Hi Captain,
Never walk away from an area or street just because there is another window cleaner operating. As long as when you door knock if they say they have a window cleaner then leave a card and walk away you will have no problems. I have yet to meet a window cleaner thats does an entire street, it just doesn't happen.
Go back to the lady that wanted your services and take her on your books, thats all fair game mate.
As for your prices comparing to other window cleaners, my advice would be to highlight on your literature that you are REGULAR, RELIABLE, INSURED, PROVIDE REFERENCES, CARE TAKEN WITH GARDENS, 12 MONTH SERVICE. Use bullet points to get your message accross that this is a legitimate business and not some fly-by-night.
I know it is a hard slog but keep going, the results will come eventually. Have you thought about offering your exisiting clients 25% off thier next clean if they introduce you to any of thier friends that need a window cleaner? I did this some years back and it worked well for me.
I am not convinced a price on a ticket is a good idea, thats only my opinion, if I picked that up on my door I would maybe think yeah right, whats the catch or even worse has he been in my garden?
?
Keep it going and don't leave a door un-tapped.
Best wishes,
Trev
