A lump sum tells you nothing
"Renovation works: RM85,000" is a number, not a quotation. A real one breaks that number into carpentry priced per foot run, tiling priced per square foot, painting priced per room, electrical points priced individually, each with its own quantity and rate. If you can't see where a price comes from, you can't tell whether it's fair, and you definitely can't compare it to a second quote.
The material grade behind the line, not just the category
"Kitchen cabinets: RM18,000" could mean entry-level melamine board or mid-range plywood with soft-close hardware, and the difference in what you're actually getting is significant even though the line reads identically on two different quotes. A proper quotation names the board type, the hardware brand, and the finish, not just "cabinets".
Why two quotes for the same house can differ by RM60,000
Almost never because one contractor is simply cheaper. Usually because the two quotes are pricing different scopes wearing the same job title. One may include electrical rewiring and waterproofing that the other has quietly left off, to be added later as a variation order once you've already committed. Compare the specification line by line, not the total at the bottom.
A quote that's 30% cheaper is usually 30% less renovation, not the same renovation at a discount. Plan your renovation and every item in our quotation is explained, not just listed.
What cheap quotes usually leave out
- Preliminaries. Disposal, site protection, cleanup. Real costs that don't disappear because a quote omits them.
- Contingency. A allowance for what an old wall or old wiring reveals once it's opened up. Skipping this 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 sometimes need electrical points a cabinet-only quote never mentions.
- Waterproofing. Easy to omit from a wet-area quote since it's invisible once tiled over, and expensive to fix after the fact.
Questions worth asking before you sign
- 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?
- 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.
Every quotation we issue explains what each item is for, not just a list of prices, because a homeowner who understands their own quote makes better decisions than one who's asked to trust it blindly.
