Swindon & Wiltshire
Patio cleaning in Swindon for Indian sandstone, limestone, slate, porcelain and concrete.
Patios are where the most expensive mistakes happen. Natural stone is softer than people assume, and a jet wash in the wrong hands will scar Indian sandstone permanently. We work out what your patio is made of first, then clean it the way that surface wants to be cleaned.
How we do it
Indian sandstone is porous and soft. Hit it with a turbo nozzle and you leave permanent swirl marks that no amount of later cleaning will take out. On natural stone we lead with a biocide soft wash and use pressure sparingly, which takes longer and looks far better.
Those stubborn black dots on sandstone are lichen, and they are not dirt. Pressure will not move them without damaging the stone. They need a specific treatment and a dwell time, and sometimes a second visit. We will tell you upfront if your patio has it, because it changes the job.
Cleaning finds every weak joint you have. We check the pointing before we start and tell you what is likely to blow out, rather than discovering it together halfway through.
Borders get wet down before and rinsed after, and we will tell you how long to keep pets off. The treatments are safe once dry but we would rather you knew the timings.
On the day
Identify the surface and test a discreet area before committing to a method.
Protect and wet down surrounding planting.
Apply the appropriate soft wash treatment and let it dwell.
Clean evenly across the whole patio, controlling pressure to suit the stone.
Re-sand joints where needed and rinse everything down.
Questions
Yes, and it is the surface we are most careful with. Sandstone is soft and porous, so we lead with a soft wash treatment rather than pressure. Most of the damaged patios we get called to have been done with a turbo nozzle by someone who did not know what the stone was.
Lichen. It bonds to the stone rather than sitting on it, so it needs a treatment and dwell time rather than pressure. Badly affected patios sometimes need a second application. We will say so when we quote rather than after.
We wet down borders before we start and rinse afterwards, which is what protects them. Tell us about anything you are particularly attached to and we will cover it.
