The work was ok. The reason I have said average is that the workmen left cigarette packets and cans all over the garden as well as sweetie papers. I had to pick them all up. They stole my sweeping brush. They promised to send me a proper invoice and ten year guarantee. I did not receive any and did not get my brush back in spite of asking. They left the old Perspex panels in the alleyway and I had to bring them all in as this alleyway is shared by my neighbour they only came the next day
