Woodworm & Fungus Treatment


We conduct all of our woodworm surveys in the only way it should be done. We search for actual evidence that there is in fact active woodworm. We ascertain current or historic activity, measure wood-moisture contents, and take relative humidity (RH) atmospheric readings of the surrounding areas. Once we’ve compiled these readings, we’ll give you a definitive answer to the issue and how you can reverse the effects.

Woodworm is an indicator of more serious and pressing issues – such as high atmospheric moisture levels or penetrating damp due to an external defect. This is what needs identifying. Woodworm activity is indicative of heightened moisture levels.

We offer a comprehensive report explaining the situation as a whole and all the environmental impacts the situation’s having on your property. So, having identified the source of the problem, we then put forward a plan of attack. This will involve the monitoring, drying and reversal of the conditions that subsequently led to Mother Nature mistaking your home for a forest floor.

Fungal decay

Both wet rot and dry rot are types of fungal decay. For us, the first important task is to identify which type of rot your building has and where the water’s coming from that’s giving the fungus life.

There are many different types of wet rot, but only one dry rot fungus. Worry not, Sussex Dampworks has the expertise to identify the exact fungus and what’s keeping it alive.

Different funguses survive on different levels of moisture content. Wet rot needs a high level to grow (50% and above), whereas dry rot germinates at a lower level (around 20%-30%). Both types feed on the timber they infest, weakening the structure and, ultimately, causing it to collapse.

Wet rot is often a result of defective plumbing, gutters, downpipes or damp abutting masonry. Fortunately, it doesn’t spread through masonry and its growth stopes when moisture’s removed.

What to look for:

  • Mycelium strands (like cotton wool) appearing on timber
  • Timber shrinkage and cracks to the timber
  • Timber that feels feel soft and spongy to touch
  • Evidence of timber discolouration

Dry Rot

Annoyingly, dry rot often occurs in areas of the property that can’t be seen – so significant damage might occur before the problem is identified.

Areas such as attics or floor voids (that have poor ventilation) can have higher-than-normal moisture content. A mushroom scent in the air (and reddish-white fruiting bodies) are a sign of dry rot.

Dry rot can travel through and along the wall surface behind plaster or render. Water is its life blood – without it, it’ll die and so long as the source is fixed and the area stays dry, it’ll never appear again.

What to look/sniff for:

  • A white mycelium growth (like cotton wool) appears when fresh (it can have a lemon-yellowish tinge, but turns grey when older)
  • The timber will usually have large cuboidal cracking and crumble when badly affected
  • A damp musty smell
  • Red spore dust from the fruiting body
  • Damaged paint finish

Please note – We charge a small fee since we are reporting on the symptoms, and not quoting for them. Hopefully, work may not even be needed. However, if work is required, all fees paid prior to our inspections are refundable upon final invoice of any subsequent work that you may need.)
