Failed or damp cavity wall insulation needs to be removed and replaced. As a CIGA-registered cavity wall insulation removal company, we extract old insulation and refill your walls across London, Essex, Kent, Surrey and Hertfordshire.
Cavity wall extraction involves removing insulation material from the cavities within your external walls. This process is essential when the existing insulation has degraded, become damp, or is no longer effective.
Successful cavity wall extraction demands expert knowledge and specialised equipment.
Professionals trained in this service can effectively identify and address insulation problems, ensuring the integrity and efficiency of your home’s insulation system. Whether for maintenance, repairs, or upgrading to a more efficient insulation solution, cavity wall extraction is a crucial service for maintaining a comfortable and energy-efficient home.
Once the old material is removed, we can refill the cavity with modern EPS bead insulation, backed by a 25-year CIGA guarantee.
Old or poorly installed insulation can trap moisture within your walls, leading to dampness and mould growth. Removing the compromised insulation helps maintain a dry and healthy living environment, preventing structural damage and health issues.
Over time, insulation can settle or degrade, reducing its effectiveness. Extracting and replacing old insulation enhances your home's thermal efficiency, resulting in lower energy bills and a more comfortable indoor climate.
Retained moisture within cavity walls can weaken the structural integrity of your home. By removing ineffective insulation, you prevent potential damage to the walls and foundation, ensuring the longevity and stability of your property.
Advances in insulation technology mean newer materials offer better performance. Investing in cavity wall extraction allows you to upgrade to modern, more efficient insulation, improving your home's overall energy performance and value.
Complete the entire project in approximately two days for an average 3-bedroom detached property.
Insert a compressed air line into the cavity wall.
Attach a flexible suction vacuum by removing a single brick below the air line to collect the fallen insulation.
Use the air line to push compressed air into the wall, breaking up the insulation and directing it towards the suction nozzle.
Safely extract the damaged insulation material from the cavity.
Remove the vacuum and air line & restore any holes and gaps in the wall.

The cost of cavity wall insulation removal varies depending on the size and complexity of the job. On average, homeowners can expect to pay between £1,500 and £3,000.
Cavity wall insulation is removed by inserting a compressed air line into the cavity wall to dislodge the insulation and then using a specialised vacuum to extract the material safely.
While it is technically possible to remove cavity wall insulation yourself, it is highly recommended to hire professionals due to the specialised equipment and expertise required for safe and effective removal.
A cavity wall should ideally be insulated with EPS (Expanded Polystyrene) beads. EPS beads provide excellent thermal performance, are resistant to moisture, and offer long-term durability. However, there are other insulation materials that can be used for cavity wall insulation.
Grants for removal are rarely available. However, if your original insulation was installed with a CIGA guarantee and has failed because of a defect, the guarantee may cover the cost of putting it right. We can check this for you during your survey.
The entire process typically takes around two days for an average 3-bedroom detached property, though this can vary depending on the specific circumstances.
Removing old or damaged insulation can prevent issues like dampness and mould, improve energy efficiency, and protect the structural integrity of your home.
When performed by professionals, cavity wall extraction is done carefully to minimise any damage. Any necessary holes or gaps created during the process are restored afterwards.
Signs that your insulation may need removal include damp patches on walls, mould growth, increased energy bills, or noticeable drafts.
After removal, the cavities can be refilled with modern, efficient insulation materials such as EPS beads, ensuring improved thermal performance and comfort in your home.
