Rising Damp Treatment in Carshalton SM5

Q: What are common signs of rising damp?

Possible signs include damp patches low on walls, salt deposits, peeling decorations, damaged plaster, musty smells and deterioration near skirting level. These symptoms should be investigated because they can have more than one cause.

Carshalton Rising Damp Case Study

This Carshalton SM5 project involved damp symptoms affecting the lower section of internal walls. A diagnosis was required before specifying treatment because low-level moisture may be caused by rising damp, a bridged damp proof course, high external ground levels, leaking services or penetrating moisture.

The investigation considered the existing damp proof course, external paving and soil levels, the distribution of moisture within the masonry, salt contamination and the condition of the plaster.

Where the evidence supports rising damp and the existing DPC is absent or ineffective, the remedial specification can include a new damp proof course, removal of contaminated plaster and a suitable salt-resistant reinstatement system.

Signs Investigated

Damp staining around the lower sections of walls
Damaged, hollow or deteriorated plaster
Salt deposits and contaminated wall finishes
A potentially defective or bridged damp proof course
External paving and ground levels relative to the DPC
The moisture profile across the affected masonry

How the Rising Damp Work Was Approached

The final treatment must follow the evidence found at the property. The typical sequence used for this type of Carshalton remedial project is:

Investigation

Inspect external walls, ground levels, rainwater details and internal symptoms to identify the likely moisture source.

Preparation

Protect the work area and remove skirtings plus defective or salt-contaminated plaster where required.

DPC Treatment

Install a suitable remedial damp proof course where the investigation confirms that DPC treatment is appropriate.

Reinstatement

Apply the agreed plaster or render specification and prepare the wall for decoration after sufficient drying.

Rising Damp in Carshalton Properties

Carshalton includes Victorian and Edwardian houses, inter-war properties, later homes and converted buildings. The construction, age and subsequent alterations to each property affect how damp should be investigated.

Raised patios, driveways, flower beds and paths can sometimes reduce the clearance below a damp proof course or bridge it. Defective rainwater goods, external pointing, plumbing and ventilation should also be checked before attributing every damp patch to rising damp.

Atruss Preservation provides damp investigation, rising damp treatment, new DPC installation, high-ground-level solutions, damp plaster repairs, waterproofing and related property-preservation work throughout Carshalton and the London Borough of Sutton.
