BlueBuild Insulation is proud to introduce their new cavity wall insulation extraction service. Our team of cavity wall extraction experts uses the very latest tools and machinery to extract defective cavity wall insulation from both domestic and commercial properties while causing minimal disturbance to the fabric of the building and the occupants.

Cavity wall insulation is the most cost-effective method of reducing fuel bills – but installed incorrectly it can cause expensive problems. It can lead to damp developing and the cost of rectifying this can outweigh the savings made. House-builders began regularly constructing properties with cavity walls from around 1920, and two decades later it became standard industry practice. But poor wall cavity insulation can cause an array of problems. Damp can lead to crumbling plaster and fungal decay, and later to more serious structural and timber erosion.

Increasingly rain-lashed winters have resulted in an increase in reports of damp issues in properties. A likely cause of damp is the bridging of the cavity by the earlier installed insulation material. Moisture penetrates into the cavities – more noticeably on weather prevailing walls – and damp gradually builds over the years as the insulation material becomes saturated.

Below is a list of materials that can be extracted by BlueBuild Insulation from cavity walls:

  • Loose and/or bonded expanded polystyrene
  • Urea Formaldehyde Insulation
  • Rockwool Mineral Fibre
  • Whitewool Glass Mineral Fibre

How is the cavity wall insulation removed?

The redundant cavity wall insulation is removed using an industrial vacuum machine. The nozzle will be positioned using the drilling pattern that was previously used for the installation of the insulation material.

The removal of material commences at the base of the property, working its way up the drilling pattern, checking that the entire cavity wall is free from insulation material.

All waste material is bagged during the extraction and no waste materials are left behind. We always clean up after ourselves and always leave your property tidy exactly as we found it.

The cavity wall extraction process takes about three days to complete for an average three-bedroom semi- detached property.
