Skylight repairs & leak fixes in Lisburn: what is involved?
For Lisburn homes and buildings we offer skylight repairs & leak fixes: leak tracing, resealing, actuator repairs and glass replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Skylight repairs & leak fixes suit rooflights that have stopped opening or started dripping.
Neighbouring towns include Belfast (11 km) and Castlereagh (11 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Lisburn
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. 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.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. Extensions follow a 25% glazing allowance in Technical Booklet F1.
Read the planning permission guide before you commit to a design.

Common questions
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
How do I book a survey in Lisburn?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Lisburn?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
