Remove and refill for March properties

We cover March and the PE15 postcode district, including nearby Wisbech, Ely and Peterborough. It is roughly 24 miles north of Cambridge.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for March properties, so you can choose who fixes them. If your March 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 Cambridgeshire 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, if cavity wall insulation follows in March, 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.
