Party wall cavity insulation for Renfrew properties
Renfrew sits in Renfrewshire and Inverclyde, roughly 3 miles north-east of Paisley. We work across the PA4 district, including nearby Paisley, Newton Mearns and Greenock.
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. For semi-detached and terraced homes in Renfrew, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Every elevation is judged on its own exposure. 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.
As for paperwork, in Renfrew no building warrant is needed for insulation within a wall, but the work must meet the building standards.

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.
What is included in Renfrew
