Damp & Moisture Problems — Properly Diagnosed
Independent, evidence-led surveys to identify the real cause — not guesswork, not sales-driven solutions.
Often instructed where the cause isn’t clear or previous works have failed.
PCA-trained surveyorsEvidence-led reportingTrusted when answers matter
Clients typically contact us after unclear reports, conflicting advice, or ongoing damp problems.
"We recently experienced a leak that caused significant water damage to our bathroom and flooring, so we contacted Rob for a quote to assess the extent of the damp. From the outset, he was incredibly supportive and professional, taking the time to guide us through every step of the process and clearly explain what needed to be done. His report was both thorough and easy to understand, giving us real confidence in how to move forward. He also made himself available to answer questions at any time, which really helped ease our worries during what has been a very stressful situation. Recommend!"

"I have an older property which has had damp problems since I moved in 8 years ago. I have tried several people but none of them have been as helpful as Rob. Rob responded very quickly and came to do his survey within a few days. He talked me through everything he found and produced a detailed report the next day. Highly recommended."

"The process from start to finish was outstanding it was a pleasure meeting Rob who explained clear defined steps and detailed knowledge surrounding damp issues. The report was equally impressive lots of detailed analysis along with thermal imaging to show the root cause and added remedial actions to undertake to tackle the issues cant recommend highly enough."

"Rob was incredibly thorough and professional while conducting the damp survey on our house. I have just received the report and it is clear that Rob is an expert in his field and has spent a lot of time compiling the report. My son was obsessed with his special ladder and Rob let him climb it and also showed him the thermal images and explained what they meant."

"Rob carried out a specialist damp survey on a property I am looking to purchase, and his input has been invaluable. He was very responsive in arranging the visit, liaising smoothly with the estate agent and keeping me updated at each stage. On site, he explained his findings in clear, straightforward terms, making the technical aspects easy to understand and always steering the conversation towards practical solutions. The report was detailed, solution-focused, and delivered promptly, which has really helped me make an informed decision about the purchase."

Specialist Damp & Moisture Investigations
Examples of how we investigate symptoms, interpret moisture behaviour, identify root causes and guide the correct remedial strategy.

Grade II listed terrace — external moisture, not rising damp
A mid-19th century listed property where previous contractors had proposed chemical damp proofing and internal tanking. The investigation reviewed the age and permeability of the building fabric, the external ground and rainwater context, and the pattern of moisture internally. The evidence pointed to external water management failures and lateral ingress, not rising damp. We recommended a source-first strategy focused on drainage and external detailing rather than internal barriers that could trap moisture and damage the historic fabric.

Escape of water in converted factory flat
Visible floor distortion, fungal growth at the bathroom doorway, and ceiling staining in the property below suggested a wider moisture pathway than surface staining alone. The investigation traced the issue to a concealed leak behind the WC installation within a service void. Moisture had migrated laterally through the floor structure and vertically downwards, explaining the spread of damage and the symptoms in the property below. We provided a staged remedial plan covering leak repair, controlled drying, affected materials and reinstatement.

Listed barn conversion — no active dampness confirmed
A Grade II listed agricultural barn conversion had been flagged for suspected dampness and timber deterioration in a prior RICS Level 3 survey. Our investigation considered the traditional vapour-permeable construction, ventilation context, meter readings and visible fabric condition. The evidence did not support active moisture defects; the readings were consistent with the behaviour of the original construction. We recommended ongoing monitoring and conservation-aligned maintenance rather than unnecessary damp treatment.

Second opinion overturns recommended damp treatment
A homeowner had been quoted for chemical damp proofing and membrane installation by a treatment company. Our independent survey compared the internal moisture pattern with external defects, drainage, junction detailing and rainwater exposure. The findings showed the primary source was external defect and rainwater ingress, not rising damp. By addressing the external drainage and junction detailing, the moisture issue could be resolved without unnecessary internal treatment or disruption.

Repeated mould complaint traced to ventilation failure
A landlord was facing repeated mould complaints after previous contractors had treated the mould cosmetically without identifying the cause. The assessment considered occupancy moisture load, ventilation provision, surface temperature risk, humidity behaviour and visible mould distribution. The evidence showed the issue was driven by inadequate ventilation and excess humidity rather than a primary building defect. We provided a ventilation strategy and monitoring plan so the cause could be controlled instead of repeatedly cleaning the symptom.

Remedial specification for complex basement moisture
A property had complex below-ground moisture issues and multiple contractors had given conflicting advice. The BS 8102-aligned investigation reviewed moisture pathways, below-ground risk, construction interfaces and the limitations of previous recommendations. We separated immediate control measures from longer-term specification decisions and provided a clear, prioritised remedial strategy. The client could then instruct the right specialist works with confidence instead of relying on guesswork.
