Although dry rot develops gradually and is not always evident, the damage it causes can quickly spiral out of control.
If left untreated, this common timber fungus can compromise your property’s structural integrity and may even present risks to your health and safety.
But is dry rot dangerous enough to warrant urgent action? In short, yes. Allerton Damp Proofing strongly suggests having dry rot treated as soon as you spot any signs, to avoid health risks and costly repairs.
In this article, we will explore what dry rot is, how it develops, the risks it poses, and how Allerton Damp Proofing can help you deal with the problem effectively and efficiently.

Dry rot is a type of fungal decay that targets timber, breaking down the fibres that give wood its strength and stability.
Despite the name, dry rot requires moisture to develop. It often takes hold in hidden, poorly ventilated spaces where timber has been exposed to dampness, such as behind skirting boards, under floorboards, or in roof voids.
The fungus, Serpula lacrymans, thrives in environments with moisture levels above 20%, and can be triggered by issues like leaking pipes, rising damp, or condensation. Once established, it spreads quickly, feeding off the cellulose in timber and weakening its core structure.
While the fungus does not directly poison the air like black mould can, it can still contribute to poor indoor air quality, especially in enclosed or unventilated spaces.
The earthy smelling molecules that dry rot gives off can irritate people with asthma or respiratory sensitivities.
More significantly, the presence of dry rot often means that the property has a persistent damp problem. This damp environment can become a breeding ground for other harmful fungi and bacteria, which can even be deadly if breathed in for long periods of time.
Prolonged exposure to these damp conditions can aggravate allergies and cause respiratory distress, especially in vulnerable individuals such as children, the elderly, or those with pre-existing health conditions.
While the health risks are important to consider, another danger of dry rot lies in what it does to your property, and the safety risks structural damage can present.
Left untreated, dry rot can severely weaken floorboards, roof beams, door frames, and joists. The timber becomes brittle and crumbly, often collapsing under weight or pressure.
Because dry rot can travel through masonry and across different building materials, it is not confined to one small area. It can spread from a single leak in your loft to the lower floors of your home in a matter of months. In advanced cases, entire sections of walls and flooring may need to be removed and replaced.
This makes dry rot one of the most expensive and invasive types of property damage if it is not tackled early on.
Even before visible damage occurs, there are warning signs to watch out for.
Spotting these signs early is key to reducing the impact on your home, and your wallet.
To help you identify the early indicators of dry rot, we have put together a specialist guide on how to spot the Signs of Dry Rot.
At Allerton Damp Proofing, we specialise in identifying and treating dry rot before it becomes a full-scale structural threat.
Our experienced team carries out comprehensive inspections to locate the source of moisture and the full extent of fungal growth.
We then remove all affected materials, apply specialist fungicidal treatments, and advise on repairs or replacements. Crucially, we also fix the underlying moisture problem to prevent the fungus from returning.
