Most renovation regrets — overspending, delays, disputes — trace back to skipped planning. Work through this checklist before you commit, and the build itself becomes far less stressful.
Decide your total budget and add a 10–15% contingency for surprises (old wiring, hidden leaks, variations). Size it with our cost calculator → and the renovation cost guide →. If financing, see renovation loans →.
| Contingency scenario | What it covers | Recommended buffer |
|---|---|---|
| Simple cosmetic job | Minor variations, small overruns | 10% |
| Full renovation | Hidden defects, plumbing surprises, scope additions | 12–15% |
| Older property (10+ years) | Outdated wiring, pipe replacement, waterproofing | 15–20% |
List exactly what you want done, and separate must-haves from nice-to-haves. A clear scope is what makes quotes comparable and stops budget creep. Common must-haves: kitchen, bathrooms, flooring, built-ins. Nice-to-haves: feature walls, smart lighting, premium fixtures.
A useful approach is to rank each item: priority 1 (non-negotiable), priority 2 (do if budget allows), priority 3 (nice-to-have but deferrable). If the quotes come in over budget, you can cut Priority 3 items without gutting the whole project. Give this ranked list to every contractor so their quotes are truly comparable.
Condo? Get management approval → and pay the deposit. This can take 1–3 weeks, so apply early — before the contractor starts. Structural or external work? Check council approval →. New unit? Claim developer defects → first.
Finalise layout, materials, colours, tiles, fittings and lighting before work starts. Mid-project changes are the top cause of delays and overruns. Prepare a materials schedule: every item, brand, model and colour code. Visit tile showrooms and cabinet suppliers to confirm stock availability — custom or imported items can have 4–8 week lead times. If an item is out of stock, better to know now than when the tiler is on-site waiting.
Never start on a handshake. Use a written, itemised contract — see contract guide → and the free contract checklist →. The contract must include scope, payment schedule, completion date and warranty terms.
Pay nothing significant before a signed, itemised contract is in hand. Once signed, a 10–20% mobilisation deposit is reasonable. Paying a large deposit before signing the contract is the most reliable way to lose money in a renovation. If a contractor insists on payment before paperwork, walk away.
| Factor to compare | What to look for |
|---|---|
| Scope | Same inclusions across all three quotes |
| Material spec | Brands named, not “standard” |
| Quantities | Realistic measurements, not under-counted |
| Payment terms | Progress-based, modest deposit |
| Timeline | Committed milestones, in writing |
| Warranty | Workmanship + waterproofing warranty stated |
Agree a written timeline with the contractor — stage by stage, with payment milestones. Build in buffer for approval times and long-lead materials. A condo full reno typically needs 6–10 weeks; a terrace house 8–14 weeks. See our renovation timeline guide → for stage-by-stage detail.
The timeline should also be realistic about your own availability: you need to be reachable for decisions, site visits and payment releases. Disappearing for a two-week holiday mid-project without a designated decision-maker can stall work just as much as any contractor delay. Agree in advance how decisions will be made and who signs off on milestone payments if you cannot visit in person.
