Extensions including garage conversions will often require additional damp proofing to be installed through the conversion, as the existing garage typically has a single skin design for walls and floors, which was not manufactured to conform to building regulations for habitable rooms. This damp proofing will have to be put into walls and floors. Furthermore, the roofing of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will often be achieved by using a damp proof membrane. This membrane is available in either solid or liquid form. The damp proof membrane will be put down either on top of the existing concrete floor, underneath the new floor, or as part of both, depending on if the floor will be a solid or a floating floor. In some garages, the walls have already been damp proofed, but this might need to be updated as part of the conversion in order to comply with current building regulations. The walls should be damp proofed to be able to protect the brickwork from rotting slowly as moisture sets in. This is done by either making use of damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls already present in the garage. Damp proofing is an integral part of the building regulations that the garage conversion should adhere to, therefore is it vital to ensure that your garage conversion employs appropriate damp proofing methods.

Damp is a serious problem, particularly if you live in an old property, because it can lead to structural damage. This will cost you big money and could be very dangerous, to yourself and the property. Take damp seriously and get it inspected and resolved as soon as you discover it!
There are a few visible signs of damp, although it often goes undetected. However, in older or empty properties, this made become detectable through its smell. These include peeling paint and wallpaper, crumbling plaster, mould growth, black spots or spores on walls and ceilings, and rotting skirting boards and flooring.
You should make sure that all signs of damp have gone before you redecorate your walls. If you want to paint your walls with a water-permeable emulsion paint, you can usually do this after 1 or 2 months. For other types of decoration you should wait longer.
