    Any homeowner can suffer from home repairs. Out-of-sight, out-of-mind may lead to disaster with wood rot.

    Wood rot is caused by humidity, fungi, or old age. Sometimes all three combine. This natural decay is enough to make any homeowner panic.

    Building with wood is common. Because of this, it's important to know what wood rot is, how to identify it, and how to treat it.

    Water leaks or plumbing leaks cause wood rot inside walls. Solve this problem before repairing rot. This prevents moisture from damaging new repairs. Dry rot spreads to surrounding wood and attracts insects and other pests, causing even more damage.

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

    What is Wood Rot?

    Wood rot is the deterioration of wood due to the growth of fungi. These fungi eat up the structure and integrity of the wood, leaving it weak and vulnerable.

    Structural Wood Rot

    Why Fix It?

    It can be very frustrating to have to shell out money to replace rotten wood. The vast majority of the wood will always be concealed behind walls or beneath floors and will never be seen. It is in your best interest to fix the problem even if you can't see any evidence of the damage.

    Your Structure Could Fail

    Rot in the floor joists and framing of your home could pose a serious health risk, whereas rot in your outdoor pergola might not be as dangerous. In the event that the wood rot in these areas progresses to the point where it causes structural failure, you might find the furniture from your living room in the basement.

    Your Home Sale

    Wood rot can be detrimental to the resale value of your home, regardless of whether you are currently selling it or might consider doing so in the future. If potential buyers discover that your home does not meet certain safety standards, they will be hesitant to purchase it. Before you put your house up for sale, have it inspected, and if you notice any signs of wood rot, have it fixed as soon as possible.

    It Could Be Affecting Your Health

    The actual fungus that causes wood rot is not dangerous to human health; however, the presence of rot in a structure may indicate a more serious issue. The fungus that causes wood rot is not the only type of fungus that thrives in damp environments; in fact, there may be other, far more dangerous organisms growing alongside it.

    How to Find It

    Finding rot in wood before it completely fails can save you a lot of money in the long run. If you keep an eye out for a few key clues and use your senses, you should have no trouble detecting wood rot.

    Look at the Color

    The colour of wood that is in good health should be fairly consistent. The colour of wood will gradually become darker as it deteriorates due to rot. In order to determine whether or not the wood is headed in the wrong direction, compare it to other pieces that are in good health.

    Check the Texture

    Even if the wood has been painted over and you are unable to see the colour, you can still determine the quality of the wood by feeling the grain. When you touch rotted wood, you will notice that it is noticeably softer than it should be and will have a squishing quality to it. When it dries out, wood that has been rotted will flake and crumble.

    Find a Smell

    It might sound strange, but smelling your wood is actually a straightforward method for determining whether or not it has rot. Rather than having a scent that is reminiscent of nature and the woods, rotten wood will have an odour that is musty and damp.

    Check for Fungi

    The actual fungus that causes wood rot is the most obvious piece of evidence of the presence of the fungus. If you observe any signs of growth, it is possible that you should replace the wood.

    Get it Inspected

    If you notice any of these warning signs, you should have a trained professional examine your home. They will be able to determine the full extent of the damage done as well as the necessary repairs.

    How to Treat It

    After you have established the presence of rotten wood, the steps that follow are straightforward. Even though you might want to cover up the issue with paint, it is imperative that you take the necessary precautions.

    Find the Source of Moisture

    Because of the presence of a moisture source, the fungus that causes wood rot can begin to grow. The process of the wood rotting begins when that moisture penetrates it and stays there. Find out where the moisture is coming from and get it fixed if you want to save your wood and prevent further decay in the future.

    Repair Small Areas

    It is possible to make repairs to an infected area of a structure if the portion of the structure that has rotted wood is only a small portion of the whole. Wood filler should be used to fill in any small holes, while new wood should be used to replace larger sections. Be sure to apply anti-fungi treatment to all of the newly repaired areas as well as the parts that were not replaced.

    Replace the Damage

    If the wood rot reaches a certain point or if it is located in an important structural place, such as a floor joist or beam, it is possible that the entire affected area will need to be removed and replaced. If the stability and strength of the wood have been compromised to the point where it can no longer support weight, you should have professionals replace your damaged wood with new wood that has not been exposed to any hazards.

    Types of Wood Rot Explained

    Brown (Dry) Rot

    This kind of rot develops when the fungus invades the wood and begins to break down the cellulose in it. Because of this, the wood will become drier over time and will lose all of its nutrients. Eventually, the wood will crack and split into what are known as "cubical flakes."

    Brown rot can be called dry rot as well. This is because this type of rot causes the wood to dry out and crumble.

    White (Wet) Rot

    White rot and brown rot both destroy the cellulose in wood, but white rot does so in a different way. White rot, in contrast to brown rot, causes discoloured white spots in the wood and an overall sickly colour. This is because it also affects the lignin.

    The spongy and soft consistency of white rot is the primary factor in its development. In environments with higher moisture content, white rot can also develop. Please be aware that this particular type of rot is the most aggressive, and once it has established itself, the decomposition process moves along very quickly.

    Soft Rot

    The least common of the three, soft rot is almost always found in environments that are inhospitable to the growth of brown or white rot.

    The decomposition process of this type of rot is much more gradual than that of the other types because it begins very deeply within the wood's fibres.

    Manufactured Board Rot

    If manufactured board is allowed to become wet, it can cause damage to the built-ins, floors, siding, walls, and roofs of a building, as well as other areas.

    It is possible for water to penetrate these products and enter the particles or layers, where it will degrade the resins, cause the wood particles to expand, and leave spaces in which additional deterioration can take place.

    Fixing Decayed (Rotted) Wood Using an Epoxy Penetrant and Filler

    In the event that you come across rotten wood while working on projects involving an old house, you have the option of either replacing the damaged wood or repairing it with speciality epoxy penetrants and fillers. These products are also referred to as consolidants. This method is not only quicker, but the fixed wood is also more robust than the initial version.

    For instance, if you are restoring an old window and you start by stripping the wood, you should then paint an epoxy penetrant onto the surface. After being primed and painted, the timber will be completely protected from moisture for a number of years thanks to this treatment, which will also make the wood more durable.

    About Epoxy Consolidants (Penetrants) and Fillers.

    These products repair rotted windows, columns, frames, furniture, structural and decorative wood components. They're useful for hard-to-replace parts due to size, shape, or other factors. Restored objects are often stronger and more durable than the originals.

    Infiltrators. After penetrating, hardens to strengthen, rebuild, and insect-proof wood. Rebuilds rotted windowsills, frames, furniture, boats, columns, floors.

    Epoxy fillers are wood replacement putty. High-strength no-shrink adhesive paste to fill, repair, and replace wood in structures, walls, floors, furniture, sculptures. They're water- and insect-resistant.

    How to Repair Wood Rot in Walls

    Locating the Problem

    Look for wet or soft spots along damaged walls. Mildew or mould on the rotted wall is another sign. Check plaster and drywall for sagging, cracking, and breakage.

    Cut away drywall or plaster to expose rotted wall frames. This improves circulation and visibility, drying the damp area. If there's excess moisture, use a fan to dry the area.

    Using an awl, probe for rot. Water damage to solid pieces may not require replacement. Replace 1/8-inch-deep wood that the probe easily pierces.

    Resetting the Wall

    Before removing or replacing parts, reset the wall. Vertically level the wall to determine if it's plumb. If not, tilt the bubble's top or bottom to centre it. Measure level-to-wall distance. A 1/2-inch measurement in either direction is fine.

    A screw-jack-mounted wooden beam supports the roof or floor above. Raise the jacks until the beams are snug, then raise again to remove the wall's weight.

    Cut 22-1/2-degree angles into 4-by-4-inch posts. Nail them 4-feet from the wall. Screw jacks on angle-cut blocks level the wall. Keep all jacks.

    Replacing the Rot

    Whenever possible, remove rotted boards. Remove rotted boards from unremovable boards. Rotted wood can be cut with a rotary tool and saw blade attachment.

    Cut boards the same thickness and width as rot. Make sure they span the cut section and extend 12 inches above and below. It to the damaged board.

    Cut and instal new boards to match the old ones. Angled framing nails should be used to secure the boards.

    Install hurricane brackets on top and bottom of replaced or repaired pieces to reinforce the wall. This prevents the wall from shifting.

    Finishing the Wall

    Slowly releasing the jacks will allow the wall to gradually adjust to its new position as it moves into place. Slowly lower them at a rate of one turn per hour while keeping an eye out for any new cracks or other signs of stress in the walls and surfaces that are in the surrounding area.

    Plaster or drywall should be replaced over the area that was repaired. Apply drywall patching compound to the seams surrounding the repair and float them. Sand the area that was repaired, and then paint it so that it matches the rest of the wall.

    During the next few weeks, keep a close eye on the area to look for any indications of shifting or new water damage. If you discover new damage, conduct an investigation and make repairs as soon as possible to avoid having to undo your previous work.

    Signs of Wood Rot

    Wood rot can be tricky to identify. Typically, it hides within the wood where it is dark and grows uninterrupted. Don't worry, though!

    There are some telltale signs to look for when you suspect wood rot. Here are a few.

    • Damaged or decaying wood should be the very first indicator that you might find. If the wood is crumbling or feels spongy to the touch, it is probably in the process of decay.
    • Spore dust is a common occurrence in most properties. However, if you see large patches of this dust concentrated in specific areas, this is cause for concern.
    • Hyphae or fine hair-like strands on your wood happen once the spores take root in the wood. These strands are capable of extracting moisture from the air, and they secrete substances that break down wood cellulose fibres (weakening the wood).
    • A damp or musty smell can be one of the most noticeable factors of wood rot. A noticeable smell accompanies all types of active wood rot.

    If you are worried about wood rot impacting an area of your home, contact a professional.

    How to Fix Rotted Wood

    First, assess the damage. Repairing wood rot is possible. If it threatens your home's structural integrity, you should have the affected wood replaced.

    Once you've located the rot, remove it with a chisel or small tool. Then, apply wood hardener or epoxy to the exposed wood.

    Fill the hole with wood filler after the hardener has dried, and shape it with a putty knife. Cure as directed (often overnight). After that, sand the wood to your liking.

    Then. If desired, paint wood. The wood will look perfect after painting.

    Around the House

    Finding out what kind of rot you have is not nearly as important as you might think. Rot is rot. However, white rot weakens the structural integrity of wood more gradually than other types of rot. Infected wood that has white rot can frequently still be used, whereas wood that has brown rot cannot be used once it has become infected. It is possible for even a negligible amount of it to have a sizeable impact on the wood's tensile strength.

    Borates come from the mineral boron.

    Before repairing and replacing wood, assess the damage. Use a screwdriver or awl.

    Before repairs, remove as much rotten wood as possible. In structural wood — columns, beams, girders — it's important to cut back to sound wood; if possible, the cut should be made one foot beyond the last rot. As much rotten wood as possible should be removed from window trim.

    Replace structural wood with pressure-treated lumber and keep it away from old wood if possible. For repairs in hard-to-maintain areas or exposed wood, treat existing wood.

    Borates have long been used to treat and stop rots. They're water-based, nontoxic, and long-lasting. Water-based stains use wood's moisture as a carrier. Borates remain in dry wood. Borates move through wet wood. They kill fungi and protect wood from future infections.

    Borate products include Bora-Care, Guardian, Jecta, Tim-bor, Shell-Guard, and IMPEL Rods. All three protect wood and wood-foam composites from fungi and insects (more about these in The Trouble with Termites). Some are sprayed or painted. Tim-bor is a cloud of dust that you inject into cracks. As the name implies, IMPEL Rods fit into wood holes.

    Follow the label's instructions for mixing and applying the product.

    Spending money on your home's structure will preserve its value more than new countertops or a wall hanging.

    FAQs About Wood Rot

    Look for signs of wood damage around the home. This comes in many forms: discoloration, shrunken size, cracks, and splintering. As rotting progresses, it breaks down the cellulose in the wood. This causes the wood to become soft and dark in color; it also gets smaller in size as the cellulose is consumed.

    How do you find decaying wood? Wood decay softens surfaces, so they usually feel spongy to the touch. It also darkens timber and may feel slightly damp.

    When you come across rotted wood in your old house projects, instead of replacing the damaged wood, you also can repair it with specialty epoxy penetrants (also called consolidants) and fillers to make repairs. Not only is this faster, but the fixed wood is stronger than the original.

    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.

    If it's soft to the touch (wet rot) and you can remove wet wood gunk with a simple pass of your hand, then it's not likely to be salvageable. If your wood has rotted over about 20% then you have a tough choice to make.
