Cavity insulation top-up for Renfrew properties
If your property is in Renfrew or the PA4 district or nearby Paisley, Newton Mearns and Greenock, it is within our Renfrewshire and Inverclyde coverage. It is roughly 3 miles north-east of Paisley.
Renfrew properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. Where a Renfrew property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Exposure matters for every cavity wall. Parts of Renfrewshire and Inverclyde 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 Renfrew 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.
