Extensions including garage conversions will usually require extra damp proofing to be added during the conversion, as the pre-existing garage normally has a single skin design for walls and floors, which was not designed to conform to building regulations for habitable rooms. This damp proofing will have to be put into walls and floors. Moreover, the roofing of the garage conversion will need 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 can come in either solid or liquid form. The damp proof membrane will be put down either on top of the 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 will have already been damp proofed, but this might need to be improved as part of the conversion to be able to comply with current building regulations. The walls will need to be damp proofed to be able to safeguard the brickwork from rotting gradually as moisture sets in. This can be done by either employing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already present 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 employs 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

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!
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.
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.
