Rising damp is moisture present in your walls as a result of water in the ground underneath or next to your walls rising up through the fabric of the wall, whether it be brick, block or stone. The water travels upwards through the wall as a result of capillary action (where water is sucked through a small opening such as a tube or hole) through the tiny holes in the brick or stone. The water stops rising at a height where gravity counteracts the upwards force of the capillary action. This rising damp usually reaches a maximum height of 1.2m, but the effects of the damp, such as salt deposits, may be seen higher up due to the presence of non-breathing wall coverings such as vinyl wallpaper and non breathing plasters, renders and paints
Condensation starts as moisture in the air, usually produced by cooking, washing, or drying clothes indoors on radiators.When it hits cool surfaces such as walls, mirrors, wall tiles and windows it condenses and forms water droplets. The moist air rises when it is warm and often ends up on ceilings and in upstairs rooms and then it forms mould.
The system is installed in the roof space of the home and the ceiling located louvre is unobtrusive enough to fit in with the decor of any home. Controls:
Condensation, mildew, mould and dampness Health: Creates a fresher, cleaner, living environment for you and your family Energy Efficient: Low running costs, better utilisation of existing heating Security: Gives curtains, carpets and paintwork a longer life.
Dry-rot fungus is often thought of as a building cancer, rampaging through buildings and rapidly destroying any timber in its path. The fungus, which thrives in moist unventilated conditions, will penetrate brickwork to get to more timber and can cause widespread destruction of structural timbers, skirting boards and door frames, and wood flooring.
In short, the fungus can be thought of as 'living in masonry and eating wood', and because the fungus thrives in damp, unventilated conditions, it can occur in the areas of a property that are not often seen, such as floor voids, or behind timber panelling, so damage may be extensive before the attack is discovered.
Wood with wet rot has a typically soft and spongy feel and often looks darker than surrounding healthy wood. If the wood is painted it can mask the decay and appear quite healthy; it's only by poking with a screwdriver you'll discover if it's affected. On walls the fungus manifests with brown/black strands in a fern-like pattern.
Woodworm refers to the larvae of any wood-boring beetle, rather than one particular species. In the UK, the most common are the Common Furniture Beetle (Anobium punctatum).
Small round holes in your woodwork, similar to the holes in a dart board.
Fine, powdery dust around these holes (this is known as frass).
Crumbly edges to boards and joists.
Adult beetles emerging from the holes or present around the house.
Faulty wall ties can cause horizontal cracks and bulges to appear in your brickwork and even your outer cavity wall to completely collapse. Cavity wall ties are an essential part of any building. Their job is to tie together the visible protective outer cavity of brickwork or blockwork of a building to its structural and load bearing inner masonry skin.
