Wet Rot and Dry Rot

For any fungal growth to occur, there has to be Oxygen which is in the air, Food which is the wood in this case and Water, which comes into home in 1 of 4 ways,

  1. Rising damp,
  2. Penetrating damp,
  3. Faults; missing roof tiles, leaking pipes etc.. or
  4. Condensation.

Damp and wood do not mix

We cant remove the air and replacing the timbers is a last and expensive option, so we need to remove the water to permanently remove the problem which is why damp specialists are used to cure wet rots, dry rots and moulds.

The dry rot, wet rot or mould can be removed and the infected area can be treated using our specialist methods. But the water source must be detected and removed first.

Dry rots can be the hardest to treat as they penetrate through walls and deep into materials. The source of the infestation must be found. A surface spray of the visibly infected areas alone will not remove the infestation. Specialist treatments must be used by a professional contractor.

A level 1 treatment would be to prevent wet rot forming

  • promote air flow to reduce the moisture content of timbers
  • repair any leaks or penetrating damp
  • damp course any damp bricks that are in contact with timbers
  • use a combined woodworm and rot surface spray

A level 1 treatment may cost £200 to £400

This will not cover a level 2 or 3 contamination.

A level 2 treatment would be to treat wet rot

  • all of the level 1 treatments plus
  • remove infected timbers and replace with treated wood
  • use a penetrating wood paste to 1 meter beyond an infection
  • use damp proof materials between the wood and bricks
  • manage to ongoing situation with regular surveys

A level 2 treatment way cost around £1,000 ~£1,500
including carpentry

This will not cover a level 3 contamination.

A level 3 treatment would be used for a dry rot infestation

  • all of the level 2 treatments plus
  • replace all of the floor timbers in an infected room
  • insert joist hangers to break the contact with wet bricks
  • use a dry rot pellet treatment in all timbers
  • use resin replacement partially decayed large timbers
  • use a rot irrigation in the infected rooms walls and floors

A level 3 treatment is likely to cost £3,000 plus

and would qualify for an insurance backed 30-year guarantee.

Dry rot can spread very quickly, so if the treatment is started sooner rather than later, the price is likely to be lower.

As approved contractors we can offer the highest standards of treatment and provide you the peace of mind of a 30 year insurance backed guarantee.

Wet Rot and Dry Rot and Mould Surveys

this is what the surveyor will be looking for:

For any fungal growth to occur, there has to be four items present;

  1. Air ~ which can carry spores and moisture
  2. Water ~ dry timber cannot rot
  3. Food ~ which will be the timbers
  4. Temperature ~ which needs to be comfortable

There are four main causes of damp in your home:

  1. Rising damp ; from the ground up, soaked up by the bricks, the wood and the plaster
  2. Penetrating damp ; rain penetrating through the walls and breaching the cavity
  3. Faults; missing roof tiles, faulty guttering, leaking pipes, gaps in the brickwork etc..
  4. Condensation ; poor air circulation, blocked vents, gas fires, cooking etc...

Observations: Wood should never be wet in your home

  1. Food ~ Wood breaks down to release sugars which feeds the wet and dry rots
  2. Temperature ~ must be comfortable for wet and dry rot
  3. Is the moisture content in the wood sufficient to support life for wet and dry rots
  4. Have the moisture levels in the wood been raised by blocked air bricks
  5. Are there sufficient airbricks for each room, we recommend 2 per room.
  6. Has the drive or path been raised to block the air bricks
  7. White branches or strands of fungal growth indicate dry rot spreading
  8. Sheets of white growth behind skirting or sheet timbers indicate dry rot spreading
  9. Cubioding (as shown) of wood indicates dry rot
  10. Dry rot can spread across dry timbers, concrete or bricks in search of food
  11. A cotton wool like growth can also indicate a dry rot spread
  12. Dry rot has been known to spread across treated timbers in search of food
  13. Wood which goes darker, possible cubioding with a loss of strength indicates brown rots
  14. Wood which is bleached, coarse and fibrous with a loss of strength indicates white rots
  15. The fungus consumes enzymes which it converts into sugars
  16. A musty smell may be noticeable with dry rot
  17. Any softening, cracking, shrinkage or distortion of the wood can indicate a fungus
  18. Cracking which can be deep may occur with wood that has shrunk
  19. Humid stagnant conditions are most likely to cause fungal growths
  20. Optimum conditions would be 22 C+ with a 30% humidity, e.g. centrally heated homes
  21. Growths like dry rot can spread over 4 meters per year
  22. Dry rot can grow through walls and spread across a room in search of food within a year
  23. Fungus can give of microscopic spores, 0.01 mm in size which spread wildly
  24. Types of fungus include a white cotton wool appearance
  25. Dry rot growths are like a mushroom with a silvery grey skin with a yellow lilac tinge
  26. Strands of fungus supply nutrients like roots burrowed into the wet wood or bricks
  27. Strands of fungus which burrow into the wood or brickwork, cause the damage
  28. Specialist treatments must be administered straight away, especially for dry rot
  29. Severe cases require removing damaged wood 1 meter past the visibly infected timbers
  30. Ventilation should be improved by the use of vents, fans and de-humidifiers if necessary

See the table below for a detailed look at the main types of rots that can damage your timbers.
