Very GoodAbout INSTONE Marble
In 1998, Paul Charondo founded the business. Paul has been employed in the stone sector since the early 1990s, and throughout that time he has observed the demand from suppliers for manufacturers to lift the bar on a range of styles and methods. In order to reinvent the countertop installation service, he founded his own company. Over the next 20 years, he became well-known as the Bay Area's top countertop fabricator. Custom-made granite and marble countertops are fabricated and installed by them. The prices are determined by the purchased square footage of the material rather than the size of the complete slab. This makes sure you only pay for the countertop you actually need. The finished product is sent to your doorstep after internal manufacture.

We hired Almaden Kitchen and Bath to provide and install granite tops on a bar top and three large bathroom vanity tops. The experience was fantastic! Terry, the owner is a pleasure to work with. She is professional, efficient and accurate. The pricing was reasonable and the installation of the highest quality. In addition, although Almaden Kitchen and Bath is located in San Jose, Terry and her team were happy to travel to Walnut Creek to perform the work. I would highly recommend Almaden Kitchen and Bath.

The least stressful part of my home renovation was getting new countertops throughout my house. These guy were super patient, very accommodating, professional, and speedy! They were able to do a pop up outlet in our granite that several other fabricators refused to do. They even agreed to come out twice so that I could have a counter on my island before my other cabinets were ready for a counter. Cannot give a high enough recommendation!!

Went there last week to order Corian slab for my Yacht Galley. Janet was very helpful and nice. I had done a lot of shopping and her pricing is very competitive. Its the reviews that got me in their door. There aren't any installers that I can find in the Kemah area and Im pretty handy at making/building stuff. My wife being a degreed interior designer of course wants to start changing everything. All is well with that because "Happy wife is a Happy Life" Right???lol. It was I who wanted the Yacht, and her "buy in" is to having everything a "designer space". All that being said, I am extremely nervous because of the "0" tolerances on yacht builds. Similar to aircraft. Janet assured me her craftsmen could do it. They are actually build it then I will install it. Lordy, Lordy I'm NERVOUS!! I just ripped out the countertops of a perfectly good yacht!!! Its going to have to be perfect and exact in so many areas............
