Cavity wall insulation for Hull properties
We cover Hull and the HU1 postcode district, including nearby Beverley, Goole and Bridlington. Hull is one of the main towns we cover in the East Riding of Yorkshire.
Where a Hull property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Hull properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Wind-driven rain is the first thing the surveyor weighs up. Much of the East Riding of Yorkshire 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 the rules side, in Hull filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

What happens on the day?
Holes of around 22mm are drilled in the mortar joints in a set pattern, roughly a metre apart. The insulation is blown in from the bottom up until each section is full, then every hole is filled with colour-matched mortar. Air bricks and flues are protected, and a cavity barrier is fitted where your wall joins a neighbour's.
