A-1 Advantage Asphalt and Concrete

A-1 Advantage Asphalt and Concrete, formerly trading as A1 Advantage Asphalt, is a commercial paving and concrete contractor based in Sacramento and working across Northern California, including the Bay Area and the Central Valley. The company's focus is squarely commercial rather than residential, and its service range is built around the full lifecycle of a paved commercial site rather than paving alone.

New pavement construction and site development sit at one end of that range, covering excavation and groundwork through to a finished surface, along with utility installation. Asphalt repair and maintenance addresses pavement already in service, and the company describes an approach of assessing pavement condition first and prioritising repairs, rather than treating every defect at once. Pavement preservation is offered as its own category, together with sealcoating and crack sealing — the treatments that extend the life of a surface before it needs structural work.

ADA compliance is a distinct specialty and one of the more substantive parts of the offering. The company performs ADA retrofit work including accessible ramps and handrail installation, which is the kind of work a commercial property owner typically confronts after an accessibility audit or a complaint. Because it also handles concrete flatwork, the company can address the concrete trip hazards and non-compliant path-of-travel elements that usually accompany an ADA issue.

The smaller components of a parking lot are covered in-house as well: striping and signage, speed bumps, wheel stops, bollard installation and saw cutting. That range means a lot can be resurfaced, restriped, made compliant and fitted out without a second contractor for the ancillary items.

Customers span commercial properties, retail shopping centers, industrial parks, homeowners associations, institutional sites including schools and hospitals, and municipal agencies. Featured work includes projects for Trader Joe's and Macy's locations in Northern California.

The company also publishes reference material on its site covering asphalt overlay costs in Northern California and commercial parking lot paving standards in the state, and provides estimates for work ranging from striping through to major structural repairs.
