Cavity insulation for new builds and extensions for Lytham St Annes properties
Our Lancashire coverage takes in Lytham St Annes (FY8) and nearby Blackpool, Thornton-Cleveleys and Preston. It is roughly 12 miles west of Preston.
Most Lytham St Annes 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. Where a Lytham St Annes 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 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.
On the rules side, in Lytham St Annes filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
