How to Get Accurate Contractor Estimates

Start With Research, Not a Phone Call

The biggest mistake homeowners make is calling contractors before they know what a fair price looks like. Use a cost calculator to establish your expected range before making a single call. If a contractor quotes 40% above that range, ask why.

Always Get Three Quotes

Three quotes give you enough data to spot outliers. The lowest quote isn’t always the best — it may indicate cut corners, unlicensed work, or a contractor who will hit you with add-ons later.

What to Include in Your Quote Request

• Specific project scope in writing (materials, dimensions, brand specs)
• Request itemized breakdown (materials separate from labor)
• Ask about permit costs — these should be included
• Confirm who does the work (contractor vs. subcontractors)

Red Flags in a Contractor Quote

• Quote given verbally with no written breakdown
• Requires large upfront payment (more than 30%)
• Cannot provide proof of license or insurance on request
• Pressure tactics (“this price is only good today”)
