Your Carpentry Factory Visit: Eight Things to Check Before You Sign

Carpentry is usually the largest single line on a BTO renovation quote — roughly a third of a full budget, and the part you cannot rip out and redo cheaply in three years. It is also the part you are asked to buy from a photograph.

A carpentry factory visit closes that gap in an hour. Showrooms try to close it too, and they do it by showing you the finish. But a display cabinet has been assembled by the best installer in the company, levelled on a flat floor, and lit from above. It tells you almost nothing about what arrives at your flat.

Neither is a trick. They answer different questions — and only one is the question you are buying.

A factory floor tells you the rest, because the decisions are still visible. Here is what to look at, in the order the line runs. Bring this list to any factory — ours or anyone else’s.

Seven stations. A showroom only ever shows you the last one.

1. Ask to see a board cut open

Every quote lists a board type. Very few owners have ever seen one in section. Ask for an offcut of what your carcasses will be made from and look at the core.

Plywood shows layers; particleboard shows compressed chips; MDF shows a dense, even brown. None of these is automatically the right answer — they behave differently, cost differently, and hold a screw differently. What matters is that you can see what you are being sold, and that the same board is on the floor as on the quote. We went through emission grades and moisture resistance in Formaldehyde Isn’t a Myth. In a Singapore kitchen, where humidity is constant and a leaking bottle under the sink is a matter of time, the core is the part that decides whether a base cabinet survives year four.

2. Run a fingernail along an edge

Edge banding is the strip that seals the raw edge of a panel. Done on a machine, it is applied under heat and pressure, trimmed flush, and you cannot feel the joint. Done by hand with contact adhesive, you can feel a lip — and a lip is where moisture gets in.

Cross-section through a panel edge, exaggerated for clarity. Your fingernail finds this in two seconds.

This is the single fastest quality test in the building, it takes two seconds, and no salesperson can talk you out of what your finger just found.

3. Read the hardware boxes

Hinges and drawer runners are the parts that fail first, because they are the only parts that move. A quote that says “quality soft-close hinges” is telling you nothing. A box on a shelf has a brand and a cycle rating printed on it.

Ask which hinge and which runner are going into your job, then look for that box on the floor. Ask what happens in year three when one fails: is it a standard part they stock, or something that has to be sourced?

4. Watch the CNC drill a carcass

On a CNC line, hinge cups, shelf-pin holes and connector positions come straight from the drawing file. The machine puts them in the same place every time.

That is not a technology boast — it is the reason your wardrobe doors line up. When holes are marked and drilled by hand on site, the fitter compensates with packers and silicone, and you live with the gaps. Watching one panel go through the machine tells you which of those two worlds your flat is going to be in.

5. Find the moisture and sealing step

Ask where exposed edges get sealed, and what happens to the panels that will sit under a sink, beside a washing machine, or inside a household shelter. There should be a specific answer and a specific place on the line.

If the answer is vague, that is your answer. (For shelters specifically, we went through SCDF’s permitted and not-permitted list in detail — worth reading before anyone quotes you for one.)

6. Look for the QC bench

Somewhere between assembly and wrapping there should be a bench where batches are checked, counted and labelled against the job. If there is not one, the checking happens in your living room on installation day — which is how a two-day install becomes a two-week one while a missing panel is re-cut.

Ask how a batch is labelled. Good labelling means the installers unwrap things in the right order instead of opening everything at once and filling your flat with cardboard.

7. Ask who installs it

This question matters more than any specification. Does the company that built these cabinets also fit them, or does the job get handed to a sub-contractor at the door?

It decides who you call when a door drops in month seven, and whether the answer is “we will come” or “that is the installer’s part”. Our own answer is that design, fabrication and installation are the same team — which is also why running the trades together removes most of the finger-pointing from a renovation.

8. Ask to see the warranty paper

Not the sentence in the brochure — the actual document. Read what is covered, what counts as wear and tear, and what you have to do to keep it valid.

New HDB flats also come with HDB’s own one-year Defects Liability Period, which is separate and covers the building, not your carpentry. Knowing which is which before you sign saves an argument later.

Why we run an open house instead of answering this in a brochure

Because every point above is faster to see than to read. We run the factory floor every Saturday and Sunday, cap sessions at 40 people so you can actually hear the answers, and run a free shuttle from Woodlands NS9, Admiralty NS10 and Sembawang NS11. Lunch is on us, and you leave with a goodie bag, a $10 NTUC voucher and $1,000 in renovation cash vouchers.

If a contractor cannot show you a factory at all, that is an answer in itself.
