Party wall cavity insulation in Perth

Perth homeowners, landlords and managing agents can book party wall cavity insulation with a free survey first. Party wall insulation fills the cavity in the separating wall between two houses, which otherwise lets warm air rise up and out through the loft.

Party wall cavity insulation for Perth properties

Perth sits in Tayside, roughly 18 miles west of Dundee. We work across the PH2 district, including nearby Dundee, Forfar and Arbroath.

A suitable wall in Perth is usually filled in a single day from outside, with drill holes made good to match the pointing. Most Perth 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.

Every elevation is judged on its own exposure. Tayside 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 Perth no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Funding in Scotland

In Scotland, Home Energy Scotland is the route to the Home Energy Scotland Grant and Loan and Warmer Homes Scotland.

What we need from you and your neighbour

The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.

What is included in Perth

  • Neighbour notification guidance
