Professional Damp Diagnosis & Remedial Solutions

At DampLine, we provide specialist damp investigation and treatment services across County Durham. Damp problems are often misdiagnosed, leading to unnecessary work and wasted money. Our approach is different — we focus on accurate diagnosis first, followed by the correct long-term solution.

We offer professional damp surveys and remedial services for homeowners, landlords and estate agents.

Rising Damp

Rising damp occurs when moisture from the ground travels up through masonry due to a failed or ineffective damp-proof course. It is typically found in older properties and most commonly affects ground floor walls.

Common signs of rising damp include:

  • Damp patches to lower walls

  • Tide marks or staining

  • Crumbling or blown plaster

  • Salt contamination on wall surfaces

  • Decayed skirting boards

Our rising damp services include:

  • Full rising damp surveys

  • Identification of DPC failure or bridging

  • Installation of remedial damp-proof courses

  • Removal of salt-contaminated plaster

  • Specialist waterproof replastering systems

Penetrating Damp

Penetrating damp occurs when water enters a property through defects in the external structure. This type of damp is often localised and typically worsens during periods of heavy rainfall.

Common causes of penetrating damp include:

  • Defective brickwork or masonry

  • Failed pointing or render

  • Leaking gutters or downpipes

  • Cracked external walls

  • Poorly sealed windows or doors

Our penetrating damp services include:

  • Internal and external damp inspections

  • Identification of moisture ingress points

  • Masonry and repointing repairs

  • External wall waterproofing

  • Replastering of affected internal areas

Condensation & Mould

Condensation is caused by excess moisture in the air settling on cold internal surfaces. It is one of the most common damp issues in UK homes and is frequently misdiagnosed as rising damp.

Common signs of condensation and mould include:

  • Black mould growth on walls or ceilings

  • Water droplets on windows

  • Musty odours

  • Peeling paint or wallpaper

  • Mould behind furniture or wardrobes

Our condensation and mould services include:
