These photographs are from a client in Caistor whose Sandstone Patio hadn’t been cleaned for years and was covered in blackspot and sap from overhanging trees from the churchyard next door. It was so dirty and un-inviting they had decided it was overdue a deep clean and so got in touch with Tile Doctor to have it restored, if possible. Deep cleaning a patio is certainly cheaper than replacing it so it’s always worth investigating that option first.

Sandstone Patio Before Cleaning Caistor

After discussing the patio over the phone, I made an appointment to visit the property and survey the patio. I could see that the Sandstone had turned black with all the absorbed dirt and blackspot staining and was unrecognisable from what it once was.

Undeterred I was confident of being able to renovate its condition and worked out a quote for the work which shouldn’t take longer than a day. Happy with the quote and the prospect of enjoying the patio again in time for the summer we set a date with an eye on the weather forecast.

Deep Cleaning a Sandstone Patio

There was a lot of dirt to remove so I started by giving the whole area a thorough jet wash using an industrial pressure washer. The machine generates pressurised hot water and worked well to cut through the dirt. It comes with several wand accessories including a spinner attachment that is the most efficient way to cut through the dirt.

With most of the surface debris removed I followed up with an application of Tile Doctor Patio & Driveway Cleaner which was left to soak into the stone for some time before being rinsed off with the pressure washer. This dwell time is important as the strong chemicals need time to break down the staining and especially the blackspot which ran deep into the Sandstone.

I had to repeat the process several times to get rid of all the staining experimenting with different dwell times on each occasion but as can be seen in the pictures it made an amazing difference. Just goes to show that a little patience can make a big difference.

My client was blown away in the transformation and most relieved that they wouldn’t have to look at replacing it.

I’ve mentioned this before but it’s worth knowing that Tile Doctor can deal with all types of tiles, both internal and external. We do not just tackle tiles, patios form a lot of our work in the spring and summer time, along with driveways. Cleaning and recolouring of grout is also a popular request for internal wall and floor tiles.
