Aeration requires preparation work on your part, such as marking irrigation systems and watering the lawn, so you must know when your service is happening. At Blades of Green, we pre-notify you during critical times so you can adequately prepare for your service.
It is worrisome if a company says they will not notify you or offers a very large window of time when they would service your lawn. It could mean many things, including that their experience is limited or they may be short-staffed, but mostly that they do not have an established system to care for their customers properly.
