Lawn Care Maintenance and Mowing
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.

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!!!!
