Cavity insulation top-up for Forfar properties

If your property is in Forfar or the DD8 district or nearby Dundee and Arbroath, it is within our Tayside coverage. It is around 13 miles north of Dundee.

A suitable wall in Forfar is usually filled in a single day from outside, with drill holes made good to match the pointing. Where a Forfar property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.

Local weather affects which walls can be filled. 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.

As for paperwork, in Forfar 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.

When a top-up is not enough

If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.
