Damp Proofing Question

Solution required for penetrating damp

Hi

I rent out a 1930's 3 bedroom semi in BD19 postcode and I'm looking for a solution for a damp problem probably caused by poor ventilation. Please see below:

Mold patches / spores around the main bedroom window where the ceiling meets the wall. Also in a cupboard where an old storage tank used to be located (mold spores on the ceiling) with a permanent foisty smell generally throughout the room.

Wet wall underneath the window, condensation is the expected cause, but another reason may exist as it gets very wet.

I will be looking at installing some trickle vents to reduce / eliminate the condensation, however I suspect that the penetrating damp is being caused by either poor pointing and or problems with the fascia, soffit and / or gutter.

If anyone can provide a solution it would be appreciated!

Without seeing the property its very tricky to give you all the answers.
It's a fine balancing act of heating, venting and insulating; putting in the trickle vent is the best course of action to see if that controls the condensation. Then I would add insulation where possible without too much disruption.
Are you sure the damp is penetrating from the outside? Check over flows from tanks and wc's that they are not obstructed or broken.
You may be forced to employ a surveyor to evaluate the building to assess the possible failing of the fabric and then resolve the problem.
Condensation is one of the most asked questions on this website, but the answer is always allowing ventilation to rooms.
Hope that helps
