What is a reasonable range of quotes for similar work?

For Ottawa contractors, a reasonable range between quotes for similar work is typically 15-25%, though this can vary significantly based on the type and complexity of your project.

When you're getting quotes from licensed contractors in Ottawa, here's what to expect for quote variations:

Normal Quote Ranges by Project Type

Smaller projects (under $10,000) like bathroom updates or minor electrical work often see the tightest ranges - usually within 10-20% of each other when comparing apples-to-apples from properly licensed contractors.

Mid-size renovations ($10,000-$50,000) such as full bathroom or kitchen renovations typically see 20-30% variation. In Ottawa's current market, a bathroom renovation might range from $25,000 to $35,000 for similar scope, reflecting different contractor overhead, material sourcing, and scheduling.

Large projects ($50,000+) like additions or secondary dwelling units can see 30-50% variation, especially when dealing with Ottawa's permit requirements and structural complexities. A basement apartment conversion might range from $80,000 to $120,000 depending on the contractor's approach to meeting City of Ottawa secondary suite requirements.

Red Flags in Quote Variations

Quotes significantly lower (40%+ below others) often indicate corners being cut on permits, insurance, or quality. In Ottawa, be especially wary if a contractor suggests skipping City of Ottawa building permits (613-580-2424) or using non-ESA licensed electricians.

Quotes significantly higher (50%+ above others) may indicate premium positioning, but verify the value - are they including better materials, longer warranties, or more comprehensive permit handling?

What Creates Legitimate Price Differences

Permit and inspection handling - Some contractors include all City of Ottawa permit fees and inspections in their quote, others add these as extras. ESA electrical permits alone can add $200-500 to a project.

Insurance and WSIB coverage - Properly insured contractors with current WSIB clearance certificates cost more but protect you from liability. Verify coverage at wsib.ca/clearances.

Material sourcing and warranties - Established Ottawa contractors often have better supplier relationships, affecting both cost and quality.

Timeline and availability - Busy, reputable contractors may charge premium rates, especially during Ottawa's peak construction season (May-October).

Getting Comparable Quotes

Ensure all quotes include the same scope, materials, permits, and timeline. Ask each contractor to specify what permits they'll obtain through ottawa.ca/building and whether ESA/TSSA inspections are included.

For major projects requiring structural work, verify each contractor's approach to Ontario Building Code compliance - different interpretations can significantly affect cost.

If quotes vary dramatically, ask detailed questions about what's included and verify each contractor's licensing through ESA (esasafe.com) for electrical work or TSSA (tssa.org) for gas/HVAC components.

Remember, the lowest quote isn't always the best value, especially when dealing with Ottawa's specific permit requirements and seasonal construction challenges.
