    We like wood. We love its look, feel, versatility, and workability. Wood rots, despite being great. Rotting wood must be properly handled. How can you tell if wood is rotting, and what should you do?

    Wood and timbers can rot dry or wet. Dry rot is caused by a living fungus, while wet rot is caused by high moisture levels. Dry rot is far more serious and is treated by removing infected wood and applying fungicide. Depending on its severity and location, wet rot can be treated by reapplying water-repellent finishes or by replacing the affected wood. Wet rot must be addressed at its source to prevent further problems.

    Wood can degrade despite its strength. Poorly maintained wood attracts pests and fungi. Rot is a common problem in wooden features, and the sooner you find it, the easier it is to fix. How to spot rotted wood.

    At Hitch Property Constructions, we offer timber repairs work from simple timber repair to almost new structures, renovations, and extensions.

    How to Identify the Three Types of Wood Rot

    Rotted Wood

    Wood + Water = Decay (rot)

    It's just a simple equation, but it has the potential to do a lot of harm. Wood rot can destroy a deck much more quickly than almost any other problem, second only to termites. In order to minimise the amount of damage caused by wood rot, it is imperative that the problem be discovered at an early stage and treated as soon as humanly possible.

    There are three distinct types of decay that can affect wood. If you are able to correctly identify the rot, it will be easier for you to determine the most effective course of action to take in order to fix the problem.

    Brown Rot

    White Rot

    • Parts of Wood it Damages Cellulose, hemicelluloses and lignin.
    • How it Affects Wood: Significant strength loss
    • Moisture Content Conducive to Decay: 20%+
    • Visible Signs: This rot gets its name because affected wood will get white spots where rotted. It can range from whitish to grey or yellowish. Wood with white-rot will feel spongy.

    Soft Rot

    • Parts of Wood it Damages Cellulose, hemicelluloses and lignin.
    • How it Affects Wood: Significant strength loss, but slower degradation than the other two types of rot.
    • Moisture Content Conducive to Decay: 20%+
    • Visible Signs: This is the rarest type of wood rot. The cavities it forms are within the wood. However, you may see cracking and discolouration similar to brown rot.

    Dry rot and wet rot

    Both wet and dry rot can affect wooden surfaces, but dry rot is the more common of the two. The infestation of a living fungus is usually what causes dry rot, which is considered to be the most damaging type of decay to your timber (sounds yucky, we know). On the other hand, wet rot is a form of natural decay that occurs in wood as a consequence of the amount of moisture present in the atmosphere around it. Since there is a difference in the treatment for wet rot and dry rot, the first step in finding a solution to the problem is to determine which kind of rot you are dealing with.

    Common signs of dry rot:

    • Cotton wool-like substance on timber
    • Mushroom-like fungus on the surface (often rusty or yellowish)
    • Spore dust around the surrounding area
    • Warped, dry, split, crumbling, or shrunken wood
    • A musty smell

    Common signs of wet rot (usually found in timber that gets a lot of moisture- near water or close to the ground):

    • Wood appears darker in rotting areas
    • Wood is easy to penetrate
    • Wood is soft and spongy
    • A black fungus may be visible

    How to treat wood rot

    Different types of rot require different treatments. Depending on the severity and location of your rot (i.e. if your timber is structural), get professional help. Experts can help you find the best solution in these situations.

    Whether wet or dry, affected wood must be removed and replaced with healthy, pre-treated wood. A fungicide is used to stop rot and save surrounding wood. You must also take preventative measures to protect your wood. This means keeping wood dry and waterproofing it.

    Identifying Dry Rot

    Step 1

    When it is in its earliest stages, dry rot will appear on brickwork and timber as cottony sheets of an off-white colour. If it were to be put in direct sunlight, it might take on a yellowish hue.

    Step 2

    Some mushroom-like bodies may grow over surfaces and finishes, such as plaster or paint, that are concealing dry-rotting timber. These surfaces and finishes could be anything from drywall to wallpaper. They are frequently the first obvious signs that dry rot has set in.

    Step 3

    Examine the timbers to ensure that there are no long, deep cracks that run across the grain. It's possible that the off-white fibres of the fungus are visible in these cracks as well.

    Step 4

    When working with wood that you suspect may have dry rot, it is best to apply direct pressure whenever possible. Timber decaying from dry rot will buckle under pressure, often crumbling under even slight touches.

    Identifying Wet Rot

    Step 1

    Check for wet rot in areas that are typically susceptible to moisture, such as those that may be exposed to the most moisture or that are closest to the ground or that are located in other areas where water collects.

    Step 2

    Paint and finishes can give the appearance of being in good condition while actually hiding rotting wood underneath. When pressing into the timber, experienced builders and experienced do-it-yourselfers may use a thin-bladed knife and apply only very slight pressure to achieve the desired effect. It is not necessary for the knife to penetrate very deeply at all. A telltale sign of rot is deep penetration.

    Step 3

    Try your hand at the wood in question. Even with finishes and paint, wood that has been affected by wet rot will have a spongy texture, and it will appear darker than wood that has not been affected by rot.

    Wet vs. Dry Rot

    To begin, it is important to differentiate between the two primary forms of rot that can affect your wood: wet rot and dry rot. As its name suggests, wet rot refers to a species of fungus that attacks damp wood in addition to other moist materials such as carpets and plaster. Dry rot has the ability to rapidly spread and will eat away at wood from the inside out.

    While both forms of rot are problematic, dry rot is the more severe of the two due to its rate and strength of spread. Wet rot spreads much more gradually because it needs an existing source of moisture to grow, meaning it won’t spread beyond damp areas.

    Spotting Signs of Wet Rot

    To the inexperienced eye, wet and dry rot can be difficult to tell apart, but there are some telltale differences between these frustrating fungi. In order to identify wet rot, you’ll want to focus on the wood’s colour, texture, shape and size of damage (i.e. fracturing), and smell. More specifically, common wet rot signs include:

    • Softened texture (spongy and easy to penetrate with a pointed object)
    • Darkened appearance (one area might appear darker than the rest)
    • Shrinkage/warping
    • The musty, earthy scent
    • Cracks and crumbles
    • Localised fungus growth
    • Chipping paint (i.e. wood deck paint)

    You can usually determine whether or not something has wet rot simply by looking in damp places, as this type of rot thrives in these conditions. For instance, wet rot is more likely to occur in areas such as basements, attics, and roofs, as well as other locations that have experienced high levels of moisture (though dry rot may also occur in these places).

    Spotting Signs of Dry Rot

    Dry rot is perhaps even more difficult to pinpoint than wet rot because it tends to exhibit more obvious signs later in its lifecycle. That said, those experienced with wood rot, carpentry, deck repairs, etc. can usually find dry rot if it’s there. These signs include:

    • The appearance of fruiting bodies (mushroom-like, pancake-shaped, rust-coloured, porous)
    • Spore dust on wood (usually red and near fruiting bodies)
    • The spread of white mycelium across wood (fine, fluffy strands)
    • Yellow-white-grey-ish “skin” overlapping the wood in patches
    • Damp, musty, mushroom-like scent

    What to Do About Rotted Wood?

    First, address the source of the rot in your wooden features (usually a source of moisture). After that, you can kill the fungus and make repairs, or remove and replace the wood. Best option depends on rot's depth and spread. If wet or dry rot has engulfed a large portion of your wood, replace it. If you catch the rot early and it's isolated, a fungicide can usually stop it. After killing the fungi, make repairs, reapply deck stain or paint, and/or apply wet rot wood hardeners.

    Common Indicators of Wood Rot

    Some home problems are highly visible, reminding you they need repair. Wood rot often grows and feeds hidden. Undiagnosed wood rot can affect your health and home. Wood rot can affect a building's structural integrity in rare cases.

    Due to the risks of untreated wood rot, it's important for homeowners to recognise all stages. If you live in a humid area, check for wood rot at least once a year.

    If you notice any of the following six signs, consult a wood rot expert immediately.

    Damaged or Decaying Timber

    When looking for signs of wood rot, a softwood is one of the most common and reliable indicators that you will find. If the wood is spongy to the touch or brittle and crumbly, this is likely an indication that it has been damaged or is decaying as a result of rot. It is highly likely that this section of the timber will need to be removed in order to prevent the rot from spreading further. A section of the wood that appears shrunken or darkened is another common sign that the wood has been damaged.

    Large Patches of Spore Dust

    Dry rot spores appear at many properties, sometimes without accompanying rot. However, areas of spore dust that are both large and concentrated should raise some concerns. If you discover large areas covered in fine dust that is orange, rust red, or brown in colour, you should seek the assistance of a trained professional in order to remove the spores.

    Fine Strands (Hyphae) on Timber

    After a certain point in the progression of the wood rot, the rot spores will develop into thin grey strands that are referred to as hyphae. These strands have the appearance of spider webs and work by drawing moisture out of the surrounding wood, which causes the wood to deteriorate over time.

    Grey or White, Wool-Like Cushions

    Dry rot, which is distinct from mould and mildew, can give rise to a substance known as white mycelium. Mold and mildew are not the same thing as wood rot. The appearance of white mycelium is comparable to that of the white mould that can be found on stale food. When there is a need for the rot to spread, these cushions that are similar to wool and cotton are produced. The mycelium cushions can be found in a wide range of colours, from stark white to charcoal.

    Mushroom-Like Fruiting Bodies

    The fruiting bodies, which can resemble either mushrooms or pancakes, are extremely difficult to miss and are an indication of a problem that has been present for a considerable amount of time. The surfaces of these bodies are covered in pores of a wide variety. The presence of these large pores is evidence that the rot has extracted as much food as it can from the wood and is now in the process of producing new spores to begin a new cycle.

    Damp, Musty Smell

    The musty and clammy odour that is characteristic of rot in general is produced by wood rot specifically. This odour is present whenever active rot is present; therefore, if you start to notice the odour in your home, it is prudent to look for the signs that were discussed above in order to locate the source of the odour.

    Where to Look

    There are a few key areas to check for wood rot. Wood can't rot if it's not wet, so wood exposed to humidity, rain, or other water sources is at risk. If you see cracked or chipped paint, check the wood underneath for moisture.

    If you see any of the above signs, call a wood restoration expert. The sooner the problem is fixed, the easier and faster it will be.

    Ways to Prevent Wood Rot

    Keep it painted.

    Painting your home regularly is the simplest way to prevent water from getting inside. A good layer of protective paint can help the surfaces of your home resist the accumulation of dirt and water. Even though it could get wet, the paint prevents water and fungus from getting through to the underlying wood and damaging it.

    No standing water.

    If there is any area of your home that is left with standing water after a storm, then the likelihood of rot in that area is significantly increased. Water that has been left to pool will eventually seep through any joints or cracks in the paint and seep into the wood, creating the ideal conditions for rot to set in. Redesign these components so that they can easily shed water when it rains.

    Allow for air.

    Good airflow helps things dry faster, which reduces rot. Trim shrubs and trees from your house to allow airflow. Wet shrubs against house siding cause rot.

    You're miles ahead of us if you can stay dry. Rot is caused by a fungus, but keeping your house's exterior dry will stop it. Prevention is easier than cure.

    To keep wood healthy and structurally sound, prevent rot. Use pre-treated wood, hire pressure washing services to clean your exterior wooden features once or twice a year, and apply deck stain to your wooden deck or patio every 2-3 years to seal the wood's pores and protect it from moisture, pests, and fungi.

    Rot is different from mould. Mould and mildew can be removed from decking with cleaners. Rot destroys wood's structure and strength.

    Mold and mildew indicate water issues. It can also make wood rot-prone.

    Wood rot becomes more severe and widespread if left untreated. Damage increases repair costs. If surface signs appear, wood damage is likely severe. If you suspect wood decay, inspect the deck, including under the decking. Replace damaged wood as soon as possible.

    FAQs About Wood Rot

    The best product to use to treat and kill Dry Rot in masonry is Boron powder dissolved in water. You can brush the Boron solution onto the affected masonry or spray it on depending on the size of the affected area and your preference.

    Wet rot happens because of moisture, and it makes the wood softer. However, it does not spread. Dry rot, on the other hand, spreads, and it could be very dangerous if untreated. To identify either of these, you have to know their signs.

    After that, the dry rot spores will start to appear and develop into the fungus; from there, the fungus can spread throughout your house to other wooden structures.

    Despite its name, dry rot only affects damp timber and structural materials. This can be caused by high levels of condensation in your home. Water entering your home from an external source, for example as rising damp, also causes dry rot.

    Wet rot is more likely to smell than dry rot. It has a damp, musty smell that has been described as smelling earthy and like rotting soil.
