Our Services
From aggregate hauling and construction material hauling to demolition debris hauling and removal, demo haul-off, and jobsite material transport, KG Contracting handles the logistics so your crew can stay focused on the work in front of them.
Whether you need a straightforward gravel driveway installation, a more detailed hardscape driveway design, or full driveway construction on a new build, KG Contracting delivers a driveway built to handle Northern Arizona terrain and weather.
From utility excavation and site grading to land grading and full excavation and site preparation, KG Contracting handles the groundwork that determines how well the rest of a project performs.
Every landscaping and hardscaping project starts with an assessment of soil, drainage, and grade so the finished result performs well for years, not just at installation.
Concrete flatwork and slabs depend heavily on proper site preparation, and KG Contracting manages that groundwork alongside the pour so the finished slab performs correctly from day one.

Why Site Work Requires Local Experience
Not every excavation contractor understands what it takes to work in Williams, Flagstaff and the Northern Arizona specifically. The combination of high elevation, volcanic rock, and dramatic seasonal weather swings means that grading, septic, and clearing decisions that work elsewhere don't always translate directly to this region. A drain field designed without accounting for local percolation rates can fail.
A gravel driveway installed without the right base can wash out during monsoon season. A building pad graded without considering snowmelt can direct water straight toward a foundation instead of away from it. KG Contracting's approach to every project starts with understanding these local conditions before any equipment moves onto a site. That means a percolation test before septic design begins, a soil and rock assessment before excavation timelines are set, and a drainage plan that accounts for both summer storms and winter snow. This attention to regional detail is what separates site work that holds up for decades from work that needs to be redone within a few years.
Whether the project is a single residential lot or a multi-building commercial development, the underlying principle stays the same: the quality of everything built afterward depends on the quality of the site preparation that comes first.
Excavation Services – Major Grading or Resloping
Major grading reshapes land to a specific elevation, while resloping adjusts existing slopes to improve drainage and stability. KG Contracting handles both for residential and rural properties, correcting drainage issues, preparing building pads, and stabilizing slopes that have started to erode or shift.
Septic System Installation and Replacement
Properties without access to municipal sewer lines rely on a properly designed septic system to manage wastewater safely. KG Contracting handles percolation testing, permitting, and full installation or replacement, accounting for the slower percolation rates and rocky subsurface common throughout Williams.
Gravel or Loose Fill Paving – Install, Spread, or Scrape
Gravel remains one of the most practical surfacing options for driveways, access roads, and parking areas in Williams' climate. KG Contracting installs new gravel surfaces, spreads loose fill material, and scrapes existing gravel to correct ruts and restore an even grade.
Get Started with KG Contracting
Planning a construction project in or around Williams, Flagstaff and Northern AZ often means juggling permitting timelines, seasonal weather windows, and multiple contractors trying to coordinate around each other. KG Contracting simplifies that process by handling excavation, grading, septic work, gravel paving, and site clearing as a single, coordinated service.
Property owners and developers who reach out early in the planning process typically have the most flexibility with scheduling, since excavation and grading work often needs to happen before other trades can begin. Whether the next step is a residential building pad, a septic system replacement, or a full commercial site preparation project, getting a professional site evaluation early helps avoid costly surprises once construction is underway.
