"I've used Tapco twice now for damp-proofing a wall and also damp proofing an entire basement storage space using a membrane system. They are very reliable and punctual, and the work has been to a high standard (so far no damp!). This sort of work needs to be done properly..."

The timbers of a building can face one of a number of problems and here we look at how to deal with some of the most common, including dry or wet rot and woodworm infestations.
In-situ treatment of built-in beam ends
For some years now, the HSE Guidance Notes on dealing with such conditions has recommended using ‘in-situ timber treatment using timber preservatives’ –
‘a special form of emulsion which is applied as a thick paste to the surface of the timber where deep penetration is required, and/or where it is necessary to keep a concentration of a pesticide product in a precise place. They are normally applied by trowel, caulking gun or brush and are both insecticidal and fungicidal in action’
At Tapco HomeDry, this means we use fungicidal or insecticidal products that are applied to timbers in the form of a gel or a paste. The gel has a concentration of fungicide in am emulsion that means it can deeply penetrate the timbers to kill any fungal spores or growths that it encounters.
Should the timber be wet at the time of application, the active ingredients diffuse rapidly into the timber. This prevents both fungal decay and also wood boring beetles until the timber has dried down to a moisture content that doesn’t support fungal growth.
On the other hand, if the timbers are dry when the product is applied, it will diffuse and provide protection should the wood become wet at any time in the future as this is when it is vulnerable to fungal attack.
When controlling fungal decay, it is also important to take steps to eliminate sources of moisture that have led to the condition. Therefore, we will often undertake preventative steps alongside chemical treatments to complete and overall repair.
What does it mean when wood turns black?
Black wood in a property can mean one of a number of things and an expert will be able to diagnose which is the case in your property. Reasons include:
Wood rotting fungi attacking including dry rot and cellar fungus – these can also turn the wood brown
Prolonged exposure to moisture
Black spot mould on the surface of the wood due to high condensation levels
Oak is one wood that is particularly prone to turning black under several conditions.
