HDB Renovation: why cheap quotes cost more later
HDB Renovation has a hard truth: the lowest quote is rarely the cheapest in the end. A number that sits well below the rest usually hides thinner materials, rushed labour, or scope that quietly disappears. Pay a bit more upfront for honest work and you avoid the far bigger bill that comes from fixing someone else's shortcuts.
Where the low number comes from
A quote that looks too good is almost always missing something. The contractor is not magic, they are just trimming where you cannot see yet. Common places the saving is found:
- Cheaper boards and fittings that swell or chip within a year or two.
- Fewer man-hours, so edges are rushed and alignment slips.
- Excluded items buried in the fine print, billed later as "extras".
- Skipped prep like proper levelling, which fails once furniture lands on it.
Based on recent market observations, a 4-room BTO reno typically ranges from S$30k to S$50k. If one quote comes in at S$22k, ask what is not included before you celebrate.
The rework tax you did not budget
When a cheap job fails, you pay twice. The first bill was the discount; the second is the fix, and fixing is always pricier than doing it right the first time because someone has to undo the bad work first. A warped cabinet door means new carpentry plus removal plus reinstall. A leaky waterproofing job means hacking tiles you just paid for.
This is the part nobody puts in the brochure. The "saving" evaporates, and you also lose time, patience, and a few weekends you will never get back.
Material trade-offs that bite
Labour in Singapore is not cheap, so a suspiciously low quote leans hard on materials. A few examples of how that plays out:
- Low-grade laminate peels at the edges near the kitchen sink where steam gathers every day.
- Thin plywood carcasses sag under heavy pots, while a proper 9mm to 18mm board holds its shape.
- Basic hinges and runners that are not rated for daily use start to stick within months.
- Weak waterproofing membrane in the toilet lets water seep to the neighbour below, a dispute nobody wants.
None of these show up on day one. They show up at month eighteen, right after your warranty got vague.
Labour: you get the pace you pay for
A fair quote pays skilled trades a fair rate, and those trades take the time to measure twice and cut once. A rock-bottom quote often means overloaded crews jumping between jobs, so your site sits idle for days, then gets rushed to catch up. Rushed work is how crooked tile lines and gaps at the skirting happen.
The cost of delay is real too. Every week pushed back is another week of rent or storage, and that money comes straight out of your "saving".
How to judge a quote fairly
Cheap is not the enemy, unclear is. When quotes come in, compare them line by line, not just the bottom number:
- Check that the item counts match: same number of cabinets, same length of built-ins.
- Confirm the board thickness and laminate brand are stated, not just "carpentry provided".
- Look for what is excluded, because that is where the real cost hides.
- Favour itemised "Open Book" pricing, which CaseTrust requires for contracts from S$5,000 signed on or after 1 Oct 2024.
A slightly higher quote with everything spelled out beats a low one full of blanks. Spend the money once, spend it well, and your whole-house carpentry will still look right years from now instead of becoming the job you paid for twice.
