What is Rising Damp?
Rising damp is a form of moisture that travels upward through walls from ground level due to capillary action. It typically affects older buildings without a proper damp-proof course (DPC) or where the DPC has failed. You might notice signs such as tide marks on walls, peeling paint or wallpaper, and a musty smell.
Over time, rising damp can damage plaster, timber, and decorations, and it can even impact indoor air quality. Addressing rising damp early prevents further structural damage and keeps your home dry, healthy, and protected for the long term.
What is the Rising Damp Treatment Process?
1. Survey and Diagnosis
A thorough damp survey is carried out to confirm rising damp, identify moisture levels, and assess any damage.
2. Remove Affected Materials
Damaged plaster, skirting boards, and any contaminated materials are carefully removed to expose the affected wall areas and prevent further spread.
3. Install Damp-Proof Course (DPC)
A new damp-proof course is installed—usually via chemical injection into the masonry to create a barrier that stops moisture from rising through the wall.
4. Replaster and Restore
The walls are re-rendered with a damp and salt-resistant plaster process.
Signs You Have Rising Damp in Your Home
Tide Marks on Walls
Look for horizontal, discoloured lines or stains, usually up to about one metre from the floor. These are caused by water rising through the wall and depositing salts from the ground.
Peeling Paint or Wallpaper
Moisture behind walls can cause paint to bubble and flake, or wallpaper to lift and curl at the edges. This often starts near the skirting board and works its way upward.
Damp or Musty Smell
A persistent, musty odour, especially noticeable in basements or ground floor rooms, often indicates trapped moisture and poor ventilation associated with rising damp.
Salt Deposits
White, powdery substances may appear on the surface of plaster or brick. These are mineral salts left behind as damp evaporates, a clear sign moisture is travelling through the wall.
Crumbling Plaster or Timber
Plaster may become soft, flaky, or begin to disintegrate, while wooden skirting boards can swell, crack, or rot due to long-term exposure to moisture.
Cold or Damp Wall Patches
Walls affected by rising damp often feel noticeably cooler or damp to the touch compared to surrounding areas. These patches may not dry out, even with heating.

Booking professional rising damp treatment services ensures the problem is accurately diagnosed and effectively resolved.

They also identify any underlying issues, such as poor drainage or bridged DPCs.
Frequently Asked Questions
What exactly is rising damp and why does it happen?
Rising damp is a form of moisture that travels up from the ground through brickwork and masonry by capillary action. It usually occurs when a damp proof course is missing, damaged, or bridged. Older homes are particularly prone to rising damp due to age and construction methods. At Home Energy Save GB, we regularly identify rising damp during our free damp surveys and provide clear advice on the most effective long term solution.
What are the early signs of rising damp in a house?
Common signs of rising damp include tide marks on internal walls, crumbling or blistering plaster, peeling wallpaper, and skirting boards that appear rotten or damaged. You may also notice a musty smell near ground level walls. These symptoms typically worsen over time if left untreated. Home Energy Save GB offers free damp surveys to confirm whether rising damp is present and explain what is causing the issue.
How is rising damp different from condensation or penetrating damp?
Rising damp comes up from the ground, while condensation is caused by excess moisture in the air and penetrating damp enters through walls or roofs. Rising damp usually affects the lower part of walls and produces salt deposits and tide marks. Misdiagnosis is common, which is why a professional assessment matters. At Home Energy Save GB, our free damp surveys are designed to correctly identify the source of moisture before any treatment is recommended.
Is rising damp more common in older properties?
Yes, rising damp is more common in older homes, particularly those built before modern damp proof courses were standard. Some properties may never have had a damp proof course installed, while others have systems that have failed over time. Home Energy Save GB regularly works with homeowners in older properties and uses free damp surveys to assess whether rising damp is present and what remedial work is required.
How do you confirm that rising damp is the real issue?
Proper diagnosis involves inspecting internal walls, checking moisture levels, identifying salt deposits, and examining the condition of the damp proof course. Visual signs alone are not always enough. At Home Energy Save GB, our surveyors carry out free damp surveys that look at the full picture of your property, ensuring rising damp is correctly identified rather than confused with condensation or other moisture problems.
Is rising damp expensive to fix?
The cost of treating rising damp depends on the severity of the problem and the size of the affected area. Early intervention is usually more cost effective than delaying action. A proper diagnosis ensures the correct solution is applied rather than wasting money on temporary fixes. Home Energy Save GB provides free damp surveys so homeowners can understand the issue and potential costs before committing to any work.
