I read an article in one of the trade magazines about hydroseeding. It said that the market for this service is wide open! However, a lot of trial and error happens trying to get the right mixtures. But once you've got that figured out, in comes the money.
Wow talked with some companys around here and they get .080 for up to 20,000sqft and .070 for 20,000 to 30,000sqft and .060 for all above 30,000sqft. We also talked with a friend upstate that does it he gets .070 for up to 25,000sqft and .060 for 25k and up with his cost averaging .018 so I think we will go with his prices at .070 and .060 or .065 and .055 for 3 local town gave alot of interest when I told them our company was going to be hydroseeding.
Take a look at http://www.lawnandlandscape.com bulletin board, general interest section. Same question and many good response. Don't worry to much about going rate. Figure out what you need to charge in order to recover your expenses then add profit. As much profit as the market will bear.
Here in MA I charge 6 cents a foot, with a discount over 20,000 SF. Road jobs are less. I wouldn't believe the guys that say they get 12 cents a foot. People are very price sensitive to hydroseeding around here, but a lot of people are doing it as well...
