Most budget blowouts are not dramatic. They are a series of reasonable decisions that each add a little.
A kitchen quoted at $42,000 becomes $51,000 like this: the plumber finds older pipework that has to be replaced, the benchtop gets upgraded once you see it in person, and a late change to the island size means re-cutting cabinetry that was already made. None of those is unreasonable on its own. Together they are a 20% overrun.
Five things keep it from happening.
Get one written quote for everything, not five loose ones. A single itemised quote covering cabinetry, benchtop, plumbing, electrical and installation gives you one number to hold everyone to, including yourself.
Ask what is fixed and what is an allowance. A line that reads “tiles: allowance” is not a price, it is a placeholder. Ask what it assumes, and what happens if you choose something dearer.
Settle the layout before the quote, not during the build. Moving plumbing or taking out a wall is the biggest single cost driver there is. Decide it at the planning stage, not once trades are on site.
Choose your materials before demolition starts. Decisions made under time pressure, with the old kitchen already gone, tend to be the expensive ones.
Set aside a contingency on purpose. Around 10% turns a genuine surprise into a non-event instead of a crisis.
We give you one written quote covering the full scope before any trade sets foot in your kitchen, so you know what you are paying for and why. And if you already have a quote from someone else, send it to us and we will tell you what is in it.
