A lot of damp and mould confusion comes from relying on one number, usually “humidity”.

On inspections I use a Protimeter MMS3 because it lets me record conditions properly, including:
• relative humidity (RH)
• specific humidity (g/kg), useful for comparing moisture load between spaces
• surface temperature checks (condensation risk)
• moisture measurement to support what we’re seeing on site

Why it matters: a room can show high RH simply because it’s cold. Comparing moisture load (g/kg) and checking surface temperatures helps separate condensation risk from true moisture sources.

Thermal imaging is one of the quickest ways to move from it feels damp to heres where we should investigate.

I use a FLIR E76 thermal imaging camera to identify surface temperature patterns that can be linked to:
 cold bridging (often behind mould at corners and window reveals)
 air leakage paths
 insulation defects
 areas that may be influenced by moisture

Important point: thermal imaging doesnt see damp on its own. It shows temperature differences. I always confirm findings with moisture measurement and contextual readings.

Not sure whether it’s condensation, a leak or penetrating damp? A proper diagnosis shouldn’t be guesswork.

On a typical damp/timber/building inspection I use a small toolkit of methods (not just one reading) so the conclusions are evidence-led and defensible.

That usually means combining thermal imaging, moisture measurement and hygrometry, roof-level inspection (often by drone), and (where needed) ventilation airflow testing.

I’ve written a short guide explaining what each tool can (and can’t) prove here:

If you’re in North West England (LA, FY, PR, BB, BL) and want an independent diagnosis, message me your postcode and a couple of photos.

Quick damp/mould myth-buster:

A moisture meter reading on its own does not tell you the cause.

That is why I use a mix of:

- Thermal imaging (pattern and context)
- Hygrometry (RH and moisture load)
- Surface temperature checks (condensation risk)
- Targeted moisture readings (pinless and pin, where appropriate)

It is the combination that stops you paying for the wrong fix.

If you are in LA, CA, FY, PR, BB or BL and want an independent report you can actually trust (no remediation sales), book via https://www.fullst.co.uk or message me.

Thermal imaging is brilliant, but it is not magic.

What it does really well is show temperature patterns that point you towards the cause of a problem.

A few examples:

- Cold vertical streaks can suggest missing insulation or thermal bridging.
- Cold patches that change after rainfall can suggest moisture ingress.
- A cold halo around a chimney breast can be a clue (but it still needs checking).

Then we confirm with proper moisture readings and a sensible inspection, so you are not paying for guesswork.

Thermal imaging is not magic.

But used properly, it is a brilliant way to see patterns that help you diagnose damp, leaks and heat loss without ripping your house apart.

What it can do well:
- Highlight cold spots and moisture patterns
- Help trace leaks and missing insulation
- Show where to investigate next (with moisture readings to confirm)

What it cannot do:
- Prove damp on its own
- Replace proper inspection and measurement

If you are getting conflicting advice (or you have been sold a quick fix that did not fix anything), message me or call and we will talk it through.
