No roughcaster listed in Sanquhar yet.

A roughcaster applies a textured external finish to buildings - the traditional Scottish harling that protects stone and blockwork walls from the weather while giving them a clean, uniform appearance.

Harling is one of Scotland's most common wall finishes and when it cracks, blows or starts to let in damp, getting it patched or replaced promptly prevents more expensive damage to the masonry underneath.

Ask whether they use traditional lime harling or modern cement render - on older stone buildings, lime-based finishes allow the walls to breathe and avoid the moisture problems that cement can cause.

Sanquhar is a small town in upper Nithsdale, sitting on the River Nith between the Lowther Hills and the Southern Uplands.

The town is home to what claims to be the oldest post office in the world - Sanquhar Post Office has been in continuous use since 1712.

Sanquhar has a Covenanting history - the Sanquhar Declarations of 1680 and 1685 were nailed to the mercat cross by Covenanters rejecting the authority of the Crown.

The town has a traditional main street, a ruined castle and a knitting pattern - the Sanquhar pattern - that is a recognised heritage craft associated with the town.

Dumfries and Galloway is the most south-westerly council area in Scotland, stretching from the English border at Gretna to the Mull of Galloway - the southernmost point in Scotland - and from the Solway Firth coast inland to the hills of the Southern Uplands.

Dumfries is the largest town and administrative centre, a handsome red sandstone burgh on the River Nith where Robert Burns spent the last years of his life and is buried in St Michael's Kirkyard.

The region divides naturally into three historic areas: Dumfriesshire to the east, Kirkcudbrightshire (the Stewartry) in the centre and Wigtownshire to the west - each with its own character, landscape and loyalties.

The Galloway coast and countryside have a mild climate influenced by the Gulf Stream, fertile farmland, dark-sky reserves and a string of small harbour towns that attract artists, writers and visitors drawn to the quiet and the landscape.

Despite its size, the region is one of the most sparsely populated in Scotland - a place where community is strong, the pace is slower and the landscape ranges from river valleys and rolling farmland to wild moorland and rocky coastline.
