Rising Damp Treatment for an Internal Wall in Ulverston LA12
There is evidence of rising damp on an internal wall on the lower ground floor of my property in Haverthwaite, Ulverston. Signs include salts on the wall and blistering plaster. I’m looking for confirmation of the cause and a solution to address this issue.
Expert Advice on Diagnosing and Treating Rising Damp
Rising damp occurs when moisture from the ground moves up through walls due to capillary action. Common in older properties or homes with damaged damp proof courses, this issue can lead to visible damage like salts on the surface, peeling plaster, and potential structural concerns if left untreated.
Steps to Confirm the Cause of Rising Damp
A professional damp survey will identify the root cause of the problem through the following steps:
- Visual Inspection: Assessing the affected wall for signs like tide marks, blistering, or white salts (efflorescence) which indicate moisture and mineral deposits.
- Moisture Readings: Using a damp meter to measure moisture levels within the wall to confirm rising damp.
- Checking Damp Proof Course (DPC): Inspecting the DPC to determine if it’s damaged, breached, or missing.
- Assessing Nearby Features: Examining external drainage, ground levels, and pipework for contributing factors such as water ingress or high external ground levels.
Solutions for Rising Damp
Once the cause is confirmed, the following treatments can resolve the issue:
- Injectable Damp Proof Course: A modern DPC is injected into the wall at ground level to form a barrier against rising moisture. This is often the most effective solution for older properties.
- Plaster Removal and Replastering: Affected plaster is removed to eliminate salts and replaced with a water-resistant plaster or render to protect the wall.
- External Groundwork Adjustments: Lowering external ground levels or improving drainage to prevent water accumulation near the property.
Cost and Timeline
The cost for rising damp treatment depends on the size of the affected area and the solution required:
- Damp Proof Course Injection: £40–£60 per metre.
- Plaster Removal and Replastering: £15–£25 per square metre.
- Additional Groundworks: Costs vary depending on scope, typically starting from £500.
Most rising damp treatments can be completed within 3–5 days, including drying time for replastering.
Benefits of Resolving Rising Damp
Addressing rising damp promptly ensures:
- Prevention of further structural damage.
- Improved indoor air quality and reduced risk of mould growth.
- Enhanced aesthetic appearance with smooth, dry walls.
Preparation for the Homeowner
Before the survey or repair work begins:
- Clear furniture and belongings from the affected area to provide access.
- Document signs of damp with photos for your records.
- Ensure the exterior of the property is accessible for inspection if external factors are suspected.
