Damp investigation after cavity insulation for Amersham properties
If your property is in Amersham or the HP7 district or nearby Chesham, Chalfont Saint Peter and Gerrards Cross, it is within our Buckinghamshire coverage. It is around 27 miles south of Milton Keynes.
Damp in an insulated Amersham 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 Amersham properties, so you can choose who fixes them.
Local weather affects which walls can be filled. Much of Buckinghamshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
For regulations, if cavity wall insulation follows in Amersham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
