Concrete Curbs, Gutters & ADA Ramps for Commercial Properties
Curbs and gutters do more work than most property owners realize — they control where water goes, protect landscaping and building foundations from runoff, and define traffic flow through a parking lot. A&L Asphalt installs and repairs concrete curbs, gutters, and ADA ramps for commercial properties throughout Sonoma and Marin County.
Why Curbs and Gutters Matter for Commercial Properties
Without properly built curbs and gutters, water runs unpredictably across a parking lot or property, which accelerates asphalt damage, creates standing water problems, and can direct runoff toward building foundations or landscaping where it causes real damage over time. Curbs also define parking boundaries, protect building exteriors from vehicle contact, and create clear pedestrian pathways separate from vehicle traffic.

Signs You Need Curb and Gutter Repair
Look for cracked or crumbling curb sections, water pooling in areas that should be draining, settled or uneven sections creating trip hazards, or curbs that no longer effectively direct water away from your building. Left unaddressed, drainage problems tend to get worse and more expensive to fix over time.
Curbs, Gutters, and ADA Compliance
Curb ramps are a required part of an ADA-compliant accessible route, connecting parking areas to building entrances. If you're addressing curb and gutter work, it's often the right time to also confirm your ramps meet current ADA requirements — we can evaluate both at once and handle any needed truncated dome installation as part of the same project. For striping and accessible parking space compliance specifically, see our dedicated ADA compliance service.
What Affects the Cost of Curb and Gutter Work
Cost depends on the linear footage of curb and gutter needed, drainage complexity, and whether ADA ramp work is included. Repair of existing curb sections generally costs less than new installation across a full property. We provide detailed written estimates so property managers can budget accurately.
Why Property Managers Choose A&L Asphalt
We handle curb, gutter, and ADA ramp work as part of full commercial paving projects or as standalone jobs, which means we understand how drainage, paving, and accessibility requirements all connect on a real property — not just one piece in isolation. That's the difference between a curb that looks fine on installation day and one that's still directing water correctly five years later. Contractor License #801317.
