I reused granite in my last kitchen and it worked out really well. However, I was told over and over again that it couldn't be done. Some places gave no reason, others said it would surely break when it was removed. After watching the process from start to finish (including trip to the shop), I don't think it's that challenging and I suspect everyone I phoned just wanted to scare me into buying new.

We had an enormous 96"x48" island, also in black granite. Really stunning, however I couldn't live with the cabinets and a few other design details in the kitchen. We were on a really tight budget so we wanted to take the entire kitchen apart carefully and reuse as much as we could. I was also told I couldn't do this with the cabinets, though this also was no problem and quite fun to puzzle the old and new all back together. Anyhow, when it came to reusing the granite island, I decided to move the sink so couldn't reuse it as is. Instead, I had it removed and taken to a shop where they cut it into a 96 x 18" piece which became a raised bar along one side of the new island (which was done in cherry butcher block) as well as a new counter with sink for in the pantry. It all turned out beautifully. We also re-used other pieces of granite counter but they stayed attached to their base cabinets so didn't have to leave the house.

I think it's a shame to waste anything that is reusable but there are lots of options if you don't want to use it yourself - sell it or give it away on Craigslist/kijiji or Habitat For Humanity. We gave away all our cabinet doors in our last house and this time around HFH will be coming to do the removal/salvage for free in exchange for everything they can take away.

Usually the granite is glued to plywood that has been nailed down to the top of the cabinet. A lot of granite can be removed and reused but it is not a sure thing. The skinny bits around the sink and stove top are likely to break.

maybe you don't need to pull all the cabinets?

You have damaged cabinet bottoms. How about posting pics of all the damage. We may come up with options worth considering.

Like jesslake I have also reused granite. In each case, I purchased used granite from Craig's List, we removed the granite ourselves, and moved it to the new location and installed it. One piece was an island top, the other granite were the perimeter counter tops. I designed the kitchen to fit the granite, we cut the granite where we needed to with a diamond blade on our circular saw, and it came out great. It can be done. There is a risk, but we were careful and had not breakage.

I see salvaged countertops all the time at the habitat restore store . So yes it can be done .

I had cabinet bottoms replaced.

I've recycled a few granite jobs. It can be done cost effectively, but don't panic when something breaks; it's nearly inevitable but granite repairs well.

When I was redoing the kitchen in my remodel, I bought a complete kitchen at a demo sale. We were able to remove, transport and reuse the granite without breaking anything. We estimate the largest piece weighed close to 400 pounds with smaller pieces weighing in around 200 pounds. Figure about 40 pounds per linear foot and you won't be too wrong.

It took two strong construction guys to get the breakfast bar countertop from the cabinet top to sitting upright on the floor. These guys have lots of construction experience and have worked on a professional moving crew so they understand how to move heavy items. It was a tricky endeavor without the specialized granite handling equipment and not something I would recommend to average homeowners.

If I was to do that again, I would certainly be asking the guy who did the recutting if he would be willing to remove the granite from its original location and transport it to my new project. I don't think anyone could convince me to be involved with moving another 400 pound piece of granite, especially with stairs involved. We can handle ordinary countertops but not interested in repeating our adventure.

When we demo'd our old kitchen, my BIL hauled the granite and the cabinets 250 miles in his pickup truck, and reinstalled the whole thing (Kohler cast iron sink still attached) in my sister's canning kitchen. Nary a scratch. Good luck!
