Damp and Timber Specialists for 50 years

Wet Rot Surveys & Treatment Services You Can Trust

Wet rot is a severe form of timber decay that can compromise the structural safety of a property if left untreated. Caused by prolonged exposure to moisture, it often affects floor joists, skirting boards, and roof timbers. This weakens the wood, allowing damage to spread over time.

Prokil conducts wet rot surveys and wet rot treatments for homeowners, landlords, and property professionals. Each survey is conducted by a qualified specialist, not a commission-based salesperson. You will also receive a detailed written report with no obligation to proceed.

With over 50 years of experience and 37,000 surveys undertaken across the UK, our experts provide trusted, evidence-based solutions. Our team will help restore your property and prevent further decay.

Why Choose Prokil?


We Diagnose, Treat, & Prevent Wet Rot at Its Source

Every wet rot issue begins with a source of moisture. For wet rot fungus and spores to form, a moisture content of at least 30% is generally required.

In residential properties, the most common contributors include:

  • Leaking pipes, appliances or water tanks
  • Blocked or defective rainwater goods
  • Poor external pointing or rendering
  • Raised ground levels in contact with timber
  • Inadequate ventilation in floor voids or roof spaces

Solid wall buildings are more susceptible to damage because they lack a cavity. This means moisture can move directly to the internal timbers. Our surveyors are trained to identify these issues at the source and provide lasting remedial solutions.

Our process begins with a site survey carried out by a qualified damp and timber specialist. Our team will evaluate the timber’s condition using tools such as moisture meters and borescopes. These help us pinpoint the cause of the decay and record the extent of the damage. Once complete, we will issue a written report outlining any findings, recommendations and next steps. All quotations are clear, detailed and free from obligation.

When treatment is needed, our workers will remove or repair the damaged timber. They will then apply fungicidal preservatives and set up steps to prevent it from happening again. All works are carried out to PCA standards and, where eligible, are covered by the Prokil Guarantee for long-term peace of mind.

Get A Treated Property Backed by Long-Term Assurance

Our specialists offer wet rot inspections and treatments. We tackle the problem at its source and help prevent it from happening again. The Prokil method includes proper diagnosis, effective intervention, and easy aftercare. This ensures your property remains secure in the long term.

This service is for homeowners, landlords, and property professionals. It offers accurate, report-based assessments and proven solutions that meet British Standards. Our service provides technical certainty and peace of mind. This holds true whether you’re tackling issues from a homebuyer’s survey or managing a structural concern in a tenanted building.

Unlike general contractors, we offer reports, photographic records, and transparency at every stage. You will receive a detailed breakdown of suggested works that covers timelines and estimated costs. Best of all, there is no pressure from our end to move forward. We can collaborate with your surveyor, mortgage lender, or insurance provider as needed to ensure everything aligns correctly.

How to Recognise Wet Rot in Your Property

  • A musty or mushroom-like odour near timber structures
  • Discolouration, shrinking or cracking of skirting boards
  • Springy or uneven floorboards, when walked upon
  • Timber that feels soft, spongy, or crumbles when touched
  • Visible fungal growth, strands, or a fibrous texture on wood

These signs can indicate an active decay process that requires professional investigation. A Prokil survey will confirm whether wet rot is present and determine the extent of any structural impact.

The guys who carried out the work did a great job, and they were incredibly helpful, quiet and polite. Despite having to do a very messy job, they left things immaculately clean a tidy, and it was a pleasure to have working in my home.

If left untreated, wet rot can compromise the structural integrity of floors, stairwells, or roof areas. We prioritise stabilising, repairing, and protecting affected areas before they worsen. Once the remedial work is complete, your property will be left dry, safe and ready for future occupancy or sale.
