Cavity insulation top-up for Lerwick properties
If your property is in Lerwick or the ZE1 district, it is within our Highlands and Islands coverage. Island addresses are surveyed by arrangement.
A suitable wall in Lerwick is usually filled in a single day from outside, with drill holes made good to match the pointing. Where a Lerwick property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Before any material is chosen, exposure is checked. 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.
For regulations, in Lerwick no building warrant is needed for insulation within a wall, but the work must meet the building standards.

When a top-up is not enough
If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.
