Lawn Care Maintenance and Mowing
I put an inquiry through Angi's List and this company contacted me on May 12. I asked whether they were too busy because I needed lawn service ASAP and I knew I was late to find someone so late in the season. I was assured they could come that same week. After multiple calls and emails, I was repeatedly given dates they would arrive, but they did not show up when promised and ultimately came about a week later. I knew the long weekend was coming up. While working in my backyard, a worker broke my patio door glass. He apologized and assured me the company would repair it. I was told the owner would measure and replace the glass. I was also told they would return the following week to continue the lawn work. Since then, they have not returned, nor replaced the broken glass of the patio door, and have not responded to my emails or voicemail messages. I am left with a damaged patio door, unfinished lawn work, and no communication. Very disappointing experience and poor follow-through.

The whole team started to work immediately. They did Wonderful Job. They did my large backyard, and a Small trail on the side of my side, they also did the front yard. They filled up a lot Black Bags. The whole team did a Great Job!!!!! It's too bad, that they didn't put up the weeds all over. Thank you very much for recommending this team to me. I want them to come back in 2 weeks, NOT 1 week Thank you very much for your Help and Support. June Messina Jmlovesdogs623@gmail.com

Men show up regularly to mow lawn; however, I have been trying to contact Dom to have shrubs cut and manicured but he NEVER returns a call. I will not use this service again in the future. Barbara G

We had a biweekly agreement for property maintenance and my property has not been maintained since the end of September 2020, and they have us on an auto bill for service not performed. Then they had the never to bill me for claiming to have fixed my sprinkler system and it hasnt worked since they touched it. Had no problems prior to visit. Was just suppose to be a simple system turn on. and they claimed they had to do maintenance before turning it on. There are leaves all over the property still sitting there since September. Then it snowed and we heard nothing from then. I would never refer this company and I have already reported them to home advisor. They never answer the phones, never return messages and never reply to emails. Had got 1 call a month ago saying they would make it right and no one showed up. TERRIBLE SERVICE!!!!
