Frequently Asked Questions

Our team is just a click away if you need any advice about removing faulty cavity wall insulation, but here are some answers to the questions our customers ask most.

  • What is the BBA?
    We are fully accredited by the BBA, which is ithe international authority on approved products in the construction industry. This means that the products we use, our installers and systems are inspected and accredited by the BBA, ensuring you can rely on us to use best practice in your home.
  • How is cavity wall insulation removed?
    We drill a series of holes in the mortar line and use air pressure to force the insulation materials down to the extractor. Once the extraction is complete and the cavities are clear, after a thorough investigation, we return your home to its original state.
  • Why does my cavity wall insulation need to be removed?
    Some properties aren’t suitable for cavity wall insulation or if the insulation wasn’t installed properly, damp patches may start to form. It may be that leaking pipes or porous brickwork has allowed water to enter the cavity, causing damp to develop. We can carry out a full assessment and talk you through the next steps to restore your home to its prior condition.
  • How will I know that all the faulty insulation has been removed?
    Once we have removed all the insulation from your cavity walls, we do a complete inspection using cameras. This allows us to see into the cavity and we can provide you with images, so you can see for yourself. And because we are BBA accredited you get the added peace of mind that we are following best practice.
