Extensions such as garage conversions will usually require supplementary damp proofing to be added 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 will need to 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 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 placed down either on top of the pre-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 have to be updated as part of the conversion in order to meet 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 performed by either employing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls already present in the garage. Damp proofing is a part of the building regulations that the garage conversion should comply with, therefore is it necessary to make sure that your garage conversion employs appropriate 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.
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.
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.
