Wet and Dry Rot

Our fully qualified surveyors are able to identify the nature, type and extent of the dry or wet rot, identify the cause and source of moisture and recommend the solution with a full specification and the cost of the repair.

Dry and Wet Rot are usually caused by dampness, poor ventilation, high relative humidity and bad maintenance or a combination of these conditions.

Dry and Wet Rot can cause major structural defects in buildings, particularly to existing timbers. It is unsightly and unhealthy and can grow at an alarming rate in certain conditions.

Fruiting bodies of the fungi release millions of spores into the atmosphere. They are omnipresent (constant everywhere) waiting for suitable conditions to germinate and If sufficient moisture becomes present, the spores will germinate initiating fungal development. From this point the fungi will use the timber as its food source causing the timber to deteriorate and eventually the timber will lose its structural integrity.

Dry Rot (Serpula lacrymans)

Dry rot is the more virulent type of wood rotting fungi and specialist advice is imperative in order to identify the fungus and determine its true extent and make recommendations in relation to the extent of the repairs required and the necessary specialist treatments.

To successfully eradicate Dry Rot you must initially eliminate the source of moisture. The works will normally involve the replacement of decayed timbers, removal of wall plaster to expose extent of decay and mycelial growth and the treatment of the wall structure by masonry irrigation and returning the area to a watertight condition.

Wet Rot (eg: Coniophora puteana)

Wet rot is a term of general classification covering all the wet rot species of decay, one of the most common being Coniophora puteana.

Treating outbreaks of Wet Rot is generally less involved than those associated with Dry Rot. The works will normally involve the replacement of the decayed timbers only, however it is still vital to ensure that the moisture source is eliminated or at least isolated from the timber.

Our fully qualified surveyors are able to identify the nature, type and extent of the dry or wet rot, identify the cause and source of moisture and recommend the solution with a full specification and the cost of the repair.

Our fully trained and qualified technicians will carry out the specialist work using only the safest chemicals available for the specific treatment.

Wet and Dry Rot – frequently asked questions:

What is wet rot?

Wet rot is a form of timber decay. There are many forms of wet rot and all require the same treatment. They may cause darkening of the timber (brown rot) or bleaching (white rot).

What is dry rot?

Dry rot is the most serious form of timber decay. It is a brown rot that typically occurs on wood embedded in, or in contact with, wet masonry. It is sensitive to heat and light and therefore is rarely found on exposed external timbers. It has the ability to transport moisture from damp areas to dry timbers thus promoting the spread of the outbreak, especially in unventilated areas.

Typically the timber has deep cracks both along and across the grain. There is also a distinctive mushroom smell when dry rot is prevalent.

Can wet and dry rot be treated effectively?

Both can be successfully treated following a detailed inspection by a professionally qualified surveyor (CSRT – Certificated Surveyor in Remedial Treatment).

What chemicals do you use?

In the treatment of Dry Rot we use the latest Boron products. Boron compounds are vastly superior in terms of the control of Dry Rot and the purpose of the chemical surface irrigation is to provide a reliable protective cordon around the infected area to prevent the reoccurrence of spread of the fungus.

What Guarantees do RTC offer?

RTC are Property Care Association (PCA) members and are therefore able to offer the option of a long term insured guarantee for Dry Rot treatment issued by the GPI.

Because the GPI guarantee is genuine insurance it provides protection if the contractor ceases to trade for any reason and is transferable to the new owners if you sell your property. See www.gptprotection.co.uk for more information.
