What does skylight replacement in Castle Douglas involve?
Skylight replacement in Castle Douglas means replacing tired domes and failed glass with a modern rooflight. We cover the DG7 district and the rest of Dumfries and Galloway, with a survey before any price is fixed.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
Castle Douglas sits about 14 km from Kirkcudbright and 25 km from Dumfries, and we cover the whole DG7 postcode district and the roads in between.

Planning, building control and Castle Douglas
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 3.3 W/m²K. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.

We remove it from site and recycle what can be recycled.
