What a general contractor actually does

Managing a renovation is a full-time job. Most homeowners find that out the hard way.

A general contractor takes legal and operational responsibility for an entire project. That means pulling all permits in the GC's name, hiring and coordinating all subcontractors, managing the construction schedule, holding the primary insurance and WSIB coverage for the job site, and owning the outcome when something goes wrong between trades.

When you hire a GC, you are not paying for convenience. You are buying a single point of accountability. If the plumber runs behind and it holds up the drywaller, that is the GC's problem to solve, not yours. If the framing inspection fails, the GC fixes it and re-books, not you. If a subcontractor does not show up, the GC is on the phone before you even know there was an issue.

BB Carpentry operates as a licensed GC on every project we take on in Cambridge, Kitchener and Waterloo. Brad manages every trade, every inspection, and every supplier from the planning call through to occupancy. You deal with one person throughout. That is not how every contractor works. It is how we work.

One Call
You contact Brad. He handles the plumber, the electrician, the drywaller, the tile setter. All of it. You never manage a subcontractor directly.
One Contract
A single agreement between you and BB Carpentry. Not a stack of contracts with individual trades, each with their own liability limitations and payment terms.
One Person Accountable
If something goes wrong, Brad owns it. Not a tradesperson you have never met. The person who shook your hand at the planning call is the person responsible for the outcome.
The GC role in detail

What Brad manages on every project in Waterloo Region

01

Trade Hiring and Coordination

Every subcontractor on your project is hired, vetted, and managed by Brad. Plumbers, electricians, HVAC technicians, tile setters, drywall crews, painters — all sourced from a network of trades Brad works with regularly across Cambridge, Kitchener and Waterloo. You never interview a plumber. You never chase a callback. You never coordinate two trades who need to be in the same room on the same day.

02

Permit Applications and Inspections

Permits are applied for in BB Carpentry's name, with BB Carpentry listed as the GC of record. We prepare the full application package, submit to the City of Cambridge, Kitchener, or Waterloo, and manage all required building inspections throughout construction. When an inspector requires a revision, we handle it. Construction does not begin until the permit is in hand.

03

Schedule and Sequencing

Renovation scheduling is more complex than it looks. Trades have to enter the site in the right sequence, and each one has to be done before the next can begin. A delay at framing pushes plumbing rough-in, which pushes electrical, which pushes insulation, which pushes drywall. Managing that chain is the GC's job, not the homeowner's. We build and maintain the schedule from day one and communicate any changes in writing before they affect your timeline.

04

Insurance, WSIB, and Liability

When BB Carpentry operates as GC on your project, we carry the primary general liability insurance and WSIB coverage for the site. Every subcontractor we engage carries their own insurance as well, and we verify that coverage before they set foot on your property. As a homeowner, you are not exposed to the liability that comes with managing trades directly on your property without proper coverage in place.

The Complete Renovation Standard governs how we plan, design, specify finishes, install infrastructure, build for longevity, hold trades accountable, and communicate with you throughout. Seven pillars, enforced without exception on every project we take on as GC. It is the operational backbone of what one point of contact actually means in practice.

Common questions

General contractor questions answered

A general contractor takes full legal and operational responsibility for a project as a single party. That means pulling all permits in the GC's name, hiring and managing all subcontractors, carrying primary site insurance and WSIB, and being the single accountable party if something goes wrong. A renovation contractor who is not operating as a GC may do some of the work but often leaves the homeowner to hire other trades, manage permit applications, and carry liability exposure for unverified subcontractors working on their property. The distinction matters most when things go wrong between trades, which is when most renovation disputes happen.
Yes. Brad Bonnell Carpentry Inc. operates as a licensed general contractor and is registered as a corporation in Ontario. We carry full general liability insurance and WSIB coverage on every project, and we pull all required building permits in BB Carpentry's name as the GC of record. Documentation is available upon request at any time.
Sometimes on paper, rarely in practice. When you manage trades yourself, you absorb costs that are easy to underestimate: time spent sourcing, vetting, and negotiating with each trade; delays caused by sequencing errors you did not know to avoid; rework required when one trade damages or undermines another's work; and legal exposure when an uninsured subcontractor is injured on your property. GC fees typically run 15 to 25 percent of construction cost. Most homeowners who self-manage a project of any significant scope spend more than that covering mistakes and delays that an experienced GC would have prevented.
Every subcontractor on a BB Carpentry project is required to meet our technical and behavioural standards before being engaged. Work is inspected and signed off at every trade handoff before the next trade takes over the site, using a documented bilateral handoff protocol that eliminates the most common cross-trade dispute: "that was already like that when I got here." We verify trade insurance before they arrive on site, and we are on the project throughout construction, not available by phone from another job.
The first step is a free planning call. You describe the project, Brad asks questions, and you get an honest read on scope, timeline, and rough budget before committing to anything. If it is a good fit, we move into the planning phase where all selections are finalized, permits are applied for, and the budget is locked before construction begins. The call takes about 20 minutes and there is no obligation. You can book through the contact form or call (226) 696-0555 directly.
