Demolition & Concrete Cutting in Ontario, CA

Ontario sits at the crossroads of I-10, I-15 and SR-60, next to Ontario International Airport, and it has one of the largest concentrations of warehouses and distribution centers in Southern California. That makes it one of the busiest markets in the Inland Empire for slab cutting, trenching and tenant-improvement demolition.

Demolition Specialist Inc. (DSI) serves Ontario general contractors, developers and facility owners from our Riverside yard. Our own crews, saws, breakers, Super 10 dump trucks and roll-off bins cover the scope from the first cut to the last load, so there is one sub to schedule instead of three.

Building demolition: commercial, industrial and residential structures taken down to the slab, with foundation removal when needed.

Site demolition: slab, foundation and pavement removal to clear the site for new construction.

Concrete breaking and removal: hydraulic breakers and jackhammers for slabs, footings, walls and flatwork.

Flat sawing: diamond-blade slab cutting for trenches, openings, joints and removal.

Wall sawing: track-mounted cuts for door, window and service openings in concrete walls.

Core drilling: clean round penetrations for plumbing, electrical, HVAC and anchors.

GPR scanning: locating rebar, post-tension cable and conduit before cutting or coring.

Asphalt grinding: milling and removal for parking lots, roads and driveways.

Demolition labor: strip-out, debris loading and cleanup crews.

Super 10 hauling: dump truck haul-off for concrete, asphalt and soil.

Roll-off bins: debris bins delivered to the job and hauled off when full.

Every job can be quoted as a fixed-price contract or hourly, and DSI is DIR-registered for public works.

Most demolition in Ontario needs a demolition permit from the city's building and safety department, and buildings in the South Coast Air Quality Management District generally need an asbestos survey and SCAQMD Rule 1403 notification before work starts. Utilities should be disconnected and marked (call 811), and anything to be cut or cored should be scanned when rebar, post-tension cable or conduit locations are unknown.

We work from your permit set and coordinate sequencing with your GC, abatement contractor and inspectors, so the demolition and concrete work lands where it belongs in the schedule.

Ontario is about 20 miles northwest of our Riverside yard via SR-60 and I-15, or I-10 from the north side of the city, so crews and equipment typically arrive early in the shift and can return for multi-day or phased work. Call (951) 737-2077 or send your scope and plans for an estimate; our estimating team responds within one business day.
