    The "Cancer" of Buildings in Suffolk, Norfolk & Essex

    Dry Rot (Serpula lacrymans) is the most destructive wood-destroying fungus found in the UK. Unlike other rots, it has the unique ability to travel through inert materials like brick, stone, and mortar to find new timber to attack.

    It can spread from a damp cellar right up to the roof timbers, digesting the structural wood as it goes. If left untreated, it can cause floors and roofs to collapse.

    Urgent Action Required

    If you suspect Dry Rot, you must act immediately. It can grow up to 80mm per day in optimal conditions. Do not disturb the outbreak as this can spread spores. Call us now.

    How to Identify It in Suffolk, Norfolk & Essex

    1. Mycelium

    Silky white sheets or cotton-wool like cushions appearing on wood or brickwork. Can have yellow/lilac tinges.

    2. Fruiting Body

    A large, soft, fleshy mushroom-like growth (sporophore). Usually rusty red in the centre with white margins.

    3. Dust

    Millions of fine rust-red spores (dust) covering surfaces around the outbreak.

    4. Cracking

    Wood dries out, shrinks, and cracks into large cubes (cuboidal cracking). It becomes light and brittle.

    Our Elimination Protocol in Suffolk, Norfolk & Essex

    1. Locate & Identify

    We trace the full extent of the outbreak. This often involves removing plaster, skirting, and floorboards to find how far the mycelium strands have travelled.

    2. Rapid Drying

    Dry Rot needs moisture to survive. We identify the water source (leaks, condensation, damp) and fix it immediately to begin the drying process.

    3. Cut Out & Sterilise

    We cut out all infected timber plus 1 metre of healthy wood to ensure safety. We then drill the masonry walls and irrigate them with a powerful fungicide (masonry biocide) to kill any strands hidden in the wall.

    Act Fast in Suffolk, Norfolk & Essex

    Dry Rot spreads quickly. Professional intervention is critical.

    Recognising Possible Dry Rot

    Which timber and wall clues can indicate possible dry rot?

    Possible signs include timber that has become brittle or cracked into block-like pieces, fungal growth, or strands spreading across nearby surfaces. These clues are not enough to identify a fungus or confirm its extent; other decay can cause similar timber damage. Avoid disturbing extensive growth and check for the moisture source as well as affected wood. A competent inspection is needed to establish the diagnosis and repair scope.
