Cavity insulation for new builds and extensions for Keighley properties
Our West Yorkshire coverage takes in Keighley (BD21) and nearby Shipley, Guiseley and Bradford. It is about 16 miles west of Leeds.
Where a Keighley property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. A suitable wall in Keighley 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. West Yorkshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
In terms of approvals, in Keighley filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

What we work from
Your architect's or designer's specification and the energy calculation for the job. We match the product, thickness and fixing to that spec, keep cavities clean as the walls rise, and fit cavity trays, closers and stop ends where shown so the building control inspection goes smoothly.
