We got an estimate for our driveway pour last week and lets just say it was my magic number. We agreed, shook hands, got it in writing and, yesterday, they came by and graded the land and laid the forms. During that work I had to take my cat to the vet. While we were there, I got a call from the contractor:

“Hey, I wanted to let you know that we re-measured after laying the forms and I’m not sure if something was in the way, or if we just missed something, but there’s an extra 400 sq ft I didn’t account for. I won’t charge you for the extra labor but I’m going to need $600 for the extra concrete.”

How the hell am I supposed to deal with this? We went with him on a recommendation and he was the best estimate. This extra cash puts him above some of the other estimates we got but he’s already done a good deal of work. We also don’t have that $600 to toss at him Friday (when the pour happens).

It sucks that his estimate was off but how the hell do you miscalculate by 400 square feet? Should I play Good Guy Steve and get him the extra six bills? Meet him somewhere in the middle? Douchebag Dave it and say “Well we’re paying what’s on this sheet here because this is what we signed off on” and let him eat the total loss?
