Why Pressure Washing Works
Northern Ireland’s damp climate creates ideal conditions for moss, lichen, algae, and dirt to build up on patios, driveways, walls, and paving. Over time, this not only looks bad but can create slip hazards and damage your surfaces.
Our high-pressure washing service removes:
Moss, algae, and mildew
Dirt, mud, and pollution build-up
Oil stains and tyre marks
Paint flecks and residue
Chewing gum, bird droppings, and general grime
With the right nozzle, pressure setting, and experience, we clean effectively without damaging the surface — leaving you with clean, safe, and visually appealing exteriors.
