Beyond a thermal image.

01

Observe

Understand the property and the reported problem.

02

Measure

Record relevant conditions and thermal or moisture indicators.

03

Explain

Distinguish observations from possible causes and further tests.

Illustrative methodology. A thermal image alone is not a definitive diagnosis of water ingress, moisture content or insulation performance.

Building envelope diagnostics & technical advice

A specialist service for every stage of your building problem.

01 / On-site observations

Find out why a room is cold, damp or uncomfortable.

Investigate cold surfaces, condensation conditions and suspected heat-loss or moisture patterns. A site visit can bring together thermal images, relevant environmental readings and observations of the building fabric.

Common reasons to enquire

  • Why is this room colder than the others?
  • Is condensation contributing to recurring mould?
  • Could an insulation or junction issue warrant closer inspection?

On-site thermography and comparative thermal/visual assessment to investigate cold surfaces, condensation conditions and suspected moisture patterns.

Every commission is scoped before work begins. Travel, modelling assumptions, report depth and any additional specialist checks are agreed in advance.

Standards, compliance & technical guidance

Understand the standards behind building investigations.

Practical guidance for homeowners and property professionals. Learn when surveys or calculations may be useful, what evidence they can provide and what they cannot establish on their own.

Do you need a survey, junction calculation or design review?

Tell us about your building concern or the exact project brief. Any specified competence, assessor approval and deliverable will be confirmed before work is agreed. Referencing a standard here is not a claim of certification or accreditation.

Fees & Advice

Our approach

Clear scope. Relevant evidence. Useful reporting.

We agree the question, methods, reporting deliverables and fees before work begins. Findings distinguish observations from possible explanations and identify relevant limitations.

Every investigation is individually scoped and quoted before work begins. Findings are reported with their limitations; thermal images alone cannot establish the cause of a concealed defect.
