The calendar out here really does have two halves, and this outfit works both of them. From the first green flush in March through the last leaf in November, Precision Lawn Care & Landscaping is mowing, edging, trimming, mulching beds and running cleanups. Then the gear changes and the same drives get plowed, the same walks shoveled, the same low spots salted before they set up overnight. Knowing a property in July — where it drains, how the pitch runs — makes it far easier to clear in January. Centreville and the surrounding Metro East towns are covered on both sides of the year.
