Wet Rot Detection, Treatment & Timber Restoration
At Armon, we tackle wet rot by first identifying and resolving the source of moisture causing the problem. Our team then removes all damaged timber, treats the surrounding wood with specialist preservative products, and replaces any structurally compromised sections where needed. The result is a fully restored, protected, and structurally sound property — backed by our 25-year guarantee.
Key Warning Signs That Your Property May Have Wet Rot
- Timber that feels soft, spongy, or gives way easily under light pressure
- Visibly darkened or discoloured wood compared to surrounding healthy timber
- Paint or surface finishes cracking, peeling, or lifting away from affected timber
- Timber that appears warped, shrunken, or distorted in shape
- A persistent damp or musty smell emanating from floors, walls, or ceiling timbers
- Fine cracks running along the grain of the timber surface
- Visible fungal growth appearing as white or dark coloured strands on affected wood
- Structural weakness or movement noticed in floors, joists, or window frames
If any of these signs are present in your property, contact Armon without delay for a professional wet rot assessment before the damage progresses any further.
The Most Common Causes of Wet Rot in Residential Properties
- Persistent water leaks from plumbing, pipework, or appliances making prolonged contact with nearby timber
- Damaged, blocked, or overflowing gutters and downpipes allowing water to saturate external timber frames and fascias
- Defective or poorly maintained roofing permitting rainwater to penetrate and repeatedly soak roof timbers
- Failed window or door seals allowing moisture to accumulate within surrounding timber frames over time
- Rising damp travelling upward through ground floor timbers, joists, and floorboards
- Inadequate subfloor ventilation causing humidity and condensation to build up beneath suspended timber floors
- Poor external drainage resulting in groundwater pooling against and saturating the base of external walls
- Leaking or cracked render trapping moisture directly against external timber elements
Unlike dry rot, wet rot requires a continuous source of moisture to survive. Armon’s specialist surveyors identify and eliminate the root cause of the moisture problem first, ensuring wet rot treatment delivers a permanent and lasting result.
At Armon, we take a straightforward and effective approach to fully eliminating wet rot and protecting your property against any future recurrence:
- Inspection & Assessment — A detailed survey to identify all areas of wet rot and accurately determine the full extent of timber deterioration throughout the property
- Moisture Source Resolution — Locating and permanently fixing the underlying source of water or dampness feeding the wet rot before any treatment begins
- Damaged Timber Removal — Careful removal of all structurally weakened and decayed timber to prevent the spread of further deterioration
- Preservative Treatment — Application of specialist timber preservative products to all surrounding and adjacent woodwork, creating a protective barrier against future fungal activity
- Timber Reinstatement — Replacement of removed structural elements using pre-treated compatible timber, fully restoring the integrity and strength of the affected areas
- Final Inspection — A thorough post-treatment check to confirm all wet rot has been fully eliminated and the property is structurally sound and protected
Every wet rot treatment completed by Armon is backed by our 25-year guarantee — ensuring your timber stays strong, stable, and fully protected for years to come.
Our Dry Rot Treatment Process
At Armon, we follow a clear and effective process to eliminate Dry rot and protect your property for the long term.
How does Armon determine whether my property has wet rot?
Armon’s qualified surveyors carry out a thorough on-site inspection using advanced moisture meters and hands-on structural assessment to accurately identify all areas of wet rot activity. We assess every affected timber element in detail — including floors, joists, window frames, and roof timbers — ensuring nothing is missed before treatment begins.
Does Armon fix the source of moisture as part of the treatment?
Absolutely. Wet rot cannot be permanently resolved without first eliminating the moisture source sustaining it. Armon always identifies and addresses the underlying cause of dampness — whether that be a leaking pipe, failed guttering, defective roofing, or poor drainage — before carrying out any timber treatment, ensuring the problem does not return once works are complete.
Will all of the damaged timber need to be removed and replaced?
Not necessarily. Where timber remains partially sound and structurally viable, Armon can apply specialist consolidant and preservative treatments to stabilise and protect the affected wood without full replacement. However, where timber has deteriorated beyond recovery, our team will carefully remove and replace it using pre-treated compatible materials, fully restoring structural integrity.
How long does wet rot treatment typically take to complete?
The duration of treatment depends entirely on the scale and severity of the wet rot identified during the initial survey. Smaller, localised cases can often be resolved within a single day, whilst more extensive infestations affecting multiple structural elements may require two to three days or more. Armon will always provide a clear and accurate timeframe following the initial assessment so you know exactly what to expect.
