If your home in Salisbury, Poole, Southampton, Bath, Bristol, Wales or elsewhere on the South Coast is showing damp patches away from the ground level, water stains after rainfall, or unexplained moisture spots, penetrating damp may be the issue. At Nordic Damp Proofing Ltd our fully-trained surveyors identify and treat penetrating damp using advanced diagnostic tools — then apply long-term corrective measures to protect your home.

What Is Penetrating Damp?

Penetrating damp occurs when moisture from outside (often wind-driven rain or poor building defects) enters the structure of the building — through cracked bricks, missing pointing, damaged gutters or roof defects — and travels through the wall to the interior. Unlike rising damp, which moves up from the ground, penetrating damp often appears at higher levels and after rainfall. Addressing mounting external water ingress and internal moisture accumulation is critical to avoid mould, timber decay and structural damage.

Suspect your property has penetrating damp? Don’t wait until the damage gets worse. Book a survey with Nordic Damp Proofing Ltd now and let us help you identify the exact issue and repair path.

Our Penetrating Damp Treatment Services

Comprehensive Survey & Diagnosis

Using moisture meters, cavity endoscopes and thermal imaging, we locate the exact paths of water ingress.

Defect Repair & Waterproofing

Fixing the root cause: restoring pointing, repairing gutters/downpipes, replacing damaged roofing or cladding.

Water-Repellent Treatments

Applying breathable masonry creams or membranes to repel rain penetration while allowing the wall to breathe and dry.

Internal Drying & Re-Plastering

After moisture ingress is halted, we dry the wall and re-plaster or finish affected areas to restore your home.

Aftercare & Long-Term Monitoring

We provide follow-up checks and advice on ventilation, maintenance and how to protect your property in the future.
