Ace Gallagher Stump Grinding is a full service company with the knowledge, experience and technology to service all of your commercial and residential stump grinding needs. Since 1989 we have been providing top quality services at competitive prices throughout the Metropolitan area.Stump Grinding can be done where grass is to be planted, to make room for a new tree, or to clear the way for a driveway, paving stones, or poured concrete. In all cases the process is virtually the same, though we often need to go deeper when a new tree is to be planted. Stumps are ground to 8-9" below grade. All visible surface roots to the stump are ground to the same depth as the stump. The process turns the stump into mulch. At the end of the process, all of the mulch is raked into the newly-created hole. All walkways and surrounding areas are blown clean as well.
