Sidewalks, driveway approaches, footings and foundations, slabs, and curb and gutter across Los Angeles County. Our Class A license lets us work on city sidewalks and streets, not just private property.
Quality Grading & Paving is a licensed concrete contractor in Los Angeles County since 1993 (CSLB #643034). We pour sidewalks, driveway approaches, footings and foundations, slabs, and curb and gutter. Our Class A General Engineering license covers work in the public right-of-way, so we can repair and replace city sidewalks, curb ramps, and driveway approaches under city permit, and we are DIR-registered for public works. Every job is quoted in writing after a free site visit.
We grade and compact the base ourselves before we pour, so the concrete doesn't crack, settle, or lift.
Remove and replace lifted, cracked, or trip-hazard sidewalk in the public right-of-way, under city permit and to the city's standard plans.
New, widened, or replaced driveway approaches and curb cuts, permitted and inspected by the city.
Footings and foundations for ADUs, additions, and new construction, dug, reinforced, and poured to the approved plans.
Slabs on grade, equipment pads, and parking pads on a properly compacted base.
Curb and gutter, rolled curb, valley gutters, and ADA curb ramps for cities, developers, and commercial sites.
Commercial walkways, entries, and flatwork around buildings and parking lots, often paired with our asphalt work.
Sidewalks, curb ramps, and driveway approaches usually sit in the public right-of-way, which belongs to the city. Work there needs a city permit, and cities expect a contractor with the right license classification and insurance to pull it. Many concrete contractors only work on private property.
Our Class A General Engineering license covers public right-of-way concrete. We pull the permit, build to the city's standard plans, and get it inspected and signed off.

Text or email us a photo of the notice and the sidewalk. We'll tell you what the city is asking for and send a written quote.
Send Us the Notice →Most failed concrete fails from below: soft soil, poor compaction, or water running under the edge. We hold grading and paving licenses (C-12 and C-21) and own our equipment, so we prepare the base ourselves before we pour.
Many jobs need both: a new driveway approach and the asphalt behind it, or ADA ramps and walkways along a parking lot. We do the concrete and the asphalt, so there's one contractor, one schedule, and one bid.
Concrete is quoted per job after a free site visit, based on area, thickness, reinforcement, access, and permit requirements.
