You have a grouting quote in your hand — from us or from anyone else — and one question: is this number right? A grouting job is invisible on the day it finishes and only shows its true quality two years later, so the price alone tells you almost nothing. The quote's contents tell you everything. Here is how to read one, line by line, in about ten minutes. It works on any quote, including ours.
"Premium epoxy" is not a product. A checkable quote names the brand and the line: Mapei Kerapoxy, Ardex WA, Sika SikaCeram, Laticrete SpectraLOCK. Real epoxy is two or three parts mixed on site against a working time. If the material arrives ready-mixed in a tub, it is a single-part acrylic or urethane — a different material at a different fair price, whatever the label says. One trap worth knowing: Mapei makes both Flexcolor CQ (ready-mixed, not an epoxy) and Kerapoxy CQ (true two-part epoxy). The shared "CQ" confuses people every week.
For re-grouting, more than half the labour is removing the old grout — raked out to at least two-thirds of the joint depth so the new material bonds to the tile edges, not to old cement. A skim coat over failed grout looks identical on handover day and comes off in sheets within a year. This is the single most common way a cheap quote is cheap.
Grout is priced by metres of joint, and tile size decides how many metres hide in each square metre:
| Tile size | Joint per m² | 10 m² floor carries |
|---|---|---|
| 1200 × 600 mm | 2.5 m | 25 m |
| 600 × 600 mm | 3.3 m | 33 m |
| 300 × 300 mm | 6.7 m | 67 m |
| 150 × 50 mm kit-kat | 26.7 m | 267 m |
The same 10 m² floor holds two, three or eight times the work depending on the tile — which is why any quote produced without asking your tile size is a guess, and a guess can move later. Divide the quoted labour by your joint metres: fair epoxy re-grouting in Singapore lands roughly between $5 and $15 per metre of joint depending on what has to come out first. Far below that range, something in checks 1 or 2 is being skipped; far above it, ask what you are paying for.
The second most common source of a low number is scope. Read for what is missing:
Ask: "Is this figure fixed and complete for the areas listed — yes or no?"
Most of the trade offers 1–2 years — which expires just before badly done grout typically fails, between years one and three. A contractor confident in their removal depth and materials can put a longer number in writing. Whatever the number, it only counts if it is written on the quote with the company's registered entity name and UEN behind it, so you can check who actually stands behind the paper.
Reasonable in this trade: a deposit that roughly covers materials, with the balance on completion after you have walked the finished joints together. Be careful with large upfront payments to any contractor you have no history with — and equally, expect to pay something up front; epoxy is bought per job in your colour and cannot be reused elsewhere. A staged structure (one bathroom completed and inspected before the rest proceeds) is a fair ask that good contractors can accommodate.
Copy, paste, send to any contractor:
Six questions, one message. A good contractor answers all six without hesitating — and if a cheaper quote answers them the same way ours does, take it: that is a genuinely better price for the same work. What these questions protect you from is not a higher price. It is paying twice.
