Damp Proofing

Condensation in 1920s terraced property

Anonymous user 03/03/2024 - 2.59 PM

We have lived in our home for the past 3 years and have had persistent problems with condensation in our bedroom as well as several other walls throughout the property. There is black spot mould on on our walls and parts of the ceiling nearest to the window (possibly due to poorly installed loft insulation?) We have been told that retro fitting a new wall layer and also a false ceiling will solve this issue but I fail to see how this would work on evacuating the moisture from the air. I know there are probably several causes to our issues and therefore would probably require several fixes. Any help and advice would be greatly appreciated. A little more info on our home in Liverpool - we have double glazing without trickle vents, we don't dry our clothes on radiators, we have an extraction fan in the bathroom and always use this. Cheers

Could be a number of solutions, it will probably be a solid wall construction built using lime mortar, if it has been re-pointed with cement this can cause dampness as your wall can't breathe, the felt on your roof at the guttering may be eroded allowing water ingress into the brick work, fitting trickle vents in the windows will help. Your loft insulation may need upgrading. You don't say if there are any chimneys and if they are in use or vented. The solution you have been given is in reality to cover up the problem rather them solve it. Hope this helps, good luck Alex

Hi there You are correct there will still be moisture in the property so better air ventilation will help, better insulation in the loft which ever way you can access it and thermal boards polystyrene backed plasterboard dot and dabbed on to the exterior walls then skimmed. This helps because it raises the temperature of wall so that if moisture goes to the wall it will not reach its dew point where turns to water, which the mould then feeds off. When decorating only use a matt paint so the plaster can still breathe. Regards Joseph

Hmmmm, you mention you always use the extractor fan. Does it have an over run? Is it humidistat control? Do you have one in the kitchen? It may be more cost effective to install a humidistat controlled extract fan in bathroom and kitchen (the sources of moisture) at around £300 each as opposed to a p.i.v. system which is nearer the £900 mark.
