Cavity Wall Extraction & Installation Service

Modern Cavity Wall Insulation is an effective way to increase the energy efficiency of your home. We remove defective insulation and provide 25 year insurance backed guarantee for EPS Bead installs.

Cavity Wall Insulation Delivered — or Corrected — the Right Way

Cavity wall insulation can deliver significant energy efficiency benefits when designed and installed correctly. However, historic installations, changing standards, and unsuitable property conditions have left many homes with underperforming or failed cavity insulation.

We provide specialist cavity wall extraction and installation services as part of a whole-house insulation approach, ensuring cavity insulation supports building performance rather than causing damp, heat loss, or compliance issues.

Assessment First, Installation Second

Cavity wall insulation should never be treated as a one-size-fits-all measure. Our approach prioritises diagnosis, suitability, and system compatibility before any installation or remediation takes place.

Our process includes:

  • Property & Cavity Assessment
    We assess wall construction, exposure, moisture risk, existing insulation condition, and suitability against current standards.

  • Extraction Where Required
    Where insulation is degraded, non-compliant, or unsuitable, we safely extract existing material to prevent ongoing performance or moisture issues.

  • Correct Specification & Installation
    Where appropriate, new cavity insulation is specified and installed using compliant methods and materials suited to the property type and environment.

  • Integration With Whole-House Retrofit
    Cavity insulation is designed alongside ventilation, heating, and other fabric measures to ensure balanced performance.

Who This Service Is For
  • Homeowners experiencing issues with cavity insulation

  • Landlords and portfolio owners

  • Social housing providers and councils

  • ECO, GBIS, and remedial retrofit programmes

  • Properties affected by historic or failed cavity insulation

What we address

Let us see how we can help you.

Failed or Degraded Cavity Wall Insulation

Older or poorly installed insulation can slump, absorb moisture, or create cold spots. We assess and remove material where performance is compromised.

Damp, Condensation & Moisture Risk

Incorrect cavity insulation can contribute to damp and condensation. We identify moisture pathways and address root causes before reinstallation.

25 Year Insurance Backed Guarantee

All our works are manufacturer and labour guaranteed for 25 years including brick and render finishes.

Key Benefits

No. Suitability depends on construction type, exposure, cavity condition, and moisture risk. We assess each property individually before recommending installation.
Cavity insulation may need removal where it is degraded, incorrectly installed, causing damp issues, or no longer compliant with current standards.
Yes. Cavity wall insulation performs best when delivered as part of a coordinated, whole-house retrofit that considers ventilation and heating.
We plan works carefully to minimise disruption, particularly in occupied homes, and communicate clearly throughout the process.
