Independent Damp & Moisture Assessment
We identify the cause of damp, mould and moisture issues using evidence-led investigation — giving you clear conclusions and practical next steps you can rely on.
Independent
Not tied to products or treatments
Evidence-led
Moisture profiling, thermal imaging and building analysis
Specialist cases
Often instructed after failed or unclear previous advice
Clear outcomes
Diagnosis, explanation and practical next steps
Services built around real decisions
We structure our services around the decisions clients actually need to make — understanding the cause, confirming the extent, and knowing what to do next.
Moisture, Damp & Mould Assessment
Used where damp, mould or condensation is present and the cause is unclear.
We assess moisture behaviour, identify the source, and explain what is actually happening — not just the symptoms.
Includes
- Moisture profiling and pattern interpretation
- Thermal imaging and condensation analysis
- Ventilation and humidity assessment
- Mould cause identification
Where relevant, assessment considers principles aligned with BS 6576 for ground-related moisture behaviour.
Condensation & Ventilation Assessment
Used where mould or condensation is recurring or linked to internal conditions.
We assess humidity, airflow, and cold surface risk to identify the root cause.
Includes
- Humidity behaviour and dew point risk
- Ventilation performance and airflow review
- Thermal bridging and cold surface identification
- Prevention-focused recommendations
Assessments are informed by BS 5250 principles for condensation and moisture control.
Leak Investigation & Water Ingress
Used where water ingress is suspected from plumbing, roofing or external defects.
We identify the source and clearly distinguish between cause and resulting damage.
Includes
- Leak tracing and moisture spread assessment
- Cause vs damage differentiation for insurance and remedial planning
- CCTV drainage surveys where required to confirm defects and water pathways
- Targeted investigation where required
Reporting is structured to support insurance claims and, where applicable, insured remedial or project works support by clearly defining cause, extent and required action.
External & Waterproofing Assessment
Used where water ingress is linked to external construction, ground levels or waterproofing systems.
Includes terraces, façades, balconies and below-ground structures.
Includes
- External envelope assessment
- Deck, podium and waterproofing review
- Drainage interface and discharge analysis
- Water tracking and ingress pathways
Assessments are aligned with BS 8102 guidance for below-ground and structural waterproofing.
Heritage Building Assessment & Planning Support
Used for older or traditionally constructed buildings where modern damp treatments are often inappropriate.
We assess moisture behaviour and provide guidance suitable for conservation and planning.
Includes
- Solid wall moisture behaviour
- Breathability and material compatibility
- Conservation-aware recommendations
- Planning and design support
Complex Investigations & Intrusive Assessment
Used where the cause of moisture cannot be confirmed through non-invasive inspection alone.
We carry out targeted investigation to verify construction and identify hidden defects.
Includes
- Borescope inspection of concealed areas
- Selective opening-up where required
- CCTV and other investigative methods where necessary
- Hidden defect identification
- Verification of moisture pathways
Reporting is structured to support insurance claims and, where applicable, insured remedial or project works support by clearly defining cause, extent and required action.
Complex Cases & Second Opinions
Used where previous reports or treatments have not resolved the issue.
We provide an independent review to identify misdiagnosis and establish the correct approach.
Includes
- Review of prior surveys and works
- Identification of incorrect assumptions
- Clear, evidence-based conclusions
- Practical next-step strategy
Often instructed where insurance claims have been disputed or where previous reports have lacked clarity.
Pre-Purchase Risk Assessments
Used by buyers who need clarity before committing.
We identify risks, likely costs, and whether issues are manageable.
Includes
- Damp risk identification
- Severity and implications explained
- Guidance for negotiation or works
- Clear, decision-focused reporting
Commercial & Compliance Assessments
Used for landlords, agents and commercial buildings requiring structured reporting.
Aligned with compliance requirements and risk management.
Includes
- Damp and mould compliance reporting
- Multi-occupancy and HMO considerations
- Environmental and moisture assessments
- Clear, structured outputs
Reporting suitable for housing providers, insurers and regulatory requirements.
Damp & Mould Assessment
Moisture profiling, thermal imaging, mould and salt testing with evidence-led conclusions on cause and extent.
Specialist Damp & Moisture Investigations
Consultancy-led investigation for unclear moisture behaviour, defect pathways, thermal patterns and failed previous repairs.
Condensation & Ventilation Assessment
Assessment of humidity, airflow, thermal bridging, and mould risk in condensation-led cases.
Basement & Below-Ground Waterproofing Assessment
Below-ground and basement assessment with moisture-risk analysis and waterproofing guidance.
Leak, Drainage & External Defect Investigation
Selective invasive work and CCTV drainage surveys to confirm hidden ingress with photo and video evidence.
Remedial Specifications & Project Support
Diagnosis-led remedial scopes, contractor guidance, and next-step project support.
How we work
Understand. Test. Explain. Advise.
Step 1
Context & Brief
We start by understanding the issue, the building, and what decision you need to make.
Step 2
Investigation & Testing
We assess moisture behaviour using observation, measurement and building science — not assumptions.
Step 3
Reporting & Advice
You receive a clear explanation of the cause and practical next steps you can act on with confidence.
Need a clear answer, not a guess or a generic quote?
We provide proper diagnosis so you can understand what’s happening and what should be done — rather than jumping straight into unnecessary works.
Remedial Works — Where Required
Our primary role is to diagnose the cause of moisture issues and define the correct solution.
Where remedial works are required, we can support or undertake their implementation — ensuring everything is aligned with the original diagnosis.
This includes both internal and external works, delivered in a controlled and proportionate way.
Includes
- Internal damp remediation and reinstatement
- External repairs and water ingress works
- Structural and waterproofing interventions
- Coordination with contractors and specialists
All works are based on evidence-led findings — not pre-defined systems or assumptions.
Built for Clarity
Every client needs clarity, not guesswork.
We don’t offer quick fixes or push treatments. Our role is to understand what’s happening, explain it clearly, and help you make the right decision.
Each assessment is based on independent methodology, measurable data, and professional judgement — giving you conclusions you can rely on.
Standards-informed approach
Our assessments are informed by recognised industry standards including BS 5250 (control of condensation), BS 8102 (below-ground waterproofing), and BS 6576 (rising damp), alongside practical building investigation principles.
This ensures our recommendations are technically grounded, proportionate, and appropriate to the building.
Reporting That Stands Up
Our reports are structured to clearly define cause, extent and required action — not just describe visible symptoms.
This makes them suitable for use in insurance claims, disputes, and decision-making by landlords, agents and project teams.
Trusted when answers matter
Clients come to us when they need clarity — often after unclear or conflicting advice.
