How we approach skylight replacement in Limavady
Skylight replacement in Limavady means replacing tired domes and failed glass with a modern rooflight. We cover the BT49 district and the rest of County Londonderry, with a survey before any price is fixed.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. In Limavady, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.

Planning and building rules for Limavady
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. 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.

Questions about skylight replacement in Limavady
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
