Damp investigation after 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.
Damp in an insulated Perth home is not always the insulation's fault, so the diagnosis comes before any extraction. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Perth properties, so you can choose who fixes them.
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.
In terms of approvals, if cavity wall insulation follows in Perth, no building warrant is needed for insulation within a wall, but the work must meet the building standards.
Rules in Scotland
