In my town there is one other irrigation company. He is going to be cheaper in most cases. Here are some of the examples why. He does not believe in head to head spacing. An example how he does things: in a 20' x 60' area he may use 2 rotors choked down vs. my 8-6" MP Rotators. I have seen him spray over a 5' walkway to avoid separate zones. Needless to say he can give a cheaper quote. I try to explain to customers such things in my quote but the average customer will not understand and will just look at the price. One thing I will mention is they might want to talk to a current customer of mine who has dealt with the other contractor and their experiences with them. But the reality is he is going to get most of the jobs in my area. In my state there is no regulation of irrigation so anything goes. Sad but true.
