Cavity insulation top-up for Helensburgh properties

Helensburgh is among the towns we cover in Argyll and Bute, alongside Dunoon and Oban. Helensburgh is one of the main towns we cover in Argyll and Bute.

If a wall in Helensburgh 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 Helensburgh 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 Argyll and Bute 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 Helensburgh 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.
