Timber Inspections
At ProCheck Damp & Timber, we carry out thorough and unbiased inspections of structural and joinery timbers to assess for signs of decay, insect attack, and moisture-related deterioration. As independent surveyors, we have no affiliation with treatment contractors — so our advice is based solely on the true condition of your property.

Mould Assessments
At ProCheck Damp & Timber, we conduct independent mould assessments to identify the cause, extent, and risk of mould growth within residential properties. Our focus is not just on identifying the visible mould, but understanding why it’s occurring, and how to prevent it — without any conflict of interest.
We are qualified, impartial surveyors, with no links to cleaning or treatment companies. This means our advice is honest, practical, and based on evidence, not sales.
