About KMJ Excavating

KMJ Excavating is located in Sultan, Washington, a small Sky Valley community in eastern Snohomish County where rural properties frequently require onsite septic systems. Sultan sits along the Stevens Pass corridor between Monroe and Index, an area where lots tend to be larger and municipal sewer service is limited. KMJ's combination of septic services, landscape design, and irrigation sets it apart from single-trade providers. They have 3 reviews with a 3.7 rating, so their customer base is small but the early feedback leans positive.

Frequently Asked Questions

Can KMJ Excavating install a new septic system on my Sultan property?
An excavation-focused company like KMJ is well-suited for full septic system installations, which require significant earthwork to place the tank and construct the drain field. Snohomish County permits and a site evaluation are required before installation begins, so plan for some lead time before work can start.
How do rocky soils in the Sultan area affect septic system design?
Rocky or compacted soils can limit where a drain field can be placed and may require alternative system designs like mound systems or pressure-dosed systems to achieve proper effluent treatment. A contractor familiar with eastern Snohomish County terrain will know what to expect and can help guide the design process.
Can my irrigation and septic system work be done at the same time?
In many cases, yes. Coordinating both projects under one contractor avoids redundant digging and allows the finished grade to be planned with both systems in mind. Discuss your full project scope upfront so materials and sequencing can be properly planned.
What permits are needed for a septic installation near Sultan?
Snohomish County Health District oversees onsite sewage system permits, and you'll typically need a site evaluation, design approval, and installation permit before work begins. The process can take several weeks, so starting the permitting process early is important if you're on a timeline.
How close can a septic system be to the Skykomish River?
Washington State and Snohomish County have setback requirements that keep septic systems a minimum distance from surface water, wells, and property lines to protect water quality. These setbacks vary by system type and site conditions, and a site evaluation will identify any constraints on your specific parcel.
Does KMJ handle drain field repairs as well as new installations?
Given their excavation background, drain field repairs that require digging and replacing failed components are within their likely scope of work. It's worth calling (360) 217-7695 to describe your specific situation and confirm they can handle what you need.
