How fast does wet rot spread

It should be noted that very slight variations on the above figures have been reported. So can dry rot spread? It also has some limited ability to wet up dry wood, but again, this will only occur where there are very humid stagnant conditions or where it may be trapped between impervious materials where water cannot evaporate.

Dry rot may also spread over onto other materials such as carpets and fabrics if in contact with dampness. However, unless these materials are cellulose based it is unlikely to cause any damage although some discolouration may occur. So, in practice decay by dry rot tends to be restricted to damp, unventilated areas and often remains unnoticed until the damage is at an advanced state; frequently it can go undetected for many years. This also occurs where large dimensioned timbers are in direct contact with damp masonry but remain well ventilated in which case the decay only develops within the interior of the member, the outer surface remaining sound.

Under very humid, stagnant conditions white cotton wool-like aerial mycelium is produced. In extremely humid conditions droplets of water form on the growth. In less humid conditions the growth tends to form a silky-grey skin, often tinged with patches of lilac and yellow colouration. Unlike many other wood destroying fungi dry rot can readily grow over and through porous masonry provided that there is a nutritional source wood from which it can spread; this ability allows the spread of the fungus from one area to another.

This generally only occurs to any significant level where the masonry is damp either via severe sources of water ingress or rising damp, etc.. These are resistant to desiccation and carry nutrients from the food source to the growing tips of the fungus when the organism is growing through or over nutritionally inert materials, eg, masonry, soil.

They support the spread of the growth. However, without a source of food growth is terminated. When the decay is advanced the shrinkage causes the wood to split in a cuboidal manner this is typical of a number of wood destroying fungi , and it is therefore not always easy to distinguish between dry rot and other fungi wet rot — brown rots in the absence of fungal growth.

Should infected timbers dry out or the food source be removed the growth will cease but, depending on conditions, it can take considerably longer for the fungus to die. However, this period may be prolonged at lower temperatures. If infected wood is removed then the growth is very limited and quickly terminated, but the growth can remain viable in damp masonry at low temperature eg, 7 o C for up to 9 years, and up to 1 year at ambient temperatures.

Should new, untreated or inadequately treated wood be put back into direct contact with damp infected masonry, even though the original decayed wood had been removed, then fungal growth may start and spread into the new wood so initiating further decay. In most cases, the optimum conditions for growth and decay of timber have been derived under carefully controlled laboratory conditions.

In practice, however, it is highly unlikely that such optimum conditions would be present, or at least for any length of time. The procedures for the control and eradication of a dry rot infection are given in Building Research Establishment Digest and British Wood Preserving Association Code of Practice for Remedial Treatment; where remedial works are envisaged then the work should be undertaken in strict accordance with the principals and instructions given within the above publications.

Basically, the control of all rots is a matter of good building practice but it also requires a thorough understanding of the nature of this particular organism. At Timberwise, we first undertake the fundamental procedure to control and eliminate the rot and that is to eliminate the source of water, to remove infected timber if the rot is active, and propagate and maintain drying conditions.

Without either food or water the fungus cannot grow and will eventually die. We regard ancillary chemical measures as secondary to the above in the control of dry rot. It should also be considered that chemical treatment of timber and masonry must be capable of resisting the rot for at least the period of drying down; this could take several years in some cases otherwise it will be of little value.

It is these factors which Timberwise fully appreciates. As we have explained this article, dry rot can spread at your property so it is important to deal with it quickly.

Like most property related problems, the longer the problem has persisted without being acted upon, the worse the problem tends to be - much the same can be said for wet rot.

If wet rot is spotted in its early stages, it may be the case that only small areas of timber need to be treated, in more serious cases where the rot has been able to spread across timber, replacement of entire timbers may be necessary.

And knowing how long it takes for wood to start rotting can help you address the issue faster.

We often speak of wood rot as a singular phenomenon, but there are actually two major types of rot that affect wood: dry rot and wet rot. Dry rot is regarded as the more problematic of the two types because of its less confined reign and ability to hide its presence for longer than wet rot.

The speed and spread of rot can vary widely. Lab experiments have recorded that dry rot spores can germinate approximately seven to ten days after the wood has become damp enough. Older spores can take longer to germinate. As mentioned earlier, though, it can take a long while for signs of dry rot to appear after germination. That said, wet rot can only spread to those areas damp enough to accommodate it. So, if you notice wet rot, you can mitigate it by removing any moisture.
