No dpm keyed into dpc

[Chainsawcharlie]

Hi when I look behind my skirting boards I see the wall dpc is about 3 cm above the top of my concrete floor, so as a result that's 3cm of possible damp sat behind my skirting.

It doesn't look or feel wet, and there is no sign of dpm keyed into dpc, just bare blockwork under dpc.
Skirting smells a bit musty.

Should I paint back of new skirting with bitumen, and paint that 3cm of block work below the dpc in the wall?

Thanks

No leave it

No leave it

Is it usual to have such a gap above my flooring level and the wall dpc, wouldn't that part of the wall under the dpc cause dampness behind skirting, hence room smelling musty

If you had a damp problem, you would have rotten skirting.

There are lots of times when the DPC/DPM barriers in a house are not correct, and yest there is no damp problem.

Your musty smell may be from another unrelated issue. You won't have timber floors if you are referring to having a DPM so internal condensation and humidity levels would be your start of investigation as air would be condensing somewhere to create the mould spores that you can smell
