General contracting is the umbrella over everything else we do: whole-home renovations, additions, structural work, design-build projects, and full project management on jobs that involve multiple rooms, multiple trades, and multiple months. When a project is too big, too interconnected, or too consequential to manage yourself — or to hand to a single-trade company hoping they'll figure out the rest — a general contractor is the answer.
This page is for homeowners planning something substantial: gutting and renovating a whole house, adding a second storey or rear addition, removing walls to open a main floor, or bringing a tired property up to modern standards top to bottom. It's also for anyone trying to decide whether they need a GC at all — so we'll cover that honestly, including when you don't.
BuildNRGY has operated as a general contractor across the Greater Toronto Area for over ten years, and this is the page where our full setup genuinely matters: an in-house crew across the core trades, our own millwork and fabrication shop, and project management that owns the schedule from permits to final walkthrough.
The title gets used loosely, so here's the real job description:
Permits and approvals. Drawings, building permit applications, Committee of Adjustment variances where a project needs them, and coordination with engineers for structural work. Every GTA municipality runs its own permit process with its own timelines; knowing how each one works is a real part of the value.
Coordinating all trades. Framers, plumbers, electricians, HVAC, insulators, drywallers, tilers, painters, and the specialty trades a specific project needs. The GC decides who's needed, in what order, and holds them to a quality standard. On our projects, most of those trades are our own crew — more on why that matters below.
Scheduling and sequencing. A renovation is a dependency chain: rough-ins can't start before framing, drywall can't close until inspections pass, counters can't be templated until cabinets are in. The GC's schedule is what turns forty individual tasks into a project with an end date. When something slips — a delayed window shipment, a failed inspection, a surprise inside a wall — resequencing around it is the GC's problem, not yours.
Single point of contact and accountability. You deal with one company, one contract, one person answering the phone. When something goes wrong on a self-managed job, the plumber blames the framer and the framer blames the drawings. With a GC, there's no one to point at — the GC owns the outcome.
Budget management. Tracking costs against the contract, pricing changes before they happen instead of after, and flagging decisions that have budget consequences while there's still time to choose differently.
Whole-home renovation. Gut and rebuild the interior — new layouts, new mechanical systems, new finishes throughout — within the existing structure. Common with older GTA housing stock: solid bones, but knob-and-tube wiring, galvanized plumbing, no insulation, and a 1960s floor plan. A whole-home reno modernizes everything at once, which is more efficient than renovating room by room over a decade because the disruptive systems work (electrical service upgrade, plumbing replacement, HVAC) happens once, with the walls open once.
Additions. Rear additions, side additions, and second-storey additions. These are structural projects from the ground up — footings, foundation, framing, tying the new roof into the old — plus the zoning layer: setbacks, lot coverage, height limits, and often a Committee of Adjustment application. Second-storey additions add the question of living in or vacating the house during the work; we plan the build around your honest answer.
Structural work. Removing load-bearing walls to open a main floor, installing steel beams, underpinning basements for height, and correcting sagging or improvised framing from past renovations. All of it engineered, permitted, and inspected — structural shortcuts are the one category of renovation mistake that gets more expensive every year it hides.
Design-build. Design and construction under one contract. Instead of hiring a designer, taking the drawings to bid, and discovering the design costs 40% more than your budget, design-build develops the design against the budget from day one. Decisions get made with a builder in the room saying "that detail is beautiful and here's what it costs — here's the version that gets you 90% of it for half."
Full project management. For projects with an outside architect or designer already attached, we take the drawings and run the build: permits, trades, schedule, budget, inspections, and communication.
Honest guidance, because a GC's overhead only makes sense when there's something to manage:
You likely don't need a GC when: the project is one trade or one room — flooring replacement, a painting job, a fence, a straightforward powder room. Hire the trade directly or a small renovator and save the management layer.
You need a GC when any of these are true:
The gray zone is the big single room — a kitchen or a full basement. Those still involve five-plus trades and inspections, which is why we run them with the same project management as a whole-home job. The difference between a good and bad kitchen renovation is usually management, not craftsmanship.
On a whole-home project, finish selections number in the hundreds — flooring, tile, cabinetry, counters, doors, trim profiles, hardware, paint, lighting, plumbing fixtures. Individual choices are covered in depth on our kitchen, bathroom, and basement pages; at the whole-home level, what matters is:
Consistency. Flooring that runs continuously, one trim profile, a coordinated hardware finish, and a controlled palette are what make a renovated house feel designed rather than assembled. We build a whole-home finish schedule early so every room's selections get made against the same plan.
Long-lead awareness. Windows, doors, custom cabinetry, and appliances can carry lead times of several weeks to a few months. On a multi-phase project, ordering is sequenced so no phase waits on a product that could have been ordered in month one.
Our own millwork and fabrication shop. On whole-home projects this stops being a nice-to-have and becomes a schedule and quality tool: kitchen cabinetry, bathroom vanities, built-in shelving, media walls, mudroom lockers, closet systems, and stair components can all come out of our shop — matched in species, finish, and profile across the whole house, built to the real dimensions of a house where nothing is square, and delivered on our schedule rather than a supplier's. When something needs adjusting on site, it goes back to our shop, not into a reorder queue.
Timelines, typically: a whole-home interior renovation runs 3–6 months of construction; additions run 4–8 months depending on size and season; and permits add their own phase before construction — commonly 1–3 months in GTA municipalities for straightforward permits, longer where a variance is needed. Anyone quoting a whole-home gut in six weeks is telling you something about their process.
Living in the house vs moving out. Single-floor phased work can be livable. Whole-home guts and second-storey additions usually aren't — no kitchen, no reliable bathroom, dust everywhere, trades from 8 a.m. Factor temporary housing into the real budget; pretending you'll live through a gut reno is the most commonly regretted planning decision we see.
Contingency is not optional. Older houses hide things: improvised past renovations, undersized framing, deteriorated drains. A realistic project carries a contingency — typically 10–15% of construction cost — and a GC who says you won't need one hasn't opened many walls. The difference between a stressful project and a managed one is whether surprises were budgeted for as a category, even though no one can name them in advance.
How to compare GC quotes. Line-by-line scope beats a single number. Check what's excluded (permits? engineering? disposal? HST?), what allowance figures are carried for finishes and whether they're realistic, and how change orders get priced. The lowest bid with vague allowances routinely finishes as the most expensive project.
Payment structure. Progress payments tied to completed milestones are the industry standard that protects both sides. Be cautious of large upfront deposits disproportionate to early-stage costs.
Common mistakes to avoid:
This is the page where our structure is the product, so here it is plainly. Most GCs are management companies — every trade on your job is a subcontractor, and your schedule is the intersection of six other companies' calendars. Our core trades are in-house: the same crews, job after job, working to one standard and one schedule that we control. Custom millwork comes from our own shop, which removes the single most common source of late-project delays. And after ten years of whole-home renovations, additions, and structural work across the GTA, the surprises inside old Toronto-area houses are mostly things we've opened a wall and found before — which shows up in your project as realistic quotes, honest contingencies, and fewer mid-project change orders.
