How do I compare renovation quotes and choose a contractor without getting stung?

Question

Getting renovation quotes and they're all over the place — some vague, some suspiciously cheap. - How do I compare them like-for-like? - What should a proper quote itemise? - How do I judge a contractor on competence, not just price, and what are the red flags? Trying to pick the right contractor, not the cheapest number (this is evaluating QUOTES/competence — separate from avoiding overcharging once work starts). How do I choose well?

Short answer: you can't compare quotes that aren't quoting the same thing — so first make every contractor price the SAME detailed scope, then compare like-for-like, and judge on competence, not the headline number. A proper quote ITEMISES the work (not one lump sum): scope by area/trade, materials and specs (which tiles, which fittings, waterproofing system), what's included vs excluded, provisional sums for undecided items, timeline, payment stages, and who handles approvals/NOCs. The suspiciously cheap quote is almost always cheap because it's EXCLUDED the expensive/hidden work (waterproofing, making good, the better materials) — you'll pay for it later as "variations." Judge the contractor on their itemisation, questions, references, licence, and how they handle the hidden stuff — a good one prices the prep and protects you; a cheap vague one prices the dream and bills the reality.

Make them comparable first: - Write a clear scope (rooms, works, the spec you want) and give it to every contractor so they all quote the same thing. Otherwise you're comparing a full job to a stripped one.

What a proper quote itemises (red flags if missing): - Broken-down scope by area/trade — not a single lump sum. - Materials + specifications (which tiles/fittings/sanitaryware, which waterproofing system), and inclusions vs exclusions spelled out. - Provisional sums / allowances for anything undecided (so it's not a surprise later). - Timeline, payment stages tied to milestones, and who handles approvals/fit-out NOC. - The hidden/prep work priced — waterproofing, making good, protection, waste removal.

Judge competence, not just price: - Ask questions back — a good contractor interrogates your scope and raises the hidden issues (waterproofing, drainage, levels); a cheap one just says "yes, no problem." - Licence + references + recent similar jobs you can see/call. - How they handle variations (agreed in writing before doing extra work).

The red flags: - A quote far below the others — it's excluded the costly work; expect "variations" to bridge the gap. - Vague lump sums, no material specs, no waterproofing line, no exclusions, cash-only, no licence, pressure to start immediately.

Common mistake: choosing the lowest number and then being nickel-and-dimed by variations for everything the cheap quote left out — ending up dearer AND stressed. Scope it, get like-for-like itemised quotes, and pick a competent, licensed finishing and fit-out contractor on value, not the headline. What quote red flag caught someone out?

Writing one clear scope and making everyone quote it was the single best thing we did — suddenly the quotes were comparable and the "cheap" one was obviously cheap because it had left out waterproofing and half the making-good. The contractor who asked the most awkward questions up front (about the drain, the levels, the waterproofing) turned out to be the competent one; the one who breezily agreed to everything was the one who'd have hit us with variations. Itemised quote, specs named, exclusions listed. Lowest number is a trap if it's not the same job.

For our shop fit-out the payment-stages-tied-to-milestones point saved us — never pay big up front, tie it to completed stages so you keep leverage. And get variations agreed in writing BEFORE the extra work, or the final bill balloons. The vague one-line lump-sum quotes I now bin on sight; a real contractor itemises and names materials. Competence shows in the questions they ask and the references you can actually check. Cheapest-and-vaguest has cost me before; itemised-and-licensed hasn't. Scope it tightly and compare like-for-like.
