A lump sum tells you nothing
Picture two quotations on your table for the same house. Both list kitchen cabinets, tiling, electrical work and painting. Both contractors seemed competent on the site visit. One quote totals RM90,000. The other totals RM150,000.
The instinct is to ask which contractor is overcharging. The better question is what each of them is actually pricing, and you can only answer that if the quote lets you see.
"Renovation works: RM85,000" is a number, not a quotation. A real one breaks the total into lines you can check: carpentry priced per foot run, tiling per square foot, painting by area or by room, and electrical points counted and priced one by one, each with its own quantity and rate. FindContractor's 2026 guide is blunter still: a lump sum is only acceptable for very minor works, under about RM2,000, where the scope is crystal clear. If you can't see where a price comes from, you can't judge whether it's fair, and you certainly can't compare it with a second quote.
The material grade behind the line, not just the category
Once a quote is itemised, read the words before the numbers. Take "quartz countertop". FindContractor's example is a local quartz brand at around RM180 per sq ft against imported Caesarstone at around RM350. Same item on paper, nearly double the price.
Cabinets work the same way. "Kitchen cabinets: RM18,000" could mean melamine-faced board with basic hinges, or plywood with soft-close hardware, and the line reads identically on both quotes. A proper quotation names the board type, the hardware brand and the finish, not just "cabinets". Our kitchen renovation cost guide has the per-foot prices for each.
Why two quotes for the same house can differ by RM60,000
Back to the two quotes on your table. On a whole-house renovation, a RM60,000 gap is rarely one contractor simply working for less. It's usually two contractors pricing different jobs under the same headings. Malaysian guides point to the same culprits again and again: different assumptions about hacking, wet works, plumbing, electrical points, carpentry, finishes, protection work and waste disposal.
So the cheaper quote may have left out the rewiring and the waterproofing that the dearer one included. Those items don't vanish. They come back as variation orders, priced after you've signed and the crew is already on site. Margin plays a part too, since one guide calls a 15 to 30 percent markup on supplied materials normal, but margin alone rarely explains a gap that size. iHome's 2026 guide puts it plainly: a price far below the others is usually a price that will be "revised" mid-project. Compare the specification line by line, not the total at the bottom.
A quote that's 30 percent cheaper is rarely the same renovation at a discount. More often it's less renovation, or a price that changes once work starts. Plan your renovation and every item in our quotation is explained, not just listed.
What cheap quotes usually leave out
When you go looking for the missing money, these are the lines to check first.
- Preliminaries. Disposal, site protection and cleanup. Hacking and disposal alone can run RM1,500 to RM5,000, and none of it disappears because a quote leaves it out.
- Contingency. An allowance for what an old wall or old wiring reveals once it's opened up. Guides suggest holding 10 to 15 percent aside. Leaving it out doesn't mean nothing will be found. It means you'll be quoted for it mid-project instead.
- Supporting M&E work. New lighting or appliances often need new or moved electrical points, each adding a few hundred ringgit, which a cabinet-only quote never mentions.
- Waterproofing. Easy to leave off a wet-area quote because it's invisible once tiled over, and expensive to fix afterwards. Our bathroom renovation cost guide explains why it's the line that matters most.
Questions worth asking before you sign
You don't need to be a quantity surveyor to read a quote well. You need two or three quotations, the same questions put to every contractor, and the answers in writing.
- What board or material grade sits behind each carpentry line, specifically?
- Are disposal, protection and contingency included, or billed separately later?
- What happens if hacking reveals a problem the quote didn't anticipate, and how will that variation be priced?
- What's excluded? A good quote lists its exclusions as clearly as its inclusions.
- Is the payment schedule tied to completed work stages, or a flat deposit and balance? See our contractor deposit and payment schedule guide for what a fair schedule looks like.
- How long is the price valid? Quotations are commonly valid for 14 to 30 days, after which prices can move.
Put those questions to the RM90,000 quote and the RM150,000 quote, and they usually stop being two prices for one job. They become two different jobs, and you can choose the one you actually want. It's why every quotation we issue explains what each item is for, not just its price: a homeowner who understands their own quote makes better decisions than one who's asked to trust it blindly.
