Damp Proofing in Knaresborough

Extensions including garage conversions will usually require additional damp proofing to be installed as part of conversion, as the existing garage routinely has a single skin design for walls and floors, which was not manufactured to conform to building regulations for habitable rooms. This damp proofing should be put into walls and floors. Moreover, the roof of the garage conversion will need water proofing. The damp proofing for the floor of the garage conversion will in most cases be achieved by employing a damp proof membrane. This membrane can come in either solid or liquid form. The damp proof membrane will be placed down either on top of the 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 a few garages, the walls have already been damp proofed, but this might need to be improved as part of the conversion to be able to adhere to current building regulations. The walls will need to be damp proofed to be able to protect the brickwork from rotting slowly as moisture sets in. This is 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 a part of the building regulations that the garage conversion will need to comply with, therefore is it necessary to ensure that your garage conversion employs appropriate damp proofing methods.

Knaresborough is a historic market town, spa town and civil parish in the Borough of Harrogate, North Yorkshire, England. Historically an area of the West Riding of Yorkshire, it is positioned on the River Nidd, 4 miles east from the centre of Harrogate. The town is detailed in the Domesday Book of 1086 as 'Cenheard's fortress', with the name of the area experiencing a number of changes over the next few centuries. The advancement of the town commenced around 1100, when it started to offer a market and appeal to traders to service the castle. The town was not awarded a royal charter to certify its status as a market town up until 1310 by Edward II. A market continues to be held every Wednesday in the market square throughout the year. There are several landmarks dispersed across the town that attract frequent visitors. Some examples include the remains of Knaresborough Castle, the House in the Rock, the railway viaduct over the River Nidd, and St. Robert's Cave. Knaresborough is also the home of 'Ye Oldest Chymist Shoppe' in England, which opened in 1720, a time in which there was much suspicion about such establishments. The town is also host to a variety of social and cultural tourist attractions during the year. It has held the annual Bed Race since 1966, which is arranged by the Knaresborough Lions Club, and the Festival of Entertainment and Visual Arts (FEVA), an annual arts summer festival in the town centre, since 2001.
