Party wall cavity insulation for Haywards Heath properties

Our West Sussex coverage takes in Haywards Heath (RH16) and nearby Burgess Hill, Crawley and East Grinstead. It is roughly 9 miles south-east of Crawley.

If a wall in Haywards Heath 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 Haywards Heath, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.

Local weather affects which walls can be filled. West Sussex 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 Haywards Heath filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

What we need from you and your neighbour

The cavity is shared, so we talk you through notifying your neighbour before work. Filling is done from your side, usually through the loft. The survey confirms the wall is a cavity wall and not solid masonry, and checks for cables, flues and any gaps that would let fill escape.
