Remove and refill in Brentwood

Remove and refill extracts unsuitable or failed cavity insulation, fixes whatever caused the problem, and refills the cavity with a certified system that suits the wall's exposure and condition, so you keep the energy saving without the damp. In Brentwood the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Remove and refill for Brentwood properties

If your property is in Brentwood or the CM14 district or nearby Billericay, Basildon and South Ockendon, it is within our Essex coverage. It is roughly 11 miles south-west of Chelmsford.

If your Brentwood installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Brentwood home is not always the insulation's fault, so the diagnosis comes before any extraction.

Before any material is chosen, exposure is checked. Much of Essex 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 Brentwood, 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.
