Potential damp advice please

W786 · 7 Nov 2021

Hi guys,

Just wondering if anyone can advise on potential damp issues from the pics attached. Internal walls are wet and some mould builds around downstairs ceiling by main door and wall by cellar. We've had cream injected from outside at a cost of around £800 but doesn't seem to have made any difference.

There was water leaking into the cellar from alleyway underground pipe but that was repaired over a year ago. Damp has been there since before this leak.

Would greatly appreciate the advice.

Looks like a mish-mash of residual damp but also condensation related damp. Have you thought about insulating the external walls?

Any guttering downpipes on the out side?

Post pictures on the external corner.

We've had a qoute of around £10,000 for external wall insulation. Property is solid wall terraced around 1900-1920's.

Also had damp expert around who suggested back to brick upto a certain height and then injection of damp course and then plaster again. He quoted £6,000 for the damp course.

Does the downpipe from the main roof overflow the guttering when it rains?

You could also cut a 150mm on the patio around the house and fill will 20mm stones to help with any drainage issues.

You really need to know if any structural dampness is present? My advice is employ somebody who knows what they are doing and is not connected to a company selling damp products or services. You'll have to pay and it will involve some invasive testing but you could save yourself a lot of money.

I recommend getting a salts test done to help identify the source of the damp, or even better a damp survey.
