We send every single customer a Christmas Card and have done for the last 6 years. They are qulatity cards and is our way of saying thank you for their business throughout the year, we also enclose flyer for pressure cleaning and other services we offer.
Every year we get extra business from existing customers who did not know the other services we offer (even though it's on our van and leaflets they already have)!
Only ever had positive good comments from our customers with regards to sending out cards.
For us it works.
