When planning a renovation in Ottawa, one of the first decisions is who to hire: a general contractor who manages the entire project, or specialty contractors hired directly for specific trades. The right choice depends on the scope of your project, your available time, and your comfort with coordination and risk. Choosing wrong can mean either paying a management premium you did not need or taking on coordination headaches you were not prepared for. This guide explains what each type of contractor does, the trade-offs between them, and how to decide which approach fits your renovation.
Understanding the roles is the foundation for choosing between them.
A general contractor takes responsibility for the entire project. They plan and schedule the work, hire and coordinate subcontractors, manage quality control, pull permits, order materials, handle inspections, and solve problems as they arise. You have one point of contact and one contract for the w...
A specialty contractor focuses on a single trade or area — roofing, flooring, electrical, plumbing, painting, or similar. You hire them directly for that specific scope. For a single-trade project, such as replacing a roof or refinishing floors, hiring the specialist directly is often the most effic...
Each approach has real advantages and real costs. The right choice balances money against time, expertise, and risk.
The advantages are convenience, coordination, accountability, and expertise — the general contractor absorbs the complexity and stands behind the whole result. The cost is a management fee, typically a percentage of the project, that pays for that coordination. For complex projects, this fee usually...
Hiring specialty contractors directly and managing them yourself can save 10% to 20% by removing the management fee. The catch is that you become the project manager — responsible for scheduling, coordinating trades, sequencing the work correctly, sourcing materials, pulling permits, quality control...
A simple test helps most homeowners decide.
Your project involves multiple trades, structural work, permits, or a tight timeline, or when you lack the time or construction knowledge to coordinate it yourself. Kitchen renovations, basement finishing, additions, and whole-home projects almost always benefit from a general contractor managing th...
Your project is a single, self-contained trade — a new roof, replacement windows, refinished floors, or a paint job — with little coordination required. In these cases hiring the specialist directly is usually faster and more economical, with no need for a general contractor's oversight.
A general contractor manages an entire project — scheduling, hiring and coordinating subcontractors, permits, quality control, and problem-solving — under one contract. A specialty contractor focuses on a single trade like roofing or flooring, hired directly for that specific scope.
For multi-trade projects involving structural work, permits, or tight timelines — like kitchens, basements, additions, and whole-home renovations — a general contractor is usually worth it. For a single-trade job like a roof or flooring, hiring the specialty contractor directly is often more efficient.
General contractors typically charge a management fee as a percentage of the project cost in exchange for coordination, scheduling, quality control, and accountability. For complex projects this fee usually pays for itself through time saved, fewer mistakes, and a better result.
Potentially 10% to 20% by removing the management fee, but you become the project manager — responsible for scheduling, coordination, sequencing, materials, permits, quality, and liability. Without construction knowledge and significant time, mistakes can easily cost more than you save.
It can be. Trades must be scheduled and sequenced correctly, and a single coordination error can cause delays and added costs. You also take on liability and quality control. Self-management suits experienced, available homeowners on simpler projects, not most multi-trade renovations.
