Hello all, Been a succesful first year. Up to 25 accts so far and still getting calls. I do some odd jobs as well. The other day, I had a customer ask me what I would charge him for his winders to be washed. I offer the service, but never really expected to get a residential market. Told him $5 a window, exterior only and he jumped all over it. Did his house and daughters house in less than an hour for $70. Is this an untapped market????? Anyone do any window washing residentially?
