Before we quote in Lerwick
We cover Lerwick and the wider Orkney, Shetland and the Western Isles; island and remote addresses are surveyed by arrangement. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Orkney, Shetland and the Western Isles 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.
Where a property in Lerwick is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Approvals in Scotland
Internal insulation rarely needs planning permission; listed buildings need consent for internal changes.
Scotland's building standards cover changes to external wall construction; we check whether your job in Lerwick needs a warrant.
What are the risks with internal insulation?
Insulating inside makes the masonry colder, so moisture risk rises. Weak points are where floor joists bear into the wall, window reveals and corners. A condensation risk check for the build-up, a continuous vapour control layer where specified, and returning insulation into reveals deal with most of it.

Internal wall insulation in Lerwick: questions
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.
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
