Extensions such as garage conversions will often require extra damp proofing to be installed through the conversion, as the existing garage typically has 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 should be added to walls and floors. In addition, the roof of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will often 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 pre-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 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 to be able to safeguard the brickwork from rotting gradually as moisture sets in. This is done by either utilising 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 should adhere to, and so is it necessary 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

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.
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!
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.
