How to Remove Cavity Wall Insulation

How a cavity wall insulation is removed depends on the insulation material within the walls.

If the insulation is made of wool, it can be simply extracted. All that is required is big insulation extraction vacuum.

If the insulation is solid, it’s not so simple. To extract solid insulation, the solid insulation will need to be broken up into crumbles so it can be removed safely. To do this, high pressure air is blown within the wall cavity through injection holes and then it is extracted with the sepcialised vacuum.

The Removal process

  • First, a number of external bricks are removed along the bottom of the wall (this allows for the material to be extracted later on).
  • Now holes are drilled in to the wall in the affected area. This is to allow high-pressured air to be blown into the cavity, this crumbles the insulation allowing it to move freely within the cavity.
  • The crumbled defective insulation is then vacuumed from bottom holes using specialist machinery.
  • The cavity is inspected to ensure all contaminated or damaged insulation was cleared
  • All holes are filled and brickwork is restored

Cavity Wall Insulation Issues and Claims

Since the late 90s, millions of properties in the UK have been insulated with cavity wall insulation. Most of these CWI installations will have been suitable for the property and carried out correctly.

However, it has come to light that hundreds of thousands of homes have had cavity wall insulation installed incorrectly or installed to unsuitable properties. Many were installed without following the CIGA (Cavity Insulation Guarantee Agency) best practice and manufacturer’s cavity wall insulation installation guidelines.

As a result, for many properties the cavity wall insulation is causing more harm than good. Many homes are now experiencing damp, condensation, rotten woodwork and failing wall ties due to incorrectly installed insulation. This can damage the value of the property, interior decorations and furnishings. Also, the mould can be detrimental to people living at the property.

How has this happened?

  • Poor regulation and auditing
  • Poor surveying standards
  • Poor installation practices
  • Poor suitability assessments
  • Poor product choice by installers
  • Poor record keeping and administration
  • Poor training and monitoring
  • Inadequate guarantees and compliance processes

Common Cavity Wall Insulation Problems:

  • Damp Interior Walls
  • Rotten Woodwork
  • Blocked Air Vents
  • Damaged Brickwork
