Three contractors, three wildly different prices, and no obvious way to tell which is the good deal. That's the normal experience — and it's almost always a scope problem, not a pricing problem. Here's how to get quotes you can actually compare.
Write the scope before you call anyone
The reason bids come back all over the map is that each contractor is quietly guessing at what you want. One assumes mid-grade fixtures, another assumes you're supplying them, a third includes demolition and disposal that the others left out. Fix this by writing a clear, itemised scope of work before the first call, and giving the same document to every bidder.
Your scope should spell out what's included, what you're supplying, and the finish level. Use the calculators to attach real quantities — "approximately 340 sq ft of flooring" or "roughly 2 tons of cooling" — so contractors are pricing against your numbers, not their guesses. The flooring, tile and HVAC sizing calculators are especially useful here.
Get at least three bids. Two isn't enough to see the middle. Three tells you the realistic market rate and flags the outlier — whether that's someone cutting corners on the low end or padding on the high end.
Make the bids apples-to-apples
Ask every contractor to quote against your line items in the same order. When all three quotes list the same scope broken out the same way, differences jump off the page: maybe one priced premium tile, or included the permit, or added a line for unforeseen repairs. You're no longer comparing three mystery totals — you're comparing decisions.
Read past the bottom-line number
The total is the least useful part of a quote. What you're really evaluating:
- Scope match — does it cover everything you asked for, or has something been quietly dropped to hit a lower number?
- Materials allowance — are fixtures and finishes specified, or hidden behind a vague "allowance" that balloons later?
- Labour vs materials split — a transparent breakdown is a good sign; one lump sum with no detail is a red flag.
- Payment schedule — reasonable is a deposit plus progress payments tied to milestones. Be wary of anyone wanting most of it up front.
- Timeline and change orders — how are delays and mid-job changes priced? Get it in writing.
- Licence, insurance and references — non-negotiable. Verify them, and actually call a past client.
Why the cheapest bid usually isn't
A quote well below the others is rarely a bargain. It usually means missing scope, a thinner materials allowance, or optimism about how smoothly the job will go — and the gap reappears as change orders once you're committed. Look hard at what the low bid doesn't include. Often the "expensive" middle quote is the honest one.
Keep everything in one place
By the time you've collected three quotes, each with a dozen line items, comparing them in your head is hopeless. Line them up side by side, item for item, so the trade-offs are visible. The Home Renovation Project Manager includes a contractor quote comparison built for exactly this — drop each bid in and see, per line, who's cheapest, what's included, and where the real difference lies.
The short version
- Write and share one clear scope with quantities from the calculators.
- Get at least three bids against that same scope.
- Compare line by line, not total to total.
- Read materials allowances, payment terms and timelines closely.
- Treat the lowest bid with the most suspicion.
- Verify licence, insurance and references before you sign.
