Party wall cavity insulation for Leighton Buzzard properties
Leighton Buzzard is among the towns we cover in Bedfordshire, alongside Dunstable, Ampthill and Luton. It is about 17 miles south-west of Bedford.
If a wall in Leighton Buzzard 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 Leighton Buzzard, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Wind-driven rain is the first thing the surveyor weighs up. Much of Bedfordshire 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, in Leighton Buzzard 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.
What is included in Leighton Buzzard
