On most renovation projects the final figure is higher than the client originally planned. This isn't always the contractor's fault — often the budget wasn't planned realistically. Here's how to do it right.
Once you have the overall budget in place, if you want to know exactly what goes into an itemised quote, we cover that in this article.
Step 1: Define the scope of work
Before anyone quotes, you need to know: what exactly do you want done? Make a list: which rooms, what renovation level (cosmetic/mid-range/full), does the plumbing stay, are windows being replaced? The more precise the scope, the more accurate the price.
Step 2: Get an itemised quote
Don't accept a "per m²" price without discussion. An itemised Excel quote shows you exactly what you're paying for. No line items = no transparency.
Step 3: Plan a contingency
Every renovation can reveal hidden problems: old pipes, moisture, poor floor base. Always plan at least 15–20% contingency on top of the main cost. Those who don't typically panic at the first unexpected item.
Step 4: Prioritise
If budget is limited, decide: what you must not cut corners on (plumbing, electrical, waterproofing), and where you can (surface finishes, furniture, decor). Never compromise on structural or mechanical work quality.
Step 5: Fixed price in the contract
The only way your budget is actually a budget: fixed price in the contract. No surprises at final invoice. At ConSol we guarantee this on every project.
Frequently asked questions
Total cost: labour + materials + contractor coordination fee + permit costs (if applicable) + contingency (15–20%). Most people forget the last two items.
Recommended: 20–30% deposit at start, milestone payments (e.g. plumbing done, tiling done), and 10–20% at handover. Never pay everything upfront.
Yes — a bank personal loan, government subsidy programmes (if the property qualifies), or a payment schedule agreed with the contractor. Worth discussing before the project starts.
