It was wonderful working with Walko Excavating! Mike Walko couldn't have been any nicer.....he really helped me in designing my yard, from laying everything out to helping pick what type of blocks to use on my retaining wall. He covered everything....colors, durability, price comparison-he discussed all available options and ideas with me. He not only was helpful but had great prices and was very personable and reliable. I would recommend him to everyone! Thanks Mike!
