When renovating your HDB BTO flat in Singapore, carpentry often takes up a significant portion of your budget. Yet many homeowners focus on design and material finishes, and overlook the importance of selecting the right carpentry sub-contractor: one who is HDB-compliant, uses quality materials, meets timelines, and provides warranties.
This guide helps you understand what many first-time BTO owners miss when hiring carpentry subcontractors — and how choosing wisely can save time, cost and stress.
1. Why the Carpentry Sub-Contractor Matters
- For built-in wardrobes, kitchen cabinets, TV feature walls: poor workmanship or delays == major inconvenience.
- HDB flats have specific regulations (e.g., cabinetry near wet areas, built-ins over service ducts) — wrong vendor may lead to non-compliance.
- The subcontractor’s materials, hardware, finishing quality affect durability → warping, peeling, misalignment.
- Lead time for carpentry often dictates your move-in date. Choosing the right team ensures smoother timeline.
2. Key Criteria to Evaluate When Hiring a Carpentry Sub-Contractor
2.1 HDB-Compliance & Experience
- Are they listed under HDB’s Renovation Contractor Directory (RDOC) if required?
- Have they done BTO projects (not just landed or condo) before?
2.2 Material Standards & Hardware Quality
- What board grade: E0 vs E1? What laminate finish?
- What hardware (hinges/sliders) brands? What warranties?
2.3 Production & Installation Timeline
- How long from measurement to factory fabrication to on-site install?
- Do they have capacity for batch production / group projects for faster turnaround?
2.4 Warranty & After-Sales Support
- What warranty for workmanship, materials, hardware? 1yr? 3yrs?
- Do they offer rectification of defects (e.g., warping, door misalignment) within warranty?
2.5 Transparency in Quotation & Payment Milestones
- Itemised breakdown: carpentry works, materials, labour, delivery, installation.
- Avoid large upfront payment; milestone payments better.
2.6 Communication & Proof of Workmanship
- Do they provide 3D mockups or virtual tours?
- Can you visit previous completed units? Are there testimonials/photos?
3. Common Mistakes Homeowners Make When Engaging Carpentry Sub-Contractors
- Choosing cheapest quote without checking materials/hardware quality → cost blow up later.
- Finalising design after fabrication begins → changes lead to extra cost and delay.
- Not verifying board grade or hardware brand → early defects.
- Lack of clarity on lead times → move-in delayed.
- No proper warranty documentation or after-sales support plan.
4. Checklist for Hiring & Managing Your Carpentry Sub-Contractor
- Confirm board & laminate grades (E0, low-VOC)
- Hardware brand and soft-close mechanism tested
- Factory lead-time & on-site installation timeline confirmed
- Payment schedule: deposit + production + delivery + handover
- Visit showroom or completed units if possible
- Ensure contract includes warranty + defect rectification clause
- Coordinate with your ID/renovation contractor so carpentry fits with flooring/painting schedule
