Extraction of Failed or Old Cavity Wall Insulation

Do you have dampness, mould, or cold patches? It may be due to poorly installed or deteriorating cavity wall insulation. At Zest, we specialise in diagnosing and safely extracting failed insulation using advanced vacuum and cleaning systems. This process removes moisture-retaining debris and contaminants from your walls, restoring your home’s breathability and structural health.

Our whole-house approach under the PAS 2035 framework ensures that insulation removal and reinstatement are handled with precision. We don’t just fix the issue—we address its cause. Following extraction, we can specify and reinstall the right insulation system for your property, giving you lasting protection and renewed comfort.

Poor installation or unsuitable materials can cause trapped moisture and cold spots—leading to damp, mould, and structural damage. Zest’s integrated PAS 2035 approach assesses your entire building fabric, ensuring that ventilation, insulation, and waterproofing all work together seamlessly. We provide holistic solutions that restore warmth, comfort, and peace of mind for the long term.
