Incredibly impressed with Greenstone Gardens, Mark Howarth, Mark Jr., and their talented crew. From start to finish, the entire process was professional and expertly managed, and completely met and exceed our expectations. They have a true passion for their craftsmanship, which showed in their design, selection of plant materials, installation of materials (retaining wall, patio pavers, sod, mulch, plants, fencing, and lighting), and work ethic (timely arrival, 6 work days/week, daily clean up, and courteous manner). Our backyard landscaping project (major regrading surrounded by a 3-sided retainer wall - up to 4 feet at its highest point; 23x18 large patio with steps; walkway; drainage pit, and ambient lighting on a timer, to name a few features) was completed in the estimated 3 weeks. Our neighbors were just as impressed, and jokingly referred to our backyard as the best in Delaware County!
