The work went very well. The crew arrived on time and worked steadily thru the day, and were very good about not letting the water etc get outside the right areas -- and they were working in an area adjacent to hardwood floors thru 3 different doorways, and carpet thru 1. It took a fair amount of doing to get the foyer back to 'shiny' again - but they did it, it turned out great, and was definitely easier to live with than 'remove and replace', which another contractor told us would involve tons of dust and lots of time, due to the marble being set in mud. The large buffing machine they used did hit and mark up the baseboards a few times (the shoe moulding actually), but i don't think anyone could avoid that - it is just the nature of the beast. There was a small place in 1 corner of the foyer that didn't get done as shiny, possibly because they needed to do that by hand when the large buffer and the small hand hand buffer also couldn't fit in there... I mentioned these items to the sales rep after the job, when he asked for feedback, but he didn't respond with any offers to make it all 'perfect',. Ok, so not an 'A++', but still an 'A' rating here from me though, as they did do a very good job, right on schedule. ------UPDATE A Rose tech came back & spent several hours working the areas around the edges that weren't so shiny -- so the foyer marble looks great throughout now, and there are no dull spots in corners etc to catch your eye... overall, really terrific! A great alternative to 'remove & replace'!
