Party wall cavity insulation for Ashford properties
If your property is in Ashford or the TN24 district or nearby Faversham, Canterbury and Folkestone, it is within our Kent coverage. It is about 17 miles south-east of Maidstone.
If a wall in Ashford is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. For semi-detached and terraced homes in Ashford, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Before any material is chosen, exposure is checked. Much of Kent 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.
In terms of approvals, in Ashford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

Why a party wall loses heat
Many semi-detached and terraced homes built with cavity separating walls have that cavity open to the loft. Air moves up the cavity and out at the top, a loss sometimes called the party wall bypass. Filling the cavity and sealing the top stops it.
