10 Top Tips for dealing with damp in a heritage home

  1. Do not rush into remedial action – treat the causes, not the symptoms.
  2. Avoid expensive, intrusive and potentially damaging work until you have consulted with an expert. Take qualified advice.
  3. Avoid ineffective and potentially damaging industry solutions such as injected damp proof courses (DPCs).
  4. Remove cracked cement render and refinish external walls using breathable lime-based renders.
  5. Check for damaged pointing and re-point using soft lime mortar.
  6. Repair or renew gutters and downpipes and ensure that water is channelled away from the house to a soakaway or drain.
  7. Replace modern concrete floors with a breathable alternative.
  8. Improve ventilation, especially in kitchens and bathrooms.
  9. Insulate the home using only natural, hygroscopic materials, such as sheepswool, wood fibre or hemp.
  10. Strip modern internal finishes and replace with lime-based plaster products such as Breathaplasta. Lime plaster has an attractive natural finish. If painting, ensure that a natural, breathable paint is used.
