Dry Rot explained

What is dry rot?

Dry rot (Serpula lacrymans) is the most destructive timber decay because it can spread through masonry as well as wood, even into relatively dry areas, in search of more timber to consume. It shows as red-brown spore dust, white or grey strands and mushroom-like fruiting bodies. Eradication means removing affected timber, treating the surrounding structure, and — most importantly — eliminating the damp that allowed it to grow.

Know the signs

Signs of dry rot to look for

Spotting it early keeps the repair small. These are the tell-tale signs in North East homes:

  • Reddish-brown spore dust on or near timber
  • White, cotton-wool-like or grey spreading strands
  • Mushroom-like fruiting bodies (orange/brown discs)
  • Timber that's dry, brittle and cracks into cubes
  • A strong, damp, mushroomy smell
Common causes

Why dry rot happens

  • Persistent damp from leaks, rising or penetrating damp
  • Unventilated, enclosed timber such as floors and cellars
  • Water ingress through roofs, walls or plumbing
  • Long-standing moisture in older North East properties
  • Concealed damp behind panelling or plaster
Our proven process

How we treat dry rot

Diagnosis first, then a lasting, guaranteed fix — never a sticking plaster.

Survey & determine spread

We establish the extent of the outbreak, including any spread through masonry, and find the moisture source.

Remove affected timber

Decayed timber is cut out well beyond the visible decay and disposed of safely.

Treat the structure

Surrounding masonry and timber are treated to kill the fungus and prevent regrowth.

Fix the damp & rebuild

We remove the moisture source, reinstate sound timber and guarantee the qualifying work.

Dry Rot FAQs

Why is dry rot more serious than wet rot?
Because dry rot can travel through brickwork and plaster to reach new timber, an outbreak can spread surprisingly far from the original damp area. That's why it needs prompt, thorough treatment rather than a patch repair.
Can dry rot be completely eradicated?
Yes. Removing decayed timber, treating the surrounding structure and — critically — eliminating the damp source stops dry rot for good. It cannot survive in dry conditions, so moisture control is the key to permanent eradication.
How much timber needs removing?
Affected timber is cut back beyond the visible decay to be safe, but we don't strip out more than necessary. The survey defines the extent so you know exactly what's involved.
Is dry rot treatment guaranteed?
Yes — qualifying dry rot eradication is backed by a written guarantee.
