Did a gutter cleaning job today, and noticed the customer had just had her drive pressure washed. I told her it would it would be a good idea to get it sealed as the sand was washing away . . . .. she told me she had sealed three months !
She saw him physically spray the area, but you can see from the picture he must have been using water.
Must be around 60 m2 he had done, and he charged her £900, and told her it will never need sealing again
Oh, and he promised her a receipt but has forgotten, and not answering his phone.
