Need to know before you purchase?

Buying a home is stressful enough without surprise moisture problems. While most buyers commission a general condition survey, the issues that most often cause hidden damage, health concerns and unexpected costs are damp and mould. Our pre-purchase survey focuses on these risks — pinpointing the true cause and the scale of risk before you commit.

Why choose ProCheck?

  • No sales agenda – impartial, evidence-based advice focused on accurate diagnosis first.

  • Negotiation power – photos, readings and a prioritised action plan help you negotiate fairly.

  • Clarity fast – every report is delivered within 1 working day, so you can keep your purchase moving.

  • Targeted solutions – we distinguish between condensation, penetrating damp, plumbing leaks, ventilation/insulation issues, and timber risks — and where works are required, we can ensure they’re carried out properly.

What we check

    • Signs and sources of condensation, penetrating damp, plumbing leaks

    • Ventilation performance, including extract fans and airflow paths

    • Insulation & thermal bridging (cold spots)

    • Rainwater goods & flashings that may allow ingress

    • Timber condition (decay/woodworm indicators)

    • Occupancy/behavioural factors that may be contributing

    How we test

    Professional instruments only — no guesswork. We use protimeters, hygrometers, and thermal imaging (where appropriate), alongside visual inspection and moisture profiling, to map the issue accurately.

    What you’ll receive

    • PDF report within 1 working day

    • Plain-English findings with photos/thermals where relevant

    • Moisture readings and a root-cause summary

    • Clear, practical recommendations (prioritised: Urgent / Essential / Desirable)

    • Option for remedial works if required, ensuring problems are fully resolved

    How it works

    1. Book a survey (short-notice slots available across Hertfordshire, London & nearby).

    2. On-site assessment with instruments and targeted testing.

    3. Report within 1 working day — plus a follow-up call if you’d like to talk it through.

    When it’s worth doing

    • A general survey has flagged possible damp/mould.

    • You’ve noticed staining, musty odours, or cold/black-spotted corners.

    • The property is older, recently refurbished, or shows altered ventilation.

    • You want evidence to support price discussions or conditions of sale.
