I saw ads for core-aeration last year for $60.00-$65.00 any size yard. Last year I charged a minimum of $65.00 for a small yard and price went up with size. Most of my yards are under 1/4 acre. Even at $65.00 - $75.00, some people growl at the price. Anyway, I was looking on the Rental Works website for Richmond and the cost to rent an aerator for 4 hours is $86.03 including taxes and insurance. This price is for customer pickup and return of the aerator. The total price if you want Rental Works to deliver and pickup is $161.03. The point is, I could make more money renting my aerator than taking it to the customers house and doing all the labor. There would also be more money in delivering and picking up aerators. I've even heard of people doing aeration for $40.00 or $50.00. Shouldn't the minimum for aeration be at least what it would cost to rent an aerator plus labor? It seems that I and maybe others are not charging enough for this service. I make out pretty good if I have several yards together on the same day, but that doesn't happen all the time. I think I'll try to go up on price this season. Aeration is too back breaking to do for less than rental rates.
