Before I started Smart Renovations, I spent years inside the cabinetry manufacturing industry – working directly with contractors, designers, and suppliers across the GTA. I watched projects go sideways from the inside. And the single most common root cause wasn’t bad workmanship or bad luck. It was a mismatch between the type of contractor a homeowner hired and the type of project they were actually doing.
A homeowner who hires individual trades for a full kitchen gut renovation will spend weeks managing scheduling conflicts they didn’t see coming. A homeowner who hires a full design-build firm for two rooms of new flooring will pay a premium for overhead they didn’t need. Getting this decision right before you call anyone is the most efficient thing you can do.
Here’s how the three main options work – and how to know which one fits your project.
The Three Types of Renovation Contractors
1. General Contractor (GC)
A general contractor is your single point of accountability for the entire build. Most GCs don’t perform every trade themselves – they hire and coordinate a network of subtrades: licensed electricians, plumbers, drywallers, tile setters, millwork suppliers. What you’re actually paying for is their ability to manage the sequencing, the people, and the problems that come up along the way.
What You Manage
Very little day-to-day. You review decisions, approve selections, and pay according to the agreed schedule.
What They Manage
Subtrade scheduling and coordination, material ordering, permit applications (typically), site supervision, and the overall timeline.
Cost Structure
Fixed project fee or 15-25% markup on labour and materials. That overhead pays for a real project manager.
When a GC makes clear sense
- Your project involves three or more trades (e.g., a kitchen touching plumbing, electrical, and millwork)
- The project spans more than four to six weeks of active work
- You work full-time and can’t be on-site to resolve daily issues
- You want one party contractually responsible if something goes wrong
When the GC model may be more than you need
- The project is genuinely limited to one trade (painting, flooring, a single fixture swap)
- You have renovation experience and can coordinate two tradespeople yourself
- Budget is tight and the management layer is hard to justify
2. Individual Trades (Direct Hiring)
Hiring individual tradespeople directly – your own electrician, your own plumber, your own tile setter – means you become the project manager. In Ontario, this is sometimes called acting as an owner-builder, and it carries real responsibility.
What You Manage
Everything. Sequencing, scheduling handoffs, sourcing materials, resolving conflicts between trades, and making time-sensitive decisions.
What They Manage
Their specific scope only. Your plumber is not tracking what the electrician is doing – coordinating that overlap is on you.
Cost Structure
Pay each trade directly – no GC markup. Can save 15-25% on paper. One scheduling mistake can erase those savings fast.
When hiring trades directly works
- The scope involves one or two trades with no meaningful sequencing dependency
- You’ve done this before and understand how trades hand off to each other
- You have schedule flexibility to be available during business hours
- The project is cosmetic: new flooring, painting, a single bathroom vanity swap
When it gets genuinely risky
- You’re doing a gut renovation and have never managed a multi-trade project before
- You’re underestimating how tightly sequenced a real renovation is (plumbing rough-in, inspection, drywall, tile, fixtures – in that order, every time)
- You’re assuming trades will coordinate with each other without you actively managing it
Hiring directly isn’t inherently a mistake. But it’s a job, and if you’re not prepared for that job, the GC fee is worth every dollar.
3. Design-Build Firm
A design-build firm handles both the design and the construction under one contract and one roof. Rather than hiring a designer or architect separately and then finding a contractor to execute their plans – a process that creates real gaps in accountability – you work with a single team from concept through handover.
At Smart Renovations, this is the model we operate: we’re both a licensed design firm and a licensed general contractor. We develop the 3D design, handle permits, coordinate all trades, and build the project.
One team. One point of contact. One warranty.
What You Manage
High-level decisions – what you want the space to do, how it should feel, your budget parameters. The firm handles everything from layout to final inspection.
What They Manage
Design development, permit applications, trade coordination, material sourcing, construction, and site supervision.
Cost Structure
Higher than straight-build GC, but comparable to hiring a separate designer ($3,000-$10,000+ in the GTA) plus a GC, with less friction and clearer accountability.
When design-build makes sense
- You have a vision but need professional help translating it into a real, buildable plan
- The project involves layout changes – moving walls, relocating plumbing, changing the footprint
- You want a seamless process where the people who designed it are the same people building it
- You’re doing a full kitchen or bathroom renovation and want everything designed before a single wall comes down
When it may be more than you need
- You already have complete drawings and a defined scope ready to tender
- The project is purely cosmetic – new paint, new hardware, surface finishes only
- Your budget genuinely doesn’t support the integrated overhead
Real-World Examples: Which Contractor Type Fits Which Project?
| Project | Best Fit | The Key Reason |
|---|---|---|
| Repainting two rooms + new light fixtures | Individual trade(s) | Single or two-trade scope, no sequencing complexity |
| Bathroom refresh – new tile, vanity, fixtures, same layout | Small GC or individual trades | Two to three trades, manageable if you’re organized |
| Full kitchen gut – new layout, electrical, plumbing, cabinets | General Contractor or Design-Build | Multi-trade, sequencing critical, permit likely required |
| Basement finishing – framing, electrical, egress window, flooring | General Contractor | Multi-trade, permit required in most GTA municipalities |
| Open-concept main floor – load-bearing wall removal, new kitchen | Design-Build | Structural changes require engineering + design integration |
| Whole second floor or full-home renovation | Design-Build | Complexity and design decisions too significant to separate |
A Practical Decision Checklist
Work through these before you start calling contractors.
About your project
- Does it involve more than two trades? (e.g., plumbing + electrical + millwork)
- Are you changing the layout – moving walls, relocating plumbing or electrical?
- Will active construction run longer than four to six weeks?
- Does it require a building permit? (In the GTA, most structural changes, electrical panel work, and plumbing relocations do)
About your availability and experience
- Can you be genuinely available on-site during business hours when needed?
- Have you coordinated multi-trade projects before and do you understand sequencing?
- Are you comfortable resolving problems quickly when two trades disagree or something doesn’t line up?
- Do you already have a defined scope and drawings – or do you need design help?

The One Thing That Doesn’t Change
Whichever route you choose, the contract is non-negotiable. A handshake agreement with a solo tiler leaves you just as exposed as a verbal understanding with a GC managing six subtrades. Written contracts aren’t bureaucracy – they’re the only thing that protects you when a timeline slips, a scope expands, or a dispute arises.
