Questions to Ask Before Hiring a Renovation Contractor in Singapore

Top 10 questions before hiring your renovation contractor

When it comes to home renovation, hiring the right contractor can make or break your project. With countless renovation contractors in Singapore, it’s essential to ask the right questions before signing any agreement.

Here are the top 10 questions you should always ask to ensure you choose a reliable and professional renovation contractor.

1. Are You HDB-Registered?

If you’re renovating a BTO or resale HDB flat, your contractor must be HDB-licensed. This ensures compliance with HDB renovation guidelines and prevents costly mistakes. We are registered under Lam’s Carpenter Pte Ltd – HDB Licence No. HB-11-6266D

đź–Ś Pro Tip: Ask for their HDB license number and verify it on the HDB Directory.

2. Can I See Your Past Projects or Portfolio?

Reviewing a contractor’s past work gives you insight into their quality and design style. A good portfolio should showcase before-and-after photos, space optimisation, and carpentry craftsmanship.

3. Can You Provide a Detailed Quote?

Avoid vague estimates. A trustworthy contractor should break down costs by category—carpentry, electrical, masonry, etc.—so you can understand where your money is going.

4. Who Will Be Managing My Project?

You want a dedicated project manager who’s your point of contact, not different people showing up every day. Ask if you’ll have updates throughout the renovation.

5. What’s the Estimated Timeline?

Time is money—especially if you’re renting elsewhere during your renovation. Always get a timeline in writing, with allowances for potential delays.

6. Are There Any Hidden Costs?

Ask clearly: “Is this the final cost, or could additional charges appear later?” This helps you avoid “quote shocks” after work begins.

7. Do You Offer a Warranty?

A professional contractor will stand by their work. Look for a warranty on workmanship (typically 1–2 years) and a clear aftercare process for touch-ups or defects.

8. What’s Your Payment Schedule?

Never pay 100% upfront. A fair payment schedule might be:

  • 10% deposit

  • 40% after material delivery

  • 40% mid-way

  • 10% after final inspection

9. Do You Outsource Your Work or Use In-House Teams?

Knowing whether your renovation is handled by in-house carpenters or outsourced to sub-contractors can affect consistency, quality, and accountability.

10. Can I Speak to Past Clients?

Reputable contractors should offer references or reviews. If they’re hesitant, that’s a red flag.

Choosing a renovation contractor isn’t just about the cheapest price. It’s about trust, transparency, and long-term satisfaction.
