MOULD INDOORS

Mould has roots that penetrates different constructions- Air, damp and nutrition is the most important prerequisite. Sometimes moisture content as low as 40 -60% is enough for multiplication and growth.

Many sorts produce hundreds of toxins -mycotoxins- and there are many very dangerous sorts of mould and fungus. There can be toxins even if no spores are found.

Many of them cause serious illnesses -asthma, dry cough, and pneumonia, problems in upper respiratory organs, sinusitis, skin rash, disorientation and nose-bleeds.

Many species are poisonous and several mycotoxins are carcinogenic.

Heavy exposure can lead to considerably more dangerous illnesses.

  • Microbic growth* -mould, rot, sap stain and bacteria.

  • Rot damages -damages that affects solidity

  • Visible damp -free water surfaces or visible moisture

  • Smell -smell of microbic growth

  • More causes -both visible damp and microbic growth

MOISTURE

If the space is damp -and side walls in crawl spaces are wet or damp -then this can be a pre-stage for future damages.

Visible damp can be a consequence of water from outside that has seeped in under the side walls.

It can even be caused by condensate on ground walls and under the joint system.

Visible damp exists within older crawl spaces. Many times damp protection is missing on the outside and the system of joints have been tightened -with decreased temperature and condensate as a consequence.

MICROBIC GROWTH

If there are discolouring or visible affections by mould under the system of joints, this is a sign of the foundation is to damp.

The microbic growth is considerably more common in joint systems in new houses. This is because most of the construction material in the joint system is different to that in older houses.

SMELL

If a microbic smell -as an earth cellar or of mould- is detected in the joint system, the cause should be examined. The damage is a fact and actions must be taken.

This is due to the relative moisture content is so high -during parts of the year- that growth of micro organisms can start.

These organisms create smells over time. Regardless if it the smells come from the ground or the joint system, the source of this must be examined and actions must be taken, else there is an imminent risk of the smell getting into the living area.

ROT DAMAGES

The number of rot damages is larger in older houses because the rot fungus normally takes longer time to develop than a mould fungus.

When a joint system has changing moisture content depending on the time of year, the development of a rot fungus takes long time.

Normally it is during the late summer and the autumn the rot fungus have sufficient moisture to grow. For the rest of the year they are hibernating.

CAUSES

The combination of several causes increases with the building's age.This is expected, since the damages are getting worse over time.

One example is when it begins with damp that leads to microbic growth. If it is adequate damp during long time it ends with rot damage.
