Proposals are based on cabinet drawings or a rough sketch provided by the customer (see sample drawing)


Alterations/changes on the original plan can happen once construction has begun.

Wooden templates will confirm final pricing.



A template for cutting (final measurement) is made once the job site is ready.



Base Cabinets should be installed and secured to the wall.  Upper cabinets need to be installed if full backsplash is needed.  Doors, drawers, side panels in place.  Anything that relates to the granite must be in place or on site: stove, microwave, garden windows, sills, upper and lower bars.

Cabinets must be level with 5/8” plywood sub-top.

Sistone Inc. is not responsible for unleveled cabinets.

Topmount sinks and cook tops must be at the job site.

Undermount sinks, cast iron and stainless steel are to be countersunk flush or 1/16” below top surface of plywood sub-top. (sink can be plumbed for use but must be removed (1) one day prior to stone installation)  Save paper or cardboard templates that come with the sink for installers to use.

Some situations may require that we take the sink to the shop.

Regular Undermount Sink requires a rectangular cutout and exposed edges to be polished. Faucets may be installed directly into the sink or into the countertop.

Irregular Undermount Sinks are when the sink opening in the stone is irregular in shape and the faucets are mounted on top of the stone.  If client prefers this option, he must select a true undercounter sink with holes approximately 3” in diameter so plumber can fasten fixtures to the bottom of the stone. Also, separate sink bowls with no holes fall into this category.

Backsplash – If backsplash is to be another material, we need to know thickness of material and method of installation, i.e. mastic or modest.

Client and / or Project Manager must be present for templating. Any questions, changes or interpretations of the contract can then be discussed.  Template technician does not discuss prices or course of action.  Client should call salesperson for any changes.

Seam location is determined by the shop based on size of slabs, location of sink and/or cook top, safety and prevention of breakage during transporting and installing.

Changes made after template will require additional charges for retemplating, redrawing, and/or refabrication.  Better to delay the template until everything is ready than to cause extra expense and waste time.

Appliance garages and cabinets that sit on top of the stone must be installed after stone has been installed.



The fabrication time for custom counters is usually 7 to 10 working days from the time the template was taken, color was selected, final proposal signed, material at shop and deposit received.


Installation is approximately 1 to 2 full days.

Before the installers arrive, please check the following:

Cooktops, ranges, downdrafts, hoods, topset sinks or anything else that requires cutting of the stone must be at the job site.

Sink plumbing and garbage disposals must be disconnected / removed (the installers will need to move the new sink into position).

Faucets must also be removed if they have been installed.

Sistone installers do not do plumbing of any kind.

Stone counters are very large and heavy.  There needs to be a clear and easy path free from clutter.

The installer will need access to electricity and water.  We will be doing some detailing at your job site.  Yes, there will be some dust.

Please do not have any other trades working in the area.

Cooktops need to be disconnected.  Ranges and refrigerators may have to slide out if the space is too tight.

Concerning mirrors, Sistone recommends that you remove wall-mounted mirrors and glass shelves.  Should you elect to leave these items on the walls during the demolition and installation process, Sistone will not assume any liability for damage and replacement costs.



Almost, the sink caulking and grout also need to cure.  You will compromise the seal of the caulking, if it is not allowed to cure for 24 hours.

Schedule your plumber and other activities after the drying time.
