There is no such thing as an average price per sq. ft. for starters. I will consider if I think the job is going to be fairly easy and may shoot a discount. A lot of pews are stationary and it's a bit of a pain for me to go between them and get under every single pew while some churches now use seats and they can remove them all out of the way for you the night before you clean. I know my area pretty well and I know if I go too high I may as well have not bothered to give the estimate. At the same time if I go too low I may as well have not done the job. I suggest shooting them a price in accordance with any other business. I almost never give a discounted price to businesses, but I may to a church if they haven't let it get really bad. Most of the church carpets I've done have been fairly easy cleaning.I’ve been asked to bid on cleaning a church what is the average price per square feet?
