How to compare contractor quotes — and what to watch for before you sign.
Three quotes for the same renovation can range by 30% or more. The difference usually isn't one contractor being greedy — it's that each quote describes a slightly different project. Here's how to read them side by side.
The five parts every quote should show clearly.
A quote is only comparable if you can see what is included, what is assumed, and what is left out. These are the five categories to check on every quote.
- Scope of work
- Exactly what will be done. A strong scope names tasks, materials, finishes, and who is responsible for each step.
- Labour
- The cost of tradespeople and project management. Watch whether this is a fixed line item or an open-ended hourly rate.
- Materials
- Products, fixtures, and finishes. Quotes should specify the brand, model, or grade — not just 'tile' or 'cabinets'.
- Allowances
- Placeholder budgets for selections you haven't made yet. These are one of the biggest sources of cost overruns.
- Contingencies
- A reserve for unknown conditions. 5–10% is common for renovation work; 0% often means risk has been pushed onto you.
Red flags that mean a quote needs a closer look.
- One quote is dramatically lower than the others without a clear reason.
- Line items are grouped into a single lump sum with no breakdown.
- Allowances are missing, unusually low, or not described.
- Exclusions are buried in fine print or not listed at all.
- The quote uses vague language like 'builder's standard' or 'as required'.
- No contingency is included, even though demolition or old-home work is involved.
Questions to send your contractor before you decide.
The best protection is a short email that forces specifics. Copy any of these into your message.
“Can you break this lump-sum line into labour, materials, and subcontractor costs?”
“What selections are these allowances based on, and what happens if my choices cost more?”
“Which items are excluded, and who pays if they become necessary?”
“Is this a fixed price or an estimate that can change?”
“What does 'builder's standard' mean in this quote specifically?”
Frequently asked questions
Should I get three quotes before hiring a contractor?
Yes. Three quotes give you a market range and reveal whether one bidder is unusually high or low. The goal isn't to pick the cheapest — it's to understand what fair looks like for your specific scope.
Why do contractor quotes vary so much for the same project?
Quotes differ because contractors assume different scopes, materials, labour rates, risk allowances, and profit margins. A low quote may omit items another contractor included explicitly.
What is the most common mistake homeowners make when comparing quotes?
Comparing only the bottom-line total. Two quotes with the same total can cover very different work. Compare the scope, allowances, and exclusions line by line.
