Cork spray is a modern, breathable, flexible insulating render finish that's gaining serious traction in Lancaster — especially on properties where standard cement and silicone aren't quite right.
Why Cork Spray in Lancaster?
Bonds to substrates that conventional render struggles with — wood, metal, painted surfaces.
Local context: Lancaster, Lancashire
Stone-built Victorian terraces in the historic core, postwar pebbledash estates on the outskirts, plus coastal stock around Morecambe Bay. Bay-front exposure delivers salt-laden wind and heavy rain — coastal-grade silicone is the sensible spec. We cover the full Lancashire area from LA1 outwards, including Morecambe, Heysham, Halton, Galgate, Bowerham and the wider postcodes (LA1, LA2). Most Lancaster jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Lancaster Castle, and the typical substrates we'll find on the wall.
Benefits
- Excellent on flat-roof upstands, dormers and complex detailing.
- 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.
Local considerations
- Substrate prep and primer are non-negotiable — skipping them is the most common failure mode.
- Spray application means careful overspray containment in Lancaster's tighter streets.
- 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.

Frequently asked questions
Is it noisy or disruptive?
Spray application is quick and controlled, but we contain overspray carefully — especially on terraced streets in Lancaster.
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 Lancaster?
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.
