Bill March 19, 2016 Patios, Sandstone, Walls Expert Patio Cleaning Service - Removal of Algae, Moss, Black Spot Lichen and More Bill March 19, 2016 Patios, Sandstone, Walls Brunswick Park N14 “Bill from the Big Cleaning Machine is a true professional and very knowledgeable when it comes to cleaning and maintaining your driveway and patio. He did a fantastic job on our clay block drive, walls and sandstone patio. He explained exactly what the process involved (depending on level of cleaning required) and also did a couple of test patches. Bill runs his business with integrity and clearly takes a lot of pride in his work. There was no pressure sales techniques applied to book. On the day he was very methodological and clean as he went about his work. The drive and patio came up looking as new. I would whole heartedly recommend Big Clean Machine.” — Raj Mehta, Brunswick Park N14
