We've used Nutri Lawn after a bad experience with another company and they do the job we've agreed upon. We haven't had any huge issues with them and when we did have one small matter about the side boulevard (we're on a corner lot) it was taken care of quickly.
We used Eco- Green services a couple of years ago and we encountered a problem where my son was hospitalized for a very serious medical condition. Both my husband and I missed a lot of work and therefore were extremely short on funds. I cancelled the service with Eco- Green as it was an extra bill we didn't need. That same week someone was sent out and they sprayed the lawn and a bill was left. I tried on several occasions to correct the issue with Eco-Green and then one day I came home to an extra large neon sign on my front door for all the neighbours to see. It said in bold Black letters "COLLECTION NOTICE". With all the issues I had with my son's illness I didn't have the fight in me or I would have sued them. I seriously regret not having done so to this day. So although their weed control service was good I wouldn't recommend them because their customer service and ethics are extremely poor.
