How to Plan a Home Renovation Without Blowing the Budget

Most renovation overruns are not caused by expensive materials. They are caused by decisions made in the wrong order.

Decide the scope before you price anything

Table of Contents

The single most expensive habit in home renovation is pricing individual items before you have agreed the scope of the whole job. You end up comparing a quote for tiling against a quote for tiling plus levelling plus waterproofing, deciding the first one is better value, and finding out six weeks later why it was cheaper. Write down every room you are touching, what “finished” means for each one, and only then start collecting numbers.

Build the contingency into the plan, not the hope

Set aside 15% of the total on top of every quote you have accepted. On older properties, make it 20%. This is not pessimism — once walls are opened, something is always different from what the drawing said. If you do not spend it, you have a bonus. If you have not budgeted it, you have a stalled project and a difficult conversation.

Sequence the work so nothing gets done twice

Wet work before dry, structural before cosmetic, anything that lives inside a wall before the wall is closed. Electrical and plumbing first-fix, then plastering, then flooring, then painting, then fittings. Every time you get this order wrong you pay for the same surface twice, and the second time you also pay for the damage.

Get three quotes and read the exclusions

The gap between quotes is rarely about profit margin. It is about what has been left out. Compare the exclusion lists line by line — waste removal, making good, materials supply, VAT or GST treatment — and the cheapest quote very often stops being the cheapest.

He writes the site’s home improvement, flooring and real estate coverage, and he is unusually stubborn about two things: publishing real numbers instead of vague ranges, and telling readers when the cheaper option is genuinely the better one. If a guide on this site says a job takes four days and costs a certain amount, it is because Lokesh has either done it or stood over someone who did. He also handles editorial partnerships and every guest post enquiry that comes through the site.
