What deposit and payment schedule is standard for interlock projects in Metro Vancouver?

Standard practice in Metro Vancouver is a 10-20% deposit to secure your project start date, with progress payments tied to completion milestones rather than upfront lump sums. Reputable contractors typically request 50% upon material delivery, 40% at substantial completion, and final 10% after your approval and any punch-list items are resolved.

Typical Payment Schedule for Interlock Projects

Initial deposit of 10-20% is reasonable to book your project and cover initial material ordering. For a $15,000 paver patio, this means $1,500-$3,000 upfront. Contractors use this deposit to purchase materials and secure your spot in their schedule. Be wary of contractors requesting deposits over 25% or demanding large upfront payments before any work begins.

Material delivery payment (40-50% of total) becomes due when pavers, base materials, and supplies arrive on site. This timing protects both parties — you can verify the correct materials have been delivered, and the contractor has covered their largest expense. For that $15,000 patio, you'd pay $6,000-$7,500 at material delivery.

Substantial completion payment (30-40%) is due when the installation is essentially complete — pavers are laid, joints are sanded, cleanup is finished, but before final inspection and any minor adjustments. This leaves enough retained to ensure the contractor returns to address any concerns during your final walkthrough.

Final payment (5-10%) is released after your final approval, typically 7-14 days after substantial completion. This retention ensures any punch-list items (minor leveling adjustments, additional joint sand, final cleanup) are completed to your satisfaction.

Metro Vancouver Market Considerations

Material costs represent 40-60% of total project cost in Metro Vancouver's expensive market, so the material delivery payment is often the largest single payment. Concrete pavers run $3-$8 per square foot, natural stone $8-$20 per square foot, plus base materials, polymeric sand, and edge restraints. A 400 sq ft patio requires $2,400-$4,800 in materials alone.

Labour rates of $8-$20 per square foot mean contractors need steady cash flow to cover crew wages, equipment costs, and WorkSafeBC premiums. However, legitimate contractors should never demand full payment upfront or request unusual payment methods like e-transfers to personal accounts, cryptocurrency, or cash-only arrangements.

Seasonal scheduling affects payment timing in Metro Vancouver. Projects booked for the busy May-October season may require deposits 2-3 months in advance to secure scheduling. Winter installations (November-March) often have more flexible deposit requirements since demand is lower, though weather delays can affect payment milestones.

Red Flags to Avoid

Never pay large sums upfront — contractors requesting 50%+ before starting work or full payment before completion are high-risk. Legitimate contractors have established supplier relationships and don't need customers to finance their material purchases weeks in advance.

Door-to-door contractors demanding immediate deposits are almost always problematic. Reputable interlock contractors are booked weeks or months ahead and don't need to solicit work door-to-door. They should provide written estimates, references, and time to consider the proposal.

Cash-only or unusual payment requests are warning signs. Professional contractors accept cheques, e-transfers to business accounts, and credit cards. Be suspicious of contractors who insist on cash, personal account transfers, or cryptocurrency payments.

No written contract or payment schedule leaves you vulnerable. Every interlock project should have a detailed written contract specifying materials, work scope, timeline, total cost, and payment schedule. Verbal agreements are difficult to enforce if problems arise.

Protecting Yourself

Verify WorkSafeBC coverage before making any payments. All professional contractors in BC must carry WorkSafeBC coverage. You can verify coverage online at worksafebc.com using the contractor's business name or account number.

Check references and view recent projects before signing contracts or making deposits. Established interlock contractors should readily provide references from recent projects and photos of completed work. Drive by recent installations if possible.

Use business accounts for all payments and maintain detailed records. Pay by cheque or e-transfer to the contractor's registered business account, never to personal accounts. Keep copies of all contracts, invoices, and payment records.

Understand lien rights in BC. If a contractor doesn't pay their suppliers or subcontractors, those parties can file liens against your property even if you've paid the contractor in full. This is another reason to avoid large upfront payments and to verify the contractor's financial stability.

For complex projects like engineered retaining walls or large driveways, some contractors may request modified payment schedules tied to specific milestones (excavation complete, base installed and compacted, pavers laid, final completion). This is acceptable as long as no single payment exceeds 50% of the total contract value.
