Preferred Excavation Service provides expert septic services for both residential and commercial properties. Our licensed team ensures your system is properly designed, excavated, and installed according to code. This is the case whether you need a new installation, replacement, or repair. We’ve served Idaho for decades and understand how to manage septic projects in a wide range of terrains and conditions.


Our process begins with site assessment. We evaluate soil, slope, and space requirements. Then we excavate using specialized equipment including excavators, trenchers, and dump trucks to dig precise trenches and tank placements. Once the components are installed, we perform backfill and site restoration to leave your property safe and functional.


Septic system projects are best done during dry weather for better soil access and inspection accuracy. Our systems are designed to meet local health and environmental standards, ensuring long-term performance and safety.

What to Look for in a Septic Contractor:


Hiring a qualified septic services provider is essential to avoid future system failures or environmental issues. Look for a company that is fully licensed, insured, and experienced in both residential and commercial septic installations and repairs. They should be familiar with local soil types, permitting processes, and regional compliance.


Ask about the equipment they use, how they handle drainage planning, and if they provide complete start-to-finish solutions. The best septic contractors offer a clear breakdown of costs, timelines, and maintenance options for long-term success. A strong reputation backed by references and completed projects speaks volumes about their reliability.


A trustworthy provider will prioritize safety, precision, and long-term performance in every job. They will take time to explain your options, work with local inspectors, and ensure everything is done right from excavation to final inspection.
