How Much Does Excavation Cost in the Comox Valley?
Courtenay Excavating prices excavation work across Courtenay, Comox and Cumberland either by the hour or as a whole-project range. Our machine and operator rates run from $142 to $398 per hour depending on equipment size. Site preparation typically ranges from $3,000 to $20,000, and we give you a clear written estimate after walking your property.

When we quote excavation, we price the machine time, the operator time, what gets moved, and what gets hauled away — based on what we find when we walk the site, never a flat rate per square foot.
Because soil conditions vary across every lot, we walk your property and inspect the ground before giving you a written price range. Here's what the work actually costs in the Comox Valley in 2026, what drives the spread, and which numbers you can treat as firm.
For what these numbers buy on a specific property, start with site preparation.
| Work | Typical range | Priced by | What moves it most |
|---|---|---|---|
| Site preparation & lot grading | $3,000 – $20,000 | Project | Lot size, cut-to-fill balance, imported structural fill |
| Foundation excavation | $4,000 – $15,000 | Project | Depth, soil type, groundwater, machine access |
| Land clearing | $3,000 – $10,000+ per acre | Per acre | Stem density, stump size, slash disposal distance |
| Driveway & access build | $3,000 – $12,000 | Project | Length, culvert size, imported granular base |
| Perimeter drainage | $3,000 – $12,000 | Project | Trench length, depth, drain rock and fabric quantity |
| Utility & service trenching | $3,000 – $12,000 | Project | Run length, depth, whether spoil stays on site |
| Rock breaking (hammer work) | Quoted separately | Hourly | Volume, hardness, proximity to structures |
What actually drives the spread
Four things move your quote more than anything else, and none of them are visible from the road.
Soil comes first. Quadra Sand digs fast, compacts readily, and needs no dewatering — a pad on sand sits close to the low end of every range above. Vashon till is slower, needs moisture control, and can force a weather-dependent schedule. Floodplain silt near the Courtenay, Puntledge and Tsolum rivers brings groundwater into scope, and a dewatering requirement can add more than the excavation itself.
Access is second. A machine that can drive onto the lot costs less than one that has to be floated in, and a lot with no room to stockpile forces every cubic metre of cut to leave the property.
Haul and disposal is third. Keeping soil and rock on your property saves money, while hauling material off site adds loading, trucking and tipping fees. Balancing cut and fill on the same lot is the single largest saving available on most residential jobs.
Rock is fourth and the least predictable. Hammer work is quoted separately because the volume stays unknown until the ground is open.
Hourly versus fixed price
We usually quote small, well-defined work by the hour: a short trench, a drain repair, a stump. Machine and operator rates run $142 to $169 per hour for a mini excavator (Class 1–3), $180 to $248 per hour for a standard excavator (Class 4–8), and $257 to $398 per hour for a heavy machine (Class 9–12), with all figures current for 2026 and the operator included.
We quote larger scopes as a written range with the assumptions listed — machine size, estimated hours, haul volume, disposal, and what happens if the ground differs from expectation.
| Machine or basis | Rate with operator | Typical use |
|---|---|---|
| Mini excavator (Class 1–3) | $142 – $169 / hr | Perimeter drains, tight infill lots, service trenches |
| Standard excavator (Class 4–8) | $180 – $248 / hr | Site prep, foundations, driveway builds |
| Backhoe | $180 – $248 / hr | Trenching, backfill, mixed loading work |
| Larger machine (Class 9–12) | $257 – $398 / hr | Bulk cut, rock breaking, large pads |
| Mobilization | Quoted per job | Distance from Courtenay, float needed for larger machines |
The project ranges above reflect typical Comox Valley costs in 2026, while our hourly machine rates cover both the machinery and an experienced operator on site. Treat both as planning figures for budgeting, not as quotes — pricing moves with soil, access, groundwater, haul distance and disposal, and two properties on the same street can differ by a factor of two. We confirm all price figures in writing after walking your property. Updated July 2026.
What is in the quote you get back
We name the machine class, the estimated hours or days, the volume assumed to leave the site, the disposal destination, and the exclusions on every quote. Exclusions matter more than inclusions in this trade — rock, unexpected groundwater, contaminated material, and utility conflicts are the four that show up most often.
We also state on the quote who is filing the BC 1 Call locate and when. The service is free, utility members have three working days to respond, and excavation has to start within 14 calendar days of the request, so we always know exactly when that locate has to go in.
Where approvals apply — a City of Courtenay soil deposit permit, a Ministry of Transportation and Transit access permit, an Agricultural Land Commission Notice of Intent — we say on the quote whether the application is inside the price or the owner's responsibility.
Seasonal scheduling and what it costs
We do not charge a different rate by season, but we do schedule around them, and that can change what a job ends up costing. The valley receives roughly 1,400 mm of annual rain, with most falling between October and April.
Sand-based lots through Merville and Black Creek work year-round. Till and silt lots do not — compacting saturated clay does not work, and machine traffic on wet ground creates rutting and remediation nobody quoted for. Winter work on those soils often means added cost for matting, dewatering, or simply lost days.
So a till or silt site quoted in February and a sand site quoted in July can carry very different contingency, even for identical scopes.
Once we have walked your site
Our quote covers the scope of the work, the access the machine needs to reach it, and the haul-off and disposal of everything that leaves the property. Once we've walked the site, we lock in the price for that scope.

Budget ranges are a starting point — we still need to walk the site to price the actual ground. Send the property details and request a free quote with the assumptions written down.
