Your driveway or patio, looking like new again.
Green algae, moss, and lichen don't just look bad - they create a genuine slip hazard, particularly on wet autumn and winter days. A professional jet wash removes years of built-up growth, restores the original colour of your surfaces, and dramatically improves the safety and appearance of your property. Using commercial-grade equipment and biodegradable pre-treatment, the results are not comparable to a domestic pressure washer hired for the weekend.
Surfaces we clean
How we work
Before any water touches the surface, we check the surface type, condition of pointing and joints, any loose or cracked material, and drainage direction. This sets the right pressure, nozzle, and pre-treatment for the job - and prevents damage.
A professional-grade algaecide is applied and left to dwell for 10-30 minutes depending on the severity of growth. This breaks down algae, lichen, and moss at the root. Without this step, organic growth returns significantly faster - usually within weeks rather than months.
We use commercial surface cleaners that deliver consistent, streak-free results across flat surfaces - consumer pressure washers leave visible cleaning lines. Our machines operate at significantly higher pressure and flow rates than domestic equipment, removing contamination that a hired machine simply cannot shift.
After cleaning block paving, jointing sand is partially washed out and must be replaced. We use kiln-dried jointing sand to restore structural integrity and prevent weed re-establishment. Skipping this step is the most common complaint about cheaper operators.
A residual weed inhibitor can be applied to block paving joints after re-sanding. This significantly reduces regrowth - though annual maintenance is recommended to keep surfaces in the best condition.
Why not just hire a machine?
Consumer pressure washers (the type sold in DIY stores for £150-£400) run at 1,300-1,800 PSI with a low water flow rate. Professional commercial machines operate at up to 4,000 PSI with much higher flow rates - removing contamination that a domestic machine simply cannot shift in a reasonable time.
