I have a new biweekly client that I got during the hot summer months. During most of the season, the grass didn't grow fast enough to cut it more often. Now, with the morning dew, and lots of recent rain, the grass is growing faster. I find myself mowing over the same lawn twice in one visit to break up the clumps and to get it to look nice. I can't see leaving the property with clumps of grass all over the yard. Should I charge these customers more $ because of my extra time & gas to go over it twice? Also, If I can cut a property in 1 hr, is $40 a reasonable price to charge? When you figure in gas, Uncle Sam, maintenance, repairs, etc - is that around the going rate for 1 acre property? Thanks!
