Serving the Comox Valley

Excavation Services in Comox, BC

Comox offers fast digging in Quadra Sand, though coastal floodplain rules require early planning on waterfront lots.

Courtenay Excavating works across the Comox Peninsula in Quadra Sand, the same material visible along the Willemar Bluffs and Goose Spit. Sand digs fast, so most scopes here sit at the low end of our ranges — but a sand trench wall will not stand, so anything over 1.2 metres gets sloped, benched or shored. If your property is within 100 metres of the Strait of Georgia, a coastal floodplain assessment may apply, and we settle that before booking a machine.

Excavation in Comox commonly runs $3,000 to $20,000 for site preparation and $3,000 to $12,000 for drainage or trenching, with sand subgrades often landing toward the lower end. Hourly with an operator, that is $142 to $169 for a mini excavator (Class 1–3) and $180 to $248 for a standard excavator (Class 4–8). All of it stays a planning range until we have walked the property.

Comox is the sand side of the valley. That makes most excavation cheaper and one part of it more dangerous.

What the bluffs say about the ground

The Willemar Bluffs along the Comox waterfront clearly showcase the area's deep Quadra Sand layers, which gradually washed down over time to form Goose Spit. That same Quadra Sand runs under most of the peninsula.

Sand is the easiest material in the valley to excavate and among the easiest to compact. Drainage is rarely the problem it is on the Courtenay flats, and a building pad on sand usually sits at the low end of every cost range.

The trade-off is stability. A sand face will stand vertical and look completely sound — right up until it fails. That is why WorkSafeBC's 1.2 metre threshold for sloping, benching or shoring applies to routine utility trenches in sand, as well as deep foundation digs.

Coastal setback, floodplain and the 100 metre line

The CVRD building checklist requires a coastal floodplain assessment for any construction project within 100 metres of the Strait of Georgia. On a peninsula town that catches a lot of ground.

Because the Town of Comox manages its own municipal building permits, town guidelines govern properties inside town boundaries. Every waterfront property runs into the same question: how high does liveable space have to sit, and what does that do to the dig?

Waterfront construction near Comox Harbour and the K'ómoks Estuary requires environmental foreshore reviews before digging starts. We settle those questions before we book a machine.

A smaller town on a finite peninsula

The town sits on a peninsula with water on three sides, so most of our work here is on established properties rather than raw lots.

That shifts the typical job. Replacing a silted perimeter drain on a 1970s house, adding a shop pad behind an existing home, upgrading a driveway that was built for one car and now takes three — these are the common scopes, and each is constrained by what is already built.

Access is the recurring cost driver. A machine that has to reach a back yard through a side gate is a different machine, and a different price, from one that can drive onto open ground.

Just outside the town line: Lazo North

Electoral Area B — Lazo North — wraps directly around the Town of Comox, covering rural residential parcels, farms and coastal properties. Properties there look identical to town properties from the road and are governed differently.

In Lazo North, CVRD Building Services handles building permits, requiring attention to septic and rural water connections. If your property relies on septic, your septic filing must land with Island Health before a building permit package is accepted. The location of your drain field determines where we can build your driveway, pad or drainage lines.

Near a septic field, we need to know exactly where it sits and how it's laid out before we dig — that matters more here than the soil type does. Crush the field with the machine and you haven't repaired it. You've replaced it.
