Extensions such as garage conversions will often require supplementary damp proofing to be added during the conversion, as the pre-existing garage will often have a single skin design for walls and floors, which was not manufactured to be in accordance with building regulations for habitable rooms. This damp proofing will have to be added to walls and floors. Furthermore, the roofing of the garage conversion will need water proofing. The damp proofing for the floor of the garage conversion will usually be achieved by using a damp proof membrane. This membrane is available 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 if the floor will be a solid or a floating floor. In some garages, the walls have already been damp proofed, but this might have to be improved as part of the conversion in order to meet current building regulations. The walls should be damp proofed to be able to safeguard the brickwork from rotting slowly as moisture sets in. This is accomplished by either applying 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 will need to comply with, and so is it important 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

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.
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.
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.
