Excavation & Site Prep · Seattle
Excavation & Site Prep in Seattle
People in Seattle call Greg for land clearing, grading, building pads and drainage. He's a licensed, bonded and insured general contractor out of Rainier, about 55 miles away, and every Seattle job starts with a free estimate.
In the older neighborhoods here, a lot of the work is remodels, additions, ADUs and decks on tight lots, built to the city's permit and inspection schedule. Getting the dirt work right protects everything that gets built on top of it.
One customer called Greg “a man of integrity.” Another wrote that he “does excellent work.”
What's included
Excavation & Site Prep we do in Seattle
- 01
Land clearing
Trees, brush, stumps and blackberries removed, with debris hauled off or chipped, so the site is open for layout.
- 02
Grading and building pads
Cut and fill to set the pad at the right height, with structural fill compacted in layers so it doesn't settle under your foundation or slab.
- 03
Foundation excavation
Footing trenches, crawl space digs and basement or walk-out excavation taken down to firm, undisturbed soil.
- 04
Gravel driveways and access roads
Stripped, rocked and compacted driveways that hold up to concrete trucks and lumber deliveries during the build and daily traffic after.
- 05
Drainage
French drains, curtain drains, footing drains and swales that move water away from the building and out of the low spots.
- 06
Utility trenching
Trenches for water lines, power conduit and other service lines, backfilled and compacted once the lines are in.

Excavation & Site Prep around Seattle
Greg works all over Seattle — near Belltown, Uptown and Tilikum Place and out by Bell Street Park and Seattle Children's Museum — and throughout King County.
Seattle is the biggest city in our service area, about 55 miles north of our base in Rainier. Seattle is about 55 miles north of our base in Rainier, well inside our 100-mile service area.
Western Washington buildings fight water more than anything — months of rain, moss on the roof, rot wherever wood stays wet, and soils that hold moisture. A building lasts when it sits on a proper foundation with drainage around it, is wrapped and flashed right, and is built to dry out.

Excavation & Site Prep: what it can look like
How it works
How your Seattle excavation job works

Free on-site estimate
Greg walks the property with you, looks at the trees, slope, soil and wet areas, and talks through where the building, driveway and drainage should go.

Permits and staking
The clearing and grading permits your county requires are handled, and the pad, driveway and drainage paths are staked out.
- 3
Clear, cut and compact
Clearing, stripping, cut and fill and compaction happen in order, with erosion control in place so the mud stays on your site.

Final grade
Pad, driveway and drainage are checked for grade, and the site is left ready for the foundation, slab or building.

Questions
Excavation & Site Prep in Seattle: FAQs
Do you do excavation & site prep in Seattle, WA?
Yes. Seattle is about 55 miles north of our base in Rainier, well inside our 100-mile service area. Greg handles land clearing, grading, building pads and drainage there, and the estimate is free.
Do I need a permit for excavation & site prep in Seattle?
It depends on the project. When one is needed, Greg pulls the permit from the City of Seattle's building department and builds to whatever the permit and inspection require.
Can you do excavation during the wet season?
Yes, but it takes more care. Clay and glacial till turn to mud fast when they are worked wet, so Greg schedules heavy grading for drier stretches when he can, protects exposed subgrade, and uses rock where the ground won't dry out. A site with a high water table may also need drainage put in before the pad is built.
How much does excavation and site prep cost?
It depends on how many trees and stumps come out, how much soil has to be cut, filled or hauled, how much rock the driveway and pad need, the drainage required, and how easy the site is to reach. Two lots of the same size can be very different jobs. Greg's on-site estimates are free.
Do I need a permit to clear or grade my land?
Often, yes. Counties regulate clearing and grading past certain amounts, and land near wetlands, streams or steep slopes can need extra review. Greg checks your county's requirements before work starts so the project doesn't stall halfway through.
What is a building pad, and why does it matter?
It is the leveled, compacted ground your foundation or slab sits on. If the pad is built on soft soil or loosely dumped fill, the building settles and cracks. Greg digs to firm ground and compacts fill in layers so the pad stays where it was built.
