Cavity insulation for new builds and extensions for Skelmersdale properties

If your property is in Skelmersdale or the WN8 district or nearby Ormskirk, Chorley and Leyland, it is within our Lancashire coverage. It is around 15 miles south of Preston.

For semi-detached and terraced homes in Skelmersdale, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. A suitable wall in Skelmersdale 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.

On compliance, in Skelmersdale filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Extensions that join an older house

Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
