Cavity wall insulation for Great Malvern properties
If your property is in Great Malvern or the WR14 district or nearby Worcester, Droitwich and Stourport-on-Severn, it is within our Worcestershire coverage. It is around 7 miles south-west of Worcester.
For semi-detached and terraced homes in Great Malvern, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. A suitable wall in Great Malvern 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. Worcestershire 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 Great Malvern 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.
