Cavity insulation top-up for Thurso properties
We cover Thurso and the KW14 postcode district, including nearby Kirkwall.
Where a Thurso property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Thurso properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Every elevation is judged on its own exposure. 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.
As for paperwork, in Thurso 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.
