Cavity insulation for new builds and extensions for Pontefract properties
Pontefract sits in West Yorkshire, around 12 miles south-east of Leeds. We work across the WF8 district, including nearby Castleford, Wakefield and Lofthouse.
Pontefract properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. A suitable wall in Pontefract 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 Pontefract filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

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.
