Rising damp is harder to prevent and it can occur in a modern home, however, it is normally found in older properties as homes built from 1875 onwards have been built with a damp proofing course, known as DPC.
According to the English House Condition Survey, conducted in 1996, 11% of dwellings built between 1900 and 1918 are affected by rising damp with 1% of houses built after 1956 also affected.
If the damp proofing in the property has been ‘bridged’, for example, the exterior ground level has risen above the interior level; problems with rising damp are more likely to occur.
The following will help prevent rising damp:
Rising damp is easy to spot but it is often confused with condensation damp. Condensation damp is easier to remedy and not as expensive to fix.
Poor or inadequate ventilation is the root cause of condensation damp, prolonged condensation damp leads to the appearance of black mould on walls, doors, ceilings and around window frames.
Depending on how bad the condensation problem is, black mould can appear almost anywhere in the home.
You can prevent condensation damp by ensuring that your home is correctly ventilated.
If you are in the process of having any home improvements such as triple glazing or cavity wall insulation installed, you need to be aware that as you ‘seal up’ your property to conserve energy, you may be reducing the ventilation.
Once the ventilation inside the property is prohibited or restricted your home could become vulnerable to condensation and mould.
Check that all of your extract fans are in working order and not clogged up; fans that are clogged up won’t perform as efficiently as they should.
One way to prevent condensation damp is to have a whole house ventilation system fitted in your loft space or hallway to ventilate your home.
The ventilation system delivers fresh, filtered, clean air into the home from a central position and reduces the moisture levels within the home.
