Carterton, Oxfordshire
External Wall Insulation in Carterton
EWI systems that insulate solid walls externally and finish them in a warranted render topcoat.
Our external wall insulation work in Carterton starts with a free survey, because guessing at a render specification is how jobs go wrong.
Most of what we see around Carterton reflects the wider Oxfordshire pattern — Cotswold stone in the west, Georgian and Victorian in Oxford and large modern estates, and conservation-compliant lime work and high-specification finishes on period property.
Carterton sits in a part of the UK that gets a moderate inland climate — worth factoring into any render decision. The western half of the county falls within the cotswolds aonb, where finish and colour are subject to real planning scrutiny.
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 Carterton
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.
Can you match my existing render?
Usually, yes. We colour and texture match as closely as we can, though weathered render never matches a fresh batch exactly — we will be honest about how visible a patch will be.
