"Leo and helper rebuilt outdoor stairs and did a very nice job. He was quick and professional from first contact to job completion. But, he underestimated wood needed for replacement of deck boards and he didn’t bid the cleanup/disposal of removed wood so the quote was short by $300. I would recommend Leo just be sure the quote includes everything you want done."
