What's the root cause?

The damp can be coming from a few different places... Up through the ground if there is a fault in the damp-proof course.

In through the walls or windows if there are problems there.

Or your damp could be actually condensation. This is the only one which would be solved by ventilation solution surely?

Have you had an engineering inspection done to determine the root cause? Once you're sure of that then you can start looking at solutions. No point in putting in a solution to a problem you don't have.

Positive input or demand controlled ventilation could help, but as above, you need to understand the causes as well

This might be a lack of insulation meaning there are cold surfaces where moist air condenses or a rising damp or external damp source, or a lack of ventilation

You absolutely need to understand why the house is damp before you attempt any solution.

It could be lack of ventilation, poor insulation, bad windows, rising damp from the foundations, leaking pipes in a heating system that's constantly topping up, bad roofing issues, the house may be too cold etc etc etc.

thanks for your advise. I didn't get an engineer inspection done I can get this done but where do I go to get this done? In the last 3 yrs I changed the windows and insulated the walls but the damp is still causing a problem. So it definitely makes sense to get an inspection by an engineer.

I moved into an older house last year and had a good experience with Damprite which was recommended to me by my engineer- http://www.damprite.ie/

Have no connection with the company apart from being a customer.
