Questions to Ask Your Renovation Contractor Before Signing 2026
Before signing any renovation contract in Singapore, ask about total project cost breakdown, payment schedule (typical 30-20-20-20-10%), timeline with milestone dates, HDB/MCST permit responsibility, warranty terms (minimum 12 months), contractor license numbers (HDB/BCA), renovation insurance coverage, variation order process, and defect rectification procedures. Get everything in writing. A proper contractor gives you itemised quotations, not lump-sum estimates. Expect 6-10 weeks for HDB flats, 8-14 weeks for condos, and request fortnightly site progress reports.
Pricing and Payment Structure Questions
The first conversation with any contractor should dissect costs. Don't accept a single lump-sum figure. You need to know exactly where your money goes, because variation orders and surprise costs derail more projects than any other issue.
What's included in the quotation and what's excluded?
Ask for a detailed, line-item breakdown. Every reputable contractor itemises carpentry, hacking, electrical, plumbing, flooring, painting, and false ceiling separately. Excluded items usually include appliances, furniture not built-in, curtains, and sometimes lighting fixtures. At Larry Contractors, we list every component down to the brand and model of materials—no vague "as discussed" entries.
What's the payment schedule?
Standard Singapore practice follows a milestone-based structure. Avoid contractors demanding 50% or more upfront—it's a red flag. Here's the typical schedule:
| Payment Stage | Percentage | Trigger |
|---|---|---|
| Deposit | 30% | Upon contract signing |
| 2nd Payment | 20% | Hacking and structural work completed |
| 3rd Payment | 20% | Plumbing, electrical, carpentry framework done |
| 4th Payment | 20% | Flooring, painting, carpentry installation completed |
| Final Payment | 10% | Defects rectified, project handover |
How are variation orders priced?
Changes during renovation are common—you might want an extra cabinet or upgrade tiles. Ask upfront how variations are calculated. Ethical contractors price variations using the same rate card as your original quote, with transparent mark-ups (typically 15-25% on materials, labour at hourly rates of SGD 30-50 depending on trade). Get a written variation order before any additional work starts. No surprises at final payment.
What happens if the project goes over budget?
Confirm whether the quote is fixed-price or subject to adjustment. Fixed-price contracts protect you from cost overruns unless you request changes. If a contractor mentions "provisional sums" for items like hacking or electrical work, demand a maximum cap. Reputable firms absorb minor cost variations; you only pay more if you change the scope.
Timeline and Project Management Questions
Delays cost money and sanity. You need a realistic timeline with buffers, not optimistic promises. Singapore renovation timelines depend on property type, scope, and permit approval speed.
What's the realistic project duration?
Here are typical durations for common project types:
- HDB 3-room partial renovation: 4-6 weeks
- HDB 4-5 room full renovation: 6-10 weeks
- Condo 3-bedroom full renovation: 8-12 weeks
- Landed terrace full renovation: 10-16 weeks
- Commercial F&B fitout: 6-10 weeks (post-NEA approval)
Add 2-4 weeks for permit approvals if extensive hacking or structural changes are involved. HDB typically takes 7-14 days for approval; condos depend on MCST responsiveness (1-4 weeks).
Who applies for HDB/MCST/BCA permits?
This is critical. The contractor should handle all permit applications, not you. Ask specifically: Will you submit the HDB renovation application through the HDB online portal? Do you engage a PE (Professional Engineer) if needed for structural work? For condos, who liaises with the MCST and attends the site inspection? For landed properties requiring Addition & Alteration permits, is BCA submission included?
At Larry Contractors, we manage the entire permit process. You sign the forms; we do the running around. Our HDB license (HB-09-5667H) and BCA GB2 grading mean we handle this routinely.
What's the site supervision and reporting structure?
Ask how often the project manager visits the site. Daily supervision is standard for active phases (hacking, carpentry installation). Request fortnightly progress updates via WhatsApp photos or a shared folder. Confirm a single point of contact—you shouldn't be coordinating with five different tradesmen.
Licensing, Insurance, and Compliance Questions
Singapore regulates renovation work. An unlicensed contractor puts you at legal and financial risk. HDB can halt works, MCST can fine you, and you're liable for worksite accidents without proper insurance.
What licenses and registrations do you hold?
For HDB projects, the contractor must have a valid HDB license. Check the license number on HDB's registered contractors list. For condos and landed, BCA registration is important for track record, though not legally mandatory for minor works. Ask for:
- HDB license number and expiry date
- BCA grade and registration number
- ACRA business registration
- Any trade-specific certifications (e.g., licensed electricians, plumbers)
What insurance do you carry?
Two types matter: workmen's compensation insurance and public liability insurance. Workmen's comp covers injuries to workers on your site. Public liability covers damage to your property or neighbours' units (water leakage, structural damage). Ask for proof—a valid certificate of insurance with coverage of at least SGD 1 million for public liability. If the contractor can't produce this, walk away.
How do you ensure HDB renovation guidelines compliance?
HDB has strict rules: no hacking of bomb shelter walls, no removal of bedroom window grilles before TOP, hacking hours 9am-5pm weekdays, protective floor hoarding required. Ask how the contractor ensures compliance. Do they brief workers? Do they use the HDB renovation app for notifications? Non-compliance risks a stop-work order and delays your project by weeks.
Material Selection and Workmanship Questions
Vague material specs are the breeding ground for disappointment. "Homogeneous tiles" could mean anything from SGD 3 to SGD 15 per square foot. Lock down specifics.
What brands and grades of materials are you quoting?
Demand specific brands, models, and grades for every major material:
- Tiles: Brand (e.g., Hafary, Porcellanosa), finish (matt/glossy), size (600x600mm, 800x800mm)
- Laminate: Brand (e.g., Egger, Lamitak), thickness (0.8mm or 1mm), series/colour code
- Vinyl flooring: Brand (e.g., Bolon, Armstrong), thickness (2mm, 3mm, 5mm), wear layer rating
- Sanitary ware: Brand (e.g., Grohe, Hansgrohe, American Standard), model numbers
- Paint: Brand (e.g., Nippon, Dulux), grade (3-in-1, premium weathershield)
If the contractor says "contractor-grade" or "builder's choice," push for specifics. At Larry Contractors, our quotes include exact material codes. You can Google them before signing.
Can I see samples and past project photos?
Ask to visit the contractor's showroom or material yard. Check carpentry samples for edge banding quality, laminate finishes, and hinge brands (Hettich and Blum are gold standards). Request photos of completed projects similar to yours—not just staged showroom shots, but actual client homes 6-12 months post-completion. This reveals long-term workmanship quality.
What's the warranty on materials and workmanship?
Standard warranties in Singapore:
| Item | Typical Warranty |
|---|---|
| Carpentry workmanship | 12 months |
| Carpentry hinges/hardware | 12 months to lifetime (brand-dependent) |
| Painting | 12 months |
| Waterproofing | 12 months minimum, up to 60 months for premium systems |
| Electrical/plumbing workmanship | 12 months |
| Tiles installation | 12 months |
Confirm it's in the contract, not just verbal assurance. Ask about the defect rectification process: How quickly do you respond to warranty claims? Do you provide a temporary fix immediately and a permanent solution later?
Contract Terms and Dispute Resolution Questions
The contract protects both parties, but only if it's comprehensive. Too many homeowners sign contracts that are two-page wishlists, not enforceable agreements.
What does the contract include?
A proper renovation contract in Singapore should specify:
- Full scope of works (reference the detailed quotation)
- Payment schedule and amounts
- Project start and completion dates with allowable delay provisions
- Material specifications (or reference to approved material list)
- Warranty terms for workmanship and materials
- Defect liability period (typically 12 months from handover)
- Variation order process and pricing
- Dispute resolution mechanism
- Termination clauses for both parties
- Contractor's license numbers, insurance details, contact information
What happens if there are delays?
Discuss realistic delay scenarios: permit approval taking longer than expected, back-ordered materials, manpower shortages. Ethical contractors include a clause allowing reasonable delays due to unforeseen circumstances but commit to notifying you immediately. Ask: If the delay is your fault, do I get compensation? Some contracts include liquidated damages (e.g., SGD 100-300 per day past the completion date), though this is rare for residential projects under SGD 100,000.
How are disputes resolved?
Hope for the best, plan for the worst. Ask whether the contract includes mediation or arbitration clauses. Singapore's Small Claims Tribunals handle claims up to SGD 30,000 (SGD 50,000 with consent). For larger projects, you want a dispute resolution process that doesn't require immediate litigation. At Larry Contractors, we've completed 500+ projects since 2009 with disputes resolved through direct dialogue—our reputation depends on it.
Frequently Asked Questions
How much deposit should I pay a renovation contractor in Singapore?
Pay no more than 30% upfront. Standard practice is a 30-20-20-20-10% milestone schedule. Contractors requesting 50% or more before work starts carry higher risk. The deposit covers initial material procurement and mobilisation. Retain at least 10% until all defects are rectified. Never pay the full amount before project completion, regardless of rapport or promises.
Do I need to hire a separate ID if I engage a direct contractor?
No. Direct contractors like Larry Contractors handle design, material selection, and execution without an interior designer middleman. You work directly with the project manager and, if needed, an in-house designer for space planning and 3D visuals. This saves the 20-30% ID margin. Hire an ID separately only if you want complex custom designs beyond standard reno scope or need help with conceptualisation.
Can a contractor start work before HDB approval is granted?
No. HDB requires approval before any renovation work begins. Starting early risks a stop-work order, fines, and project delays. The approval process takes 7-14 days for standard applications. Plan accordingly. Your contractor should submit the application immediately after contract signing. You'll receive an approval letter via SMS or email; keep it onsite for HDB inspections.
What should I do if my contractor disappears mid-project?
First, document everything: contract, payment receipts, photos, messages. Attempt contact via all channels (phone, email, registered address). If unresponsive for over a week, file a report with CASE (Consumers Association of Singapore) and consider Small Claims Tribunal action. Check if the contractor is HDB-licensed—report license violations to HDB, which can suspend or revoke licenses. To avoid this scenario, verify licensing upfront and never pay more than the milestone warrants.
How do I verify a contractor's HDB license is valid?
Visit HDB's InfoWEB, search for "Register of Licensed Renovation Contractors," and enter the license number (format: HB-XX-XXXXH). The register shows the contractor's name, license validity, and registration status. Screenshot it for your records. Unlicensed contractors cannot legally renovate HDB flats. If caught, HDB halts the project, and you're liable for engaging an unlicensed party. Always verify before signing.
