Key factors contributing to damp problem:

  • Rising Damp: This is mainly caused when the existing Damp Proof Course (DPC) breaks
    down or becomes bridged.
  • Penetrating Damp: This is when rainwater starts to enter the internal fabric of the
    property.
  • Salt Damp: This is
    when plaster becomes contaminated with salts.
  • Condensation Damp: This is mainly caused by poor heating and a
    lack of adequate ventilation and insulation.
  • Coastal proximity: The close
    proximity to the sea increases humidity levels in the air, readily depositing
    moisture on surfaces when temperatures drop. 
  • Older buildings: Many older
    Victorian properties in Portsmouth may have inadequate insulation and
    ventilation systems, making them more prone to condensation. 
  • Poor heating practices:
    Insufficient heating or inconsistent temperature control in homes can worsen
    condensation issues. 
  • Lifestyle habits: Activities
    like cooking, showering, and drying clothes indoors generate moisture, which
    can contribute to condensation if not properly ventilated. 

What can be done to manage damp in Portsmouth? See our Condensation survey.

  • Improve ventilation: Regularly
    open windows to allow air circulation and prevent moisture buildup. 
  • Adequate heating: Maintain
    consistent heating levels throughout the home to minimize temperature
    fluctuations. 
  • Insulation upgrades: Consider
    adding insulation to walls and lofts to improve energy efficiency and reduce
    heat loss. 
  • Addressing leaks: Promptly
    repair any leaks or water damage to prevent further moisture ingress. 
  • Dehumidifiers: Using
    dehumidifiers can help remove excess moisture from the air.
