  • Diagnosis from a cheap moisture meter only
  • Chemical DPC sold without checking gutters, ground levels or leaks
  • Pressure to sign today

Insist on

  • One written fixed price for the full scope — no open-ended hours.
  • Deposit of 10–20% at most; balance after you inspect the work.
  • Any extra work agreed and priced in writing before it starts.
  • Most 'rising damp' is actually condensation or a leak. Fix gutters, pointing and ventilation first.
  • Insist on an independent survey (PCA / surveyor), not one by the seller of the treatment.
