    cavity wall insulation removal

    Posted 26 November

    Ben was very communicative and transparent about the mould issue I had. He got the whole job done, removing damp insulation from the walls of my detached house and clearing everything up, in a single day. All for a very reasonable price.

    Competitive service

    Posted 25 November

    Ben King attended and completed the work to a satisfactory standard. He was punctual, polite and explained the process clearly. The extraction itself appears to have been done thoroughly. One challenge we encountered was that several wall cavities were open at the top, which resulted in a large amount of insulation being blown up into the loft space. This has created quite a bit of mess that now needs clearing. I’ll be picking this up with Ben separately. Overall, the service was professional and I’m pleased with the progress, but some follow-up will be required to address the loft clean-up.

    Perfect team for the job!

    Posted 18 September

    The guys did a great job putting some insulation in the loft and removing the boards house nice and warm ready for the winter. The guys were really straight forward, did the job needed and even sent a pic of the loft when the job was done which was a nice added touch. 100% recommend!

    Cavity wall clearance

    Posted 12 September

    Really great result Ben cleared the cavity of my house which had difficult access. Getting to the top of the house was impossible from the outside so he was able to do this from the inside. The job was messy but he took a lot of care to clean up as much as possible. He did a really thorough job and explained the process and any difficulties that came up. His quote was really reasonable - I wouldn't have been able to afford the quotes from the big companies I'd recommend Ben for any work

Why Choose king Cavity Wall Extraction


Over time, cavity wall insulation can break down, become damp, or may have been poorly installed in the first place. When this happens, it stops protecting your home and can actually cause problems such as:


  • Cold spots and draughts – damaged insulation leaves gaps, making your home harder to heat.
  • Damp and mould – trapped moisture in the walls can lead to condensation and structural damage.
  • Higher energy bills – ineffective insulation means you’re paying more to heat your property.
  • Reduced property value – visible damp patches or poor energy performance can put off future buyers


Cavity wall extraction safely removes the failed or unsuitable insulation from your property. Once cleared, the cavities can be left clean and dry, or prepared for new, more effective insulation.

For King’s cavity walls, extraction ensures:

  • A healthier home – no more damp or mould caused by saturated insulation.
  • Better efficiency – your heating system won’t be fighting against blocked or degraded insulation.
  • Futureproofing – once the old insulation is removed, you have the option of installing modern, high-performance insulation.

In short, cavity wall extraction is about restoring your home’s comfort, protecting its structure, and saving you money long-term.
