the base of external walls will also help with condensation as there is...

How do you check the internal environment for condensation problems? What make of fans do you recommend?

@adapt sorry for the delay! Not sure how much you know about condensation!? Condensation is best to combat at source i.e. kitchen and bathroom, as this is where most moisture is produced, first thing I would do is to lower the relative humidity.

What was the spec?

First thing you need is Professional Indemnity Insurance before you even think about looking at a job….

Brilliant advice from Dry rot. Definitely need humidistat fans to lower the internal RH to 65%, keep furniture off of external walls especially North facing. Trust me I'm a thermal imaging geek!
