Extensions such as garage conversions will typically require additional damp proofing to be added through the conversion, as the pre-existing garage routinely has a single skin design for walls and floors, which was not built to conform to building regulations for habitable rooms. This damp proofing should be added to walls and floors. Furthermore, the roofing of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will usually be achieved by employing a damp proof membrane. This membrane will 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 whether the floor will be a solid or a floating floor. In a few garages, the walls have already been damp proofed, but this might need to be updated as part of the conversion to be able to comply with current building regulations. The walls should be damp proofed to be able to protect the brickwork from rotting slowly as moisture sets in. This is carried out by either implementing 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 integral part of the building regulations that the garage conversion will need to adhere to, and so 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.
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.
