Henry,
I'm just kidding with ya, don't get yer panties in a bunch...
Actually here's what we typically do.....
If there's standing water, break up the clog so most water drains out.
Scoop out the debris and place into 13 gallon garbage bags.
Rinse the gutters if necessary.
Reseat any gutter nails if necessary.
Any other repairs are on as needed basis and discussed with customer.
Pickup and dispose of any debris that comes out the downspouts.
Haul away debris.
Rinse off any mess we might make on house or surounding area.
If the roofs are steep pitched, we work off a ladder. If they are walkable, and not too high, we work off the roof. Some jobs I will decline because they are too high, too steep, or generally too dangerous that I don't want to be involved with.
Two guys can clean gutters on a typical house in under 30 minutes.
As far as where the stuff goes when a gutter overflows before I clean it, obviously it goes on the ground, and that's often what the customer sees and decides to call someone to take care of it.
