Cavity wall extraction is exactly what it says on the tin. It is the process of extracting and removing the insulation from inside the cavities of your external wall. Using a method of pumping compressed air to push the insulation to the bottom and using a specialist vacuum to collect all of the fallen material.
Cavity wall extraction requires specialist equipment and knowledge to remove the unwanted insulation from inside your walls successfully.

Cavity wall insulation is a great way to save money on your energy bills, prevent heat from escaping through your walls and keep your home warmer in winter and cooler in the summer.

The government has recommended cavity wall insulation as a primary measure in Government energy efficiency initiatives, including the Energy Company Obligation, designed to provide low-cost and free insulation to eligible and qualifying households, helping to reduce carbon emissions and tackle fuel poverty.

When the cavity wall insulation is defective, homeowners should remove and replace it.

Suppose you are experiencing problems with existing insulation installed without an appropriate industry-backed guarantee. In that case, the good news is that we can assess your insulation and property suitability and customise the best solution for your home.

There may be several reasons why you may need your cavity wall insulation replaced:

  • Insulation produces cold or damp spots within the building fabric if incorrectly installed.
  • Defective insulation
  • Insulation becoming wet through poorly maintained properties
  • Insulation becomes wet through flooding or fire damage.
  • Leaking roof

Should the existing cavity insulation be removed?

There are a couple of ways of finding out if there are any problems with your insulation. It can be as simple as looking around the property for poorly maintained brickwork or insulation patches exposed to the elements (possibly via the roof). Using a borescope inspection is a relatively quick and easy way to determine the type of insulation used and how it’s performing and gather photographic evidence from around the property to understand where any problems may be occurring.

Our team will be happy to asses this for you.

Thermal imaging is another tool that helps diagnose areas of the property that may be losing heat and provides a map of where cavity insulation may fail.
