I bought a house in a Reston HOA with strict requirements that i fix the cracked and sunken concrete slabs in front stoop. The first problem was - the concrete is a pinkish yellowish color, and I didn't want to have to replace it with ugly grey as it would not match the other concrete in the front yard. The second problem is, no one would do the work. Except Mark of A-1. He asked for photos - I sent them, and agreed to do the work for what I thought was a fairly large chunk of money for, what I thought was, a small job - $2000. However, having little choice, and being excited by the fact that he said he could keep the original concrete (and color, remember - pretty, pretty pinkish yellowish concrete), I said yes. Remember, I don't know anything about what masons charge for fancy concrete work. He kept in contact, emailed/phone me regularly to tell me why the weather was delaying our install date. But the day came, and I came home to find.... a miracle. He did an incredible job, he lifted the concrete slabs, filled underneath them, put an under concrete drain to divert the water from my gutters, prettied it all up, put down a sealant on the cracks, and put down pebbles to pretty it all up. It looks brand new. Worth every penny. HIGHLY recommend. read more
