Remove and refill for Potters Bar properties
If your property is in Potters Bar or the EN6 district or nearby Borehamwood, Hatfield and Cheshunt, it is within our Hertfordshire coverage. It is roughly 7 miles south-east of St Albans.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Potters Bar properties, so you can choose who fixes them. If your Potters Bar installation has a guarantee, we check it first; the guarantee route may cover the work.
Wind-driven rain is the first thing the surveyor weighs up. Much of Hertfordshire 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, if cavity wall insulation follows in Potters Bar, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

Why refill at all?
Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
