Budget for 10–14 weeks total on a full-flat renovation to stay on the safe side.<h3>Smart Ways to Cut Your HDB Renovation Budget</h3>A tight budget doesn't mean compromising on quality. These approaches help experienced homeowners keep costs in check.Hack selectively. Every wall you hack adds cost and may require an HDB permit. Preserve what's structurally sound and update cosmetically where possible.Source materials yourself. Many contractors mark up materials by 20–40%. For tiles, laminate flooring, and sanitary ware, visit suppliers directly in Geylang, Joo Chiat, or Balestier to compare prices before your renovation starts.Choose vinyl over marble. Luxury vinyl tiles (LVT) can replicate marble or stone looks at a fraction of the cost — typically $3–$6 per square foot versus $15–$30 for genuine marble.<figure class="image"><img style="aspect-ratio:1337/729;" src="https://d213h1b7vxzzl3.cloudfront.net/editor/3d58f890-35cd-4fed-ae06-bcaac163220b-blob" width="1337" height="729"></figure>Compare renovation packages. Some renovation companies offer full-flat packages for 3-room HDB flats starting at $25,000–$30,000. Always compare at least three quotes before committing.Prioritise kitchens and bathrooms. These are the hardest and most expensive rooms to redo later. Invest here, and you can always repaint a bedroom wall down the track. &nbsp;<h3>How to Find a Reliable HDB Renovation Contractor</h3>Choosing the right contractor matters more than any design decision. A poorly managed renovation can drag on for months and leave you with shoddy workmanship.Check for HDB registration. HDB-registered contractors are vetted and can submit permit applications directly. Verify their registration status on the HDB website before signing anything.Review completed projects. Ask for photos of similar HDB flats they've renovated — ideally the same flat size as yours. Read verified reviews on renovation platforms and HDB renovation forums.Get three detailed quotes. Compare line-item breakdowns, not just totals. Vague quotes that lump everything into one figure are a red flag — you want to see material specs, brands, and quantities listed separately.Use <a href="https://www.renonation.sg/professionals">find interior designers Singapore</a> on Renonation.sg to browse verified renovation professionals with HDB project portfolios, customer ratings, and style galleries — all in one place.<h3>Frequently Asked Questions About HDB Renovation Ideas Singapore</h3>Do I need an HDB permit for a full renovation?
