Extensions such as garage conversions will usually require supplementary damp proofing to be added as part of conversion, as the pre-existing garage will typically 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 will have to be put into walls and floors. Furthermore, the roof of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will most likely be achieved by utilising 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 have been damp proofed, but this may need 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 can be performed 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 important part of the building regulations that the garage conversion should comply with, and so is it important to make sure that your garage conversion incorporates 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
