Wet rot is a type of fungal decay that requires timber to have a high moisture content, causing the structure of timber to become saturated.

The fungi will then consume the timber by feeding on the nutrients, which over time can cause a loss of structural integrity.

Wet rot differs from dry rot in that it requires a higher moisture content to grow and is typically isolated at the source of moisture.

Wet rot will often occur in hard to reach areas, and can be found in timber which is in contact with damp masonry.

In order to prevent wet rot from returning you must address the source of moisture, whether this is from building defects such as leaking gutters or blocked drains, from penetrating damp, rising damp or condensation. Because of this, elements of damp proofing or improvements to ventilation may be required.

Once the source of moisture has been dealt with and the timber starts to dry out, you will stop the wet rot problem. Timber that has lost its structural integrity will need to be replaced.

If you are worried about a wet rot problem affecting your property, a damp and timber survey is the first step in fully understanding the issue, and providing you with long term solutions.

A CSTDB or CSRT qualified surveyor is skilled in identifying the different types of fungal decay and the associated damp problems in buildings, and will provide you with a detailed survey report outlining their findings.

A professional surveyor will inspect the extent of the damage, and confirm whether or not the problem is wet rot or dry rot. To an untrained eye they may appear similar, but because the treatment process is different, accurate identification is key.

They will also check both the exterior and interior of the premises, to identify the source of damp causing the outbreak. A thorough inspection is required, as often fungal decay can remain hidden under floorboards, behind panelling or in out of sight areas. 

If these areas are not thoroughly inspected, or a source of moisture is missed, the wet rot problem can return.

Once a qualified surveyor has inspected the property in order to fully understand the source of moisture, the extent of the fungal decay and the condition of affected timber, they will provide you with a survey report outlining their recommendations for treatments.

This will be provided to you in an easy to read format within 72 hours, so you know exactly the requirements for treatments.

The cost of treating wet rot will vary depending on numerous factors, including the extent of damage to timber, if damp proofing is required or if elements of plasterwork need to be replaced.

Since every case is unique, it's challenging to provide an accurate estimate without first understanding the size, scale, and extent of the problem.

In some situations, the wet rot may be limited to decorative timbers, while in others, it may have spread to structural elements or be accompanied by related issues such as woodworm or dry rot. These variables all impact the overall cost of repair.

The most reliable way to understand the potential costs for remediation is to arrange for a professional survey. Our specialists will inspect your property, identify the source of moisture, assess the level of damage, and provide a detailed report with an itemised breakdown of the costs involved.

  Can I Treat Wet Rot Myself?

  Minor wet rot issues in decorative timber, such as window ledges or skirting boards, may be possible to treat yourself with certain products.

  These typically include fungicidal treatments and wood hardeners designed to halt fungal activity and reinforce weakened areas. If the decay is minor and localised, and the source of moisture is obvious (like a leaking appliance), some homeowners attempt DIY wet rot treatment.

  However, once wet rot affects structural timber, or if the source of damp is hidden or persistent, repairs are much more complex.

  Replacing timbers or treating inaccessible areas without the right tools and knowledge can exacerbate the problem or simply just delay its return.

  The most significant risk with DIY attempts is failing to address the underlying moisture issue. If the damp conditions aren’t fixed, the fungus will return.

  That’s why it’s always best to consult a qualified wet rot specialist, especially if it's affecting areas like floor joists, beams, and basements or you're unsure where the rot is coming from.

  DIY repairs rarely work long-term. Only a qualified wet rot specialist can provide guaranteed, lasting results.

  Will wet rot spread once dry?

  No, once the source of moisture has been removed, the wet rot problem will stop progressing. Wet rot requires timber to have a high moisture content in order to grow and decay timber. Unlike dry rot, wet rot will not spread through masonry in order to find new timber to attack. Stopping the moisture issue is an essential first step in solving the problem, but you must also address any timber that has lost its structural integrity.

  What kills wet wood rot?

  In order to eradicate and remove a wood rot problem, you must remove the source of moisture that has increased the moisture content of affected wood. Once you remove the source of moisture the wood will start to dry and the fungus will stop growing. Fungicidal treatments can also be used in order to prevent the rot from spreading. Where structural timber has been affected by wood rot, it's important to seek advice from a professional.

  Is Wet Rot Treatment Covered by House Insurance?

  Standard home insurance will not typically cover wet rot treatments or the repair of rotted timbers. This is because many insurers see wet rot as a maintenance problem which is the homeowners responsibility to prevent from occurring.

  If another issue has caused the wet rot problem such as a burst pipe, you may be able to check your policy to see if you are covered.

  Can you fix wet rot in listed buildings?

  Yes, many listed and heritage buildings in the United Kingdom are affected by wet rot every year, and specialist care must be taken in order to protect them long term.

  Peter Cox has vast experience working on some of Britain’s most prestigious buildings, and work closely with heritage and conservation bodies, their professional advisers and property guardians such as the National Trust.
