Remove and refill for St Albans properties

St Albans is among the towns we cover in Hertfordshire, alongside Harpenden, Hatfield and Hemel Hempstead. St Albans is one of the main towns we cover in Hertfordshire.

Where a St Albans wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. If your St Albans installation has a guarantee, we check it first; the guarantee route may cover the work.

Every elevation is judged on its own exposure. 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.

In terms of approvals, if cavity wall insulation follows in St Albans, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

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.
