Patio power washing in Kerry: remove green algae and bring back the original colour
Green algae is one of the main reasons patios in Kerry look tired long before the surface is actually worn out. At DNK Cleaning, we deliver patio power washing in Kerry with a focus on visible restoration and long-term surface care. The aim is straightforward: remove organic growth properly, lift embedded dirt, and bring back the original colour — without damaging jointing, edging, or the surface finish.

Why Patios Go Green in Kerry
Patios across Kerry often face a combination of conditions that accelerate algae and moss growth:
- Constant moisture from frequent rain and mild weather
- Shade from hedges, walls, trees, and north-facing gardens
- Poor drainage that leaves standing water in low spots
- Porous surfaces that hold grime and encourage staining
- Seasonal build-up of leaves and debris that traps dampness
Green algae is not only cosmetic. It forms a slick layer that increases slip risk, particularly on steps, ramps, and smoother paving.

What Patio Power Washing Removes
A proper patio clean goes beyond “making it look brighter.” With professional power washing in Kerry, we typically remove:
- Green algae film and deeper staining
- Black spot and weather marks
- Ground-in mud and traffic dirt
- Lichen and light moss growth
- Grime around edges, gates, and seating zones
If you have tried a quick rinse and the green returns within weeks, it usually means the growth wasn’t fully treated, or residue remained in pores and joints where moisture sits.
Our DNK Cleaning Approach to Power Washing in Kerry
Not every patio should be blasted at maximum pressure. Different materials respond differently, and the wrong method can create permanent damage. Our process is built around assessment and control.
Surface inspection and risk check
Before washing, we check:
- Patio material and surface finish
- Jointing condition (sand, mortar, compound)
- Drainage and water flow direction
- Cracks, loose slabs, and edging stability
- Nearby features (doors, vents, outdoor sockets, painted surfaces)
Targeted pre-treatment for algae
For green algae and organic staining, pre-treatment matters. It helps break down growth so the wash is more effective and reduces the need for aggressive pressure.
Controlled wash for consistent colour
We work methodically to avoid striping and patchy results. Consistent distance, controlled flow, and correct nozzle selection are what separate “clean enough” from “restored.”
Detail work on high-traffic zones
Edges, steps, and dining areas tend to hold the most grime. We focus on:
- Perimeter lines and borders
- Step fronts and risers
- Door thresholds and connecting paths
- BBQ zones and outdoor seating areas
Rinse and final check
We leave the surface clear, safe to walk on once dry, and visually even — so the restored colour looks natural, not over-etched or roughened.

Common Mistakes That Damage Patios
Many surface problems start with DIY pressure washing. The most frequent issues we see include:
- Etched concrete (“tiger stripes” and rough patches that won’t disappear)
- Blown-out jointing that leads to weeds and slab movement
- Water forced under slabs, gradually lifting edges
- Uneven results caused by inconsistent technique
- Fast regrowth because algae was rinsed, not treated
Professional patio cleaning is not just stronger equipment. It is controlled cleaning that protects the surface.
How Long Do Results Last?
Results depend on shade, drainage, and surrounding greenery. Most Kerry patios stay noticeably cleaner for months, especially when:
- Drainage is improved in problem areas
- Leaf build-up is cleared regularly
- Standing water is reduced or eliminated
If your patio sits in heavy shade or near dense planting, algae can return faster. In those cases, scheduled cleaning is often the most cost-effective way to maintain both colour and safety.
Power Washing in Kerry: When to Book Patio Cleaning
The best times are typically:
- Spring to clear winter growth and refresh the garden area
- Early summer before entertaining season
- Autumn after heavy leaf fall and storms
- Any time the surface becomes slippery or discoloured
If your patio looks green, it is already holding moisture. Cleaning sooner helps prevent deeper staining.

Patio Power Washing FAQ
How much does patio power washing in Kerry cost?
Pricing depends on patio size, surface type, severity of algae staining, access, and whether jointing needs extra care. The most accurate quote comes from a quick assessment.
Will power washing remove green algae completely?
In most cases, yes. Green algae is organic growth and responds well to proper pre-treatment and controlled washing. Heavy staining in porous stone may need additional attention for the most even finish.
Can pressure washing damage paving slabs?
It can if done incorrectly. High pressure, the wrong angle, or poor technique can damage jointing or mark softer stone. DNK Cleaning uses a surface-appropriate approach to protect your patio.
Do I need to be home during the service?
Not always. If we have safe access and an agreed plan, many customers choose to be out while we work.
Will weeds stop coming back after cleaning?
Cleaning removes existing growth and debris, but weeds usually return if joints are open or the area collects dirt. Good jointing and basic maintenance reduce regrowth.
How long does patio power washing take?
Most standard patio cleans are completed in a single visit. Larger areas or heavy build-up may take longer due to pre-treatment and detailed finishing.
Do you offer power washing in Kerry for paths and driveways too?
Yes. Many customers book patios together with paths, steps, entrances, and driveways for a consistent finish across the property.
