Party wall cavity insulation for Saddleworth properties
If your property is in Saddleworth or the OL3 district or nearby Oldham, Stalybridge and Ashton-under-Lyne, it is within our Greater Manchester coverage. It is roughly 11 miles north-east of Manchester.
Most Saddleworth 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. If a wall in Saddleworth is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Before any material is chosen, exposure is checked. Greater Manchester 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 Saddleworth filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Why a party wall loses heat
Many semi-detached and terraced homes built with cavity separating walls have that cavity open to the loft. Air moves up the cavity and out at the top, a loss sometimes called the party wall bypass. Filling the cavity and sealing the top stops it.
What is included in Saddleworth
- Certified fill to the separating wall
- Loft inspection and borescope check
