They came out in a reasonable amount of time, but charged $59 for the service call plus they wanted $180 to run a snake through a 10 foot piece of drain pipe to determine if it was frozen. It was a drain pipe (which shouldn't be frozen since it's non pressurized) and if it turned out to be damaged, they would have charged more to fix the problem. So here's the rundown:
$60 to drive to the house + $180 to run a snake for 3 minutes = $240
I sent them away and bought a snake at Home Depot for $27. Hopefully that clears out the clog in the drain, but either way I'm glad I didn't move forward with them since their prices are very high. If you're looking at having them clear your drains, I'd recommend going to a local plumber and not a franchise like this.
UPDATE: after reading this review, I was contacted by Ben Franklin (the company, not the man) and they refunded the service charge. So in response, I upgraded them to two stars from one.
