Professional Insulation Damp Survey
Expert damp and moisture surveys specifically for insulation-related problems. Get definitive answers about whether your damp is caused by failed insulation - with professional evidence for compensation claims.
Why You Need a Professional Damp Survey
Prove Causation
A professional survey provides scientific evidence that your damp problem is caused by the insulation installation - not pre-existing issues. This is critical for compensation claims and disputes with installers who claim the damp was already there.
Secure Compensation
Without a professional survey, compensation claims are easily rejected. CIGA, Trustmark, and energy companies require independent surveyor reports as proof. This survey gives you the evidence you need to claim £5,000-£35,000+ in compensation.
Mortgage Requirements
Lenders increasingly require damp surveys before approving mortgages, especially if spray foam or cavity wall insulation is present. This survey satisfies mortgage requirements and can identify if removal is necessary for your sale to proceed.
Avoid Costly Mistakes
DIY diagnosis often leads to expensive, unnecessary treatments. A professional survey identifies the root cause, saving you thousands on ineffective damp treatments that don't address the real problem - the insulation.
What's Included in Your Survey
Moisture Meter Testing
Professional-grade capacitance and resistance moisture meters measure moisture levels throughout your property. We record readings in:
- • All external walls (inside and out where possible)
- • Areas with visible damp or mould
- • Control areas (non-affected walls for comparison)
- • Timbers in roof space if spray foam is present
- • Behind radiators and furniture where practical
Thermal Imaging Survey
Infrared thermal imaging cameras detect temperature differences that reveal:
- • Cold spots indicating insulation gaps or failures
- • Moisture presence (appears as cold patches)
- • Air leakage paths causing condensation
- • Thermal bridging through wall ties or fixings
- • Uninsulated areas vs insulated areas
Visual Inspection & Diagnosis
Comprehensive inspection by RICS-certified surveyor covering:
- • Mould growth patterns and locations
- • Condensation on windows and walls
- • Ventilation adequacy (trickle vents, extractor fans)
- • External wall condition and render/cladding defects
- • Roof space inspection (ventilation, timber condition)
- • Signs of penetrating damp vs condensation
Detailed Written Report
Professional report delivered within 48 hours including:
- • Executive summary of findings
- • All moisture meter readings with locations marked on plans
- • Thermal imaging photographs with analysis
- • Photographs of all affected areas
- • Professional opinion on cause of damp (with references to building standards)
- • Link between insulation installation and damp problems
- • Recommendations for remediation
- • Cost estimates for necessary work
- • Guidance on compensation claims
Insulation-Related Damp Problems We Identify
Condensation Damp
Most common with cavity wall and spray foam insulation. Blocked ventilation causes moisture to condense on cold surfaces.
Interstitial Condensation
Hidden condensation within wall cavities or behind insulation. Common with external wall insulation without vapor control layer.
Penetrating Damp
External wall insulation can trap water in walls or cause new water ingress points through poorly installed fixings and renders.
Timber Rot & Decay
Spray foam blocks roof ventilation, trapping moisture in timbers. Leads to wet rot, dry rot, and structural damage.
Cold Bridging
Incorrectly installed insulation creates cold spots where moisture condenses. Common with internal wall insulation at junctions.
Wall Cavity Saturation
Cavity wall insulation absorbs water from rain penetration or condensation, creating a permanent damp reservoir in your walls.
