Our Process


Great Rock quotes your project based on your initial selection of stone material, your drawings, or a visit to your home or job site, along with other project requirements.

The following information is required for all stone countertop estimates:

Layout drawing of countertop surface, or visit to your home/job site
Edge profile selection
Sink and fixture specifications
Any custom requirements


Once a material is selected and our project estimate is accepted, we will visit your home or job site and will create a project template, which we bring back to our facility and use to cut the stone.

We ask that the designer, homeowner, or builder make the sink and fixtures available for us to take back to our facility so that we can ensure a perfect fit


The template is taken back to our facility, laid on the slab and traced. A laser-sighted bridge saw cuts along the outline. The saw is equipped with a diamond blade that is water cooled to prevent the granite from chipping or cracking.

A stone worker uses handheld grinding and polishing tools to complete the countertop by finishing the edges to the configuration you have selected.

Depending on scheduling, it takes between 7 and 10 business days to fabricate the counter top after the template has been made.


Bringing a piece of granite counter top into a house is no easy feat, since a typical slab weighs between 200 and 600 pounds. We have even dealt with slabs of up to 1,000 pounds!

Once the slabs are in place, it takes a team of skilled craftsmen to do the final trimming and fitting. The sink is mounted underneath the new countertop and is permanently attached. Then the backsplash is slipped into place, caulked and sealed.

What began as a massive slab in the yard has now been transformed by our Art of Stone crafting into a stunning countertop, expertly installed in your home.
