Jet Washing in Darlington

Block paving, tarmac, and concrete driveways all pick up oil residue, moss between joints, and general dirt over time, block paving in particular can look tired once the joints between blocks fill up with moss and algae rather than sand. We clean the full surface and, where needed, can refill joints with fresh sand once cleaning's done, which also helps stop weeds establishing again as quickly.

Natural stone, concrete slabs, and block paving patios are prone to the same build-up as driveways, often worse in shaded or damp corners of a garden where algae has more chance to establish. We match the pressure and method to the material, since some natural stone is softer and more porous than concrete or man-made paving, and needs a gentler approach to avoid damaging the surface itself.

Garden paths, especially ones that see less foot traffic than a driveway, are often the worst affected by moss and algae simply because they don't get walked on or weathered enough to wear it away naturally. Cleared paths are also safer, moss and algae get genuinely slippery in wet weather, which matters more on a path than most people think about until someone's nearly gone over on it.

Timber decking needs particular care when jet washing, too much pressure or the wrong technique can strip and damage the wood fibres themselves rather than just removing surface dirt and algae. We use appropriate pressure and technique for decking specifically, and it's often worth having decking sealed or treated shortly after cleaning, since a freshly cleaned surface is more exposed to weather until it's protected again, see our Driveway, Patio & Decking Sealing page for that side of things.

The biggest risk with jet washing isn't leaving dirt behind, it's using too much pressure on a surface that can't take it, block paving joints stripped of sand, softer natural stone pitted or etched, or timber decking damaged at the fibre level. We assess the material before starting and adjust pressure and technique accordingly, rather than treating every surface the same way.

Businesses with car parks, forecourts, or shared driveway areas often need jet washing on a scheduled basis rather than as a one-off, particularly where a tidy, well-maintained exterior matters for how customers perceive the site. We can set up a regular cleaning round for commercial premises alongside any other grounds work we're already doing there.

Where a driveway or patio sits close to borders, lawn, or drains, we're mindful of run-off, particularly where any treatment product is being used alongside the wash itself. We use appropriate techniques and, where relevant, products that minimise impact on surrounding planting and avoid sending anything harmful into drains that lead to watercourses.
