Remove and refill in Lancashire

Remove and refill is available throughout Lancashire, from Preston to Burnley and Blackburn, with the price agreed first. 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.

We cover 18 towns in Lancashire, including Preston, Burnley, Blackburn, Blackpool, Morecambe and more.

Wind-driven rain is the first thing the surveyor weighs up. Parts of Lancashire face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

We never cold-call in Lancashire or anywhere else, and we do not work with doorstep claims companies. Where a Lancashire 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.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.
