West of Ireland properties face constant wind-driven rain and salt-laden air that leaves black algae streaks on render and green moss on paving within a single winter. Pressure washing restores the original colour and texture while avoiding the water ingress that trapped growth can cause in older stone and blockwork common in the region.
The work typically covers concrete driveways, block paving, natural stone paths, external render, yard slabs and agricultural outbuildings. Operators adjust pressure and nozzle choice to suit each material so that pointing remains intact and softer surfaces are not etched.
Access on sloping sites or narrow laneways around Galway and Mayo often dictates the method, with lightweight equipment carried in by hand rather than relying on large vehicles. Run-off is directed away from drains and watercourses to meet local environmental expectations.
Seasonal Timing
Scheduling before the wettest months allows surfaces to dry fully and reduces immediate re-growth of algae on north-facing walls.
Technician insight
In Galway the thing that catches most people out with pressure washing is the age of the pointing on 1970s and 1980s block driveways; once the joints start to erode the water finds the sub-base and you end up widening every gap instead of cleaning the surface.

How it works
- 1
Site Assessment
Walk the surfaces to note material type, slope, drainage points and extent of growth.
- 2
Protection and Preparation
Cover nearby plants, seal gullies and set up containment for run-off.
- 3
Controlled Washing
Apply appropriate pressure and cleaning solution, working in sections to avoid streaking.
- 4
Final Rinse and Inspection
Rinse thoroughly and check that joints and edges are clear before leaving site.
Pricing
Scope and cost depend on surface area, build-up depth, access difficulty and whether soft-wash treatment is required alongside pressure washing.
