"Grady with Keystone made my job a priority. He had a busy schedule the upcoming weekend, but I really wanted a junk pile removed asap. He showed up at 10pm (with permission from myself and neighbors) and got the job done quickly (and quietly for that time of night!) He is reliable and trustworthy!"

"Fair price, great work, quick turnaround time. Grady at Keystone did a couple different projects for me prior to moving into our house, full brush clearing, cleaning out of mulch beds, landscape paper, new mulch, edging, stone, tree trimming, haul away, mowing and weed eating. All my new neighbors were very excited with the results as are we."
