Choosing the right renovation contractor in Singapore can mean the difference between a dream home and a costly nightmare. The average HDB renovation costs $40,000–$70,000, and picking the wrong contractor is the number-one reason projects go over budget or drag past deadline. This guide walks you through exactly how to vet, compare, and hire a renovation contractor — whether you are renovating an HDB flat, condo, or landed property.This guide is for informational purposes. Prices and regulations may change — always verify with HDB, BCA, or your interior designer.<h3>Why Your Choice of Contractor Matters</h3><figure class="image"><img style="aspect-ratio:1200/800;" src="https://d213h1b7vxzzl3.cloudfront.net/editor/fd56dfa6-b91e-4d57-bf16-56ab04692a8f-blob" width="1200" height="800"></figure>Your renovation contractor controls the quality of workmanship, the project timeline, and ultimately how much you spend. According to the Consumers Association of Singapore (CASE), renovation disputes consistently rank among the top complaint categories each year. Common issues include incomplete work, poor finishing, unexpected cost overruns, and contractors disappearing mid-project.A reliable contractor gives you a detailed quotation, sticks to agreed timelines, communicates proactively about delays, and provides a proper warranty. An unreliable one may cut corners on materials, subcontract work without telling you, or demand large upfront payments before starting.The stakes are high — especially for first-time homeowners. Our <a href="https://www.renonation.sg/articles/renovation-cost-singapore-2026-complete-price-guide-for-hdb-condo--landed">renovation cost Singapore 2026 guide</a> breaks down exactly what you should expect to pay, so you can spot inflated quotes before signing.<h3>Types of Renovation Contractors in Singapore</h3>Not all renovation contractors are the same. Understanding the different types helps you match the right professional to your project scope and budget.<figure class="table"><table><tbody><tr><td>Contractor Type</td><td>Best For</td><td>Typical Cost Range</td><td>Pros</td><td>Cons</td></tr><tr><td>Design-and-build firm</td><td>Full home renovation</td><td>$50,000–$120,000+</td><td>One-stop solution, design included</td><td>Higher cost, less flexibility</td></tr><tr><td>Main contractor</td><td>Large-scale structural work</td><td>$60,000–$150,000+</td><td>Handles permits, subcontractors</td><td>Less design input</td></tr><tr><td>Direct contractor</td><td>Specific trades (plumbing, electrical)</td><td>$5,000–$30,000</td><td>Lower cost, specialised skills</td><td>Need to coordinate multiple trades</td></tr><tr><td>Interior design firm</td><td>Design-led renovations</td><td>$40,000–$100,000+</td><td>Strong aesthetics, project management</td><td>Premium pricing for design fees</td></tr></tbody></table></figure>Source: Renonation.sg market research, 2026For HDB flats, you must use an HDB-registered renovation contractor for any work that involves hacking, electrical rewiring, or plumbing changes. You can verify registration through <a href="https://www.renonation.sg/professionals">Renonation.sg's professional directory</a> or the HDB InfoWEB.Not sure what an interior designer actually does versus a contractor? This article on the <a href="https://www.renonation.sg/articles/11-responsibilities-of-an-interior-designer">11 responsibilities of an interior designer</a> clarifies the differences.For condos, your contractor must comply with your Management Corporation Strata Title (MCST) rules — this body governs renovation hours, permitted works, and deposit requirements. Landed property renovations may require URA (Urban Redevelopment Authority) planning permission for additions and alterations.<h3>How to Vet a Renovation Contractor (Step-by-Step)</h3><figure class="image"><img style="aspect-ratio:1200/800;" src="https://d213h1b7vxzzl3.cloudfront.net/editor/6006ca4d-bd4d-4c54-ab63-1dfe1970c6e9-blob" width="1200" height="800"></figure>Step 1: Check Licences and Registration Every renovation contractor working on HDB flats must be HDB-registered. For general building works, check if they hold a BCA (Building and Construction Authority) licence. Ask for their registration number and verify it online. This is non-negotiable — unlicensed contractors have no accountability if things go wrong.Step 2: Review Their Portfolio Ask for at least five completed projects similar to yours. A contractor experienced with 4-room HDB flats may not be the best fit for a landed property rebuild. Look for consistency in quality and pay attention to before-and-after photos.Step 3: Get at Least 3 Quotes Request detailed quotations from at least three contractors. Each quote should break down costs by room and work type — not just a lump sum. Compare like-for-like: materials, brands, and scope. You can quickly get free renovation quotes on Renonation.sg to jumpstart this process.Step 4: Check Reviews and References Read online reviews on platforms like Renonation.sg, Google, and Facebook. Ask the contractor for two to three references you can contact directly. Speaking to past clients tells you more than any brochure.Step 5: Understand the Payment Schedule A fair payment schedule ties payments to project milestones — not calendar dates. Never pay more than 10% upfront. The industry standard is a progressive payment structure: 10% deposit, then payments at hacking completion, carpentry installation, painting, and final handover.<figure class="table"><table><tbody><tr><td>Milestone</td><td>Typical Payment %</td><td>What Should Be Completed</td></tr><tr><td>Contract signing</td><td>10%</td><td>Agreement signed, permits applied</td></tr><tr><td>Hacking &amp; masonry done</td><td>20%</td><td>Walls hacked, new walls built, waterproofing</td></tr><tr><td>Electrical &amp; plumbing done</td><td>20%</td><td>Rewiring, pipe relocation, false ceiling frame</td></tr><tr><td>Carpentry installation</td><td>25%</td><td>Kitchen cabinets, wardrobes, feature walls</td></tr><tr><td>Painting &amp; final fixtures</td><td>15%</td><td>Painting, lighting, sanitary ware installed</td></tr><tr><td>Handover &amp; defects check</td><td>10%</td><td>Final inspection, defects list agreed</td></tr></tbody></table></figure>Source: Industry standard progressive payment structure<h3>Renovation Contractor Cost Comparison 2026</h3>Renovation costs in Singapore vary widely based on property type, scope, and contractor tier.

These <a href="https://www.renonation.sg/articles/10-areas-to-watch-out-for-before-signing-a-renovation-contract">10 key areas to check before signing a renovation contract</a> are essential reading before you commit. Here are the most common red flags:Demanding more than 50% payment upfront is a major warning sign. Legitimate contractors follow progressive payment schedules tied to milestones. If a contractor wants half the money before lifting a hammer, walk away.Vague quotations that bundle everything into a single line item make it impossible to compare prices or track costs. Insist on itemised quotes that break down materials, labour, and design fees separately.No written contract is a dealbreaker. Every agreement should be documented — including scope of work, timeline, payment schedule, warranty terms, and the Defects Liability Period (DLP). The DLP is the window after handover (typically 12 months) where your contractor must fix any defects for free.Contractors who pressure you to sign immediately or offer "today only" discounts are using high-pressure sales tactics.

Start by checking platforms like Renonation.sg that vet contractors and display verified reviews. Get at least three quotes, verify BCA or HDB registration, review their portfolio, and speak to past clients before committing.How much should I pay upfront to a renovation contractor? The industry standard is a 10% deposit upon contract signing. Avoid any contractor who demands more than 20% upfront. Payments should follow a progressive schedule tied to completed milestones — not arbitrary dates.What is the Defects Liability Period (DLP)? The Defects Liability Period is a warranty window (usually 12 months) after your renovation handover during which the contractor must repair any defects at no extra cost. Make sure your contract includes a clear DLP clause.Do I need an HDB-registered contractor for my HDB renovation? Yes.

You can check registration status on HDB InfoWEB.What is the difference between a contractor and an interior designer? A contractor focuses on construction and installation work. An interior designer handles aesthetics, space planning, and design concepts. Many Singapore firms offer design-and-build services that combine both under one roof.How long does a typical HDB renovation take? Most HDB renovations take 8 to 12 weeks from hacking to handover. Complex projects or those involving BCA permit applications may take longer. Always build a two-week buffer into your timeline.Can I renovate a condo without MCST approval? Minor cosmetic works like painting or changing light fixtures usually do not require MCST approval.
