Why extract insulation from your cavity walls?

Here at Westville, we are always keen to endorse the fantastic benefits of cavity wall insulation, so you may ask the question, “why would I want to remove my insulation?” The truth is, as fantastic as modern day cavity wall insulation is, older installations, with inferior products, have the potential to go awry, with many of them now outside of the 25 year guarantee period. It is for this reason that we now offer a cavity wall insulation removal service.

As mentioned above, old insulations were quite different to the modern day versions available today. Different materials were used which were not subject to the same level of regulation and certification as our modern equivalents of today. As a result, these older materials can be vulnerable to a set of very rare but rather serious issues. Below are some of the most common reasons why people require cavity wall extraction.

  • Old, defective insulation which has broken down and begun to release toxic gases.
  • Insulation material that has become wet due to severe flooding or burst pipes and has therefore broken down.
  • Badly installed cavity wall insulation which is not working efficiently.

The removal process starts with Westville visiting your home with specialised equipment that resembles an industrial vacuum. This equipment is initially inserted into a small hole at the base of your properties external wall, to effectively extract all of the defective material. This process is repeated all the way up your property until the entire cavity is empty.
