Cavity Wall Extraction

Can Cavity Wall Insulation Be Removed?

Whenever we hear a question about cavity wall insulation removal, we know that someone is in trouble. Cavity wall insulation has so many fantastic benefits, but if it hasn’t been fitted properly by a qualified team of installers, then things can go wrong. This is especially true with older installations.

Luckily though, the answer to the question is yes, cavity wall insulation can be removed.  Similarly to the installation of insulation, cavity wall extraction requires specialist equipment and should only be carried out by an experienced team of installers. For more information regarding getting your cavity wall insulation removed or assessed, please give us a call on 0800 1583605 or press “Get In Touch” and send us a quick message.

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.

Cavity Wall Insulation Removal process

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.  

The following materials can be extracted from cavity walls.

  • Expanded Polystyrene
  • Loose or bonded Urea Formaldehyde Insulation
  • Rockwood Mineral Fibre
  • Whitewool Glass Mineral Fibre

This is an incredibly safe procedure, which will cause no disturbance to the fabric of your building. Our extraction team take great pride in leaving your property in pristine condition. As such, they will take away all waste ensuring that nothing is left behind.

How long does it take to remove cavity wall insulation?
