Timber treatment:  woodworm, wet rot and dry rot

Woodworm is actually a generic term for a number of wood boring insects that can infest your home and attack the wood, the most common of these being common furniture beetle (Anobium Punctatum). Woodworm is often associated with dampness as poor ventilation and high humidity are aspects of both problems. You may have woodworm if you can spot exit holes in your wood which can be up to 2mm in diameter along with small piles of bore dust. If you are unsure then Damptec are available to conduct a survey and recommend the correct course of action if woodworm is present.


We operate in accordance with the Property Care Association (PCA) Remedial Timber Treatment Code of Practice based on current best practice for the in situ treatment of common wood destroying beetles and fungal decay for contractors specialising in remedial treatment. Damptec staff have received training in the safe and effective use of the products involved.


Our Treatment Method

For a room infested with common furniture beetle, for example, we would recommend a blanket treatment using a microemulsion wood preservative concentrate formulated for the in-situ treatment of timbers which are affected by wood boring insects.


The preservative concentrate we use for common furniture beetle has the following properties:

  • One hour re-entry of the treatment area:

  • Excellent penetration into timber

  • Non-flammable with a very low odour

  • Effective against all wood boring beetles

  • Non-hazardous


Warning notices are displayed after treatment has been carried out stating the re-entry time.


Replacement timbers must be pre-treated in accordance with BS8417 2003 or treated on site with wood preservative meeting the requirements of BS 8417 2003. 

Case Study

In the case study below we were contacted by Mary in Stoney Middleton, Derbyshire when she discovered a common furniture beetle infestation in the bathroom of a house which she owns. The pictures below detail the treatment process carried out by Damptec.

1. Vacuuming of the treatment site to remove debris and dust to allow full access to the timbers and limit dust borne contamination.
2. Once the site has been cleaned it is ready for treatment. The preparation stage is important in ensuring the success of the treatment.
3. The site is sprayed with a micro-emulsion wood preservative concentrate and a warning card left at the entrance to the property stating the re-entry time which, in this case, was 1 hour. This work was completed in one day.

The owner, Mary, said of our work:

“Carl from Damptec Systems Ltd did an excellent job for us when we were in a very difficult position. We were in the process of renovating a property that a tenant had left in very poor condition. On removing the bath we discovered to our horror a mass of wood worm that had spread from the floor in to the joists and a partition wall ! This was a disaster as the bathroom fitters were already booked to give us a brand new shower room.


Once we had spoken to Pam the panic subsided and things just got better and better. Carl was brilliant, friendly, reassuring and totally professional, he kept us informed along each step of the treatment process. The work was completed in a day and Carl left the property clean and tidy. We have a lovely shower room now, thanks to Damptec! We would not hesitate to recommend Damptec. They are brilliant".


Wet rot and dry rot

Wet rot and dry rot are a serious cause of damage to the wood in your home with dry rot requiring extensive treatment compared to other forms of wood rot. Dampness is a prerequisite for an attack of rot which is essentially a fungal decay that can affect the timber in your home. It will attack the wood leaving it dry and brittle or dark and crumbly.


The experts at Damptec will deal with the damp issues associated with the spread of wet and dry rot in your home. Our experts are highly trained as the correct diagnosis is vital because the treatment will differ depending on the type of fungus. Dry rot, for example, will require extensive treatment as it can spread through masonry unlike other forms or rot which are generally restricted to the initial damp area.


Please note that Damptec Systems Ltd will treat timbers in situ but will not be involved with replacing the affected timbers or installing new timbers.
