Building Performance Diagnostics
Investigation, testing and diagnostic services that identify heat loss, condensation, moisture, air leakage, thermal bridges and indoor environmental issues — before any remedial works are specified.
What building performance diagnostics covers
Most building problems are misdiagnosed. A damp patch is treated as a leak when it is really condensation; a cold room is re-insulated when the real issue is air leakage or a thermal bridge. Guessing wastes money and often makes things worse.
Our diagnostics stage uses calibrated instruments and recognised building-physics methods to measure what is actually happening in your building. Only once the cause is proven do we move to design — so every pound you spend is targeted at the real problem.
Diagnose before you spend. Measured evidence turns a guess into an engineering decision and protects your investment.
Investigate → Design → Verify
Our three service categories form one connected engineering journey. Each stage builds on measured evidence from the last.
