Extensions including garage conversions will typically require additional 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 designed to be in accordance with building regulations for habitable rooms. This damp proofing should be put into walls and floors. Moreover, the roofing of the garage conversion will require water proofing. The damp proofing for the floor of the garage conversion will in most cases be achieved by employing 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 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 will have already been damp proofed, but this may have to be improved as part of the conversion in order to comply with current building regulations. The walls should be damp proofed in order to protect 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 present in the garage. Damp proofing is a part of the building regulations that the garage conversion will need to comply with, and so is it necessary to ensure 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.
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.
