Should I ask my Calgary deck contractor for proof of WCB Alberta coverage before they start work?

Absolutely yes — requesting proof of WCB Alberta coverage should be standard practice before any deck contractor begins work on your property. This protects you from potentially devastating financial liability if a worker is injured during construction.

Why WCB Alberta coverage matters for deck projects: Deck construction involves significant safety risks — working at height, heavy lifting, power tools, concrete work, and structural framing. If an uninsured worker is injured on your property, you as the homeowner may be held personally liable for medical costs, lost wages, and disability benefits. These costs can easily reach hundreds of thousands of dollars for serious injuries like falls from elevated decks or equipment accidents.

What to request from your contractor: Ask for a current WCB Alberta clearance letter before work begins. This document confirms the contractor is registered with WCB Alberta, has paid their premiums, and is in good standing. The clearance letter should be dated within the past 30 days and list the contractor's business name exactly as it appears on your contract. Don't accept expired letters or documents from other provinces — it must be current WCB Alberta coverage.

Red flags to watch for: Be cautious of contractors who claim they don't need WCB coverage because they're "independent contractors" or "work alone." In Alberta, most construction work requires WCB coverage regardless of business structure. Contractors who hesitate, make excuses, or promise to "get it later" may be operating without proper coverage. Similarly, be wary of unusually low bids — they may reflect a contractor cutting corners on insurance and worker protection.

Calgary's construction climate considerations: Given Calgary's short building season (May through October), many contractors are busy and may rush through paperwork. However, legitimate deck contractors understand that WCB verification is standard practice and will provide clearance letters without hesitation. The best contractors often include their WCB number directly on their business cards and estimates.

Additional protection steps: Beyond WCB coverage, verify that your contractor carries general liability insurance (minimum $2 million is standard for deck work) and confirm they have a City of Calgary business license if required. For elevated decks requiring permits, ensure they're familiar with Alberta Building Code requirements and Safety Codes Officer inspections.

When to hire a professional: Any deck over 600mm (24 inches) above grade requires professional construction due to structural complexity, permit requirements, and safety risks. These projects involve footing excavation to Calgary's 4-foot frost depth, proper ledger board attachment, and life-safety railing installation — all high-risk work where proper insurance coverage is essential.
