Often, and more than people expect. But washing shows you the patio you have — it does not repair it.
Yes, frequently — old patios often come up far better than owners expect, sometimes several shades lighter. Algae, moss, black spot and general grime all clean off well.
What washing cannot do is repair. Cracks, spalling, loose or sunken slabs and failed pointing are revealed by cleaning, not caused by it or cured by it.
| Revealed | What it means |
|---|---|
| Cracked slabs | Were already cracked; now visible |
| Spalling or flaking concrete | Frost damage over years |
| Loose or rocking slabs | Failed bedding — a repair, not a clean |
| Sunken areas | Settlement or washed-out sub-base |
| Failed pointing | Needs repointing |
| Colour variation | Replaced slabs from earlier repairs |
| Wear on the surface | Common on soft stone cleaned repeatedly |

If you are unsure whether an old patio is worth keeping, clean it first. It is the cheapest possible way to find out, it costs a fraction of replacement, and it settles the question with evidence rather than guesswork. If it comes up well, you have saved a great deal. If it comes up poorly, you now know what you are dealing with and can plan a replacement properly — and the cleaning was not wasted, because you needed to see the surface to price the work anyway.

No. Washing reveals cracks, spalling, loose slabs and failed pointing — it does not cause them and cannot repair them.
If damage appears after cleaning it was almost always there beforehand, hidden under growth. Over-washing soft stone repeatedly can wear it, which is a separate issue.
Widespread cracking, significant settlement, multiple rocking slabs, falls running towards the house, or a patio sitting above damp proof course level.
Yes. It costs a fraction of replacement and settles the question with evidence — and you need to see the surface to price a replacement anyway.
Yes, though matching old stone is rarely perfect and the replacement usually shows for a while.
On porous stone it slows re-soiling and helps colour, but it needs a fully dry surface and reapplying every few years.
Sweep autumn leaves off, cut back overhanging growth, clear gutters, fix standing water, and avoid over-washing soft surfaces.
