Types of Damp and Condensation
Damp and condensation can blight any home, take a look at this guide on what type of damp you are suffering from and how to banish for good..
The most common forms of damp are Condensation, penetrative damp and rising damp. Treating them can vary massively and so can the costs so it is worthwhile investigating what you are suffering from to keep the costs down for the repair works
Penetrative damp is where there is water ingress to inside of the property through the transference of water from the outside to the inside skin of the wall and moves through the wall rather than upwards.
Water can penetrate through walls for a variety of reasons, most commonly from failed cavity wall insulation, leaking roof along the top of the wall, faulty guttering or failed render.
The damp is seen in the form of wet patches on the wall and the repair work can be localised to this area to establish the reason by looking outside in this area to see what is failing.
Repair costs to guttering is cheap and easy to remedy, if you have a cavity wall constructed house however, it may be necessary to remove the cavity insulation from the property if it has failed
This is the most common form of damp within homes in Britain. Condensation is formed from warm moist air condensing on a cold surface and is seen in the form of black mould spores on walls and window frames which can be hazardous to health through respiratory problems.
There can be many reasons for condensation forming but most commonly it can be brought back to insufficient ventilation in a property.
To complete a check of your homes, it is worth looking at the two areas which produce the most moisture in the homes in the bathroom and the kitchen where extractor fan ventilation is imperative to remove the warm moist air before the condensation can form.
If you still suffer from condensation around windows, it is beneficial to add extra ventilation into rooms affected. One source of moisture which is controllable is the ceasing of drying clothes on radiators with the home.
Rising damp is seen in the form of wet walls near ground level where floors and walls absorb water from the ground and there isn’t a control measure in place to stop the water from rising.
Newer homes are built with a damp proof course installed 150mm from the ground level and is embedded into the wall to stop and damp from entering the homes.
Older homes, typically built with solid walls however won’t have a damp proof course installed and can lead to water ingress.
Once the damp has set in, it will leave to the damage of interior decoration like peeling wall paper and white powdery salt deposits forming on the walls.
If you are suffering from rising damp the remedies may be beyond the skill set of a DIYer and advise from a specialist damp proofing company should be soughtPosted on: May 25, 2018, by : cwip_admin
