Moisture Meter Leak Detection
in London

Our engineers take calibrated moisture readings at regular intervals across the affected area and the surrounding structure. Each reading records the moisture content of the material at that point. By mapping how readings increase and decrease across the area, we identify the direction moisture is travelling and locate the point of highest saturation. That peak is where the source is. The full grid of readings is included in our written report so the pattern is visible and auditable.

In most cases, no. Pinless moisture meters scan through surfaces without any contact damage. Where pin-type readings are needed, the probes leave marks smaller than a pin point in the surface. No tiles are lifted, no walls are opened and no floors are disturbed during the survey itself. If the survey confirms a leak that requires repair access, the engineer discusses the exact location with you and agrees the cost before any physical work begins.

No. 0800 Homefix does not charge a call-out fee. You pay for the first hour of labour, which covers the engineer’s arrival, the full moisture survey, diagnosis and the job itself. If the investigation or repair requires additional time beyond the first hour, we provide a fixed price quote before proceeding. Evening, weekend and bank holiday visits carry a small out-of-hours uplift, confirmed when you call. Full details are on our rates page.

Moisture mapping is most accurate when a systematic grid approach is used rather than spot readings. On a typical residential job, our engineers take readings at 200 to 300mm intervals across the affected area, which gives enough data points to see the gradient clearly. On timber and plasterboard surfaces, this approach is typically accurate to within 150mm of the source. On dense masonry the accuracy reduces slightly, which is why we combine moisture mapping with thermal imaging on complex solid-wall jobs.

A single affected area in a residential property typically takes between one and two hours including the moisture survey, follow-up confirmation and discussion of findings. Larger properties or surveys covering multiple rooms take longer. When you call 0800 Homefix, we will give you a realistic time estimate based on what you describe before the engineer is despatched.

Yes. Every 0800 Homefix moisture meter survey includes a written report with the full grid of readings, the identified moisture boundary, our interpretation of the data and our conclusion about the source. This report meets the format requirements of the major UK insurers for water damage and trace and access claims. Reports are delivered within 48 hours of the survey as standard. If you have a claim reference number, call us with it and we can often arrange a same-day visit.

Moisture mapping identifies where moisture is present and establishes the direction of travel. In many cases this is sufficient to confirm the source. For leaks in pressurised systems where moisture levels are elevated but no single peak is clear, we combine moisture mapping with thermal imaging or acoustic detection to confirm the exact failure point before recommending any access. We decide on the appropriate combination when we arrive and assess the specific conditions.

Yes, in most cases. Our engineers carry out both the investigation and the repair in the same visit where possible. Once the moisture survey and any follow-up detection have confirmed the source, a fixed price for the repair is agreed with you before any access work starts. After the repair, we carry out a follow-up moisture reading to confirm levels are returning to normal before we leave. One call, one visit, one invoice.
