    After preparing the area, apply an epoxy consolidant and let it dry and harden for a week. Some consolidants dry faster if you can't wait. You can apply wood filler before the consolidant has dried.

    Quick-drying wood hardener gives you 10-15 minutes to shape the material before it dries. After everything has dried, smooth the surface with sandpaper.

    Then paint or hire a licenced exterior painter. This takes time. Wood rot repair may take a day or two to complete. As everything needs to dry, the job may not be finished for a week, but that's just waiting.

    Common Causes of Rotten Wood Sidings

    Rot, mould or mildew usually affects wood sidings the most in multiple ways. Several reasons for damage to wood siding can be:

    • Holes poked by woodpeckers to find insects underneath
    • Pests such as rodents or termites residing in the sidings
    • Missing ring-shank nails caused by age or movement
    • Moisture penetrating through missing or cracked caulking
    • Common wear and tear due to weather
    • Impacted by extreme weather conditions such as blown debris or tree limbs etc.

    Maintenance Neglecting wood siding maintenance can also let water into the felt paper underlayment. Interior and exterior signs of water damage are visible. Loose or cracked clapboards can lead to rot damage.

    If you're painting your house every other season due to fading or blistering, find the cause. Fading, blistering, and peeling paint are also signs of water damage. Wood rot is indicated by exterior fungus and interior mould. If you see these signs of wood siding rot, call a pro. Safety first!

    How to Make Your Repairs Last Long

    Once you have repaired your wood siding rot, it is better to look after it to make it last longer. Here are some tips on how to maintain wood sidings:

    • The back and edges of the new sidings should be primed and thoroughly painted.
    • Avoid driving nails flush or countersink them. The heads might break the paper face, and water will soak in and damage the siding. Seal any nailheads that break the paper face with cement.
    • Leave a gap of ⅛ inches at corners and butt joints and seal them with 35-year, paintable acrylic caulk.
    • Install gutters to prevent water from splashing on the sidings. Also, install lawn sprinklers in a way that the water does not hit the sidings.
    • Leave a 1-inch gap between siding and shingles so that the siding does not rot when it touches the roof.
    • Use fibre-cement siding to replace rotted areas. It is ⅛ inches thinner and is highly rot-resistant and also has a comparable cost. It also carries a 50-year warranty.

    When to Call for Help?

    Damage size determines whether to call for help. Pest or termite holes must be filled with wood putty immediately. Homeowners can replace one or two clapboards themselves. Surface dry rot can be deceiving.

    Call local termite control experts if the infestation is severe. Once you notice damaged wood siding, call a pro to assess the damage. You may think you only need to replace the clapboard, but the underlayer may be damaged. For a thorough inspection, hire a professional.

    Why is it not a Good Idea to do it Yourself?

    The process of replacing wood siding does not present any significant challenges. Nevertheless, it does involve a variety of steps, such as removing the rotten siding by cutting it off, removing the old nails, cutting the new siding to the required length, and caulking it to make it watertight.

    If you mess up any one of these steps, you run the risk of causing damage to the clapboards that are already there, which will drive up the cost of repairs even further. As a result of the lengthy process, homeowners may experience increased levels of frustration. Contractors not only have the necessary tools and expertise to finish the job correctly, but they also know how to repair dry rot siding in a way that is long-lasting.

    Why Replacing Rotted Wood Is Important Before You Paint Your House

    Before you make any changes or improvements to your home, such as painting the walls, installing new windows, or working with a roofing contractor, it is essential to conduct a thorough inspection of your property. Before you make any significant adjustments, it is important to determine whether or not the house requires any repairs. If you are able to identify potential problems in a timely manner, you will have the opportunity to address those concerns and may be able to avoid incurring significantly higher costs in the future.

    If you find rotting wood on the exterior of your home, this is going to be one of the most important areas that needs to be repaired. Before moving on to the next step, it is necessary to replace any wood that has started to rot. Sadly, a significant number of people are under the impression that covering rotten wood with a fresh coat of paint will prevent further deterioration. The application of a few coats of paint may give the appearance that it has halted the progression of the wood's deterioration, but in reality, all it does is hide what is going on beneath the surface.

    Why Rotted Wood Needs To Be Replaced

    In particular, if you are in the process of selling your home, rotting wood that needs to be repaired is something that should be addressed immediately. When it comes to the maintenance of your home, however, rotting wood is an indication that there may be a more significant problem.


    When wood begins to rot, this indicates that its integrity has been compromised in some way. In most cases, moisture combined with other components such as mould or mildew has already made its way through the surface and into the interior of the structure. Painting over the damage after it has occurred has no effect on the deterioration because it has already spread into the wood itself, thereby compromising the wood's strength and integrity.

    Signs of Other Issues 

    Even though there are some instances of rotting wood that are not related to the rest of the house in any way, the majority of the time it is an indication that something else may be wrong. It is possible that all of the wood on the surface is beginning to rot, or it is possible that the integrity of the home itself has been compromised by moisture, mould, pests, or some other type of invader. You are not solving the problem by painting over it; all you are doing is concealing the real reason why the wood is rotting.


    Termites are another culprit that could be responsible for the rot in the wood, particularly if the damage is taking place in the lower levels of your home. Termites attack wooden structures in search of food and will do so even if the wood has been painted over. It is necessary to get rid of the wood because it might be home to termites, which could then spread to other parts of your house.


    Rotted wood is not only disintegrating, but it has also lost a significant amount of the natural strength it possessed as well as its resistance to the external elements. It is much simpler for the elements to penetrate the wood and compromise your home, even if the exterior paint is brand new. Ruptured wood that has been painted can be damaged and compromised by high winds, hail, sleet, and even rain.

    FAQs About Wood Rot

    Boric acid (borate) is one of the most effective fungicides for use in treating wood rot. It can be applied to wood during construction to prevent future rot, or as a treatment to stop an active decay fungus from growing.

    What is Wood Rot? It is decay caused by fungal growth in damp wood. When timber becomes damp enough to have 20% or more moisture content, and isn't able to dry out quickly or is repeatedly dampened, it creates the ideal conditions for wood-eating fungi.

    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.

    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.

    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.
