Why Licensing and Insurance Matter

In Ontario, retaining walls over 1.0 m in height typically require a building permit and must comply with the Ontario Building Code. Unlicensed work can lead to fines, failed inspections, and walls that fail under pressure. Always insist on proof of liability insurance and WSIB coverage—this protects you if a worker gets injured on your property. A licensed contractor will also pull the necessary permits and schedule inspections, keeping your project legal and safe.

Choosing Between Concrete and Interlocking

Concrete retaining walls offer unmatched durability and a modern aesthetic, ideal for long spans or heavy loads. Interlocking blocks, on the other hand, provide flexibility and easier repairs if the ground settles. Both can be reinforced with geogrid for added stability. Your choice should consider soil type, drainage, and the wall’s purpose—whether it’s a decorative garden border or a structural support for a driveway. A skilled contractor will assess these factors during a free consultation.

Questions to Ask Before Hiring

Don’t just get three quotes; interview each candidate. Ask for references from recent projects in Cambridge or nearby areas. Request to see photos of walls that are at least three years old—this reveals how they handle freeze-thaw cycles. Inquire about their drainage approach: a proper wall includes gravel backfill and weep holes to prevent hydrostatic pressure. Also, confirm if they subcontract the work or use their own crews, as this affects accountability.

The Permit Process in Cambridge

Permits can take two to four weeks in summer, so plan ahead. Your contractor should handle the application and include engineered drawings if the wall exceeds 1.2 m. The city will inspect the excavation, base preparation, and final construction. Skipping permits can delay your project or force you to tear down the wall later.

Why Turnkey Management Saves Hassle

A turnkey contractor handles everything from design to inspections to cleanup. This means one point of contact, coordinated scheduling, and no finger-pointing if issues arise. They’ll also manage subcontractors like excavators or concrete finishers, ensuring the job stays on track. For busy homeowners, this peace of mind is invaluable—especially during summer when demand is high and timelines tight.
