Party wall cavity insulation for Rawtenstall properties
Our Lancashire coverage takes in Rawtenstall (BB4) and nearby Accrington, Burnley and Darwen. It is about 17 miles east of Preston.
Most Rawtenstall houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. A suitable wall in Rawtenstall is usually filled in a single day from outside, with drill holes made good to match the pointing.
Local weather affects which walls can be filled. Parts of Lancashire 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 Rawtenstall filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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 Rawtenstall
