Excavation Cost Richmond Hill: Real 2026 CAD Pricing From a Local Contractor

Most Richmond Hill homeowners calling us want one number before anything else: what’s the excavation going to cost. Fair question. Here’s the honest answer up front. A typical residential excavation job in Richmond Hill runs $4,500 to $38,000 CAD depending on what you’re digging, how the lot sits, and what we hit two feet down. Small trenching jobs start around $2,800. Full basement dig-outs on a tight Bayview lot can push past $45,000. Everything in between has a real range, and we’ll give you all of it on this page.

OCM Excavation & Construction has been digging Richmond Hill since 2008. Seventeen years of basements, pools, sewer laterals, swales, and foundation work between Yonge, Bathurst, 19th, and Stouffville Road. We carry $2M Commercial General Liability through Definity (current certificate provided with every quote) and is current. Owner-operated by Ofer Hadad. Below is the real pricing, the real reasons it moves, and the Richmond Hill-specific stuff most contractors don’t tell you until the invoice lands.

Per-Cubic-Yard Excavation Pricing in Richmond Hill

Most excavation in the GTA gets quoted on a cubic-yard basis once we know what we’re moving. In Richmond Hill the working range in 2026 is $85 to $185 per cubic yard, all-in, including the dig, haul, and dump fees. That’s a wide spread, and it’s wide for a reason.

Here’s what moves a Richmond Hill cubic-yard price inside that range:

Soil type. The dense till you hit around Oak Ridges, Lake Wilcox, and the northern half of Richmond Hill is roughly 30 to 40 percent slower to dig than the looser silty loam south of Major Mackenzie. Slower dig, more machine hours, higher per-yard cost.
Haul distance to a licensed dump. Closest clean-fill sites for Richmond Hill jobs are in Vaughan and Whitchurch-Stouffville. Round trip is usually 35 to 70 minutes. Each truck cycle is billable.
Access. A drive-around side yard with 10 feet of clearance is a different machine and a different price than a backyard you can only reach by craning equipment over a fence.
Contamination or fill material. Clean native soil dumps for $14 to $22 per tonne. Mixed fill with brick or asphalt runs $32 to $55. Anything flagged by an environmental report (oil staining, urea-formaldehyde, old fuel tanks) goes to a Class 1 or 2 facility at $95 to $240 per tonne.
Frost season. December through mid-March in Richmond Hill, we’re digging through frost down to roughly 1.5 metres. That adds machine time and sometimes a thaw blanket rental.

For a quick gut check: an average two-car driveway dig-down to install permeable pavers is around 28 to 36 cubic yards. At Richmond Hill rates that’s $2,400 to $6,600 of excavation alone, before the base, the pavers, or the disposal of any old asphalt.

Common Richmond Hill Excavation Job Costs (Real CAD Ranges)

These are the jobs we quote most often in Richmond Hill. Ranges are 2026 CAD, turnkey (machine, operator, labour, hauling, dump fees, basic restoration). Permit fees and engineered drawings are extra where noted.

Basement dig-out / lowering existing basement: $22,000 to $58,000 for a typical 1,000 to 1,400 sq ft footprint. Underpinning and bench-footing engineering adds $3,500 to $7,500 for the structural drawings and Town review.
New foundation excavation (custom build or rear addition): $8,500 to $24,000 for a standard 8-foot dig. Walkout basements on Richmond Hill’s sloped lots near Mill Pond or Jefferson Forest typically run $18,000 to $32,000 because of the extra grading.
Inground pool removal (full demolition and fill): $9,200 to $18,500 for a standard 16×32 concrete or vinyl pool. Fibreglass shells on the higher end because of disposal complexity.
Sewer lateral replacement (house-to-street): $6,800 to $16,000 depending on depth, length to the property line, and whether we can open-cut or have to bore under a mature tree. Town of Richmond Hill road-cut permits add $480 to $1,250.
Drainage trenching (weeping tile, French drain, swale tie-in): $48 to $95 per linear foot for trench, pipe, gravel, sock, and backfill. Most Richmond Hill backyards land at $4,500 to $11,000 turnkey.
Lot grading and swale work for Town drainage approval: $3,800 to $14,500. The grading certificate from a P.Eng or OLS runs another $850 to $2,400 and is required by the Town before deposit return on new builds and major additions.
Window well install with excavation: $2,400 to $4,800 per well, more if we’re tying into existing weeping tile.
Driveway excavation and base prep (full removal and re-base): $4,800 to $14,000 for a typical Richmond Hill double-wide.

If your job isn’t on this list, it doesn’t mean we don’t do it. It just means the price is too case-specific to publish without seeing the site. Call 416-317-3090 and we’ll come look.

What Drives Richmond Hill Excavation Prices

Richmond Hill is not Vaughan and it’s not Markham, even though it’s wedged between them. The pricing differences come from five real, measurable things.

1. Lot grade. Anything north of Elgin Mills, and most of the King-Bayview corridor, sits on slopes from 4 to 18 percent. Sloped excavation needs benching, temporary shoring, or a wider work zone. Add 10 to 25 percent over flat-lot pricing.

2. Soil density. Richmond Hill north of 16th Avenue sits on Halton Till, which is glacial silty clay with stones. It’s dense, it’s heavy, and it dulls bucket teeth fast. The southern stretch near Yonge and Carrville is closer to Newmarket Till with sandier inclusions. We’ve seen the same-size basement dig take 30 hours on one lot and 48 hours on a lot four kilometres north. That’s real money.

3. Oak Ridges Moraine. The northern third of Richmond Hill sits on the Oak Ridges Moraine Conservation Area. Anything inside the moraine boundary triggers extra environmental review and sometimes a TRCA permit. Add $1,200 to $4,800 in permit, study, and timeline cost for moraine lots.

4. Town permit fees and grading approval. Building permits for foundations are calculated on construction value. For a typical basement underpinning or new foundation, expect $680 to $2,100 in Town fees. Lot grading deposits run $1,000 to $5,000 and are refunded after the Town inspects the final grade against your approved drawing.

5. Disposal of contaminated soil. Older properties south of Major Mackenzie sometimes hit buried fuel tanks, fill from demolished farm structures, or 1970s urea-formaldehyde foam in foundation walls. If a Phase II ESA flags it, soil goes to a regulated facility at $95 to $240 per tonne instead of the $14 to $22 clean fill rate. A single basement dig with contaminated soil can add $8,000 to $22,000 to the bill. We’d rather find out on day one than day eight.

Richmond Hill-Specific Gotchas Most Quotes Miss

These are the things that show up on Richmond Hill jobs that don’t show up the same way in Toronto or Mississauga. Any contractor quoting your job without addressing them is guessing.

Frost depth. Local code treats 1.5 metres as the minimum frost line for footings and water lines in Richmond Hill. Shallower digs leak, heave, and fail inspection. Anyone quoting a 1.2 metre footing depth here is wrong.
Lake Wilcox high water table. Properties within roughly 400 metres of Lake Wilcox often hit groundwater between 1.8 and 2.4 metres down. That means dewatering pumps, discharge permits, and sometimes a temporary sump. Budget $1,400 to $4,600 extra.
Mature tree preservation. Richmond Hill’s tree by-law protects any tree with a trunk diameter over 20 cm on private property. Excavating within the critical root zone of a protected tree without an arborist report and a tree-protection permit is a fineable offence. Permit and arborist review costs $450 to $1,800.
Steep driveways. A lot of older Richmond Hill driveways pitch 12 to 18 percent. We’ll often need a tracked machine instead of a wheeled one, or we’ll have to stage at the road and wheel material in. Equipment swap can add $600 to $1,800.
Town permit office. Richmond Hill Building Division is at 225 East Beaver Creek Road. Permit intake line is 905-771-8800. We pull permits for you on every job that needs one. You don’t drive down there yourself.

How OCM Keeps Richmond Hill Quotes Predictable

The reason most homeowners get burned on excavation isn’t the headline number. It’s the change orders. The quote says $18,000, the final bill says $31,000, and nobody can explain the $13,000 in writing. Here’s how we keep that from happening.

On-site assessment before we quote. Ofer or a senior estimator walks your lot. We probe soil where we can. We check access, slope, hydro setbacks, and tree-protection zones. We look at your survey and your drainage plan if you have them. No phone quotes for excavation work over $5,000.
Fixed-price quotes in writing. Once we’ve seen the site, we give you one number with the scope spelled out line by line. Machine hours, haul truck cycles, disposal class, restoration, permit pull.
Named conditions that can change the price. The only things that move a fixed quote are written conditions you sign off on up front: discovery of contaminated soil flagged by lab test, bedrock above the dig line, or a scope change you request. Everything else is on us.
Daily progress photos. You get end-of-day pictures by text or email so you can see exactly where we are without having to come home.
Full insurance and on every quote. $2M CGL through Definity (current certificate provided with every quote). insurance details certificate goes with every quote so you’re not personally liable if a worker gets hurt on your property.

Seventeen years in. Most of our work in Richmond Hill now comes from neighbours of people we’ve already dug for. That only happens when the price you sign is the price you pay.

Richmond Hill Excavation Cost FAQ

How much does it cost to excavate a basement in Richmond Hill?

A full basement dig-out or basement-lowering project in Richmond Hill runs $22,000 to $58,000 CAD in 2026, covering excavation, haul, dump fees, and basic restoration.

What does a pool removal cost in Richmond Hill?

Inground pool removal in Richmond Hill runs $9,200 to $18,500 CAD for a typical 16×32 concrete or vinyl pool, fully demolished, hauled, and backfilled with engineered fill compacted in lifts. Fibreglass shells run higher because of disposal complexity. Partial removals (top three feet broken in, deck demolished, pool basin filled) sit at the low end. Full removals required for a future build land in the upper half. Town of Richmond Hill demolition permits add $250 to $620.

How much per cubic yard is excavation in Richmond Hill?

Excavation in Richmond Hill is typically $85 to $185 per cubic yard in 2026, all-in, including dig, haul, and dump fees. The lower end applies to flat lots with loose soil, good access, and clean native fill going to a nearby site. The upper end applies to dense Halton Till on sloped Oak Ridges lots, contaminated material requiring a Class 1 facility, or restricted-access backyards needing smaller equipment. On-site assessment is the only way to land your price inside that range accurately.

Do I need a permit to excavate in Richmond Hill?

Most excavation tied to a foundation, addition, basement underpinning, pool removal, or sewer lateral replacement in Richmond Hill requires a Town permit. Lot grading and drainage changes need approval against your registered grading plan. Building permit fees typically run $680 to $2,100. The Town Building Division is at 225 East Beaver Creek Road, intake line 905-771-8800. OCM pulls all required permits as part of your fixed-price quote. You don’t deal with the Town counter yourself.

Why is excavation more expensive in north Richmond Hill?

North Richmond Hill, roughly north of Elgin Mills, sits on the Oak Ridges Moraine with denser Halton Till soil, sloped lots, and stricter environmental review through TRCA. Same-size dig can take 30 to 50 percent more machine time than a flat south-end lot. Moraine permits and reviews add $1,200 to $4,800. Steeper grades sometimes require benching or shoring. All of that is real cost, not markup. Quotes should itemize it so you see exactly where the difference comes from.

What’s included in an OCM excavation quote?

Every OCM Richmond Hill quote includes machine time, qualified operator, all labour, haul trucks, dump fees for the soil class confirmed on site, basic site restoration (rough grade and seed where applicable), Town permit pull where required, and daily progress photos to you. $2M CGL coverage from Definity; current certificate of insurance certificate provided with every quote. Engineered drawings, arborist reports, dewatering, and lab testing are quoted separately and only when your job actually needs them.
