Hi all,

I live in a 1950s Bungalow which has concrete flooring. We have started getting pretty bad damp and mold on some walls and ceilings in the house. I was looking to install a few of these on the exterior walls woth 1 at the top and one at the bottom on the exterior walls a meter apart. All glazing in the house is brand new with vents as we thought that might also be a contributing factor but we are still get damp.

I was looking at the below? Would these be OK? I was going to put them all around the exterior brickwork of the house?

No, weep vents are for a completely different purpose.

First you need to define what is causing the "damp". Then you determine how to deal with it - if it is condensation related, then it may need lifestyle changes instead of or in addition to physical changes to the building.
 
It's just that I have no weep holes at all and the damp seems to be pretty much worse on these walls. Do I need airbrick type vents?? Not one room in house, 5 in total have any type of ventilation - absolutely nothing, no air bricks, vents at all

Can you please explain what weep vents are actually for out of interest.

They’re to divert water which has got in between the inner and outer skin of a cavity wall, back out of the outer skin. Normally fitted above lintels/openings.
 
Thanks. Looks like I've got a big problem then. I thought If I installed these or brick vents it would improve. It's only during the winter months when it gets bad aswell.

Need to do something pretty soon as I don't have the finances to get a tradesman to come in.
 
Finding and rectifying the source of water is the first step.

Post some photos of the damp patches, inside and out, with something to show scale, and of the entire wall from roof to ground. Include the gutters, downpipes, drains, manholes and plumbing, including radiator pipes, and indicate the position of the DPC relative to ground level and paving.
 
Yes as JD says above. More detail is required.

You do not want to go randomly fitting vents, or doing anything really until you have properly identified the problem you are trying to remedy.
