Remove and refill for Coleraine properties

Coleraine sits in County Londonderry, roughly 27 miles east of Derry. We work across the BT52 district, including nearby Limavady, Magherafelt and Derry.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Coleraine properties, so you can choose who fixes them. We never cold-call in Coleraine or anywhere else, and we do not work with doorstep claims companies.

Every elevation is judged on its own exposure. Parts of County Londonderry 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.

For regulations, if cavity wall insulation follows in Coleraine, inserting cavity wall insulation needs a building control application to the council before work starts.

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.

What is included in Coleraine

  • Refill with a suitable certified system
  • Diagnosis and extraction
  • Clean-cavity camera check
  • Repairs to pointing, gutters or render where needed
