Personally, my belief is that Check-a-Trade might be useful to homeowners who want some big building project undertaken, some plumbing or electrical work done.
I can't see why Mr Ordinary Joe Bloggs would want a window cleaner to be checked out unless there are some very extenuating circumstances.
The vast majority of our work has come from word of mouth and personal recommendations. Any new customers come from recommendations, as we don't canvass any more.
We have never had our integrity questioned. If someone doesn't like us, for what ever reason, they discontinue our service. No hard feelings. That's their right, in the same way it's our right to discontinue providing a service to them.
