What the job covers

- Both can be done in stages, elevation by elevation or room by room
- Internal insulation suits single rooms or where the outside can't change
- Solid walls can lose heat roughly twice as fast as an insulated cavity wall
Dunoon: walls, weather and approvals
We cover Dunoon and nearby Greenock, Helensburgh and Clydebank. It's roughly 8 miles from Dunoon to Helensburgh, the largest town in Argyll and Bute. 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 Dunoon homeowners weighing external against internal insulation, the survey sets out both with prices.

Permissions 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.
External or internal — which is better?
External insulation keeps the wall warm, reduces cold bridging at floors and party walls, renews the outside, and doesn't shrink rooms — but it changes the look and needs scaffolding. Internal insulation keeps the façade unchanged and can be done room by room, but loses 50–100mm of floor space per wall and needs careful detailing to avoid condensation at joists and corners.

Solid wall insulation in Dunoon: questions
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Can I get a grant for solid wall insulation?
Some schemes cover it for eligible households — for example ECO4 until 31 December 2026, Home Energy Scotland's grant and loan, Wales' Warm Homes Nest and NI's Affordable Warmth Scheme. Each has its own eligibility and installer rules; see our grants guide.
Is solid wall insulation worth it?
For many solid-walled homes it's one of the biggest single improvements to comfort, because the walls are often the largest heat-loss area. Savings depend on the home and heating, so we don't promise a figure.
