Party wall cavity insulation for Lowestoft properties
If your property is in Lowestoft or the NR32 district or nearby Stowmarket, Ipswich and Felixstowe, it is within our Suffolk coverage. It is about 39 miles north-east of Ipswich.
Most Lowestoft houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. Where a Lowestoft property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Local weather affects which walls can be filled. Much of Suffolk 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.
On compliance, in Lowestoft 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 Lowestoft
- Loft inspection and borescope check
- Certified fill to the separating wall
- Neighbour notification guidance
