Liverpool’s historic homes, from Victorian terraces to Georgian townhouses, are full of character and charm. However, these older properties are particularly vulnerable to rising damp, which can cause structural damage, peeling plaster, and mould growth if left untreated.
Understanding how to spot the early signs, identify the causes, and apply the right damp-proofing solutions is essential for preserving Liverpool’s historic homes.
What is Rising Damp?
Rising damp occurs when groundwater travels upwards through porous brickwork, mortar, or stone walls due to capillary action. Older buildings are more susceptible as they were often built without a damp-proof course (DPC) or have a failed or bridged DPC.
Key Causes of Rising Damp in Historic Properties
🔹 No Existing Damp-Proof Course – Many pre-20th-century buildings were constructed without a DPC.
🔹 Bridged Damp-Proof Course – Soil, external render, or internal plaster can create a bridge, allowing moisture to bypass the DPC.
🔹 Porous Masonry – Older brick and stone walls absorb moisture more easily.
🔹 Blocked Subfloor Ventilation – Lack of airflow under suspended timber floors can increase moisture retention.
🔹 High Ground Levels – Patios, driveways, or flower beds built too high against external walls can allow damp to rise.

How to Spot Rising Damp in Older Homes
Look out for these warning signs inside your property:
✅ Tide Marks & Stains – Yellowish-brown stains appearing up to 1m above ground level.
✅ Peeling Paint or Blistering Plaster – Damp weakens finishes, causing bubbling or crumbling.
✅ White Salt Deposits (Efflorescence) – Salts from groundwater appear as white powdery residue on walls.
✅ Musty Odours & Mould Growth – A persistent damp smell is often a giveaway of moisture issues.
✅ Rotting Skirting Boards or Floor Timbers – Rising damp can cause wood decay over time.
