Granite countertops in Downtown Ontario, the historic core
Downtown Ontario is the city's historic center, with older homes, apartments and storefronts near Euclid Avenue. Usually, many kitchens here have original layouts. So careful templating makes a big difference.
First, we measure on-site. Next, you pick the slab yourself. After that, we cut it in our shop and install it, with no subcontractor involved.

Downtown Ontario kitchens and apartments
Older homes downtown often have cabinets that are slightly out of square. Therefore, we template every wall and level the stone at install.
Apartment owners also call us for unit updates. For example, one quartz color across all units looks clean and simplifies repairs. Also, we can schedule several units together.
