About Us

As rural homeowners ourselves, we understand that a septic system designed for your property, properly installed, and well-serviced throughout its lifetime is extremely important. Septic problems can be costly, damaging to your landscape, and hazardous to your family's health. That's why Marchington Excavation puts the utmost emphasis on being your all-in-one provider of reliable septic installations. We make sure your septic system installation is completely tailored to fit your property and done right the first time, so you can have peace of mind for years to come.

We take the same care and attention with every project we take on — whether it's installing a drainage system, clearing a lot for a new home build, or trenching utility lines for a rural property.

Quality You Can Trust

We do the job right the first time — every time. We use proper materials, follow Ontario Building Code requirements to the letter, and never cut corners on installation. A properly installed septic system should last 25-30+ years, and we build every system with that standard in mind.

Affordable, Honest Pricing

We provide detailed, transparent estimates with no hidden fees or surprise charges. Our mission is to deliver high-quality excavation services while remaining competitive. We'll always tell you what a job will cost before we start.

Owner on Every Job

Unlike larger companies where you speak with a salesperson but never meet the crew, William Marchington personally leads every project. You'll deal directly with the owner from your first phone call through final inspection. That means direct accountability and clear communication throughout your project.

Fully Licensed, Insured & Bonded

Marchington Excavation carries full liability insurance and is bonded for your protection. All our work is performed in compliance with the Ontario Building Code and local municipal regulations. We work closely with the Mississippi Valley Conservation Authority (MVCA), Rideau Valley Conservation Authority (RVCA), and South Nation Conservation Authority on all septic permit requirements.
