All-in-One Excavation & Grading
While most contractors subcontract excavation and grading to multiple companies, Westward Builders does it all. To us, it doesn’t make sense to have one company mobilize equipment for site grading only to bring in another to handle footing and utility trenching with the same type of machinery.
By managing both processes in-house, we offer:
- All-in-one efficiency – We handle grading and excavation for footings, utilities, and site preparation
- Significant cost savings – Needing only one contractor means fewer delays and lower expenses
- Well-maintained fleet – Our equipment is serviced regularly, reducing unexpected issues and keeping projects on schedule
- Clean, efficient operation – All equipment is registered with the California Air Resources Board, ensuring compliance and environmentally responsible fuel use
The Projects We Can Handle
Our expertise in excavation and grading extends across a wide variety of projects, including:
- Residential construction – Preparing lots, grading driveways, and trenching for utilities and foundations
- Commercial sites – Excavating and grading large properties with efficiency and precision
- Limited-access projects – Managing challenging terrain, such as hillsides, with specialized equipment and techniques
- Retaining wall preparation – Excavating and grading for structural walls that protect against erosion

Whether your project is straightforward or complex, our team has the knowledge and equipment to deliver lasting results.
