How to compare renovation quotations in Singapore, line by line

Three quotations for the same flat can differ by S$5,000 or more, and the cheapest one is often cheapest because something is missing. Here is a method you can do yourself in an evening.

1. Put every quotation into the same list of items

Quotations are written in each firm's own order and wording. Make one list of work items (hacking, masonry, tiling, waterproofing, carpentry, electrical, plumbing, painting, ceiling, glass, disposal, cleaning) and copy each firm's price into the right row. Where a firm gives one "package" price, write it once and mark the other rows as "inside package".

2. Compare quantities, not just prices

A tiling line means little without the area in m² and the tile allowance per m². Carpentry means little without the length in feet run and the material. If one quote says "kitchen cabinets S$3,600" and another says "14 ft top + bottom, plywood carcass, S$4,200", only the second can be compared. Ask the first for the missing quantities.

3. Look for the lines that are missing

Waterproofing for bathrooms: membrane, number of coats, ponding test, warranty.
Electrical work: number of power and lighting points, and who the licensed electrical worker is.
Permit and submissions: who applies for any HDB renovation permit.
Disposal and protection of lifts and corridors.
Final cleaning, and touch-up after defects.

An item that one firm includes and another omits is not a saving; it usually comes back later as a variation order.

4. Read the payment terms as carefully as the prices

Check how much is asked at signing and what each later payment is tied to. A schedule tied to completed stages keeps the amount you have prepaid close to the work actually done. See our guide on deposits and progress payments.

5. Check the basics for HDB flats

HDB says flat owners should only engage contractors listed in its Directory of Renovation Contractors, and some works need a renovation permit. Ask each firm for its listing and who applies for the permit, then check on HDB's site. HDB: important information on renovations

6. Turn the gaps into questions

Write one short message per firm listing exactly what is missing or unclear. Firms that answer clearly and in writing are easier to hold to their quote.
