Treating Damp in Internal Walls and Cellar in Accrington

We’ve noticed signs of damp on the internal walls near the staircase and in the cellar of our property in Oswaldtwistle, Accrington. We’d like a professional inspection and recommendations on how to treat the existing damp and prevent further issues.

Understanding the Causes of Damp

Damp in internal walls and cellars is a common issue in older properties, particularly in areas like Accrington, where many homes were built before modern damp-proofing technologies. Typical causes include rising damp, penetrating damp, and condensation, all of which require different treatment approaches.

Steps for Professional Damp Inspection

1. Identifying the Source

A professional survey will locate the source of the damp. Signs such as watermarks, flaking paint, and musty odours can help identify whether the damp is caused by groundwater (rising damp), leaks (penetrating damp), or poor ventilation (condensation).

2. Assessing the Extent

Using tools like moisture meters, contractors measure the affected areas to determine the damp’s severity. In cellars, additional checks for structural damage or compromised waterproofing are performed.

3. Preparing a Treatment Plan

The inspection results guide the choice of treatments, ensuring a tailored approach that addresses the root cause and prevents recurrence.

Treatment Options for Damp

1. Rising Damp

If groundwater is seeping into the walls, a damp-proof course (DPC) may be installed. This involves injecting a chemical barrier into the walls to stop moisture from rising. Skirting boards and plaster are replaced to remove contaminated materials.

2. Penetrating Damp

For water entering through cracks or porous masonry, repairs to external walls, guttering, or roofing are essential. Waterproof coatings or sealants may also be applied to create an additional barrier.

3. Condensation

Improving ventilation is key to tackling condensation. Installing extractor fans, dehumidifiers, or additional vents can help reduce moisture levels in the property. For cellars, a sump pump or waterproof membrane might be required to handle excess moisture.

Cost of Damp Proofing in Accrington

The cost of treating damp depends on the severity and required treatments. For minor repairs and ventilation improvements, costs might range from £200 to £500. Installing a DPC or waterproofing a cellar can cost between £1,000 and £3,000, depending on the property size and condition.

Challenges Specific to Accrington

In Oswaldtwistle and surrounding areas, older brick properties often lack adequate damp-proofing, making them more susceptible to moisture ingress. The local climate, with frequent rainfall, can exacerbate these issues. Choosing a contractor familiar with Accrington’s building styles ensures effective solutions tailored to the area.

Long-Term Prevention Tips

To prevent future damp problems:

  • Ensure gutters and downpipes are clean and in good condition.
  • Check for leaks in roofs, windows, and external walls regularly.
  • Maintain proper ventilation, especially in kitchens, bathrooms, and cellars.
  • Monitor external ground levels to prevent water pooling against walls.

Benefits of Professional Damp Proofing

Addressing damp early prevents structural damage, improves indoor air quality, and maintains property value. It also reduces the risk of mould, which can pose health risks to occupants.
