Since moving to our property a few years ago, we've had a damp cellar and very high humidity in the house. This causes a lot of condensation problems and even after changing our lifestyle such as drying clothing at launderettes, using extractors and dehumidifiers and plenty of ventilation, our humidity levels stay stubbornly high.
But recently, whilst accessing the cellar, I've spotted a damp in our coal room floor hidden under a workbench - This is an area I've normally never checked.
The damp patch is:
- Approx 1ft by 1ft in size
Clean/rain water mixed with dirt from cellar - no smells at all
Not touching the edges of the walls and seems to be coming from the ground up
I've already checked:
- Roof gutting and downspouts - All clear and not overflowing
Gulleys around the house - Camera thrown in to check for damage or any sign of blockage - Nothing at all
I'm not sure how important this is, but I would like to add though that the neighbour has what seems to be like a storm drainage with a large manhole cover. I have lifted this cover and it seems to be clear with water running down it. However this is running exactly parallel to where our puddle is. I'm suspecting that either we are getting ground water or we have an old disused storm drain which is causing all these issues. Could anyone advise please?
