Quick answer

How serious is dry rot? Dry rot (Serpula lacrymans) is the most serious form of timber decay: unlike wet rot, it transports its own moisture and spreads through masonry, behind plaster and across timber far from the original damp source. It can cause major structural damage if untreated. Professional eradication — removing affected timber, treating masonry and fixing the moisture source — is strongly recommended.

Spot the warning signs

Signs of dry rot in your home

Caught early, dry rot is far cheaper to fix. If you recognise any of these, it’s worth getting a local expert to take a look — our advice is free.

  • Cuboidal cracking — timber shrinking and breaking into cube-shaped pieces
  • Cotton-wool growth — white, fluffy mycelium spreading across wood and walls
  • Rusty red spore dust — fine brick-red dust settling near affected areas
  • Mushroom-like fruiting bodies — pancake-shaped growths with red centres
  • Grey-white strands — root-like hyphae crossing masonry and plaster
  • Damp, fungal smell — a distinctive mushroomy odour in affected rooms
Why it happens

What causes dry rot?

Dry rot starts the same way as wet rot — timber soaked by a leak, rising damp or condensation — but Serpula lacrymans doesn't stay put. Once established, it produces moisture-carrying strands that cross brickwork, travel behind plaster, and infect dry timber metres from the source.

That spreading ability is why dry rot demands professional eradication. Treating only the visible growth leaves hidden strands alive in the masonry, and the outbreak returns. Our specialists map the full extent before any treatment begins.

Not sure this matches what you’re seeing? Book a local damp survey and we’ll diagnose it properly — survey fees are discounted from any work you go ahead with.

Our proven fix

How we treat dry rot

Urgent specialist survey

We confirm dry rot, trace the moisture source and map the true extent of the outbreak — including hidden spread.

Remove & contain

Affected timber is cut out beyond the visible decay; surrounding masonry and timber are treated with targeted fungicides.

Kill the conditions

The moisture source is eliminated and ventilation improved, removing the environment dry rot needs to survive.

Rebuild with protection

New pre-treated timber is installed and works carry our 30-year guarantee.

Every job protected for 30 years.

All dry rot works are completed by checked & vetted local specialists and come with a 30-year guarantee — so you can fix it once and forget about it.

Dry Rot FAQs

How quickly does dry rot spread?
Under favourable conditions dry rot mycelium can grow several metres per year, travelling through walls and floors. Outbreaks discovered early might involve one joist end; left for a couple of years, they can involve whole floors. Speed matters.
Can I treat dry rot myself?
DIY treatment is strongly discouraged — the visible growth is only part of the organism. Without mapping and treating the hidden strands in masonry, the outbreak will return. Professional eradication with a guarantee is the only reliable fix.
Does dry rot mean my house is structurally unsafe?
Not necessarily — it depends on what's been affected. Decayed joists, lintels or roof timbers do lose strength, which is why prompt professional assessment is essential. Most outbreaks we treat are resolved before structural intervention is needed.
Why is it called dry rot if it needs moisture?
Because it can decay timber that appears dry — the fungus transports moisture from its source through root-like strands. It still needs an initial damp source to germinate, which is why fixing that source is central to treatment.
Is dry rot treatment guaranteed?
Yes — dry rot eradication completed by our checked and vetted specialists carries a 30-year written guarantee.

Stop damp before it spreads — and costs you more.
