What Causes Damp in Wirral?
Damp occurs when moisture enters a property faster than it can escape. Main causes include:
- Rising Damp β moisture rising up through walls due to a failed or missing damp-proof course (DPC).
- Penetrating Damp β rainwater entering through damaged brickwork, render, roofs or cavities.
- Condensation β moisture from cooking, showers, drying clothes and breathing meeting cold surfaces and forming water droplets and black mould.
- Basement Damp & Hydrostatic Pressure β underground moisture pushing through walls/floors.
- Cavity Wall Bridging β debris or insulation bridging across cavities and bypassing the DPC.
- Hygroscopic Salts β salts within plaster attracting moisture even when surfaces appear dry.
Types of Damp We Treat in Wirral
Rising Damp
Groundwater travels up walls by capillary action. Symptoms include tide marks, salt deposits, flaking plaster and damp skirting boards.
Treatment: Chemical DPC injection, removal of salt-contaminated plaster, waterproof render or renovating plaster, and full plaster skim.
Penetrating Damp
Caused by defects in roofs, walls, gutters, chimneys or pointing. Appears as damp patches on walls or ceilings, often after rain.
Treatment: Repairing external defects, repointing brickwork, applying Stormdry water-repellent, and restoring internal finishes.
Condensation & Black Mould
Warm moist air hits cold surfaces and forms condensation. If humidity stays high, black mould appears (commonly in bedrooms, bathrooms, kitchens).
Treatment: Positive Input Ventilation (PIV), DMEV fans, trickle vents, vapour barriers, thermal insulation and moisture control.
Basement & Cellar Damp (BS8102 Waterproofing)
Below-ground rooms are prone to constant moisture pressure.
Solutions: Cementitious tanking systems, cavity drain membranes, perimeter channels and sump pumps β fully compliant with BS8102:2022.
Cavity Wall Damp & Bridging
Remedy includes removing debris, installing weep vents, lowering external ground levels and reinstating correct cavity drainage.
Timber & Structural Damp Services in Wirral
Wet Rot & Dry Rot
Timber decay caused by excessive moisture.
- Wet Rot: Soft, spongy wood.
- Dry Rot: More serious β fungus spreads through walls and timber.
Treatment: Remove damaged timber, apply fungicidal solution, improve airflow and correct moisture source.
Wood Rot & Timber Preservation
Repair or replace damaged joists, beams and floors. Apply timber preservatives and improve ventilation to prevent reoccurrence.
Resin Beam End Repairs
Cost-effective alternative to full beam replacement. Decayed beam ends are cut back and replaced using high-strength resin and reinforcement bars.
Woodworm Treatment
Beetle larvae bore into timber, leaving exit holes and frass.
Treatment: Survey to identify species, apply professional insecticide treatment, replace severely damaged wood if required.

How do I know if it’s rising damp or penetrating damp?
- Rising damp: tide marks up to 1m, salts, skirting board rot.

Can I paint over damp or mould?
No. It will return unless the moisture source is fixed first.
What causes condensation?
Moisture from breathing, showers, cooking, drying clothes indoors. If it hits cold surfaces, it becomes water droplets β mould.
