oven causing damp and mould

Rach273

We had our kitchen fitted in June, replacing a freestanding oven with an integrated double oven. The wall behind the new oven units was tiled, but these were removed to allow the cabinets to fit flush, and I don't think the wall was sealed or plastered.
Now there are large patches of damp and black mould coming through on the other side of the wall.
this is an internal wall, and the water pipes run along a different side, so fairly sure there are no leaking pipes or rising damp.
I am assuming this means that the oven is not sufficiently ventilated, or that the wall should have been sealed in some way?
Any ideas on the best way to remedy this? Thanks!

Was the oven fitted exactly in accordance with the manufacturer's specifications, with the minimum clearances and ventilation adhered to? It does sound as if there's insufficient clearance which is allowing steam to build up behind it and dampen the wall. The remedy is to refit the oven properly if that's the case.

If it has been fitted correctly, then you need to do something to protect the wall, such as tiling or some other sealant, but that vapour has to go somewhere so you may just end up moving the problem.

I would expect a nice warm oven to reduce damp, not cause it. There should be ventilation above & below the oven but that is to let the warm air escape.

I assume that this is a gas oven, as that would kick out a lot of water vapour. With insufficient ventilation I imagine you'd get a wet wall.

Kitchen fitted by whom? Tiles removed by whom? Have you contacted the kitchen fitter/ electrician/ BPEC ventilation installer?

Large patches of damp and mould suggest more water than normal oven use. Reasess both rooms ventilation strategies. Extractor fan noise =/= effectiveness (ie. not as any reasonable person would expect). Use lids on all cooking pans/ pots in and on cooker.
