Cavity wall insulation for Castleford properties
We cover Castleford and the WF10 postcode district, including nearby Pontefract, Lofthouse and Wakefield. It is around 9 miles south-east of Leeds.
Most Castleford 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 Castleford is usually filled in a single day from outside, with drill holes made good to match the pointing.
Exposure matters for every cavity wall. 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.
On compliance, in Castleford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

What happens on the day?
Holes of around 22mm are drilled in the mortar joints in a set pattern, roughly a metre apart. The insulation is blown in from the bottom up until each section is full, then every hole is filled with colour-matched mortar. Air bricks and flues are protected, and a cavity barrier is fitted where your wall joins a neighbour's.
