How to Read a Renovation Quotation
Three quotations for the same bathroom: RM18,000, RM24,500 and RM31,000. Which contractor is expensive? The honest answer is that you cannot tell from the totals — only from the lines. Here is how to read them the way a quantity surveyor would.
Lump sums hide; measured items reveal
"Bathroom renovation — RM18,000" tells you nothing. A proper quote breaks the same work into demolition, waterproofing (with the system named), tiling (with size, grade and laying pattern), plumbing points, sanitary ware supply, electrical points and hauling. When items are measured — square metres of tiling, number of points — you can compare quotes line against line.
Provisional sums are placeholders, not prices
A provisional sum (often marked "PS") is an allowance for work that cannot be priced yet — say, "PS: RM2,000 for concealed pipe replacement if found corroded". It is legitimate, but ask two questions: what triggers it, and will unused amounts be credited back? A quote stuffed with provisional sums is really an estimate wearing a quote's clothes.
PC rates cap the material, not the work
A prime cost (PC) rate like "tiles: PC RM5.50/sq ft" means the labour is included but the tile itself is budgeted at that rate — pick a RM9.00 tile and you top up the difference. Low PC rates are the oldest trick for producing an attractive total. Check whether the rates are realistic for the finishes you actually want.
Read the exclusions twice
The cheapest quote in our example excluded debris disposal, scaffolding and the plumbing reconnection — about RM4,000 of unavoidable cost that would have surfaced as variation orders. Common exclusions to watch for: permits, hoarding, protection of common areas, haulage above the second floor and touch-up painting.
Payment terms tell you about cash flow — theirs
Healthy contractors ask for a modest deposit and stage payments tied to completed milestones you can verify. Be careful with front-loaded schedules that collect most of the contract value before the wet works are even done; they usually signal a contractor financing an older project with your money.
