About · Methodology
A price index, not a content site.
Most renovation "guides" online are written by people who have never priced a renovation. They google a number, paste it in, and run. This site is the opposite. Slow, specific, with the math shown. If you find an entry that's wrong, send me the quote — I'll fix it.
I worked as a quantity surveyor for a Subang-based design-and-build outfit from 2017 to 2024. My job was to take a contractor's scribble of a quote, break it into 60–90 line items, and tell the client where the markup was hiding.
The thing I noticed: the same client would have called eight people before me, googled "kos renovate rumah teres" sixteen times, and still arrived with completely wrong expectations. Not because they were lazy — because the information online was bad. Stock photos, round numbers, no methodology. So this is the version of that information that's actually useful.
Each price band on this site is built from at least three real itemised quotes for a comparable scope, collected during the past 90 days, in the Klang Valley. Where I have access to bank renovation loan disbursement records (anonymised), I cross-check.
When the spread between contractors is wider than ±15%, I split the band into "budget" and "premium" instead of averaging — averages hide more than they reveal.
- No "top 10 contractor" lists with affiliate kickbacks.
- No email gate before showing you the calculator.
- No price band invented on a Sunday afternoon to fill an article.
- No paid placements dressed up as recommendations.
- No emojis in headings, ever.
Where I do recommend a specific contractor (a Shah Alam design-and-build firm called BINA+), it's because I've sat in their office, read their quote templates, and watched their workshop. They don't pay me. If they ever start, this paragraph will say so.
