Dry rot treatment in Halifax, West yorkshire is easily available from specialists and can be an important way out for home owners struggling with dry rot fungus. Dry rot fungus destroys wooden structures in many parts of the world and is not limited to Halifax, West yorkshire.
Known for its ability to destroy timber in buildings, the first step in its control is usually to identify that an infestation exists.
Some other wood destroying fungus such as wet rot can also be involved in damaging wood and so a clear distinction should be made. One distinguishing factor is that dry rot can invade building materials other that timber and result in outbreaks that have the potential to spread through a building quickly.
Dry Rot identification and treatments in Halifax
To overcome dry rot fungus requires extra measures compared to the conventional treatments for other wood rotting fungi. Such measures include masonry sterilization. Some indications that dry rot infestation is occurring in a structure include shrinking wood that darkens and cracks in a cuboidal manner, silky grey, mushroom colored layered cover over wood that has a color of yellow and that develops in low humid condition.
This layer is usually easy to peal just like mushroom. The development of white fluffy ‘cotton wool’ like organisms that develop in humid conditions with the shape of tear drops also developing on the wood.
Dry rot fungus also develop strands on the surface where they are invading which crack when they dry. Dry rot is more invasive that wet rot because even after the removal of damp conditions, it will continue to grow. After starting with timber dry rot continues to the brick work and mortar.
Dry rot usually affects damp wood with moisture content of 20%. Hence the first step in dry rot treatment is the eradication of moisture. Some of the reasons wood becomes wet include leaking pipes, and water invasion.
There are a number of treatments for dry rot including; orthodox methods which lay an emphasis on the use of chemical fungicides, environmental control where adjustments in environmental conditions are used to eradicate dry rot fungus, heat treatment which is a dry rot fungus treatment and biological treatment which employs the use of competitor organisms to eliminate the dry rot fungus.
Methods of dealing with a Dry Rot outbreak
Orthodox methods are typical of traditional methods of treating dry rot fungus. All wood containing the decay is cut out from the infested structure. This includes all sound timber that is within one meter radius from the nearest visibly decayed timber. These wood is burnt.
The next thing is to hack of all the adjacent plaster and renderings. All skirting, linings, paneling and ceilings are also stripped off so that all traces of the dry rot fungi to the area removed before they spread further to adjacent concrete or masonry.
Next, a wire brush is used to clean all the surfaces and any steel piping or steel works that are adjacent for up to 1.5 meters after the furthest extent of the suspected infection.
After removing dust from the building using the wire brush, the next thing is to apply fungicide to the structure, concrete and earth surfaces. Two generous coats of fungicide are usually applied on all the timber surfaces. When replacing the woodworks, timber treated with preservatives is usually used.
Finally the building is plastered using zinc oxychloride or repainted with zinc oxychloride paint. When applying fungicides, some buildings are sprayed with water soluble fungicide in a process referred to as wall irrigation. For walls that are thick, holes drilled at least 230mm apart are used to inject the fungicide into the wall. For walls that are close to 500mm, drilling should be done on both sides.
When using environmental treatment, the sensitivity of dry rot fungi can be exploited to treat infested walls. The first step in this dry rot treatment approach is to ensure the affected surface area. This can be done by using forced ventilation from fans. Home owners should avoid re-plastering and redecorating the home to because this can cover the affected woodwork and walls and prevent complete drying.
The next thing is involving a structural engineer to analyze the weaknesses of the structure and point out the parts that should be replaced and where loss of structural strength carry. The ventilation in the house should be increased to ensure the rapid drying of the building. In addition, any wood that takes long time to dry out should be isolated.
