The appearance argument is the one people make. The safety and surface-life arguments are the ones that actually justify it.
Usually yes, for three reasons: algae on a driveway is genuinely slippery, moss and weeds in joints shorten a surface's life, and a clean drive is the first thing anyone sees of a house.
It is less worth it if the surface is failing anyway, if it was cleaned recently, or if the underlying problem is drainage that cleaning will not fix.
A driveway is the largest single thing anyone sees when they arrive at a house, and it is the first. Estate agents put it near the top of the pre-listing list for good reason — it photographs, and unlike most improvements it costs a fraction of what it changes. Whether that matters to you depends on whether anyone is coming to look.
| Situation | Why |
|---|---|
| Surface already failing | Cleaning reveals it, does not fix it |
| Cleaned within a year | Little to gain |
| Persistent drainage problem | Growth returns quickly; fix the cause |
| About to be re-laid | Obviously |
| Heavy oil contamination | Cleaning improves; may not resolve |
| Deep shade with no airflow | Returns fast; consider the frequency honestly |

Cleaning treats the symptom. Clearing overhanging growth that keeps the drive in permanent shade, clearing gutters that discharge onto it, and making sure water drains away rather than sitting will all extend the interval considerably. If you find yourself cleaning annually, the answer is probably shade or water rather than the cleaning.

Usually yes. Algae on a hard surface is genuinely slippery, moss and weeds in joints shorten the surface's life, and a clean drive is the first thing anyone sees of the house.
It can be. Algae is slippery when wet, and a shaded or sloping drive that carries a green film most of the year catches people out.
On a small drive, yes, given time. Domestic washers are far slower, tend to leave lance stripes, and the re-sanding and slurry clearing are the parts most people skip.
Every two to three years for an open sunny drive, annually for one that is shaded, north-facing or under trees.
If the surface is already failing, if there is a drainage problem feeding the growth, or if it is due to be re-laid.
Not when the pressure and technique suit the surface. Tarmac, resin bound and softer stone all need care, which is where most DIY damage happens.
On block paving, yes. Without the jointing sand the blocks lose their interlock and start to move.
Cut back overhanging growth that keeps it in shade, clear gutters that discharge onto it, sweep leaf litter in autumn, and make sure water drains away.
