Hi
I just moved to Seattle and we bought a treadmill which we've kept in
the garage. Now the garage has a 15amp circuit but the treadmill needs
a 20 amp one. We asked an electrician to give us a quote to change from
15 to 20 and he has quoted $600 for the wall closet to the door and
$900 for a wall further.

I am novice at this, could someone tell me what would be a good price
to pay for this?

Thanks

I agree with the op about checking the gauge of the wire first. Is it
12 or 14?
You could possibly have #12 wire (20 amp) on a 15 amp breaker. In that
case all you need to do is switch out the breaker to a 20 amp.
