Cavity wall insulation for landlords for Sevenoaks properties

Sevenoaks is among the towns we cover in Kent, alongside Tonbridge, Swanley and Tunbridge Wells. It is roughly 14 miles west of Maidstone.

Blocks of flats in Sevenoaks are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Sevenoaks, we survey in batches and return a result sheet and fixed price per address.

Wind-driven rain is the first thing the surveyor weighs up. 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.

As for paperwork, in Sevenoaks filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
