Extensions including garage conversions will typically require additional damp proofing to be installed through the conversion, as the pre-existing garage normally has a single skin design for walls and floors, which was not built to conform to building regulations for habitable rooms. This damp proofing should be added to walls and floors. In addition, 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 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 whether 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 in order to safeguard the brickwork from rotting slowly as moisture sets in. This is accomplished by either implementing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already in the garage. Damp proofing is an integral part of the building regulations that the garage conversion should comply with, therefore is it important to ensure that your garage conversion incorporates suitable damp proofing methods.

These include peeling paint and wallpaper, crumbling plaster, mould growth, black spots or spores on walls and ceilings, and rotting skirting boards and flooring.
