Extensions such as garage conversions will usually require additional damp proofing to be added as part of conversion, as the pre-existing garage typically has a single skin design for walls and floors, which was not built to be in accordance with building regulations for habitable rooms. This damp proofing will need to be put into walls and floors. Moreover, the roofing of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will in most cases be performed by using 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, underneath the new floor, or as part of both, depending on if the floor will be a solid or a floating floor. In a few garages, the walls have been damp proofed, but this might need to be updated as part of the conversion to be able to adhere to current building regulations. The walls should be damp proofed in order to protect the brickwork from rotting slowly as moisture sets in. This is carried out 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 an important part of the building regulations that the garage conversion should adhere to, and so is it necessary to make sure that your garage conversion employs 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
