Are you sure those boards were original. I've owned quite a few
Victorian properties and never come across T&G floorboards.

arent's house was (late) Victorian and had original T&G floors and
cavity walls. Spoilt be not having an effective DPC.

Mine has no DPC - but no damp. The floors are above ground level so any
rising damp stays in the cellar. There's also a high skirting board with
no plaster behind it - even more of an area for any moisture to evaporate
off.


DPCs are a good thing -- BUT the reality is that they're really a cheap
substitute for adequate drainage of the site. If the site is
well-drained to start with, then a dpc is a work of supererogation. If
the water table is kept low enough by adequate site drainage a dpc has
nothing to do.
