Extensions such as garage conversions will typically require supplementary damp proofing to be installed through the conversion, as the pre-existing garage typically has a single skin design for walls and floors, which was not designed to be in accordance with building regulations for habitable rooms. This damp proofing will need to be added to walls and floors. In addition, the roof of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will usually be achieved by by using a damp proof membrane. This membrane will come 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 whether the floor will be a solid or a floating floor. In some garages, the walls have been damp proofed, but this might have to be improved as part of the conversion in order to meet current building regulations. The walls should be damp proofed to be able to safeguard the brickwork from rotting slowly as moisture sets in. This can be accomplished by either using damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already present in the garage. Damp proofing is a part of the building regulations that the garage conversion will need to comply with, therefore is it important to make sure that your garage conversion incorporates 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.
