I have only had two complaints to date and one is due to leaking window frames. I explained to the customer that the amount of water used and the pressure it comes out at, is no more than a sheeting rain shower, therefore, she must already be aware her windows leaked, 'this made her go bright red as she knew her windows leaked'.
The other is from a shop, where I did a sign clean for. Chased the massive £7.50 invoice for 4 months. Finally, when my wife done our banking she called in. We where accused of using a jet wash and flooding her whole shop, which as a result, the wooden floor has now swelled and cracked. The amazing thing is, I actually only used 30 lts of water on that clean and checked the shop for leaks before I left (by looking through the window). After that complaint, I sent the owner a nice letter, stipulating the method used, the amount of water used. I also questioned his management methods!!! As a business man and owner, if a contractor would have carried out that work for me, I would have had him down the next day rectifying his mistakes, so why did he not contact our company the next day and complain about his shop being flooded. At the end of the day, it is just another person trying it on.
Many Thanks
