I noticed a gap between my granite counter top and my under-mount cast iron sink and was concerned about it breaking loose and damaging the counter top above or the plumbing below. I called around to a couple different places and Lionel was the only one who was able to make it over the same day. Everybody else had openings later on next week. He was onsite within an hour and had it fixed within 20 minutes. I'm glad I called and recommend his services.
