Extensions such as garage conversions will often require supplementary damp proofing to be installed during the conversion, as the existing garage normally has a single skin design for walls and floors, which was not manufactured to conform to building regulations for habitable rooms. This damp proofing will have to be put into 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 performed by employing a damp proof membrane. This membrane is available 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 if the floor will be a solid or a floating floor. In a few garages, the walls have already been damp proofed, but this might have to be updated as part of the conversion to be able to adhere to current building regulations. The walls should be damp proofed to be able to protect the brickwork from rotting gradually as moisture sets in. This is accomplished by either using 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 should comply with, and so is it important 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

The London Borough of Camden is a borough in north west London, and forms a part of Inner London. The southern reaches of Camden form a part of central London. The borough was created in 1965 from the previous area of the metropolitan boroughs of Hampstead, Holborn, and St Pancras, which had formed a part of the County of London. The borough was named after Camden Town, which had gained its name from Charles Pratt, 1st Earl Camden in 1795. The transcribed diaries of William Copeland Astbury, just lately made accessible, describe Camden and the surrounding places in great detail from 1829 to 1848. The local authority is Camden London Borough Council.
Neighbouring areas are the City of Westminster along with the City of London to the south, Brent to the west, Barnet and Haringey to the north and Islington towards the east. The borough covers a total area of around 8.4 square miles. You can find 162 English Heritage blue plaques within the borough of Camden representing the lots of diverse personalities which have lived there. The borough is also home to a wide number of attractions, for instance the Bloomsbury Theatre, Camden Market, the Foundling Museum and Kenwood House.
All bus services are operated by Transport for London, and buses serve each suburb within the borough. 3 of the fourteen central London's railway terminals are situated within the borough, which are Euston, St. Pancras International and King's Cross.

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.
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.
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.
