Damp can cause lasting damage to your property if not treated properly — from peeling paint and mould growth to structural decay. At North Building Contractors, we provide expert damp proofing services across Belfast and surrounding areas, helping homeowners safeguard their homes from moisture, improve air quality, and maintain property value.

Types of Damp Proofing We Offer

 

  • Rising Damp Treatment – installation or repair of damp proof courses (DPC) to prevent ground moisture rising through walls.

  • Penetrating Damp Solutions – external wall sealing, gutter repairs, and pointing to stop water ingress.

  • Condensation Control – ventilation improvements, extractor fans, and insulation to reduce moisture build-up.

  • Basement & Cellar Tanking – full waterproofing systems for below-ground rooms.

  • Damp Surveys & Diagnostics – professional inspection to identify the root cause before treatment.

Our Damp Proofing Process

  1. Inspection & Diagnosis – We carry out a full damp survey, using moisture meters and visual checks to pinpoint the cause.

  2. Tailored Recommendations – We provide a clear, written report with options for treatment and prevention.

  3. Preparation & Repairs – Any necessary wall stripping, plaster removal, or external work is carried out before damp proofing begins.

  4. Application of Damp Proofing Systems – Whether it’s DPC injection, tanking, or membrane installation, we apply proven systems to protect your home.

  5. Replastering & Finishing – Once treated, walls are re-rendered, plastered, and finished to restore your home to a clean, dry condition.
