Damp Prevention

Where ever possible, when it comes to damp, prevention is better than cure. In order to prevent damp it pays to maintain your home, this means responding to any damage to your property such as leaks, issues with guttering or external pipes, quickly.

It’s surprising how neglecting to repair something small can lead to a huge expense. Penetrating damp can be caused by damage to a guttering or the result of a pipe that has burst.

Another type of damp

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 DPC (Damp Proofing Course.)

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:

  • Use an electronic moisture meter (obtained from most DIY shops) to check the moisture levels in the walls twice a year.
  • Dig away any soil that is resting directly against the property to leave a gap and prevent moisture build-up.

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.

Condensation dampness

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 problem is, black mould can appear almost anywhere in the home.

Preventing condensation dampness

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 condensation control unit fitted. EnviroVent has a wide range of eco-friendly ventilation systems including the Mr Venty Range of condensation control units. The units are quick and easy to fit, they deliver fresh, filtered air into the home from a central position (hall, loft or landing), there is even a Mr Venty condensation control unit specially designed for apartments.
