Shoreham-by-Sea, West Sussex
External Wall Insulation in Shoreham-by-Sea
EWI systems that insulate solid walls externally and finish them in a warranted render topcoat.
Getting external wall insulation right in Shoreham-by-Sea depends far more on the substrate and the exposure than on the product name.
West Sussex is characterised by flint and brick cottages, Victorian seaside terraces and large modern developments, with salt weathering on the coastal strip and lime work on flint the recurring theme on the properties we survey.
Shoreham-by-Sea sits in a part of the UK that gets mild southern conditions with coastal salt exposure — worth factoring into any render decision. The flint villages of the south downs need lime, while the seafront strip from bognor to shoreham takes constant salt loading.
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 Shoreham-by-Sea
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
Can you render over existing render?
Sometimes, if the existing coat is completely sound and well-bonded. We hammer-test it first. Anything hollow has to come off, because covering failure just hides it.
Are you insured?
Yes — full public liability cover, and we can send the certificate before we start. We are happy to provide RAMS for commercial and contractor work.

We work UK-wide, with teams across England, Scotland, Wales and Northern Ireland. If we are not the right firm for your location we will tell you rather than waste your time.
