Skylight repairs & leak fixes for Castlereagh: the essentials
Skylight repairs & leak fixes in Castlereagh means leak tracing, resealing, actuator repairs and glass replacement. We cover the BT5 district and the rest of County Down, with a survey before any price is fixed.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Typical uses for skylight repairs & leak fixes include leaks, condensation, misted units and failed actuators.
We work across County Down, including Castlereagh, and in neighbouring towns such as Belfast and Newtownabbey. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Castlereagh
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
