| Not just old houses are at risk from fungal decay;
but any timber with a moisture content above 20% is at risk of fungal
infestation and therefore timber rot.
Different Fungi prefer different ranges of temperature, food
source, moisture content and other conditions. It also creates ideal conditions
for borer and termite attack.
Did you know that over %70 of residences are affected by fungi?
Sometimes very simple symptoms - mould on your walls, shoes or
leather items in your cupboards or "just a musty smell" is a dead give away.
Other signs of moisture or ventilation problems are :
-
timber in contact with floor has deteriorated;
-
condensation, mould or fungi on floor or surface areas;
-
paint work peeling or flaking;
-
floor tiles or lino lifting;
-
cupping, boring or warping of floor timbers.
We have had customers who have even thought of moving home to get
away from this problem and did not realize the cause. Our expert advice and
technical knowledge of ventilation (in this case forced air circulation) has
quickly corrected this problem.
Fungus (plural: fungi) is basically a plant which feeds on
organic matter (eg. mushrooms are fungi). They don not contain chlorophyll
which produce the green colour in plants. Fungi require environments with
atleast 20% moisture to flourish.
Moulds
Similar to what you may see on bread. Like all fungi, can cause
health problems by exposure to the spores.
Sap stain fungi
Stain fungi, so called because of the stain they produce in the
timber when feeding on the sugars in the cells of the wood. Often blue tinge.
Neither cause damage to the structural strength of the timbers as they feed on
cell content only.
Decay Fungi
Generally requiring a high moisture content of 24%, this problem
does cause damage to the structural strength of timber, often resulting in
crumbling and loss of weight of the timber. This fungi feeds on lignin (glue)
and/or the cellulose cell walls
of the timber as well as the cell contents
Brown rot
Brown rot, sometimes also known as "cubic" rot, as it not only
breaks into large lumps called cubes, but when exposed to the atmosphere it
oxidises into a brown colour.
White rot
Here the exposed cellulose and lignin leave the timber white,
fibrous and decayed.
