I don't know if this is the right forum or not, but I'll try it. I currently do mowing and some small landscape, but I'm looking into expansion markets. My idea is to start trenching and laying drain tile for drainage problem areas. This is a common problem that I see while mowing, but I don't see much advertisement for solving the problem. My question is in regards to insurance on something like this. For GL insurance on a mowing only service the premium is fairly low. What are the premiums like when delving into something like this? Thanks for any feedback.
