Rising Damp Treatment in a Barnsley Property

Failed damp proof course, blown plaster and mould at skirting level — diagnosed, treated with a new injected DPC and salt-neutralising plaster, and left dry and ready to decorate.

Blown plaster and mould at skirting level before treatment

Classic signs of rising damp

This property was showing textbook rising damp: blackened, blown plaster along the skirting line, damp staining creeping up the walls, and visible mould at the base of several rooms.

The original damp proof course had failed, allowing moisture to track up through the brickwork and into the internal plaster.

Plaster stripped back to brick to expose the full extent of the damp

Stripped back to brick for a clear picture

Our team stripped the affected plaster back to brick to fully assess the damage. Once exposed, the brickwork confirmed rising damp with no effective barrier in place.

This gave us a clear view of exactly how far the damp had travelled and let us plan the treatment accurately, rather than guessing at the extent of the problem. It is the same diagnosis-first approach we bring to every damp survey.

DryZone damp-proofing cream ready for injection into the affected walls

A new injected DPC and salt-neutralising plaster

We installed a new chemical damp proof course by injection along the affected walls, using DryZone damp-proofing cream to create a consistent, long-lasting barrier against rising moisture.

Once the new DPC was in place and the wall allowed to begin drying, we applied a specialist salt-neutralising renovation plaster. This step is essential: it stops residual salts left behind by years of damp from breaking down the new plaster finish.

Why the plaster matters

Injecting a new damp proof course is only half the job. Years of rising damp leave hygroscopic salts behind in the wall, and if the old plaster is simply skimmed over, those salts draw in moisture and the staining and blowing return.

The salt-neutralising renovation plaster creates a clean barrier between the wall and the finished surface, so the repair lasts and the wall is ready to take paint or wallpaper properly.

New salt-neutralising plaster applied and ready for decoration

Dry walls, ready to decorate

The result: dry, structurally sound walls ready for redecoration, with a long-term damp proof course in place to stop the problem recurring.

The salt-neutralising plaster gives a clean, stable surface that will take paint or wallpaper without the staining and blowing seen before treatment.
