  • What types of insulation can be removed?

    We can remove all types, such as fiber glass, Polystyrene beads or granules. The industrial vacuum system we deploy is much stronger than an everyday home vacuum cleaner.

  • How do you dry the cavity wall out?

    We install cavity wall ventilation, this allows the walls to breath and expel damp before it becomes a problem

  • How do you see inside the cavity wall?

    We use a borescope, we will need to drill a small hole between the bricks, in the cement and then push a flexible camera on a wire inside the cavity. We can adjust to camera and view the inside of the cavity on the borescope.

  • How long does the removal process take?

    For a standard sized family 3 bedroom home the average time required is 2-3 days.

  • What areas do you cover?

    We work and provide cavity wall insulation accross Northern Ireland and greater Belfast.

  • How long is the wait once booked in?
