Extensions including garage conversions will typically require extra damp proofing to be added through the conversion, as the 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 have to be added to walls and floors. Additionally, the roof of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will most likely be achieved by utilising a damp proof membrane. This membrane can 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 a few garages, the walls have been damp proofed, but this may need to be improved as part of the conversion in order to comply with current building regulations. The walls will need to be damp proofed in order to protect the brickwork from rotting slowly as moisture sets in. This can be done 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 important part of the building regulations that the garage conversion will need to adhere to, therefore is it necessary to ensure that your garage conversion makes use of suitable damp proofing methods.
The average cost of Damp proofing is £1500. Costs vary based upon the materials and the organisation selected. The upper price range can be as high as £1725. The material costs are in general about £375

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.
