General contractors in Whitby typically charge 10 to 20 percent of total project cost as their management fee, or an hourly rate of $75 to $150 for smaller scopes. For a full home renovation, budget $100 to $300 per square foot depending on finishes and complexity. Always get a fixed-price or detailed cost-plus contract in writing before any work begins.
A general contractor manages the entire renovation or construction project: hiring and scheduling subcontractors (plumbers, electricians, framers, etc.), obtaining permits, ordering materials, and ensuring work meets building code. On larger projects they act as the single point of contact, which saves homeowners significant time and coordination effort.
Look for a contractor with a solid local reputation, verifiable references from completed projects in Whitby, and a portfolio of similar work. Confirm they carry general liability insurance and WCB/WSIB coverage for all workers on site. A written contract specifying scope, timeline, payment schedule, and change-order procedures is non-negotiable on any project over $5,000.
A kitchen renovation typically takes four to eight weeks. A full bathroom renovation runs three to six weeks. Whole-home renovations can take four to twelve months depending on scope and permit timelines. In Whitby, permit processing times vary by season and can add two to six weeks to a project schedule. Ask your contractor to build permit time into the project timeline.
Most structural changes, additions, electrical upgrades, plumbing rough-in changes, and work that affects the building envelope require a permit in Whitby. Cosmetic work such as painting, flooring replacement, and cabinet swaps generally does not. Your contractor should obtain all required permits before work begins. Building without permits can result in fines and complications when selling.
