Services
Cavity Wall Insulation Removal
Specialist removal of failed cavity wall insulation using advanced extraction techniques. We address damp, cold spots, and structural issues caused by defective insulation. Our ISO-certified process restores property integrity while meeting lender requirements for mortgage eligibility.
Thermal Imaging Surveys
Non-invasive thermal diagnostics to identify insulation failures, moisture ingress, and structural defects. Our RTK-geolocated imaging provides precise data for remediation planning, ensuring energy efficiency and compliance with building regulations across residential and commercial properties.
Spray Foam Removal
Professional removal of problematic roof spray foam insulation. We restore roof structures to surveyor-accessible condition, providing documentation for mortgage approvals. Our CHAS-accredited team ensures safe, dust-controlled operations with full waste management compliance.
Remedial Wall Ties
Replacement of corroded wall ties with stainless steel and neoprene alternatives. This structural repair prevents brickwork cracking and moisture ingress, using PAM Ties-manufactured components that meet British Standards for masonry stability and longevity.
Flood Damage Restoration
Comprehensive flood damage recovery including cavity wall decontamination and structural drying. We employ thermal imaging and boroscope inspections to identify hidden moisture sources, removing wet insulation materials within 48 hours to prevent long-term property damage.

Questions
What causes cavity wall insulation problems?
Failed installations create cold spots and damp through 40% of UK properties. Moisture reduces insulation effectiveness by 1% or more, increasing energy costs and causing structural damage through condensation and mould growth.
How does thermal imaging help property inspections?
Thermal imaging detects temperature variations indicating insulation failures, moisture ingress, and structural defects. Our RTK-geolocated diagnostics provide verifiable data for remediation planning and building regulation compliance across residential and commercial properties.
Why remove spray foam from roofs?
Spray foam prevents roof inspections and traps moisture, causing timber decay. Lenders require removal for mortgage approvals. Our TrustMark-certified process restores roof structures to surveyor-accessible condition while maintaining structural integrity during extraction.
What areas do you service?
We operate across the North West, covering Lancashire, Cumbria, Fylde Coast, Greater Manchester, Merseyside, and Cheshire. Emergency flood response services extend nationwide through our network of accredited contractors.
How long does insulation removal take?
Standard cavity wall insulation removal for a 3-4 bedroom property takes 48 hours. Spray foam removal requires 4-7 days depending on roof complexity, with full re-roofing projects extending to 10-14 days when necessary.
