Had a bit of an unusual request from a customer she wanted her paths and patios “sympathetically Cleaning not clinically cleaned “ to quote her words , she didn’t want to loose the old stone look but wanted all the slippery algi removing and the colour restored , so we gave it a softwash and light pressure wash , I have always worked on the principal of removing all black spots on paving but today we had to leave a lot of them in place ??? she was delighted with the results , we enjoyed doing something different as well .
