    Excellent. I would highly recommend this company.  Adalberto is an artist and skilled craftsman as far as granite.  His tile man Juan is just as talented.  Also great people to work with.  I would give more than 5 stars if possible.

    We went to A.G. Natural Stone in March after a previous stone company completely miscut our countertop and it had to be removed again.  When we went to measure our new countertop, the owner, Adalberto, provided an excellent viewing opportunity and was very informative and flexible.  The shaping of the stone at his warehouse was done fine and to our specifications.  But the installation a couple weeks later was mediocre - there are relatively obvious seams where the counter pieces were mitered together.  A previous counter was installed much better in that respect.  Our BIG problem with A.G. Natural Stone, however, was that the counter was not sealed and Adalberto explicitly told us it was (twice).  It soaked up grease like a sponge until we sealed it ourselves a month later, by which time we were quite distraught about our new kitchen.  Imagine how you would feel after spending 10s of thousands of dollars on a new kitchen and being afraid to use it.  Whole sections of the counter were on their way to being ruined within a couple weeks even though we could see no visible grease or other contaminant.  Either he never sealed it or his sealant was so poor that it was more a grease sponge than a grease protector.  When I called and asked about it, Adalberto reiterated that he sealed it and claimed that it was the nature of stone, even sealed, to soak up grease.  THAT fast!?  If grease spots appeared as fast as ours, stone countertops would unusable and they would be in virtually no kitchens in this country.  So, to be blunt, he did not seal it.  His casual response to our concern (which we stupidly believed) left us afraid to use our new kitchen!  The last straw was when a used baggy (with no obvious oil on it or in it) was left on the counter for a mere 15 hours (from dinner until the next morning) and created a stain 6 inches across by the time I noticed it the next morning.

    So we decided another layer of sealant would at least help.  But when we sealed it ourselves, just once, the grease stains stopped!! They did not simply happen less; they STOPPED.  He or his crew never sealed the counter and then failed to double check the error when I reported a problem to him on the phone.  If he had told us up front that his company did not seal stone and it was entirely the customers responsibility, we would have been warned and things would have been very different and I would not be writing this negative review.

    For several weeks I searched all the granite and marble places in the tri valley for a marble remnant that I needed for my hearth.  I learned that those big time companies would not sell me a remnant since there was no installation involved, in other words, I would not be spending enough money there.  I was becoming desperate (and angry) and at a loss as to what to do since my mantel guy was building my mantel and I was on a time constraint.  Finally, I had the absolutely great luck to find AG Natural Stone in Hayward.  When I walked in that place and explained what I needed, the owner took me outside and showed me a wonderful and large selection of granite and marble remnants.  Not only were they for sale, they were happy to sell them, no matter how small the job was!  The owner was professional, and very willing to help me out, listening to what I wanted.  I was able to find a wonderful remnant of Calcutta Marble which would work perfectly for my job.  I selected a bull nose cut that I wanted and within 15 minutes I was done.  The piece was delivered yesterday and I could not be more pleased with the fantastic piece of marble I got and the beautiful job AG Natural Stone did on the bull nosing.  They even finished the job early, and delivered without any problems.  So, for any of you out there that just want a remnant (or if you want to do a whole kitchen or bath, they do it all), these guys are the ones to check out.  I am thrilled with their service, professionalism, very reasonable pricing and expertise, everything about working with these guys made what was a very frustrating  situation just plain go away.  I will use these guys forevermore for all my marble and granite needs without a doubt!  Fantastic!!!
