Our team provides countertop fabrication to your drawings or to our own field templates, delivering careful fits in older kitchens and schedule-driven installs for both residential and commercial projects. On commercial work we return shop drawings for your approval before fabrication, and on a home we template the installed cabinets, never a floor plan.
From reinforcing a light old cabinet base to carry stone to phasing a counter swap around a store's trading hours, our team handles every detail. Serving Ontario, Upland, Fontana and Chino, we ensure fast, efficient service and deliver reliable, professional and beautiful results on every countertop project.
How we work

Countertop replacement in the older Ontario homes near Euclid Avenue starts with the cabinets, because kitchens in that part of the city were built long before stone tops were common and the boxes under them are often too light or too out of level to carry a slab as they stand. Ontario was laid out by the Chaffey brothers in 1882 and incorporated in 1891, and Euclid Avenue, with its wide lanes and grassy median, was the spine of the model town they planned. The streets north of the 60 hold a large share of the city's oldest houses.
A check that the base cabinets are level along the whole run, with shims or new supports where they are not. Reinforcement where an old box was built for laminate and will now carry granite or quartz. A plan for the old top. Tile on a mortar bed is heavy and slow to remove, and the wall behind it usually needs patching. A realistic look at the sink base, since an undermount sink needs a cabinet that can take its weight and its clips.
Granite is a natural stone cut from a single slab you can pick in person, and it needs sealing from time to time to keep stains out. Quartz is engineered from ground quartz and resin, resists discoloration from food, and needs no sealing, which suits a busy family kitchen or a rental. Solid surface is a lighter option whose seams are sanded almost invisible, and it can make sense where a very old cabinet run would need heavy reinforcing for stone. We talk through all three at the template visit, with the cabinets in front of us. This is the part of a replacement that decides whether the new top lasts. The slab itself is the easy half.
Ontario is the main source of hospitality countertop work within reach of Rancho Cucamonga, because Ontario International Airport, the Ontario Convention Center and Toyota Arena bring a steady flow of visitors who need rooms and meals. The airport, established as the Municipal Airport in 1929, is the city's largest employer and ranks eighth in the United States by cargo carried. The convention center opened in 1997, and the 11,000-seat Toyota Arena opened in 2008.
For a hotel, the work is guest bathroom vanity tops repeated by room type, lobby and breakfast bar counters, and back-of-house tops. For a restaurant, it is a bar top, a host stand and a service counter built to the health inspector's expectations for food-contact surfaces. In both cases the buyer is a project manager or a general contractor, and the right first step is to send the drawings and the finish schedule. We price by room type or by counter, return shop drawings for approval, and plan installs around occupied floors and service hours.
Retail and restaurant counters in Ontario turn over when the tenant does, so most of that work is tenant improvement rather than remodeling. Ontario Mills, opened in 1996, is the largest outlet mall in California, and every change of tenant in a center like that can mean a new cash wrap, a new service counter or a new bar. The new tenant's general contractor has a short window between the old lease ending and opening day, and the countertop has to arrive in that window.
That is a schedule problem more than a stone problem. We template the installed casework as soon as it is set, fabricate to the approved drawing, and install on a night or early morning if the center requires it. South of the 60, Ontario Ranch, described by the city as the largest master-planned community in Southern California at 13 square miles, adds new retail centers and builder work of its own, which our builder packages page covers separately.
Countertop costs in Ontario depend on whether the job is a home or a commercial space. For a home, a kitchen replacement is typically estimated at roughly $2,500 to $6,000, and older Euclid Avenue area kitchens sit toward the higher end when the cabinets need work first. Quartz is usually estimated at about $60 to $150 per square foot installed and granite at an estimated $40 to $100 per square foot installed.
Hotel, restaurant and retail work is not priced from a per-foot figure on a web page. A bid is built from a takeoff of the drawings by room type or counter, the material and allowance level, the submittal and shop drawing cycle, the number of mobilizations if the job is phased, any night or weekend work, slab lead time, and who sets sinks and fixtures.
All figures here are estimates for Ontario and are subject to change. The final price is set in a written quote for a home, or confirmed on bid from the plans and the site walk for commercial work.
Ontario sits directly south of Rancho Cucamonga, so our crews reach it without a long haul. Interstate 10 and State Route 60 cross the city east to west, Interstate 15 runs along its eastern side, and Euclid Avenue, which is also State Route 83, runs north to south on the west. A job near the airport, at Ontario Mills or in a Euclid Avenue neighborhood is a short run from our base.
For a homeowner, that means a template visit booked around your schedule and an install date given once the slab is chosen. For a contractor, it means we can make a site walk before the bid and return for templating as soon as the casework is set.
Questions
An Ontario kitchen replacement is typically estimated at roughly $2,500 to $6,000, and older homes near Euclid Avenue land higher in that range when cabinets need levelling or reinforcing before stone goes on. Your written quote sets the final price.
Often yes, after some work. We check level and strength at the template visit and quote any shimming or reinforcement before the slab is ordered.
Yes. The older neighborhoods north of the 60 and the new homes of Ontario Ranch to the south are both a short drive from our base, and both are booked on the same schedule.
