We apply cork spray render systems across Chester — typically over sound existing render where the owner wants a breathable, slightly insulating, crack-bridging finish.
Why Cork Spray in Chester?
Highly flexible — cork's natural elasticity bridges minor cracks where rigid renders would split.
Local context: Chester, Cheshire
Heritage stone and brick in the conservation core, mature Edwardian and 1930s semis through Hoole and Upton — careful detail matching matters here. Sheltered Dee valley climate, but high humidity favours breathable finishes. We cover the full Cheshire area from CH1 outwards, including Hoole, Boughton, Upton, Saltney, Christleton and the wider postcodes (CH1, CH2, CH3, CH4). Most Chester jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Chester Cathedral, and the typical substrates we'll find on the wall.
Benefits
- Sound-dampening characteristics on some substrates.
- Flexible — bridges hairline cracks rather than splitting at them.
- Vapour-open — safe for older solid-wall properties.
- Modest insulating value — a useful thermal bonus.
- Bonds to wood, metal and painted surfaces.
- Self-coloured, no paint cycle.
Local considerations
- Cost per m² is higher than standard render — but the specialist properties justify it on the right job.
- Cork spray is a specialist system — not all renderers can apply it properly.
- It's not a full EWI substitute; if you need significant U-value uplift, go EWI.
- Substrate prep and primer are non-negotiable — skipping them is the most common failure mode.
- Spray application means careful overspray containment in Chester's tighter streets.
Our process in Chester
- Survey — substrate assessment, suitability check, sample on the wall.
- Scaffold or tower access depending on height.
- Substrate prep — clean, repair, prime with system primer.
- Spray-apply base coats per manufacturer spec.
- Spray finish coats to required thickness in chosen colour.
- Snag, clean, scaffold down.

Frequently asked questions
Can cork spray solve damp?
Cork is vapour-open, which can help with cold-bridging condensation. It doesn't fix rising or penetrating damp on its own.
Is cork spray render worth it in Chester?
On the right substrate and use case — yes. Especially on flexible / movement-prone substrates, on wood or metal, or where breathability is critical.
Does cork spray insulate?
It has modest insulating value — useful, but not a substitute for EWI if you need significant heat-loss reduction.
Can you spray cork over existing render?
Over sound existing render, yes — with proper prep and primer. Over failing render, no — strip first.
What colours are available?
A wide palette — sample colours brought to survey and applied on the wall for sign-off.
How long does cork spray last?
20+ years with proper substrate prep and system application.

Cork spray is a specialist product that shines in specific Chester situations. Free survey and an honest recommendation either way.
