ISC Granite Factory

ISC Granite Factory is a Chino, California countertop fabricator with a 3.6-star rating from 14 reviewers, operating as a factory-direct source for granite and stone countertops. Their factory model sets them apart from pure installation companies because the stone is cut and finished on-site before it ever reaches your home. Chino sits in a well-connected part of the Inland Empire, close to both Chino Hills and the Ontario area, where residential remodeling has been active for years. They also carry kitchen supplies and cabinetry, making them a broader resource for renovation projects.

ISC Granite Factory handles the complete countertop workflow: template and measurement, custom stone cutting, edge profiling, sink cutouts, and final installation. Their kitchen supplies category suggests they carry materials, fixtures, or accessories beyond just stone slabs, which can simplify sourcing for a remodel. Edge profiles are selected during the planning phase, with options ranging from simple straight edges to decorative ogee or dupont styles. Bathroom vanity tops are also fabricated with the same precision process used for kitchen surfaces.

A factory-direct granite operation in Chino means customers are working closer to the source, which can reduce markup compared to going through a separate showroom and fabricator. Their cabinetry offering rounds out the kitchen renovation picture, giving homeowners and contractors a single location to coordinate stonework and cabinet selection. The factory setting also allows for more direct quality control over how each slab is cut and finished.

You start by visiting or calling to discuss your project, view slab options if you're selecting material, and get a free estimate. The team then schedules a template visit to your home to take precise measurements of your layout. Back at the Chino factory, your slab is cut and finished to those exact specs before being transported to your home for installation. The full timeline from estimate to installed countertop is typically two to three weeks for most residential projects.

ISC Granite Factory serves Chino and the surrounding Inland Empire communities, including Chino Hills, Ontario, Montclair, Pomona, and Diamond Bar. Their factory location in Chino is centrally positioned for customers in both western San Bernardino County and eastern Los Angeles County. Contractors and homeowners throughout the area regularly source granite and countertop services from Chino-based fabricators.
