Extensions including garage conversions will typically require extra damp proofing to be added as part of conversion, as the pre-existing garage will often have a single skin design for walls and floors, which was not built to conform to building regulations for habitable rooms. This damp proofing will have to be put into walls and floors. Additionally, the roof of the garage conversion will need water proofing. The damp proofing for the floor of the garage conversion will most likely be achieved by by using a damp proof membrane. This membrane is available in either solid or liquid form. The damp proof membrane will be placed down either on top of the pre-existing concrete floor, below the new floor, or as part of both, depending on whether the floor will be a solid or a floating floor. In a few garages, the walls will have already been damp proofed, but this may need to be updated as part of the conversion to be able to adhere to 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 performed by either making use of damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already in the garage. Damp proofing is an important part of the building regulations that the garage conversion will need to comply with, and so is it important to make sure that your garage conversion incorporates suitable damp proofing methods.

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.
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.
