How do you know its a so called ladder monkey as it could be that whoever that has undercut you might been cleaning longer than one thinks, and all they doing is expanding there business.
And he might worked out a price structure where he doesn't need to over price his business.
Like myself I use both methods and offer the customer what they are looking for a good reliable and reasonable priced for window cleaning as many customers do think they are getting ripped off for our service.
And most window cleaners who use wfp most would of started off as trad cleaners.
And like any business its dog eats dog out there on those streets, its fair game for all as you will gain some good experience from this as no matter how long you have a regular customer they aren't as loyal as you and me are to this business.
Where one leaves you, you will gain with another one in which might be higher or lower price but they normally tell there friends and family so where one customer gain can lead into neumorous of customers.
Sorry it is long winded this is life as a window cleaner as we know it
