Excavation & Site Work Services in Greater Seattle
Every great build starts with the ground beneath it. Whether you are preparing a lot for new construction, clearing a site for a DADU, or need utility trenching for a remodel, proper excavation and site work sets the foundation for everything that follows.
At Waltier Homes, we offer comprehensive earthworks services throughout Greater Seattle. As builders ourselves, we understand what it takes to prepare a site correctly — because we are the ones who build on it. That perspective means we approach every excavation project with the precision and foresight that only a full-service construction company can deliver.
Excavation Service
Site Preparation
Preparing your land for construction requires more than just moving dirt. We clear vegetation, remove debris, and level your site to create the optimal starting point for your project. Proper site prep prevents costly issues down the road and ensures your build starts on solid ground.

Foundation Excavation
Precise foundation excavation is critical to structural integrity. We dig accurate trenches and pits for building foundations, basements, and footings — with the exact dimensions and depths your project requires. Our crews understand Seattle's soil conditions and how to work with them.

Utility Trenching
Underground utilities require careful planning and precise execution. We create trenches for water lines, sewer connections, gas mains, electrical conduits, and communication cables. Every trench is properly excavated, graded, and ready for installation.

Drainage Solutions
Seattle's rain is no secret. Proper drainage protects your investment from water damage, erosion, and foundation issues. We design and install drainage systems that manage stormwater effectively and keep your property dry.
GRADING SERVICES
Proper grading ensures a stable foundation and effective water management. Poor grading leads to standing water, erosion, and structural problems. We get it right the first time.
Our grading services include:
• Site Leveling — Creating a level, stable base for construction
• Slope Creation — Designing grades that direct water away from structures
• Driveway & Road Grading — Preparing surfaces for paving with proper drainage
• Landscape Grading — Shaping terrain for functional and attractive outdoor spaces
TIMELINE: 2-4 weeks

DEMOLITION & TEARDOWN
Sometimes building new means clearing the old. Our demolition services safely and efficiently remove existing structures to make way for your new project.
What to expect:
1. Initial Assessment — We evaluate the structure, identify hazards, and develop a demolition plan
2. Permitting — We handle all required permits and ensure compliance with local regulations
3. Site Preparation — Utilities are disconnected, safety barriers installed, and adjacent properties protected
4. Demolition — Systematic teardown using appropriate equipment and techniques
5. Cleanup & Haul-Away — Complete debris removal, leaving your site clean and ready for construction
TIMELINE: 2-4 weeks
