Ask three contractors for a marble polishing quote and you might get three very different numbers. The variation usually comes down to a handful of concrete factors — here's what to check before comparing quotes.
Marble polishing quotes in Singapore can vary widely between contractors. Here's a clear breakdown of what actually drives the price up or down.
Floor area is the starting point, but it's rarely the only variable. The condition of the marble matters just as much: a floor that only needs a light buff-and-polish costs meaningfully less than one with deep scratches, cracks, or old wax buildup that has to be stripped first. Contractors typically quote per square foot, but the number of polishing passes and grit stages needed to reach a good finish depends entirely on the starting condition.
The type of marble also plays a role. Softer, more porous marbles common in older flats may need extra sealing steps that harder, denser stone doesn't. Furniture and fixture density affects labour time too — a fully furnished living room takes longer to work around than an empty unit during renovation, and some contractors price this in separately.
Every quote should be assessed on-site, but this gives a general sense of how scope typically breaks down:
| Condition | Typical Process | Relative Cost |
|---|---|---|
| Light dullness, no damage | Buff & polish only | Lowest |
| Moderate scratches, minor etching | Honing + diamond polishing | Moderate |
| Deep scratches, cracks, old wax layers | Grinding, crack repair, re-polishing | Highest |
| Large open area, minimal furniture | Faster turnaround | Lower labour cost |
| Small, furniture-dense rooms | More manual, slower work | Higher labour cost |
Beyond the floor itself, ask whether the quote includes furniture moving, dust protection for adjoining rooms, and a post-polish sealant. These are sometimes bundled and sometimes charged separately, and they're the usual source of surprise costs after the job starts.
The most useful thing you can do before comparing quotes is to have every contractor assess the floor in person rather than quoting from photos alone. Etching and lippage are hard to judge accurately from pictures, and a quote based only on square footage without an on-site check is more likely to change once work begins.
It's also worth asking directly what's excluded — skirting, staircases, bathroom floors, and balcony marble are sometimes treated as separate line items. A slightly higher quote that's fully scoped upfront is usually better value than a lower one that grows once the crew arrives.
Most established contractors work on a deposit-plus-balance structure, with the balance due on satisfactory completion rather than full payment upfront. Be cautious of anyone asking for full payment before any work begins, particularly for larger jobs, since this removes your leverage if the finished result doesn't match what was quoted.
Timing your job can also affect cost indirectly — scheduling around a broader house move or renovation, when the unit is already partly empty of furniture, tends to reduce labour time and therefore cost compared to booking a one-off job in a fully furnished, lived-in home.
Not necessarily per square foot. Smaller, furniture-dense rooms often take longer per square foot because of the manual work involved navigating around fixtures, so a small bathroom can sometimes cost more per square foot than a large open living area.
It varies by contractor. Some bundle a sealant application as standard, others quote it as a separate add-on. Always ask specifically, since it changes both the total cost and how long the finish will last before needing attention again.
It's worth asking exactly what's included before assuming it's a bargain. A lower quote that excludes furniture moving, dust protection, or sealing can end up costing more once those are added, or may indicate a shorter process that skips steps.
