Serving Brentwood, CA and surrounding areas. (916) 618-0802
Every driveway or paving project starts with the ground beneath it. Our Brentwood crew grades to the right slope, excavates to a solid depth, and builds a base that holds up through Brentwood summers and wet winters.
Grading and excavation in Brentwood, CA means reshaping and leveling the ground to the correct slope and depth before any asphalt is placed - for a standard residential driveway, the work typically takes one to two days from equipment arriving to base ready for paving.
No asphalt surface is stronger than the ground beneath it. In Brentwood, where the clay-heavy soils swell in winter and shrink in summer, this step is especially critical. A surface that looks level in spring can show soft spots and low areas by fall if the base was not excavated deep enough and compacted properly. For new driveways and paving projects, grading and excavation is not prep work you skip - it is the foundation that determines whether everything above it holds up. It also works closely with drainage solutions to make sure water moves away from your home, not toward it.
The slope built into a graded surface is not cosmetic. Water sitting on or under pavement is the primary reason driveways fail early in this area, and a properly graded surface moves water away cleanly after every rain.
Standing water on your driveway or along its edges after winter rain is almost always a grading problem. The slope is either too flat or running the wrong direction. This will get worse over time as water works its way under the base and softens the ground below.
Visible low spots or sections that feel soft underfoot are signs that the ground beneath has shifted. In Brentwood's clay soils, this kind of movement is common as the ground swells and shrinks through wet and dry seasons. Regrading and recompacting is the correct fix before new asphalt goes down.
Any new paved surface needs proper grading before asphalt can be laid. If you are adding a second car pad, widening your driveway, or starting a new surface from scratch, grading and excavation is the required first step - not optional groundwork.
When water consistently runs toward your home rather than away from it, the grading around your driveway and approach is working against you. Correcting the slope is often the most direct way to stop water from reaching your foundation - and far less expensive than foundation repair.
We handle grading and excavation for residential driveways, lot prep, and commercial paving projects throughout Brentwood and the surrounding area. Every project starts with a site walk so we can assess the existing slope, soil conditions, and drainage before a single piece of equipment arrives. We pull any required permits and coordinate utility locates before digging - in California, that means calling 811 to have underground lines marked before any excavation begins.
After excavation, we install a compacted aggregate base layer that is the real structural foundation for your asphalt. Base depth and compaction quality are what we specify in writing on every job - those details determine whether your finished driveway stays flat and firm or develops soft spots within a few seasons. For projects where drainage slope and concrete curbing and sidewalks need to work together, we can scope the full project in a single visit.
Best for homeowners starting a new driveway or expanding an existing surface that needs a proper foundation from the ground up.
Suited to existing driveways where water is pooling or running the wrong direction and the slope needs correcting.
For projects where the existing base has shifted or was never adequate - excavate, recompact, and build it right before paving.
For property managers and developers who need grading and excavation completed to spec before a paving crew takes over.
Brentwood sits in the eastern Contra Costa County area where clay-heavy soils are the norm. These soils swell when wet and shrink when dry, which means a graded surface that looks perfect in spring can shift noticeably by late summer. A contractor who knows this area builds that movement into the grading plan from the start - setting grades and compacting base layers in a way that accounts for what the soil will do through the seasons. For homes in Brentwood, most of which were built in the early 2000s on subdivided lots with moderate-sized yards, drainage slope is often the detail that determines whether a driveway and foundation stay dry through the winter rainy season.
Brentwood has grown rapidly, and the city's permitting and public works processes are active. Work near the curb cut or within the public right-of-way often requires separate city approval in addition to a standard grading permit. We are familiar with local requirements and handle permit coordination as part of every job. We also serve neighboring Antioch, where similar soil conditions and drainage demands make proper grading just as important.
Describe what you need - new driveway, regrading, full excavation, or lot prep. We respond within 1 business day and schedule a site visit to walk the property before quoting. Grading work cannot be accurately priced from a photo alone.
We assess the existing slope, soil, and drainage on your property and identify any permit requirements for your specific address in Brentwood. You get a written scope that specifies excavation depth, base material and thickness, and finished slope.
Equipment arrives, removes existing material to the required depth, and shapes the ground to the correct slope. We then install and compact the aggregate base layer in passes - not dumped and left loose. Expect noise and some dust during this phase.
If a permit required an inspection, the inspector confirms the grading meets local standards before asphalt is placed. We walk you through what was done and what comes next so you know exactly where the project stands.

(916) 618-0802We have worked extensively across eastern Contra Costa County and understand how the clay-heavy soils here behave through wet winters and dry summers. That local knowledge shapes how we set grades and specify base depth on every project.
We hold a current California state contractor license - verifiable through the Contractors State License Board online. Grading and excavation work in California requires a licensed contractor, and that license gives you protection if anything goes wrong on your property.
Every scope of work we write specifies the excavation depth, base material type and thickness, and finished drainage slope. Those are the measurable details that determine whether a driveway holds up - and you should have them in writing before a single machine starts.
Before any excavation begins, we coordinate underground utility marking through 811. It is a standard safety step that protects your home, your neighbors, and our crew - and one that a professional contractor handles without being asked.
Grading and excavation done right is invisible when it is finished - your driveway drains, stays level, and does not develop soft spots. That is the standard we build to on every project in Brentwood.
Call 811 before any excavation project at call811.com. Verify contractor licenses through the California Contractors State License Board.
After grading is complete, concrete curbing and sidewalks define the edges of your paved area and help manage surface water at the perimeter.
