    My entire wall is damp, will it need replacing?

    Builders

    Hi,
    I recently cleared out under my stairs and found mould growing along the back wall. After clearing it off with mould spray and bleach, I found in the plaster peeling off in the corner. Using a moisture meter I found it to be very damp at least 1.2m high. Will this wall panel need replacing?
    I also checked moisture content along the skirting board and I think all of it in the cupboard will need replacing. mAlso, is this question better for a plasterer or a builder? Maybe I'm asking the wrong people!

    "Hi,
    If you have damp damage then you need to hack off all the render back to the bricks and re-render with waterproof solution mixed in with mortar. Yes it's a builder job."

    "Hi, you will need a builder or plasterer for this one.
    Hack off all the plaster and treat with a slurry mix then re-plaster."

    "Any builder will remove the damp section, re-plaster with a foil back plaster board and tank the walls to prevent it happening again."

    "Sounds like it could be a combination of rising damp and condensation, the best thing to do is to see if the damp is in the wall by drilling 2 small holes and using the prongs on a moisture meter, if there is damp in the wall it could be rising damp if not it's condensation, either way you will need to hack the wall to around 1.5m and tank then re plaster, if its rising damp you would need to add a damp course which can be done with dry rod or cream"

    "Before hacking off the plaster, you need someone with experience to see what is causing the damp problem in the first place? The main cause of damp in cupboards and behind furniture, is condensation, (especially if you have a gas cooker) which may come back after plastering!"

    "Hi, this is Leigh from LB Plastering.
    If you have damp coming in it's more likely it could be your render finish on the outside if you have any hairline cracks.
    With render, water will find it's way in 100%. So you should be looking at the outside first.
    I would recommend using a silicone based render as it is highly waterproof.
    Many thanks,
    Leigh."

    "The wall will need stripping of old plaster to 1.2m high then treated by injecting damp proofing chemicals then once dry replastered with which ever system will be best for the situation.

    "You can use a Plasterer or Builder as long as they know what they doing I would recommend damproof plaster and skim over it."
