Every GTA homeowner faces the DIY vs. contractor decision. This thread covers honest analysis of where DIY saves money and where it costs more.
Where DIY Works
Painting (interior and exterior), landscaping, basic assembly, demolition (after asbestos test), and basic backsplash tile in low-stakes areas. These have low risk of expensive mistakes and no legal restrictions.
Where DIY Creates Bigger Costs
Electrical work (licensed EC required by law in Ontario). Structural changes (engineering required). Plumbing beyond fixture swap (permit required). Waterproofing (failed waterproofing is expensive to redo). Roofing (safety and warranty issues).
The Time Cost Analysis
A homeowner earning $75/hour professionally who spends 200 hours on a DIY kitchen to save $8,000 in labour has “earned” $40/hour for work they may find stressful. DIY makes sense when opportunity cost is lower than contractor rates OR when the work is genuinely enjoyable.
Ontario Legal Requirements
DIY electrical work beyond basic fixture swaps is illegal in Ontario without an ECO or permit. ESA inspections are required for all electrical permits. This is a safety rule, not a suggestion.
