Airworks Inc.

Obviously this company did not want such a small job. To replace 20 feet of vent they quoted $350 for materials and $134 an hour for labour suggesting that it would likely take them 3 hours to do the job. I priced all the material required at a large box store (636 vent + elbows and glue) maximum of $75.

My point is, if a contractor does not want a job just say so... don't try to snow the customer with an outrageous quote hoping that being naive the customer will take your offer. That's dishonest!
