HDB Renovation: getting quotes that truly differ
HDB Renovation quotes only make sense when you compare like with like. Most owners get three numbers that look different on price but were never built on the same brief, so the cheapest one often just left things out. If you brief three firms identically, you'll finally see where the real gaps are.
Why identical briefs matter for HDB Renovation
When you hand three contractors the same flat, the same drawings, and the same list of works, the quotes that come back become comparable. Without that common ground, you're not comparing prices — you're comparing apples and kueh. One quote might include hacking and debris removal, another might quietly exclude them, and you won't spot it until the bill arrives.
The whole point is to remove guesswork. A contractor can only price what you describe. If your brief is vague, each firm fills the gaps with their own assumptions, and those assumptions are where budgets blow up.
Build one brief document before you call anyone
Write it once, then send the exact same file to every firm. Cover the basics so nobody is working from memory.
- Floor plan and room sizes — a simple measured sketch or the official floor plan works.
- Scope list — hacking, tiling, carpentry, electrical, plumbing, painting, and what you're keeping as-is.
- Material notes — the laminate grade, tile size, and paint type you have in mind, not just "nice tiles".
- Fixtures and fittings — list what you'll supply yourself versus what the contractor provides.
- Your move-in deadline — so lead times on carpentry are priced honestly.
Keep the document short but complete. The goal is consistency, not length.
How to brief the three firms the same way
Follow a fixed sequence so every quote is built on the same foundation.
- Send the same PDF brief to all three, and ask them to quote strictly against it.
- Walk them through the flat on separate site visits, but say the same things each time. Point at the same walls, the same toilet, the same bomb shelter recess.
- Ask for itemised pricing with quantities, so a square metre is a square metre across all three.
- Request exclusions in writing — what is NOT included should be a stated list, not a silence.
- Set a return date so you're not comparing a rushed quote against a leisurely one.
When all three come back on the same brief, the differences start to tell a story. A firm that's S$8,000 lower might simply have omitted the feature wall and the kitchen backsplash you described.
Reading the quotes side by side
Put the three quotes into a simple spreadsheet. Line up each item and look for the gaps rather than the totals.
- Quantities — one firm quoting 40 square metres of tiling and another quoting 55 for the same flat is a red flag.
- Material specs — check that "laminate" means the same thickness and brand tier everywhere.
- Warranty and rework — some quotes fold a one-year warranty in, others charge for it later.
- Permit and inspection handling — confirm who applies for the HDB renovation permit and who pays the deposit.
Based on recent market observations, a 4-room BTO reno typically ranges from S$30k to S$50k, while a 5-room sits around S$40k to S$60k. Resale flats with more hacking and rewiring usually run higher, often S$50k to S$80k and up. Use those bands to sanity-check the quotes in front of you.
What a clear quote should make easy
A good quote lets you answer three questions without calling the firm. First, exactly what am I getting? Second, what's excluded? Third, what happens if something breaks? When three briefs are identical, the firm that answers those most cleanly is often the safer pick, even if they aren't the cheapest.
One more thing: make sure every firm you approach is a BCA-licensed contractor on HDB's Directory of Renovation Contractors. You can brief the world perfectly, but an unlicensed quote is a quote you shouldn't take.
Make the comparison work for your home
Getting quotes that truly differ takes a bit of discipline up front, but it pays back the moment you sign. You'll know your HDB Renovation budget rests on real numbers, not on hope. And when you're ready to fill the home with custom carpentry — the wardrobe, the kitchen cabinets, the TV console — having that clear, comparable brief means the carpentry quote slots in without nasty surprises. Spend an hour on the brief now and you'll save weeks of confusion later.
