how is this scored?

The Zhun Score starts at 100 and loses points for pricing above benchmark (weighted by dollar impact), contract red flags by severity, and genuinely missing scope. Exclusions you declared don't count against it. Verdicts themselves are computed mechanically against the rate database — see the methodology.

restructure the payment schedule

The current schedule collects 95% of S$55,000 — S$52,250 — before handover, leaving only S$2,750 (5%) as retention. That gives you almost no leverage if defects appear at completion. A 15% retention held until satisfactory handover is standard practice on a full HDB resale reno.

reduce storage cabinet rate to benchmark

The 14.5 ft full-height storage/shoe cabinet is quoted at S$360/ft run. The benchmark high is S$330/ft run and the median is S$280/ft run. At S$360/ft run the line is S$435 above the benchmark ceiling and S$1,160 above median on this run alone. The specs (PVC carcass, ABS trimming, Blum hinges) are standard — no premium material justifies top-of-band-plus pricing here.

confirm GST treatment in writing

GST is not stated anywhere in this quote. At 9%, GST on S$55,000 is S$4,950. If the quote is GST-exclusive, the true project cost is S$59,950. You need this confirmed before signing so the payment schedule and total are unambiguous.

the fine print, translated 🔓 full audit

The clauses and terms that deserve attention, in plain terms — the pricing story lives in the drill-down above; how to act on all of it lives in your negotiation kit below.

95% payable before handover — only 5% retention

S$5,500
why this matters

The payment schedule is 10% on confirmation + 45% on commencement + 40% on commencement of carpentry + 5% on handover. Cumulatively, 95% of S$55,000 (S$52,250) is payable before you receive the keys. Industry practice for a full HDB resale reno is to retain at least 10–15% until satisfactory handover. With only S$2,750 held back, you have minimal financial leverage to compel defect rectification.

GST not stated — potential S$4,950 surprise

S$4,950
why this matters

Neither the line items nor the project total make any reference to GST. At the current rate of 9%, if this quote is GST-exclusive the true cost is S$59,950. This ambiguity must be resolved before signing — a payment schedule built on S$55,000 becomes incorrect if GST is added later.

Laminate cap at S$60/pc — excess charged separately

why this matters

A footnote states: 'All cabinet laminate must not exceed $60 per piece. Any excess cost will be charged separately.' This is a material price cap that converts any laminate selection above S$60/pc into an automatic variation order. Given that the quote covers wardrobes, kitchen cabinets, storage cabinets, and a headboard panel — a large laminate area — even a modest overage per piece across multiple cabinets can add hundreds of dollars. You will not know the final cost until you select materials.

Provisional tile spec — 'tiles up to $5' is a VO seed

why this matters

The foyer tile line (est. 56 sqft, S$952) carries a provisional spec: 'Tiles up to $5.' Any tile selection above S$5/pc will trigger an additional charge. The quantity (56 sqft) and the 10% wastage allowance are already estimated, so the only variable is the tile unit cost — but that variable is uncapped on the upside.

No quote validity period stated

why this matters

The quote carries no expiry date. Without a validity period, the contractor is not bound to honour these prices if material costs rise or if you take time to compare quotes. A validity of at least 14 days is standard; 30 days is reasonable for a full-reno quote of this complexity.

5 make-good lines — consider consolidating

why this matters

There are five separate make-good lines across the quote (service yard bi-fold door, DB cabinet/skirting, bedroom 3 wall, common bedroom 2 door frame/skirting, master bedroom door frame/skirting), each priced individually. While each line is within the benchmark band, having five separate make-good items makes it harder to verify scope overlap and creates multiple small variation-order entry points if additional damage is found during hacking. Consolidating into one or two make-good allowances with a defined scope gives cleaner cost control.

Wall-mount shelving spec 'TBC' — material unconfirmed

why this matters

The master bedroom headboard line includes '2 sets wall mount shelving for side table (TBC using stainless steel materials).' The 'TBC' tag means the material — and therefore the cost — is not yet confirmed. This is a provisional item that will likely be resolved via a variation order once the material is chosen.

your negotiation kit 🔓 full audit

The full ask list — the top three mirror the game plan, the rest are grouped by what they touch. Tick the points you want to raise; the email is written from exactly the ticked list.

the full ask

The current schedule (10/45/40/5) collects S$52,250 — 95% of the contract sum — before handover. Request a revised schedule of 10/40/35/15, holding S$8,250 (15%) until satisfactory handover and written sign-off of all defects. This is the single most important structural protection in any reno contract.

the full ask

The 14.5 ft full-height storage/shoe cabinet (Living area) is quoted at S$360/ft run. The benchmark for full-height storage cabinets is S$220–330/ft run (median S$280). The specs — PVC carcass, ABS trimming, Blum hinges, E0 boards — are standard and do not justify above-range pricing. Request a reduction to S$300/ft run (median), reducing this line from S$5,220 to S$4,350, a saving of S$870. If the rate above S$330 is maintained, ask for a written breakdown of what drives the premium.

the full ask

GST is not mentioned anywhere in the quote or footnotes. At 9%, if the S$55,000 total is GST-exclusive, the true cost is S$59,950 — a S$4,950 difference. Before signing, require the contract to state clearly whether the project total is GST-inclusive or GST-exclusive, with the GST amount shown as a separate line item. Tie the payment schedule amounts to the GST-inclusive figure.

contract terms

the full ask

No validity period is stated. Without one, prices are not guaranteed while you take time to review or compare. Request a minimum 30-day validity from the quote date, written into the contract.

the full ask

There are five separate make-good lines totalling S$2,260. While each is within the benchmark band, multiple discrete make-good items create multiple variation-order entry points if additional damage is found during hacking. Request consolidation into one or two make-good allowances with a not-to-exceed (NTE) cap, and require any additional make-good to be agreed in a written, signed change order — with the price confirmed — before work proceeds.

scope & allowances

the full ask

The footnote caps laminate at S$60/pc, with any excess charged separately. Before signing, request a physical sample board of all laminates available within the S$60/pc cap for every cabinet run (kitchen, wardrobes, storage, headboard). If your preferred finishes exceed the cap, negotiate a higher fixed allowance per cabinet run — written into the contract — so the total cost is known before works begin.

the full ask

The foyer tile line (56 sqft, S$952) carries a provisional 'tiles up to $5' spec. Select the tile and confirm its unit cost before signing. If the chosen tile exceeds S$5/pc, negotiate a fixed per-sqft allowance with a written cap on any excess, rather than leaving it open-ended.

the full ask

Four door frames are hacked (master bedroom, common bedroom 2, master bathroom, common bathroom) but no new door supply-and-install lines appear in the quote. The benchmark for bedroom/toilet door supply and installation is S$340–650 each. Confirm whether new doors are included, and if so, add them as priced line items before signing to avoid a variation order mid-project.

the full ask

No waterproofing membrane or re-waterproofing line appears for either bathroom, despite fixture replacement and tile-adjacent works in both. HDB requires waterproofing when bathroom surfaces are disturbed. Confirm in writing whether waterproofing is included in the existing bathroom lines, or request it be added as a priced line item before signing.

the full ask

The master bedroom headboard incorporates 2 sets of wall-mount shelving at S$180/set, with material marked 'TBC using stainless steel materials.' Confirm the material and fix the price in the contract before signing. If the material changes, the price must be agreed in writing before fabrication — not via a verbal variation order on site.

variation order (VO)

Extra work added mid-reno, billed on top of your contract. Most budget blowouts live here — which is why we flag every gap that could become one.

retention

Money you hold back until defects are fixed after handover. Industry practice is 10–15% — it's your only leverage once works are done.

provisional sum

A placeholder price that can change once materials are chosen. Fine if capped — risky if open-ended.
