Limavady, Londonderry
External Wall Insulation in Limavady
EWI systems that insulate solid walls externally and finish them in a warranted render topcoat.
External Wall Insulation in Limavady is work we take on regularly, and the Londonderry housing stock is a big part of why.
Across Londonderry, Victorian terraces, harled cottages and exposed north-coast housing dominates, and driving rain and salt on north-coast properties is what we are called out to most often.
Limavady sits in a part of the UK that gets wet with severe Atlantic exposure on the north coast — worth factoring into any render decision. The north coast around portstewart takes direct atlantic weather, and dash finishes substantially outperform smooth render there.
When external wall insulation is the right call. Choose EWI on solid-wall, no-fines or non-traditional construction where you want a genuine thermal upgrade rather than just a new finish.

FAQs
External Wall Insulation in Limavady
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
Will you need scaffolding?
For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.
How long before I can paint new render?
Through-coloured systems need no painting at all. Sand and cement should cure for around 28 days before masonry paint goes anywhere near it.
Do you take a deposit?
For most domestic jobs we take a deposit to cover materials and scaffold, with the balance on completion. Terms are set out clearly in the written quote.
