Damp Proofing

Rising damp concerns in the living room

Anonymous user 09/03/2024 - 3.19 PM

We moved into our property a year ago and had an independent damp survey done which highlighted some issues that needed remedying. Eventhough the report said there was potential damp, we have had no obvious signs other than the wall being really cold. We only discovered the potential damp, when we redecorated and the paint would not adhere to the bottom of the wall and then created a tide mark. We have since got the paint to dry, with no tide marks, it looks like nothing is wrong. The report mentioned the rendering on the bay window is too far down, the driveway needs lowering and the aco drain needs lowering as its partially covering half of the air brick. The issue we can see externally is a darker patch on the brickwork, which resembles water ingress and its in the place where we have the problem internally. We really don't want to have the walls off back to bare brick, so would like to know if we sorted out the issues externally in the report that this would remedy the damp issue internally?

Are you a tradesperson and able to answer this question?

yes its not rising damp its penetrating damp comming through the brick work even if you hacked all the plater of and rendered the inside it would not stop the damp penetrating the wall you would just have the added problem of now all your internal brickwork is knackered as well lower the external ground level to 150mm below the floor level problem solved

This is certainly not rising damp . The wet bricks will be rain water penetration to those bricks , the only cause of this is extended exposure to water; check meticulously if there is a drip from above that may cause a splashing onto the wall. Low internal wall temperatures will cause dampness on the surface and may prevent paint from drying at the normal rate . Get something pointy and hard and push/ screw it into the plaster just above the skirting to check the plaster ( not render) thickness , if it’s more than 3mm you will also have hygroscopic dampness just from the plaster alone .

Your survey is spot on. But to answer your question, the plaster may still need replacing as just using the wrong type can cause issues in old houses.
