Dunoon: walls, weather and approvals
We also cover Greenock and Helensburgh, close to Dunoon. Dunoon sits around 8 miles from Helensburgh. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Argyll and Bute fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
For period homes in Dunoon, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

Planning and building control in Scotland
For Dunoon properties, flats and tenements need planning permission for external insulation, and a noticeable change of finish on a house often does too under Scottish rules.
Over-cladding work in Scotland often needs a building warrant from the council's building standards service, with Section 6 of the Technical Handbooks setting insulation benchmarks.
What about listed buildings and conservation areas?
EWI on a listed building needs listed building consent and is often refused where the outside appearance matters. In conservation areas, rendering or cladding a house normally needs planning permission. Wood fibre and lime are more likely to be acceptable than foam and acrylic, but the council decides. We check before quoting.

Wood fibre EWI in Dunoon: questions
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Is wood fibre worth the extra cost?
On older solid walls the main benefit is moisture safety rather than raw U-value. If the wall needs to breathe, the cheaper option can cost more later.
Can wood fibre go on a stone wall?
Yes, after levelling. Rubble stone is often uneven, so a levelling coat or adapted fixing method is used first.
Do you cover Dunoon?
Yes — we survey and quote wood fibre external wall insulation in Dunoon (PA23) and nearby Greenock, Helensburgh and Clydebank, with a fixed written price before any work starts.
