Local considerations in Dumfries
We cover Dumfries and the wider Dumfries and Galloway; island and remote addresses are surveyed by arrangement. South West Scotland has stone and harled houses, coastal towns and post-war council housing.
Parts of Dumfries and Galloway 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.
We plan internal insulation in Dumfries homes room by room so you keep the rest of the house usable.

Permissions in Scotland
Internal insulation rarely needs planning permission; listed buildings need consent for internal changes.
Where a building warrant is needed for Dumfries work, it's obtained before installation starts, and the quote says who arranges it.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.

Internal wall insulation in Dumfries: questions
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
Do you cover Dumfries?
Yes — we survey and quote internal wall insulation in Dumfries (DG1); island and remote addresses are surveyed by arrangement, with a fixed written price before any work starts.
