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 moisture-related. Our pre-purchase survey focuses on damp and mould—pinpointing the true cause and the scale of risk before you commit.

Why choose an independent damp survey?

  • No sales agenda: we don’t sell remedial works or products—just impartial, evidence-based advice.

  • 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.

  • Avoid unnecessary works: we distinguish between condensation, penetrating damp, plumbing leaks, ventilation/insulation issues and timber risks—so you fix the right thing.

What we check

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

  • Ventilation performance, extract fans and airflow paths

  • Insulation & thermal bridging (cold spots)

  • Rainwater goods & flashings likely to cause ingress

  • Timber condition (risk indicators for decay/woodworm)

  • Occupancy/behavioural factors that may be contributing

How we test

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

What you’ll receive

  • Independent PDF report in 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)

  • Guidance you can pass to your contractor or include in solicitor enquiries

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 need 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.
