Rising Damp Treatment

Rising damp occurs when moisture travels up through your walls from the ground. It is common in older Dartford properties without a functioning damp proof course (DPC). We install chemical DPC injections and apply tanking slurry to affected walls, providing a permanent barrier against rising moisture. We also replaster with specialist waterproof plaster to restore the wall finish.

Penetrating Damp & Roof-Related Damp

Penetrating damp enters through cracks in external walls, failed pointing, damaged rooflines, or roofing defects. As roofing specialists, Reilly's Roofing is uniquely placed to identify and fix damp that originates from the roof or roofline – the most common source of damp in properties across Dartford and Kent. We treat both the external cause and any internal damage.

Identifying the true cause of damp is critical – and is where many other contractors fall short. We carry out a thorough damp survey of your property before recommending any treatment. This includes moisture readings across walls, visual inspection of the roofline, guttering, external walls, and roof coverings. Our written report explains exactly what’s causing the damp and how we propose to fix it, so you understand the work fully before any costs are committed.

Service Benefits

Damp treatment is most effective when the root cause is correctly identified first. Our experienced team carries out detailed damp surveys across properties in Dartford and Kent, distinguishing between rising damp, penetrating damp, and condensation to recommend the right treatment every time.

Service Benefits

After treatment, we repair and redecorate affected internal walls using specialist waterproof plasters and renders. The result is a dry, clean wall surface that looks good and stays dry – giving you the confidence that your damp problem has been solved properly and permanently.

What are the signs of damp in a property?

Common signs include damp or wet patches on walls or ceilings, peeling wallpaper or bubbling paint, black mould growth, a musty smell, tide marks or white salt deposits on walls, rotting skirting boards, or a damp smell in the loft. If you notice any of these, contact us for a free damp survey.

Rising damp travels upward from the ground through walls and is typically found in older properties without an effective damp proof course. Penetrating damp enters horizontally through defects in walls, rooflines, or roof coverings. Both require different treatments. We diagnose accurately before recommending any solution.

Not at all. In our experience across Dartford and Kent, the majority of damp issues in older properties originate from external causes – failed rooflines, cracked chimney stacks, blocked gutters, or missing roof tiles. As roofing specialists, we often find and fix the external cause of damp that other damp-proofing companies miss entirely.
