I'm fairly new to the whole thatching process and did a few last year with pretty good results. I had a potential new customer ask for a bid for dethatching his yard and was hoping for some input on pricing this. The yard is pretty good size, around 19k sq. ft. but very open. I remember doing some 4-6k lawns last year and having a huge amount of thatch to clean up and get rid of. I don't mind doing the work but when I gave him a price he nearly freaked. I have been pricing dethatching jobs about 1/3 higher than aerating costs. So I'm at about $24 per 1k sq.ft. This seems to leave me some room for profits after renting the machine and breaking my back cleaning it up, plus the dump fees. Is this reasonable or am I way too high?
