Party wall cavity insulation in Lerwick

Looking for party wall cavity insulation in Lerwick? We survey first, name the installer, their scheme registrations and the guarantee on the quote, and only then book the work. Party wall insulation fills the cavity in the separating wall between two houses, which otherwise lets warm air rise up and out through the loft.

Party wall cavity insulation for Lerwick properties

Our Highlands and Islands coverage takes in Lerwick (ZE1). Island addresses are surveyed by arrangement.

If a wall in Lerwick is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. A suitable wall in Lerwick is usually filled in a single day from outside, with drill holes made good to match the pointing.

Wind-driven rain is the first thing the surveyor weighs up. Parts of the Highlands and Islands face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On compliance, in Lerwick no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Funding in Scotland

In Scotland, Home Energy Scotland is the route to the Home Energy Scotland Grant and Loan and Warmer Homes Scotland.

What we need from you and your neighbour

The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.
