Damp investigation after cavity insulation for Hexham properties
We cover Hexham and the NE46 postcode district, including nearby Morpeth and Cramlington. It is roughly 25 miles south-west of Blyth.
Damp in an insulated Hexham home is not always the insulation's fault, so the diagnosis comes before any extraction. If your Hexham installation has a guarantee, we check it first; the guarantee route may cover the work.
Local weather affects which walls can be filled. Northumberland 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.
For regulations, if cavity wall insulation follows in Hexham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
