Extensions such as garage conversions will typically require supplementary damp proofing to be installed during the conversion, as the pre-existing garage will typically have 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 have to be put into walls and floors. Furthermore, the roofing of the garage conversion will require water proofing. The damp proofing for the floor of the garage conversion will in most cases be performed by employing 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 pre-existing concrete floor, below the new floor, or as part of both, depending on if the floor will be a solid or a floating floor. In a few garages, the walls have been damp proofed, but this may need to be improved as part of the conversion to be able 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 can be accomplished by either implementing 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, and so is it vital to make sure that your garage conversion employs suitable damp proofing methods.

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.
Signs of rising damp tend to be close to the ground, usually no higher than a metre. It usually works its way up walls in horizontal lines. Penetrating damp usually develops in patches and can often be much higher up. For more advice, speak to a damp proofing professional.
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.
