Thanks for the reply dazmond, I have only had one customer mention them and I quickly ran around the ground floor windows with some cif to keep them happy but it had me thinking that I couldn't do this with everyone.
In future I'll just say that it's priced for a general clean and removal of these marks is a PVC restoration clean or something along them lines.
Cheers!
Its their problem, not yours. We have 1 house which is really bad. We scrub the black off the frames as best we can but the stain is still there. A couple of days later its black again.
Cleaning the frames white can only be done by hand. And as I said, they will be black again in a few days.
Your reply could be; "yes Madam, we also offer a frame restore service which will mean us doing it by hand. We currently offer this service at £10.00 a window and £12.00 for each door. We could do it next time we are around to clean the windows. Unfortunately, as the seals have perished we can't guarantee that the frames will be white for very long. Would you like us to book the job in then?"
I'm sure you know what the reply will be. But from then on that won't question the frames again.
Solution - customer to replace window seals. If the customer doesn't like your service, then tip your proverbial cap and thank them for their previous custom. Chances are you have already replaced them with a customer whose seals don't leach black all over the frames.
