What causes dry rot ?

Dry rot is the term given to brown rot decay caused by fungi that deteriorate timber in buildings and other wooden construction without an apparent source of moisture. The term is a misnomer because all wood decaying fungi need a minimum amount of moisture before decay begins. In a nutshell, dry rot is a wood destroying fungus that digests parts of the wood which give the timber strength and its structural integrity and can cause serious damage.

Dry Rot Vs Wet Rot

Both wet and dry rot timber are both associated with aggressive fungal decay. However, the main difference between the two is that Dry Rot (Serpula Lacrymans) will generally germinate and grow on timbers with a lower moisture content (upwards of 20%) than that preferred by Wet Rot (upwards of 50%). The visible fungal growth is, however, distinctly different, with Wet Rot (Coniophora Puteana) the mycelia is usually more black/brown in colour (in certain situations it can be white, for example under linoleum) with the fruiting bodies tending to be more white/grey in colour. There are over 20 species (in the Coniophoraceae family) of types of Wet Rot fungus and we have generalised here describing the most common, Coniophora Puteana. Whichever you problem, dry rot / wet rot timbers, we will carry out the correct timber preservation procedures to stop your problem and put in place the correct structural repairs.

Installed Kair Flat Ventilation System, “Work was carried out efficiently and neatly and clearly every effort had been made to clean up afterwards. The work took longer than scheduled - into second day - due to difficulty boring holes through re-inforced concrete (not anticipated) but this did not inconvenience me as flat is unoccupied at present. Allround a very friendly and helpful workforce. Very satisfied with outcome and would recommend this firm.”

Fixing a damp problem and re-plastering, “We had a damp problem in our hallway and a number of contractors looked and quoted for the work. Top Joints were the only company to properly look into what had caused the problem and did not automatically assume we had rising damp (old house, no DPC). It turns out a leaking stop cock was causing a localised problem, yet everyone else tried to sell us a DPC. Once the real problem had been identified, Top Joints' quote and plan of remedial action was very competitive and we were happy to give them the work. Everyone we dealt with was courteous and polite and queries were responded to quickly and professionally. I would recommend Top Joints.”

Disruption was minimal despite working in three separate rooms and the loft. This included cutting through three ceilings and fitting inlet and outlet vents through external walls. Kept informed of progress during the day. Quickly resolved small technical issue after installation. Would thoroughly recommend this company..”
