Wet and Dry Rot Specialists

As wet and dry rot specialists we can help you find out what is causing this rot problem in your home. We will look for the reason why you house has developed the right conditions for this type of outbreak under the property.

When it comes to understanding fungal decay in your homes most people will probably notice the effects of it first such as a spongy wooden floorboard joist in one area of the room or that continuous damp musky odour you can’t seem to get rid of. This will be before you put your foot through the rotten floorboards and realise how bad the problem really is and how much damaged has been caused by not detecting it earlier due to some old building fault.

Wet and Dry Rot Treatment

Our wet and dry rot treatment solutions will help cure that fungal infection and stop the rot. Where the problem has caused too much damage we are able to replace those timbers. We can replace floor joists and floorboards using reclaimed Victorian timber products that will match your current flooring. If the attack is dry rot and has caused too much damage to the plaster work, which also can be replaced with a breathable sand and lime plaster product.

Our wet and dry rot treatment is safe to apply on structural timber in your home and stop the fungal spores spreading to other areas of your sub floor space.

Wet and Dry Rot Survey

Also the lack of airbricks or blocked airbricks is essential to ventilate the sub floor area as this will effectively force moisture out leaving timbers and the properties oversite dry.

Have you had a homebuyers report or may be found wet or dry rot somewhere in your property such as the joists in the floorboards in the lounge. Then the best way to diagnosis any fungus is to have a wet and dry rot survey.

So if rot is affecting your home the first thing you need to do is identify the type of damp you’re dealing with. The one thing that all fungi have in common is that they need moisture content over 20%.

We can quickly write to you with a full report and identify which fungal species has attacked your property’s timbers and recommend a wet and dry rot treatment to eradicate it quickly and safely.

So don’t be damp Be Dri, gives us a call and arrange a rot survey today we can help you.

Wet and Dry Rot Types

Timber can be affected by two types of rot theses are known as wet rot and dry rot. Lots of people have heard of these types of rot but do not understand what causes them and the long term effect on your home.

Dry Rot

Dry rot is the one everyone dreads because it travels so far before being noticed causing damage behind plastered walls and working its way through old sand and lime mortar into other rooms as well. Wet rot is the most common and the one that home buyers will find in their survey report if they are unlucky. Of the two wet rot although less damaging than dry rot if left to its own devices will consume large amounts of timber.

Wet Rot

It can be hard to tell wet rot and dry rot apart in the early stages. But all rots do thrive in damp conditions, so by eliminating the source of damp they will die off. Houses with poor ventilation will cause the right conditions as it will stop damp air from evaporating harmlessly away.

Most ground floors are made from floorboards laid over wooden joists, which are potentially susceptible to damp and attacks of rot.

Features of Fungi

Fungi are plants, members of the vegetable kingdom, and this is the group to which the organisms responsible for the particular decay of wood called Dry rot and cellar fungus belongs. The fungi are primitive in their development and must have evolved very early on from the most primitive of the green plants, algae and this very early in the history of living matter on earth. The fungi have developed to form a group of organisms of the greatest importance and something like 90,000 different species are known, although only 5000 species of green algae have so far been identified.

Green plants and photosynthesis

How Fungi Grow

Green plants contain a complex substance called chlorophyll. This is contained in small ovoid bodies called chloroplasts which move about in the cell sap. Carbon dioxide which is a colourless gas occurring to the extent of 0.03% by volume in the atmosphere is absorbed by the plant and with water absorbed by the roots and aid the chlorophyll and energy derived from sun light, simple carbohydrate substances (that is substances containing carbon, hydrogen and oxygen) are built up by synthesis.

More complex organic substances are built up by the plant from these simple carbohydrates. One of the more complex carbohydrates is cellulose which goes to form the walls of the box like ‘cells’ of which plants are composed. Cellulose consists of relatively large molecules but nevertheless is built up from relatively simple units of glucose. This is by far the most important process which takes place on earth, as all animals are directly or indirectly dependent upon green plants.

With the possible exception of man the fungi are surely the next most important group because they bring about the destruction of green plants and bring other nutrient materials decomposing them back into the earth. Besides the chemical elements already mentioned which are present in the tissue of plants a number of mineral substances are also present although in much smaller quantities.

These mineral salts are soluble in water and are absorbed by the plants through the root system. These salts are present only in small amounts in the soil and so unless the plants died and the nutrients dispersed in the soil through the action of decaying life would struggle to thrive.

How Wet and Dry Rot Fungi Feed

Fungi are plants without chlorophyll and therefore must obtain their nourishment from other organic matter. If they obtain their nourishment from living organisms they are known as parasites. A large number of species of fungi are known to be living a special relationship with animals or plants in which they are mutually beneficial.

This special relationship is known as a symbiosis; the individual partners are known as the symbionts. An example is the yeast like fungi habituating the gut of the larva of the wood bring beetle common furniture beetle (Anobium punctatum). The yeast like cells plays a part in the nutrition of the larva.

The yeast like fungal cells is maintained in an environment in the gut  of the larva which is beneficial to them. The other group of fungi, those which obtain their nourishment from dead organic matter are known as saprophytes and it is this group that the wood rotting fungi with which we are interested in and dry rot and the cellar fungus and others belong. These types of fungi obtain their nourishment from the timber in your homes.

Wet rot (Brown rot)

 Wet rot caused due to extremely wet conditions wood does not like being kept in wet, damp and dark areas if not treated. It is a natural product that will break down quite quickly if left to the elements so if you add a fungus it will be consumed until there is nothing left.

The most common form of wet rot is the cellar fungus (Coniophora puteana and C. marmorata) and will attack softwoods (pine) and oak (hardwoods).

The fungus causes the wood to darken with cracks along and across the grain as the wood rots. Where conditions cause drying on the surface, an apparently sound thin skin of timber often remains which may crack longitudinally as the decay progresses underneath.

Where the fungal attack is quite new it usually shows yellow discolouration on the surface. The Mycelium is only present where there is high humidity and rarely without brown strands. Cream to brownish in colour and often off white if completely left in the dark with no light source. It might also spread sketchily over damp plaster or brickwork. The strands are thin and usually brown or black although they are yellow when young. Fruit bodies are rare in buildings but if found they will be thin and lying flat on the wood. Cellar fungus has small irregular lumps and is olive green to olive brown with cream margins can be paler when young.

Dry rot (Brown Rot)

Dry rot spores are present in the atmosphere just like grass and tree pollen just waiting to settle on some poor soul. So if your home has a damp issue then these fungal spores will settle and start to increase rapidly. Given time the fungus will consume the timber it started from and will continue to give off a mouldy fusty smell.

When the airborne spores settle on damp timber, they will then send out thin grey spider web root strands that will spread across the surface of the wood. The dry rot fungus feeds by extracting the moisture from the wood this action will make the timber dry, crumbly and structurally inadequate.

These fungal root strands (hyphae) will quickly multiply in damp conditions and rapidly become matted, surrounding the wood. They then adopt the appearance of cotton wool turning grey (Mycelium) with lilac tinges and yellow patches. From this they produce (strands) which are white to grey and branch out sometimes as thick as a pencil, they are brittle when dry.

And in their final phase transforming into a mature, pancake shaped, rust coloured (fruit body) which emits millions of spores that drift off into the air and around you house if not detected yet.

Dry rot (Serpula Lacrymans) is often misdiagnosed because its appearance is constantly changing. It can sometimes look like other forms of rot, depending on what lifecycle stage it is at.

Brown and White Rot Fungus

Brown and White Rot

Because people are so familiar with the terms wet rot and dry rot, todays experts consider this to simple. Fungal decay to timber can now be more accurately categorized as brown and white. Brown rot includes all types of dry rot and its close relative cellar fungus. White rot includes most types of wet rot but not all.

The key difference is in their methods of attack that destroy different parts of the timber.

Brown rots work by removing cellulose from the wood, leaving behind a brown matrix of lignin (lignin is a chemical found in plant cell walls that makes them rigid and woody).

White rots also consume the lignin, leaving behind blanched looking decayed wood with an anaemic tinge. Despite this, brown is actually far more destructive than white.
