Extensions such as garage conversions will typically require additional damp proofing to be added during the conversion, as the pre-existing garage routinely has a single skin design for walls and floors, which was not designed to comply with building regulations for habitable rooms. This damp proofing should 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 in most cases be performed by by using a damp proof membrane. This membrane can come in either solid or liquid form. The damp proof membrane will be put down either on top of the pre-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 some garages, the walls have already 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 in order to safeguard the brickwork from rotting slowly as moisture sets in. This can be carried out by either employing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already in the garage. Damp proofing is a part of the building regulations that the garage conversion will need to adhere to, and so is it important to make sure that your garage conversion incorporates 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 Haringey is a London borough in North London, classified by some definitions as a part of Inner London, and by others as a part of Outer London. It was created in 1965 by the amalgamation of 3 former boroughs. It shares borders with six other London boroughs. Clockwise from the north, they are: Enfield, Waltham Forest, Hackney, Islington, Camden, and Barnet. Haringey covers an area of more than 11 square miles (28.5 km2). The local authority is Haringey London Borough Council.
According to population estimates from the middle of 2014, Haringey includes a permanent population of about 267541 individuals. There are about 97101 properties in Haringey. Of those, 46 per cent are owner occupied. The borough is characterised by some intense contrasts. Locations in the west, such as Highgate, Muswell Hill and Crouch End are among the most prosperous in the country. Within the east of the borough, however, some wards are classified as being amongst the most deprived 10 per cent in the country.
Haringey is also a borough of contrasts geographically. From the wooded high ground around Highgate and Muswell Hill, at 426.5 feet (130.0 m), the land falls sharply away to the flat, open low-lying land next to the River Lea in the east. A few of the more familiar nearby landmarks consist of Alexandra Palace, Bruce Castle, Jacksons Lane, Highpoint I and II, and Tottenham Hotspur Football Club.

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.
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!
