Con roofs now make me loadsa £££,s

There isnt an option for voting that covers what I do.
Here it is: I do the first clean say £50 to £150 depending on size and condition. Then I offer a spring and Autumn clean at half the price of the 1st clean to keep em up to scratch. Now.. here is the trick. I dont do the Cons during normal window cleaning conditions. I do them in anything over moderate rainfall. The custies dont have a prob about having them done on a specific day or even week. That way I am out and about earning very good money while most other WC's are sittin at home. The work is dead easy to get from ur existing customers.
Don't offer this as an option every time. 1 it will seem very expensive to the custy and 2 it will slow you down far too much at what will be a very low rate when you actually work out what it gains you.
