Damp in outhouse joined to house

moonpenny

Can someone offer some advice please?
Doing up a small house with an outhouse used as a utility room and joined to the house on one wall.
This room has had damp issues (possibly still has) and unsure what to do about it.

I have just stripped the wallpaper off and a couple o areas have felt slightly damp.
The main problem is from the bottom of the wall going up about a foot. The wall has been filled and painted but it sounds hollow which makes me wonder what is behind it if anything??????

The house is red brick and on the house buying report it said there was evidence of damp injection been done - there are small filled holes on the outside about 18 ins up.

I am worried the bricks behind the filled walls have disintegrated and if they have how do I remedy and proceed with this?

Any advice welcome!

Bricks don't just disintegrate, even when fully immersed. The hollow sound could be because you're knocking in between where the plasterboard is dot & dabbed to the wall. If you're really worried, time to cut out an inspection channel to find out....

Plenty of threads on here to give you clues about the causes for your damp, though. Is the ground level outside too high? Are there leaking gutters causing water to run down the wall? Any evidence of leaky pipes? Has someone tried to make the house airtight and succeeded to create a large condensation problem?

Thanks phoenix_ww
I don't think the walls are plasterboard. They are too solid (1950s house)
Where the wall is filled it is really roughly finished so really should take it off anyway!

Once it is removed what would you suggest it is filled with? Do you think it would be o.k. to cut plasterboard to fit but fill behind it? The floors are all solid floors.

The guttering was filled with rubbish and was running over, also it has a flat recessed roof but I don,t think it was leaking from that.

The ground outside is pretty low but as you mentioned I have found a couple of air bricks that have had the holes filled in.
