About DK Excavation

Services & Process

DK Excavation combines excavation, demolition, and septic services, making them well-suited for full system installations, drain field replacements, and projects that require significant site prep. Excavation work for septic projects involves digging to the required depth and dimensions for new tanks, distribution systems, and drain field trenches while meeting county health department specifications. Demolition services come into play when old tanks need to be decommissioned and removed from a site. For Monroe-area properties switching from older systems or setting up new builds, having excavation and septic work handled by one crew simplifies the process considerably.

Service Area

DK Excavation serves Monroe and the surrounding communities throughout Snohomish County. Nearby areas including Sultan, Snohomish, Duvall, and Startup are within their typical project range. Rural properties in the foothills east of Monroe along US-2 are also a regular part of their service territory.

Frequently Asked Questions

Do I need an excavation company for a septic system replacement in Monroe?
Yes, replacing a septic tank or drain field requires significant digging that goes well beyond what a standard pump truck can handle. An excavator is needed to safely expose the old system, remove it if necessary, and install the new components at the correct depth. Having one company handle both the excavation and the septic work saves you from coordinating two separate contractors.
How long does a new septic system installation take in Snohomish County?
The timeline depends heavily on permitting, which can take several weeks through the Snohomish County Health Department. Once permits are in hand, the physical installation on a standard residential lot typically takes 1 to 3 days. Weather and soil conditions in the Monroe area can also affect scheduling, particularly during the wet season.
What types of septic systems are approved for rural properties near Monroe, WA?
Snohomish County approves several system types depending on soil perc test results and lot size, including conventional gravity systems, mound systems, and advanced treatment units for lots with challenging soil. A soil evaluation and site design must be completed by a licensed designer before any permit is issued.
Can DK Excavation decommission my old septic tank if I'm connecting to city sewer?
Yes, decommissioning an old tank involves pumping out remaining contents, crushing or filling the tank to prevent collapse, and obtaining proper closure documentation as required by the county. This is a required step when connecting to a public sewer system, and skipping it can create liability and safety issues for the property owner.
How much does a new septic system installation typically cost in the Monroe area?
Costs vary widely based on system type, soil conditions, and site complexity, but a conventional residential system in Snohomish County often runs between $15,000 and $30,000 or more when including excavation, materials, and permitting fees. Mound systems or advanced treatment systems cost more due to additional materials and engineering requirements. Getting a site-specific estimate is the only way to get an accurate number.
Does DK Excavation handle emergency septic failures, or only planned installations?
They handle both, and a failing system that's backing up into the home or surfacing in the yard is treated as a priority. Emergency situations may require a temporary solution like pumping to keep the system functional while permits for a replacement are processed. Call directly to explain your situation and they'll advise on the fastest path to a fix.
